Failed to load applet in HTML page

Question

Hi,
I cannot load my applet under IE9+, Chrome (v28). The applet is signed because it access to file resources.
Applet deployment, Javascript code:
<script type="text/javascript" src="http://www.java.com/js/deployJava.js"></script>
<script>
if (deployJava.isPlugin2()) {
  // Launch as JNLP style applet if plugin2 is available
  var attributes = {'/files/ldep.jnlp'} ;
} else {
  // old plugin and MacOS case  (currently isPlugin2() always false for MacOS)
  var attributes = { id:'ifsAuth', code:'org.ldep.AdminLogin', archive:'ldep.jar', width:1, height:1} ;
// minimum Java needed:  1.5 or above
var minimumVersion = '1.5.0' ;
deployJava.runApplet(attributes, parameters, minimumVersion);
</script>
JNLP:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp codebase="" href="">
  <information>
  <title>LDEP Applet</title>
  <vendor>LDEP</vendor>
  </information>
    <security>
        <all-permissions/>
    </security>
  <resources os="Windows">
  <j2se version="1.5+" href="http://java.sun.com/products/autodl/j2se" />
  <jar href="/files/ldep.jar" main="true" />
  <nativelib href="/files/ldep-win32.jar" />
  </resources>
  <applet-desc name="ldep" main-class="org.ldep.AdminLogin" width="1" height="1" />
</jnlp>
Is there something wrong in this code?
Thanks.

Applets run client side - which means the relevant class files need to be downloaded to the client.
Anything under the WEB-INF directory is not directly accessible by the client. Nothing under WEB-INF can be downloaded.
ergo, specifying the WEB-INF directory as part of your applet codebase is a bad idea.
I would suggest try copying the applet classes from under WEB-INF to some other place in your application.
Also, you should probably specify the full class name of your Applet in the plugin tag.
<%@ page import="com.util.MyApplet" %>
<jsp:plugin type="applet" code="com.util.MyApplet" codebase="/classes" width="250" height="100" jreversion="1.6">
     <jsp:fallback>
          <B>Unable to start plugin!</B>
     </jsp:fallback>
</jsp:plugin>cheers,
