#4390 [HHQ-4255] WebSphere Plugin error: Plugin class not found: c

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4255
WebSphere Plugin error: Plugin class not found: com.ibm.websphere.management.exception.ConnectorException (invalid classpath or corrupt plugin jar).

After installing a hq-agent on the server running WebSphere Application Server, setting the configuration properties yields:


The configuration has not been set for this resource due to : Invalid configuration: Plugin error: Plugin class not found: com.ibm.websphere.management.exception.ConnectorException (invalid classpath or corrupt plugin jar)

The agent.log reports:


Plugin error: Plugin class not found: com.ibm.websphere.management.exception.ConnectorException (invalid classpath or corrupt plugin jar)

Expected Result:


After setting configuration properties for WAS, the settings are saved and availability/metrics begin collecting.

Actual Result:


Unable to set configuration properties for WAS; no availability/metrics can be collected.

Steps to Reproduce:


1. Install hq-agent on platform running WAS.


2. Log into Hyperic


3. Import auto-discovered WAS platform into inventory


4. Selected newly added (step 3) platform resource


5. Select Inventory tab


6. Click 'Configuration Properties' link or Edit button within Configuration Properties section


7. Configure admin.port, admin.host, username, and password


8. Click OK button


9. Note the reported error:


The configuration has not been set for this resource due to : Invalid configuration: Plugin error: Plugin class not found: com.ibm.websphere.management.exception.ConnectorException (invalid classpath or corrupt plugin jar)

Work around:


None

Additional Information:
