How to JDeveloper memory settings

Before, Did you get warning message the "Low memory warning" on JDeveloper .

I will describe how to fix it. There are two config files on jdeveloper installation directory.
the first one is jdev.conf file. the file located in \jdeveloper\jdev\bin
increase the memory values for the following parameters:
AddVMOption -XX:MaxPermSize=1024M

the second one is ide.conf file on \jdeveloper\ide\bin.

AddVMOption -Xmx1024M
AddVMOption -Xms1024M

For now start JDeveloper. if jdeveloper can not start, decrease memory allocated values and retry to start jdeveloper

ADF Query Component Usage with ADF Panel Stretch Layout

There is a very nice layout component in ADF 11g - af:panelStretchLayout (ADF Panel Stretch Layout). This component comes with 5 facets - Bottom, Center, End, Start and Top. It allows to split your page layout in more easy way - you can put menu component into Top facet, functional logic into Center facet.

Everything seems okej and clear, however there is hidden issue when you need to have menu elements in Top facet dependent on ADF Query from Center facet. For example, menu item can be enabled/disabled based on ADF Query results:

JDeveloper 11g and ADF Task Flow Parameters

Developed sample application - is based on standard HR schema, Departments and Employees entities. Unbounded task flow contains selectDepartments page and call to separate bounded task flow. Bounded task flow contains employees page and Task Flow Return component, this component allow to return to calling ADF Task Flow.

When I was creating this application, I have used Fusion Web Application (ADF) as a template for developed sample application. Empty unbounded task flow was created automatically - adfc-config.xml. My next step was to create bounded task flow - task-flow-definition.xml:

Create, Edit and Delete operations in ADF Faces af:table component

Developed sample application, provides read-only table with those actions - Delete, Create, Edit, Save, Cancel. Row selected for editing is shown in editable mode and can be updated. Application is based on HR schema that comes with Oracle XE database. Application logic is based on Jobs entity from HR schema.
This sample is developed using the same principle as described in my previous post. I will describe what are the differences in implementation:

Passing Parameters from ADF Task Flow with Fragments into ADF Bounded Task Flow

It is a common use case to pass parameters from ADF Task Flow with fragments into another ADF Task Flow without fragments. I got this question for my previous blog post - Parent Action Activity in ADF Task Flow. The use case:

1. We have ADF Bounded Task Flow, it contains two main elements - page P1 and another ADF Task Flow call - C1
2. Page P1 included ADF region, this region comes from ADF Task Flow with Fragments
3. We need to pass parameter from ADF region available in P1 into ADF Task Flow call C1

ADF Task Flow in JDeveloper 11g

In JDeveloper 10g there is only one possibility to design application page flow structure - using JSF navigation flows. But sometimes, use cases require to implement complex page flow, that is not supported by JSF navigation flows. JDeveloper 11g brings ADF task flows in addition to JSF navigation flows. From Oracle JDeveloper 11g Technology Preview, Fusion Developer's Guide for ADF:

Task flows provide a more modular and transactional approach to navigation and application control. Like standard JSF navigation flows, task flows mostly contain pages that will be viewed. However, instead of describing navigation between pages, task flows facilitate transitions between activities. Aside from navigation, task flow activities can also call methods on managed beans, evaluate an EL expression, or call another task flow, all without invoking a particular page. This facilitates reuse, as business logic can be invoked independently of the page being displayed.

TrackQueryPerformed Property Usage and ADF Task Flows

I will describe following scenario - two ADF Task Flows, second ADF Task Flow is opened as Isolated. First ADF Task Flow provides query functionality implemented as View Criteria, and second ADF Task Flow accepts current row key value and allows to edit data. Scenario is pretty simple, and can be implemented in Oracle ADF very fast. However, there is one trick if you open second ADF Task Flow as Isolated. I will describe it and provide solution.

PopUpFetch Option for Property Listener

With previous JDeveloper/ADF 11g releases it was quite complicated to catch popup fetch event, we were overriding popup fetch listener inside managed bean and processing it. Its a good hint, things are simpler now - there is popupFetch property with Set Property Listener component:click here detail read post
