Resource Query Servlet

Servlet that handles resource registry queries. This servlet takes the following parameters, either from a GET or POST request:

• type which should be either profile or product , indicating what kind of query to perform.
• ns which should be a URL to a CORBA name server, and is optional. If not given, it defaults to the "system" name server defined in the oodtrc.xml file.
• object which is the name of the CORBA object to which to send the query.

Then, either the query parameter must be specified, and its value set to the XML serialized format of an {@link XMLQuery} object, or any of the following may be specified (default values are used for unspecified values):

• keywordQuery is the DIS-style keyword query string.
• id is the ID of the query.
• title is the title of the query.
• desc is the description of the query.
• ddID is the data dictionary ID.
• resultModeID is the return instance, INSTANCE, PROFILE, or CLASS.
• propType is either BROADCAST or PROPOGATE.
• propLevels is how deep to propogate.
• maxResults is how many results to retrieve.
• returnType is the return type of search results.

In response, this servlet delivers the {@link XMLQuery} with results to the requestor in XML format, using the MIME type text/xml .
