NoClassDefFoundError with message-driven bean

[bjoern.eilers]

Hi!

I have deployed a message-driven in JBoss 4.0.3RC1 whose onMessage() method creates an instance of an utility object that I have deployed within the same JAR file as the MDB. However, whenever I send a message to the Topic that the bean is listening to, I receive a NoClassDefFoundError saying that the class describing this utility object cannot be found.

Is there some configuration in ejb-jar.xml, jboss.xml or the MANIFEST.MF I have to set?

Thanks and best regards,
Björn

Post the stacktrace. NoClassDefFoundError is thrown when the classes referenced by a class are not found in the classpath

Sure, here it is:

The class(es) referred by gruppe00/clairline/CLAirlineServiceLocator, through the import statement or through the extends statement or through someother means are not there in the classpath. Make sure that all the appropriate jars/classes required by this gruppe00/clairline/CLAirlineServiceLocator are placed in the classpath

[bjoern.eilers]

Thanks for you help - it was a JAR file that was missing from the classpath.
