Question

我正在从http://viralpatel.net/blogs/tutorial-create-struts-2-application-eclipse-example/执行来自tuorial的代码，我收到以下错误

我使用的罐子是：

共享记录-1.1.3.jar
公地lang3-3.1.jar
共享记录-1.1.3.jar
freemaker的-2.3.19.jar
了Javassist-3.11.0.GA.jar
ongl-3.0.6.jar
struts2的核 - 2.3.16.jar
XWork的核 - 2.3.16.jar

有人可以告诉我，我错了什么？是Tomcat服务器吗？是代码吗？

另一个问题是我在互联网上尝试更多教程，每次在将struts2应用到网页时都会出错。有人能告诉我Tomcat缺少什么？

P.S。我正在使用Eclipse kepler，这可能是它的问题吗？

Answer 1

缺少Javassist库。您可以从下面的maven下载它是链接。这在异常本身中提到：）

http://mvnrepository.com/artifact/javassist/javassist

执行教程时出现Tomcat错误
