title: Multiple JSTL Versions in Weblogic J2EE App
body: <p>Thanks in advance for taking a look :)</p>
  
  <p>I'm hard at work on a J2EE web app (in JDeveloper) and recently added some functionality that required JSTL, and I've hit a little bit of a snag. Whenever I try to deploy my war on Weblogic 11g, I get the following error on the console:</p>
  
  <blockquote>
    <p>[02:05:43 AM] Must choose only one of
    libraries: JSTL 1.0, JSTL 1.2.</p>
  </blockquote>
  
  <p>I only have one instance of the JSTL library listed under my WebLogic deployments (1.2.0.1).</p>
  
  <p>Here's what I've tried so far:</p>
  
  <ul>
  <li>Google. I've got nothing.</li>
  <li>Removing all files with the string JSTL in them, in both my Weblogic domain folder and my source folder</li>
  <li>Removing all temp files stored by Weblogic</li>
  <li>Rebooting :)</li>
  </ul>
  
  <p>If you have any ideas on ways to squash this, I'd <em>really</em> love to hear them. Thanks!</p>
