Hi I got this problem in some of the servers and now found solution but dont know why this happends. Problem: From some of the ignition gateways does not launch jnlp files anymore. Designer.jnlp and project.jnlp is downloading right and all permissions and java settings seems to be right. I check those jnlp files and compare those on jnlp files which are working and I found small difference on Resource section. jnlp file which is not working: jnlp file which is working: Just ripping those java-vm-args… string out makes jnlp file working again. And I can run designer or project. So I guess this is problem of different Java versions on server and client. Hope somebody can help this more so I dont have to manually fix jnlp:s to use ignition. System: osx 10.6.8 Java 1.6.0\_37-b06-434 Br Tommi Vahtera ---

There’s a bug in Oracle’s Java 7u9 and later affecting OS X and Linux systems. (and 6u37 on Mac, which is either using the same faulty webstart code or redirecting to 7 webstart, can’t figure out exactly what happens). Remove ’ java-vm-args="-XX:MaxPermSize=128m" ’ from both lines that contain it and then launch the designer/clients from the JNLP file for now. ---

You would have to downgrade to Java 6. ---

Hi I tried to downgrade to java6 but now launching jnlp get message that I need java environment and link goes to download Java7. Should I do something else to make Java6 work again? Br Tommi ---

Because of this issue we’re looking at some alternative ways to web-start to launch clients that should be in Ignition 7.7 ---

I saw your presentation on the new launcher at the conference and thought to myself, “I’ll just keep doing it the old way…I’ve not had any issues”. Now this week I have several projects that are getting installed on MacMini’s and I ran into this issue. Thank goodness for this forum…got it running, but I can see that I’m going to get used to using the new launcher in 7.7. Thanks for the awesome conference! To everyone at Inductive. Michael ---

The client launchers will be available in the next point releases as well; you don’t even have to wait for 7.7! 🙂 7.5.11 and 7.6.4 should both include the launchers. ---

When will 7.5.11 be released? I have an issue with text component keyboard popup that an upgrade from 7.5.8. to 7.5.10 broke. Ticket was already made for this issue. ---

We are looking to release 7.5.11 within 2 weeks, followed by 7.6.4 soon after that.
