Hi,

I am trying to get JRUN w/MyEclipse working with Java 5.0. It works fine with the 1.4.2 JDK within Eclipse. JRUN is running (outside of eclipse) on jdk 1.5. My new project requires th use of Java 5, so I really need to get this working. The error was the same error I got form JRUN before I upgraded to Updater 6.

Any help is appreciated.

I am getting the following error when I start the server:

This error is indicative of incompatible versions of Java, you see there that JRun is dying because of the incompatible version of Java’s management implementation. Does JRun run outside of MyEclipse with Java 5? I would guess probably not, have you checked JRun’s site to see how to make it Java 5 compatible?

[James Camire]

JRUN is running outside of Eclipse on version 5. I was getting this same error message from JRUN (outside of Eclipse) before I upgraded to Updater 6. Both Eclipse and JRUN are pointing to the same JDK (1.5.0_04)

I can change code and deploy it within the MyEclipse perspective. However, to test/view the web pages, I must start JRUN outside of Eclipse.

[Riyad Kalla]

Did you be sure to change the JDK you told MyEclipse to luanch JRun with? (Window > Prefs > MyEclipse > App Servers > JRun 4 > JDK?)

Changing the JDK you run MyEclipse with won’t immediately change the JDK you run your app servers with, you can use the JDK settings (path shown above) to do that.

[James Camire]

I had changed the JRUN Settings to the new JDK when I upgraded.

Update: I have downloaded and installed JRun + Updater 6 and am working through this now, hang tight.

jcamire,
I have reproduced the problem you encountered and we are working on fixing this issue. There currently doesn’t seem to be a workaround for starting it from withing MyEclipse, however you will still be able to debug and work with JRun by using our Remote Debugging features as outlined here: http://myeclipseide.com/enterpriseworkbench/help/index.jsp?topic=/com.genuitec.myeclipse.doc/html/quickstarts/remotedebugging/index.html

The developer working on this has found a simple workaround for the time being:

Workaround: Simply adding “-Djmx.invoke.getters=true” works around the issue and allows the server to launch correctly.

Great, so … that just leaves…

1) How to set the system property given that the usage docs for jrun.exe and jrunsvc.exe don’t include java properties ?

2) How do we update the Windows service to start with JRun with the new property ?

3) If this is the “workaround”, is there a non-workaround alternative? Would running with JDK 1.4.2 fix the problem without the properties ?

[James Camire]

I have run across this problem and was able to reproduce it. I fixed it by doing the following:

1) Unistall all files associated to jrun
2) Make sure JDK 5 is installed
3) Install JRUN 4 normally. DO NOT start the server
4) Install Updater 6
5) Start JRUN
6) In MyEclipse preferences, add the following lines to the JRUN appserver JDK vm args

-Dsun.io.useCanonCaches=false
-Djmx.invoke.getters=true

I hope this helps. I have it running on 3 seperate machines with no problem. I am using Eclipse 3.1.2 and MyEclipse 4.1.1

[dwmiller44]

Thanks! I’ll try it.

Also found <jrsun>/bin/jvm.config file, where -Djmx.invoke.getters=true could be added to the java.args list
