If you're using the Websphere 5.0 UTE in the Rational Application Developer 6.0 and you want to create a cloudscape 5 database with the cview tool you may get a 'java.lang.NoClassDefFoundError: com/ibm/db2j/tools/cview' - Error while starting cview.bat
To avoid this error search for a batch file called setupCmdLine.bat in the bin directory above. Open this file with an editor and add SET CLOUDSCAPE50_HOME=%WAS_HOME%\cloudscape50
under SET WAS_HOME=C:\Programme\IBM\Rational\SDP\6.0\runtimes\base_v5
