/******* class CA **********/
public class CA FormData

private String AID;
private String AName;
public CB[] cb;

public void setAID (String value) { this.AID= value;}
public void setAName (String value) { this.AName= value;}
public void setCB (CB[] value) { this.cb= value;}

public String getAID (){ return this.AID;}
public String getAName (){ return this.AName;}
public CB[] getCB (){ return this.cb;}
}
/********* Class CB ***********/
public class CB implements Serializable
{
private String BID;
private String BText;
private boolean select;

public void setSelect(boolean value){this.select = value;}
public void setBID (String value) { this.BID= value;}
public void setBText (String value) { this.BText= value;}

public String getBID (){ return this.BID;}
public String getBText (){ return this.BText;}
public boolean isSelect(){return this.select;}
}

/****** pageA.jsp *********/
