Hi ,
(1) i am performing M2M transformation(bpmn to bpel).
my sample MetaModel for bpmn is following.

filename: bpmd.ecore
----------------------
BusinessProcessDiagram
Pools :Pool
Name : EString

Pool
Process :Process
Name :EString
Process
Name : EString
GraphicalElements : EObject
Task
taskType : TaskType

whers TaskType is XSI type Data

(2) and my model input file is following.
bpmnModel.ecore
----------------
<?xml version="1.0" encoding="ASCII"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:bpdm="http:///bpdm.ecore">
<bpdm:BusinessProcessDiagram xmi:id="_tLfiYJVvEdusYsgvXrrVmQ">
<Pools xmi:id="_45T0YJVvEdusYsgvXrrVmQ" Id="_uqHcgJVvEdusYsgvXrrVmQ"
Documenation="New Document" Name="Pool">
<Process xmi:id="_45T0YZVvEdusYsgvXrrVmQ" Name="Process">
<GraphicalElements xsi:type="bpdm:Task"
xmi:id="_45T0Y5VvEdusYsgvXrrVmQ" Id="_wQouYJVvEdusYsgvXrrVmQ"
Pool="_45T0YJVvEdusYsgvXrrVmQ" Name="task1"/>
</Process>
<lanes xmi:id="_45T0ZpVvEdusYsgvXrrVmQ" Id="_uqHcgZVvEdusYsgvXrrVmQ"
Name="Lane" parentpool="_45T0YJVvEdusYsgvXrrVmQ"/>
</Pools>
</bpdm:BusinessProcessDiagram>

(3) my ATL file is very simple it is only print name of
BusinessProcessDiagram .
module bpmnSeq2bpelSeq; -- Module Template
create OUT : BPEL from IN : bpdm;

rule bpmnSeq2bpelSeq {
from input : bpdm!BusinessProcessDiagram
do {
input.Name -> println();

}
}
but when i run this program it generated following error .
An internal error occurred during: "Launching".

java.lang.NullPointerException

at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58)

when i removed <GraphicalElements> entry from bpmnModel.ecore so it
works fine. but i don't why it is not wworking with <GraphicalElements>
tag.

pls help me.
thanks in advance.

Hi,

I suppose the problem is not in launching the transformation
programmatically, but in loading the model, which led you to refocus
your question in another post. Right?

Let us first solve the loading issue. We can come back to the launching
part later if there is also a problem there
