Hello there,

It would be greatly appreciated if someone could help solve this issue: I'm trying to compile and run a very simple program using hibernate, ant without any containers. I've all the hibernate jar files (including dom4j-1.4.jar) in the "lib" directory and in my classpath. However, when issue command "ant run", I got the following errors: Java.lang.NoClassDefFoundError: org/dom4j/Attribute. at productInesrt.main(Unknown Source).
I definitely have the dom4j-1.4.jar file in the "lib" folder, AND "lib" is clearly in my classpath by viewing through set classpath command

Could somebody have knowledge what this message complains about? what to do to get rid of this message?

I'm using hibernate 2.1.3. DB2, ant 1.6.2.

Thanks in advance!

Do you have just the lib directory in the classpath? That won't work. You must explicitly enumerate all the jar (or zip) files in a directory. A directory in the classpath will only load class files.

I do have dom4j-1.4.jar file explicitly in my classpath, though not all other .jar files was doing the same way. Is this message complaining absense of dom4j-1.4.jar?

Try using:



Use a ';' to separate jars on Windows, ":" on Unix/Linux.

Thanks so much for replys. However, I'm using ant and "ant run" to compile and run, respectively. How does the command "java" with explicit classpath help on this? I'm not using any containers.

OK. One way or another, there is a path problem. The VM is not finding the jar files. Ant will try to construct the classpath for you. You need to check the initial paths in the ant file. Make sure that they will resolve to the right place.

What Ant file do you refer in Windows platform? Do you refer to the .classpath file? does it work for Windows? It doesn't seem to re recognized in my program.
