> Description: Oracle Forms Services applet launcher.
> Launching Applet

OWS does not support applets. Please migrate your application to a standalone Java application that can be specified as application in the jnlp file.

> If the current way is not correct I can probably make some time to improve this

I have pointed to the Class and method. You are welcome to improve upon it and create a Pull Request.

We had a brief look.

Is it possible for you to sign the jars with certificate chain that includes the CA cert?

https://github.com/AdoptOpenJDK/IcedTea ... ifier.java has a method isTrustedTsa which is doing the check.

I did not get time to go through the jar signing code yet. I will have a look in coming days but cannot promise when. For guaranteed response time, please consider paid support : https://openwebstart.com/support/

Shouldn't the server set the mime type in response when responding to request for a jnlp file?

I will have a look and revert.

I will investigate this. But just to clarify I would like to know the steps you followed: 1. You have deployed a myapp.jnlp file in a server say myserver.com in app folder 2.

Please talk to the vendor if possible. It should not be difficult to migrate an applet to an application.

You are trying to run an applet : <applet-desc ...> as specified in your jnlp file .

Log file has: [ITW-CORE][2024-08-22 14:12:41.057 EDT][DEBUG][net.sourceforge.jnlp.Launcher] Launching Applet

OWS does not support applets.

You will have to convert your applet to a Java Application.

Which version of OWS are you using? Can you please attach the OWS logs? Which JREhave you specified in your Jnlp file to run the application?

Please see https://openwebstart.com/docs/OWSGuide. ... management.

Please make sure that you have chosen the right JVM download/update strategy.

You can control JVM choices using itw-settings > JVM Manager > Settings. Please see https://openwebstart.com/docs/OWSGuide. ... management

You can add appropriate --add-modules jvm args in the jnlp file to be able to run your application with Java 11. You can specify which JVM you want to use to run your application in the jnlp file and in the itw-settings.

OWS is starting your jnlp app by invoking the main method of your app. There are exceptions in your app:: ITW-APP ][2024-06-26 07:36:16.224 MST][ERROR][java.base/sun.nio.cs.StreamEncoder.writeBytes(StreamEncoder.java:233)] Jun 26, 2024 7:36:16 AM com.sun.enterprise.v3.server.CommonClassLoaderService...

Please attach the OWS stage1 and stage 2 log files from the time you run you run your jnlp with OWS. Please do not copy log from console to post here.
