    <p><strong>Context</strong><br/></p> <p>I'm working on a project where we use <a href="http://jung.sourceforge.net" rel="nofollow">JUNG libraries</a>. My custom java code and the Jung libraries are all placed under the wwwroot/WEB-INF/lib. </p> <p>Note that, Certain classes of JUNG depend on Apache commons-collections.jar which is also present in the same folder (given by default by CF).</p> <p><strong>Problem</strong><br/></p> <p>We are in plan to move from CF7 to CF10, so, I'm doing a pilot testing on all the code in the project and found that certain code (that uses the JUNG) are failing with a 'class not found' exception.</p> <p>On debug and checking the methods in the <em>commons-collections-2.1.jar</em> given in CF 10, I found that its different from the one present in CF 7. If I update the JAR to the latest commons-collections-3.2.1 version, the code works fine as it found all those classes needed.</p> <p>I can change my code base to suit the default <em>commons-collections-2.1.jar</em>, but that would result in atleast 2-3 months of dev-test cycle. I want to take it as last option and better avoid it if at all possible.</p> <p>Now, my questions are - </p> <ol> <li>What would be the problem if I change(update) the 2.1 with 3.2.1?</li> <li>What could be the parts of core CF that uses this JAR ?</li> <li>Why does CF uses this outdated 2.1 (i feel so) JAR version ?</li> </ol> <p><strong>Home work I did</strong><br/></p> <ul> <li><p><strong>Testing</strong> : For not effecting the rest of applications, I have created a separate instance, changed the JAR to the latest 3.2.1, hosted my application on it and done some testing. Everything seems fine as I have not encountered any problems. But, I worry that there may be areas in CF that depends on this JAR and might break.</p></li> <li><p><strong>cfusion\lib</strong> : I have found that the commons-collections-3.2.1 already exists in the main lib (cfusion\lib) folder. So, may be, changing the JAR in the WEB-INF/lib does not make any difference.</p></li> <li><p><strong>cfusion\wwwroot\WEB-INF\lib</strong> : I have read that any JAR files placed in this folder are used for the applications only and not by the CF itself. I may be wrong or completely misunderstood the meaning. Correct Me!</p></li> </ul> <p>Answers to this Q would help to my understanding of CF more as well as solve the problem.</p>

    1. COThis seems odd. I am still running ColdFusion 9 and checked my settings for the commons-collections jar. It is using `commons-collections-3.2.1.jar` from the `/cfusion/lib/` folder. I cannot imagine that Adobe reverted back for ColdFusion 10. You say that you found the `commons-collections-3.2.1.jar` file in your `/cfusion/lib/` folder as well. If your server is not using that one then where is it pulling the `commons-collections-2.1.jar` file from? _Could someone verify which jar file is being used on your ColdFusion 10 installation?_

    2. COcommons-collections-3.2.1.jar is being used in my CF10 (update 7) install as well (Mac OS 10.8.2).

    3. CO*commons-collections-2.1.jar given in CF 10, I found that its different from the one present in CF 7* Different how? Because they both claim to be version 2.1. *class not found' exception* Can you edit your post to include the full stack trace? *What could be the parts of core CF that uses this JAR ?* Unfortunately it is hard to say. From the [project description](http://commons.apache.org/proper/commons-collections/) it is very general library involving Collections (think structures). So it and could be used anywhere. The main difference is 2.x supports older jvm's and 3.x requires jvm 1.5+
