> Key: IBATIS-424
> URL: https://issues.apache.org/jira/browse/IBATIS-424
> Project: iBatis for Java
> Issue Type: Task
> Components: DAO, SQL Maps
> Affects Versions: 2.3.0
> Environment: Windows XP, WSAD 5.1.2, Oracle 10.1.0.4.0 database and 10.1.0.2.0 Oracle-JDBC driver.
> Reporter: Sumeet Gupta
>
> I am using a simple iBatis call to a stored procedure, which takes two integers as IN parameters and a REF CURSOR as an OUT parameter.
> The REF CURSOR contains a single column, which is of type TIMESTAMP.
> The SQL map configuration file is like:-
> <?xml version="1.0" encoding="UTF-8" ?>
> <!DOCTYPE sqlMapConfig
> PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
> "C:/iBATIS/lib/sql-map-config-2.dtd">
> <sqlMapConfig>
> <transactionManager type="JDBC" commitRequired="false">
> <dataSource type="SIMPLE">
> <property name="JDBC.Driver" value="oracle.jdbc.driver.OracleDriver"/>
> <property name="JDBC.ConnectionURL" value="MY_URL"/>
> <property name="JDBC.Username" value="MY_USER_ID"/>
> <property name="JDBC.Password" value="MY_PASSWORD"/>
> </dataSource>
> </transactionManager>
> <sqlMap resource="com/fmr/fims/ibatis/data/MyMap.xml"/>
> </sqlMapConfig>
> The SQL Map file is something like-
> <?xml version="1.0" encoding="UTF-8" ?>
> <!DOCTYPE sqlMap
> PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
> "C:/iBATIS/lib/sql-map-2.dtd">
> <sqlMap namespace="MyMap">
>
> <resultMap id="ResultData" class="com.fmr.fims.ibatis.domain.TestResult">
> <result property="time" column="TIMESTAMP" />

> <procedure id="SP_TEST" parameterMap="TEST_PARAM_MAP" resultMap="ResultData">
> { call FUTURES_ACTIONS_PKG.SP_TEST(?,?,?) }
> </procedure>
> </sqlMap>
> The following is my Java code's snippet:-
> String resource = "com/fmr/fims/ibatis/data/SqlMapConfig.xml";
> Reader reader = Resources.getResourceAsReader(resource);
> System.out.println("Successfully read the resource file");
> SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);
> System.out.println("Before calling the query");
> Map paramMap = new HashMap(3);
> paramMap.put("MAX", new Integer(26));
> paramMap.put("MIN", new Integer(24));
> paramMap.put("RESULT","");
> sqlMap.queryForObject("SP_TEST", paramMap);
> Map resultMap = (Map) paramMap.get("RESULT");
> The Oracle stored proc simply returns a cursor, which contains a specific column values (using SELECT statement), given a range (MAX and MIN as parameters).
> This is the error that I am getting:-

> Is this an environment issue?
> Please help. I read that this may be caused due to a stale connection. However, ibatis is handling the connection related stuff for me. What do i need to do next?
