    text
    copied!<p>(Eclipse 3.4, Ganymede)</p> <p>I have an existing Dynamic Web Application project in Eclipse. When I created the project, I specified 'Default configuration for Apache Tomcat v6' under the 'Configuration' drop down.</p> <p>It's a month or 2 down the line, and I would now like to change the configuration to Tomcat 'v5.5'. (This will be the version of Tomcat on the production server.)</p> <p>I have tried the following steps (without success):</p> <ul> <li>I selected <code>Targeted Runtimes</code> under the Project <code>Properties</code><br> The <code>Tomcat v5.5</code> option was disabled and The UI displayed this message:<br> <code>If the runtime you want to select is not displayed or is disabled you may need to uninstall one or more of the currently installed project facets.</code> </li> <li>I then clicked on the <code>Uninstall Facets...</code> link.<br> Under the <code>Runtimes</code> tab, only <code>Tomcat 6</code> displayed.<br> For <code>Dynamic Web Module</code>, I selected version <code>2.4</code> in place of <code>2.5</code>.<br> Under the <code>Runtimes</code> tab, <code>Tomcat 5.5</code> now displayed.<br> However, the UI now displayed this message:<br> <code>Cannot change version of project facet Dynamic Web Module to 2.4.</code><br> The <code>Finish</code> button was disabled - so I reached a dead-end.</li> </ul> <p>I CAN successfully create a NEW Project with a Tomcat v5.5 configuration. For some reason, though, it will not let me downgrade' an existing Project.</p> <p>As a work-around, I created a new Project and copied the source files from the old Project. Nonetheless, the work-around was fairly painful and somewhat clumsy.</p> <p>Can anyone explain how I can 'downgrade' the Project configuration from 'Tomcat 6' to 'Tomcat 5'? Or perhaps shed some light on why this happened?</p> <p>Thanks<br> Pete</p>
