No line before this.. This is what all eclipse display the error.
"at ..." is a line from a stacktrace but it's not the start of it There
is more - if Eclipse is not showing it, change the console settings.
My guess is that is says the trace below. Please try the suggestions
already made.

I think "Maybe Module.owl is OWL syntax, not RDF", this is right..

2.13 is jena version.. I have not placed the Inputstream code in
try/catch
block, is it the problem?
No idea. There isn't enough information; all this email thread says
so
far is "there's an exception".
Maybe "in" is null (=> not found)
Maybe Module.owl has a syntax error in the RDF/XML
Maybe Module.owl is OWL syntax, not RDF.
If Module.owl is a file and not a Java resource, then
RDFDataMgr.read(model, "Module.owl", Lang.RDFXML) ;
is simpler and more direct

Hello, what is the problem with this code.. I can not understand
even
the
error message by eclipse.
What is the error you are seeing?
(it's missing a closing "}" for start; if this is jena3, then the
imports
are wrong - but Eclipse will sort that out with shift-cntr-O)
