Data not pipulating into table

Question

Hi sdns,
i have dreated 2 classes:-  1)main
                                        2)sub
<h5>code of main:-</h5>
public class main {
     Collection plist = new ArrayList();
     Connection conn = null;
     Statement st;
     public void get_details()
     try
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");     
conn = DriverManager.getConnection( "jdbc:microsoft:sqlserver://10.10.30.25:1433;databaseName=TrackingSystem","sa","sa" ) ;
st = conn.createStatement();
String str = "select * from [Project Table]";
ResultSet rs = st.executeQuery(str);          
String a = rs.getString(1);
String b = rs.getString(2);
String c = rs.getString(3);
while(rs.next())
pdetails rec = new pdetails();
rec.setEname(a);
rec.setRname(b);
rec.setDid(c);
plist.add(rec);
catch(Exception e)
public Collection getPlist() {
return plist;
public void setPlist(Collection collection) {
plist = collection;
<h3>code of pdetails</h3>
public class pdetails {
private String Ename;
private String Rname;
private String Did;
public pdetails()
Ename = new String();
Rname = new String();
Did = new String();
public pdetails(String Ename,String Rname,String Did)
this.Ename = Ename;
this.Rname = Rname;
this.Did = Did;
public String getDid() {
return Did;
public String getEname() {
return Ename;
public String getRname() {
return Rname;
public void setDid(String string) {
Did = string;
public void setEname(String string) {
Ename = string;
public void setRname(String string) {
Rname = string;
I have created a jar file for this classes And imported as a model in my web Dynpro Application.
And mapped it to component controller.
And from there to view controller.
I had a view with a table .
I created the table by using template of table.
And Binded it to the context of the view.
And the code i have written in the WDDOINIT() method is:-
IWDMessageManager msg = wdComponentAPI.getMessageManager();
try
Collection c;
c= new ArrayList();
main m = new main();
m.get_details();
c = m.getPlist();
wdContext.nodePdetails().bind(c);
wdContext.nodePdetails().invalidate();
catch (Exception e) {
// TODO: handle exception
msg.reportWarning("Sorry");
But data is not getting populated in my table.Anything i have to add to my code.
Or else have i done anything wrong in my code
Please help me in this Regard.

Answer 1

What I mean is replace these 2 lines:
wdContext.nodePdetails().bind(c);
wdContext.nodePdetails().invalidate();
with this code:
wdContext.nodePdetails().invalidate(); // erase previous search results
for (int i=0; i<c.size(); i++) { //iterate
SomeObject o = (SomeObject) c.get(i);  // store record in temp variable
PdetailsElement e = wdContext.nodePdetails.createPdetailsElement(); //create context element
e.setPropA(o.getPropA()); // set properties of context element
etc. // set properties of context element
wdContext.nodePdetails.add(e); // add context element to context node
I assume that you have bound the table to nodePdetails, andt that this node has cardinality 0..n.
Also, the elements of this node contain the 3 strings that you want to display in the table.
So when you iterate over the collection that is the result of your query,
you create a new element of the context structure (Pdetail) and set the 3 string values.
Finally add each context element that was created to the context node (add).
Hope this helps, good luck.
