Servlet url mapping work incorrect when many servlets have one code

[Druzhiinin Mihail <md...@rcbd.org>]

Dear users,

We have 2 servlets with one code and different init parameters mapped to
different url. On high load requests to first servlet handled by second servlet. I different servlets by init params. It apparent when second servlet was called.
What I do illegal?

web.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

   

    <security-role>
        <role-name>ybs</role-name>
    </security-role>

So, you mean to say that you have a single servlet deployed on two
different URL patterns.

This is highly unlikely. What is the behavior you are actually observing?

What is the symptom?

Your web.xml looks just fine. Could you post some of the code? I suspect
this is a data-sharing issue, and not a Tomcat problem. Do you use any
non-final static members in your servlet class?
