Answer 1

The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: C:\Program Files\Java\jdk1.5.0\bin;E:\Program Files\Apache Software Foundation\Tomcat 6.0\bin环境变量错误，找不到jdk

Answer 2

很早以前就建议过了不要使用 MyEclipse 内置的 tomcat，这个高度集成的 IDE 只会让人越用越傻。

Answer 3

集成的东西也不好用啊，你JDK没设置把

Answer 4

先把struts的例子装上试一下。好像会有检测。

Answer 5

我试了,还是不行,JDK也重新设置了,错误还是一样~~~~~~~

Answer 6

听火龙果的，不要用内置的tomcat。楼主可以把<constant name="struts.devMode" value="true" />去掉试试

Answer 7

我解决了,外带的tomcat安装时不能有空格~~~~~~~~
