I am working on an application in which I made web service which produces reports in .pdf format and I have made a J2ME client for that as well. How can I view the .pdf format reports in J2ME. I am using the Base64 conversion for the data transfer from web services to J2ME client.
You can't. PDF is a very complex format and needs a complete application to be readable, not just some library code. Some devices come with PDF readers - including my latest phone. Many do not.
Actually, I don't like PDF on pocket-sized mobile devices, because it can't adjust the viewable space to fit the smaller screens of pocket mobile devices. It's like trying to read a book through a keyhole.
