请帮我摆脱这个小错误。。我是jsf的新手，所以我对基本的东西很不熟悉。。。
提前感谢：-）
这是我的后盾。。。
导入javax.faces.bean.ManagedBean
@ManagedBean(name = "objcetMapBean")

public class ObjectMapGossip {
private SearchCrew1 searchCrewParam = new SearchCrew1("212","kart","asd");

public SearchCrew1 getSearchCrewParam() {
    return searchCrewParam;
}

public void setSearchCrewParam(SearchCrew1 searchCrewParam) {
    this.searchCrewParam = searchCrewParam;
}

public String search() {
    return "success";
}

}

class SearchCrew1 {

public SearchCrew1() {
    super();
}
 /**
 * @param staffNum
 * @param surName
 * @param rank
 */
public SearchCrew1(String staffNum, String surName, String rank) {
    super();
    this.staffNum = staffNum;
    this.surName = surName;
    this.rank = rank;
}

private String staffNum;

private String surName;

private String rank;

public String getStaffNum() {
    return staffNum;
}

public void setStaffNum(String staffNum) {
    this.staffNum = staffNum;
}

public String getSurName() {
    return surName;
}

public void setSurName(String surName) {
    this.surName = surName;
}

public String getRank() {
    return rank;
}

public void setRank(String rank) {
    this.rank = rank;
}

}
这是我的jsf页面

我们可以使用jsf标记中的h:dataTable并轻松映射。
