OK, this is an intermediate information for everybody who is interested how this story is developing.

Well, I actually didn't want to work on this during my trip, but it was itching too much. After updating JBoss on my notebook, I was kind of successful (Yipppieee!!!) - partly at least.

The problem seems to be ClassE. If I do the following changes, everything works just fine:

@Embeddable
public class ClassE
 implements java.io.Serializable {

 private int classEVar; // --> private String classEVar

 public ClassE() {
 }

 public ClassE(int classEContents) { // --> public ClassE(String classEContents)
 this.classEVar = classEContents;
 }

 public int getClassEVar() { // --> public String getClassEVar()
 return classEVar;
 }

 public void setClassEVar(int classEVar) { // --> public void setClassEVar(String classEVar)
 this.classEVar = classEVar;
 }

And now variable access with

#{classAInst.classEInst.classEVar}

works without errors. Input, output, everything works fine like this, no problems at all.

Don't ask me, right now I've no clue why it makes such a difference if I use a String instead of an integer.
