Metacat

A public method named getZippedPackage() and other relative private methods were add to this class. The public method can give a zip output stream if a docid and other parameters were passed to it.

A property named "morpho" was added. It is the path for morpho.jar. (Now, in DBQuery class some morpho package class are used). Morpho was added to cpath too. During the "install", morpho willbe copy to the target too.

In QBQuery class some classes - Triple and TripleCollection, which come from morpho package wereused. So morpho.jar was added to metacat libray. The reseaon to use these class is xml document need to be parsed and get docids' relationship.

Adding the style sheet of html file in zip data package for morpho to metacat.
So the html summary file can have the same style in morpho and metacat zip package.

Adding a new doctype and its publicid="-//NCEAS//eml-generic//EN".
It connects http://server@style-path@/generic-morpho.xsl.
So the html files in zip data package have the same style sheet for both morpho and metacat.

Some code format problem was fixed.

The bug was fixed.
After a referral exception happend, we should set enviroment properties again before creating a contex. These environment properties include PROVIDER_URL, SECURITY_PRINCIPLE, SECURITY_CREDENTIALS, REFERRAL, and INITIAL_CONTEXT_FACOTRY. Otherwise, you couldn't get a naming exception.

Removed an obsolete filter fromthe build.xml file.

Updated installation instructions to reflect the new procedures involved
with the changes to build.xml.

Modified the build.xml file to make it easier to set up the configuration.
There is now a "config" target in which all of the properties that are usually
modified are located. Also, now one sets the location of tomcat and the
webapps dir, and chooses a name for the tomcat context, and everything else...
