Hot to refer a factory method from other seam action class

visumagic Dec 17, 2008 7:12 PM

I'm still novice in seam. I would like to know
1)how we can refer a scoped seam factory from a other seam action.
2)How to refer expression language which returns a value ..

point (2) may fix point 1 , because we can refer a factory using expression language easily

I found Contexts.lookupInStatefulContexts
hopefully it should work,this is going to search all the contexts it would be better if the function name is changed to serchInAllContexts , ..

But it's not able to refer psydo-componets (factory) ..
how we can refer to factories directly ..

I think you are looking for org.jboss.seam.Component.getInstance().

There are various flavors:

Component.getInstance(Class clazz, boolean create) Component.getInstance(Class, ScopeType scope) Component.getInstance(String name)

Regarding expression evaluation I would look at org.jboss.seam.core.Expressions.

Hope this helps.

I found a good method to evaluate expressions. using which we can access all scoped components.

Object value = Expressions.instance().createValueExpression("#{parameters.requestParamaters}").getValue();
