Description: 

JMX and PMI metrics lost due to WebAppSupport.jar not being a legal extension.

 

Issue:

After configuring JMX and PMI metrics, the following error appears:

[ERROR] [IntroscopeAgent.Agent] Candidate jar file /was/v7r0/whcell/whnodea/AppServer/wily/core/config/../ext/WebAppSupport.jar is not a legal extension: com.wily.util.extension.InvalidExtensionException: Extension_Invalid_Jar_File_Message[/was/v7r0/whcell/whnodea/AppServer/wily/core/config/../ext/WebAppSupport.jar]

 

Solution:

It is highly likely that the current WebAppSupport.jar file is corrupted and needs recopying.  This can be done a few ways:

1. If having the Agent installer, then install again to a temp directory and copy the new WebAppSupport.jar over.

2. If having the Agent no-installer, then unzip the files and copy over the new WebAppSupport.jar file.
