I want to profile a web application running on JBoss with Eclipse and TPTP. I start the server in profiling mode, a new Profile On Server window is displayed but a Problem occured : An internal error occurred during: "Fetching children of data collector". java.lang.NullPointerException Then I can't configure the Profile Settings and must close the Profile On Server window.
