NullPointer Exception thrown in GeneralStatement.executeQueryWithCallback when
using Log4j
------------------------------------------------------------------------------------------
Key: IBATIS-152
URL: http://issues.apache.org/jira/browse/IBATIS-152
Project: iBatis for Java
Type: Bug
Components: SQL Maps
Versions: 2.1.1
Environment: Windows XP, Java 1.3
Reporter: David Winterbottom
Hi,
I am trying to follow the supplied test for IBATIS-53 (Oracle ref cursors).
I have found that running the supplied test (number 6) with log4j-1.2.9.jar on
the classpath causes a NullPointerException.
The stack trace and output is:
DEBUG [main] - Created connection 3235124.
DEBUG [main] - {conn-100000} Connection
DEBUG [main] - {pstm-100001} PreparedStatement: { ? = call
mis_extract.mgr_case_temp.FindCases }
DEBUG [main] - {pstm-100001} Parameters: []
DEBUG [main] - {pstm-100001} Types: []
DEBUG [main] - {rset-100002} ResultSet
DEBUG [main] - Returned connection 3235124 to pool.
com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in com/kinnect/mis/datamodel/sql/CaseToExtract.xml.
--- The error occurred while applying a parameter map.
--- Check the output.
--- Check the output parameters (retrieval of output parameters failed).
--- Cause: java.lang.NullPointerException

Is there a known problem with log4j with IBatis ?
Is this a problem for RefCursors only ?
