UBE Error on Web

I'm trying to run a UBE through Websphere. The UBE works perfectly on a Thick Client, but when run through the web the print fields are blank on the submit page and it returns an error.

I've tried re-creating and redeploying the versions all to no avail.

Has anyone else come across this?

Tim,

Unless I'm mistaken, UBEs run on the Enterprise Server rather than the Web Server for Web clients. Fat clients have the option to run locally or on the Enterprise Server, but web clients only run UBEs on the Enterprise Server. Have you tried re/deploying the UBEs and their versions to your Enterprise Server?
