I’m using tomcat to run a web application. Without any projects added to my Tomcat v6.0 Server at localhost, I start the server and an exception is being thrown. It says there isn’t a mapping for class sun.awt.AppContext I’m using jre6 as my runtime. I have my JAVA_HOME environmental variation set to the jre6 folder and I have Eclipse set to the same one. Do you know why I am getting this exception and how to resolve?

Here is my stack trace:

    I’m pretty sure your problem is HP QuickTest.

    HP QuickTest sets up JVM options which modify the java bootclasspath – nasty.

    I’m not sure exactly how it works, but I’m guessing that it sets an environment variable JAVA_OPTS (which is picked up by Tomcat’s startup scripts)

    3 options (first is definite, second & third are based on my guess above):

    1. Try uninstalling HP QuickTest
    2. Open up bin\catalina.bat inside your Tomcat installation, and try resetting JAVA_OPTS at the start of the script.

    Something like this:

       echo "Current JAVA_OPTS (resetting to ''):"
   echo %JAVA_OPTS%
   set JAVA_OPTS=""

    3: Or, try setting JAVA_OPTS variable (to empty string) in your Eclipse server startup dialog
