  • Are there supposed to be more restrictions on operator->* overloads?

    - by Potatoswatter
    I was perusing section 13.5 after refuting the notion that built-in operators do not participate in overload resolution, and noticed that there is no section on operator->*. It is just a generic binary operator. Its brethren, operator->, operator*, and operator[], are all required to be non-static member functions. This precludes definition of a free function overload to an operator commonly used to obtain a reference from an object. But the uncommon operator->* is left out. In particular, operator[] has many similarities. It is binary (they missed a golden opportunity to make it n-ary), and it accepts some kind of container on the left and some kind of locator on the right. Its special-rules section, 13.5.5, doesn't seem to have any actual effect except to outlaw free functions. (And that restriction even precludes support for commutativity!) So, for example, this is perfectly legal (in C++0x, remove obvious stuff to translate to C++03): #include <utility> #include <iostream> #include <type_traits> using namespace std; template< class F, class S > typename common_type< F,S >::type operator->*( pair<F,S> const &l, bool r ) { return r? l.second : l.first; } template< class T > T & operator->*( pair<T,T> &l, bool r ) { return r? l.second : l.first; } template< class T > T & operator->*( bool l, pair<T,T> &r ) { return l? r.second : r.first; } int main() { auto x = make_pair( 1, 2.3 ); cerr << x->*false << " " << x->*4 << endl; auto y = make_pair( 5, 6 ); y->*(0) = 7; y->*0->*y = 8; // evaluates to 7->*y = y.second cerr << y.first << " " << y.second << endl; } I can certainly imagine myself giving into temp[la]tation. For example, scaled indexes for vector: v->*matrix_width[5] = x; Did the standards committee forget to prevent this, was it considered too ugly to bother, or are there real-world use cases?

  • GoogleTv video using VideoView is clipped, even though its in a separate layout of its own

    - by MYR
    Wrote an application for GoogleTV box to play a video. The video is a separate activity to the main activity. Wired up a button on my main layout/activity to to start the video activity up (using its own video.xml layout), the video activity loads and starts playing, but the video is clipped, only showing a few centimetres of the bottom. The clipped region looks like the views that occupied the previous layout (main.xml) . The intriguing thing is that if I push the back button, before returning to the main activity the full video frame is shown. Not sure what I am doing wrong here. Any suggestions welcome. Code: main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/hello_message" android:layout_width="fill_parent" android:layout_height="200dp" android:gravity="center" android:text="@string/hello_message" android:textSize="78sp" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <EditText android:id="@+id/edit_message" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:ems="10" android:hint="@string/edit_message" > <requestFocus /> </EditText> <Button android:id="@+id/button_send" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="displayMessage" android:text="@string/button_send" /> <Button android:id="@+id/button_send_a" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="sendMesssage" android:text="@string/button_send_a" /> </LinearLayout> <Button android:id="@+id/videobutton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="startAVideo" android:text="Video Player" /> </LinearLayout> GoogleTVExActivity.java (excerpt): ... public class GoogleTVExActivity extends Activity { public final static String EXTRA_MESSAGE = "uk.co.bbc.googletvex.MESSAGE"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public void displayMessage(View view) { TextView t = (TextView)findViewById(R.id.hello_message); EditText e =(EditText) findViewById(R.id.edit_message); t.setText(e.getText().toString()); e.setText(""); } public void sendMesssage(View view) { Intent intent = new Intent(this, DisplayMessageActivity.class); EditText editText = (EditText) findViewById(R.id.edit_message); String message = editText.getText().toString(); intent.putExtra(EXTRA_MESSAGE, message); startActivity(intent); } public void startAVideo(View view) { Intent intent = new Intent(this, VideoViewActivity.class); startActivity(intent); } } video.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <VideoView android:id="@+id/myvideoview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> VideoViewActivity.java (excerpt) ... import android.app.Activity; import android.net.Uri; import android.os.Bundle; import android.widget.MediaController; import android.widget.VideoView; public class VideoViewActivity extends Activity { String SrcPath = "rtsp://v5.cache1.c.youtube.com/CjYLENy73wIaLQnhycnrJQ8qmRMYESARFEIJbXYtZ29vZ2xlSARSBXdhdGNoYPj_hYjnq6uUTQw=/0/0/0/video.3gp"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.video); VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview); myVideoView.setVideoURI(Uri.parse(SrcPath)); myVideoView.setMediaController(new MediaController(this)); myVideoView.requestFocus(); myVideoView.start(); } }

  • Android passing an arraylist back to parent activity

    - by Nicklas O
    Hi there. I've been searching for a simple example of this with no luck. In my android application I have two activities: 1. The main activity which is launched at startup 2. A second activity which is launched by pressing a button on the main activty. When the second activity is finished (by pressing a button) I want it to send back an ArrayList of type MyObject to the main activity and close itself, which the main activity can then do whatever with it. How would I go about achieving this? I have been trying a few things but it is crashing my application when I start the second activity. When the user presses button to launch second activity: Intent i = new Intent(MainActivity.this, secondactivity.class); startActivityForResult(i, 1); The array which is bundled back after pressing a button on the second activity: Intent intent= getIntent(); Bundle b = new Bundle(); b.putParcelableArrayList("myarraylist", mylist); intent.putExtras(b); setResult(RESULT_OK, intent); finish(); And finally a listener on the main activity (although I'm not sure of 100% when this code launches...) protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(resultCode==RESULT_OK && requestCode==1){ Bundle extras = data.getExtras(); final ArrayList<MyObject> mylist = extras.getParcelableArrayList("myarraylist"); Toast.makeText(MainActivity.this, mylist.get(0).getName(), Toast.LENGTH_SHORT).show(); } } Any ideas where I am going wrong? The onActivityResult() seems to be crashing my application. EDIT: This is my class MyObject, its called plan and has a name and an id import android.os.Parcel; import android.os.Parcelable; public class Plan implements Parcelable{ private String name; private String id; public Plan(){ } public Plan(String name, String id){ this.name = name; this.id = id; } public String getName(){ return name; } public void setName(String name){ this.name = name; } public String getId(){ return id; } public void setId(String id){ this.id = id; } public String toString(){ return "Plan ID: " + id + " Plan Name: " + name; } @Override public int describeContents() { // TODO Auto-generated method stub return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(id); dest.writeString(name); } public static final Parcelable.Creator<Plan> CREATOR = new Parcelable.Creator<Plan>() { public Plan createFromParcel(Parcel in) { return new Plan(); } @Override public Plan[] newArray(int size) { // TODO Auto-generated method stub return new Plan[size]; } }; } This is my logcat E/AndroidRuntime( 293): java.lang.RuntimeException: Unable to instantiate activ ity ComponentInfo{com.daniel.android.groupproject/com.me.android.projec t.secondactivity}: java.lang.NullPointerException E/AndroidRuntime( 293): at android.app.ActivityThread.performLaunchActiv ity(ActivityThread.java:2417) E/AndroidRuntime( 293): at android.app.ActivityThread.handleLaunchActivi ty(ActivityThread.java:2512) E/AndroidRuntime( 293): at android.app.ActivityThread.access$2200(Activi tyThread.java:119) E/AndroidRuntime( 293): at android.app.ActivityThread$H.handleMessage(Ac tivityThread.java:1863) E/AndroidRuntime( 293): at android.os.Handler.dispatchMessage(Handler.ja va:99) E/AndroidRuntime( 293): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 293): at android.app.ActivityThread.main(ActivityThrea d.java:4363) E/AndroidRuntime( 293): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 293): at java.lang.reflect.Method.invoke(Method.java:5 21) E/AndroidRuntime( 293): at com.android.internal.os.ZygoteInit$MethodAndA rgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 293): at com.android.internal.os.ZygoteInit.main(Zygot eInit.java:618) E/AndroidRuntime( 293): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 293): Caused by: java.lang.NullPointerException E/AndroidRuntime( 293): at com.daniel.android.groupproject.login.<init>( login.java:51) E/AndroidRuntime( 293): at java.lang.Class.newInstanceImpl(Native Method ) E/AndroidRuntime( 293): at java.lang.Class.newInstance(Class.java:1479) E/AndroidRuntime( 293): at android.app.Instrumentation.newActivity(Instr umentation.java:1021) E/AndroidRuntime( 293): at android.app.ActivityThread.performLaunchActiv ity(ActivityThread.java:2409) E/AndroidRuntime( 293): ... 11 more

  • Fluent Nhibernate - how do i specify table schemas when auto generating tables in SQL CE 4

    - by daffers
    I am using SQL CE as a database for running local and CI integration tests (normally our site runs on normal SQL server). We are using Fluent Nhibernate for our mapping and having it create our schema from our Mapclasses. There are only two classes with a one to many relationship between them. In our real database we use a non dbo schema. The code would not work with this real database at first until i added schema names to the Table() methods. However doing this broke the unit tests with the error... System.Data.SqlServerCe.SqlCeException : There was an error parsing the query. [ Token line number = 1,Token line offset = 26,Token in error = User ] These are the classes and associatad MapClasses (simplified of course) public class AffiliateApplicationRecord { public virtual int Id { get; private set; } public virtual string CompanyName { get; set; } public virtual UserRecord KeyContact { get; private set; } public AffiliateApplicationRecord() { DateReceived = DateTime.Now; } public virtual void AddKeyContact(UserRecord keyContactUser) { keyContactUser.Affilates.Add(this); KeyContact = keyContactUser; } } public class AffiliateApplicationRecordMap : ClassMap<AffiliateApplicationRecord> { public AffiliateApplicationRecordMap() { Schema("myschema"); Table("Partner"); Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.CompanyName, "Name"); References(x => x.KeyContact) .Cascade.All() .LazyLoad(Laziness.False) .Column("UserID"); } } public class UserRecord { public UserRecord() { Affilates = new List<AffiliateApplicationRecord>(); } public virtual int Id { get; private set; } public virtual string Forename { get; set; } public virtual IList<AffiliateApplicationRecord> Affilates { get; set; } } public class UserRecordMap : ClassMap<UserRecord> { public UserRecordMap() { Schema("myschema"); Table("[User]");//Square brackets required as user is a reserved word Id(x => x.Id).GeneratedBy.Identity(); Map(x => x.Forename); HasMany(x => x.Affilates); } } And here is the fluent configuraton i am using .... public static ISessionFactory CreateSessionFactory() { return Fluently.Configure() .Database( MsSqlCeConfiguration.Standard .Dialect<MsSqlCe40Dialect>() .ConnectionString(ConnectionString) .DefaultSchema("myschema")) .Mappings(m => m.FluentMappings.AddFromAssembly(typeof(AffiliateApplicationRecord).Assembly)) .ExposeConfiguration(config => new SchemaExport(config).Create(false, true)) .ExposeConfiguration(x => x.SetProperty("connection.release_mode", "on_close")) //This is included to deal with a SQLCE issue http://stackoverflow.com/questions/2361730/assertionfailure-null-identifier-fluentnh-sqlserverce .BuildSessionFactory(); } The documentation on this aspect of fluent is pretty weak so any help would be appreciated

  • Trouble with setting entry point for GWT service

    Hello. I've followed serveral tutorials and read official docs at code.google.com, but still didn't manage to resolve this thing. I am creating simple service that'll check if user can be logged. CLIENT SIDE: public interface LoginService extends RemoteService { /** * Checks, if user has valid login. * @param user User's login. * @return True if such a login is in the database. */ boolean isValidUser(User user); } And here is Async interface: public interface LoginServiceAsync { /** * Checks, if user has valid login. * @param user User's login. * @param callback the callback to return True if such a login is in the database. */ void isValidUser(User user, AsyncCallback<Boolean> callback); } SERVER SIDE: public class LoginServiceImpl extends RemoteServiceServlet implements LoginService { /** * serial version UID */ private static final long serialVersionUID = 1044980345057997696L; /**{@inheritDoc} */ @Override public boolean isValidUser(User user) { boolean success = true; //TODO change } } Now I have entry point class MailClient.java.

  • Strange problem with Google App Engine Java Mail

    - by Velu
    Hi, I'm using the MailService feature of Google App Engine in my application. It works fine in one application without any issues. But the same code doesn't work in another app. I'm not able to figure it out. Please help. Following is the piece of code that I use to send mail. public static void sendHTMLEmail(String from, String fromName, String to, String toName, String subject, String body) { _logger.info("entering ..."); Properties props = new Properties(); Session session = Session.getDefaultInstance(props, null); _logger.info("got mail session ..."); String htmlBody = body; try { Message msg = new MimeMessage(session); _logger.info("created mimemessage ..."); msg.setFrom(new InternetAddress(from, fromName)); _logger.info("from is set ..."); msg.addRecipient(Message.RecipientType.TO, new InternetAddress( to, toName)); _logger.info("recipient is set ..."); msg.setSubject(subject); _logger.info("subject is set ..."); Multipart mp = new MimeMultipart(); MimeBodyPart htmlPart = new MimeBodyPart(); htmlPart.setContent(htmlBody, "text/html"); mp.addBodyPart(htmlPart); _logger.info("body part added ..."); msg.setContent(mp); _logger.info("content is set ..."); Transport.send(msg); _logger.info("email sent successfully."); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); System.err.println(e.getMessage()); } } When I look at the log (on the server admin console), it prints the statement "content is set ..." and after that there is nothing in the log. The mail is not sent. At times I get the following error after the above statement is printed (and the mail is not sent). com.google.appengine.repackaged.com.google.common.base.internal.Finalizer getInheritableThreadLocalsField: Couldn't access Thread.inheritableThreadLocals. Reference finalizer threads will inherit thread local values. But the mail quota usage keeps increasing. Remember, this works fine in one application, but not in other. I'm using the same set of email addresses in both the apps (for from and to). I'm really stuck with this. Appreciate any help. Thank you. Velu

  • Java client listening to WebSphere MQ Server?

    - by user595234
    I need to write a Java client listening to WebSphere MQ Server. Message is put into a queue in the server. I developed this code, but am not sure it is correct or not. If correct, then how can I test it? This is a standalone Java project, no application server support. Which jars I should put into classpath? I have the MQ settings, where I should put into my codes? Standard JMS can skip these settings? confusing .... import javax.jms.Destination; import javax.jms.Message; import javax.jms.MessageConsumer; import javax.jms.MessageListener; import javax.jms.Queue; import javax.jms.QueueConnection; import javax.jms.QueueConnectionFactory; import javax.jms.QueueReceiver; import javax.jms.QueueSession; import javax.jms.Session; import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; public class Main { Context jndiContext = null; QueueConnectionFactory queueConnectionFactory = null; QueueConnection queueConnection = null; QueueSession queueSession = null; Queue controlQueue = null; QueueReceiver queueReceiver = null; private String queueSubject = ""; private void start() { try { queueConnection.start(); queueSession = queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE); Destination destination = queueSession.createQueue(queueSubject); MessageConsumer consumer = queueSession.createConsumer(destination); consumer.setMessageListener(new MyListener()); } catch (Exception e) { e.printStackTrace(); } } private void close() { try { queueSession.close(); queueConnection.close(); } catch (Exception e) { e.printStackTrace(); } } private void init() { try { jndiContext = new InitialContext(); queueConnectionFactory = (QueueConnectionFactory) this.jndiLookup("QueueConnectionFactory"); queueConnection = queueConnectionFactory.createQueueConnection(); queueConnection.start(); } catch (Exception e) { System.err.println("Could not create JNDI API " + "context: " + e.toString()); System.exit(1); } } private class MyListener implements MessageListener { @Override public void onMessage(Message message) { System.out.println("get message:" + message); } } private Object jndiLookup(String name) throws NamingException { Object obj = null; if (jndiContext == null) { try { jndiContext = new InitialContext(); } catch (NamingException e) { System.err.println("Could not create JNDI API " + "context: " + e.toString()); throw e; } } try { obj = jndiContext.lookup(name); } catch (NamingException e) { System.err.println("JNDI API lookup failed: " + e.toString()); throw e; } return obj; } public Main() { } public static void main(String[] args) { new Main(); } } MQ Queue setting <queue-manager> <name>AAA</name> <port>1423</port> <hostname>ddd</hostname> <clientChannel>EEE.CLIENTS.00</clientChannel> <securityClass>PKIJCExit</securityClass> <transportType>1</transportType> <targetClientMatching>1</targetClientMatching> </queue-manager> <queues> <queue-details id="queue-1"> <name>GGGG.NY.00</name> <transacted>false</transacted> <acknowledgeMode>1</acknowledgeMode> <targetClient>1</targetClient> </queue-details> </queues>

  • Is it possible to create the following XML using Xdocument and append the relevant protion in subseq

    - by Newbie
    <?xml version='1.0' encoding='UTF-8'?> <StockMarket> <StockDate Day = "02" Month="06" Year="2010"> <Stock> <Symbol>ABC</Symbol> <Amount>110.45</Amount> </Stock> <Stock> <Symbol>XYZ</Symbol> <Amount>366.25</Amount> </Stock> </StockDate> <StockDate Day = "03" Month="06" Year="2010"> <Stock> <Symbol>ABC</Symbol> <Amount>110.35</Amount> </Stock> <Stock> <Symbol>XYZ</Symbol> <Amount>369.70</Amount> </Stock> </StockDate> </StockMarket> My approach so far is XDocument doc = new XDocument( new XElement("StockMarket", new XElement("StockDate", new XAttribute("Day", "02"),new XAttribute("Month","06"),new XAttribute("Year","2010")), new XElement("Stock", new XElement("Symbol", "ABC"), new XElement("Amount", "110.45")) ) ); Since I am new to Linq to XML, I am presently struggling a lot and henceforth seeking for help. What I need is to generate the above XML programatically(I mean to say that some kind of looping...) The values will be passed from textbox and hence will be filled at runtime. At present the one which I have done is a kind of static one. This entire stuff has to be done at runtime. One more problem that I am facing is at the time of saving the record for the second time. Suppose first time I executed the code and saved it(Using the program I have done). Next time when I will try to save then only <StockDate Day = "xx" Month="xx" Year="xxxx"> <Stock> <Symbol>ABC</Symbol> <Amount>110.45</Amount> </Stock> <Stock> <Symbol>XYZ</Symbol> <Amount>366.25</Amount> </Stock> </StockDate> should get save(or better appended) and not <StockMarket> .... </StockMarket>.. Because that will be created only at the first time when the XML will be generated or created. I hope I am able to convey my problem properly. If you people is having difficulty in understanding my situation, kindly let me know. Using C#3.0 . Thanks

  • App is crashing as soon as UITableView gets reloaded

    - by OhhMee
    Hello, I'm developing an app where TableView needs to reload as soon as the login process gets completed. The app crashes with error EXC_BAD_ACCESS when the table data gets reloaded. It doesn't crash when I remove all case instances except case 0: What could be the reason behind it? Here's the code: - (void)viewDidLoad { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loginDone:) name:@"loginDone" object:nil]; statTableView.backgroundColor = [UIColor clearColor]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger) section { return 6; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } // Configure the cell. switch (indexPath.row) { case 0 : cell.textLabel.text = @"Foo:"; NSLog(@"%@", data7); UILabel *myLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 20, 30)]; myLabel2.text = (@"%@", data7); myLabel2.textColor = [UIColor blackColor]; myLabel2.backgroundColor = [UIColor whiteColor]; myLabel2.font = [UIFont fontWithName:@"Trebuchet MS" size:14]; [cell.contentView addSubview:myLabel2]; break; case 1: cell.textLabel.text = @"Foo: "; UILabel *myLabel4 = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 20, 30)]; myLabel4.text = (@"%@", data11); myLabel4.textColor = [UIColor blackColor]; myLabel4.backgroundColor = [UIColor whiteColor]; myLabel4.font = [UIFont fontWithName:@"Trebuchet MS" size:14]; [cell.contentView addSubview:myLabel4]; break; case 2: cell.textLabel.text = @"Foo: "; UILabel *myLabel8 = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 20, 30)]; myLabel8.text = (@"%@", data3); myLabel8.textColor = [UIColor blackColor]; myLabel8.backgroundColor = [UIColor whiteColor]; myLabel8.font = [UIFont fontWithName:@"Trebuchet MS" size:14]; [cell.contentView addSubview:myLabel8]; break; case 3: cell.textLabel.text = @"Foo: "; UILabel *myLabel10 = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 20, 30)]; myLabel10.text = [NSString stringWithFormat:@"%@", data4]; if ([data4 isEqualToString:@"0"]) { myLabel10.text = @"None"; } myLabel10.textColor = [UIColor blackColor]; myLabel10.backgroundColor = [UIColor whiteColor]; myLabel10.font = [UIFont fontWithName:@"Trebuchet MS" size:14]; [cell.contentView addSubview:myLabel10]; break; case 4: cell.textLabel.text = @"Foo: "; UILabel *myLabel12 = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 20, 30)]; myLabel12.text = [NSString stringWithFormat:@"%@", data5]; myLabel12.textColor = [UIColor blackColor]; if ([data5 isEqualToString:@"Foo"]) { myLabel12.textColor = [UIColor redColor]; myLabel12.text = @"Nil"; } myLabel12.backgroundColor = [UIColor whiteColor]; myLabel12.font = [UIFont fontWithName:@"Trebuchet MS" size:14]; [cell.contentView addSubview:myLabel12]; break; case 5: cell.textLabel.text = @"Foo: "; UILabel *myLabel14 = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 50, 30)]; if ([data6 isEqualToString:@"Foo"]) { myLabel14.textColor = [UIColor colorWithRed:(0/255.f) green:(100/255.f) blue:(0/255.f) alpha:1.0]; myLabel14.text = @"No Dues"; } else { myLabel14.text = [NSString stringWithFormat:@"%@", data6]; myLabel14.textColor = [UIColor redColor]; } myLabel14.backgroundColor = [UIColor whiteColor]; myLabel14.font = [UIFont fontWithName:@"Trebuchet MS" size:14]; [cell.contentView addSubview:myLabel14]; break; /* [myLabel2 release]; [myLabel4 release]; [myLabel8 release]; [myLabel10 release]; [myLabel12 release]; [myLabel14 release]; */ } return cell; }

  • Where are the function address literals in c++?

    - by academicRobot
    First of all, maybe literals is not the right term for this concept, but its the closest I could think of (not literals in the sense of functions as first class citizens). <UPDATE> After some reading with help from answer by Chris Dodd, what I'm looking for is literal function addresses as template parameters. Chris' answer indicates how to do this for standard functions, but how can the addresses of member functions be used as template parameters? Since the standard prohibits non-static member function addresses as template parameters (c++03 14.3.2.3), I suspect the work around is quite complicated. Any ideas for a workaround? Below the original form of the question is left as is for context. </UPDATE> The idea is that when you make a conventional function call, it compiles to something like this: callq <immediate address> But if you make a function call using a function pointer, it compiles to something like this: mov <memory location>,%rax callq *%rax Which is all well and good. However, what if I'm writing a template library that requires a callback of some sort with a specified argument list and the user of the library is expected to know what function they want to call at compile time? Then I would like to write my template to accept a function literal as a template parameter. So, similar to template <int int_literal> struct my_template {...};` I'd like to write template <func_literal_t func_literal> struct my_template {...}; and have calls to func_literal within my_template compile to callq <immediate address>. Is there a facility in C++ for this, or a work around to achieve the same effect? If not, why not (e.g. some cataclysmic side effects)? How about C++0x or another language? Solutions that are not portable are fine. Solutions that include the use of member function pointers would be ideal. I'm not particularly interested in being told "You are a <socially unacceptable term for a person of low IQ>, just use function pointers/functors." This is a curiosity based question, and it seems that it might be useful in some (albeit limited) applications. It seems like this should be possible since function names are just placeholders for a (relative) memory address, so why not allow more liberal use (e.g. aliasing) of this placeholder. p.s. I use function pointers and functions objects all the the time and they are great. But this post got me thinking about the don't pay for what you don't use principle in relation to function calls, and it seems like forcing the use of function pointers or similar facility when the function is known at compile time is a violation of this principle, though a small one. Edit The intent of this question is not to implement delegates, rather to identify a pattern that will embed a conventional function call, (in immediate mode) directly into third party code, possibly a template.

  • why it throws index out of bounds exception??

    - by Johanna
    Hi I want to use merge sort for sorting my doubly linked list.I have created 3 classes(Node,DoublyLinkedList,MergeSort) but it will throw this exception for these lines: 1.in the getNodes method of DoublyLinkedList---> throw new IndexOutOfBoundsException(); 2.in the add method of DoublyLinkedList-----> Node cursor = getNodes(index); 3.in the sort method of MergeSort class------> listTwo.add(x,localDoublyLinkedList.getValue(x)); 4.in the main method of DoublyLinkedList----->merge.sort(); this is my Merge class:(I put the whole code for this class for beter understanding) public class MergeSort { private DoublyLinkedList localDoublyLinkedList; public MergeSort(DoublyLinkedList list) { localDoublyLinkedList = list; } public void sort() { if (localDoublyLinkedList.size() <= 1) { return; } DoublyLinkedList listOne = new DoublyLinkedList(); DoublyLinkedList listTwo = new DoublyLinkedList(); for (int x = 0; x < (localDoublyLinkedList.size() / 2); x++) { listOne.add(x, localDoublyLinkedList.getValue(x)); } for (int x = (localDoublyLinkedList.size() / 2) + 1; x < localDoublyLinkedList.size(); x++) { listTwo.add(x, localDoublyLinkedList.getValue(x)); } //Split the DoublyLinkedList again MergeSort sort1 = new MergeSort(listOne); MergeSort sort2 = new MergeSort(listTwo); sort1.sort(); sort2.sort(); merge(listOne, listTwo); } public void merge(DoublyLinkedList a, DoublyLinkedList b) { int x = 0; int y = 0; int z = 0; while (x < a.size() && y < b.size()) { if (a.getValue(x) < b.getValue(y)) { localDoublyLinkedList.add(z, a.getValue(x)); x++; } else { localDoublyLinkedList.add(z, b.getValue(y)); y++; } z++; } //copy remaining elements to the tail of a[]; for (int i = x; i < a.size(); i++) { localDoublyLinkedList.add(z, a.getValue(i)); z++; } for (int i = y; i < b.size(); i++) { localDoublyLinkedList.add(z, b.getValue(i)); z++; } } } and just a part of my DoublyLinkedList: private Node getNodes(int index) throws IndexOutOfBoundsException { if (index < 0 || index > length) { throw new IndexOutOfBoundsException(); } else { Node cursor = head; for (int i = 0; i < index; i++) { cursor = cursor.getNext(); } return cursor; } } public void add(int index, int value) throws IndexOutOfBoundsException { Node cursor = getNodes(index); Node temp = new Node(value); temp.setPrev(cursor); temp.setNext(cursor.getNext()); cursor.getNext().setPrev(temp); cursor.setNext(temp); length++; } public static void main(String[] args) { int i = 0; i = getRandomNumber(10, 10000); DoublyLinkedList list = new DoublyLinkedList(); for (int j = 0; j < i; j++) { list.add(j, getRandomNumber(10, 10000)); MergeSort merge = new MergeSort(list); merge.sort(); System.out.println(list.getValue(j)); } } PLEASE help me thanks alot.

  • Designing different Factory classes (and what to use as argument to the factories!)

    - by devoured elysium
    Let's say we have the following piece of code: public class Event { } public class SportEvent1 : Event { } public class SportEvent2 : Event { } public class MedicalEvent1 : Event { } public class MedicalEvent2 : Event { } public interface IEventFactory { bool AcceptsInputString(string inputString); Event CreateEvent(string inputString); } public class EventFactory { private List<IEventFactory> factories = new List<IEventFactory>(); public void AddFactory(IEventFactory factory) { factories.Add(factory); } //I don't see a point in defining a RemoveFactory() so I won't. public Event CreateEvent(string inputString) { try { //iterate through all factories. If one and only one of them accepts //the string, generate the event. Otherwise, throw an exception. return factories.Single(factory => factory.AcceptsInputString(inputString)).CreateEvent(inputString); } catch (InvalidOperationException e) { throw new InvalidOperationException("No valid factory found to generate this kind of Event!", e); } } } public class SportEvent1Factory : IEventFactory { public bool AcceptsInputString(string inputString) { return inputString.StartsWith("SportEvent1"); } public Event CreateEvent(string inputString) { return new SportEvent1(); } } public class MedicalEvent1Factory : IEventFactory { public bool AcceptsInputString(string inputString) { return inputString.StartsWith("MedicalEvent1"); } public Event CreateEvent(string inputString) { return new MedicalEvent1(); } } And here is the code that runs it: static void Main(string[] args) { EventFactory medicalEventFactory = new EventFactory(); medicalEventFactory.AddFactory(new MedicalEvent1Factory()); medicalEventFactory.AddFactory(new MedicalEvent2Factory()); EventFactory sportsEventFactory = new EventFactory(); sportsEventFactory.AddFactory(new SportEvent1Factory()); sportsEventFactory.AddFactory(new SportEvent2Factory()); } I have a couple of questions: Instead of having to add factories here in the main method of my application, should I try to redesign my EventFactory class so it is an abstract factory? It'd be better if I had a way of not having to manually add EventFactories every time I want to use them. So I could just instantiate MedicalFactory and SportsFactory. Should I make a Factory of factories? Maybe that'd be over-engineering? As you have probably noticed, I am using a inputString string as argument to feed the factories. I have an application that lets the user create his own events but also to load/save them from text files. Later, I might want to add other kinds of files, XML, sql connections, whatever. The only way I can think of that would allow me to make this work is having an internal format (I choose a string, as it's easy to understand). How would you make this? I assume this is a recurrent situation, probably most of you know of any other more intelligent approach to this. I am then only looping in the EventFactory for all the factories in its list to check if any of them accepts the input string. If one does, then it asks it to generate the Event. If you find there is something wrong or awkward with the method I'm using to make this happen, I'd be happy to hear about different implementations. Thanks! PS: Although I don't show it in here, all the different kind of events have different properties, so I have to generate them with different arguments (SportEvent1 might have SportName and Duration properties, that have to be put in the inputString as argument).

  • Using Comparable to compare objects and sorting them in a TreeMap

    - by arjacsoh
    II cannot understand how should the natural ordering of class be "consistent with equals" when implementing the Comparable interface. I deteted a flaw in my program and therefore I deteced that in the documentantion of the interface Comparable. My problem is that although two Objects are considered as distinct on the base of equals method, the TreeMap structure treats them as equal and consequently does not accept the second insert. The sample code is: public class Car implements Comparable<Car> { int weight; String name; public Car(int w, String n) { weight=w; name=n; } public boolean equals(Object o){ if(o instanceof Car){ Car d = (Car)o; return ((d.name.equals(name)) && (d.weight==weight)); } return false; } public int hashCode(){ return weight/2 + 17; } public String toString(){ return "I am " +name+ " !!!"; } public int compareTo(Car d){ if(this.weight>d.weight) return 1; else if(this.weight<d.weight) return -1; else return 0; } /*public int compareTo(Car d){ return this.name.compareTo(d.name); }*/ } public static void main(String[] args) { Car d1 = new Car(100, "a"); Car d2 = new Car(110, "b"); Car d3 = new Car(110, "c"); Car d4 = new Car(100, "a"); Map<Car, Integer> m = new HashMap<Car, Integer>(); m.put(d1, 1); m.put(d2, 2); m.put(d3, 3); m.put(d4, 16); for(Map.Entry<Car, Integer> me : m.entrySet()) System.out.println(me.getKey().toString() + " " +me.getValue()); TreeMap<Car, Integer> tm = new TreeMap<Car, Integer>(m); System.out.println("After Sorting: "); for(Map.Entry<Car, Integer> me : tm.entrySet()) System.out.println(me.getKey().toString() + " " +me.getValue()); } The output is : I am a !!! 16 I am c !!! 3 I am b !!! 2 After Sorting: I am a !!! 16 I am c !!! 2 That is, that the object c has replaced (somewhat) object b. If I comment the original equals method and uncomment the second equals method, which compares the objects according name, the output is the expected: I am a !!! 16 I am c !!! 3 I am b !!! 2 After Sorting: I am a !!! 16 I am b !!! 2 I am c !!! 3 Why does it come around in this way and what should I alter in order to insert and sort different objects with some attributes of equal value in a TreeMap?

  • Foreign key not stored in child entity (one-to-many)

    - by Kamil Los
    Hi, I'm quite new to hibernate and have stumbled on this problem, which I can't find solution for. When persisting parent object (with one-to-many relationship with child), the foreign-key to this parent is not stored in child's table. My classes: Parent.java @javax.persistence.Table(name = "PARENT") @Entity public class PARENT { private Integer id; @javax.persistence.Column(name = "ID") @Id @GeneratedValue(strategy=GenerationType.AUTO) public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } private Collection<Child> children; @OneToMany(mappedBy = "parent", fetch = FetchType.EAGER, cascade = {CascadeType.ALL}) @Cascade({org.hibernate.annotations.CascadeType.ALL}) public Collection<Child> getChildren() { return children; } public void setChildren(Collection<Child> children) { this.children = children; } } Child.java @javax.persistence.Table(name = "CHILD") @Entity @IdClass(Child.ChildId.class) public class Child { private String childId1; @Id public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @Id public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } private Parent parent; @ManyToOne @javax.persistence.JoinColumn(name = "PARENT_ID", referencedColumnName = "ID") public Parent getParent() { return parent; } public void setParent(Operation parent) { this.parent = parent; } public static class ChildId implements Serializable { private String childId1; @javax.persistence.Column(name = "CHILD_ID1") public String getChildId1() { return childId1; } public void setChildId1(String childId1) { this.childId1 = childId1; } private String childId2; @javax.persistence.Column(name = "CHIILD_ID2") public String getChildId2() { return childId2; } public void setChildId2(String childId2) { this.childId2 = childId2; } public ChildId() { } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; ChildId that = (ChildId) o; if (childId1 != null ? !childId1.equals(that.childId1) : that.childId1 != null) return false; if (childId2 != null ? !childId2.equals(that.childId2) : that.childId2 != null) return false; return true; } @Override public int hashCode() { int result = childId1 != null ? childId1.hashCode() : 0; result = 31 * result + (childId2 != null ? childId2.hashCode() : 0); return result; } } } Test.java public class Test() { private ParentDao parentDao; public void setParentDao(ParentDao parentDao) { this.parentDao = parentDao; } private ChildDao childDao; public void setChildDao(ChildDao childDao) { this.childDao = parentDao; } test1() { Parent parent = new Parent(); Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); ArrayList<Child> children = new ArrayList<Child>(); children.add(child); parent.setChildren(children); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) } test2() { Parent parent = new Parent(); parent.setValue("value"); parentDao.save(parent); //calls hibernate's currentSession.saveOrUpdate(entity) Child child = new Child(); child.setChildId1("a"); child.setChildId2("b"); child.setParent(parent); childDao.save(); //calls hibernate's currentSession.saveOrUpdate(entity) } } When calling test1(), both entities get written to database, but field PARENT_ID in CHILD table stays empty. The only workaround I have so far is test2() - persisting parent first, and then the child. My goal is to persist parent and its children in one call to save() on Parent. Any ideas?

  • Running code when all threads are finished processing.

    - by rich97
    Quick note: Java and Android noob here, I'm open to you telling me I'm stupid (as long as you tell me why.) I have an android application which requires me start multiple threads originating from various classes and only advance to the next activity once all threads have done their job. I also want to add a "failsafe" timeout in case one the the threads takes too long (HTTP request taking too long or something.) I searched Stack Overflow and found a post saying that I should create a class to keep a running total of open threads and then use a timer to poll for when all the threads are completed. I think I've created a working class to do this for me, it's untested as of yet but has no errors showing in eclipse. Is this a correct implementation? Are there any APIs that I should be made aware of (such as classes in the Java or Android APIs that could be used in place of the abstract classes at the bottom of the class?) package com.dmp.geofix.libs; import java.util.ArrayList; import java.util.Iterator; import java.util.Timer; import java.util.TimerTask; public class ThreadMonitor { private Timer timer = null; private TimerTask timerTask = null; private OnSuccess onSuccess = null; private OnError onError = null; private static ArrayList<Thread> threads; private final int POLL_OPEN_THREADS = 100; private final int TIMEOUT = 10000; public ThreadMonitor() { timerTask = new PollThreadsTask(); } public ThreadMonitor(OnSuccess s) { timerTask = new PollThreadsTask(); onSuccess = s; } public ThreadMonitor(OnError e) { timerTask = new PollThreadsTask(); onError = e; } public ThreadMonitor(OnSuccess s, OnError e) { timerTask = new PollThreadsTask(); onSuccess = s; onError = e; } public void start() { Iterator<Thread> i = threads.iterator(); while (i.hasNext()) { i.next().start(); } timer = new Timer(); timer.schedule(timerTask, 0, POLL_OPEN_THREADS); } public void finish() { Iterator<Thread> i = threads.iterator(); while (i.hasNext()) { i.next().interrupt(); } threads.clear(); timer.cancel(); } public void addThread(Thread t) { threads.add(t); } public void removeThread(Thread t) { threads.remove(t); t.interrupt(); } class PollThreadsTask extends TimerTask { private int timeElapsed = 0; @Override public void run() { timeElapsed += POLL_OPEN_THREADS; if (timeElapsed <= TIMEOUT) { if (threads.isEmpty() == false) { if (onSuccess != null) { onSuccess.run(); } } } else { if (onError != null) { onError.run(); } finish(); } } } public abstract class OnSuccess { public abstract void run(); } public abstract class OnError { public abstract void run(); } }

  • How to determine edges in an images optimally?

    - by SorinA.
    I recently was put in front of the problem of cropping and resizing images. I needed to crop the 'main content' of an image for example if i had an image similar to this: the result should be an image with the msn content without the white margins(left& right). I search on the X axis for the first and last color change and on the Y axis the same thing. The problem is that traversing the image line by line takes a while..for an image that is 2000x1600px it takes up to 2 seconds to return the CropRect = x1,y1,x2,y2 data. I tried to make for each coordinate a traversal and stop on the first value found but it didn't work in all test cases..sometimes the returned data wasn't the expected one and the duration of the operations was similar.. Any idea how to cut down the traversal time and discovery of the rectangle round the 'main content'? public static CropRect EdgeDetection(Bitmap Image, float Threshold) { CropRect cropRectangle = new CropRect(); int lowestX = 0; int lowestY = 0; int largestX = 0; int largestY = 0; lowestX = Image.Width; lowestY = Image.Height; //find the lowest X bound; for (int y = 0; y < Image.Height - 1; ++y) { for (int x = 0; x < Image.Width - 1; ++x) { Color currentColor = Image.GetPixel(x, y); Color tempXcolor = Image.GetPixel(x + 1, y); Color tempYColor = Image.GetPixel(x, y + 1); if ((Math.Sqrt(((currentColor.R - tempXcolor.R) * (currentColor.R - tempXcolor.R)) + ((currentColor.G - tempXcolor.G) * (currentColor.G - tempXcolor.G)) + ((currentColor.B - tempXcolor.B) * (currentColor.B - tempXcolor.B))) > Threshold)) { if (lowestX > x) lowestX = x; if (largestX < x) largestX = x; } if ((Math.Sqrt(((currentColor.R - tempYColor.R) * (currentColor.R - tempYColor.R)) + ((currentColor.G - tempYColor.G) * (currentColor.G - tempYColor.G)) + ((currentColor.B - tempYColor.B) * (currentColor.B - tempYColor.B))) > Threshold)) { if (lowestY > y) lowestY = y; if (largestY < y) largestY = y; } } } if (lowestX < Image.Width / 4) cropRectangle.X = lowestX - 3 > 0 ? lowestX - 3 : 0; else cropRectangle.X = 0; if (lowestY < Image.Height / 4) cropRectangle.Y = lowestY - 3 > 0 ? lowestY - 3 : 0; else cropRectangle.Y = 0; cropRectangle.Width = largestX - lowestX + 8 > Image.Width ? Image.Width : largestX - lowestX + 8; cropRectangle.Height = largestY + 8 > Image.Height ? Image.Height - lowestY : largestY - lowestY + 8; return cropRectangle; } }

  • set different images to uitableview cell

    - by Sudha
    I am making an app in which one of the view has a tableview. Tableview cell has two conditions. There are two images which are going to be set on uitableview cell according to the condition i.e. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ NSString *que =[[userqueries objectAtIndex:indexPath.row]objectForKey:@"question"]; NSString *ans =[[userqueries objectAtIndex:indexPath.row]objectForKey:@"answer"]; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; cell.imageView.image=nil; if ((que.length!=0)&&(ans.length!=0)) { UIImageView* imag = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 75)]; imag.image = [UIImage imageNamed:@"ques.png"]; [cell.contentView addSubview:imag]; questext = [[UITextView alloc]initWithFrame:CGRectMake(10, 0, 300, 35)]; questext.backgroundColor = [UIColor clearColor]; questext.delegate = self; questext.tag = 101; questext.textAlignment = UITextAlignmentLeft; questext.editable = NO; questext.scrollEnabled = YES; [cell addSubview:questext]; anstext = [[UITextView alloc]initWithFrame:CGRectMake(10, 37, 300, 35)]; anstext.backgroundColor = [UIColor clearColor]; anstext.delegate = self; anstext.tag = 102; anstext.scrollEnabled = YES; anstext.textAlignment = UITextAlignmentLeft; anstext.editable = NO; [cell addSubview:anstext]; } else { UIImageView* imag = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 40)]; imag.image = [UIImage imageNamed:@"answ.png"]; [cell.contentView addSubview:imag]; onlyques = [[UITextView alloc]initWithFrame:CGRectMake(10, 0, 300, 35)]; onlyques.backgroundColor= [UIColor clearColor]; [onlyques setScrollEnabled:YES]; onlyques.delegate = self; onlyques.tag = 103; onlyques.textAlignment = UITextAlignmentLeft; onlyques.editable = NO; onlyques.scrollEnabled = YES; [cell addSubview:onlyques]; } } questext = (UITextView*)[cell viewWithTag:101]; questext.text = que; anstext = (UITextView*)[cell viewWithTag:102]; anstext.text = ans; onlyques = (UITextView*)[cell viewWithTag:103]; onlyques.text = que; return cell; } But image is not appearing properly. As I scroll up and down the table view ,images get changes automatically. Please look upon my code and help me in finding the error. second image is when I scroll up and down the table view and first image is in the starting. please help me. if any one knows how to load different images to uitableview cell. thanks in advance.

  • Listening for TCP and UDP requests on the same port

    - by user339328
    I am writing a Client/Server set of programs Depending on the operation requested by the client, I use make TCP or UDP request. Implementing the client side is straight-forward, since I can easily open connection with any protocol and send the request to the server-side. On the servers-side, on the other hand, I would like to listen both for UDP and TCP connections on the same port. Moreover, I like the the server to open new thread for each connection request. I have adopted the approach explained in: link text I have extended this code sample by creating new threads for each TCP/UDP request. This works correctly if I use TCP only, but it fails when I attempt to make UDP bindings. Please give me any suggestion how can I correct this. tnx Here is the Server Code: public class Server { public static void main(String args[]) { try { int port = 4444; if (args.length > 0) port = Integer.parseInt(args[0]); SocketAddress localport = new InetSocketAddress(port); // Create and bind a tcp channel to listen for connections on. ServerSocketChannel tcpserver = ServerSocketChannel.open(); tcpserver.socket().bind(localport); // Also create and bind a DatagramChannel to listen on. DatagramChannel udpserver = DatagramChannel.open(); udpserver.socket().bind(localport); // Specify non-blocking mode for both channels, since our // Selector object will be doing the blocking for us. tcpserver.configureBlocking(false); udpserver.configureBlocking(false); // The Selector object is what allows us to block while waiting // for activity on either of the two channels. Selector selector = Selector.open(); tcpserver.register(selector, SelectionKey.OP_ACCEPT); udpserver.register(selector, SelectionKey.OP_READ); System.out.println("Server Sterted on port: " + port + "!"); //Load Map Utils.LoadMap("mapa"); System.out.println("Server map ... LOADED!"); // Now loop forever, processing client connections while(true) { try { selector.select(); Set<SelectionKey> keys = selector.selectedKeys(); // Iterate through the Set of keys. for (Iterator<SelectionKey> i = keys.iterator(); i.hasNext();) { SelectionKey key = i.next(); i.remove(); Channel c = key.channel(); if (key.isAcceptable() && c == tcpserver) { new TCPThread(tcpserver.accept().socket()).start(); } else if (key.isReadable() && c == udpserver) { new UDPThread(udpserver.socket()).start(); } } } catch (Exception e) { e.printStackTrace(); } } } catch (Exception e) { e.printStackTrace(); System.err.println(e); System.exit(1); } } } The UDPThread code: public class UDPThread extends Thread { private DatagramSocket socket = null; public UDPThread(DatagramSocket socket) { super("UDPThread"); this.socket = socket; } @Override public void run() { byte[] buffer = new byte[2048]; try { DatagramPacket packet = new DatagramPacket(buffer, buffer.length); socket.receive(packet); String inputLine = new String(buffer); String outputLine = Utils.processCommand(inputLine.trim()); DatagramPacket reply = new DatagramPacket(outputLine.getBytes(), outputLine.getBytes().length, packet.getAddress(), packet.getPort()); socket.send(reply); } catch (IOException e) { e.printStackTrace(); } socket.close(); } } I receive: Exception in thread "UDPThread" java.nio.channels.IllegalBlockingModeException at sun.nio.ch.DatagramSocketAdaptor.receive(Unknown Source) at server.UDPThread.run(UDPThread.java:25) 10x

  • Why is parsing a jSON response to a jQUERY ajax request not working

    - by Ankur
    I know there are several similar questions on SO, I have used some of them to get this far. I am trying to list a set of urls that match my input values. I have a servlet which takes some input e.g. "aus" in the example below and returns some output using out.print() e.g. the two urls I have shown below. EXAMPLE Input: "aus" Output: [{"url":"http://dbpedia.org/resource/Stifel_Nicolaus"},{"url":"http://sempedia.org/ontology/object/Australia"}] Which is exactly what I want. I have seen that firebug doesn't seem to have anything in the response section despite having called out.print(jsonString); and it seems that out.print(jsonString); is working as expected which suggests that the variable 'jsonString' contains the expected values. However I am not exactly sure what is wrong. -------- The jQuery --------- $(document).ready(function() { $("#input").keyup(function() { var input = $("#input").val(); //$("#output").html(input); ajaxCall(input); }); }); function ajaxCall(input) { // alert(input); $.ajax({ url: "InstantSearchServlet", data: "property="+input, beforeSend: function(x) { if(x && x.overrideMimeType) { x.overrideMimeType("application/j-son;charset=UTF-8"); } }, dataType: "json", success: function(data) { for (var i = 0, len = datalength; i < len; ++i) { var urlData = data[i]; $("#output").html(urlData.url); } } }); } ------ The Servlet that calls the DAO class - and returns the results ------- public class InstantSearchServlet extends HttpServlet{ private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { System.out.println("You called?"); response.setContentType("application/json"); PrintWriter out = response.getWriter(); InstantSearch is = new InstantSearch(); String input = (String)request.getParameter("property"); System.out.println(input); try { ArrayList<String> urllist; urllist = is.getUrls(input); String jsonString = convertToJSON(urllist); out.print(jsonString); System.out.println(jsonString); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private String convertToJSON(ArrayList<String> urllist) { Iterator<String> itr = urllist.iterator(); JSONArray jArray = new JSONArray(); int i = 0; while (itr.hasNext()) { i++; JSONObject json = new JSONObject(); String url = itr.next(); try { json.put("url",url); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } jArray.put(json); } String results = jArray.toString(); return results; } }
