Re: The version of the JVM must be 1.8?

you need to distinguish between the JVM that OWS needs to run and the JDK your jnlp application needs to run. The JVM bundled with OWS is not the one used to launch your application (https://openwebstart.com/docs/FAQ.html#_i_saw_there_is_a_bundled_jre_installed_together_with_ows_can_i_use_it). When ...

Re: The version of the JVM must be 1.8?

could you give more details on your problem? Do you talk about Java Webstart or OWS? It looks like you run Java Webstart and need to install a suitable JVM to run your script

Re: Could not read or parse the JNLP file

Looks like it does not find the file and the file suffix (.jnlp64) looks also strange.

More details on the JNLP file and the logs are required to help you there:

Re: Java 17

When I look into the code of OpenWebStart, I can see an implementation of BasicService.getCodeBase() (net.sourceforge.jnlp.services.XBasicService#getCodeBase, in the IcedTea-Web Part), so it looks to me that your required functionality is around. Did you gave it a try?

Re: Start an e4-RCPe application using OWS

I'm not aware of a possibility to launch .exe using OWS/JNLP. Maybe you can wrap the .dll/.exe in a .jar file, and reference it in your .jnlp file using <nativelib>. Anybody in the forum here have some experience with that?! Just out of curiosity, did you manage to run your exe application with Orac...

Re: JRE

You need to give more details on the settings of this particular machine as JVM downloading behavior in OWS depends on various other aspects, such as your other JVM Manager settings (jnlp precedence settings, vendor restrictions, etc.) and if you have activated/deactivated some JVMs in your JVM Mana...

Re: File association

I'm afraid custom extensions described by association tag is not implemented yet in OWS. OWS is parsing the tags in jnlp but does not registering these information with the operating system as the primary handler of these extensions / mime-type.

Re: Could not initialize application

guess the problem is what the exception says: you have to sign your jars to run your application.

Re: error generating xml files

Really looks like your javax class is not longer included in the JVM you are using. In this case you have to add the javax activation jar to your jnlp.

Re: own Java client download

there is a pretty good documentation how to setup your own download server:

for an example json file, have a look at:
http://download-openwebstart.com/jvms.json

tar.gz and zip is both fine

can you add the following lines deployment.log.file=true deployment.log=true deployment.console.startup.mode=SHOW to your "/home/<your user>/.config/icedtea-web/deployment.properties" file to enable logging manually without using the UI. If you do this, OWS should log to file (/home/<your ...

Re: OpenWebStart Support for RHEL

Was this your first try with OWS 1.4.0 on RHEL8.4 or did it work before (older version of OWS resp. RHEL)?
