Icegridnode Java home

Hi

I have a service running in Icegrid 3.4.1 on Windows 2003. The Path for the system has been changed to point to a separate (non-system) version of Java and the box rebooted, but the java executable being run is the system version.

System Environment variables
JAVA_HOME=F:\Aurora\Java
PATH=F:\Aurora\Java\bin;C:\tibco\tibrv\8.2\bin;...

Using ProcessExplorer the environment variables for the icegridnode.exe process are correctly set, but the properties in the log file for the service have java.home => C:\Program Files (x86)\Java\jre6.

Opening a command prompt as the same user and running a main method which dumps the properties from the jvm, has the correct java.home => F:\Aurora\Java\jre

Please could you tell me how to get icegridnode to use a specific non-system java version.

Thanks Nim

    Hi,

    I'm not sure why your server is being executed with the wrong version of Java. Are you running IceGrid as a Windows service?

    IceGrid doesn't take any special action for Java servers. In fact, IceGrid doesn't even know what language a server uses. If you want to eliminate any possibility of using an incorrect JVM, you can modify the executable path in your descriptor as follows:
    <server id="QlibPricingService-${index}"
    exe="F:\Aurora\Java\jre\java" activation="always" ...>

    Regards,

    Need JRE not JDK java executable

    Hi Mark

    Thank you for replying.

    I had tried

    <server id="QlibPricingService-${index}" exe="F:\Aurora\Java\bin\java" ..

    before but the service didn't start up.

    I've just successfully tried <server id="QlibPricingService-${index}" exe="F:\Aurora\Java\jre\bin\java"

    ie pointing to the jre instead of the jdk java executable.

    Hope this helps someone else.

    Thanks Nim
