Implementing Component Reference in ADF

There is a lot of confusion about how to use ADFcomponent binding in managed beans in a clustered environment to meet high availability.
UI Components are not serializable in ADF, so your application might fail to work correctly in a clustered environment.
So we need to implement Component Reference in backing beans .
This will be useful only in case of managed bean which is in a scope greater than requestScope or backingBeanScope.

Actual Backing Bean Bindings
-----------------------------------------------
    private RichCommandLink commandButton;

    public void setPagiCommand(RichCommandLink commandButton) {
        this.commandButton= commandButton;
    }

    public RichCommandLink getCommandButton() {

        return commandButton;
    }

ComponentReference Implementation
-----------------------------------------------
    private ComponentReference commandButton;

    public void setPagiCommand(RichCommandLink commandButton) {
        this.commandButton = ComponentReference.newUIComponentReference(commandButton);
    }

    public RichCommandLink getCommandButton() {
        if(commandButton!=null)
            return (RichCommandLink)commandButton.getComponent();
        return null;
    }

Programatically Calling Hidden Button Action

If you want to call a hidden button action from another button action/event use below code

private void navigateByQueueAction() {
   FacesContext fctx = FacesContext.getCurrentInstance();
   UIViewRoot root = fctx.getViewRoot();
   //client Id of button includes naming container like id of region.
   RichCommandButton button =
           (RichCommandButton) root.findComponent("r1:cb3");
   ActionEvent actionEvent = new ActionEvent(button);
   actionEvent.queue();
}

oracle.stellent.ridc.protocol.ServiceException: Unable to retrieve search results. Unable to parse date

ISSUE:
oracle.stellent.ridc.protocol.ServiceException: Unable to retrieve search results. Unable to parse date '10/11/11 12:00 AM'.
     at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:135)
     at oracle.stellent.ridc.protocol.ServiceResponse.getResponseAsBinder(ServiceResponse.java:107)

Solution:

To resolve this issue we have to change date format to yyyy-MM-dd hh:mm:ss

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String lastModifiedFromDate=sdf.format(lastDate);
            if (lastModifiedFromDate!= null) {
                if ("".equalsIgnoreCase(queryString))
                    queryString= queryString+ "xmodifiedDate>=`" + lastModifiedFromDate + "`";
                else
                    queryString =queryString + "<AND>" + "xmodifiedDate>=`" + lastModifiedFromDate +"`";
            }

Uploading Large Files from ADF 11g Applications

In ADF upload component if we want to increase upload file size we have to keep below code in web.xml.

<context-param>
<param-name>org.apache.myfaces.trinidad.UPLOAD_MAX_DISK_SPACE</param-name>
<param-value>20971520</param-value>
</context-param>

if we set adf instead of apache that use to throw "The file could not be uploaded because it is too large" error on upload component.
