Hi Adi,
I think your question is clear. 
You are using the functions correctly, but you need to be sure that the
atomName is a key in the HashTable.
Please use outConne.toString() and print it somewhere visible to you,
then you are able to se what the HashTable contains.
Or you can use outConne.isEmpty
y()> ()that returns true if outConne is empty (No out connections from
the atomObject).

Hi Jesper,

1. Hashtable outConne= atomObject.getOutConnections();

2. Vector list = (Vector)outConne.get(atomName);

In the 1 statement, atomObject is the object of  type JBuilderAtom or
JBuilderModel.  What exactly I am trying to do in the above two
statements is 
1. finding out the out connections (if any) for the JBuilderAtom or
I hope this can be achieved thorough the first statement.
2. Next is getting those connections from the hash table with the name
of the above object.

I hope cleared my problem.

	Is anyone in the list know about the following problem.
	1. Hashtable outConne= atomNames[i].getOutConnections(); 
	2. Vector list = (Vector)outConne.get(atomName[i]);
	Are the above statements correct?
	I am getting null in the 2 statement. Is it the right way to
access the
	hashtable list?
