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

OWS works like for Oracle Java Web Start which was discontinued by Oracle from Java 9 onwards. Oracle JWS is described here : https://docs.oracle.com/javase/tutorial/deployment/deploymentInDepth/jnlp.html OWS implements most features of JSR 56 : https://www.jcp.org/en/jsr/detail?id=56 OWS is describ...

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.

Stage 1 log says Launching Applet Your application is an Applet. OWS does not support Applets. The Jnlp has Applet tag. Your main class must be deriving from Applet or JApplet. <applet-desc main-class="com.hp.ilo2.intgapp.intgapp" name="iLOJIRC" documentbase="https://ilo-rhv...

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.

Please see the OWS guide: https://openwebstart.com/docs/OWSGuide. ... n_manifest

Please enable redirect in OWS as described in the link below :

Can you please send the logs of the time it runs and fails with OWS 3.0.0?

Will it be possible for you to provide a small example or allow us to run your Jnlp from our machine?

Can you provide us with a sample to reproduce the issue?

Can you try running with https://github.com/karakun/OpenWebStar ... 0.0-alpha2 and let us know if it worked?

Does your app run with Java 17 in standalone mode?

Please check if these classes are supported by Java 17? You will have to export modules or find alternative libs.

Could not read or parse the JNLP file at 'file:/C:/Users/Harald/Downloads/accesscard%20(1).jnlp'

Please check if the Jnlp file exists. Also please remove blanks from the jnlp file name.

Can you please send the log with https://openwebstart.com/docs/OWSGuide.html#_logging

You seem to be using Icedtea-web and not Open Web Start. Please use Open WebStart and if that does not work send the log file. Please don't copy logs in the post.

Thanks very much for sharing the solution. Would it be possible to provide a small snippet of your application which is using "some appender implementations which use PatternLayout class from log4"? We can then debug why OWS was not able to find classes with Log4J 2.17.1 and why it is work...

HI Your Jnlp specifies JRE version "requested: JRE with version string '1.7+" OWS finds adn uses "using java runtime at '/home/leonardo/.cache/icedtea-web/jvm-cache/adoptium_11.0.15_x64'" Your application is using class javax.activation.DataHandler : it.finanze.entrate.sfe.xmlcon...

Just to confirm that when you run the jnlp file with OWS on Win and Mac the app runs but the same jnlp file does not run on Linux?

Can you please send the logs from the time it runs on Win and from the time it fails on Linux?

Please see https://openwebstart.com/docs/OWSGuide.html#_logging

Ok. Good to know.

OWS is starting your application but your application is crashing because it cannot find an class javax.activation.DataHandler. May be the JRE that was chosen to run the application does not have this class. Please send the openwebstart log files by enabling logging as described here: https://openwe...
