ClassNotFoundException when running a Spring + Maven2 project on Tomcat 6 from within Eclipse 3.5

Question

When trying to launch a Web project from within Eclipse I get:

SEVERE: Error configuring application listener of class org.springframework.web.context.Conte         


        

Answer 1

I had the same symptom with a different cause. I had to edit my .classpath file. The maven entry:

<classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER">
    <attributes>
        <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
    </attributes>
</classpathentry>

...was lacking the attributes tag shown here. When I added the attributes tag the problem went away. I'm very curious how to configure that in the eclipse ui.

Answer 2

Note that the steps to install the WTP integration have changed.

See: Maven/Tomcat Projects In Eclipse Indigo/3.7

Answer 3

From time to time, face with same problem.

For some strange reason, this problem could be fixed this way

1) Right mouse click on project Maven -> Disable Maven Dependencies

2) Right mouse click on project Maven -> Enable Maven Dependencies

Answer 4

You seem to have both Eclipse IAM and M2Eclipse stuff in your .classpath. I would do some cleanup:

• Use only one of these plugin (I suggest using M2Eclipse).
• Delete your project from Eclipse's workspace, delete the .classpath and .project and Import the project as a Maven project again.

Update: To get WTP support with M2Eclipse, you need to install the Maven Integration for WTP from the m2eclipse Extras update site: http://download.eclipse.org/m2e-wtp/releases/ as illustrated below:
