hi all, I am quite new with biztalk server. i work with biztalk 2004 and I try to consume web service that has several method that use user defined data types. I added a wse adapter but the schemas representing the user defined types gave the error: \”the schemaLocation ” is an invalid uri\”. when i tried to validate the main schema i got errors: \”schema reference ” is not a valid reference or does not exist in the current project\”. can anyone please help? thanks, hila.
