Problem with file URI for external DTD

Question

Hi All,
I am getting UnknownHostException when i am trying to parse an XML data as InputSource
to parser.
The exception is thrown while to trying resolve file uri
set for inputsource to locate DTD.
The code works fine in of the Solaris machine but it throws this exception in
one particular machine (solaris again). On both Weblogic6.0 with SP2 is running.
The host "local" it says Unknown is infact a directory.
I am unable to figure what is wrong. Please let me know asap the reason and if
there is any solution.
I am attaching the piece of Code and the Exception stack trace.
thanks
ashok
