Question

I have got a JAR file which contains Utility classes, that are used in my Web Application.

Now some of the Utility classes require their respective libraries such as commons-logging, db2java.

But my final Utility JAR being packaged does not contain these required libraries , I tried including them but they are not picked up by the classes.

Can anybody tell me as to how can I include these dependant libraries inside my Utility JAR in such a way that my classes pick them and execute properly.

Answer 1

Just put all the lib’s in your WEB-INF/lib folder and not try to bundle them into one JAR file. Having your libs broken out into their own JAR files is easier to manage.

WEB-INF/lib/
....commons-lang-3.0.jar
....db2java-1.0.jar
....my-utilities-1.0.jar

You can also see the versions of the jars (in case you want to update one) without having to go digging around for them
