Re: ASO and hivemind.xml
Others might chime in because I'm no expert on this, but this what I believe to be true... - The module id and version can be arbitrary. However, to avoid name clashes you can use the id as a qualifier, eg. @InjectState(jumpstart: serviceLocator) So the id forms a namespace. Why would you get name clashes? Because you can have more than one hivemodule.xml file in your classpath and HiveMind will pick up all of them - in addition to its own hivemind.xml. - The package name allows you to abbreviate your class names in the rest of the module, which I didn't do, so I wasted that feature. Can someone else confirm all of this? Cheers, Geoff On 20/07/2006, at 9:33 PM, Blackwings wrote: Thanks a lot, but I have a question again: To what, the id in the module tag, refer?

Re: ASO and hivemind.xml
The situation is :
I create class that extends ApplicationServlet and I specify it as the
tapestry main servlet in web.xml. In this class I call a class that
initialise some application objects such as list of element common to
everybody from the database.
My class also set a bean member and implement the get/set method.
I also specified this class as an ASO as you told me to do Geoff and I put
the inject tag in my Home.page.
At the loading of the application, my application object is loaded
normally and contains all the list.
When I call the Home.page, the inject seems to work and the pageBeginRender
is called normally. I call getMyASO() I declared abstract, but when I try to
get the application object it is null!!
I think Tapestry recreate an instance of MyASO instead of directly get the
first loaded :

Re: ASO and hivemind.xml
Howard, thanks for the advice. I have to use JDK1.4 so I cannot use annotations. My real problem is to understand how I can instanciate an object at the context load, in the ApplicationServlet via inheritance and to make this object available to my pages. As I already explained, getGlobal is Deprecated so I have to use the ASO and the inject tag. My question is to understand how ;o) I was able to instanciate my object (appSettings in the code I wrote in my previous post), I was able to setup hivemodule.xml to create an instance of an object but i was not able to inject the right instance of the object. Can you help me on this part please?
