Java Enterprise java bean & Java EE (EJB): XML in Session Beans

I am currently researching the design for an EJB component. One of the stipulations is that the processing of an XML document must occur on the server; however, I noticed the EJB specification forbids the inclusion of java.io.* symbols in session beans. Does anyone know of a work around?

How does this pose a problem for processing XML?

empyrean,

One more thing...

Thanks for joining JavaRanch, but could you take a quick look at the naming policy and edit your profile accordingly.

Namely reading XML from a file. I probably should have stated that my problem has more to due with handling IO in session beans and less to do with the actual processing. BTW, thanks for redirecting me to the naming policy.

Where is this file located?
You can still ask your classloader to get an InputStream of a resource (file) located in your classpath.
You can still use a Client Socket to retrieve whatever resource via network.

Using file IO directly is still possible, if the AppServer allows it. But it's considered as bad practise, because it reduces the portability of your EJB. But if you don't care about portability simply test it, it might work.
Hmm, I shouldn't propagate bad practise
