Tomcat 7 in Eclipse Indigo: Tomcat failing to start

Question

I am trying to run a war file via Tomcat in Eclipse. But, when I am trying to run it, I am getting the following error in Server console:

Aug 2, 2013 4:06:58 AM org.apache.catalina.startup.ClassLoaderFactory validateFile

Please let me know how to solve this.

how do you run the war via Tomcat in Eclipse? – Insecure

I am right-clicking on the war. Then selecting Run As Configuration. In the configuration I am setting Apache Tomcat. – Astrid

I have created a maven project and imported it to Eclipse. In the target folder I have the war file. But when I am trying to Add/Remove resource in Tomcat, it is saying "there are no resources that can be added or removed from the server". – Astrid

Your project should be created as a Dynamic Web Project. Since your project is already created, you should add the Dynamic Web Module facet to it (right-click the project --> Properties --> Project Facets --> check the Dynamic Web Module facet --> OK). – Insecure

I changed it as suggested by you. Now Tomcat is starting fine. But I am getting 404 error when trying to open the resource file. – Astrid

OK let's separate here the questions... Your first question was about ClassNotFoundException when starting Tomcat in Eclipse. I'll move my comment to an official answer. Solving the 404 error justifies a separate question in which you should elaborate on the way you access that resource etc (which might well have nothing to do with Eclipse). – Insecure

Answer 1

Your project should be created as a Dynamic Web Project.

Since your project is already created, you should add the Dynamic Web Module facet to it.

Right-click the project --> Properties --> Project Facets --> check the Dynamic Web Module facet --> OK.
