java.lang.NoClassDefFoundError running from a jar

OK, this should be trivial, but is driving me crazy.  I have an app that I built and tested in Eclipse. I then exported to a jar file.  This app depends on a set of other jars, such as xbean.jar.  So, I created a .bat file to run it:

set CLASSPATH=xbean.jar;xbean_xpath.jar;xmlbeans-qname.jar;RebalanceCalculator.jar;maprResultsXmlBeans.jar;maprPortfolioXmlBeans.jar;maprModelXmlBeans.jar;maprConstraintsXmlBeans.jar;.;jsr173_1.0_api.jar;
java -jar MaprXmlCmdLineClient.jar %1

When I run this bat file from a command line, it starts fine, but as soon as it references anything in another jar, I get a NoClassDefFoundError!  I have checked and this "missing" class is in the xbean.jar file that is in my CLASSPATH for this command prompt window.  

Any ideas what is causing this?!  Thanks...MarkStart Free Trial
