Accessing SCA standalone reference from another EAR

Hi,<br />
 I have a BPEL module with standalone reference. I have another EAR with a web
project, which has a jsp. How do i access the standalone reference from the
jsp.<br />
The projects have individual EAR's.<br />
<p />

Hi,



Your question is a good question. I don't know how to do this. My workaround is
using other bindings (JMS or Webservice),export your component and creating a
simple java client.



Regards,

Code in one EAR can't see an SCA stand-alone reference definition in another 
EAR (module).

If your central EAR (web app / jsps) is non-WPS then it can't use the SCA 
programming model. As already suggested it must use some other protocol (eg 
WebService client with SOAP/HTTP, or send a message via JMS) to invoke the 
remote service (with the WPS modules exporting a service with the 
corresponding binding).

I haven't tried this myself but I believe the alternative is to make your 
central EAR into a WPS Module. The SCA assembly for that module could just 
be a stand-alone reference component (with one or more references) and one 
or more imports. The JSP can use the prescribed APIs (BOFactory, 
ServiceManager etc) with a stand-alone reference to invoke the SCA services 
in other modules through the imports and their bindings as if the JSP is an 
SCA component. That way you still maintain the separation between the 
central EAR and the various services.
