TOMCAT - HTTP Status 404 [duplicate]

Solution 1:

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

Solution 2:

To get your program to run, please put jsp files under web-content and not under WEB-INF because in Eclipse the files are not accessed there by the server, so try starting the server and browsing to URL:

http://localhost:8080/YourProject/yourfile.jsp

then your problem will be solved.

Solution 3:

You don't have to use Tomcat installation as a server location. It is much easier just to copy the files in the ROOT folder.

Eclipse forgets to copy the default apps (ROOT, examples, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.8\webapps, R-click on the ROOT folder and copy it. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like your-eclipse-workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or ../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder, R-click, and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.
