Using Managed Beans with your ADF Mobile Client Applications
- by [email protected]
Did you know it's easy to extend your ADF Mobile Client application with a Managed Bean just like it is with an ADF web application? Here's how:
Using the New Gallery (File -> New), create a new Java class. This class should extend oracle.adfnmc.el.utils.BeanResolver.
Add this java class as a managed bean: Go to your task flow, select the Overview tab at the bottom and go to the Managed Bean section. Add an entry and name your new Managed Bean and point to the java class you just created.
Add your custom methods and properties to your java class
Since reflection is not supported in the J2ME version on some platforms (BlackBerry), you need to provide dispatch code if you want to invoke/access any of your methods/properties from EL. Here's a sample:
MyBeanClass.java
Use Expression Language (EL) to access your properties and invoke your methods on your MCX pages. Here's an sample:
<?xml version="1.0" encoding="UTF-8" ?><amc:view xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amc="http://xmlns.oracle.com/jdev/amc"> <amc:form id="form0"> <amc:menuControl refId="menu0"/> <amc:panelGroupLayout id="panelGroupLayout1" width="100%"> <amc:panelGroupLayout id="panelGroupLayout2" layout="horizontal" width="100%"> <amc:image id="image1" source="logo_sm.png"/> <amc:outputText value="Home" id="outputText1" verticalAlign="center" fontSize="20" fontWeight="bold" foregroundColor="#ff0000"/> </amc:panelGroupLayout> <amc:commandLink text="#{MyBean.property1}" id="commandLink1" actionListener="#{MyBean.doFoo}" foregroundColor="#0000ff" action="patientlist"/> </amc:panelGroupLayout> </amc:form> <amc:menu type="main" id="menu0"> <amc:menuGroup id="menuGroup1"> <amc:commandMenuItem id="commandMenuItem1" action="exit" label="Exit" index="1" weight="0"/> </amc:menuGroup> </amc:menu></amc:view>
