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 - TaskFlowParamaters.zip 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:
