Integration

Hi all, I am still very new in this so I hope you guys can help me out. Ok so I got SOA suite installed pointed to my db. Now what I need to achieve is to design a esb service that basically parse an edi file to xml format.

I tested those adapters came with the suite namely file, ftp, jms, soap etc.. Those work great but none can solve the issue of converting an edifact file to a xml file so I search around for solution but there are so many things in oracle otn. I am so darn confused.

Can someone please help me step by step on what to download or install at the minimal to achieve my aim? thank you in advance
