Java Web启动（FailedDownloadException）

当我尝试启动java web start应用程序时，出现以下错误：

com.sun.deploy.net.FailedDownloadException: Unable to load resource: http://localhost:8080/blog/WebStartApp.jar
    at com.sun.deploy.net.DownloadEngine.actionDownload(Unknown Source)

样品。jnlp

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+"
      codebase="http://localhost:8080/blog/" 
      href="sample.jnlp">
   <information>
      <title>Sample JWS application</title>
      <vendor>JBoss tutorials</vendor>
      <description>JWS on JBoss Demo</description>
   </information>
   <secruity>
    <all-permissions/>
   </secruity>
   <resources>     
       <jar href="WebStartApp.jar"/>   
    <j2se version="1.6.10+"
          href="http://java.sun.com/products/autodl/j2se" java-vm-args="-Djava.net.preferIPv4Stack=true"/>
   </resources>
   <application-desc main-class="webStartClasses.App"/>
</jnlp>

Jnlp和jar文件放在。部署在JBoss服务器上的war文件
