Hi,
More questions, more details please:
The error occurs within jmeter or at the servlet side?
Try to use other jdk than ibm's for jmeter.
Are you running jmeter on a different machine?
(otherwise the jmeter itself will alter the result of the benchmark).
What are the results jswdk vs. jserv+apache on the same JVM (blackdown) ?
Thanks,
Cezar.
