Re: Which Engine is Which

[Adrian Lanning]

Hi,
Let's define some terminology so we don't confuse ourselves.
Engine - when talking about Tomcat "engine" means <engine> as per tomcat's
configuration file.
Servlet - programs that process / handle requests.

The program (servlet) that processes jsps is a servlet just like any custom
servlet you write.

The only difference is that the servlet that handles jsps is defined for you
TOMCAT_HOME/conf/web.xml as:

    <servlet>
        <servlet-name>jsp</servlet-name>
        <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
        <init-param>
            <param-name>fork</param-name>
            <param-value>false</param-value>
        </init-param>
        <init-param>
            <param-name>xpoweredBy</param-name>
            <param-value>false</param-value>
        </init-param>
        <load-on-startup>3</load-on-startup>
    </servlet>

    <!-- The mapping for the JSP servlet -->
    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.jsp</url-pattern>
    </servlet-mapping>

    <servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>*.jspx</url-pattern>
    </servlet-mapping>



For your own servlets you define your own web.xml file with your own
mappings and place it in the WEB-INF directory of your app.

Hope that clears it up.
Adrian

Hi there



This is probably something I should know but, for clarification, is the
"engine" that processes jsp's different to the one that processes servlets?
Also what is the name of the engine that processes JSP's and, if different,
the name of the "engine" that processes servlets.



Thanks!



Kind Regards
