Hi.
Im developing a web application at work using Struts2, Hibernate and Spring.
I have two classes with a parent/child (PCB - BrgpInfo) relation and i make
one JSP page to insert data to populate this 2 classes. The problem is that
i can read all the information but i cant insert data to the Set<BrgpInfo>.
[B]Pcb.java[/B]
[CODE]
import java.io.Serializable;
import java.util.Iterator;
import java.util.Set;
public class Pcb implements Serializable{
private static final long serialVersionUID = 5925233207935081072L;
/* Primary Key */
private int id;
/* Properties */
private String serialNumber;
private String origem;
/* Procedure information */
private FailInfo failInfo;
//private ClientInfo clientInfo;
/* Lista de BrgP info */
private Set<BrgpInfo> brgpInfos;// = new HashSet<BrgpInfo>();
//private List<BrgpInfo> brgpInfos = new ArrayList<BrgpInfo>();
public Pcb() {
super();
// TODO Auto-generated constructor stub
}
public Pcb(int id){
this.id = id;
}
public Pcb(int id, String serialNumber, String origem, FailInfo failInfo,
Set<BrgpInfo> brgpInfos) {
super();
this.id = id;
this.serialNumber = serialNumber;
this.origem = origem;
this.failInfo = failInfo;
this.brgpInfos = brgpInfos;
}
public Set<BrgpInfo> getBrgpInfos() {
return brgpInfos;
}
public void setBrgpInfos(Set<BrgpInfo> brgpInfos) {
this.brgpInfos = brgpInfos;
}
public FailInfo getFailInfo() {
return failInfo;
}
public void setFailInfo(FailInfo failInfo) {
this.failInfo = failInfo;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getOrigem() {
return origem;
}
public void setOrigem(String origem) {
this.origem = origem;
}
public String getSerialNumber() {
return serialNumber;
}
public void setSerialNumber(String serialNumber) {
this.serialNumber = serialNumber;
}
}

[B]BrgpInfo.java[/B]
[CODE]import java.io.Serializable;
public class BrgpInfo implements Serializable{
private static final long serialVersionUID = -1848147187786536525L;

private String pcbN;
//private int pcbId;
private Pcb pcb;
public BrgpInfo() {
super();

}
public BrgpInfo(int id){
this.id = id;
}
/*Constructor necess??rio para a rela????o one-to-many*/
public BrgpInfo(Pcb pcb){
setPcb(pcb);
}
public BrgpInfo(int id, String receptDate, String controlN, String pcbN,
Pcb pcb) {
super();
this.id = id;
this.receptDate = receptDate;
this.controlN = controlN;
this.pcbN = pcbN;
this.pcb = pcb;
}
public String getControlN() {
return controlN;
}
public void setControlN(String controlN) {
this.controlN = controlN;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;

public Pcb getPcb() {

My JSP it's this:
[CODE]
<s:form method="post" action="done">
<!--PCB -->
<h4>Serial Number</h4>
<s:textfield name="pcb.serialNumber" cssClass="registration_text"/> <br/>
<h4>Origem</h4>
<s:textfield name="pcb.origem" cssClass="registration_text"/> <br/>
<!--BRGPINFO DATA -->
<h4>Recept Date</h4>
<s:textfield name="pcb.brgpInfos.receptDate"/><br/>
<h4>Control Number</h4>
<s:textfield name="pcb.brgpInfos.controlN"/><br/>
<h4>Pcb Number</h4>
<s:textfield name="pcb.brgpInfos.pcbN"/><br/>
[/CODE]
To read data from the Set i use the <s:iterator> tag and work just fine.
What i need to do to insert?
