I am having the Java RMI server and c++ client. I am able to pass value types successfully. But facing problem when I try to pass the Java Serializable object (which reverse map to Valuetype in IDL) containing empty java interface (which is reversed mapped to Abstract Interface in IDL). The demarshal of the Abstractbase class in CORBA is not able to handle the demarshalling of the Abstract interface which is initialize with valuetype at runtime.

The java serializable object is

public class dummyComplexType implements Serializable{

private long complexID;

private Value complexVal;

public dummyComplexType() {

super();

// TODO Auto-generated constructor stub

}

public long getComplexID() {

return complexID;

}

public void setComplexID(long complexID) {

this.complexID = complexID;

}

public Value getComplexVal() {

return complexVal;

}

public void setComplexVal(Value complexVal) {

this.complexVal = complexVal;

}

The Value above is an empty interface declared as

public interface Value extends Serializable {

//Empty interface

}

At runtime the Value is initialized with java serializeable object which is derived from the Value interface.

Note:

When I pass the Value as return type of operation then it is properly demarshaled.

On Debuging the mico I found that when Value is passed as return type of some operations it is demarshal as valuetype but when I pass the dummyComplexType which contains the Value then AbstractBase demarshel class treat it as object ref. I don’t know what is reason of treating it as object ref when actually it initialize with value type at runtime. Is it a bug in MICO in demarshalling?

Please help and guide me

Tons of thanks in advance
