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)?

You have to change file association on your OS to point to OpenWebStart. When click on a .jnlp Link in the browser a O...

Re: Is it possible to use a single jar file to start as an applet and as an application?

I don't see any issue in doing this, having a jar file with a regular Java application main that you run with OWS. As long as you run it with a JNLP and application-desc. OWS does not support Applets but it does not care if there is code in it that is not used.

In your second file that you describe as running as an application it looks like you also using the applet-descr tag instead of the application-descr tag

Re: javax.jnlp.UnavailableServiceException: javax.jnlp.IntegrationService

There are limits in the supported jnlp-APIs. As OWS is based on IcedTea-Web you may observe the same behaviour if OWS does not complete or renew a feature. Implementations (OWS + IcedTea-Web) are provided for SingleInstanceService, SingleInstanceListener, ServiceManager. A good overview of what is p...

Re: Need to download JRE from Unix Server JDK

First you have to put your .json to your custom download server.
Then replace the default download server URL in ITW settings (which by default points to https://download-openwebstart.com/jvms.json) with the URL that point to your custom server.

Re: Remove JAVA

when you clean all previously installed Java runtimes, OWS itself (and OWS Settings) is still running (as it comes with its own internal JVM). But whenever you want to launch a JNLP application via OWS, you need to install at least one JVM that meets the needs of your JNLP application. Otherwise OWS...

Re: Hardcode JVM Path

The information about the available JVMs is stored in a file called cache.json that can be found in the .cache/icedtea-web/jvm-cache/ folder where also the cached JVMs of your installation reside. You can use the configuration property "ows.jvm.manager.cache.dir" in your response.varfile to redirect...

I'm afraid there is no such a FAQ specific for security for OWS as far as I know.

We then can collect the answers and extend the existing...

To narrow down the problem, do you have the same behavior when you associate ".jnlp" extension in your IE11 to OpenWebStart, or does this combination behaves as expected?

Re: No suitable JVM was found to start the application

It sounds like you do not have configured a suitable JVM in your OpenWebStart settings that matches to what your JNLP application requests. The version and vendor settings in your jnlp file determine which JVMs are possible (e.g. <java version="1.8*"> or <j2se version="1.7+" vendor="Oracle"/>). Depe...
