Hi,
Thanks a lot for response.
Yes, I have a map of filename as indexes and their value is parsed dom object
for xml. This problem "File not found " exception is coming intermittentely.
Please find the attached files for our resolver and transformer code.
Resolver.txt is our implementation which get called from transformer.
XML_TRANS.txt is the file where we implement XML transformer.
We are trying to re-produce but the problem is not occuring in development. It
is happening in PRODUCTION intermittently.
Could you please take a look on these files and can point something which could
lead this problem.
Regards
Ajay

First obvious question: You say you have the document in a Map; I presume you
mean a Java Map indexed by the filename. Xerces and Xalan won't look there
unless you have plugged in a user-written Resolver which recognizes the URI you
are requesting and retrieves the document from the Map object rather than the
file system or network. I'd suggest setting a breakpoint in that resolver to
check that it's doing what you think it's doing.
Note that what the resolver sees *is* a URI, not a filename, so you may need to
use the file:// "scheme"; otherwise, a filename will usually be interpreted as
relative to the enclosing document's base URI. Again, having the debugger stop
in the resolver will let you see what's actually being passed to it, so you can
change either the call to the document() function or the resolver's logic as
appropriate.
If those suggestions don't solve the problem for you, post more specifics --
exactly what the resolver you've written looks like, exactly what the Map's
keys are, exactly what the URI passed to the document() call looks like. We
need to know exactly what you're doing before we can offer specifics.

Okay. So you should have asked this question on the Xalan user mailing list.

Better ask the Xalan folks and they'll probably need more context (e.g. stack
traces, code, etc...) to be able to tell you what's going on.
