怎样引进Struts工具，谢谢！

开发环境 window2000+jbuilder7+tomcat4.1.12   首先，从http://jakarta.apache.org下载jakarta-struts-1.0.2.zip，解开后有两个主要目录lib和webapps，在lib目录中是使用struts创建应用程序所必需的文件,在webapps目录下有几个后缀是war的文件，熟悉java web开发的人都比较清楚，将他们copy到tomcat/ webapps/目录下，然后再重新启动tomcat，tomcat会将这些web工程部署好的，其中Struts-document．tion.war是文档，Struts-example.war是一个不错的例子，我主要就是参考这个例子来做的。然后在jbuilder安装目录/lib/下建立 struts目录，将上面的lib目录下的东西copy进去，然后启动jbuilder7,运行菜单tools->configure->libraries->new->name  输入struts,然后选择刚才copy过去的struts.jar文件,然后OK。   其次，新建立一个工程，引用struts，服务器选择tomcat4，然后建立一个Jsp1.jsp文件，然后把lib/目录下的所有.tld文件copy到你建立的工程目录下的/defaultroot/WEB-INF/目录下面，在/defaultroot/WEB-INF/建立action.xml,内容如下：<action-mappings>    <forward name="logon"        path="/logon.jsp"/>    <action    path="/logon"      actionClass="example.LogonAction"    formAttribute="logonForm"        formClass="example.LogonForm"        inputForm="/logon.jsp">    <forward name="success"    path="/Jsp1.jsp"/>  </action></action-mappings>struts-config.xml文件，如下：     <?xml version="1.0" encoding="ISO-8859-1" ?><!DOCTYPE struts-config PUBLIC          "-//Apache Software Foundation//DTD Struts Configuration 1.0//EN"          "http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd";><struts-config><form-beans> <form-bean name="logonForm"type="example.LogonForm"/>    </form-beans><global-forwards>    <forward name="logon"   path="/logon.jsp"/></global-forwards><action-mappings> <action    path="/logon"               type="example.LogonAction"               name="logonForm"              scope="request"              input="/logon.jsp">       <forward   name="success"              path="/Jsp1.jsp"/>    </action><action    path="/admin/addFormBean"type="org.apache.struts.actions.AddFormBeanAction"/>    <action    path="/admin/addForward"   type="org.apache.struts.actions.AddForwardAction"/>    <action    path="/admin/addMapping"type="org.apache.struts.actions.AddMappingAction"/>    <action    path="/admin/reload"type="org.apache.struts.actions.ReloadAction"/>    <action    path="/admin/removeFormBean"type="org.apache.struts.actions.RemoveFormBeanAction"/>    <action    path="/admin/removeForward"type="org.apache.struts.actions.RemoveForwardAction"/>    <action    path="/admin/removeMapping"type="org.apache.struts.actions.RemoveMappingAction"/>  </action-mappings></struts-config> 然后建立logon.jsp，内容如下：<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:html locale="true">
<head>
<title><bean:message key="logon.title"/></title>
<html:base/>
</head>
<body bgcolor="white">
<html:errors/>
<html:form action="/logon" focus="username">
<table border="0" width="100%">
  <tr>
    <th align="right">
      <bean:message key="prompt.username"/>
    </th>
    <td align="left">
      <html:text property="username" size="16" maxlength="16"/>
    </td>
  </tr>
  <tr>
    <th align="right">
      <bean:message key="prompt.password"/>
    </th>
    <td align="left">
      <html:password property="password" size="16" maxlength="16" redisplay="false"/>
    </td>
  </tr>
  <tr>
    <td align="right">
      <html:submit property="submit" value="Submit"/>
    </td>
    <td align="left">
      <html:reset/>
    </td>
  </tr>
</table>
</html:form>
</body>
</html:html>
然后建立一个class  LogonForm.java，继承自ActionForm，打包在example内容如下package example;import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;public class LogonForm extends ActionForm {  private String password = null;
  private String username = null;  public String getPassword() {
    return password;
  }
  public String getUsername() {
    return username;
  }
  public void setPassword(String password) {
    this.password = password;
  }
  public void setUsername(String username) {
    this.username = username;
  }  public void reset(ActionMapping mapping, HttpServletRequest request) {        this.password = null;
        this.username = null;    }  public ActionErrors validate(ActionMapping mapping,
                               HttpServletRequest request) {      ActionErrors errors = new ActionErrors();
      if ((username == null) || (username.length() < 1))
          errors.add("username", new ActionError("error.username.required"));
      if ((password == null) || (password.length() < 1))
          errors.add("password", new ActionError("error.password.required"));      return errors;    }
} 然后建立一个class  LogonAction.java，继承自Action，打包在example内容如下package example;import java.io.IOException;
import java.util.Hashtable;
import java.util.Locale;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionServlet;
import org.apache.struts.util.MessageResources;public class LogonAction extends Action {  public ActionForward perform(ActionMapping mapping,
                             ActionForm form,
                             HttpServletRequest request,
                             HttpServletResponse response)
throws IOException, ServletException {        Locale locale = getLocale(request);
//MessageResources messages = getResources();
        ActionErrors errors = new ActionErrors();
        String username = ((LogonForm) form).getUsername();
String password = ((LogonForm) form).getPassword();        // Report any errors we have discovered back to the original form
        if (!errors.empty()) {
            saveErrors(request, errors);
            return (new ActionForward(mapping.getInput()));
        }        // Save our logged-in user in the session
        HttpSession session = request.getSession();
        session.setAttribute("user", "ok");
        if (servlet.getDebug() >= 1)
            servlet.log("LogonAction: User :"  +
                        "' logged on in session " + session.getId());        // Remove the obsolete form bean
        if (mapping.getAttribute() != null) {
            if ("request".equals(mapping.getScope()))
                request.removeAttribute(mapping.getAttribute());
            else
                session.removeAttribute(mapping.getAttribute());
        }        // Forward control to the specified success URI
return (mapping.findForward("success"));
  }
} 然后修改/defaultroot/WEB-INF/web.xml文件为<?xml version="1.0" encoding="UTF-8"?>

         最后还有一个重要的问题，就是一开始我们说过Struts-example.war，安装后把\struts-example\WEB-INF\src\org\apache\struts\webapp\ApplicationResources.properties放到/defaultroot/WEB-INF/classes/example/目录下,然后就可以运行了,当你运行jbuilder后，在IE上键入http://localhost:8080/就会看到效果了，具体的解释请参见下一解释篇刚开始研究struts，所以把自己的经过给大家分享,欢迎大家批评指正
好像得重写execute方法,不是perform,别的不清楚,我也是刚学啊

调试易
