Metacat

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....

Updated the readxml shell script to use the new DocumentImpl class instead
of the old DBReader class.

Removed DBReader.java because the functionality of that class has been
replaced by the more efficient DocumentImpl class.

Created new class "DocumentImpl" which represents an XML Document. This
document will eventually implment the DOM Document interface. For now,
it implments all of the functionality that was present in DBReader, plus
cuts down on the number of database calls required to read a document. And...

Added script to register document types in the xml_catalog table for our
common public ID's.

Added install feature for copying dtd's to the servlet directory so that
they are accessible to the metacatservlet.

Added new utility query to return all of the xml_nodes info for a given
document id in metacat.

Updated documentation for NodeComparator.java.

Modified the DBReader and ElementNode classes to more efficiently read
documents from the database. In the old implementation, a db connection
was opened for each and every node in a document, recursively fromthe root
node. In the new implementation, all of the data from xml_nodes is...

redirector to access the marine servlet

modified the xsl to work with the new servlet architecture.o

marineServlet now overrides the transformQuery() function to allow it to put the values back into the text boxes of the xsl stylesheet rendered form.

-fixed the bug where a pathquery document was not valid inside of the <query> tags in a resultset document.
-provided override support for a new function called transformQuery() which allows specific applications to
customize what is returned in the <query> tag

Fixed small bug in transforming the document to HTML. If there was
no stylesheet for a given doctype, and so the transformation couldn't
occur, the XML doc was returned, but the content-type was still set
(incorrectly) to html. Now it is not set to text/html when an xml doc is...

removed extraneous protected tags and replaced them with private tags

Modified behavior of handleSQuery() to now send the resultset document
back to the client application -- this was a bug introduced by recent
changes to the servlet. Also, generally cleaned up the servlet to
produce cleaner documentation and removed some extraneous code and remarks....

decrease the number of "initialConnections" to 5, "increaseConnections" stay 5, decrease the "maximumConnections" to 10

Changed release to version to alpha 8 (1.0a8) and tagged metacat in
CVS as METACAT_ALPHA_8

Updated default html forms for metacat queries to use the "anyfield"
keyword for constructing a default query. This should now work with
the new handleQuery method of MetaCatServlet.
BugID:
Submitted by:
Reviewed by:

changed to work with the new MetaCatServlet model. marineServlet now only overwrites one method in MetaCatServlet.

changed the prototype of overwritable functions to "protected" instead of "private".

change the resultset format for DataGuide

Changed the flow of query and SQuery. SQuery now only handles a preformatted pathquery document as input (in the "query" parameter).
HandleQuery now handles all structured queries derived by CGI parameters.

Made changes to createSQuery to allow for multiple parameters of the same name. Also changed the param list to include only "Hashtable params" without a "String doctype" since the doctype is already contained in the params.

fixed bug with handleSQuery() that kept DMan from access the squery functionality

- created transformResultset() which transforms an xml resultset document and displays it to the client useing DBTransform
- renamed transformDocument() to createResultDocument() and modified its functionality to only return a restultset xml document
- changed handleSQuery() and handleQuery() to use the new methods

Changed "xmltodb" to "html-path/style" so that the resultset.xsl
stylesheet could be found in various servlet contexts.

changed release version

Modified binaries to change classpath for metacat.jar under new
build process.

Repository reorganization, and some file cleanup to make the XSL and CSS
files portable to various installations of metacat (by using the
build.xml file substitution in the XSL files). Removed "xsqltest" directory
because it is no longer needed. Created new "style" directory inside of...

removed unneeded replace command

Added user and password to build.xml for filter substitution.

remove handleQueryAction() in favor of directly calling handleQuery() and handleSQuery() from doGetOrPost()

Cleared hardcoded paths for the location of .html files and use
the new "htmlpath" property from metacat.properties file

sorry, I needed new property "html-path" with value "/xmltodb" for me.
Chad, for you should be I think "/berkley"

New "servletpath" and "installdir" properties

Set a filter for installdir property

set filtering="yes" attribute on the copy command of metacat.properties

Added decodeMouseAction(Hashtable) to decode the mouse click action outside of handleGetOrPost to allow for easy modification of images in a different application.

added new constructor to allow the creation of a metacatutil object that uses a properties file other than edu.ucsb.nceas.metacat.metacat.

Fixed build.xml bug -- jar file was included recursively in itself, causing
ever-growing size of jar on install. Changed location of jar file that is
built (from build.dest to build.dir) to fix the problem.

added eml-resource to the catalog

Broke up handleQueryAction into handleQuery, handleSQuery, runQuery and transformDocument. handleQueryAction is now a base function which makes calls to each of these functions to create, run and transform a query from CGI parameters.

Added createSQuery() to handle structured queries of an arbitrary number of parameters. Also modified createQuery() to handle a null query in a graceful manner.

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

Updated build process to now use a copy of the source files so that keyword
substitution can ocur before the build. This allows for substitution of
hardcoded values into the source before the compile. Currently, I am
using this feature to do the following:...

added Logout link

added Logout handling

clear lib dir from paths like xmltodb/lib/something.html

on "DELETE" added delete from xml_index table for a given docid
before delete from xml_documents, b' of foreign key in xml_index(docid)
to xml_documents(docid)

Changed exception handling mechanisms for DBReader

added createSQuery

broke up handleQueryAction into handleQuery, handleSQuery, runQuery and transformDocument

-Reorganized xmltodb module to support new install process for the new
linux server (dev.nceas.ucsb.edu). Added "build.sh" shell script that
calls ant withthe proper umask set for installation. Use:

./build.sh install

to post a new copy of the servlet and its supporting files to the install...
