In "org.sprintframework.web-3.1.0.M1.jar", I can see "org.springframework.web.context.ContextLoaderListener".

Someone on Google says that spring.jar should be included but I don't see any spring.jar in 3.x distribution.

Eclipse 3.6.2 Tomcat 7

Edit: Someone says "Automatically update dependencies" should be checked in Project Properties but I don't see anything like that in project properties. ClassNotFoundException:org.springframework.web.con text.ContextLoaderListener

Answer 1

Using the "Update project configuartion" messed up the build path of the project.

Fix: Open the "configure build path..." menu (right click on the project) and fix the Included/Excluded options for each source folder. That worked for me.

Answer 2

Same thing happens to me from time to time when using Eclipse WDT. Its specialy frustrating when this happens to a unmodified and previously working project. This is what I do to fix it in this last scenario:

1. Stop Tomcat (if it's running)
2. Open the "Servers" view: Window > Show view > Other > Server > Servers
3. Right Click on Tomcat Server > Clean Tomcat Work Directory.
4. Right Click on Tomcat Server > Clean
5. Restart the server

This usually fixes the issue you mention.

Answer 3

I used IntelliJ IDEA, compilation is successful, but when starting Tomcat, it says:

Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

In the beginning, I thought the JAR was missing, but it was in place.

Solution: File > Project Structure > Artifacts, in the Output Layout double click in right panel Available Elements the library named like Maven:..., it will be moved to WEB-INF/lib in the left pane.

Accept and restart Tomcat.

Answer 4

If everything mentioned above does not work try the following. It worked for me.

Remove your project from the server > Restart server > Add your project to server > Restart server.

Detailed Instruction:

1. Right click on server > Add and Remove
2. Select your project > Remove > Finish
3. Restart your server
4. Right click on server > Add and Remove
5. Select your project > Add > Finish
6. Restart your server again.

Answer 5

Solution for Eclipse Luna:

1. Right Click on maven web project
2. Click 'Properties'menu
3. Select 'Deployment Assembly' in left side of the popped window
4. Click 'Add...' Button in right side of the popped up window
5. Now appear one more popup window(New Assembly Directivies)
6. Click 'Java Build path entries'
7. Click 'Next' Button
8. Click 'Finish' Button, now atomatically close New Assemby Directivies popup window
9. Now click 'Apply' Button and Ok Button
10. Run your webapplication

Answer 6

I tried the

• project clean mvn
• clean
• clean tomcat work directory Automatically
• update dependencies

The only thing that worked at least temporarily was to add Maven Dependencies to Web Deployment Assembly definition

But this does not work for ever! After a couple of days it stops working. My solution was to remove Maven Dependencies, apply change and add Maven Dependencies again.

I'm using - eclipse Juno - embedded maven - tomcat 7
