Store procedure call to fetch data in JDBC sender adapter

Question

Hi guys,
I have to fetch data from a Oracle server through JDBC adpater.
the partner has in place some store procedure that have to be used with this purpose.
But al the time I try to call a store procedure I got error that variables are not binded.
I fill up the query sql statement field with following text
call <store procedure name> (v1 OUT VARCHAR2, v2 in varchar2)
Does anyone know the syntax to access such store procedure within jdbc adapter?
As far as I know the jdbc call the store procedure with Callable statement but the paremeters need to be linked to datatype,but here I do not see such possibility.

HI
A stored procedure is a subroutine available to applications accessing a relational database system. Stored procedures (sometimes called a sproc or SP) are actually stored in the database data dictionary.
Typical uses for stored procedures include data validation (integrated into the database) or access control mechanisms. Furthermore, stored procedures are used to consolidate and centralize logic that was originally implemented in applications. Large or complex processing that might require the execution of several SQL statements is moved into stored procedures and all applications call the procedures only.
Stored procedures are similar to user-defined functions (UDFs). The major difference is that UDFs can be used like any other expression within SQL statements, whereas stored procedures must be invoked using the CALL statement
Stored procedures can return result sets, i.e. the results of a SELECT statement. Such result sets can be processed using cursors by other stored procedures by associating a result set locator, or by applications. Stored procedures may also contain declared variables for processing data and cursors that allow it to loop through multiple rows in a table. The standard Structured Query Language provides IF, WHILE, LOOP, REPEAT, CASE statements, and more. Stored procedures can receive variables, return results or modify variables and return them, depending on how and where the variable is declared.

One of the usage is to prevent the query to directly write to the database
