奇怪的Java Webstart JNLP异常

Question

我有一个使用简单JNLP的java webstart应用程序。最近我在启动它时遇到了奇怪的问题。我以前从来没有遇到过这个问题，我很确定没有任何内容得到修改。当我试图启动这个应用程序时，我得到这个错误。

正如你所看到的，它没有给出哪个标签有问题。就我所知;第33行没有问题。它有一个简单的标签<argument>session_token_here</argument>

更新:这是JNLP文件;

Answer 1

<extension href="https://MASKHOST:5467/jnlp/productplugins.jsp"
 name="Component name/>

应该. .

<extension href="https://MASKHOST:5467/jnlp/productplugins.jsp"
 name="Component name"/>

但是使用JaNeLA检查JNLP并修复发现的任何错误。

Answer 2

这一行:

<java java-vm-args="-Xms64m -Xmx256m -Dsun.java2d.noddraw=true" href="http://java.sun.com/products/autodl/j2se" version="1.6*&1.6.0_05+"/>

有一个嵌入的&，应该像这样转义:

<java java-vm-args="-Xms64m -Xmx256m -Dsun.java2d.noddraw=true" href="http://java.sun.com/products/autodl/j2se" version="1.6*&amp;1.6.0_05+"/>

第一行也有一个未转义的&。

下一行缺少结束双引号:

 <extension href="https://MASKHOST:5467/jnlp/productplugins.jsp" name="Component name/>

但这可能是编校错误

Answer 3

如果没有任何JNLP文件，我可以建议使用Janela JNLP验证器工具

Answer 4

也许你有一个xml注释或挂引号字符"或什么?
