Metacat

A new action named export was add to it. This action will export a zip output stream for a data package. In the zip output stream, meta data documents, data files and a html summary file are include. The stucture will looks like:
package----/metadata/metadata docments...

Two metacat util methods were add. One is getDocIdFromString and the other is getVersionFromString. They output a docid and revision if a string like str1.str2.str3. were passed to them.

A method named transformXmlDocument were overload. It transform an XML document to StringWriter using the stylesheet reference from the db.

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.
