Failed to publish to server. Tomcat 7.0

Question

When I try to deploy a war file on a Tomcat 7.0.28 server, I get lower. My Eclipse is the Eclipse Java EE IDE for web developers. Versions: Indigo Service Release 2 Build id: 20120216-1857. I would appreciate if anyone can provide a solution / fix? Is this related to the eclipse or tomcat compatibility version? Thanks.

Answer 1

If you are using the Eclipse or Myeclipse IDE, clean all projects, such as Project -> Clean -> Clean all projects -> Ok. Now its working fine

Answer 2

Following this topic, I will refer to the solution http://www.eclipse.org/forums/index.php/m/526327/

It seems that the deployment configuration file for your application has become wrong.

What happened to me is that if I changed the parameters of my server and unchecked "Submit modules without publishing", the server will start. With it, I received the error you indicated.

For me, the problem is that eclipse could not find my web.xml. My solution was that I needed to go to my project settings and delete the link to my webapp folder in the "Install Deployment" section. This led to a dialog about the location of my deployment description. After Eclipse it was that the reboot got everything in order.

Answer 3

This seems to be a mistake. Here is a workaround;

When adding a new server, do not add the web application to the server. Just add a server without a web module. After adding the server, right-click on the server and add and remove. Now this should work.

Answer 4

had the same problem with Eclipse Neon 2 (4.6.2) and Tomcat 8.5. The workaround is working. Add a server, but do not add an application to it. Then run the "Run on server" application and it will start working. You also need to say that I deleted the entire Maven repository and restarted Eclipse. After restarting, Maven downloaded all the dependencies. I did not like deleting the repository, but it seems like this is also an important part for troubleshooting.

Answer 5

I ran into the same problem. Just remove the server alone. Add a new server and projects to the server. Clean the Tomcat working directory. Then start the server, it will work fine
