Hello,
I use d2r- update server, eclipse helios sr2, jdk6 update 24.
When i execute my java application through eclipse, it runs.
When i make a jar (Export->Runnable jar file (Package required libraries into
generated jar file)) and run it (java -jar name.jar) i get the following
error:
Exception in thread "main" java.lang.reflect.InvocationTargetException

What does it mean?? I have found that AbstractMethodError is
Thrown when an application tries to call an abstract method.
Normally, this error is caught by the compiler; this error can
only occur at run time if the definition of some class has
incompatibly changed since the currently executing method was last
compiled.
Could you help me??
Vivi.
