问题 I have a JNLP package for my application. Now I have the need to pass command line arguments to my application. How do I extend my JNLP file to list the command line arguments? For instance, I need to say java main.class arg1 arg2 and the arg1 and arg2 need to be mentioned as part of JNLP file. 回答1: Look to the description of the application-desc Element for further details of the argument element. The application element indicates that the JNLP file is launching an application (as opposed to

问题 We have a java app which uses Java Web Start. The jnlp file is configured with [j2se version="1.5+"]. So if JRE 1.5 and 1.6 are installed, the app is run on 1.6. Now, we have requirement where the app should be restricted to run only within the range - JRE 1.5.0_07 through JRE 1.5.0_17 [j2se version="1.5*"] will not work - it will always launch the app with the latest jre from 1.5 family. I can request an exact product version by including the href attribute. [j2se version="1.5.0_14" href=

问题 I am learning Java and trying to run some examples using Java web start. However, I cannot seem to find that package javax.jnlp . This same error is haunting me on both windows and linux.I've installed oracle jdk 7 on windows.OpenJDK 1.6 is the version installed on linux. Searching the internet for the package with no luck.It is no longer available on oracle's website because they insist that the package is a part of the jdk. I've searched the installation directories for it.some claim it is

问题 I created a Java desktop-application (using Swing) and am now trying to make it work by starting it from the net using JNLP. The application works fine when I start it from the terminal, but as soon as I launch it from JNLP, it does not close. I have to manually kill the process every time. I read that there might be a problem if my JFrame uses DISPOSE_ON_CLOSE as the default close-operation, but it doesn't. It uses DO_NOTHING_ON_CLOSE (implicitly). Also, I'm explicitly calling System.exit(0)

问题 I have a Java Web Start application, which I used to start through a shortcut: "C:\Program Files\Java\jdk1.7.0_67\bin\javaws.exe" -J-Dfile.encoding=UTF-8 -J-Xdebug -J-Xnoagent -J-Xrunjdwp:transport=dt_socket,server=n,suspend=y,address=8200" http://xxx/yyy/zzz.jnlp But after installing JDK 1.8 it all stopped working, my javaws don't see any of additional X||D params. I tried this way: setenv JAVAWS_VM_ARGS "-Dfile.encoding=UTF-8 -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=n,suspend

问题 We run the application from the attached JNLP. On the Java console, we have output the system properties with D. The properties from our JNLP files are not set any more. This is the first Java version that we get this sort of problems with. Everything was working fine up to and including 7 Update 40. We have all the jars signed but there are no security attributes in their manifests. <?xml version="1.0" encoding="UTF-8"?> <jnlp spec="1.0+" codebase="http://10.0.10.230/webstart/app" href=

问题 I am running Gnome on OpenSuse. As a result, my system look and feel is GTK+, which has numerous ugly problems (see some of them here). During development of my swing app, I can run the client from command line or IDE and specify VM parameter -Dswing.systemlaf=com.sun.javax.swing.plaf.metal.CrossPlatformLookAndFeel to make it look good. But I don't know how to force Java Webstart to use this VM parameter when I start the application through JNLP. edit: This has nothing to do with the

问题 I have an applet which was running 1/2 year ago. Now i needed to 'reactivate' it however for an unknown reason it is not working anymore. Here are the specs: JNLP based NG Applet Tomcat 7 JRE 1.7.0_25 Firefox 22 and Chrome 28 This is the error I get: MissingFieldException[ The following required field is missing from the launch file: <jnlp>] at com.sun.javaws.jnl.XMLFormat.parse(Unknown Source) at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source) at com.sun.javaws.jnl
