"Unsupported type" Portlet error

I have a JDBC Data Adaptor that does a simple select all query from a SQL database. This tests and runs fine. It has a _WSD counterpart which Validates with no issues. Both are on IS, and the service runs fine when tested from within IS in Package Management. I can also run the web service from SoapUI and get proper results.

I then created a simple Generic portlet, dropped the _WSD into that, supplied the $dbUser, $dbPassword, and _x0024_connection Name. It is on MWS in the Deploy folders, and comes up fine via SysAdmin, System folder, Portlets, this portlet. When I run it I get back: “Unsupported type http://localhost/Queries/ListTaskTypes __ListTaskTypesOutput” and no results from the query. I do not get an IS error, just this message in the MWS portlet screen. To clarify: ListTaskTypes is the name of the Adaptor service, and I assume _ListTaskTypesOutput is the Response aspect of that service. It returns 2 data columns, both strings: a code, and a description. An example record is: “NetworkUpd” as a code, and “Network: Replacements, Firewall, etc” is the description.

We have webMethods v9.0 SP1 suite.

I would appreciate any help in determining the problem; I haven’t been able to make anything of it.
