How to access page A.jsp's variable inside page B.jsp's bean constructor
I've been stuck with the following problem for a while now:
I have two pages called A.jsp and B.jsp backed by A-Bean.java and B-Bean.java.
On page A.jsp i have a text box where the user enters a code. Depending on this code, page B.jsp creates a drop down list. The values for this drop down list are created via an array list in the bean's constructor. How can I access page A's variable inside B's constructor ?
I'd appreciate any help. Thanks in advance
Why not using a managed property?
<managed-bean>
<managed-bean-name>beanA</managed-bean-name>
...
</managed-bean>
<managed-bean>
<managed-bean-name>beanB</managed-bean-name>
...
<managed-property>
<property-name>referredBean</property-name>
<value>#{beanA}</value>
</managed-property>
</managed-bean>
public class BeanB {
private BeanA referredBean; // remember the setter
public String secondPageAction() {
// get what ever properties from BeanA (referredBean),
// initialised the list
return "next";
}
...
}
The markup above assumes that the list is not initialised in BeanB constructor, but in secondPageAction instead.

Thanks pringi and lamekisser, you guyz solved the problem
i set the bean property in the config file and used the following java code to access it:
Config:
<managed-bean>
<managed-bean-name>Person</managed-bean-name>
<managed-bean-class>demo.PersonBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>userName</property-name>
<property-class>java.lang.String</property-class>
<value/>
</managed-property>
<managed-bean>
JavaCode
FacesContext fc = FacesContext.getCurrentInstance();
String userName = (String)fc.getApplication().createValueBinding("#{Person.userName}").getValue(fc);
