  • How can I hot deploy using the glassfish adapter in Eclipse

    - by Greg
    Has anyone gotten the glassfish v3 adapter to work with Eclipse without restarting every time there's a code change? I tried to set this up but the adapter "republishes" every time I change any file, which is very annoying. It takes up to 3 minutes and locks up my machine for a second. I must remember to constantly stop the adapter before making any changes. I'd settle for just disabling this "feature", but even if I uncheck "publish change immediately" this behavior still happens. I'm using the latest version of the glassfish adapter and tried with eclipse 3.5 and the 3.6 milestone builds.... What setup is everyone using if you have glassfish v3 as your server? Is there any way to actually get the hot deploy feature to work correctly?

  • Hibernate annotations cascading doesn't work

    - by user304309
    Hi all, I've decided to change hbm.xml style to annotations using hibernate. I had in my hbm.xml: <hibernate-mapping package="by.sokol.jpr.data"> <class name="Licence"> <id name="licenceId"> <generator class="native" /> </id> <many-to-one name="user" lazy="false" cascade="save-update" column="usr"/> </class> </hibernate-mapping> And changed it to: @Entity public class Licence { @Id @GeneratedValue(strategy = GenerationType.AUTO) private int licenceId; @ManyToOne(targetEntity=User.class, fetch=FetchType.EAGER, cascade = CascadeType.ALL) @Cascade(value = { org.hibernate.annotations.CascadeType.SAVE_UPDATE }) private User user; } And hibernate doesn't save user on saving. I really need help!

  • GWT: Best practice for unit testing / mocking JSNI methods?

    - by Epaga
    I have a class which uses JSNI to retrieve JSON data stored in the host page: protected native JsArray<JsonModel> getModels() /*-{ return $wnd.jsonData; }-*/; This method is called, and the data is then translated and process in a different method. How should I unit test this class, since I'm not able to instantiate (or seemingly mock?) JsArray? What is the best way to unit test JSNI methods at all?

  • Adding a Layout to bottom of the screen inside a ScrollView in Landscape mode

    - by andreea
    I have the following layout which works in Portrait mode: the Layout with the id LinearLayout02 is placed at the bottom of the screen. The problem appears when flipping to Lanscape mode, when the #LinearLayout02 is placed at the top of the screen. The question is how do I position #LinearLayout02 at the bottom of the screen in both Portrait and Landscape mode? (This happens on G1 and Xperia) Thank you The following code is placed inside a ScrollView android:layout_height="fill_parent" android:layout_width="fill_parent" android:fillViewport="true" <LinearLayout android:id="@+id/sLayout" android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="vertical" android:paddingTop="2dip" android:layout_alignParentTop="true" android:gravity="top" > ..... </LinearLayout> <LinearLayout android:id="@+id/LinearLayout02" android:background="@drawable/bottombar_bg" android:layout_width="fill_parent" android:paddingTop="10dip" android:layout_height="56dip" android:layout_alignParentBottom="true" android:gravity="bottom" > <Button android:id="@+id/navigate" style="@style/mainBottomTabsButtonNormal" android:drawableLeft="@drawable/icon_navigation" android:text="@string/navigationSettings" android:layout_gravity="left"> </Button> <Button android:id="@+id/search" style="@style/mainBottomTabsButtonActive" android:drawableLeft="@drawable/icon_search" android:text="@string/search.label" android:layout_gravity="right"> </Button> </LinearLayout> </RelativeLayout>

  • Using OpenSessionInViewInterceptor with Hibernate and JSF 2

    - by sammy
    I'm building an application in Hibernate, Spring and JSF2 using only annotations. How can I take advantage of OpenSessionInViewInterceptor found in Spring to catch any hibernate session that might open within a bean? I'm trying to elegantly solve the common “failed to lazily initialize a collection of role: your.Class.assocation no session or session was closed.” problem when trying to read from a yet uninitialized list of POJOs inside another POJO (A Tag entity retrieved by a DAO that contains a List of Project objects I want to read). I've found this: http://www.paulcodding.com/blog/2008/01/21/using-the-opensessioninviewinterceptor-for-spring-hibernate3/ but failed to make use of it in my environment. Please provide a detailed answer, as the Internet is full of foggy, unhelpful tutorials. I'll also be greatful for an alternative solution, given a step-by-step instruction is provided.

  • Generating a Call Hierarchy for dynamicly invoked method

    - by Maxim Veksler
    Hello, Today's world of dynamic invoke, reflection and runtime injection just doesn't play well with traditional tools such as ctags, doxygen and CDOC. I am searching for a method call hierarchy visualization tool that can display both static and dynamic method invocations. It should be easy to use, light during execution and provide helpful detailed information about the recorded runtime session. Now I guess Callgrind could be considered a valid solution for the family C. What tool / technique could you suggest to create a call graph for both static and dynamic method invocation for JVM based bytecode? The intended end result is a graphical display (preferably interactive) which can show path from main() to each method that was invoked. During research for this post I stumbled upon javashot, it seems that this is the kind of approach I'm aiming at, I would prefer that this would be integrated into a kind of profiler or alike which than can be used from within my IDE (Eclipse, IntelliJ, Netbeans and alike). Thank you, Maxim.

  • question about joGL (glTexImage2D)

    - by Nour
    Hi everybody I was trying to load a texture using joGL library but it seems that something is missing when using this method glTexImage2D at : IOStream wdis = new IOStream(fileName); wdis.skipBytes(18); int width = wdis.readIntW(); // dis.skipBytes(2); int height = wdis.readIntW(); // dis.skipBytes(2); wdis.skipBytes(28); byte buf[] = new byte[wdis.available()]; wdis.read(buf); wdis.close(); gl.glBindTexture(GL.GL_TEXTURE_2D, BMPtextures[index]); gl.glTexImage2D(GL.GL_TEXTURE_2D, 0, 3, width, height, 0, GL.GL_BGR, GL.GL_UNSIGNED_BYTE, buf); gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MAG_FILTER, GL.GL_LINEAR); gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MIN_FILTER, GL.GL_LINEAR); as IOStream is a class that extends DataInputStream it shows a message that glTexImage2D(int,int,int,int,int,int,int,int,byte[]) is not found at javax.media.opengl.GL I couldn't figure the problem her because it's an open source code and it seems to work perfectly with my friends but unfortunately not with me even though we are using the same library and the same JDK version what shall I do ??

  • ScrollView alawys scrolling to the bottom

    - by Sebi
    I defined a scrollview with a texteedit in my layout: <ScrollView android:fillViewport="true" android:layout_marginBottom="50dip" android:id="@+id/start_scroller" android:layout_height="fill_parent" android:layout_width="fill_parent" android:fadingEdge="none"> <TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content" > </TextView> </ScrollView> I add text to this ScrollView with the following method: public void writeToLogView(String textMsg) { if (text.getText().equals("")) { text.append(textMsg); } else { text.append("\n" + textMsg); scroller.scrollBy(0, 1000000); } } As you can see i append the text and try to scroll to the bottom of the ScrollView. Unfortunately this doesn't worked correctly. It scrolls down, but not always, and not always to the bottom. Any hints?

  • Iteration speed of int vs long

    - by jqno
    I have the following two programs: long startTime = System.currentTimeMillis(); for (int i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); and long startTime = System.currentTimeMillis(); for (long i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); Note: the only difference is the type of the loop variable (int and long). When I run this, the first program consistently prints between 0 and 16 msecs, regardless of the value of N. The second takes a lot longer. For N == Integer.MAX_VALUE, it runs in about 1800 msecs on my machine. The run time appears to be more or less linear in N. So why is this? I suppose the JIT-compiler optimizes the int loop to death. And for good reason, because obviously it doesn't do anything. But why doesn't it do so for the long loop as well? A colleague thought we might be measuring the JIT compiler doing its work in the long loop, but since the run time seems to be linear in N, this probably isn't the case.

  • adding only odd numbers

    - by Jessica M.
    So the question I'm trying to solve the user is supposed to enter any positive number. Then I'm trying to write a program that adds only the odd numbers up to the number the user enters and displays the total. So for example if the user enters 4 my program should add four odd numbers. 1 + 3 + 5 + 7 = 16. The only tools I have available are for statement, if, if/else if,while loop and println. I can only figure out how to print out the odd numbers. I know I want to create a variable named total to store the value of adding up all the odd numbers but I don't know how that fits into the program. import acm.program.*; public class AddingOddNumbers extends ConsoleProgram { public void run() { int n = readInt("enter a positive nunber: "); int total = 0; for (int i = 0; i < n; i++) { if (n == 1) { println(1); } else { println((i * 2) + 1); } } } }

  • Authenticating a single request with httpclient 4.x

    - by scompt.com
    I have an HttpClient instance that's shared by a number of threads. I would like to use it to make a single authenticated request. Because only the single request should be authenticated, I don't want to modify the HttpClient instance as described in the documentation. Here's what I've worked out instead, which isn't working. From what I can tell, it doesn't look like the CredentialsProvider is being used at all. Any tips? HttpContext context = null; if(feedSpec.isAuthenticated()) { context = new BasicHttpContext(); CredentialsProvider credsProvider = new BasicCredentialsProvider(); credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(feedSpec.getHttpUsername(), feedSpec.getHttpPassword())); context.setAttribute(ClientContext.CREDS_PROVIDER, credsProvider); context.setAttribute(ClientPNames.HANDLE_AUTHENTICATION, true); } HttpGet httpGet = new HttpGet(feedSpec.getUri()); HttpResponse httpResponse = httpClient.execute(httpGet, context);

  • Why does my Sax Parser produce no results after using InputStream Read?

    - by Andy Barlow
    Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

  • Xpages - Get number of active sessions

    - by Jairo
    How do I get the number of active sessions in Xpage. I'm trying to use managed beans but it just returns a weird string. Here's the simple code: import javax.servlet.http.HttpSessionEvent; import javax.servlet.http.HttpSessionListener; public class SessionCounterListener implements HttpSessionListener { private static int totalActiveSessions; public static int getTotalActiveSessions(){ return totalActiveSessions | 0; } public void sessionCreated(HttpSessionEvent arg0) { totalActiveSessions++; System.out.println("sessionCreated - add one session into counter"); } public void sessionDestroyed(HttpSessionEvent arg0) { totalActiveSessions--; System.out.println("sessionDestroyed - deduct one session from counter"); } } I got this from here. But when I call SessionCounterListener.getTotalActiveSessions(), it only returns a weird string, example com.gs3.beans.SessionCounterListener@46c446c4. Please help me. Thanks a lot!

  • JAXB: How to avoid repeated namespace definition for xmlns:xsi

    - by sfussenegger
    I have a JAXB setup where I use a @XmlJavaTypeAdapter to replace objects of type Person with objects of type PersonRef that only contains the person's UUID. This works perfectly fine. However, the generated XML redeclares the same namespace (xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance") every time it's used. While this is generally okay, it just doesn't feel right. How can I configure JAXB to declare xmlns:xsi at the very beginning of the document? Can I manually add namespace declarations to the root element? Here's an example of what I want to achive: Current: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <!-- SNIP: some more relations --> </person> Wanted: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"/> </relation> <!-- SNIP: some more relations --> </person>

  • How to get descriptive error messages from DB2?

    - by tangens
    When I call a SQL statement via JDBC on the DB2 and the statement fails, I catch an SQLException with the following message text: com.ibm.db2.jcc.a.nn: DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=O.METADATENSATZ, DRIVER=3.52.95 I tried an automatic translation of the message according to the error list published by IBM, but there are placeholders inside the messages referencing other elements of the exception. While looking for these elements inside the exception, I found the DB2ExceptionFormatter and tried to use it to access the missing elements. But here I stopped, because the DB2ExceptionFormatter gave me a clue: Error occurred while trying to obtain message text from server. Only message tokens are available. So my question is: What do I have to configure to get the correct messages from the DB2 server? If I can get a human readable message from the server, I could use it directly and wouldn't have to translate it by myself.

  • Blackberry Eclispe plugin and emulator

    - by gmcalab
    So I installed the following installation packages to develop Blackberry apps using the included emulators. I first installed them on a macbook pro, virtualizing windows 7 x86 with vmware. Everything worked fine, I created a quick HelloWorld app and it compiled and fully ran in the emulator. I did no other configuration. So I went to install this on my desktop PC with Windows 7 x64. I installed the exact same items. When I choose to run with the Blackberry Emulator, nothing happens. Any ideas? Here's the file list: BlackBerry_JDE_PluginFull_1.0.0.67 (This includes Eclispe) jdk-6u18-windows-i586

  • Websphere MQ using JMS, closed connections stuck on the MQ

    - by Ahmad
    I have a simple JMS application deployed on OC4J under AIX server, in my application I'm listening to some queues and sending to other queues on a Websphere MQ deployed under AS400 server. The problem is that my connections to these queues are terminated/closed when it stays idle for some time with the error MQJMS1016 (this is not the problem), and when that happens I attempt to recover the connection and it works, however, the old connection is stuck at the MQ and would not terminate until it is terminated manually. The recovery code goes as follows: public void recover() { cleanup(); init(); } public void cleanup(){ if (session != null) { try { session .close(); } catch (JMSException e) { } } if (connection != null) { try { connection.close(); } catch (JMSException e) { } } } public void init(){ // typical initialization of the connection, session and queue... }
