Ant java task NoClassDefFoundError

I want to make a simple ant build hibernate test project. There is no error during the compilation and the build (jar).

But when I run it I get this:

  java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration ...

I have found an advise, what said : jars should be added to classpath in the command line, (classpath is ignored when the jar run from ant ... ehh), ok I tried the following:

 java -jar dist/student.jar -cp /home/myname/workspace/basic_ant1/lib/hibernate/hibernate-core-4.2.8.Final.jar

But still have the some error :NoClassDefFoundError ...

What did I wrong ?

Thanks for the replies in advance.

(org.hibernate.cfg is in hibernate-core-4.2.8.Final.jar)

-jar and -cp are mutually exclusive.

If you want to use java -jar then your main JAR file needs a Class-Path entry in its manifest that points to all the other jars its Main-Class requires (the manifestclasspath task is a handy way to generate this value).

If you use java -cp then you have to give the main class name on the command line, the Main-Class from the manifest is ignored.
