Ghattu's Technology Blog » JarScan http://ghattus.com A blog about technology that I work on in my day to day job Thu, 03 Dec 2009 00:56:54 +0000 en hourly 1 http://wordpress.org/?v=3.0.1 Find a class in plethora of jars in a directory with JarScan http://ghattus.com/2009/09/17/find-a-class-in-plethora-of-jars-in-a-directory-with-jarscan/ http://ghattus.com/2009/09/17/find-a-class-in-plethora-of-jars-in-a-directory-with-jarscan/#comments Thu, 17 Sep 2009 15:31:48 +0000 sghattu http://ghattus.com/?p=148 Recently I had to find a jar which contains a java class I was looking for. Previously I was using other utilities like Jarfinder, FindClass etc, but wasn’t very happy. 

I found JarScan, which actually works very well and the best part is it is free!. As an example, Under WebLogic 10.0 installation I wanted to find which jar contains the class javax.annotation.PostConstruct. With JarScan you will use,

java -jar /tmp/jarscan.jar -dir /opt/WLPlatform/10.2 -class javax.annotation.PostConstruct

This will return something like,

===============================================
Found: javax.annotation.PostConstruct
Class: javax.annotation.PostConstruct
Package: javax.annotation
Library Name: javax.annotation_1.0.jar
Library Path: /opt/WLPlatform/10.2/modules/javax.annotation_1.0.jar
===============================================
