NodeManager problem

[Martin Matthews]

Hi there

I have Weblogic 6.1 installed on 3 Sun boxes running Solaris 8. One machine
is has Weblogic running as the Admin server, the other two have NodeManager
running and are intended to be running Manager Servers. I can start the
Managed servers on the two machine using the supplied start scripts but when
I try to start/kill them using NodeManager I get the following error:

<17-Sep-01 17:53:09 BST> <Info> <NodeM...@192.168.10.13:5555>
<BaseProcessControl: saving process id of Weblogic Managed server
'ManagedServer01', pid: 322>
Starting WebLogic Server ....
Child exited

***************************************************************************
The WebLogic Server did not start up properly.
Exception raised: java.lang.NoClassDefFoundError:

Reason: Fatal initialization exception

***************************************************************************
<17-Jul-01 17:54:17 BST> <Error> <NodeManager> <CommandInvoker: Socket
read timeout - no output for 60 seconds>

I have set up the Startup parameters for each of the machines and they
contain the correct classpath.
(WL_HOME/lib/weblogic_sp.jar:WL_HOME/lib/weblogic.jar) and totally confused
as to why this is happening as I have set up these clusters before and not
had a problem. Admittedly they were all on NT.

Anyway, thanks in advance for your help.

WLS 6.1 requires JDK 1.3.1. It looks like you are trying to run an
older version.

Cheers for the reply Rob but Weblogic 6.1 ships with JDK 1.3.1. This is also
specified in the startup scripts (JAVA_HOME) for NodeManager which should
then be passed onto the ManagedServer that NodeManager is asked to start.

Any other ideas?

Indeed, but I'd recommend that you check again.
java.lang.ref.InvocationHandler is distributed with JDK 1.3.x. You
shouldn't get a NoClassDefFoundError on it. It won't be there in <
1.3.x JDKs.

Do you have older JDKs installed on the target machine?
You might also consider running the java vm with the -verbose switch so
that we can see which classes it is loading.
