send array of data from POJO to JSP - arrays

Question

I had a problem on printing array of data in JSP, heres what happend.
I created a POJO called: popArayCustOrd
public class popAryCustOrd {
public String prodkey,descrp,strgth,stkunt;
double rprice;
int quantity;
popAryCustOrd(String prodkey,String descrp,int quantity,Double rprice,String stkunt,String strgth){
this.prodkey = prodkey;
this.descrp = descrp;
this.quantity = quantity;
this.rprice = rprice;
this.stkunt = stkunt;
this.strgth = strgth;
}
public void setProdkey(String prodkey){
this.prodkey = prodkey;
}
public String getProdkey(){
return(this.prodkey);
}
public void setDescrp(String descrp){
this.descrp = descrp;
}
public String getDescrp(){
return(this.descrp);
}
public void setQuantity(int quantity){
this.quantity = quantity;
}
public int getQuantity(){
return(this.quantity);
}
public void setRprice(double rprice){
this.rprice = rprice;
}
public double getRprice(){
return(this.rprice);
}
public void setStkunt(String stkunt){
this.stkunt = stkunt;
}
public String getStkunt(){
return(this.stkunt);
}
public void setStrgth(String strgth){
this.strgth = strgth;
}
public String getStrgth(){
return(this.strgth);
}
}
and in my servlet file called seekprod.java I assigned data coming from the database within a method....
connx.rs.beforeFirst();
while(connx.rs.next()){
popAryCustOrd[] prodList = new popAryCustOrd[]{new popAryCustOrd(connx.rs.getString("prodkey"),connx.rs.getString("descrp"),connx.rs.getInt("quantity"),connx.rs.getDouble("retailp"),connx.rs.getString("stkunit"),connx.rs.getString("strength"))};
request.setAttribute("prodList", prodList);
}
RequestDispatcher dispatcher = request.getRequestDispatcher("preOrdFrm.jsp? inKey="+this.inKey+"&transkey=drugs");
dispatcher.forward(request, response);
.......
and my JSP to access the data is.....
<c:forEach items="${prodList}" var="paramx" >
<tr>
<td>${paramx.prodkey}</td>
<td style="text-align: center; word-wrap: break-word; word-break:break-all; text-overflow: ellipsis;overflow:hidden;white-space: normal; white-space: -webkit-pre-wrap;">${paramx.descrp}</td>
<td>${paramx.stkunt}</td>
<td>${paramx.strgth}</td>
<td>${paramx.rprice}</td>
<td>${paramx.quantity}</td>
<td><input type="hidden" name="agentId" value="<%=uID %>">
<input type="hidden" name="pcode" value=${paramx.prodkey}>
<input type="hidden" name="inKey" value=${param.inKey}>
<input type="hidden" name="transKey" value="sveOrd">
<input style="font-size:50px; height:55px; width:100px" type="number" name="desqty" min="1" required="" value="1"/></td>
<td><input style="font-size:20px; height:55px; width:100px" type="submit" name="transact" value="Save"/></td>
</tr>
</c:forEach>
eventually it works but I got only one result instead of three records from the database table, my syntax in sql is correct and i checked it many times and compared with the result. I dont know where part of my code to fix. Im very much glad if you could help me .?

while(connx.rs.next()){
popAryCustOrd[] prodList = new popAryCustOrd[]{new
popAryCustOrd(connx.rs.getString("prodkey"),connx.rs.getString("descrp"),connx.rs.getInt("quantity"),connx.rs.getDouble("retailp"),connx.rs.getString("stkunit"),connx.rs.getString("strength"))};
request.setAttribute("prodList", prodList);
}
think about this code it sets and then resets prodList attribute in the request object with every loop execution, so your jsp will recieve only the last value set to prodList.
It would be better to initialize an ArrayList outside the loop and add values to it and then after the loop use that list to set the attribute prodList in request object.
