Hello All
I have some questions concerning @Context annotation
1/ What kind of informations are stored in such an object ?
2/ when is it instanciated ?
3/ Is there an exemple showing how to use @Context in an SCA
client ?
Thanks
Fahim
Hi Fahim
Sorry about that, must have missed this main in my reader. The
@Context annotation is used to inject either a component context or a
reference context into a component instance. Which one depends on the
type of the filed that is annotated, e.g.
@Context
protected ComponentContext myContext;
@Context
protected RequestContext myContext;
You can see the interfaces for these objects in the SCA API here
(http://svn.apache.org/repos/asf/tuscany/java/sca/modules/sca-api/src/main/java/org/osoa/sca/)
The component context gives you access to the information about the
component itself such as the properties and references that the
component defined. You can, for example, retrieve a reference proxy
from the component context and then use it to call the referenced service.
The request context gives you access to the information about the
current request, for example, information about any active callback
endpoints.
Our itests use the @Context annotation in various places. For example,
http://svn.apache.org/repos/asf/tuscany/java/sca/itest/callablereferences/src/main/java/org/apache/tuscany/sca/itest/callableref/AComponentImpl.java
Hope this helps

Hi Simon
I will try to use this annotation and the corresponding APIs in some
application to get services and references.
Thanks a lot for you answers.
