A user ID and password authorization failure can occur for servlets that use the WebSphere autostart function. This is indicated by a message in the JNI trace.
The following message appears in the JNI trace:
CcicsECI: Authorize userid/password with RACF. Return code = -1, errno = 157
Servlets that use the WebSphere® autostart function do not have the required authority to access CICS® Transaction Gateway.
Use "user-driven" servlets. With these the initialization is performed in the servlet's init() method.
