Metacat

storing user_owner and user_updated where needed
new function in DocumentImpl checking for "write" perm on UPDATE or DELETE
added delete from xml_index of the old version of docid on UPDATE

Continued code redesign for the DocumentImpl class. Now the "delete" and
"write" methods are static, so a DocumentImpl objject need not be created
in order to initiate a INSERT, UPDATE, or DELETE action (it is created
implicitly by the DBSAXHandler). When doing a "READ" action, one still...

Folded the functionality from DBSAXDocument into the DocumentImpl class.
Now DocumentImpl handles both the reads and the writes to the database.
Eventually, it will implment the full DOM Document interface. Eliminated
the DBSAXDocument.java file as it is no longer relevant....

Added "release" keyword to all metacat source files so that the release
number will be evident in software distributions.

Call to DBSAXNode constructor simplified

Fixed bug in DBEntityResolver so that it now properly delegates to
the system id found inthe database.
Changed DBValidate to use DBEntityResolver, rather than the OASIS
catalog, and to return validation results in XML format.

Fixed bug where TEXT nodes couldn't be longer than 4000 characters, which
is the maximum length of a VARCHAR2 field in Oracle. Now, if text
exceeds the field length, I break the text up into a series of TEXT
nodes each of the max field length, and the remainder in the last...

Fixed bugs associated with the new UPDATE and DELETE functions of
DBWriter. There were problematic interactions between some static
variables used in DBEntityResolver and the way in which the
Servlet objects are re-used across multiple client invocations....

Merged in substantial changes to DBWriter and associated classes and to
the MetaCatServlet in order to accomodate the new UPDATE and DELETE
functions. The command line tools and the parameters for the
servlet have changed substantially.

Fixed bug in DBWriter using the new SAX2 interface. Turned out it was a bug in xerces-1_1_1, which was fixed by Andy Clark after I reported it.

1) Simplified database connection creation by adding new utility routine in MetaCatUtil that reads configuration information from the properties file.
2) Created MetaCatUtil.getOption() to retrieve options from properties file.
3) Unified SAX Parser creation by specifying parser driver in the properties file and dynamically loading it using the XMLReaderFactory interface....
