Following maintenance update 6.3.2.09 the Livehealth applications (Live Exceptions, Status and Trend) fail with the following message.

HTTP Status 500 - Unable to compile class for JSP:

type: Exception report

message: Unable to compile class for JSP:

description: The server encountered an internal error that prevented it from fulfilling this request.

exception: org.apache.jasper.JasperException: Unable to compile class for JSP:

 

Check and make sure that the $NH_HOME/web/lib folder has only one "ecj" file

There should be ecj-4.4.jar file and no other ecj*.jar files.

Remove any extra ones,if that is the case, by doing the following

  1. Stop the Tomcat Service
  2. Move the file to anywhere else (where it is not found), leaving the ecj-4.4.jar file in place
  3. Start the Tomcat Service.

 

Live health applications should then start, without error
