struts问题

---------------------
quote:
我的Form中有VO一个company（其中有一个companyName String型属性）对象及一个companyName String型属性当我jsp中如下时，正常
<html:text  property="compnayName"/>
但当我这样写是就说找不到get,set方法
<html:text  property="company.compnayName"/>
---------------------------------
不知道你是要干什么，<html:text property="compnayName"/>这是生成一个文本框，类似于
html中的<input type="text" name="compnayName">，你可以在struts-config.xml文件找到你的这个FormBean里面肯定有个
  <form-bean name="*" type="org.apache.struts.validator.DynaValidatorForm">
            <form-property name="compnayName" type="java.lang.String" />
  </form-bean>
配置文件是和你界面上显示的是对应的，这样以后就可以在action里面用
String compnayName = form.getString("compnayName");得到你输入的值，
如果你Struts-config.xml里面字段属性是compnayName，那么你的
<html:text  property="company.compnayName"/>是错误的。如果你想给这个文本框绑定值，那么你首先必须定义一个对象，也就是所谓的pojo，这个里面字段必须有get,set方法，不然就会报你说的这个错误，没有set和get方法。然后你在你的jsp页面里面通过执行action的传过来的值，定一一个bean,然后在用bean里面的字段。
举例：..
public abstract class AbstractTeacher  implements java.io.Serializable {
    // Fields         private String pk;
     private String name;
     private String isntavile;
    // Constructors    /** default constructor */
    public AbstractTeacher() {
    }
    /** full constructor */
    public AbstractTeacher(String name, String isntavile) {
        this.name = name;
        this.isntavile = isntavile;
    }
    // Property accessors    public String getPk() {
        return this.pk;
    }

    public void setPk(String pk) {
        this.pk = pk;
    }    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }    public String getIsntavile() {
        return this.isntavile;
    }

    public void setIsntavile(String isntavile) {
        this.isntavile = isntavile;
    }
public class Teacher extends AbstractTeacher implements java.io.Serializable {    // Constructors    /**
*
*/
private static final long serialVersionUID = 1L;
/** default constructor */
    public Teacher() {
    }
    /** full constructor */
    public Teacher(String name, String isntavile) {
        super(name, isntavile);
    }

}
假如我有一个action叫做
findTeacher.do
里面写了一些这样的代码
....
Teacher t = teacherDAO.findByName("张三");
request.setAttribute("zs",t);
然后转到disDetailTeacher.jsp页面
<html>
<body>
...
   <bean:define id="teacher" name="t"/>
   //这个bean里面的name属性就是你action里面传过来的，他是一个Teacher对象
   //如果你要显示就可以如下方式
   <html:text property="name" value="${teacher.name}"/>
   //或者这样也行
   <html:text property="name" value="<bean:write name='teacher' properyt='name'/>"/>
   //如果你的Teacher对象里面没有定义name的get和set方法，那么就会报找不到get,set方法
</body>
</html>
首先谢谢楼上详细的讲解
其实我没有用象你这样
我用struts还属于学习状态，用struts用得比较简单
我的配置是这样的
  <form-beans>
    <form-bean
      name="companyForm"
      type="com.owenlin.business.web.action.company.CompanyForm"
    />
  </form-beans>
<action
      path="/saveCompany"
      type="com.owenlin.business.web.action.company.CompanyAction"
      name="companyForm"
      scope="request"
      input="failure"
      unknown="false"
      validate="false"
    >
      <forward

companyForm中的companyName只是我做测试用的
我本来想只要一个company对象就行了
这样action就好简单，接收jsp传来的company对象就往后台程序service扔就行了我原来也有一些struts开发经验，是在一个大项目中，很多配置工作别人都做好了。现在也有半年没有搞程序了，我记得当时的jsp文件是就写company.companyName就可以了最近又想找工作，才自己一个人练练，没想到遇到很多问题，其实是因为很多东西自己没有亲手试过，在大项目中就一个代码工人，呵呵
很久以前贴子，原电脑支持javascript有问题，所以再在才结，答案我自己发现了，是在form中初始化要 new 一个companycompanyForm：
public class CompanyForm extends BaseForm {
private String action;
private Company company=new Company;  //就这样
private String compnayName;
private String description;很简单的问题，搞了很久，后来找了原来的代码看了看，就发现了
