Find a class somewhere inside dozens of JAR files?
How would you find a particular class name inside lots of jar files? (Looking for the actual class name, not the classes that reference it.) Eclipse can do it, just create a (temporary) project and put your libraries on the projects classpath. Then you can easily find the classes. Another tool, that comes to my mind, is Java Decompiler. It can open a lot of jars at once and helps to find classes as well. Unix Use the jar (or unzip -v ), grep , and find commands. For example, the following will list all the class files that match a given name: for i in *.jar; do jar -tvf "$i" | grep -Hsi
