Please check that by typing/pasting the URL https://socpos.mpsv.cz:443/posvvaclient/iokposkytovatel.jnlp in a browser it is downloading the jnlp file. Can you please try after cleaning the OWS application cache? You can do this using itw-settings application or you could manually delete <User Home>\...

Can you please post the OWS logs?

Are you still getting "Caused by: java.lang.RuntimeException: JarIndex not found!". ? This is fixed in OWS 1.9.0. Of course you can specify the Java version you want to use to start the application in your Jnlp file. What have you specified in your Jnlp file. Also what does your JVM Manage...

There 3 places that OWS tries to find the certs for verification: During Phase I when it gets the jnlp file: In the bundled jre\lib\security and UserHome\.config\icedtea-web\security During Phase II when it gets the resources and starts the app: In the jre\lib\security that best matches the one spec...

The cert may not be present in the keystore of the jre or OWS. If you trust the cert then choose "always trust contenet from this publisher" .

You can see the certificates in keystores using the itw-settings app.

We are happy to announce the release of OpenWebStart v1.9.0

We have fixed the jar cache key to use Url string instead of the Url. We are hoping that this would fix the problem. we are planning to make a release this week. You can try the new release.

Planned for this week unless there are some issues.

PS: we are using log4j2.17.1 which I noticed was flagged in another thread here as problematic but I am not sure if for the same reason

Hi, Thanks for registering with the forum. There is already an issue : https://github.com/karakun/OpenWebStart/issues/530 What happens if you disable the console using the itw-settings app? Unfortunately we have no plans and resources to fix the memory leak due to console at present. Could you consi...

Hi The order in which the resources are specified matters. If you switch the order of x86 and x86_64 as follows it will pick up vmargs for x86_64: <resources arch="x86_64"> <java version="17*" vendor="Eclipse Adoptium" java-vm-args="--add-exports=java.desktop/sun.s...

I am able to reproduce the problem on Intel Mac with the following Jnlp file: ... <resources arch="x86"> <java version="17*" vendor="Eclipse Adoptium" initial-heap-size="511m" max-heap-size="1023m" /> <jar href="generated-jars/jvm_args.jar"...

This has been fixed https://github.com/AdoptOpenJDK/IcedTea-Web/pull/925 and will be part of the next release.

We have created an issue and will try to fix in the upcoming release. Probable fix could be for OWS/ITW to ignore loading classes from Jar Indexes for JDK >= 21 https://bugs.openjdk.org/browse/JDK-8302819 " https://www.oracle.com/java/technologies/javase/21-relnote-issues.html#NewFeature core-l...

I could reproduce.

With Java 11,17,18,19,20: App runs even if sun.misc.JarIndex not found, jdk.internal.util.jar.JarIndex is found and used.

With Java 21 jdk.internal.util.jar.JarIndex is not found.

I will try to reproduce it and revert.

Ok Thanks for the sample. I will try to reproduce it.

> As it is a GET call, the application create the <jar> with the sessionId (found in the request done to build the jnlp file) I could reproduce the issue by generating a jar on the fly. I will investigate your issue and check if caching can be improved. However, I would still request that you consid...

> jar href='{apiUrl}/{jarName}?JSESSIONID=rsoklofhej136qcq0unu2c7smf It seems you have edited the logs as the Jnlp file has some place holders. I would like to see the Jnlp file that is actually processed by OWS. In your Jnlp the url of jar file has been rewritten to include the session id. Is the J...
