08-How to invoke Application Module Impl Java file's method from Controller Java File in Oracle OAF?
Suppose we have the below method in our Application Module Impl file:
public void filterOrder(String orderNumber,String orgName){
//Get Handle of the view object
ManualSearchVOImpl manualSearchVo=getManualSearchVO();
//Set where clause to the view object
manualSearchVo.setWhereClause("order_number = nvl(:1,order_number) and org_name = nvl(:2,org_name) ");
//Set the where clause parameters
manualSearchVo.setWhereClauseParam(0,orderNumber);
manualSearchVo.setWhereClauseParam(1,orgName);
//Execute this where clause now
manualSearchVo.executeQuery();
}
Note: Here ManualSearchVO is added to the application module
To run this method from Controller File use the below code.
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean) {
super.processFormRequest(pageContext, webBean);
OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
//Below code will be executed when GoBtn is clicked
if (pageContext.getParameter("GoBtn") != null) {
String orderNumber = pageContext.getParameter("OrderNumberTxt");
String orgName = pageContext.getParameter("OrgNameTxt");
//Serialize the parameters to send to Application Module Impl file
Serializable params[] = { orderNumber, orgName };
//Call the Application Module Impl file's function
am.invokeMethod("filterOrder", params);
}
}
