Java Servlet Deployment Descriptor Question

[Nazario Cipriani]

Hi guys,

my question is as follows.
If I assume the desployment descriptor below (shortened):

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name> XYZ </display-name>
<description> XZY </description>

<servlet>
<servlet-name> servlet </servlet-name>
<servlet-class>
soap.SoapServlet
</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>servlet</servlet-name>
<url-pattern>/servlet_1/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>servlet</servlet-name>
<url-pattern>/servlet_2/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>servlet</servlet-name>
<url-pattern>/servlet_3/*</url-pattern>
</servlet-mapping>
</web-app>

Now my question: Is the same servlet instance accessed by three
different URLs or is there for each URL an own servlet instance running
(are there three instances of the servlet running)?

Regards,
Nazario.

Hi,

AFAIK, there will be only 1 instance of the servlet running in this
case.

However, it'd be interesting to know if you put 3 servlet elements all
pointing to the same <servlet-class> but with different <servlet-name>.
In that case, I believe it'd be 3 instances.
