Struts2应用程序部署时的常见异常

我使用NetBeans IDE 7.0.1和Apache Tomcat 7.0.14.0。我使用IDE构建了一个Struts2应用程序，并且能够很好地构建，无一例外。但是，IDE的服务器日志在所有Struts2应用程序的每个部署时间内都会出现相同的异常。应用程序运行良好，没有其他例外。Struts2应用程序部署时的常见异常

这里是个例外：

我怎样才能避免这种情况？问题在哪里存在？

看起来你在你的库中有一个XML解析器，它与其他人有冲突。尝试使用较新的版本进行更改或删除它。似乎与一些碧玉罐子的问题。 – batbaatar 2012-07-09 04:51:53

@batbaatar，谢谢。我使用struts2，2.2.3版本。它可能有新的或最好的支持XML解析库。我最好使用另一个最新的struts2库2.2.4。但是2.2.3一定要支持好.. – 2012-07-09 06:07:58

java.io.UTFDataFormatException xmlparser

我猜问题是xml文件。

是否从其他文件复制？可能是编码不同，你应该自己输入。尝试添加以下到您的xml文件：

<?xml version="1.0" encoding="UTF-8"?>

顺便说一句，我是一个中国学生，我不擅长英语，对不起。

我试着添加那一行。但它仍然存在。感谢您的关注。中国人对所有语言都很擅长，不要撒谎。 :) – 2012-07-08 16:10:44
