Re: How to Suppress Security Approval's digital signature.

Do you get this dialog even after you run the application once after choosing "Always trust content from the pubisher"?

Re: Default Open JDK

OWS is not working when the Jnlp application is run with JDK 18. OWS is using the class SecurityManager which seems to have been removed from JDK 18. https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/SecurityManager.html We will investigate this. Thanks for pointing out this err...

Hi, In a Terminal server environment where there are going to be many users you can choose to have a System wide configuration for OWS: https://openwebstart.com/docs/OWSGuide.html#_system_configuration Within this you can Customize Application Cache and User Config Location.

Re: Default Open JDK

You can install a JRE locally and in itw-settings you can add that local JRE to OWS's list of JVMs. You can control the download of JVMs by OWS using the Update Strategy of JVM Manager Configuration. Usethe strategy "Do not download any version" to prevent OWS from downloading any JVM. Not...

Re: jnlp is not signed

Does your main jar contain signed jnlp?

Please see the documentation on signed jnlp at https://docs.oracle.com/javase/7/docs/t ... dJNLP.html

Re: Include a JAR file in the CLASSPATH

Doing this kind of thing would have security concerns. We don't think this would be possible.

Re: Error while launching OWS from another User

This is not an OWS issue. You should install OWS on your machine such that all the users that need to use have proper access rights as OWS tries to temporarily store downloaded resources and cache them. For this it requires necessary access rights to the system.

Re: Exception in thread "AWT-EventQueue-0" java.awt.HeadlessException:

itw-settings is a simple Java Swing based app.

You should set up your display properly to be able to run a Java Swing app.

It seems that Swing is not finding a display and thus giving HeadlessException.

Please send the OWS logs and make sure that all jars specified in the Jnlp file are signed and signed with the same certificate

Please do a search https://www.google.com/search?client=f ... outHandler .

You may find some solution. It seems this class is not longer supported after Java 8.

Re: Blank/empty window on RHEL9 w/ OpenWebStart 1.6.0

but creating a test.jnlp file with your suggested content:
I did not suggest the content for jnlp, I merely pasted the content from your jnlp to point out that it has the applet tag, meaning the application you are trying to start is an applet. OWS does not support applets.

Re: JNLP Injection Exploit?

Hi

We have seen this document earlier.

OWS allows you to specify a server whitelist for downloading jnlp and jars so that you can download signed files jnlp and jars from a trusted server using https.
