The following error message:

Your instrumented application could not find the Clover classes necessary to record coverage. Please use the 'Run with Clover' option to correct this. (class java.lang.NoClassDefFoundError:com_cenqua_clover/CloverVersionInfo)

means that Clover classes were not found at runtime.

You have to either:

a) put clover.jar in Tomcat lib directory (TOMCAT_HOME/lib)

or

b) point to clover.jar location during Tomcat startup (e.g. by 'set CLASSPATH=/path/to/clover.jar' in TOMCAT_HOME/bin/setenv.bat)

or in case you run server from Eclipse

c) choose "Run with Clover as ..." option (instead of "Run as ...")
