问题 Is there a way to change working dir for JVM when running Java Webstart? When i use system.setProperties("user.dir", newDir) it sets it(system.getProperties() shows it does) but ignores it. Is this a limitation in Java Webstart to always use the working dir where i started the jnlp file? I am using all permissions in the jnlp file. Please help! EDIT: Whatever i do now, my webstart always uses user.dir to save files. Frustrating! 回答1: I've had this question in the past myself, but I've always

问题 All my application I make with NetBeans as a Java Web Start applications behave quite strangely. When I run them as a normal application, everything works. But when I compile them as java web start apps, they, after the java web start is done with loading, repeatedly ask server for libraries on the wrong place. It doesn't seem to matter in small projects, but it makes a huge time difference in large projects (see my first question). I put a simple NetBeans project here. It should paint a

问题 I am trying to change the storage location of Java Web Start. I read that the location is changeable through the java control panel. I got there and I can see the path of my "temporary internet files" but the "change" button is gray. Why can't I change this path? I need to change it to another hard drive. 回答1: I googled it for you. This was my search phrase: java console change temporary location And this was the result that was most appropriate: How to change Cache location for Java on

问题 Everything works in my Java EE project when I'm running it from Netbeans, but when I deploy it in Glassfish server and run downloaded JNLP file, some added libraries don't work. Any ideas? 回答1: Any library that your program needs that is not part of the standard Java SE distribution must be referenced in the JNLP file. Part of your JNLP file might be: <resources> <j2se version="1.6+"/> <jar href="serdarsProject.jar" main="true"/> <jar href="lib/activation.jar"/> <jar href="lib/mail.jar"/>

问题 We are trying to develop a printing application using java webstart. We created the jar as a normal jar file using eclipse. Our application needs external libraries for connecting to the database, converting the data to bytes etc. We were able to do this before by putting the necessary jars in the /ext/ directory of the jre folder. However this caused a library conflict with our tomcat server so we would like to avoid this approach. We also tried exporting the project as a runnable jar as the

问题 This is my first time trying to use Web Start, and I am trying to launch my runnable jar. I get the following error from my webpage as I click the link to launch the jar. Can anyone help me out? The Notepad example from the tutorial works fine from another link on the test page (JNLP and jar in same folder as I have too).
