In theory activating the checkbox should add the certificate to OWS and by that the dialog will not appear again. It is possible that the dialog is spawned by multiple threads within a few milliseconds and thus it appears that the checkbox does not work because all the dialogs will pop up even if th...

java.lang.NullPointerException: name can't be null

Usually points to a problem in downloading the JNLP file.

The nature of this suddenly appearing and also for all users and you not have changed any of the admin privileges at that time points to the keystore file. Maybe this was changed. My first guess would be that the access rights to the file has changed. This can be cause by different operations. Can y...

ok, the log ends abruptly. I assume after the last log line the error from your initial post follows. [ITW-CORE][2022-02-15 16:50:13.458 EST][INFO ][net.sourceforge.jnlp.Launcher] Invoking main() with args: [COM9, https://10.0.8.140:8843/TDT_CFS, E5BECAA6095FD9AB9E5E8F505BB00A93] [ITW-CORE][2022-02-...

Can you please enable all debug logging (incl logging of jnlp file) in the settings and post the logs here.
The above dump would be required if you want to report this at https://github.com/adoptium/adoptium-support/issues

Janak, I suspect the log4j config has an influence on which classes log4j is loading (and maybe even how it is loading them).

We have heard of others with similar problems.
It would be really great if you could create a minimal reproducer application such that we can debug this issue and fix it.

yes and no, There is a bundled JRE installed together with OpenWebStart (OWS). But this JRE cannot be used for running applications. This is a precautionary measure as we regularly change this bundled JRE and we do not want to break any working application. Instead OWS has a JVM Manager which can fi...

If a JNLP can be launched then it works. The installer manly does the following steps: - copy all files to the disk (for linux this is /opt/OpenWebStart) - register OWS as an executable for *.jnlp and *.jnlpx files - register an icon for *.jnlp and *.jnlpx files The second and third steps are not re...

Sorry we do not have the resources to support more than .deb at the moment.
Non of the devs is currently using a rpm based package manager.

If you find a solution to your problem we are very great full if you can post it here so that others with the same issue can find a solution.

by passing the --nosecurity you disabled all security in OWS and ITW.
There is not more things to disable.

Do you know if your application is defining its own SecurityManager?

You can pass this only on the command line.

Open a powershell or cmd window and navigate to your jnlp file.

Then enter the following command "javaws <name of your jnlp> --nosecurity"

Proxy with user/pw is indeed supported. But other means of authentication against a proxy are not

So the problem is specific to the setup with the WAF.

Can you provide us the debug logs. Without them we will not make any progress.
If you are concerned about the content of the logs you can also send them to openwebstart@karakun.com instead of posting them here in public

Can you pass "--nosecurity" as an argument to javaws when launching the JNLP.

We also just released version 1.5.0 which has improvements which may help in your case.
So please give it a try and send us a fresh set of log files in case you still encounter the problem

We will investigate this

I am a little confused. You mention that you have renamed the files and also the href. But in your last post the files are still called the same. Please make sure to rename the files on the server, as OWS will download the latest version on the server and use that. So only renaming the file locally ...

Have you also changed this on the server. Because OWS will download the latest version of the JNLP from the server and use that instead of the one on your filesystem.

OWS is basically a wrapper around ITW 2.x
Did you ever experience this behavior with ITW?
