• Java (JSP): repeating the contentType header in a "sub-jsp"

  - by Webinator

  What happens when headers are repeated in a .jsp you include in another .jsp? For example if example.jsp starts with this: <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"> <jsp:directive.page contentType="text/html; charset=UTF-8" /> <div class="content"> <jsp:include page="support-header.jsp"/> ... (it includes support-header.jsp) And then support-header.jsp starts also with this: <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"> <jsp:directive.page contentType="text/html; charset=UTF-8" /> ... Is that a problem? Is it bad practice? What does concretely happen when you repeat several times a header that only corresponds to one header in the resulting .html page?

• Android ASync task ProgressDialog isn't showing until background thread finishes

  - by jackbot

  I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. My code is as follows: class AddTask extends AsyncTask<Void, Item, Void> { protected void onPreExecute() { pDialog = ProgressDialog.show(MyActivity.this,"Please wait...", "Retrieving data ...", true); } protected Void doInBackground(Void... unused) { items = parser.getItems(); for (Item it : items) { publishProgress(it); } return(null); } protected void onProgressUpdate(Item... item) { adapter.add(item[0]); } protected void onPostExecute(Void unused) { pDialog.dismiss(); } } Which I call in onCreate() with new AddTask().execute(); The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?

How to modify my code to have equal sized 4 areas on the screen like ? ?

• Implementing a listview inside a sliding drawer with a listview already present

  - by Parker

  I have an app whose main class extends ListActivity: public class GUIPrototype extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Cursor c = managedQuery(People.CONTENT_URI, null, null, null, null); String[] from = new String[] {People.NAME}; int[] to = new int[] { R.id.row_entry }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.drawer,c,from,to); setListAdapter(adapter); getListView().setTextFilterEnabled(true); } } I have a sliding drawer included in my XML, and I'm trying to get a separate listview to appear in the sliding drawer. I'm trying to populate the second listview using an inflater: View inflatedView = View.inflate(this, R.layout.main, null); ListView namesLV = (ListView) inflatedView.findViewById(R.id.content); String[] names2 = new String[] { "CS 345", "New Tag", "Untagged" }; ArrayAdapter<String> bb = new ArrayAdapter<String>(this, R.layout.main, R.id.row_entry, names2); namesLV.setAdapter(bb); This compiles, and runs, but the slidingdrawer is completely blank. My XML follows: <SlidingDrawer android:id="@+id/drawer" android:handle="@+id/handle" android:content="@+id/content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_gravity="bottom"> <ImageView android:id="@id/handle" android:layout_width="48px" android:layout_height="48px" android:background="@drawable/icon"/> <ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@id/content"/> </SlidingDrawer> I feel like I'm missing a vital step. I haven't found any resources on my problem by Googling, so any help would be greatly appreciated.

• Import Eclipse Plugin

  - by Timo

  Hey everybody, I developed an Eclipse plugin (a view) using the plugin development version of Eclipse. I exported the plugin as a jar archive and now I would like import it in another version of Eclipse, but it doesn't recognize the plugin. This is my first plugin so I might have forgotten something obvious. I searched the internet for hours but didn't find anything. Does anybody know what else I have to do? Btw, the dependencies of my plugin are: org.eclipse.ui, org.eclipse.core.runtime, org.eclipse.core.filesystem, edu.tum.cs.eclipse.commons, org.eclipse.ui.ide, org.eclipse.core.resources The version I'd like to import it in is the default Eclipse for PHP Developers from eclipse.org. The feature list can be found on http://www.eclipse.org/downloads/packages/eclipse-php-developers/galileosr2 Thanks for you help!

• How do you set tab view to scroll?

  - by DrogoNevets

  I have managed to set up a tabbed view for my app (woo!) and have the following xml for the UI <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="wrap_content"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout> <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Spinner android:id="@+id/areaSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <Spinner android:id="@+id/cragSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <Spinner android:id="@+id/routeSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <DatePicker android:id="@+id/dateClimbed" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <Spinner android:id="@+id/styleSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <Spinner android:id="@+id/detailsSpinner" android:layout_width="fill_parent" android:layout_height="@dimen/one_row" /> <TextView android:id="@+id/climbNotes" android:layout_width="fill_parent" android:layout_height="@dimen/three_row" /> </LinearLayout> yet am seemingly unable to scroll down to see the rest of the form (cuts off at one of the spinners, why is this? and how do i fix it?

• Grails, app-engine, jpa - TargetInvocationException

  - by John

  I'm trying to learn about grails with Google App Engine and JPA by following a few tutorials: http://www.morkeleb.com/2009/08/12/grails-and-google-appengine-beginners-guide/ http://inhouse32.appspot.com/index.html http://grails.org/plugin/app-engine I've got grails 1.3.0 RC 2, and App Engine SDK 1.3.3, and I'm using Windows 7.

• Android's EditText is hidden when the virtual keyboard is shown and a SurfaceView is involved

  - by Jan

  I have a simple user interface: an EditText should be located below a SurfaceView. I use a RelativeLayout to arrange these two views. Now, when I tap on the EditText to open the virtual keyboard the SurfaceView slides up but the EditText is hidden and does not show the typed string. To reproduce, use the following layout XML code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout01" android:layout_height="fill_parent" android:layout_width="fill_parent"> <SurfaceView android:id="@+id/SurfaceView01" android:layout_width="fill_parent" android:layout_height="wrap_content"> </SurfaceView> <EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" android:selectAllOnFocus="true" android:textStyle="normal" android:singleLine="true"> </EditText> </RelativeLayout> The main Activity class only needs to show the layout. When I start the program and tap the EditText, the virtual keyboard appears but the EditText field is gone. Maybe the RelativeLayout is causing the problems, but I don't know how to reproduce the same layout with another Layout class. Any suggestions are welcome, I really appreciate your help. Thanks. Edit: Here are two screenshots, one showing the EditText at the bottom without virtual keyboard, one with virtual keyboard but with no EditText. It is interesting to note that the SurfaceView and the EditText actually shift upward, the EditText just disappears. BTW this also happens to a button if it is next to the EditText. EditText below a SurfaceView (left); EditText is gone (right)

• How to populate Java (web) application with initial data using Spring/JPA/Hibernate

  - by Tuukka Mustonen

  I want to setup my database with initial data programmatically. I want to populate my database for development runs, not for testing runs (it's easy). The product is built on top of Spring and JPA/Hibernate. Developer checks out the project Developer runs command/script to setup database with initial data Developer starts application (server) and begins developing/testing then: Developer runs command/script to flush the database and set it up with new initial data because database structures or the initial data bundle were changed What I want is to setup my environment by required parts in order to call my DAOs and insert new objects into database. I do not want to create initial data sets in raw SQL, XML, take dumps of database or whatever. I want to programmatically create objects and persist them in database as I would in normal application logic. One way to accomplish this would be to start up my application normally and run a special servlet that does the initialization. But is that really the way to go? I would love to execute the initial data setup as Maven task and I don't know how to do that if I take the servlet approach. There is somewhat similar question. I took a quick glance at the suggested DBUnit and Unitils. But they seem to be heavily focused in setting up testing environments, which is not what I want here. DBUnit does initial data population, but only using xml/csv fixtures, which is not what I'm after here. Then, Maven has SQL plugin, but I don't want to handle raw SQL. Maven also has Hibernate plugin, but it seems to help only in Hibernate configuration and table schema creation (not in populating db with data). How to do this?

• WCF Web Service Gives 404 error in Azure

  - by landyman

  I'm new to using WCF and Azure, but I have a WCF Web Service that works correctly when debugging in Visual Studio. I set the startup project to Azure, and I get 404 errors for any URL I try related to the service. Here is what I think is relavant code: From IWebService.cs [OperationContract] [WebGet(UriTemplate = "GetData/Xml?value={value}", ResponseFormat=WebMessageFormat.Xml)] string GetDataXml(string value); and from Web.config: <system.serviceModel> <services> <service name="WebService" behaviorConfiguration="WebServiceBehavior"> <!-- Service Endpoints --> <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="WebEndpointBehavior"></endpoint> <endpoint address="ws" binding="wsHttpBinding" contract="IWebService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WebServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebEndpointBehavior"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> I have tried changing the binding to 'basicHttpBinding', but that had no luck. Thanks in advance for any help!

• Uncompress GZIPed HTTP Response in Java

  - by bill0ute

  Hi, I'm trying to uncompress a GZIPed HTTP Response by using GZIPInputStream. However I always have the same exception when I try to read the stream : java.util.zip.ZipException: invalid bit length repeat My HTTP Request Header: GET www.myurl.com HTTP/1.0\r\n User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; fr; rv:1.9.2) Gecko/20100115 Firefox/3.6\r\n Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n Accept-Language: fr,fr-fr;q=0.8,en-us;q=0.5,en;q=0.3\r\n Accept-Encoding: gzip,deflate\r\n Accept-Charset: ISO-8859-1,UTF-8;q=0.7,*;q=0.7\r\n Keep-Alive: 115\r\n Connection: keep-alive\r\n X-Requested-With: XMLHttpRequest\r\n Cookie: Some Cookies\r\n\r\n At the end of the HTTP Response header, I get path=/Content-Encoding: gzip, followed by the gziped response. I tried 2 similars codes to uncompress : GZIPInputStream gzip = new GZIPInputStream (new ByteArrayInputStream (tBytes)); StringBuffer szBuffer = new StringBuffer (); byte tByte [] = new byte [1024]; while (true) { int iLength = gzip.read (tByte, 0, 1024); // <-- Error comes here if (iLength < 0) break; szBuffer.append (new String (tByte, 0, iLength)); } And this one that I get on this forum : InputStream gzipStream = new GZIPInputStream (new ByteArrayInputStream (tBytes)); Reader decoder = new InputStreamReader (gzipStream, "UTF-8");//<- I tried ISO-8859-1 and get the same exception BufferedReader buffered = new BufferedReader (decoder); I guess this is an encoding error.

• WCF service The maximum array length quota (16384) has been exceeded

  - by dmitry.baranovsky

  I have a wsf service and a client application. While trying to communicate the client and the service I've gotten the following message: "The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:blob. The InnerException message was 'There was an error deserializing the object of type FileBlob. The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 25931.'. Please see InnerException for more details." I have the customBinding element and it doesn't allow me to insert "readerQuotas" section. In both the client and service configs I have the following binding element: <customBinding> <binding name="LicenseServiceBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"> <security authenticationMode="UserNameOverTransport"> <localClientSettings maxClockSkew="00:07:00" /> <localServiceSettings maxClockSkew="00:07:00" /> </security> <windowsStreamSecurity /> <httpsTransport maxReceivedMessageSize="2147483646"/> </binding> </customBinding> Thanks in advance for any help:)

• Getting MSDeploy working on our build/integration server - Is an MSBuild upgrade necessary?

  - by Jeff D

  We have what I think is a fairly standard build process: 1. Developer: Check in code 2. Build: Polls repo, sees change, and kicks off build that: 3. Build: Updates from repo, Builds w/ MSBuild, Runs unit tests w/ nunit, 4. Build: creates installer package Our security team allows us to pull from the build server, but does not allow the build server to push. So we generally rdp in, d/l the installers, and run them, which rules out the slick deployment services, so I would need to generate packages instead. I'd like to use MSDeploy, except that we have the following issues: We're on .net 3.5, and the MSBuild target (Package) that uses MSDeploy requires 4.0. Is there anything I'd need to install other than .net 4.0 RC for this? (Would MSBuild be part of that upgrade?) When I generate packages with MSDeploy, I see that I don't have just 1 file. There's a zip, deploy.cmd, SourceManifest.xml, and SetParameters.xml. What are all the other files for, and why wouldn't they all be in the 'package'? It sounds as if you can create packages by telling the system to look at a working IIS site. But if the packages are build from a CI environment, aren't you basically out of luck here? It feels like they designed some of this for small-scale developers deploying from their dev environment. That's a fine use case, but I'm interested in see what everyone's enterprise-experience is with the tool Any suggestions?

• Loading Properties with Spring (via System Properties)

  - by gabe

  My problem is as follows: I have server.properties for different environments. The path to those properties is provided trough a system property called propertyPath. How can I instruct my applicationContext.xml to load the properties with the given propertyPath system property without some ugly MethodInvokingBean which calls System.getProperty(''); My applicationContext.xml <bean id="systemPropertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> <property name="placeholderPrefix" value="sys{"/> <property name="properties"> <props> <prop key="propertyPath">/default/path/to/server.properties</prop> </props> </property> </bean> <bean id="propertyResource" class="org.springframework.core.io.FileSystemResource" dependency-check="all" depends-on="systemPropertyConfigurer"> <constructor-arg value="sys{propertyPath}"/> </bean> <bean id="serviceProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="location" ref="propertyResource"/> </bean> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" ref="propertyResource"/> <property name="placeholderPrefix" value="prop{"/> <property name="ignoreUnresolvablePlaceholders" value="true"/> <property name="ignoreResourceNotFound" value="false"/> </bean> <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="prop{datasource.name}"/> </bean> with this configuration the propertyResource alsways complains about java.io.FileNotFoundException: sys{propertyPath} (The system cannot find the file specified) Any suggestions? ;-) Thanks gabe

• Using android.view.SurfaceView with a camera on part of the screen

  - by oneself

  Hi, I trying to put together an Android app that will take a picture and process it in some way. I'd like the layout to be similar to Google Goggles. Meaning, camera preview on the top, and some controls on the bottom using portrait orientation. I've built a first version using code sample from here. This works, but I want to add a button on the bottom. I've modified my main.xml to look as follows: <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="150dp" android:stretchColumns="1"> <TableRow> <android.view.SurfaceView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/preview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </TableRow> <Button android:id="@+id/snap" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Snap" /> <TableRow> </TableRow> </TableLayout> But when I run this code I get an exception: java.lang.RuntimeException: startPreview failed. When I replace the SurfaceView above with something else, e.g. a TextView, that it displays, but in landscape. How can I get a camera preview on part of the screen using portrait view? Thanks

• Guice and JSF 2

  - by digitaljoel

  I'm trying to use Guice to inject properties of a JSF managed bean. This is all running on Google App Engine (which may or may not be important) I've followed the instructions here: http://code.google.com/docreader/#p=google-guice&s=google-guice&t=GoogleAppEngine One problem is in the first step. I can't subclass the Servlet module and setup my servlet mappings there because Faces is handled by the javax.faces.webapp.FacesServlet which subclasses Servlet, not HttpServlet. So, I tried leaving my servlet configuration in the web.xml file and simply instantiating a new ServletModel() along with my business module when creating the injector in the context listener described in the second step. Having done all that, along with the web.xml configuration, my managed bean isn't getting any properties injected. The method is as follows @ManagedBean @ViewScoped public class ViewTables implements Serializable { private DataService<Table> service; @Inject public void setService( DataService<Table> service ) { this.service = service; } public List<Table> getTables() { return service.getAll(); } } So, I'm wondering if there is a trick to get Guice injecting into a JSF managed bean? I obviously can't use the constructor injection because JSF needs a no-arg constructor to create the bean.

• Multiple choice list with custom view?

  - by Po

  I've seen example com.example.android.apis.view.List11 from ApiDemos. In that example, each row takes the view android.R.simple_list_item_multiple_choice. Each such view has a TextView and a CheckBox. Now I want each view to have 2 TextView's and 1 CheckBox, somewhat similar to the List3 example. I tried creating a custom layout file row.xml like this: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <CheckBox android:id="@+id/checkbox" android:layout_alignParentRight="true" android:layout_width="wrap_content" android:layout_height="fill_parent" /> <TextView android:id="@+id/text_name" android:textSize="13px" android:textStyle="bold" android:layout_toLeftOf="@id/checkbox" android:layout_alignParentLeft="true" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/text_phone" android:textSize="9px" android:layout_toLeftOf="@id/checkbox" android:layout_below="@id/text_name" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </RelativeLayout> Then in Activity.onCreate(), I do like this: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Query the contacts mCursor = getContentResolver().query(Phones.CONTENT_URI, null, null, null, null); startManagingCursor(mCursor); ListAdapter adapter = new SimpleCursorAdapter(this, R.layout.row, mCursor, new String[] { Phones.NAME, Phones.NUMBER}, new int[] { R.id.text_name, R.id.text_phone }); setListAdapter(adapter); getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); } The result kind of looks like what I want, but it looks like the list doesn't know which item of it is selected. Also, I need to click exactly on the checkbox. In the List11 example, I only need to click on the item row. So what do I need to do to make a multiple choice list with my custom view for each row? Many thanks.
