Websphere中的Java WebStart

我们使用WebSphere作为servlet容器，当我将war文件部署到服务器时，键入

http://localhost:9080/jwsProject/launch.jnlp

始终返回下载响应$NotFoundResponse。我们使用JNLPServlet重定向所有请求，异常由jnlp serlvet类引发

以下是war文件布局：

• index.html
• application.jar
• launch.jnlp
• WEB-INF
  • 解放党
  • web.xml

launch.jnlp有：

<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="1.0" codebase="$$codebase" href="launch.jnlp"> 

<information> 
    ...
</information>

<security>
    <all-permissions/>
</security> 

<resources>
    <j2se version="1.2+"/>
    <jar href="application.jar" version="1.0" main="true" download="eager"/>
    <jar href="WEB-INF/lib/jnlp-servlet.jar"/>
    <jar href="WEB-INF/lib/jnlp.jar"/>
</resources>
<application-desc main-class="test.maintest.java">
    <argument...</argument>
</application-desc>
