Cursor Focus for OAF Mobile Pages

OA Pages can be rendered in PDA or Mobile devices without doing special coding. Generally hand held devices are used in shop floor, warehouses or for some field work. And the keypad of a mobile device will be small and it is difficult to use navigation buttons. So we must design the User Interface in such way to minimize button clicks and user interventions. User would love a page where he simply has to scan the labels in shop floor and may be press a single button at the end to confirm the transaction. For such an user friendly UI it is mandatory to focus the cursor on the scan field. But javaScript is completely disabled if the device (agent) is PDA/Mobile. Even
OABodyBean.setInitialFocusId() wont work in mobile. We did the following to get the cursor focus on mobile page (11.5.10 RUP3).

a. Copy OA.jsp to XXOAMobile.jsp
b. Modify the following code in XXOAMobile.jsp

Old Code
try
{
redirectURL = pageBean.preparePage(pageContext);

if (redirectURL != null)
{
%>
<jsp:forward page="<%= redirectURL %>" />


New Code
try
{
redirectURL = pageBean.preparePage(pageContext);

if (redirectURL != null)
{
String x = redirectURL.substring(2); // modified
x= "XXOAMobile" + x; // modified
%>
<jsp:forward page="<%= x %>" />



c. Seed your AOL Menu function with WEB HTML Ref as XXOAMobile.jsp?page=<Func Name> instead of OA.jsp?page=<Func Name>

d. In your CO's always do a setForwardURL to XXOAMobile.jsp?page=<Func Name>

e. Add the java script code in XXOAMobile.jsp
WARNING: This code is definetely not upgrade safe and we must revisit it after every tech stack upgrade.
