Running non-HTTP GenericServlets

[Matt Chamberlain <ma...@thirdspace.tv>]

Hello,

I have recently started using Tomcat, and it's working great for all of my
HttpServlets.  I've also written a non-HTTP servlet (extending
GenericServlet), and I wasn't sure how to set this up in server.xml.
Basically, I just need all requests on port 2147 to come through to my
servlet, without being HTTP parsed (as a web application) etc.  I haven't
been able to find any information on this in the documentation.

Does anyone know how to set up Tomcat to work in this way?

Thanks very much for your help.

Best regards,

Matt

I suspect the key point there is that *Apache* is not able to find the
appropriate page, i.e. it's not even getting to Tomcat.  The web.xml
files are only read by Tomcat.  My guess is you need to insert some
appropriate directives in the tomcat/apache conf file so that Apache
knows to pass these URLs to Tomcat in the first place.  What exactly
those are depends on which module you're using to connect Tomcat to
Apache (mod_jserv, mod_jk, mod_webapp).  Check the tomcat/apache conf
file you have now for samples.

             You can modify the prefix that is matched by adjusting the
             "prefix" parameter below.  Be sure your modified pattern
             starts and ends with a slash.

             NOTE:  This prefix applies to *all* web applications that
             are running in this instance of Tomcat.

        <RequestInterceptor
            className="org.apache.tomcat.request.InvokerInterceptor"
            debug="0" prefix="/servlet/" />

So to add /servlets, you would need something like this in your server.xml :
        <RequestInterceptor
            className="org.apache.tomcat.request.InvokerInterceptor"
            debug="0" prefix="/servlets/" />

Subject: Problem mapping servlets to /servlets/*


Hi,

I am quite new to Tomcat and I have encountered problems in mapping servlets
to specific URLs. Basically, I want my servlets to be activated when invoked
through an URL that contains /servlets/* in addition to default /servlet/*.

I have added the following to my %TOMCAT_HOME%\conf\web.xml:

<web-app>
    [...]
    <servlet-mapping>
        <servlet-name>
            invoker
        </servlet-name>
        <url-pattern>
            /servlets/*
        </url-pattern>
    </servlet-mapping>
    [...]
</web-app>

This does not work. If I point to http://localhost/servlets/IsItWorking
instead of http://localhost/servlet/IsItWorking, Apache is not able to find
the appropriate page.

Any suggestions?

Regards,

Problem mapping servlets to /servlets/*

Hi,

I am quite new to Tomcat and I have encountered problems in mapping servlets
to specific URLs. Basically, I want my servlets to be activated when invoked
through an URL that contains /servlets/* in addition to default /servlet/*.

I have added the following to my %TOMCAT_HOME%\conf\web.xml:

<web-app>
    [...]
    <servlet-mapping>
        <servlet-name>
            invoker
        </servlet-name>
        <url-pattern>
            /servlets/*
        </url-pattern>
    </servlet-mapping>
    [...]
</web-app>

This does not work. If I point to http://localhost/servlets/IsItWorking
instead of http://localhost/servlet/IsItWorking, Apache is not able to find
the appropriate page.

Any suggestions?
