If you have maxThreads=100 and you create a filter which blocks A if
threadRunningA=10 and blocks B if threadsRunningB=90 than you can tune it the
way you want it to be without seeing TooManyThreads errors from Tomcat. Or make
it 9 vs. 89 to be safe.
Still it doesn't solve you real problem about not being able to deliver enough
performance to handle the total load. Which is probably solvable by profiling
your application or running a cluster or splitting the services over more
machines.

Thanks for your response Ronald!
Won't a filter be a part of the thread pool? I mean every incoming request would create a new thread and filter would be invoked on this new thread ...right?
The solution that I am looking for is to partition the thread pool into 2 parts
One that serves the webpage requests and the other that is allocated to the internal processing of the web application.
Thanks!

You can create a filter or run on separate Tomcat instances.
NB: You are not solving the cause, but the effect. You don't have enough
threads or cpu-power to handle the total load.

Hi,
I have the following attributes in the "server.xml" file:
<Connector port="80"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true" />
The web application that I am working on exposes many webservices, which are invoked from
other applications. The problem I am facing is that when my application gets a lot of
webservice requests, it reaches the limit of "maxThreads". After this limit is
reached I am not able to open the webpage for my web application.
Is there any way to configure my web application such that I have a separate
quota of threads for webpage access and a separate quota for other types of
accesses like webservice requests?
Thanks!
Prashant
