CQL/WQL Question

Hi,

I am using OpenPegasus for a project and want to use advanced database requests
Rather than the limited ones using CIM XML. For that I found out that you have WQL/CQL 
support in which _W_QL is confusing me as I cannot find a specification to it.
What is it? WBEM Query Language? I can just find a CQL specification from WBEM.
What is the link between both of them?

I am using the SBLIM Java API to perform CIM-XML requests on the Pegasus server.

Enumeration persons  = cimClient.execQuery(resourceClass, "SELECT OBJECTPATH(Person) AS Path FROM Person WHERE Name LIKE \"Foo%\"", "CQL");

That gives a remote exception on the Pegasus server in which I am told that CQL
Is not a supported query language. However, I compiled Pegasus with:

PEGASUS_DISABLE_PROV_USERCTCT=true
PEGASUS_ENABLE_EXECQUERY=true
PEGASUS_ENABLE_CQL=true
PEGASUS_ENABLE_CMPI_PROVIDER=true

If I use WQL, it works, but it does not appear to support LIKE statements in WHERE
Clauses. If my issue cannot be resolved by using Pegasus' supported query languages I
Would be very pleased about an alternative suggestion to solve it.

Cheers,
Robert
