Thanks all,
I managed to alleviate the problem by installing the new version (2.3?)
of JRun.
The problem was not due to any dbms access as a System.out in the first
line of the servlets init() method was not printed until 5-10 seconds
after the Post was submitted.
Servlet loading and execution was the almost immediate.
As noted, JRun 2.3 has solved the problem.
On further examination I expect the problem was due to the
overinstallation of Microsoft products (inc. beta software) on our test
server. My project manager is a MS zealot and brought the test server to
a virtual halt after installing as many MS Visual Studio/MSDN tools as
he could find.
Thankfully thats nearly all gone too.
Cheers,
Andy
