Java code to access the shared heap

Hi

Help needed and forgive me as I dont know Java so please bare with me.
I have searched this site and google but was unable to locate the information I need.

An application that we use - is based on java and stores some performance counters etc internally in the shared JVM. They are not held in an oracle db etc

What I want to be able to do is access the shared area in JVM and write out the contents, I am not 100% sure how the counters are stored etc so I would need to access the entire JVM memory and write it to a file on the unix filesystem assuming thats even possible..

Can you help? Smilie

Server information:
java version "1.4.2_10"
Solaris 10

wbemconfig(1M)						  System Administration Commands					    wbemconfig(1M)

NAME

       wbemconfig - convert a JavaSpaces datastore to the newer Reliable Log datastore format

SYNOPSIS

       /usr/sadm/lib/wbem/wbemconfig convert

DESCRIPTION

       A Reliable Log directory is created that contains the converted data. This directory is named /var/sadm/wbem/logr.

       The  convert  argument  is the only supported option of this command. You should only run this command after stopping WBEM (CIM Object Man-
       ager) with the init.wbem stop command. Otherwise your data may be corrupted.

       This command successfully converts any proprietary custom MOFs you have created in the datastore, but not any CIM or Solaris MOFs you  have
       modified. These will be destroyed. To recompile any modified CIM or Solaris MOFs into the new datastore, run the mofcomp command on the MOF
       files containing the class definitions.

       Because the wbemconfig convert command invokes the JVM (Java Virtual Machine) to perform conversion of the JavaSpaces datastore,  you  must
       be  running  the  same version of the JVM as when the original JavaSpaces storage was created. After the wbemconfig convert command is com-
       pleted, you can change to any version of the JVM you want.

       To see what version of the JVM you are running, issue the java -version command.

OPTIONS

       The following options are supported:

       convert	       Convert a JavaSpaces datastore to the newer Reliable Log datastore format.
