How to find the missing jar?

If I have a project with hundrends of jar files, and e.g. I have an import of a package that can not be found, how would I find which jar should I include?
I.e. how do I know that package a.b.c is defined in X.jar under /filesystem/jars where under this path there are hundrends of jars?
Is there e.g. a tool to search inside jars? grep-like for jars?

You could also try to add the java option -verbose:class to your startup options, this will produce dumps like:

[Loaded java.security.BasicPermissionCollection from shared objects file]
[Loaded sun.misc.JavaSecurityProtectionDomainAccess from C:\Program Files (x86)\Java\jdk1.6.0_32\jre\lib\rt.jar]
[Loaded java.security.ProtectionDomain$2 from C:\Program Files (x86)\Java\jdk1.6.0_32\jre\lib\rt.jar]
[Loaded java.security.ProtectionDomain$Key from C:\Program Files (x86)\Java\jdk1.6.0_32\jre\lib\rt.jar]
[Loaded java.security.Principal from shared objects file]

I use eclipse with maven. In this environment I can simply open the class and choose View in Package Explorerfrom the context menu. After that the Package Explorer shows the expanded strcuture of the jar in the Maven Dependcies.

Just google with the class name say "org.apache.struts.action.ActionMessages + jar".

You will get the jars which has the respective class.
