I'm trying to upload a driver for a plotter in iPrint, but it seems to timeout and gives a error message. I'm able to install other drivers to the broker, and i've got around 20 printers on it.

Heres the error message:
type Exception report


description The server encountered an internal error () that prevented it from fulfilling this request.


com.novell.emframe.fw.servlet.AuthenticatorServlet .service(AuthenticatorServlet.java:341)
javax.servlet.http.HttpServlet.service(HttpServlet .java:802)

note The full stack trace of the root cause is available in the Apache Tomcat/5.0.30 logs.

Any help would be great!
