I tried to run the following (this is from an example posted on Sun Java web site). The SQL statement simply creates and populates a few table. java -classpath %J2EE_HOME%\lib\cloudscape\tools.jar;%J2EE_HOME%\lib\cloudscape\cloudscape.jar;%CPATH%;%J2EE_HOME%\lib\cloudscape\RmiJdbc.jar;%J2EE_HOME%\lib\cloudscape\license.jar COM.cloudscape.tools.ij RMS.sql It gives me this error, Exception in thread "main" java.lang.NoClassDefFoundError: COM/cloudscape/tools/ij Should I install Cloudscape database (jar file?)to make it work? Doesn't it come standard with J2EE SDK? I do have j2sdkee1.3.1 installed, although I don't see this specific class file. Any suggestions?
