Querying TREX for catalog information

Question

I'm having some trouble understanding how I can send queries to our TREX server to get catalog information.
I'm trying to do this in 2 cases, one of which I have working correctly.
CASE 1:  Pull product information out of TREX based on material number.  I have successfully done this with the following code.
String strObjectID = request.getParameter("id"); 
WebCatItemList itemList = null;
CatalogFilterFactory cff = CatalogFilterFactory.getInstance();       
IQueryStatement queryStmt;
try {
     queryStmt = theCatalog.getCatalog().createQueryStatement();
     IFilter filter = cff.createAttrEqualValue("OBJECT_ID", strObjectID);
     queryStmt.setStatement(filter, null, null);
     IQuery query = theCatalog.getCatalog().createQuery(queryStmt);               
     log.info("CatalogQueryAction: Query Stmt=" + queryStmt.toString());     
     itemList = new WebCatItemList(theCatalog, query);               
} catch (CatalogException e) {
     // TODO Auto-generated catch block
     log.info("backend.exception: " + e);
     e.printStackTrace();
WebCatItem item = itemList.getItem(0);
CASE 2:  Pull category information based on category name.  here is my code thus far.  Every time I load my test page I get a return of nothing.
IQueryStatement queryStatement;
CatalogFilterFactory cff = CatalogFilterFactory.getInstance();
String tarReturn = "nothing";
try {
     queryStatement = theCatalog.getCatalog().createQueryStatement();
     //area or description
     //parent_area
     //IFilter desc = cff.createAttrEqualValue("AREA", "Selector Switches");
     IFilter desc = cff.createAttrEqualValue("CATEGORY_ID", "DDB7ECAF654748F1B75B001EC9F38646");
     queryStatement.setStatement(desc, null, null);
     IQuery query = theCatalog.getCatalog().createQuery(queryStatement);
     Iterator results = query.submit();
     while(results.hasNext()){
          tarReturn = "got here";
     request.setAttribute("result", tarReturn);
} catch (CatalogException e) {
     e.printStackTrace();               
     request.setAttribute("result", e.toString());
I tried using the same method in case 1, but I can't seem to figure out how to get it working.  I know that the cfg/catalog-site-config.xml file plays a part in the TREX queries, but I'm not exactly sure what part it plays.
Many thanks!

Formatting got screwed up.

Hi Brian,
I have checked file "cfg/catalog-site-config.xml" on my local.
Please check file "cfg/catalog-site-config.xml". you can find entry for "OBJECT_ID" under <Map ID="siteMapID"> and "<QuickSearchAttributes> but you cannot find any entry for "CATEGORY_ID" in file.
I think this the reason that you are getting a result for "OBJECT_ID" and not getting result when you use "CATEGORY_ID" because there is no entry for "CATEGORY_ID".
I assume if you make entry of "CATEGORY_ID" then you will able to get result.
By the way which xml file you use? under isaweb~webcatadmin or tcweb~core
I hope this information will help you to resolve your problem.
