Creating A New Context

[aas1611]

Hi!

I just start learning Jakarta Tomcat. My first assignment is to create a new context (called learning) under webapps directory. After following the instruction carefully, and copying a java class called IsItWorking into /learning/servlet, I ended up with a message that says this class can not be found, even though I put it in a correct directory.

On my browser, I typed:

http://localhost:8080/learning/servlet/IsItWorking

I've made several trials, like putting this class one directory higher (/learning) and tried to open it with:

http://localhost:8080/learning/IsItWorking

and still, it didn't work.

Is there some procedure I might overlook? What can cause this error message?

Please help! And thanks in advance...

Andre

1) Classes deployed under tomcat should be in packages.
2) They should either be archived into a jar file, and put into WEB-INF/lib, or put unjarred into WEB-INF/classes.
3) You must alter web.xml to map your servlet to a URL.

So if your class was in a package called acme.com, your would deploy it into TOMCAT_HOME/webapps/learning/WEB-INF/classes/acme/com

Then in web.xml, you should add the following :

        <servlet>
                <servlet-name>IsItWorking</servlet-name>
                <servlet-class>acme.com.IsItWorking</servlet-class>
                <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
                <servlet-name>IsItWorking</servlet-name>
                <url-pattern>/servlet/IsItWorking</url-pattern>
        </servlet-mapping>

I was not supposed to use the package for the first assignment or alter the web.xml (because it will be explained later). I was supposed to create the directory manually.

Anyway, I managed to make it work. It was the way I added the context under ContextAdmin. What I don't understand is, I put the IsItWorking.class under learning/WEB-INF/classes, then call it from my browser with this:

http://localhost:8080/learning/servlet/IsItWorking

It works, even though my servlet folder is empty.

Does it have something to do with a configuration? If yes, which configuration is it (where I can see it)? If no, what then?

confused...
