需要帮助从Java JDBC代码调用存储过程

Question

我在Oracle DB中有一个过程。它的设计如下。

CREATE OR REPLACE PROCEDURE SUMMARY_PAGE(P_NEWID IN number, SHORT_NAME OUT VARCHAR2)
IS
CURSOR C1 IS
        SELECT d.short_name "Program Name",
       d.number "PD# - P/S:",
FROM  des_styles d,ent_workflowstates e1,
WHERE style_id=P_NEWID;
BEGIN
FOR I IN C1
LOOP
EXIT WHEN C1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(I."Program Name"|| ' '||I."PD# - P/S:");
 END LOOP;
end;
/

我有JDBC CODE，如下所示

Connection dbConnection = ConnectionManager.getDBConnection();
String sql="{ call SUMMARY_PAGE(?,?) }";  
CallableStatement callStatement = dbConnection.prepareCall(sql);
callStatement.setInt(1, 31146);
callStatement.registerOutParameter(2, Types.VARCHAR);
boolean g = callStatement.execute();

事实是，执行函数返回false。请告诉我如何从上面的代码中获取“Short_Desc”结果。

提前致谢。
