JNLParseException[ 无法解析启动文件。第 6 行出错。]

Question

我正在使用 JNLP 在浏览器上加载一个 Applet。我的小程序运行在 java 版本 Java 1.7.0_25 下没问题，但在运行 Java 1.7.0_45 时遇到问题。我的错误堆栈跟踪如下

NLParseException[ Could not parse launch file. Error at line 6.]

我的 jnlp 文件是

<%@taglib uri="/struts-tags" prefix="s"%>

</jnlp>

我没有遇到问题 - 我的 jnlp 文件有问题或 java 版本有问题？

Answer 1

问题出在我的服务器端代码中，而不是在 JNLP 文件中。
