struts+tomcat配置问题

Question

我从按照网上的说明，把struts-examples.war文件拷贝tomcat下面的webapps下面，运行这个struts-examples/welcome.do，照网上说，就可以看到那个struts的例子的画面了，可我怎么没有显示。我的tomcat其它目录下的jsp文件都可以运行的，这个怎么不行呢，是不是还有什么其他地方需要修改的呢，我的tomcat是5.0的。struts-1.2的：页面报错如下：HTTP Status 500 -

Answer 1

我感觉是.xml文件路径没配好，仔细检查一下

Answer 2

晕，这个还是从apache上面down下来的，

Answer 3

可能是weclome.jsp里面开头那个<%@  taglib uri="/WEB-INF/struts-html.tld"   prefix="html" %  >错误了，可是标签库不这么注明，还有其他方法吗？那个"/WEB-INF/struts-html.tld"也在web.xml里面定义了啊。struts-html.tdl所需的class在lib那个包里面存在的,就是怎么还报那个错误呢

Answer 4

我的也出错了,其它都和你一样,但原因和你不太一样

Answer 5

前段时间刚发生过
struts.jar这个包放在多个地方可能会发生冲突，建议只把struts.jar这个包放在工程目录的lib目录下，象tomcat的lib，jre的ext目录都不要放
