[jira] Commented: (TUSCANY-875) Databinding not able to transform
when a java component is invoking a web service
[ http://issues.apache.org/jira/browse/TUSCANY-875?page=comments#action_12443592 ]
Venkatakrishnan commented on TUSCANY-875:
-----------------------------------------
Hi Raymond,
I was also trying to see if the calculator sample can be exposed as a webservice. I did that successfully. Then I tried to invoke this from a standalone sca client. Here are my observations: -
- When I invoke the divide service that has two arguments, I encountered the same exception as Jojo. Also I figured out that there is some incompatibility with respect to Input2Input transformation with source type (java) containing two arguments and the target type (webservice) containing only one argument (prob. since it is wrapped style). All this is on the client.
- then I tried calling another service with just one argument. This time around the call crossed client but encountered exceptions on the server side. On ther server side the SimpleType2JavaTransformer ends up passing a null simpleType to the SimpleTypeMapperExtension. There seems to be some problem in extracting the type info.
