Integration

hello everybody,

I try to interact with adapters from my Spring component. I actually try to start my query and to receive the result in my Spring Component.

I've already search for documentation about api to communicate with it or documentation about the classes created during the db adapter creation... But .. no result..

So I'm trying to do it my self but I encounter some problems when I'm trying to call the query on the dbAdapter and trying to "play" with the classes created by the db adapter.

Could anyone say me HOW we can interact with adapters from Spring component (in the class bean)?

Also, how can I access to the variables? Is there an equivalent of "getVariableData" and "setVariableData" that I can use in the Spring Component? with which jar and/or import?

I copy/paste what I've already done.
-----
So My Composite contains a Web Service "getStatusByCC" which is linked to a Mediator. The Mediator calls the Spring Component "SprinCallDB" and the Spring Component is linked to a database adapter called "getCreditValidation". The transformation in the mediator component is correct (I test it without the call to the db and it works fine)

First, there is the classes created and added to my project by the db adapter :

So, the line which is the cause of the error is the following :
resultSet = dbRequest.getCreditValidationSelect(selectCCNb);
in the SpringCCServiceImpl.java class

And there is the error I obtain :

+weblogic.sca.api.ScaException: java.lang.RuntimeException: BINDING.JCA-12563 Exception occured when binding was invoked.

Any idea is welcome! :)

If you have great urls to communicate with adapters and variables from spring component, don't hesitate to post it!

Thanks in advance,
