    <p>I just tried to use Gears in my GWT application and got following error:</p> <pre><code>Jul 12, 2009 6:26:29 AM com.google.apphosting.utils.jetty.JettyLogger info INFO: jetty-6.1.x Jul 12, 2009 6:26:29 AM com.google.apphosting.utils.jetty.JettyLogger warn WARNING: failed com.google.apphosting.utils.jetty.DevAppEngineWebAppContext@c45809{/,/Users/work/workspace/Athena/war} javax.xml.parsers.FactoryConfigurationError: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found at javax.xml.parsers.SAXParserFactory.newInstance(SAXParserFactory.java:113) at org.mortbay.xml.XmlParser.&lt;init&gt;(XmlParser.java:69) at org.mortbay.jetty.webapp.WebXmlConfiguration.webXmlParser(WebXmlConfiguration.java:83) at org.mortbay.jetty.webapp.WebXmlConfiguration.&lt;init&gt;(WebXmlConfiguration.java:78) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at java.lang.Class.newInstance0(Class.java:350) at java.lang.Class.newInstance(Class.java:303) at org.mortbay.jetty.webapp.WebAppContext.loadConfigurations(WebAppContext.java:838) at org.mortbay.jetty.webapp.WebAppContext.doStart(WebAppContext.java:417) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:40) at org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:117) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:40) at org.mortbay.jetty.handler.HandlerWrapper.doStart(HandlerWrapper.java:117) at org.mortbay.jetty.Server.doStart(Server.java:217) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:40) at com.google.appengine.tools.development.JettyContainerService.startContainer(JettyContainerService.java:147) at com.google.appengine.tools.development.AbstractContainerService.startup(AbstractContainerService.java:116) at com.google.appengine.tools.development.DevAppServerImpl.start(DevAppServerImpl.java:211) at com.google.appengine.tools.development.gwt.AppEngineLauncher.start(AppEngineLauncher.java:86) at com.google.gwt.dev.HostedMode.doStartUpServer(HostedMode.java:365) at com.google.gwt.dev.HostedModeBase.startUp(HostedModeBase.java:590) at com.google.gwt.dev.HostedModeBase.run(HostedModeBase.java:397) at com.google.gwt.dev.HostedMode.main(HostedMode.java:232) </code></pre> <p>I know this error is because I'm using (1) OS X, (2) Eclipse with Google Plugin, (3) <strong>JRE 1.5</strong>. But I have no choice because Hosted Mode plugin requires JRE 1.5 and when I switch to JRE 1.6 Hosted mode complains. I also tried to set JRE 1.6 just to the project, still Plugin does not like it. This problem occurs only when I'm including </p> <pre><code>&lt;inherits name='com.google.gwt.gears.Gears'/&gt; </code></pre> <p>into my gwt.xml file.</p> <p>There is <a href="https://stackoverflow.com/questions/1016286/org-apache-xerces-jaxp-saxparserfactoryimpl-not-found-when-importing-gears-api-in">one guy who has same problem</a>, he solved it by just switching JRE's but I'm using Mac and I assume there is different story with Mac. Is there any solutions to this problem in my case?</p>
