Designer Launcher Problem


I’m trying using Ignition Demo on a MAC. (I tried it on Windows 7 and it worked well).
I follow the installation guide and i’m able to Run/Stop/Restart Ignition.
I’m able to configure settings (Database and OPC connection) and connections are good.
When i try to launch designer, firefox download a file “designer.jnlp” and i run it using “Java Web Start”. Application starts loading but never ends! (attached picture).

My info:

OS: Mac OS X Version 10.7.5
Java: 1.7
Browser: Firefox/Safari

Oracle introduced a regression/bug in Webstart with Java 7u9 which hasn’t been fixed yet. The only quick work-around for now is to edit the JNLP file and remove java-vm-args="-XX:MaxPermSize=128m" from any lines that contain it.

For example:

    <j2se version="1.6+" initial-heap-size="32M" max-heap-size="512M" java-vm-args="-XX:MaxPermSize=128m"/>
    <j2se version="1.5+" initial-heap-size="32M" max-heap-size="512M" java-vm-args="-XX:MaxPermSize=128m"/>

Would become:

    <j2se version="1.6+" initial-heap-size="32M" max-heap-size="512M" />
    <j2se version="1.5+" initial-heap-size="32M" max-heap-size="512M" />

You will then be able to launch by double-clicking the JNLP file for the time being.
