Metacat

problem with passing the connection between objects

removed print statement

fixed bug where some relations were not returned because the sql did not take into account an sql that had a directory structure in it.

changed connection handling in the constructor

one more write() method was needed

constructor DBEntityResolver(Connection conn) is needed; cleared by mistake

DBEntityResolver:
- added new parameter dtd for upload on Metacat file system; optional; Reader
- new routines to upload dtd if provided
- systemID of metadata document is used to exctract the filename of new dtd;
- the new dtd is uploaded on Metacat file system as specified by dtdPath property;...

added additional actions to facilitate a web based interface to the replication servlet.

removed the initial connection pool creation step in init()

comment out line in read action that sends a copy of docid prior to returning doc
in XML format (apparent debug statement left in by mistake)
