Description:
Symptons:
=========

While starting 2.x to 4.0 migrator utility we get the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError: com/tibco/mapper/ui/UISchemaTreeNode

Impact:
======

Loss of functionality. The following migration utilities cannot be started :
1. mbmigrator.bat  / mbmigratorgui.bat
2. mbmigrator.sh / mbmigratorgui.sh

Workaround:
===========

Add "mapper.jar" in the MB_CLASSPATH variable inside the migrator scripts mbmigrator.sh  and mbmigratorgui.sh which are located under &ltTIB_MB_HOME>/migrator/bin.

Cause:
======

The java class com/tibco/mapper/ui/UISchemaTreeNode is a part of mapper.jar which is not present in the classpath hence cannot be located.
  
Resolution:
==========

As described in the workaround.
