  • Oracle JDBC intermittent Connection Issue

    - by Lipska
    I am experiencing a very strange problem This is a very simple use of JDBC connecting to an Oracle database OS: Ubuntu Java Version: 1.5.0_16-b02 1.6.0_17-b04 Database: Oracle 11g Release 11.1.0.6.0 When I make use of the jar file JODBC14.jar it connects to the database everytime When I make use of the jar file JODBC5.jar it connects some times and other times it throws an error ( shown below) If I recompile with Java 6 and use JODBC6.jar I get the same results as JODBC5.jar I need specific features in JODB5.jar that are not available in JODBC14.jar Any ideas Error Connecting to oracle java.sql.SQLException: Io exception: Connection reset at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:74) at oracle.jdbc.driver.DatabaseError.newSQLException(DatabaseError.java:110) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:171) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:227) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:494) at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:411) at oracle.jdbc.driver.PhysicalConnection.(PhysicalConnection.java:490) at oracle.jdbc.driver.T4CConnection.(T4CConnection.java:202) at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:33) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:474) at java.sql.DriverManager.getConnection(DriverManager.java:525) at java.sql.DriverManager.getConnection(DriverManager.java:171) at TestConnect.main(TestConnect.java:13) Code Below is the code I am using import java.io.; import java.sql.; public class TestConnect { public static void main(String[] args) { try { System.out.println("Connecting to oracle"); Connection con=null; Class.forName("oracle.jdbc.driver.OracleDriver"); con=DriverManager.getConnection( "jdbc:oracle:thin:@172.16.48.100:1535:sample", "JOHN", "90009000"); System.out.println("Connected to oracle"); con.close(); System.out.println("Goodbye"); } catch(Exception e){e.printStackTrace();} } }

  • An alternative to reading input from Java's System.in

    - by dvanaria
    I’m working on the UVa Online Judge problem set archive as a way to practice Java, and as a way to practice data structures and algorithms in general. They give an example input file to submit to the online judge to use as a starting point (it’s the solution to problem 100). Input from the standard input stream (java.lang.System.in) is required as part of any solution on this site, but I can’t understand the implementation of reading from System.in they give in their example solution. It’s true that the input file could consist of any variation of integers, strings, etc, but every solution program requires reading basic lines of text input from System.in, one line at a time. There has to be a better (simpler and more robust) method of gathering data from the standard input stream in Java than this: public static String readLn(int maxLg) { byte lin[] = new byte[maxLg]; int lg = 0, car = -1; String line = “”; try { while (lg < maxLg) { car = System.in.read(); if ((car < 0) || (car == ‘\n’)) { break; } lin[lg++] += car; } } catch (java.io.IOException e) { return (null); } if ((car < 0) && (lg == 0)) { return (null); // eof } return (new String(lin, 0, lg)); } I’m really surprised by this. It looks like something pulled directly from K&R’s “C Programming Language” (a great book regardless), minus the access level modifer and exception handling, etc. Even though I understand the implementation, it just seems like it was written by a C programmer and bypasses most of Java’s object oriented nature. Isn’t there a better way to do this, using the StringTokenizer class or maybe using the split method of String or the java.util.regex package instead?

  • Implementing a customized drawable in Android

    - by Girish
    Hi , I was trying to get hold of 2D graphics in Android. As a example i want to implement a custom drawable and show it in my Activity I have defined a customized drawable by extending from Android drawable as mentioned below myDrawable extends Drawable { private static final String TAG = myDrawable.class.getSimpleName(); private ColorFilter cf; @Override public void draw(Canvas canvas) { //First you define a colour for the outline of your rectangle Paint rectanglePaint = new Paint(); rectanglePaint.setARGB(255, 255, 0, 0); rectanglePaint.setStrokeWidth(2); rectanglePaint.setStyle(Style.FILL); //Then create yourself a Rectangle RectF rectangle = new RectF(15.0f, 50.0f, 55.0f, 75.0f); //in pixels Log.d(TAG,"On Draw method"); // TODO Auto-generated method stub Paint paintHandl = new Paint(); // paintHandl.setColor(0xaabbcc); paintHandl.setARGB(125, 234, 213, 34 ); RectF rectObj = new RectF(5,5,25,25); canvas.drawRoundRect(rectangle, 0.5f, 0.5f, rectanglePaint); } @Override public int getOpacity() { // TODO Auto-generated method stub return 100; } @Override public void setAlpha(int alpha) { // TODO Auto-generated method stub } @Override public void setColorFilter(ColorFilter cf) { // TODO Auto-generated method stub this.cf = cf; } } I am trying to get this displayed in my activity, as shown below public class custDrawable extends Activity { /** Called when the activity is first created. */ LinearLayout layObj = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); layObj = (LinearLayout) findViewById(R.id.parentLay); ImageView imageView = (ImageView) findViewById(R.id.icon2); myDrawable myDrawObj = new myDrawable(); imageView.setImageDrawable(myDrawObj); imageView.invalidate(); // layObj.addView(myDrawObj, params); } } But when i run the app i see no rectangle on the activity, can anyone help me out? Where am i going wrong?

  • What purpose does “using” serve when used the following way

    - by user287745
    What purpose does “using” serve when used the following way:- ONE EXAMPLE IS THIS, (AN ANSWERER- @richj - USED THIS CODE TO SOLVE A PROBLEM THANKS) private Method(SqlConnection connection) { using (SqlTransaction transaction = connection.BeginTransaction()) { try { // Use the connection here .... transaction.Commit(); } catch { transaction.Rollback(); throw; } } } OTHER EXAMPLE I FOUND WHILE READING ON MICROSOFT SUPPORT SITE public static void ShowSqlException(string connectionString) { string queryString = "EXECUTE NonExistantStoredProcedure"; StringBuilder errorMessages = new StringBuilder(); using (SqlConnection connection = new SqlConnection(connectionString)) { SqlCommand command = new SqlCommand(queryString, connection); try { command.Connection.Open(); command.ExecuteNonQuery(); } catch (SqlException ex) { for (int i = 0; i < ex.Errors.Count; i++) { errorMessages.Append("Index #" + i + "\n" + "Message: " + ex.Errors[i].Message + "\n" + "LineNumber: " + ex.Errors[i].LineNumber + "\n" + "Source: " + ex.Errors[i].Source + "\n" + "Procedure: " + ex.Errors[i].Procedure + "\n"); } Console.WriteLine(errorMessages.ToString()); } } } I AM doing at top of page as using system.data.sqlclient etc so why this using thing in middle of code, What if I omit it (I know the code will work) but what functionality will I be losing

  • JACOB (Java/COM/ActiveX) - How to troubleshoot event handling?

    - by Youval Bronicki
    I'm trying to use JACOB to interact with a COM object. I was able to invoke an initialization method on the object (and to get its properties), but am not getting any events back. The code is quoted below. I have a sample HTML+Javascript page (running in IE) that successfully receives events from the same object. I'm considering the following options, but would appreciate any concrete troubleshooting ideas ... Send my Java program to the team who developed the COM object, and have them look for anything suspicious on their side (does the object have a way on knowing whether there's a client listening to its events, and whether they were successfully delivered?) Get into the native parts of JACOB and try to debug on that side. That's a little scary given that my C++ is rusty and that I've never programmed for Windows. public static void main(String[] args) { try { ActiveXComponent c = new ActiveXComponent( "CLSID:{********-****-****-****-************}"); // My object's clsid if (c != null) { System.out.println("Version:"+c.getProperty("Version")); InvocationProxy proxy = new InvocationProxy() { @Override public Variant invoke(String methodName, Variant[] targetParameters) { System.out.println("*** Event ***: " + methodName); return null; } }; DispatchEvents de = new DispatchEvents((Dispatch) c.getObject(), proxy); c.invoke("Init", new Variant[] { new Variant(10), //param1 new Variant(2), //param2 }); System.out.println("Wating for events ..."); Thread.sleep(60000); // 60 seconds is long enough System.out.println("Cleaning up ..."); c.safeRelease(); } } catch (Exception e) { e.printStackTrace(); } finally { ComThread.Release(); } }

  • Graphviz or Dynagraph for Graph-manipulation Program?

    - by noahlavine
    I'm looking into writing a program that will show a graph to the user. The graph will change over time (the user should be able to right-click on a graph item and ask for more detail, which will pop out new bits of the graph), and the user might be able to drag parts of the graph around. I would ideally also like to be able to specify the relative layout of certain parts of the graph myself while leaving the overall layout up to a library, but that's not essential. I'm trying to decide on a graph layout library to use. As far as I can tell, the two leading candidates are Graphviz and Dynagraph. The Dynagraph website suggests that Graphviz is for drawing static graphs, and that Dynagraph was forked from Graphviz and contains algorithms for graphs that will be updated. It has a sample program called Dynasty that does exactly what I want. However, the Graphviz site contains an example program called Lefty which seems to do exactly what I want. Graphviz also seems to be much more widely used, judging by Google (and SO) results. Finally, I'd like to code the GUI part in a language like Python or Scheme, which makes me a bit hesitant to use C++ because I understand it's harder to interface that to interpreters. So my question is, which library is better for what I'm trying to do? Do they both have strong and weak points? Has one of them actually ceased development and is just leaving its website up to confuse me? (I've seen http://stackoverflow.com/questions/464000/simple-dynamic-graph-display-for-c and http://stackoverflow.com/questions/2376987/open-source-libraries-to-design-directed-graphs, but I can't tell whether they're right about the Graphviz or Dynagraph choice because of Lefty and also the language issue.)

  • iis7 compress dynamic content from custom handler

    - by Malloc
    I am having trouble getting dynamic content coming from a custom handler to be compressed by IIS 7. Our handler spits out json data (Content-Type: application/json; charset=utf-8) and responds to url that looks like: domain.com/example.mal/OperationName?Param1=Val1&Param2=Val2 In IIS 6, all we had to do was put the edit the MetaBase.xml and in the IIsCompressionScheme element make sure that the HcScriptFileExtensions attribute had the custom extension 'mal' included in it. Static and Dynamic compression is turned out at the server and website level. I can confirm that normal .aspx pages are compressed correctly. The only content I cannot have compressed is the content coming from the custom handler. I have tried the following configs with no success: <handlers> <add name="MyJsonService" verb="GET,POST" path="*.mal" type="Library.Web.HttpHandlers.MyJsonServiceHandlerFactory, Library.Web" /> </handlers> <httpCompression> <dynamicTypes> <add mimeType="application/json" enabled="true" /> </dynamicTypes> </httpCompression> _ <httpCompression> <dynamicTypes> <add mimeType="application/*" enabled="true" /> </dynamicTypes> </httpCompression> _ <staticContent> <mimeMap fileExtension=".mal" mimeType="application/json" /> </staticContent> <httpCompression> <dynamicTypes> <add mimeType="application/*" enabled="true" /> </dynamicTypes> </httpCompression> Thanks in advance for the help.

  • Call private methods and private properties from outside a class in PHP

    - by Pablo López Torres
    I want to access private methods and variables from outside the classes in very rare specific cases. I've seen that this is not be possible although introspection is used. The specific case is the next one: I would like to have something like this: class Console { final public static function run() { while (TRUE != FALSE) { echo "\n> "; $command = trim(fgets(STDIN)); switch ($command) { case 'exit': case 'q': case 'quit': echo "OK+\n"; return; default: ob_start(); eval($command); $out = ob_get_contents(); ob_end_clean(); print("Command: $command"); print("Output:\n$out"); break; } } } } This method should be able to be injected in the code like this: Class Demo { private $a; final public function myMethod() { // some code Console::run(); // some other code } final public function myPublicMethod() { return "I can run through eval()"; } private function myPrivateMethod() { return "I cannot run through eval()"; } } (this is just one simplification. the real one goes through a socket, and implement a bunch of more things...) So... If you instantiate the class Demo and you call $demo-myMethod(), you'll get a console: that console can access the first method writing a command like: > $this->myPublicMethod(); But you cannot run successfully the second one: > $this->myPrivateMethod(); Do any of you have any idea, or if there is any library for PHP that allows you to do this? Thanks a lot!

The problem I'm having with the current logic is that once Django authenticates a teacher user he has access to all teachers profiles basically by typing the teachers username in the url. Once a teacher finds a co-worker's username he has direct access to his data. Any suggestions would be much appreciated.

But now when I use VC++ 2008, I am getting error of exception handling. So is there any idea on how to use gettimeofday or something equivalent? Thanks for your reply and any help would be very appreciated:

  • Jersey / ServletContext and resource loading on startup.

    - by Raphael Jolivet
    Hello, I'm kind of new in web development with Java. I am developing a web service and I've chosen REST / Jersey for it. I want to init some stuff on startup of the service and to keep them all along the life of the service. First question : Is the constructor of the Jersey Servlet a good place to do that ? Basically, what I want to do is to load a config.ini file located in my WEB-INF directory. Following this help, I understand I need a ServletContext to load my file as a resource. However, it is not clear to me how to get this ServletContext in a Jersey Servlet, as it is not really an instance of a servlet, but rather a POJO with some annotations. I wanted to try this tip, but the attribute "context" is null in the constructor. I think that Jersey might populate it after the constructor. Right ? So how is the right way to do this ? Here is my code so far : /** Main REST servlet */ @Path("/") public class Servlet { // ---------------------------------------------------- // Constants // ---------------------------------------------------- static private final String CONFIG_PATH = "/WEB-INF/config.ini"; // ---------------------------------------------------- // Attributes // ---------------------------------------------------- /** Context */ @Context ServletContext context; // ---------------------------------------------------- // Constructor // ---------------------------------------------------- /** Init the servlet */ public Servlet() { // Load config.ini from WEB-INF Config.config = new Config( this.context.getResourceAsStream(CONFIG_PATH)); // FAIL! this.context is null ... } // ---------------------------------------------------- // URI Handlers // ---------------------------------------------------- /** Welcome page */ @GET @Path("/") @Produces(MediaType.TEXT_HTML) public String welcome() { return "<h1>Hi there.</h1>"; } } Any help would be much appreciated. Thanks in advance, Raphael

  • Different users get the same value in .ASPXANONYMOUS

    - by Malcolm Frexner
    My site allows anonymous users. I saw that under heavy load user get sometimes profile values from other users. This happens for anonymous users. I logged the access to profile data: /// <summary> /// /// </summary> /// <param name="controller"></param> /// <returns></returns> public static string ProfileID(this Controller controller ) { if (ApplicationConfiguration.LogProfileAccess) { StringBuilder sb = new StringBuilder(); (from header in controller.Request.Headers.ToPairs() select string.Concat(header.Key, ":", header.Value, ";")).ToList().ForEach(x => sb.Append(x)); string log = string.Format("ip:{0} url:{1} IsAuthenticated:{2} Name:{3} AnonId:{4} header:{5}", controller.Request.UserHostAddress, controller.Request.Url.ToString(), controller.Request.IsAuthenticated, controller.User.Identity.Name, controller.Request.AnonymousID, sb); _log.Debug(log); } return controller.Request.IsAuthenticated ? controller.User.Identity.Name : controller.Request.AnonymousID; } I can see in the log that user realy get the same cookievalue for .ASPXANONYMOUS even if they have different IP. Just to be safe I removed dependency injection for the FormsAuthentication. I dont use OutputCaching. My web.config has this setting for authentication: <anonymousIdentification enabled="true" cookieless="UseCookies" cookieName=".ASPXANONYMOUS" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" /> <authentication mode="Forms"> <forms loginUrl="~/de/Account/Login" /> </authentication> Does anybody have an idea what else I could log or what I should have a look at?

  • which xml validator will work perfectly for multithreading project

    - by Sunil Kumar Sahoo
    Hi All, I have used jdom for xml validation against schema. The main problem there is that it gives an error FWK005 parse may not be called while parsing The main reason was that multiple of threads working for xerces validation at the same time. SO I got the solution that i have to lock that validation. which is not good So I want to know which xml validator works perfectly for multithreading project public static HashMap validate(String xmlString, Validator validator) { HashMap<String, String> map = new HashMap<String, String>(); long t1 = System.currentTimeMillis(); DocumentBuilder builder = null; try { //obtain lock to proceed // lock.lock(); try { builder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); // Source source = new DOMSource(builder.parse(new ByteArrayInputStream(xmlString.getBytes()))); validator.validate(new StreamSource(new StringReader(xmlString))); map.put("ISVALID", "TRUE"); logger.info("We have successfuly validated the schema"); } catch (Exception ioe) { ioe.printStackTrace(); logger.error("NOT2 VALID STRING IS :" + xmlString); map.put("MSG", ioe.getMessage()); // logger.error("IOException while validating the input XML", ioe); } logger.info(map); long t2 = System.currentTimeMillis(); logger.info("XML VALIDATION TOOK:::" + (t2 - t1)); } catch (Exception e) { logger.error(e); } finally { //release lock // lock.unlock(); builder = null; } return map; } Thanks Sunil Kumar Sahoo

  • Is it a good practice to suppress warnings?

    - by Chris Cooper
    Sometimes while writing Java in Eclipse, I write code that generates warnings. A common one is this, which I get when extending the Exception class: public class NumberDivideException extends Exception { public NumberDivideException() { super("Illegal complex number operation!"); } public NumberDivideException(String s) { super(s); } } // end NumberDivideException The warning: The serializable class NumberDivideException does not declare a static final serialVersionUID field of type long. I know this warning is caused by my failure to... well, it says right above. I could solve it by including the serialVersionUID, but this is a one hour tiny assignment for school; I don't plan on serializing it anytime soon... The other option, of course, is to let Eclipse add @SuppressWarnings("serial"). But every time my mouse hovers over the Suppress option, I feel a little guilty. For programming in general, is it a good habit to suppress warnings? (Also, as a side question, is adding a "generated" serialVersionUID like serialVersionUID = -1049317663306637382L; the proper way to add a serialVersionUID, or do I have to determine the number some other way?)

  • Setting System.Drawing.Color through .NET COM Interop

    - by Maxim
    I am trying to use Aspose.Words library through COM Interop. There is one critical problem: I cannot set color. It is supposed to work by assigning to DocumentBuilder.Font.Color, but when I try to do it I get OLE error 0x80131509. My problem is pretty much like this one: http://bit.ly/cuvWfc update: Code Sample: from win32com.client import Dispatch Doc = Dispatch("Aspose.Words.Document") Builder = Dispatch("Aspose.Words.DocumentBuilder") Builder.Document = Doc print Builder.Font.Size print Builder.Font.Color Result: 12.0 Traceback (most recent call last): File "aaa.py", line 6, in <module> print Builder.Font.Color File "D:\Python26\lib\site-packages\win32com\client\dynamic.py", line 501, in __getattr__ ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1) pywintypes.com_error: (-2146233079, 'OLE error 0x80131509', None, None) Using something like Font.Color = 0xff0000 fails with same error message While this code works ok: using Aspose.Words; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Document doc = new Document(); DocumentBuilder builder = new DocumentBuilder(doc); builder.Font.Color = System.Drawing.Color.Blue; builder.Write("aaa"); doc.Save("c:\\1.doc"); } } } So it looks like COM Interop problem.

  • Doctrine stupid or me stupid?

    - by ropstah
    I want to use a single Doctrine install on our server and serve multiple websites. Naturally the models should be maintained in the websites' modelsfolder. I have everything up (and not running) like so: Doctrine @ /CustomFramework/Doctrine Websites @ /var/www/vhosts/custom1.com/ /var/www/vhosts/custom2.com/ Generating works fine, all models are delivered in /application_folder/models and /application_folder/models/generated for the correct website. I've added Doctrine::loadModels('path_to_models') in the bootstrap file for each website, and also registered the autoloaded. But.... This is the autoloader code: public static function autoload($className) { if (strpos($className, 'sfYaml') === 0) { require dirname(__FILE__) . '/Parser/sfYaml/' . $className . '.php'; return true; } if (0 !== stripos($className, 'Doctrine_') || class_exists($className, false) || interface_exists($className, false)) { return false; } $class = self::getPath() . DIRECTORY_SEPARATOR . str_replace('_', DIRECTORY_SEPARATOR, $className) . '.php'; if (file_exists($class)) { require $class; return true; } return false; } Am I stupid, or is the autoloader really doing this: $class = self::getPath() . DIRECTORY_SEPARATOR . str_replace('_', DIRECTORY_SEPARATOR, $className) . '.php'; or, in other words: Does it require me to have ALL my generated doctrine classes inside the Doctrine app directory? Or in other words, do I need a single Doctrine installation for each website? I'm getting an error that the BaseXXX class cannot be found. So the autoloading doesn't function correctly. I really hope i'm doing something wrong.. anyone?

  • Need help with creating PDF from HTML using itextsharp

    - by Steven
    I'm trying to crate a PDF out of a HTML page. The CMS I'm using is EPiServer. This is my code so far: protected void Button1_Click(object sender, EventArgs e) { naaflib.pdfDocument(CurrentPage); } public static void pdfDocument(PageData pd) { //Extract data from Page (pd). string intro = pd["MainIntro"].ToString(); // Attribute string mainBody = pd["MainBody"].ToString(); // Attribute // makae ready HttpContext HttpContext.Current.Response.Clear(); HttpContext.Current.Response.ContentType = "application/pdf"; // Create PDF document Document pdfDocument = new Document(PageSize.A4, 80, 50, 30, 65); //PdfWriter pw = PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream); PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream); pdfDocument.Open(); pdfDocument.Add(new Paragraph(pd.PageName)); pdfDocument.Add(new Paragraph(intro)); pdfDocument.Add(new Paragraph(mainBody)); pdfDocument.Close(); HttpContext.Current.Response.End(); } This outputs the content of the article name, intro-text and main body. But it does not pars HTML which is in the article text and there is no layout. I've tried having a look at http://itextsharp.sourceforge.net/tutorial/index.html without becomming any wiser. Any pointers to the right direction is greatly appreciated :)

  • Getting a binary file from resource in C#

    - by Jesse Knott
    Hello, I am having a bit of a problem, I am trying to get a PDF as a resource in my application. At this point I have a fillable PDF that I have been able to store as a file next to the binary, but now I am trying to embed the PDF as a resource in the binary. byte[] buffer; try { s = typeof(BattleTracker).Assembly.GetManifestResourceStream("libReports.Resources.DAForm1594.pdf"); buffer = new byte[s.Length]; int read = 0; do { read = s.Read(buffer, read, 32768); } while (read > 0); } catch (Exception e) { throw new Exception("Error: could not import report:", e); } // read existing PDF document PdfReader r = new PdfReader( // optimize memory usage buffer, null ); Every time I run the code I get an error saying "Rebuild trailer not found. Original Error: PDF startxref not found" When I was just opening the file via a path to the static file in my directory it worked fine. I have tried using different encodings UTF-8, UTF-32, UTF-7, ASCII, etc etc.... As a side note I had the same problem with getting a Powerpoint file as a resource, I was finally able to fix that problem by converting the Powerpoint to xml and using that. I have considered doing the same for the PDF but I am referencing elements by field name which does not seem to work with XML PDFs. Can anyone help me out with this? Thanks in advance!
