web start 问题

[cc8294895]

我用java swing写了一个应用程序。现在用web start让他在网页上显示，就第一个窗口出来就出错了。
以下是错误的信息

*.jnlp文件是：
<?xml version="1.0" encoding="UTF-8"?>
<jnlp codebase="http://127.0.0.1:6060/webstart">
<information>

<description>HelloWorld Test Example for WebStart.</description>

<j2se version="1.5+"/>
<jar href="./ui/ui.jar"/>
</resources>

</jnlp>


如果 单独运行ui.jar是正确的。

.\icon\save.jpg 这个是你本地的还是打在jar里的？

[cc8294895]

这个是在本地的 没有 打入包里。但是我运行包的时候他可以找到。难道是这个的问题

我在这个项目放包的地方直接运行这个包可以找到这个文件

我现在 用web start来做。我把程序打包好，也签名了。用java -jar 运行正常。
但在webstart运行出错。帮我看下。
