Metacat

Converted some java 1.5 code to java 1.4 code. Removed usages of "String.contains()", "Node.getTextContent()" and "Node.setTextContent.
Wrote two new methods: 1) getTextContent, and 2) setTextContent, to emulate the org.w3c.dom implementation that ships with java 1.5.

Seperated web API code, from plain java code, by creating seperate constructors and handling Http stuff in just two methods: "clientRequest" and "handleDownloadResponse".
Results in using HttpServlet code in an isolated/thin layer, making it easier to test and reuse all other methods.

Added new functionality for action="Set Access". Includes methods handleChangeAccess, setPublicAccess and getNodeTextStack. Also, cleaned up some code as a result.

Modified string constant "SUB_DOCS_PATH" to be static and public accessible.

Grant the public read access to the data files, if it was done for the metadata file. Also cleaned-up some debug statements.

Fixed 3 bugs:
1) If there is a call to this class without an "action" (i.e. the initial time the login form is loaded) a null pointer exception would be thrown.
2) If the user logged out, and then tried to query, the server would send an error (invalidated session)...

Created method "private void download(ClientView bean, HttpServletResponse response)", along with several other additions to support downloading.
Includes functionality for FGDC-related package downloads (zip file) and individual data file downloads, with original filenames.

Created new XPath constants for FGDC queries.

Modified the "clientDeleteRequest" method to handle meta-file deletes.

Clear the bean's "action" property after most operations are complete, in case user refreshes the browser (it won't repeat). Modified "delete" code, and "handleFileUpdate" method. Added new methods: getStringFromInputStream and makeRedirectUrl.
