added new "getaccesscontrol" action for a given docid
fixed white space problem in toXML that was preventing in line end tags from being popped from the stack.
Solving the problem with relication of access file where access files were rejected from the replication servers.In AccessControlList check for serverCode is included,so only on the local server the connected user is checked for having "all" permissions on the resources specified in it...
fixed some problems with database connections getting a time out error. Also updated some catch statements
included new servlet parameter "public" specifing public read access for the submitted documentthe expected values are "yes" or "no" public parameter is optional and if it is not specified, means "no"

Added License terms to source files, added more documentation to protocolhandler classes.
closed all preparedStatement variables
implementation for multiple <resourceIndentifier> tags under <resource>
removed dependence on MetacatURL for URL handling. Added more flexible support for identifiers in the subject and object fields. They can now be just a docid, an http url or a metacat url.
fixed bug in data file permission checking. (commited wrong file last time)
- turned on the validation in order only valid xml docs comformed to the specified dtd (if any) to be submitted in metacat- with validation "on" white spaces are reported from ignorableWhitespace() callback, not from characters() (as with validation "off")...
added more documentation
changed getCookie to static
added support for the new abstract class) to handle data file uploading through metnewninterface (actuall
newninterface (actually an abstract class) to handle data file uploading through met
fixed error in logic. sending the filesize as an int terminated by a zero failed when the file size was greater than 256. The filesize is now sent as a string followed by a zero.
added support for the server to return the docid of the newly added data file. Also, now the data stream must be prefixed with the following information: filename <0> sessionid <0> filesize <0>. where the <0> symbol is a byte containing zero. The filesize is sent as an int and the filename and sessionid are sent as strings (in byte form).
unified getting "docid" value from metacat URLs specified in <resourceIdentifier> tagsby using MetaCatUtil.parseQuery() method in the same way as in MetaCatServlet.
fixed error handling and time out issues. Also fixed thread syncronization problem
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.
changed replication interface to make it easier to see the servers.
added support for one way replication
added revision support to the delete function
fixed sql error
cleaned up code
removed package doctype filtering from the resultset.
added comments to top of class
changed accession number schema to <sitecode>.<serialnumber>.<revisionnumber>. DocumentIdentifier.java parses docids into parts for easy manipulation. You can now specifiy a specific revision by asking for document <sitecode>.<serialnumber>.<revisionnumber> or you can get the newest revision by asking for <sitecode>.<serialnumber> or by asking for <sitecode>.<serialnumber>.newest.
fixed typos around acltext and dtdtext params
changed acc# generation to use db sequence instead of timestamp
commented out print statement
problems with passing the connection between objects
overwrite Jivka's overwrite
problem with passing the connection between objects
removed print statement
fixed bug where some relations were not returned because the sql did not take into account an sql that had a directory structure in it.
changed connection handling in the constructor
one more write() method was needed
constructor DBEntityResolver(Connection conn) is needed; cleared by mistake
DBEntityResolver: - added new parameter dtd for upload on Metacat file system; optional; Reader - new routines to upload dtd if provided - systemID of metadata document is used to exctract the filename of new dtd; - the new dtd is uploaded on Metacat file system as specified by dtdPath property;...
added additional actions to facilitate a web based interface to the replication servlet.
removed the initial connection pool creation step in init()
comment out line in read action that sends a copy of docid prior to returning docin XML format (apparent debug statement left in by mistake)
added replication for the xml_catalog table. Right now it is only replicated when the deltaT handler is called. I will add more replication times later.
parser for the xml encoding of the xml_catalog tableing (fi
added a logging system for replication. The log file location is set in metacat.properties
cleaned up code, added more complete documentation of replication algorithms and datastructures.
made replication on insert or update us. Also made a method in AccessionNumber public so that you can tell if an accession number has already been used.e place be
An asynchronous replication handler. This class creates a new thread to handle replication so that the user does not have to wait for replication to take place before he/she sees the result of an insert or update.
updated file locking mechanisms to use revisions instead of dates.
fixed typo, removed extra print statements
added replication_on_insert handling. Changed replication from date_updated base replication to revision number replication.
change the generation of Accession# in the form of <sidecode>.<createdate>

replication on insert functionality is now working.

Modified stylesheets and server code to use a single "read" action insteadof the earlier "getdocument" and "getrelateddocument" actions. In theprocess, developed and started to utilize a new suite of URL "protocolhandlers" that are in the package "edu.ucsb.nceas.protocols" and handle...
Added a new URL protocol handler class for the metacat protocol. Thisclass will replace the current MetacatURL class in a much simpler andextensible manner. See the documentation for java.net.URLConnection andjava.net.URL for details.
this class allows the parsing of xml data sent by a replication server to assertain document info about a remote document.
