upgrading from old version defaults to wrong TransactionManager
----------------------------------------------------------------
Key: IBATIS-20
URL: http://nagoya.apache.org/jira/browse/IBATIS-20
Project: iBatis for Java
Type: Bug
Environment: jboss 3.2.1, iBatis 2.0.8 (upgraded from iBatis 1.2.9)
Reporter: alex mccarrier
We are using EJB to demarcate transactions. Old iBatis sql config file
contained this:
<settings useGlobalTransactions="true"
cacheModelsEnabled="true" />
<datasource name="snmDataSource"
factory-class="com.ibatis.db.sqlmap.datasource.JndiDataSourceFactory"
default="true" >
<property name="DBFullJndiContext"
value="java:/DataSource" />
</datasource>
Which configured iBatis to use external global transaction management, which
from the documentation I understand this to be the default unless I specify to
use Managed Global Transactions by including settings attribute called
"userTransactionJndiName" (iBatis 1.2.9 manual, pp 39-40).
When iBatis 2.0.8 tries to do the conversion, it defaults to Managed Global
Transactions, then throws a ClassCastException because it can't find a
UserTransaction object at jndi name "" (because there is none specified).
