I'm sure this has been asked many times before, and there is an easy solution, but I want to be able to pass data between two or more beans. I've looked around online quite a bit, but I'm unable to find something that explains this well enough for me to understand. I've got JSF 1.2.
In the simplest case, suppose I have two classes as follows:
public class MyBeana {
private String mynamea;
public Mybeana() {
// Whatever initialization
}
public void setMynamea(String mynamea) {
this.mynamea = mynamea;
}
public String getMynamea() {
return mynamea;
}
// Other methods that may act on the methods above or in MyBeanb.
}
public class MyBeanb {
private String mynameb;
public Mybeanb() {
// Whatever initialization
}
public void setMynameb(String mynameb) {
this.mynameb = mynameb;
}
public String getMynameb() {
return mynameb;
}
// Other methods that may act on the methods above or in MyBeana
}
I've tried playing around with FacesContext, but I'm unable to get it to work.
Another idea is to use dependency injection in the faces-config.xml file with something like:
<managed-bean>
<managed-bean-name>beana</managed-bean-name>
<managed-bean-class>com.csharp.MyBeana</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>beanb</property-name>
<value>#{beanb}</value>
</managed-property>
</managed-bean>
<managed-bean>
<managed-bean-name>beanb</managed-bean-name>
<managed-bean-class>com.csharp.MyBeanb</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
but I don't know what syntax to use. Basically, I could have pages with tags such as:
<h:inputText value="#{beana.mynamea}">
<h:inputText value="#{beanb.mynameb}">
plus many others, and want to be able to access the methods of one bean from the other.
The link
http://wiki.apache.org/myfaces/AccessingOneManagedBeanFromAnother gives some useful information, but it's not very clear, and a simple worked example would be a great help.
I would most appreciate some help with this.
