CICS Explorer startup failing with java.lag.NoClassDefFoundError: com.mercury.ftjadin.hooks.interfaces.WToolkitHookQTJA

Question & Answer


Question

I am trying to start a new installation of the CICS Explorer and it is failing to launch and creates a error log. The workspace is not built and the launch fails. The error log shows an exception java.lag.NoClassDefFoundError: com.mercury.ftjadin.hooks.interfaces.WToolkitHookQTJA

I am unable to start CICS Explorer. What would cause this exception?

Answer

Looking at the log, the key exception is:
java.lang.NoClassDefFoundError: com.merucry.ftjadin.hooks.interfaces.WToolkitHookQTJA

This error is not specific to the CICS Explorer, but rather starting the Eclipse environment. The cause is something on your workstation has affected the Java global environment variables. The easiest way to resolve this is to tidy up the windows environment variables.

Please do the following:

  1. Right click the Computer (previously My Computer) icon from your desktop

  2. Click System Properties > Advanced System Settings > Environment Variables

  3. Locate IBM_JAVA_OPTIONS and JAVA_TOOL_OPTIONS in this list of System variables

  4. Backup the values of these 2 variables to a notepad

  5. Delete the IBM_JAVA_OPTIONS and JAVA_TOOL_OPTIONS environment variables from the list of System variables

  6. Click OK
