How can I use groovy joint compilation with eclipse ide v3.3 or 3.4?

Hello,

How can I use joint compilation with Eclipse IDE v3.3 or 3.4.

I am asking because Programming Groovy states that mixing both Groovy and Java code is allowed, although other authors suggest compileing Java src to the bin direcotory and Groovy src to bin-groovy directory, the default for GroovyEclipse plugin.

When I compile to the bin and bin-groovy directory, the imported, calling any compiled groovy class from a java class results in a ClassNotFoundException. How can this be corrected.

I am pretty sure that the Eclipse plugin has issues as it beta. I would guess that the groovy-bin needs to be on the same classpath as the bin.
