Passing Variables across stage in OSB

Question

Hello All,
I am using OSB 11g and I am new to this, for my project I have created a proxy service where in the message flow I have created a conditional branch, within that I have given pipeline->stage->assign. In Assign, I am assinging an expression value to a new variable created for that Assign. I need to use this variable outside the stage and branch for another branch activity. Is it possible to make this variable accessible to activities outside the stage and branch??
Is there any other better method to create variables which can be used across the message flow...like how we use in BPEL.
Please guide me to proceed with this...

Answer 1

Can you let us know your use case? If your message flow starts with a pipeline pair and in that pipeline you declare a var, say myVar and after that pipeline you have a conditional branch then in the each and every branch you may access that variable (myVar). If any of the pipeline in any conditional branch defines it's own myVar then the local myVar will override the global one.
Can I use the variable outside the pipeline or will the variables be accessible only within stages of pipeline??When you say outside, then what do you mean by that?
