today; this error wasted my time among 10 hours... Its just because of Dynamic web module version 6.0 !!! change that to 5.0

press file > new > Dynamic Web project > in that page change Dynamic web module version to 5.0 > next > finish

then create jar file and be ready to work

As mentioned in this thread, this could be relate to bug 154833:

The current handling of project modules is such that the project name must match the deploy-name in the .settings/org.eclipse.wst.common.component for "everything" to work correctly.
If they don't match, I believe the symptom you are experiencing is one of the "things" that goes wrong.

That's it.
I was able to work around this problem by checking out the shared project into a project with the identical name as the original.
I no longer get the error

I am creating Dynamic web project for first time but same error also there.

My issue was resolved when i followed these steps:

Connect tomcat with eclipse.
Create new Dynamic web project. When creating new project, select "target runtime" as "<none>", and "Configuration" as "Default Configuration".
After creating project, right click on project, select "Run as" > "Run on server" .
You will able to see a pop up window like this: click to see the image

Select the server and click finish.
