Answer 1

Well a little bit of googling says that the this class is in:

http://repo1.maven.org/maven2/org/apache/tiles/tiles-servlet/2.2.2/tiles-servlet-2.2.2.jar

this jar. If it still not works try googling somethink like: org/apache/tiles/web/startup/TilesListener jar

Answer 2

Use findjar.com for such situations where you don't know which jar to add to classpath.

In your case the system is not able to load the definition of TilesListener. So, probably you want to add that class to your classpath. For that the related jar can be found at, http://www.findjar.com/index.x?query=org%2Fapache%2Ftiles%2Fweb%2Fstartup%2FTilesListener Just click on the [class] link.

Answer 3

Add This jar file to library packages if you are using any ide or else set classpath of the class
