How can I solve it?

Answer 1

The issues might come from the JDK series. I experienced the same issues in most pc with win32 bit and some win64 bit. The issues solved when I tried to downgrade the jdk (JRE) series from 8 to 7. I think you may need these steps;

1. Check your Tomcat version, if you are using Tomcat 7 series you may need jre 7 series and below.

2. Just download the jre kit from here; http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html

3. Change the server preferences to Tomcat 7. ALWAYS CHECK!

4. Restart Eclipse. (I recommend you to use Luna. Its much more stable.)

5. Good luck !

Answer 2

Build the project again, regenerate the war file and add it to the web module.Sometimes the generated war file will be corrupted or will not reflect the new changes.
