Default Transaction Manager

Hi,

I  am using IBATIS w/ Spring and wanted to know what would be the default
transaction manager  if there is one not defined in sql-map-config.xml.

All I have is 

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">

<sqlMapConfig>

	<settings
		cacheModelsEnabled="true"
		enhancementEnabled="true"
		lazyLoadingEnabled="true"
		maxRequests="10"
		maxSessions="1"
		maxTransactions="5"
		useStatementNamespaces="false"
	/>

	<typeAlias alias="abc" type="com.abc.bbc"/>

    <sqlMap resource="/WEB-INF/abc.xml"/>

</sqlMapConfig>

Would container manager transaction come into affect if nothing is defined
in sql-map-config.xml ?

Thanks for the response Chris.

I have another question for you. If I have a file where sqlmapconfig.xml I
have mentioned it as 	<transactionManager type="JDBC" >
		<dataSource type="JNDI">
			<property name="DataSource" value="jdbc/abcd"/>
		</dataSource>
	</transactionManager>
Would the connection parameters set in sqlmapconfig.xml would come into
affect ? I tried changing the parameters to default values in setting
section but it caused a major problems with connections. The application was
not able to handle those many connections

The setting was as follows

<settings
		cacheModelsEnabled="false"
		enhancementEnabled="true"
		lazyLoadingEnabled="true"
		errorTracingEnabled="true"
		useStatementNamespaces="false"
                          maxRequests="512"
		maxSessions="128"
		maxTransactions="32"
		
	/>
Which connection parameters would come into affect? The one that is
mentioned in sqlmapconfig.xml or the parameters associated with JNDI
configurations ?

As I remember, if you're using the Spring SqlMapClientTemplate, iBATIS will
assume you're using an EXTERNAL transaction manager.  So whatever you have
defined (or don't have defined in your case) in the sql-map-config.xml will
be ignored.
