    text
    copied!<p>I have an Eclipse with Google App Engine Plugin and Google App Engine SDK 1.3.0 installed on. I have created a new web project with Google App Engine SDK 1.3.0. Now, I want to add a library for some advanced JSTL syntax in jsp file, it's is EL-functors (<a href="http://el-functors.sourceforge.net" rel="nofollow noreferrer">http://el-functors.sourceforge.net</a>). In order for EL-functors to pickup its advanced syntax in jsp file and compile them to standard jsp syntax, I must add some listener to the web.xml:</p> <pre><code>&lt;listener&gt; &lt;listener-class&gt;beanface.el.functor.InstallFunctorListener&lt;/listener-class&gt; &lt;/listener&gt; </code></pre> <p>Also, I have added standar.jar, jstl.jar, el-functors-1.0.3.jar to my build path. However, when I kick off web server (using Debug As>Web Project), in the console log, I see this error message:</p> <pre><code>Initializing AppEngine server Feb 5, 2010 7:22:45 AM com.google.apphosting.utils.jetty.JettyLogger warn WARNING: Could not instantiate listener beanface.el.functor.InstallFunctorListener java.lang.ClassNotFoundException: beanface.el.functor.InstallFunctorListener at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at ........ at com.google.gwt.dev.DevMode.doStartUpServer(DevMode.java:421) at com.google.gwt.dev.DevModeBase.startUp(DevModeBase.java:1035) at com.google.gwt.dev.DevModeBase.run(DevModeBase.java:783) at com.google.gwt.dev.DevMode.main(DevMode.java:275) </code></pre> <p>I guess there should be some causes lead to the library is not loaded. When I come to war/WEB-INF/lib, I cannot see standard.jar, jstl.jar and el-functors.1.0.3.jar overthere; only google app engine jars being deployed.</p> <p>What is the problem there, how can I fix that?</p>
