Populating data from model to table

Question

This is the code i have written for populating.
Please verify this code.
Let me know if anything more to be done.
code of main:-
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;
code of pdetails
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();
for(int i = 0; i<c.size();i++)
pdetails pd = new pdetails();
String a = pd.getDid();
String b = pd.getEname();
String f = pd.getRname(); IPrivateProjectDetails.IPdetailsElement proj = wdContext.nodePdetails().createPdetailsElement(pd);
proj.setDid(a);
proj.setEname(b);
proj.setRname(f);
wdContext.nodePdetails().addElement(proj);
catch (Exception e) {
// TODO: handle exception
msg.reportWarning("Exception Caught");

Hi,
Can you put
msg.reportSucces(´bla´);
somewhere inside this loop:
for(int i = 0; i<c.size();i++)
to verify that you actually get data from the backend?
Please let us know if you actually see the messages in your screen.
Good luck, Roelof
