I'd like to seek for more information on how to configure proper JNDI data source setting for using JDBC transaction manager in iBatis DAO. I encounter this error when my DAO JDBC implementation execute a stored procedure:
[12/13/04 18:16:12:188 CST] 40362530 SystemErr R com.sybase.jdbc2.jdbc.SybSQLException: Stored procedure 'aidcconfig..po_uam_get_user' may be run only in unchained transaction mode. The 'SET CHAINED OFF' command will cause the current session to use unchained transaction mode.
We're using iBatis 2.0.8.470, WASD 5.1 and Sybase ASE 12.5. In WebSphere 5.0 (embedded in my WASD 5.1), I have defined a normal Sybase data source with JNDI name using Sybase JConnect 5.5 JDBC Driver. In web.xml, I have defined a resource reference to point to the Websphere JNDI entry. The store procecedure po_uam_get_user has just some simple select statements without "begin tran" or "commit" command.
But when I comment out "connection.setAutoCommit(false)" statement in the com.ibatis.dao.engine.transaction.jdbc.JdbcDaoTransaction.java, the error disappears and my java program can select correct data from Sybase.
Does it related to my data source or web.xml setting? Or related to whether I use XA driver or not?
Provided that above can be solved, I would like to know further that how can I achieve two-phase commit capability via iBatis DAO with the following dao.xml and statements. I have no idea of what type of configuration I have to make on my application server.
<context>
<transactionManager type="JDBC">
<property name="DataSource" value="JNDI"/>
<property name="DBJndiContext" value="java:comp/env/jdbc/policy"/>
</transactionManager>
<dao interface="PolicyServiceDaoIF" implementation="PolicyServiceDaoJdbc"/>
<dao interface="AuditServiceDaoIF" implementation="AuditServiceDaoJdbc"/>
</context>
private DaoManager daoManager = DaoConfig.getDaomanager();
policyDao = (PolicyServiceDaoIF) daoManager.getDao(PolicyServiceDaoIF.class);
auditDao = (AuditServiceDaoIF) daoManager.getDao(AuditServiceDaoIF.class);
try {
daoManager.startTransaction();
policyDao.addPolicy(policy);
auditDao.log("addPolicy - " + policy.getPolicyId());
daoManager.commitTransaction();
} finally {
daoManager.endTransaction();
}
Looking forward to your reply.
