Logs and Error Conditions
Logs and Error Conditions
Errors can be logged in OSS and Server log files.
Servlet Logging
SSC processes report configuration and status information to the standard output
(stdout) file, and report errors and exceptions to the ems log and server log files.
Configuration and Status Information
NSJSP processes report the following kinds of information to the standard output file:
•
A message indicating that the NSJSP process has started up, or failed to start.
•
Any message written to the standard output file by a servlet or servlet method. For
example, the default init() method writes a message reporting that it was
invoked.
Exception Message Format
When an error occurs during startup, the container reports an EMS message
consisting of the following elements:
•
A line that reports the date, the time, the process name, and the syslog severity
category, as described in the OSS manual set.
•
The prefix (SSC). SSC is the "older" name for the NSJSP process, still used in
error messages.
•
A field identifying the SSC—matching the SSC name (ssc-name) part of the
URL— if the servlet was loaded in response to a URL reference. This field is not
present if the error occurred while the SSC process was starting up.
•
A descriptive string, for example, " (#7001) Servlet Server Class started. Version
Procedure = T1222V10_XXXX_XX". This message indicates that the servlet server
class (the NSJSP process) has been started.
The new ems messages for the T1222 (NSJSP process) are as follows. They are also
documented in the iTP Secure WebServer Operator Messages Manual.
Event #7001 Servlet Server Class started. Version Procedure =
%VPROC%
where %VPROC% is the version procedure number. The NSJSP process has
started.
Event #7002 Servlet Server Class object code vproc %VPROC1% does
not match Class file vproc: %VPROC2% Terminating Server.
where %VPROC1% and %VPROC2% are the vprocs of the two T1222 product
components. You must re-install the NSJSP process.
