The PerformRQLQuery Web service executes a given RQL string on the repository specified by the pRepositoryPath argument, and returns items of the type specified by the pItemDescriptorName argument. The given RQL string cannot contain parameters, since RQL expects parameters in the form of an array of Objects. The Web service calls through to the performRQLQuery method of the atg.repository.RepositoryServices class, which handles all logic, error checking, and result transformation.
