Web dynpro dc compoent controller method call from Java dc class file

[Former Member]

Hi All,

Is it possible to call a wd java component controller method from a java dc class file?

I have declared wd java dc as used dc in java dc.Any poiters for the same would be really helpful.

Thanks in Advance.

Hi,

short answer: No.

1. using WD references outside of WD DCs is unsupported and will at least show a warning when you try to deploy. Correct usage of runtime dependencies is not predictable.

2. WebDynpro Controllers have a lifecycle that is controlled by the Framework. Even if you manage to initialize a Controller via "new" and use a method, the Controller will never have all the state-information it contains when started regualary. (think of mapped context, context attributes in general, code called in wdInit ...) I would suppose it is possible to implement a runnable low-profile example that still works, but as soon as you try to use "higher" concepts of WD (which would be the only reason to use a WD Component Controller at all), you will definitely fail.

3. Think of it as calling EJBs Session Beans via "new", but more complex.

hope that helps
