Metacat

changed the detailCode for DataOne exceptions to a string

implemented update in ResourceHandler and fixed a bug in CrudService where data files were not handled correctly on update

removed system.outs

amost have update working. still need to get unit test squared away.

added exception testing to the crud test

getting getSystemMetadata to work

removed system.outs

removed CrudService dependency on servlet params. CrudService is now a singleton. I'm getting an error from metacat saying it can't find teh systemmetadata schema, even though it is, in fact, registered with metacat. need to identify why this is happening.

adding a system to track system metadata documents for dataone

Added initial implementation of getSystemMetadata and its associated REST service. Current implementation is returning a hardcoded system metadata document -- need to look up the real document for each guid and return that.
