[SOLVED] Problem using jsp:forward to a servlet

[Norm]

I've just started working with Tomcat (version 5.5) and am having the following problem;

I have a jsp page (..\webapps\Norms\jsp\process.jsp) with the following forward statement.
<jsp:forward page="/servlet/DBHandler"/>

The app is started with the URL: http://127.0.0.1:8080/Norms/forms/register.html

The register.html file (...\webapps\Norms\forms\register.html) has the following <form:
<form action="/Norms/jsp/forms/process.jsp" method=post>

I have a servlet program: DBHandler.java (not in a package) that I've compiled and put copies of the class file in many locations in a folder called servlet.

I get a 404 error message when I load the html file, submit the form to the jsp page and it tries to forward to the servlet.

Estado HTTP 404 - /Norms/servlet/DBHandler (in Spanish)

Do I need entries in any xml files or in a tld file or where do I put the class file so that the jsp engine will find it.

Thanks,
Norm

I got it to work by puttiing the program DBHandler in package: forms and added the following to the web.xml file in Norms/WEB-INF/

    <servlet>
      <servlet-name>          DBHandler      </servlet-name>
      <servlet-class>         forms.DBHandler      </servlet-class>
    </servlet>


    <servlet-mapping>
        <servlet-name>        DBHandler          </servlet-name>
        <url-pattern>        /servlet/DBHandler  </url-pattern>
    </servlet-mapping>

The path to the class file is:
"C:\Archivos de programa\Apache Software Foundation\Tomcat 5.5\webapps\Norms\WEB-INF\classes\forms\DBHandler.class"

Hi Norm,

I have been struggling with the error message, below, with the
<jsp:forward page="/servlet/DBHandler"/> in process.jsp.

java.lang.NoClassDefFoundError: forms/DBHandler (wrong name: DBHandler)

I will appreciate that you post the whole structure of the register jsp application for me to follow.

Or zip the folder Norm for me to download?

Thanks a lot.

Hello,

Never mind, I got it now.

<jsp:forward page="/servlet/DBHandler"/> in process.jsp.
is looking for the url mapping for /servlet/DBHandler
I had it set as seen below in web.xml.

<servlet>
<servlet-name> DBHandler </servlet-name>
<servlet-class> DBHandler </servlet-class>
</servlet>


<servlet-mapping>
<servlet-name> DBHandler </servlet-name>
<url-pattern> /servlet/DBHandler </url-pattern>
</servlet-mapping>

So it is looking for the DBHandler servlet-name that is the DBHandler class.
