Add a parameter to the java command for java plugin server to troubleshoot. This parameter reports which jar file a class is loaded from.

For this scenario add the option in the java command within the armonitor.conf.

Use the option -verbose:class on the java command line.

Here is an example.

/usr/jdk/latest/jre/bin/sparcv9/java -Xmx512m -verbose:class -classpath /usr/remedy/ARSystem/pluginsvr:/usr/remedy/ARSystem/pluginsvr/arpluginsvr81_build001.jar:/usr/remedy/ARSystem/approval/bin/armaskingImpl81_build001.jar:/usr/remedy/ARSystem/api/lib/arcmnapp81_build001.jar com.bmc.arsys.pluginsvr.ARPluginServerMain -x myservername -i /usr/remedy/ARSystem

Below is a snippet of that output:

-----------------------------------
[Loaded com.bmc.arsys.arrpc.nio.ArTcpServerTransportBase from file:/usr/jdk/instances/jdk1.6.0/jre/lib/ext/arapi7604_build002.jar]

-----------------------------------

The first line references the 'com.bmc.arsys.arrpc.nio.ArTcpServerTransportBase' which is what was referenced in the 'java.lang.NoSuchMethodError' in the arjavaplugin.log.

We can see it is loading an ARS 7604 jar file from the JAVA installation when the ARS environment was ARS 8.1.

After removing the jar file and restarting AR Server the problem was resolved.
