You may need to add this option when trying to run the jar file
-javaagent:"C:\Projects\spring_lib\org.springframework.instrument-3.0.5.RELEASE.jar"
the jar file may be located in another folder so put in there where it is located.
In case you are using netbeans
ide, that's what's exactly why I put in for VM options on Run on Project Properties. Let me know if this helps. Thanks!
