Plug class not found during build [message #246561]

I am a developer that is new to the eclipse IDE (version 3.3.1) and have
downloaded some tutorials to learn more about struts and eclipse. I am
receiving the following error:
The project was not built since its build path is incomplete. Cannot find
the class file for javax.servlet.http.HttpServletRequest. Fix the build
path then try building this project
and:
The project was not built since its build path is incomplete. Cannot find
the class file for junit.framework.TestCase. Fix the build path then try
building this project
The plugins are installed (with the WTP 2.0.1) and is displayed in the
list of plugins through the Help>About Elcipse option.
I have tried opening the project using the -clean parameter as well as
cleaning the project before and after the eclipse restart.
Am I missing something in the configuration of the build path? My jre and
jdk are installed, and the jre system library seems to be fine. I have
set the compiler compliance level to 6.0 and the project facets to 6.0. (I
had another problem with that, but figured it out.)
Why is it not finding the classes when I try to build?

Thank you,
Chriss

Hi Chriss,

Using WTP and the provided wizard you can create different projects.

Lets say a - Dynamic Web Project.

On the first page of the wizard you can specify the "Target Runtime" and
if you do not have one there is a button "New" on the same page.

Have you specified the "Target Runtime" for your project? The target
runtime is generally the application server and its libraries (JBoss,
Tomcat, a proprietary server). The runtime will contain the
javax.servlet.http.HttpServletRequest class.

You can also configure the installed "Target Runtimes" from
Window->Preferences->Server->Installed Runtimes.

Is the junit library on your build path? You can check this from project
context menu->Build Path->Configure Build Path->Libraries.

If the junit.jar is not on the build path you can use the Add External
Jar... or Add Variable... buttons to add this jar to your build path.

Best Regards,
Kiril

On a related topic: starting with Eclipse 3.3 the Equinox loader will
restrict loading of Java runtime classes to the java.* packages. Since
you are using javax.* you MUST declare it as a imported package in
your plugin to allow the classloader to load the classes from javax.*
(see http://www.mail-archive.com/equinox-dev@eclipse.org/msg00414 .html
or http://wiki.eclipse.org/index.php/Equinox_Boot_Delegation for
details)
