How to loop through the VO Rows in ADF

Hi,

In this example we will make use of a simple button to invoke a method in AM and in that method we will loop through the VO Rows. The same can be utilised in noumerous situations where you need to loop through the VO Rows as the page submits.

Step 1) Write a method loopVORows in Application Module

public void loopVORows ()
{
ApplicationModule am = (ApplicationModule) Configuration.createRootApplicationModule("sapient.oracle.model.InvoiceAM","InvoiceAMLocal");
InvoiceVOImpl vo = (InvoiceVOImpl) am.findViewObject("InvoiceVO1");
if(vo!=null)
{
for (InvoiceVORowImpl row = (InvoiceVORowImpl) vo.first(); row!=null;row = (InvoiceVORowImpl) vo.next())
{
System.out.println("Invoice Number is "+row.getInvoiceNum());
}
}
}




Step 2) Double Click on Application Module and under Client Interfaces shuttle the method defined above in the avaliable methods for client.









Step 3) Referesh the DataControl so as to reflect the new method and then drag and drop the new method from the datacontrols to the JSF page and create a ADF Button.








Step 4) Run the page. The output will look like :





Step 6) Click on the button and in the jdev console you will see the SOP printed.

Time Zone Region not found : Error in ADF

Hi,

This has been very common error faced during development.

So, in order to get rid of this error, instead of setting the project properties and modifying the Debug/Run/Profile for each of the project we can set the Java options at default project properties so that it gets reflected for every project we create within jdev 11g and we would not need to edit the properties again n again for each project.

The steps to do that are :

1) Click on Application at the Top Bar in jdev 11g and select Default Project Properties.




2) click on Edit and set the proper timezone.






Don't forget to close and re open the jdev 11g to reflect the changes.
