ramnivas - many many thanks smilie
Hi folks,

I have a problem and hope you can help me!
I just start with AspectJ and AOP in general and coded a really simple example. When I run it, I get the following error message:

java.lang.UnsupportedClassVersionError: HelloAOP (Unsupported major.minor version 49.0)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:539)

at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302)
Exception in thread "main"

I assume it has to do with an incompatibility between my Java, Eclipse and AspectJ versions...
I use the following:
- Java 1.4.2 (Is a must, because the customer needs 1.4.2)
- Eclipse 3.2.0
- AspectJ Development Tools 1.4.1

Which Eclipse and AJDT do I have to use to geht AspectJ going with my Java 1.4.2 ?

Thanks for your help!
