resolveEntity and systemId question

[Kelvin Lawrence <kl...@us.ibm.com>]

Sorry if this has been asked before but I would appreciate an answer.

Even though I do make sure I set the system ID before calling the parser,
when I parse XML files that refer to a Schema, and my resolveEntity method
is called, the value of systemId is just the file name (not a full URL with
a path). However, if the XML file uses a DTD file, then when resolveEntity
gets called I get passed the full URL of the form
file:///mypath/mydir/myfile.dtd . Is this a Xerces bug or am I probably
doing something wrong in my code. Seems that regardless of whether I am
dealing with DTDs or Schemas that my code should be passed the fully
qualified URL to the "schema" as the parser has that information available.
Without this I have to try and figure out in my own code where the schema
is even though the parser knows where it is.

Thanks
Kelvin

I think that this is a bug in XMLValidator. We should expand path for
schema file before calling user's EntityResolver. The proposed patch is
attached. 

Eric, can you, please, confirm that this is a right thing to do?

Thank you,
Elena
