> What exactly did the "javaws.exe -Xclearcache" command clear? I assumed it will get rid of all the cached data.

It clears the applications cache - all the cached jnlps and jars.

jvm-cache is for caching the downloaded jvms that are used to run jnlp applications.

I tried reproducing this but could not. On my machine I had .jnlp associated to Oracle JWS using Settings > Choose Default Apps By File Type. .jnlp file were showing Java icons.

You are using OWS 1.4.0 : Stage 1 log says "Starting OpenWebStart 1.4.0".

Please try with the latest version of OWS 1.7.0 and send the logs. Please enable debug level logging and logging content of jnlp.

I understand that: 1. you have instrumented the the application which you have specified in your Jnlp file and which you want to run using OWS. 2. In the jnlp file you have specified the JVM which will be used to run the application. 3. To this JVM you want to pass the argument like -javaagent:<agen...

You can attach the <date-time>-ows-settings.log file.

Is your deployment.properties file corrupted by any chance? You could rename that file and try starting itw-settings.

Which version of OWS are you using? Can you please post the OWS logs?

Looks similar to https://github.com/karakun/OpenWebStart/issues/172

May be you can try with https://github.com/karakun/OpenWebStart ... 0.0-alpha2

I could download the logs. In Stage-2 log, the log entry at line 983 " Starting application [kim.appli.frame.entryadm.Launcher] ..." So OWS is able to start the App. There is no ClassNotFound exception in the logs. There is an error though in your application: [ITW-APP ][2023-02-06 15:35:1...

Could not download: "The transfer you requested has been deleted."

Please send the log files generated by OWS.

Can you please send the OWS logs?

Seems your application is spawning a thread and using own classloader which is not able to load the required class from the jars on the classpath of OWS's JnlpClassloader.

We had to update OpenWebStart v1.7.0 installers due to an expired code signing certificate.

Please get updated installers from https://openwebstart.com/download/

Please share the stage1 and stage2 logs.

Yes we will add Java 17 links to the JVM JSON it.
We are likely to make a new release of OWS next week.

It is difficult to go through logs when copied in the post. Please attach your jnlp file and the logs (please read the documentation on how to enable logging to a file).

You say "Of course, I specify FXWebStartLaunche.jar in my JNLP file." But did you specify the Launcher class in the application tag?

Please share your jnlp file.

Sorry we have no experience with MS Intune.
