Metacat

Add a new overload method - createResultDocument and add a new check for null.

got paging working. metacat also now caches resultsets for users' sessions. the paging is a bit slow, due to some xpath statements. i need to get this optimized now.

Fix bug in advanced search that first surfaced in Java 1.5.0/Tomcat 5.5. Only set the sessid parameter if the sessionId string that is passed in is non-null.

adding changes to make paged query results possible

Change the exception handle way accroding the change in SpatialDataset class.

Change the shape file store object to be static and make them synchronized in order to be thread safe.
