Hi,
if i could get some examples of reading the XML and sending the xml back to the calling program.What kind of process do you want to perform on the input XML?
You said "reading", but for what purpose? Storing data in the database, or just transform the XML into another form?
Anyway, you'll probably need a function, something like :
create or replace function processXML (inputXML in xmltype)
return xmltype
is
  outputXML xmltype;
begin
-- process inputXML here, and construct outputXML
return outputXML;
end;Back in Java, you can use the oracle.xdb.XMLType class to map the XMLType SQL datatype to a Java object and manipulate it.
