Issue: Server Tomcat v7.0 server at localhost failed to start.
It's from the Internet.
Open the following path under your workspace folder:
<workspace-directory>\.metadata\.plugins\org.eclipse.wst.server.core
Delete inside the temp* folder, I have temp0, may be a tomcat corresponding to a temp bar, not very clear, after the deletion of the restart Eclipse,tomcat can be used.
But it didn't work in me, so I followed the code according to the error message.
The error is caused by:java.lang.NoClassDefFoundError:ServletContextEvent
And then suddenly think of it, just pull a recent version of the program, or completely covered the kind of-git reset hard
As a result, the Tomcat server package that was configured in the previous project is erased.
So can not find servletcontextevent corresponding jar bag, so the error can not start;
Workaround:
Re-draw the server configuration again, as shown in the following figure
