PL/SQL stored procedures are called from within JDBC programs by means of the prepareCall() method of the Connection object created. A call to this method takes variable bind parameters as input parameters as well as output variables and creates an object instance of the CallableStatement class.
The following line of code illustrates this:
CallableStatement stproc_stmt = conn.prepareCall("{call procname(?,?,?)}");
Here conn is an instance of the Connection class.
