Metacat

multiple files with the same names no longer overwrite each other.

fixed minor error

added support for data file upload via a random, authenticated socket.
The action added to metacatServlet is getdataport. A client can send a getdataport request. the server returns a random port number and starts a thread to handle the request on the given random port. The thread will only accept requests from the client that has the session id equal to that of the user that made the getdataport request. the user must be authenticated and logged in to make a getdataport request. Once the port number is received by the client the connection can be made. The first two parameters in the data stream must be the filename, followed by session id. (note that it only wants the session id not the whole cookie and the "JSESSION=" must be stripped from the text.) If the session number is correct, the upload is allowed, the file is written and xml_documents is updated with the new data file information.

added support for data file upload via a random, authenticated socket.

- appling acl through access files only
- clearing around update/delete of access files - to delete the related records from both xml_access and xml_relation tables
- included check for user permissions for setting acl on the resources in the access file
- moved RelationHandler.deleteRelations(docid) down in RelationHandler obj just before the write of the new relations

fixed url error in data download function

Use the new property "accessdoctype" to check if this is access file.
If it is, run AccessControlList for wirting into xml_access and xml_relation tables.
This is the thread that writes XML Index but afterwards.

included support for submition of access files
+ storing the acl info in xml_access table and relationship records in xml_relation table like
<aclfile, "isaclfilefor", recourceIdentifier> for every resource included in the access file

added support to download a data file through metacat using a metacat url or a docid parameter.

updating a package file now updates the relations that are created from it. Also, if you delete a package file, it will delete the relations associated with it.
