All you need to do is to inject the bean whose method you want to use in the other bean. In ADF there is an easy way to achieve this. You should have a file called adfc-config.xml
inside your WEB-INF folder. If you open it's source, you'll notice that each bean is described inside the <managed-bean>
tag. It will be something like:
<managed-bean id="__2">
<managed-bean-name>bean1</managed-bean-name>
<managed-bean-class>com.domain.Bean1</managed-bean-class>
<managed-bean-scope>view</managed-bean-scope>
</managed-bean>
for each bean. You have to insert a <managed-property>
tag inside with a reference of the bean you want to inject, just like this:
<managed-bean id="__2">
<managed-bean-name>bean1</managed-bean-name>
<managed-bean-class>com.domain.Bean1</managed-bean-class>
<managed-bean-scope>view</managed-bean-scope>
<managed-property>
<property-name>bean2</property-name>
<value>#{Bean2}</value>
</managed-property>
</managed-bean>
Also, inside the Bean1 class you have to create an instance variable of Bean2, and then you can use it to get its current state.
