struts的No getter method问题

Question

我在做下拉列表动态绑定是发生了No getter Method的错误，在form中，不是大小写的问题，上网查了一些资料，出的问题也和我不一样，急救啊！！！
jsp中代码如下：
<html:select property="choose">
  <html:option value="0">------请选择------</html:option>
<html:optionsCollection name="bugRoleList" label="userRoleName" value="userRoleId" />
</html:select>
form中代码如下：
public class MissionForm extends ActionForm {
/**
 * 
 */
private static final long serialVersionUID = 1L; /*
 * Generated Methods
 */
private String misUserChoose;

private String choose;

private String misRoleChoose;

private String rwId; private XtYh xtYh; private String dyName;

private DyJq dyJq; private RwSp rwSp; private Integer rwState; private Date rwDate = new Date(); private Set xtQxes = new HashSet(0);

public DyJq getDyJq() {
return dyJq;
} public void setDyJq(DyJq dyJq) {
this.dyJq = dyJq;
} public Date getRwDate() {
return rwDate;
} public void setRwDate(Date rwDate) {
this.rwDate = rwDate;
} public String getRwId() {
return rwId;
} public void setRwId(String rwId) {
this.rwId = rwId;
} public RwSp getRwSp() {
return rwSp;
} public void setRwSp(RwSp rwSp) {
this.rwSp = rwSp;
} public Integer getRwState() {
return rwState;
} public void setRwState(Integer rwState) {
this.rwState = rwState;
} public Set getXtQxes() {
return xtQxes;
} public void setXtQxes(Set xtQxes) {
this.xtQxes = xtQxes;
} public XtYh getXtYh() {
return xtYh;
} public void setXtYh(XtYh xtYh) {
this.xtYh = xtYh;
} /** 
 * Method validate
 * @param mapping
 * @param request
 * @return ActionErrors
 */
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
// TODO Auto-generated method stub
return null;
} /** 
 * Method reset
 * @param mapping
 * @param request
 */
public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
} public String getDyName() {
return dyName;
} public void setDyName(String dyName) {
this.dyName = dyName;
} public String getMisRoleChoose() {
return misRoleChoose;
} public void setMisRoleChoose(String misRoleChoose) {
this.misRoleChoose = misRoleChoose;
} public String getMisUserChoose() {
return misUserChoose;
} public void setMisUserChoose(String misUserChoose) {
this.misUserChoose = misUserChoose;
} public String getChoose() {
return this.choose;
} public void setChoose(String choose) {
this.choose = choose;
}
}
其中，get和set方法都是自动生成的，大小写都符合要求，查询出的list没有问题,我试过了，如果不用form中的choose属性，换用form中的dyName属性，就没有问题了，郁闷中，为什么同一个form中的属性使用另外一个就可以了呢？急救啊！！！！

Answer 1

删除tomca主目录下/work/Catalina所有文件，重新测试。
放心，该目录课放心删除，测试时自动生成。
reseon：
   你上次修改的文件混淆了编译器。

Answer 2

<html:optionsCollection name="bugRoleList" label="userRoleName" value="userRoleId" />
list的对象是什么，是不是没有userRoleName或userRoleId的get方法

Answer 3

删除tomcat主目录下的/work/Catalina 下所有文件.
再重新启动服务器试试
不行的话把错误信息贴出来应该。

Answer 4

我把tomcat主目录下的/work/Catalina 的文件都删除了，可是还是不行啊，我的bugRoleList中存的是查询一张但表的的对象，对象中的userRoleName和userRoleId的get方法是肯定有的，错误代码如下：

一头的汗啊

Answer 5

就是说你没有get,set方法,或者你名字写错了..
