Hello Friend,
I'm new to Tuscany and SCA. I have gone through the available
samples. I'm not able to get the following scenario working.
Please reply if there is any limitation, or if my approach is wrong.
My requirement is to use tuscany 1.4 & spring inside a java web
application. I did the following.
composite file
--------------------------
has a service entry, and it is promoted to a component
(implementation.spring).
The component points to the spring application context.
spring application context file
------------------------------------------------
has an sca:service entry, and it is targeting a spring bean.
domain configuration
------------------------------
the sca-contributions.xml is put in the META-INF folder of the web
archive. It indicates the deployable composite.
my requirement
-----------------------
invoke a method of the spring bean from a jsp page.
what i did
--------------
added an sca reference in the jsp page
it should invoke the service of the composite. That in turn passes the
call to component inside the composite.
The service exposed by the component (which is a sca spring
implementation) gets called.
And it is transferred to the spring bean.
Result / Problem
-------------------------
I'm not able to locate the spring context file. Still the file is there in
the same folder as the composite.
The error stack is listed below this email.
Question
--------------
I got the spring sample applications running in tuscany standalone
environment.
Any limitations for tuscany 1.4 & spring inside a java ee server like
tomcat?
Regards,
Rupesh
