why doesTomcat not recognize the script? but only treat is as "text"?

Can you view the tomcat start page at:

http://localhost:8080

?

how's your codes look like?

yeah, I think you're going to have to post some example code...

One difference that I can recall between tomcat 4 and tomcat 5 is that its config file is not server.xml anymore. It creates different files for each web app.. Have you checked that part?

THis sounds like a ropey install though...

As if the JSP compiler servlet isn't loading...

to ryancys,
this is not a local server, so I can't test that.

to Kuldeepchaturvedi,
based on the document I have seen, it is still server.xml for configuration. and each application has web.xml as before. but the parameters in server.xml don't look the same between different version.

to TimYates,
I think you are right that the JSP compiler servlet isn't loading. how do we check that, do you know? thanks.

Inside

    /tomcat/conf/web.xml

there should be a section for the JSP compiler servlet like this:

------------

  <!-- The JSP page compiler and execution servlet, which is the mechanism  -->
  <!-- used by Tomcat to support JSP pages.  Traditionally, this servlet    -->
  <!-- is mapped to URL pattern "*.jsp".  This servlet supports the         -->
  <!-- following initialization parameters (default values are in square    -->
  <!-- brackets):                                                           -->

... LOADS of comments snipped out ...

  <!-- If you wish to use Jikes to compile JSP pages:                       -->
  <!--   Set the init parameter "compiler" to "jikes".  Define              -->
  <!--   the property "-Dbuild.compiler.emacs=true" when starting Tomcat    -->
  <!--   by adding the above to your CATALINA_OPTS environment variable.    -->
  <!--   If you get an error reporting that jikes can't use UTF8 encoding,  -->
  <!--   try setting the init parameter "javaEncoding" to "ISO-8859-1".     -->

    <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>

 ... then on the last page of the file ...

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

I reckon either

a)  Someone's commented that bit out (or removed the file)

or

b)  Someone has stripped out the web.xml file thinking they were in WEB-INF inside a web application...

if its loading the jsp as a text file, this means.. server is up and running and recieving the request.
but intercepter is not working... so I go with Tim on it.. somebody messed up the web.xml...
try copying one from an up & running tomcat and see if that works...

thanks.
but, I created a WEB-INF under my application directory and put web.xml in it. I thought Tomcat will find the application web.xml before it loads the tomcat/conf/web.xml for all the server. is that right?

thanks to all. I finally get Tomcat to compile the codes. But, after I modified the /tomcat/conf/web.xml to add my servlet entry, and put this modified web.xml to myApplication/WEB-INF/ to be my application web.xml, I restart the server and got the following message:
