Java_exception starting filter struts2 what to do

1 Make sure that you have these two files in your project and that none is imported

2 if not, and you set up the Struts development mode , and your Tomcat path has spaces, most of the time is the reason for program file, you need to reinstall Tomcat. As long as the Tomcat installation path does not have spaces, then redeployment will resolve.

Note that the so-called re-installation, Just copy to a new directory (we know that the manual start Tomcat is this startup.bat file, generally nothing will not be manually to start it, do not manually to start it, otherwise myeclipse call when the error, said the port is occupied), below I put Tomcat on the D disk

Re-deploy MyEclipse.
