我的解決辦法是將D:/Program Files/MyEclipse 6.0
/eclipse/plugins/com.genuitec.eclipse.cross.easystruts.eclipse_6.0.0.zmyeclipse60020070820/data/1.2
/lib/struts.jar包拷貝到{TOMCAT}/common/lib下，然後重新啓動服務器。
可能的原因：（不妨多試試，總能找到辦法的）我找的幾個寫的：不煩看看
1.轉載自：http://www.rainsts.net/article.asp?id=229
當在 tomcat 中運行 struts 出現 "org.apache.jasper.JasperException: ..." 錯誤時，可以試着將 {Project}
/WEB-INF/lib/struts.jar 拷貝到 {TOMCAT}/common/lib。或許還需要重啓 tomcat。
