I have a user who is getting the same error. When I try the suggested workaround, I get a 404 error. On my desktop, I can deploy to the same server without error using the REST protocol, which indicates that it's an issue with the user's installation of Jaspersoft Studio. Are there any other settings I can fiddle with to fix this? It seems like a classpath problem from the error message.
