Can't launch .jnlp witch IcedTeaWeb

[thikool825]

Hello,

currently I am trying to simply launch a .jnlp-File via IcedTeaWeb. After a short period, i get the following error message:

at net.sourceforge.jnlp.Launcher.fromUrl(Launcher.java:489) at net.sourceforge.jnlp.Launcher.launch(Launcher.java:289) at net.sourceforge.jnlp.runtime.JnlpBoot.run(JnlpBoot.java:67) at net.sourceforge.jnlp.runtime.Boot.run(Boot.java:274) at net.sourceforge.jnlp.runtime.Boot.run(Boot.java:63) at java.base/java.security.AccessController.doPrivileged(AccessController.java:318) at net.sourceforge.jnlp.runtime.Boot.main(Boot.java:214) Caused by: java.io.IOException: java.lang.NullPointerException: name can't be null at net.sourceforge.jnlp.JNLPFile.openURL(JNLPFile.java:319) at net.sourceforge.jnlp.JNLPFile.(JNLPFile.java:241) at net.sourceforge.jnlp.JNLPFile.(JNLPFile.java:215) at net.sourceforge.jnlp.JNLPFile.(JNLPFile.java:200) at net.sourceforge.jnlp.JNLPFile.(JNLPFile.java:186) at net.sourceforge.jnlp.Launcher.fromUrl(Launcher.java:453) ... 6 more Caused by: java.lang.NullPointerException: name can't be null at java.base/java.io.FilePermission.init(FilePermission.java:323) at java.base/java.io.FilePermission.(FilePermission.java:490) at java.base/java.lang.SecurityManager.checkRead(SecurityManager.java:756) at java.base/java.io.FileInputStream.(FileInputStream.java:146) at net.sourceforge.jnlp.JNLPFile.openURL(JNLPFile.java:317) ... 11 more

I am behind a somewhat restrictive proxy/firewall, but have no idea if it is this what is causing my issue. I have absolutly no Idea how to solve this issue and am thankful for any help I might get on this.

Thanks in advance!

You can run the itweb-settings app to set the appropriate Network Proxy settings.
