I am learning to use Eclipse 3.1.2 SDK.
I have used a tutorial to make a sample web application for customer orders.

Now I have made the respective classes.

But in that tutorial it is not given how to test the application from the eclipse.

My Webserver is Apache Tomcat 4.0.1 & i am using j2se 1.4.0 .

Also when i am editing the web.xml file build by the eclipse it is giving me the following message on the console tab:

Buildfile: C:\Eclipse\Jiggi\.metadata\.plugins\org.eclipse.js t.j2ee.ejb.annotations.xdoclet\tempAnt.xml

C:\Eclipse\Jiggi\.metadata\.plugins\org.eclipse.js t.j2ee.ejb.annotations.xdoclet\tempAnt.xml:56: taskdef class xdoclet.modules.web.WebDocletTask cannot be found

Total time: 2 seconds

What's this & when i am editing this file & adding some new elements to this web.xml it takes a lot of time??

What is happening??

So please solve my doubts mentioned above & let me know how to test my web application from the Eclipse??
