Finding the Jar-file Containing a Known Class

without comments


This post shows how to locate that jar-file that contains the class you need to import into your project. This is helpful for those times when you’re writing a custom solution using the jar-files from a 3rd party.

The quest is to find the jar-file that contains the class, “XmlHelperUtl“.

In the Java bin directory, there is a utility called “forfiles” that can be used to find it. First, launch a DOS window, then change to the dir containing the slew of jar files to search.

Y:\>cd OIPA\PASJava.war\PASJava.war\WEB-INF\lib

Then execute the “forfiles” command.

Y:\OIPA\PASJava.war\PASJava.war\WEB-INF\lib>forfiles /S /M *.jar /C “cmd /c “C:\PROGRA~1\Java\jdk1.7.0_21\bin\jar” -tvf @file | findstr /C:”XmlHelperUtl” && echo @path”

The answer is printed as:
