The spec is clear, file system access is not allowed. However, I am not
aware of any vendor who's container enforces this. I believe part of the
2.0 spec is to have the containers enforce this.
You do have choices. You could use the Connection API and construct a
connector to get the file. Or, you could pass the document to the bean. In
2.0, you could use a message bean to do this. In 1.0 or 1.1, it could be a
call to the bean. You could just parse it outside of the bean, then pass
the results to the bean.
So, there are many ways to "skin this cat". Reading directly from a file is
not one of them.

Subject: Re: Using XML Parsers inside the EJB
Hi,
Yes you are right, as per the EJB specs file access from EJBs is not
advised, but I have not found any problems in using parser from EJBs to
parse XML files. May be it depends on the app server. But I have not
implemented this kind of a solution in a production environment. May be
somebody who have done extensive XML parsing using EJBs can give more
valuable inputs.
Regards
Prince

Subject: Re: Using XML Parsers inside the EJB
Hi.
Is this really allowed in the specs? As far as I can remember file
access from EJBs is not advised. Concearning the original question -
yes, using an xml-parser should work out nicely - even though the
method might throw an IO-exception. As long as you're not accessing a
local file to read the XML (the XML might origin from the DB och an
URL).
