Integration

I receive a PDF as input to my BPEL process in base64Binary format. I have to convert it back to PDF and post it to a folder. I tried applying this code in 'Java Embedding' process, but is not working. Can you please take a look and suggest what am I doing wrong?

I am able to compile the code successfully but it gets stuck at java_embedding process during runtime.

Thank you.
