java-web-start

I have a Java webstart application that requires Java 7+, so the JNLP has this line: <j2se version="1.7+" href="http://java.sun.com/products/autodl/j2se"/> This works on various Windows XP & Windows 7 machines (most of them also having Java 6 installed) but on one of them, webstart is launched with Java 6 and fails (wrong version of JRE). I found this post and checked the Java settings and they look fine: I have also tried changing the JNLP line to this but it still does not work: <j2se version="1.7+"/> Any ideas on how to let webstart know that the JRE 1.7 is there? Config: Windows 7, run as

I am using JavaScript in order to execute JNLP which in the end will execute my client. I am trying to pass parameters via JavaScript execution to the JNLP and having those parameters via JNLP inside my client. The JavaScript is executing this URL for instance: http://localhost:8080/MyJnlp.jnlp?login=14hhh765p&pass=ggyyktff Now my JNLP will try to get the parameters in the <application-desc name tag this way: <application-desc name="..." main-class="com.main.execute" > <argument>-nosplash</argument> <argument>-q</argument> <argument><%=request.getParameter("login")%></argument> <argument><%

i have the following JNLP file: <jnlp spec="1.0+" codebase="http://****:****" href="tcm2012.jnlp"> <information> <title>TCM 2012</title> <vendor>Drift og Performance, *** Servicecenter</vendor> <homepage href="http://******"/> <description/> </information> <security> <all-permissions/> </security> <resources> <j2se version="1.6+"/> <jar href="tcm2012.jar"/> </resources> <application-desc main-class="com.****.kundeservice.TCMApplication"/> </jnlp> Now when i try to run in from the web i get the following error: Found unsigned entry in resource With the following exepction com.sun.deploy.net

Summary for those who might not want to read that much: How do I do this: ? If we could pass ad-hoc command-line args to javaws, then javaws apps could be more like "1st class citizen" "ordinary application". E.g. we could pass filenames of files to be opened. I would like to know if there is a way to pass "ad-hoc" command line arguments to the javaws executable. I already know how to specify them in JNLP file: <application-desc main-class="org.example.ClassName"> <argument>... While this can be used for what i want to accomplish, i treat this as a workaround. I tried javaws http://example.org

I found a bug in an application that completely freezes the JVM. The produced stacktrace would provide valuable information for the developers and I would like to retrieve it from the Java console. When the JVM crashes, the console is frozen and I cannot copy the contained text anymore. Is there way to pipe the Java console directly to a file or some other means of accessing the console output of a Java application? Update: I forgot to mention, without changing the code. I am a manual tester. Update 2: This is under Windows XP and it's actually a web start application. Piping the output of

I need to pass argument to JNLP dynamically for which I tried using a servlet which extends JnlpDownloadServlet and then includes a jsp which has all the JNLP XML written into it. But when I invoke the downloaded JNLP I get BadFieldException . Servlet public class TestServlet extends JnlpDownloadServlet { public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException { HttpServletRequest request = (HttpServletRequest) req; res.setContentType("application/x-java-jnlp-file"); request.getRequestDispatcher("/jnlp.jsp").include(request, res); } jnlp.jsp Used for

I need to do a performance test for JNLP accessible application. I used WireShark and see that the jnlp generates only TCP traffic. I read all the post related with jnlp perf testing and I tried with Apache JMeter + UbikLoadPack Java Serialization plugin but jmeter does not capture the traffic. Is it my only option capture the TCP traffic and work with that ? Regards, Jaime If traffic is HTTP(s), as per documentation of UbikLoadPack bundle, You need to follow the instructions of paragraphs: 1/Add JMeter certificate authority to the cacerts file used by Java: See in documentation " Configuring

Where is the jar files cached for Java Web Start/JNLP applications? Pascal Thivent It depends... on your OS and virtual machine, e.g.: with a Sun JDK 1.5 and Windows XP: C:\Documents and Settings\userid\Application Data\Sun\Java\Deployment\cache\javaws\ with a Sun JDK 1.6 and Vista: C:\Users\userid\AppData\LocalLow\Sun\Java\Deployment\cache\6.0 with a Sun JDK 1.6 and GNU/Linux: /home/userid/.java/deployment/cache/6.0 with a Sun JDK 1.6 and Mac OS X: ~/Library/Caches/Java/cache/6.0/ With a Sun JDK 6, this can be configured through the Java Control Panel (Temporary Internet Files Settings in the
