Elicpse throw Notfoundexception Exception when new userlibrary import jar Package

Recently began to learn Struts2.0 framework. A sudden whim when importing jar packs. To facilitate the separation of the functionality of the jar package, I would like to create a new Struts folder in the Web-inf. lib directory for easy sorting.

Like this.

Look at the Web library again, then the problem comes. Using tomcat8.0, it should have been generated automatically here.

No, I'll create a new userlibrary called "Struts2". The steps are as follows: Project right-->build path-->configure build path-->libraries tab inside->add library-->user library--> Next-->user libraries...-->new-->add jars.

That's when it happens:

When I restarted the server, there were a lot of notfoundexception exceptions. (In fact, I wrote a few simple filters in front, so the error prompted the Strutsprepareandexecutefilter class can not find.)

At this time I realized maybe the bag didn't lead in, so I daoteng a long, finally here, found the reason. This should be hooked up or not in.

You can modify this: Project Right--->properties-->deploment assembly-->add java build path entries-->next--> STRUTS2 (newly created user Library)-->finish.

OK, it's no problem to run again.

Tips:

In fact, modify the Class-path, the Web-inf Lib directory under the new folder also configured, so that Tomcat automatically help us to generate the jar package, this can also solve the problem.
