title: org.apache.xerces.jaxp.SAXParserFactoryImpl not found when importing Gears API in GWT
body: <p>I've created a <a href="http://code.google.com/appengine/docs/" rel="nofollow noreferrer">GWT</a> project using Eclipse which was working perfectly (I was able to run it in both Hosted Mode and on Google App Engine) until I tried to import the <a href="http://code.google.com/docreader/#p=gwt-google-apis&amp;s=gwt-google-apis&amp;t=GearsGettingStarted" rel="nofollow noreferrer">Gears API for Google Web Toolkit</a>.  After adding the following line to my java source file:</p>
  
  <pre><code>import com.google.gwt.gears.client.geolocation.Geolocation;
  </code></pre>
  
  <p>I get the following error when I try to compile:</p>
  
  <pre><code>19-Jun-2009 3:36:09 AM com.google.apphosting.utils.jetty.JettyLogger warn
  WARNING: failed com.google.apphosting.utils.jetty.DevAppEngineWebAppContext@1c7d682{/,C:\Documents and Settings\Geoff Denning\workspace\TaskPath\war}
  javax.xml.parsers.FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found
  </code></pre>
  
  <p>I've already added the gwt-gears.jar file to my \war\WEB-INF\lib directory, and I've referenced it in Eclipse as follows:</p>

  </p>
  
  <p>I've even opened the gwt-gears.jar file and confirmed that org/apache/xerces/jaxp/SAXParserFactoryImpl.class does exist.  Can anyone give me any pointers as to why I'm getting the above error?</p>
