Process SOAP Message with attachments

Hi,

I want to process a SOAP message which has attachments. Basically i am getting this message from the XI system. The SOAP body has two parts content and a PDF file(as an attachment).

I have to read this SOAP message in a webservice and save the PDF file.

I am not getting how should i design my EJB so that it is able to receive both the content and attachment.

Please give your suggestions.

Regards

Sidharth
