DbAdapter invocation issue

Question

Hello everyone,
I have a stored procedure in a SqlServer 2012 database, as follows:
CREATE PROCEDURE [dbo].[SP_GET_PERSONS]
@Id varchar(15), @FirstName varchar(30), @LastName varchar(30)
WITH EXEC AS CALLER
AS
BEGIN
     Declare @SQL VarChar(MAX)
  CREATE TABLE #records
       Id int,
       FstName varchar(50),
       LstName varchar(50)
  insert into #records
  select Id, First_Name, Last_Name
  from Persons
  where First_Name like '%'+@FirstName+'%'
    or  Last_Name like '%'+@LastName+'%'
    or  Id like '%'+@Id+'%'
  declare @query nvarchar(MAX)
  set @query = 'select Id, FstName, LstName from #records'
  execute (@query)
END
GOWhen I execute this SP in a SQL client (such as squirrel), it returns rows successfuly.
From this, I have created a JCA dbadapter in order to use it in OSB. Then, I generated a business service based in the JCA file.
So far so good!
When I test the business service with the same input tested in the sql client, I don't get any error neither any result. I simply get this:
<soap-env:Envelope      xmlns="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
<soap-env:Body>
<OutputParameters      xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/sp/my_sp_namespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
</soap-env:Body>
</soap-env:Envelope>However, if I change the stored procedure to simply perform the select statement instead of the execute with the temporary table inside, both the execution in the sql client and the invocation to the business service returns the expected result!
<soap-env:Envelope      xmlns="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
<soap-env:Body>
<OutputParameters      xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/sp/my_sp_namespace" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RowSet>
<Row>
<Column      name="Id" sqltype="int">1</Column>
<Column      name="First_Name" sqltype="varchar">James</Column>
<Column      name="Last_Name" sqltype="varchar">Monty Python</Column>
</Row>
</RowSet>
</OutputParameters>
</soap-env:Body>
</soap-env:Envelope>I have tested this issue with both Oracle's driver (weblogic.jdbc.sqlserver.SQLServerDriver) and MS driver (com.microsoft.sqlserver.jdbc.SQLServerDriver)
Does anybody know why this happen? Any tips?
Kind regards and thanks in advance,

Hi Jose,
the DbAdapter's db.jca file contains a property MappingsMetaDataURL, which points to an Oracle TopLink file ending in or-mappings.xml.
The first entry in this xml file is (for 11.1.1.2.0):
<toplink:object-persistence version="Oracle TopLink - 11g Release 1 (11.1.1.2.0) (Build 091016)" xmlns:opm="http://xmlns.oracle.com/ias/xsds/opm" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:toplink="http://xmlns.oracle.com/ias/xsds/toplink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
Starting in 11.1.1.3.0, whenever you create an or-mappings.xml, we now use the EclipseLink schema, which is the open source version of TopLink. So the head element looks like this:
<object-persistence xmlns="http://www.eclipse.org/eclipselink/xsds/persistence" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:eclipselink="http://www.eclipse.org/eclipselink/xsds/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="Eclipse Persistence Services - 2.1.2.v20101104-r8475">
11.1.1.3.0 can read either schema. However 11.1.1.2.0 can only read the first one. Maybe what happened is you are trying to run on 11.1.1.2.0 a process that was at least partially modeled on 11.1.1.3.0.
Failing that maybe your *or_mappings.xml file is corrupt somehow, and you should run through the DbAdapter wizard in edit mode to hit finish and regenerate it, or try doing so.  You may need to recreate it and redeploy.  Also make sure you are not using an 11.1.1.3.0 JDev with 11.1.1.2.0.
Thanks
