How to find the missing jar?

Question

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?

Have a look at this answer [find a jar file given the class name][1] [1]: http://stackoverflow.com/questions/1500141/find-a-jar-file-given-the-class-name — akluth, Sep 13 '12 at 08:25

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

You will get the jars which has the respective class.

you can also search in http://www.jarfinder.com.

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]
