Display data in Web DynPro table from database via EJB

Question

I have a JavaBeans model which has a method populateDataToTable()to retrieve data from database via Session bean (calling entity bean, returning ArrayList of data) and the data needed to be display in the Web DynPro table.
User Interface (Web DynPro) <-> JavaBeans Model <-> Busineess Logic (session bean) <-> Persistence (Entity Bean)<-> DB table.
The context bindiing and table part is ok. How do i load the data to the table ? what the coding to put in wdDoInit() ?
Any help would be appreciated.

Answer 1

in wdinit(),
Collection col = new ArrayList();
try{                    
  MyCommandBean bean = new MyCommandBean();
  col = bean.getDataFromDbViaEJB();
  wdContext.nodeMyCommandBean().bind(col);
} catch (Exception ex) {
   ex.printStackTrace(ex); 
in your JavaBean model class, MyCommandBean getDatafromDbViaEJB() method:
Collection col = new ArrayList();
Collection newcol = new ArrayList();
//include your own context initialization etc...
col = local.getDataViaSessionBean(param);
// if your returned result also a bean class, reassigned it to current MyCommandBean
for (Iterator iterator = col.iterator(); iterator.hasNext();) {
    MyOtherBean otherBean=(MyOtherBean)iterator.next();
    MyCommmandBean bean = new MyCommandBean();
    bean.attribute1 = outBean.getAttirbute1();
    // get other attibutes
    newcol.add(bean);
return newcol;
