解决方案
解决方案二：
相关代码：struts配置：<actioninput="/Login.jsp"name="workerForm"parameter="login"path="/login"scope="request"><forwardname="manager"path="/ManIndex.jsp"/><forwardname="client"path="/CliIndex.jsp"/><forwardname="manager_fund"path="/fund/ManIndex.jsp"/><forwardname="client_fund"path="/fund/CliIndex.jsp"/></action>spring配置：<beanname="/login"class="com.erayt.treasure.action.WorkerAction"autowire="byName"/>java类：publicActionForwardlogin(ActionMappingmapping,ActionFormform,HttpServletRequestrequest,HttpServletResponseresponse){try{....}catch(ApplicationExceptione){}returnmapping.getInputForward();}
解决方案三：
<actioninput="/Login.jsp"name="workerForm"parameter="login"path="/login"scope="request"type="org.springframework.web.struts.DelegatingActionProxy">你试试
解决方案四：
你写的不规范，一个类的类名首字母要大写，还有检查一下配置文件里的文件头<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEstruts-configPUBLIC"-//ApacheSoftwareFoundation//DTDStrutsConfiguration1.2//EN""http://struts.apache.org/dtds/struts-config_1_2.dtd">
解决方案五：
<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEstruts-configPUBLIC"-//ApacheSoftwareFoundation//DTDStrutsConfiguration1.2//EN""http://struts.apache.org/dtds/struts-config_1_2.dtd">配置文件没有问题，会不会是包的问题我jdbc驱动是ojdbc14.jar大哥谢谢再帮忙看看。。
解决方案六：
我认为和jdbc没啥关系，现在是你无法创建action你去这里看看别人的解决方案：http://ajava.org/exep/myeclipse/14249.html
解决方案七：
大哥，这个我看过了我的项目在tomcat下是正确的不报错啊
解决方案八：
我要结贴。。。来顶哈。。
解决方案九：
该回复于2011-03-10 15:14:49被版主删除
解决方案十：
websphere的JVM用的是IBM的什么版本？可能是版本的问题。我之前用的IBM1.4。需要修改程序里一些配置和代码符合jdk1.4的要求。
