Question

我正在研究MAC OS X - 10.7.5，WSO2 ESB 4.6.0和数据服务功能 - 4.0.5

Java java版“1.6.0_37” Java（TM）SE运行时环境（版本1.6.0_37-b06-434-11M3909） Java HotSpot（TM）64位服务器VM（版本20.12-b01-434，混合模式）

我正在尝试使用ref cursor执行存储过程。

这是我的DS

<data name="RZM">
   <config id="RZS_Data">
      <property name="driverClassName">oracle.jdbc.driver.OracleDriver</property>
      <property name="url">XXXX</property>
      <property name="username">XXXX</property>
      <property name="password">XXXX</property>
      <property name="defaultTransactionIsolation">TRANSACTION_READ_COMMITTED</property>
   </config>
   <query id="TEST" useConfig="RZS_Data">
      <sql>call RT_PROC_GET_VERSION(:in_app_id,:in_version_id,?,?,?)</sql>
      <result element="Results" rowName="Result">
         <element column="app_url" name="app_url" optional="true" xsdType="string"/>
         <element column="out_message" name="OutMessage" optional="true" xsdType="string"/>
         <element column="out_err_message" name="out_err_message" optional="true" xsdType="string"/>
      </result>
      <param name="in_app_id" ordinal="1" sqlType="INTEGER" type="INOUT"/>
      <param name="in_version_id" ordinal="2" sqlType="STRING" type="INOUT"/>
      <param name="compare_from_id" ordinal="3" paramType="ARRAY" sqlType="ORACLE_REF_CURSOR" type="OUT"/>
      <param name="out_message" ordinal="4" sqlType="STRING" type="OUT"/>
      <param name="out_err_message" ordinal="5" sqlType="STRING" type="OUT"/>
   </query>
   <operation name="TOP">
      <call-query href="TEST">
         <with-param name="in_app_id" query-param="in_app_id"/>
         <with-param name="in_version_id" query-param="in_version_id"/>
      </call-query>
   </operation>
</data>

我一直在跟踪错误

我不确定为什么会收到此错误。我正在尝试使用“TryIt”服务执行DS。输入XML如下：

<body>
   <p:TOP xmlns:p="http://ws.wso2.org/dataservice">
      <!--Exactly 1 occurrence-->
      <p:in_app_id>1296</p:in_app_id>
      <!--Exactly 1 occurrence-->
      <p:in_version_id>2.2</p:in_version_id>
   </p:TOP>
</body>

存储过程定义从以下

开始

     create or replace procedure RT_PROC_GET_VERSION (in_app_id                in number,
                                                    in_version_id           in varchar2,
                                                    out_version_detail      out sys_refcursor,
                                                    out_message             out varchar2,
                                                    out_err_message         out varchar2)
    is
    begin
            open out_version_detail for
            select
                    app_url, switch_board_url, version
.
.

end RT_PROC_GET_VERSION;

你能帮帮忙吗？谢谢作者Abhijit

Answer 1

我也一直在和它斗争我花了一些时间调试代码，并认为MessageContext中的请求原因是'null'。因此，它导致Axis2传输配置影响了它。事实上，WSO2 ESB 4.6.0带有默认的传递http传输，它不会创建消息体，这就是为什么传递给服务的任何东西都不起作用的原因。因此，为了使其工作，您需要在org.wso2.carbon.core.transports.http.HttpTransportListener中重新启用其他http传输（例如查找和取消注释repository/conf/axis2/axis2.xml）这应该可以解决您禁用路径的问题。也许有办法在不同的端口上并排配置传输（稍后的任务）

一句话，通常你应该分别保留ESB和DSS作为解决不同的任务并需要特定的配置。

Answer 2

阿济斯，

同时使用“命名参数”和“序数”（带数字的参数排序）会导致参数提取和赋值中的一些问题。我建议您统一使用“命名参数”选项或“序数”（两者中只有一个）来分配所有输入参数映射。这样可以解决问题。

希望这有帮助！

Answer 3

尝试此调用RT_PROC_GET_VERSION（？，？，？，？，？）

在输入映射选项列表中，所有in和out参数都带有序号。序数将基于问号。有一点是上面查询中出现的问号应该与你存储的proc一样。在存储过程之后，如果有任何数据将它们列在参数

中

例如：如果您的结果集带有id和地址，那么在输出映射中列出这两个。注意：输入映射名称应与存储过程中的相同。

带有数据服务器插件的ESB 4.6.0 - 无法使用REF_CURSOR执行存储过程
