FYI I found the cause of this: There is an XSL transform in the ibatis-sqlmap-1-x.jar upgrade that does an on the fly conversion when using the old format config files. When it encounters useGlobalTransactions in the settings it assumes the user is using User Managed Transactions and tries to get the JNDI names from the settings as well. However, when useGlobalTransactions is set in the old it does not necessarily mean they are using user managed transactions, by default it means they are using external transactions. The XSL incorrectly translates the file to JTA with JNDI name "". It should translate to transaction type EXTERNAL.

Apparently what it is trying to do is an on the fly conversion from the old format to the new format (found by tracing through iBatis source code). However, we don't have anything transaction related in our config file other than a settings option to specify using global transactions. We let the EJB container handle the demarcation of our transactions. When iBatis does the conversion, it seems to default to using JTA transactions, tries to lookup the UserTransaction with JNDI name "" and then throws the ClassCastException. Any ideas on how to fix this without having to do a manual conversion of the file (although I will do that if that's the only way, but someone might want to add this to the upgrade guide). Here's the part of our config file that is causing problems: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sql-map-config PUBLIC "-//iBATIS.com//DTD SQL Map Config 1.0//EN" "http://www.ibatis.com/dtd/sql-map-config.dtd";> <sql-map-config> <settings useGlobalTransactions="true" cacheModelsEnabled="true" /> <!--settings useBeansMetaClasses="true"/ Investigate, suppose to be big performance improvement--> <datasource name="snmDataSource" factory-class="com.ibatis.db.sqlmap.datasource.JndiDataSourceFactory" default="true" > <property name="DBFullJndiContext" value="java:/dsname" /> </datasource> .. Rest of stuff here ... </sql-map-config>
