XQuery from EJB - Can't load file

Hi, I am trying to do something very basic and am a novice: I am running the
following code from an EJB:
-------------------------------------------------------------------------- 1.
Configuration config = new Configuration(); 2. StaticQueryContext staticContext = new
StaticQueryContext(config); 3. DynamicQueryContext dynamicContext = new
DynamicQueryContext(config); 4. XQueryExpression exp =
StaticContext.compileQuery("doc("/myFolder/myFile.xml")/users/user");
5. SequenceIterator it = exp.iterator(dynamicContext); 6. List users =
(List)exp.evaluate(dynamicContext);
-------------------------------------------------------------------------- This gives me
the list of all users in the file. However, since file i/o is not allowed from within
EJB, I get the following exception on running the code. (The exception occurs in line 5)
<b> net.sf.saxon.trans.DynamicError: java.io.FileNotFoundException:
\myFolder\myFile.xml (Access is denied) </b>

I'm sorry, I don't know much about EJB. If you want to run a Saxon query in an
environment where file I/O isn't allowed, then you'll have to find some way of passing
the source document and the query across as objects in memory - either as lexical XML in
a stream, or as a pre-built tree in memory.
