SOLVED: window closes when trying to redirect media

Post by mps.esupp »

Hi

I'm somewhat technical, but not completely, so I'm sorry if I use any of the wrong terminology/things aren't clear.

We use OpenWebStart to open jnlp files to launch the JViewer window to remotely connect to CPE servers. Part of our requirements are to boot these servers from an ISO hosted on my local machine.

We would normally do this by selecting Device >> Redirect ISO. But as soon as we select the image on the local machine, the JViewer window closes.

I've checked the logs, but there's nothing obvious from it.

Has anyone experienced this before and/or has a fix?

Thanks

Please share your OWS logs. In case the logs have sensitive data, please zip and send them to openwebstart@karakun.com. However for guaranteed response and private channel we recommend that you could buy paid support: https://openwebstart.com/support/

Thanks, taking a look at those now. OWS jvms.json file doesn't have any of the jvms recommended in those links, but I'll keep searching!

This helped me resolve the issue.

I installed x86 OpenWebStart, then loaded a corresponding x86 JVM from https://download-openwebstart.com/jvms.json (I chose jdk8u472).
