Hi devs,
I am a tuscany user in Apache PhotArk and I have an unexpected issue with my
two services and I tried to resolve this many times, but couldn't figure out
a way.
I have implemented two working tuscany SCA components named,
FacebookFriendFinder
and FaceRecognitionService.
I use the service FaceRecognitionService inside the service
FacebookFriendFinder.
Following is a kind of a p*seudo code* code to explain my situation.
*In FacebookFriendFinder Impl class *
Photo processFBFriends() {
...
...
Photo p = FaceRecognitionService.recognize("file"); // call the recognize
method in the service, FaceRecognitionService.
*--- program does not return to this line, it terminates*
}
*In FaceRecognitionService impl class*
public Photo recognize(String s) {
...
...
Photo p = someAPI.recognize();
*// system.out(p) -- When I do a system.print to the Photo p before the
return statement, it prints the expected "p".*
return p;
}
I am confused with this. Though "p" prints and is available just before the
return statement in the class FaceRecognitionService it doesn't pass to its
parent method any how. *When I changed the return types to String from
Photo, it works fine and return the string. *
So is there a problem in interacting among two tuscany SCA service
components when dealing with custom objects like (org.face4j.Photo) other
than java native ones ?
It will be great if I can get some idea to resolve this issue.
Thanks
