Hi,
i have written a Swing application which works fine, but not with JavaWebStart 6.
Wenn i start it from the CMD with the java -jar MyApplication.jar command or with eclipse it works. But when i try to do the same with JWS 6 i get an IOException.
In the .jnlp i have:
<security>
<all-permissions/>
</security>
How can i fix this problem?
I'm thankful for any helpfully information.

What is the stacktrace (first 50 lines)?

><all-permissions/>
> </security>
Java 6 does not verify anything but jar's,
what is the rest of this JNLP file?
Hi AndrewThompson64 and all the others,
this time i get another Exception.
java.lang.ClassNotFoundException: com.myPackage.Main

this is my .jnlp
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://mySite.com:8080/swing/" href="myApp.jnlp">

</security>
<application-desc main-class="com.myPackage.Main" />
</jnlp>
But when i try to start the application with the
java -jar MyApp.jar
it works perfectly.
?
What can i do to make the application work with JavaWebStart 6?

I see some suspicious paths in the JNLP..
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="http://mySite.com:8080/swing/" href="myApp.jnlp">
<information>
<title>My App 1.0</title>
<vendor>Myself</vendor>
<homepage href="http://www.mySite.com" />
<description>Swing App</description>
<offline-allowed />
</information>
<resources>
<j2se version="1.4+" initial-heap-size="128m" max-heap-size ="512m"/>
<jar href="swing/MyApp.jar" />
...
Given the codebase ..
http://mySite.com:8080/swing/
..this element suggests the jar
should be located here..
http://mySite.com:8080/swing/swing/MyApp.jar
Is the jar located there, or is it really at..
http://mySite.com:8080/swing/MyApp.jar ?
If the latter, try changing the jar element to..
<jar href="MyApp.jar" />
Hi
i had finished this project few months ago, but now i have to find out why it isn't working with JWS 6.
The ClassNotFoundException was because i used an old .jnlp (blush)
After corection it works and i get the previous Exception.
When i start the application from the cmd or eclipse it works fine. I didn't find a better way to
print the stacktrace:
