Inject spring bean into managed backing bean (jsf)

lee

I want to use one of my spring bean classes in a jsf backing bean.

For example I have a spring bean called: configuration.
So I've put this in the jsf bean:

<managed-property>
           <property-name>configuration</property-name>
            <value>#{configuration}</value>
        </managed-property>

But when the code tries to use the configuration class it throws a null pointer (because the configuration object isn't there.

Any idea how to get around this? I really don't want to have to duplicate all sorts of code in the jsf backing bean.

Thanks
Lee

Do you have, in your Java class (represented by the JSF bean) written the "configuration property" and the dedicated the setter method :


public Configuration configuration;

public void setConfiguration(Configuration configuration) {
         this.configuration = configuration;
}

Hi JayJay,

Thanks for your response. Yes I do have a dedicated setter method. However a null object always gets injected to the jsf bean.

I was, however, shown a workaround by Brian R from Ixxus:

You need to use a static member of the class

public class JSFObject {
   private static Configuration config;

   public void setConfig(Configuration config) {
     JSFObject.config = config;
   }

Then create both a spring bean that injects the required object (in this case: Configuration). Then all instances of the jsf bean will share the same configuration object.
