in order to set the validation parser at runtime
In case of:
- no DOCTYPE declaration
- <!DOCTYPE docname>
validation is turned "off"
In case of:
- <!DOCTYPE ... PUBLIC ...>
- <!DOCTYPE ... SYSTEM ...>...

reject writing DTD file if it already exists

removed descrpency between the gzipped release version of build.xml and the one in cvs

there were more mentions of DOCTITLE attr - cleared them

cleared DOCTITLE attribute in xml_documents and xml_revisions
cleared all mentions of doctitle

cleared DOCTITLE attribute in xml_documents and xml_revisions

cleared the UNIQUE constraint in xml_access - moved in AccessControlList
added FOREIGN keys for xml_relation.docid and xml_access.accessfileid referencing xml_dociments.docid

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.

Module cleanup inpreparation for a release.

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

fixed typo

included checkbox "public" for the servlet's "public" parameter
it is checked by default

included new servlet parameter "public" specifing public read access for the submitted document
the expected values are "yes" or "no"
public parameter is optional and if it is not specified, means "no"

fixed bug that was accidentally introduced when the change from metacatURL to URL was done.

added location info to catch statements

fixed comments

added comments and removed xml_acc_numbers

added precise location information (class.method) to each catch statement so that errors are more easily traced.

removed print statements

fixed typo

included implementation for public "read" access as specified from the access file

fixed introduced problem with preparedStatements

Updated build files with minor documentation changes.

Added license terms to source code files, and cleaned up some javadoc
documentation in a few places.

Added License terms to source files, added more documentation to protocol
handler classes.

closed all preparedStatement variables

Modified the license and copyright terms for many of the files. Added
a LICENSE file and a README file in preparation of a distribution.

implementation for multiple <resourceIndentifier> tags under <resource>

updated the syntax of some form parameters, put in build strings

put in build strings instead of hard coded paths to servers

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")...

changed doctype of package files

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> tags
by 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.

included "accessfileid" attr in the unique constraint

- 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

new attr "accessfileid" in xml_access table

added data port param

added the data port param

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.

added property "accessdoctype=-//NCEAS//eml-access//EN"

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: added a datafilepath parameter to show the servlet where data files are stored on the local file system.

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

Re-inserted changes from version 1.38 of build.xml that were accidentally
overwritten when version 1.39 was checked in. Now, building the protocol
handler jar file works again.

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.

added docid field to xml_relation to track which package document creates the relation.

fixed package location

changed replication interface to make it easier to see the servers.

added resource to the dtd script

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.

added build paths instead of hard coded paths

added acltext and dtdtext form fields - optional

fixed typos around acltext and dtdtext params
