Answer 1

在页面中访问http://localhost:8080/test/test.do时报的错。。不知道什么原因

Answer 2

整合时可能导入的jar包有问题

Answer 3

配置文件相关代码<action path="/jspmanagementcollagedgetslList" parameter="method" method="testdo"
type="com.mdcl.cmcc.managementCollege.util.dong.action.DgetslAction">
<forward name="dsl"
path="/jsp/dong/dsl.jsp">
</forward>
</action>

Answer 4

public ActionForward execute(ActionMapping arg0, ActionForm arg1, ServletRequest arg2, ServletResponse arg3) throws Exception {
// TODO Auto-generated method stub
System.out.println("aciton execute");
return super.execute(arg0, arg1, arg2, arg3);
} //获取金额类型
public ActionForward showTypeOfMoney(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws NotFoundModuleException, ExpiryException, LicenseException{
System.out.println("test /jsp/managementcollage/dgetslList.aciton1");
try {
DgetIsListDAO dilistdao =  (DgetIsListDAO)getBusinessService(DgetIsListDAO.class.getName());
//dilistdao.getTypeOfMoney(null);
} catch (Exception e) {
e.printStackTrace();
}
response.setContentType("text/xml;charset=UTF-8");
//service
IslreadService service = (IslreadService)this.getBusinessService(IslreadService.class.getName());
List xlist = service.getTypeOfMoney(null);
List tempList = new ArrayList();
tempList.add("www");
tempList.add("bbb");
tempList.add("ccc");
tempList.add("ddd");
request.setAttribute("testi", "123");
//StringBuilder xml = new StringBuilder();
try {
response.setContentType("text/html;charset=UTF-8");
ServletOutputStream sertlvetOutputStream1 = response.getOutputStream();
sertlvetOutputStream1.write(tempList.toString().getBytes("utf-8"));
sertlvetOutputStream1.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("test /jsp/managementcollage/dgetslList.aciton2");



return null;
}

public ActionForward testdo(){
System.out.println("testdo");
return null;
}action中的相关代码
忘了strut的配置文件怎么写了。是不是配置文件处问题了啊
