Application Resources via EJB's - Need some help plz

Title: Message

Hi,

 

I'm trying to make Struts to use EJB's AND files to get the Resource propperties.

For example, I'll have standard (static) App-resources files under (for instance) WEB-INF/classes/acme/Application.properties  and I'll have an EJB under (for example [jndiName]) "acme/Application".  Struts will first try and find the property in the bean, if unsuccessful, or the bean could not be found, or any other EJB problem, it will read the property from the file. 

 

This will allow for more dynamic properties that can be set during runtime.  If I do some "dirty bean" checking now and again I can load changed properties from the bean when required.

 

Now for my problem:

I cannot get an instance of the bean.

As you'll see from my code, I'm not all to good with dynamicaly accessing classes.

I'm trying this:

-------------------

Context ctx = new InitialContext(env);

Object obj = ctx.lookup( "acme/Application" );

...

Class bcHome = Class.forName("app.resources.ApplicationHome");

...

Object boHome;

boHome = PortableRemoteObject.narrow(obj, bcHome); //<-LINE 35

...

 

And get the following:

------------------------------

java.lang.InstantiationException: app.resources.Application

      at java.lang.Class.newInstance0(Unknown Source)

      at java.lang.Class.newInstance(Unknown Source)

      at CallResourcesEjb.main(CallResourcesEjb.java:35)

 

Please see the attached file for a full code listing.

 

Thanks.
