Metacat

code to handle null pointer exception

Added query for indexing attribute - needed for indexing packageId

Eliminate hard-coding of the knb context from the advanced search code. Advanced search servlet determines the metacat context name by reading the metacat.properties file at servlet initialization.

Reformatted LSID code for consistency.

Added apache commons logging to the LSID servlet using log4j. Remove println statements.

bugfix so that getlastdocid works for postgres

fix for the access control check - earlier only permission 4 and 7 were checked for read. Now the query checks for permissions 5 and 6 also

Modified code to that isModerator param is passed to the xsl which will render the results.

Changing the table name back to xml_index

Minor change to diagnostic output.

Fixed a log bug.

Modify the bean's get() methods that return String values to trim white space off the string prior to returning it. This is so that input fields that contain only white space will not be treated as valid search values.

Cleaned up AccessionNumber class to get rid of unused methods. It seems the entire accession_number table is no longer used but has not been deleted from the build. Will do in subsequent commit.

1. Modified buildIndex() so that only one connection is used for both indexing nodes and indexing paths.
2. Modified the indexing algo so that indexing of paths is done while nodes are being indexed. Results in a much faster indexing algo
3. Replaced access to NodeRecord.<variable> with NodeRecord.<getVariable>

Change the maximum code level reported to the site contact from "info" to "notice". This is to reduce the amount of diagnostic output generated in the email reports to the site contact. Diagnositcs of type "error", "warning", and "notice" will be sent to the site contact, while messages of type "info" and "debug" will not (but they will still be sent to the Harvester Administrator).

Modified the way checkDocumentTable is accessed. Also removed the while loop from the checkDocumentTable. Now if the document is not found, the thread goes to sleep - instead of checking again. (In hope of a more bugfree code)

Replaced access to NodeRecord.<variable> with NodeRecord.<getVariable>

1. Changed teh access modifier from public to private for variables
2. Added a new variable for nodedatanumerical
3. added a new constructor

Moved printMessage statements to inside the if loop so that they are not printed each time getInstance is called

Using xml_path_index instead of xml_index to find documents which havnt been indexed.

Replaced hardcoded namespaces with variable defined in metacat.properties

Changed logMetacat to be a local variable in MetaCatServlet to avoid any potential threading issues.

Metacat has had problems with threading issues when accessed from ecogrid. These problems may stem from the use of shared global variables within the servlet that are not protected against threading problems. We used a lot of these, which I am eliminating in this commit. Besides final variables used as constants (which are not a problem), now there are only three unprotected variables (sessionHash, logMetacat, and conn) which are harder to eliminate. I will be discussiong this with Sid tomorrow to see how to eliminate them.

Fixed the bug that replicate data file failed that the documents records wouldn't be deleted.

the parameter of method getRevisionTableReList is docidWithoutRev.

Fixed bug that data file upload failed, record couldn't be deleted.

Bug #2207: Implementation of the Metacat Advanced Search engine.

Fixed a bug in log

Fixed log bug when xml_revision updated failed.

Removed extra package declaration in LSID java file.

Initial checkin of LSID support code for metacat. The LSID support here
provides access to metacat documents through an LSID identifier. The
identifier takes the form:
urn:lsid:ecoinformatics.org:jones:1:1

See http://lsid.sourceforge.net for more details....

2.a If not found go to step 4...

Bugfix for 2091. Removed the function needValidation(). Added function getPrefix which returns the prefix. And use the following steps to find out the namespace

The function returns a string array for a given username. the array contains the name, organization name and email address of the user. In case of ldap, it is cn, o and mail attributes for ldapbase=username...
