It has been corrected, please try and download the sources again. To answer your question: sharing the transaction between a jdbcTemplate and TopLinkDAO should work fine. In my example I don't have any transactions in my unittest configuration. The AbstractTransactionalDataSourceSpringContextTests takes care of the transactions in the testcases. That gives you a hook to test the behaviour of the DAO's when certain situations occur. For example the unexpected ending of a transaction...

One remark: I couldn't find the calls to setComplete and endTransaction that you refer to in the article in the source code attached. I was triggered to look for these methods, because in our project we do not use this technique. With Spring managed transactions you can make the JdbcTemplate and the Dao's share the same transaction, this works for Hibernate, does it for TopLink? See Spring's <a href="http://springframework.org/docs/api/org/springframework/jdbc/datasource/TransactionAwareDataSourceProxy.html" rel="nofollow">TransactionAwareDataSourceProxy</a> and <a href="http://springframework.org/docs/api/org/springframework/orm/hibernate3/LocalSessionFactoryBean.html#setUseTransactionAwareDataSource(boolean)" rel="nofollow">setUseTransactionAwareDataSource</a> <a href="http://springframework.org/docs/api/org/springframework/orm/ibatis/SqlMapClientFactoryBean.html#setUseTransactionAwareDataSource(boolean)" rel="nofollow">methods</a>.
