ClassNotFOundException? – Command to find the required jar

Posted by Vivek on February 2, 2015

It is irritating when one gets ClassNotFoundException. One can go and find the jar and add it to the classpath to resolve the problem. Jars can be searched on sites like http://www.findjar.com. However, sometimes jars are within the system and only thing needed to fix the problem is to set the classpath appropriately. Here is the unix command to find the jar:
$ find . -name “*.jar” -print -exec jar -tf ‘{}’ \; | grep -E “jar$|String\.class”
