Error while retrieving windows logged in user ID

[Former Member]

Hi,

We've created an application which reads the windows logged in user ID (not the portal logged in user id). The piece of code retrieves the user id perfectly fine but writes few errors in the trace file. The error is as below:

An exception "com.sap.engine.services.servlets_jsp.server.exceptions.WebIllegalStateException: The stream has already been taken by method [getWriter()]." has occured during application processing. During exception handling, an additional exception "com.sap.engine.services.servlets_jsp.server.exceptions.WebIllegalStateException: The stream has already been taken by method [getWriter()]." was thrown. Both exception has been written to the logfile!

There is no error on the screen but there are errors logged in the trace file. What could be causing the errors.

Ciao,

in your code, did you write something relate to stream(input/output)?

Hi Jun,

I haven't used anything to stream. Could it be because of the deprecated servlet version that i've used up in the DC? i doubt that's the reason, but still asking.
