Refreshing data after insert

Question

I am using jsp + bc + adf (jdev 10g). When I insert a record with sql:update (see the code below) the trigger on the database updates another table. Insert works fine and I can see the inserted record but I don't see the changes made by the trigger until I open the browser again. Can I do something about that?
<sql:setDataSource
var="ds"
driver="oracle.jdbc.driver.OracleDriver"
user="user"
password="password"
url="jdbc:oracle:thin:@..."
/>
<sql:update dataSource="${ds}">
Insert into sometable values (..., ..., ...)
</sql:update>

Answer 1

It is because I am trying to insert a record without dropping a create method on a datacation. I am trying with the code below but getting error messages.
Is there something I can do about this?
DataAction.java
package view;
import javax.servlet.http.HttpServletRequest;
import oracle.adf.controller.struts.actions.DataAction;
import oracle.jbo.ApplicationModule;
import oracle.jbo.Row;
import oracle.jbo.domain.Number;
import oracle.jbo.ViewObject;
import org.apache.struts.action.ActionForward;
import oracle.adf.controller.struts.actions.DataActionContext;
import java.io.IOException;
import javax.servlet.ServletException;
public class InsertZauprocDAAction extends DataAction
protected ActionForward findForward(DataActionContext actionContext) throws IOException, ServletException
ApplicationModule appModule = actionContext.getBindingContainer().getApplicationModule();
ViewObject viewObject = appModule.findViewObject("ZauprocView1");
HttpServletRequest request = actionContext.getHttpServletRequest();
Row row = viewObject.createRow();
row.setAttribute("IZA", request.getParameter("Iza"));
row.setAttribute("IZVRSIOC", request.getParameter("Izvrsioc"));
row.setAttribute("STATUS", new Number(200));
viewObject.insertRow(row);
appModule.getTransaction().commit();
return super.findForward(actionContext);
error
