Re: InjectObject w/o abstract

[Gerald Schöffel]

Hi nevez,

you could define your Factory as a service-point in hivemodule.xml, 
letting hivemind instantiate it for you.

Then you define your class as a 'normal' one, using simple java properties:

private IHandler handler ;
public IHandler getHandler() { return this.handler ; }
public void setHandler(IHandler handler) { this.handler = handler ; } ....

In hivemodule.xml you can set those properties:

<service-point id="manoInterceptoriusFactory" 
interface="ServiceInterceptorFactory">
        <invoke-factory>
                <construct class="...package.manoInterceptoriusFactory">
    			<set-object property="handler value="service:handleris"/> 
(depends on the source of handleris)
                </construct>
        </invoke-factory>
</service-point>

I hope this is right - I am very new to Tapestry/Hivemind - so I hope 
this handwritten code is ok.

Bye,
Gerald

&#125;

and it doesnt work: 

org.apache.hivemind.ApplicationRuntimeException: Unable to construct service 
tapestry.page.PagePool: Unable to construct service test1.manoInterceptorius: 
Unable to instantiate instance of class test1.manoInterceptoriusFactory: 
java.lang.InstantiationException 
[file:/C:/workspace/tomcatProjects/test1/exploded/WEB-INF/classes/META-INF/hivemodule.xml,
 line 17, column 61]

i think its because of abstract class.
so do you have any ideas on getting the object w/o using abstract class?
