Oracle 建立过程Update_projectAdjust(vWoNO in varchar2,adjustDay in number)
java程序中建立了Connection con如何调用上面的过程

CallableStatement cstmt = null;
        try
        {
            String sql = "{call P_ADD_DOC(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)}";
            cstmt = conn.prepareCall(sql);

            cstmt.registerOutParameter(7,Types.INTEGER);
            cstmt.registerOutParameter(8,Types.INTEGER);
            cstmt.registerOutParameter(9,Types.DATE);
            cstmt.registerOutParameter(10,Types.INTEGER);
            cstmt.registerOutParameter(11,Types.DATE);
            cstmt.registerOutParameter(12,Types.INTEGER);
            cstmt.registerOutParameter(13,Types.INTEGER);
            cstmt.registerOutParameter(14,Types.INTEGER);
            cstmt.registerOutParameter(15,Types.INTEGER);
            cstmt.registerOutParameter(16,Types.INTEGER);
            cstmt.setString(1,title);
            cstmt.setInt(2,father.getID());
            cstmt.setInt(3,creator.getUserID());
            cstmt.setInt(4,CommonDoc.SINGLEDOC);
            cstmt.setString(5,firstVersion);
            cstmt.setString(6,"00.00.01");

            cstmt.execute();
            this.ID = cstmt.getInt(7);
            this.type = CommonDoc.SINGLEDOC;
            this.createTime = cstmt.getDate(9);
            this.modifier = cstmt.getInt(10);
            this.modifyTime = cstmt.getDate(11);
            this.ownerID = cstmt.getInt(12);
            this.ownerPermission = cstmt.getInt(13);
            this.ownerGroupID = cstmt.getInt(14);
            this.groupPermission = cstmt.getInt(15);
            this.publicAccess = cstmt.getInt(16);
        }
        catch(SQLException e)
        {
            throw new MyException(e,"数据库连接错误！");
        }
        finally
        {
            conn.close(cstmt);
        }

callableStatement cstmt = conn.prepareCall("{?=call client_no (?,?)}");                    
cstmt .registerOutParameter(1,java.sql.Types.Types.VARCHAR);
                    cstmt .setString(2,"sdfa");
                    cstmt .setInt(3,2);
                    cstmt .executeUpdate();
                    result = cstmt .getString(1);

使用：callableStatement对象
