In JBoss 3.0+, it's a <config-property> named "TransactionIsolation" you
need to add to your data source deployment. Here's an example from our
mysql-service.xml:
<depends optional-attribute-name="ManagedConnectionFactoryName">
<!--embedded mbean-->
<mbean code="org.jboss.resource.connectionmanager.RARDeployment"
name="jboss.jca:service=LocalTxDS,name=MySqlDS">
<attribute name="JndiName">MySqlDS</attribute>
<attribute name="ManagedConnectionFactoryProperties">
<properties>
<config-property name="ConnectionURL"
type="java.lang.String">jdbc:mysql://localhost:3306/jbossdb</config-prop
erty>
<config-property name="DriverClass"
type="java.lang.String">com.mysql.jdbc.Driver</config-property>
<!--set these only if you want only default logins, not
through JAAS -->
<config-property name="UserName"
type="java.lang.String">root</config-property>
<config-property name="Password"
type="java.lang.String">password</config-property>
<config-property name="TransactionIsolation"
type="java.lang.String">TRANSACTION_SERIALIZABLE</config-property>
</properties>
</attribute>
<!--Below here are advanced properties -->
<!--hack-->
<depends
optional-attribute-name="OldRarDeployment">jboss.jca:service=RARDeployme
nt,name=JBoss LocalTransaction JDBC Wrapper</depends>
</mbean>
</depends>

Subject: Re: [Jboss-user] Serializable Transactions?
It's always a good idea to tell us what jboss version you are using. I
think you can set transacction isolation for all jboss 3++ versions in
the
datasource configuration file. As I recall you can use a string == the
constant name. If it's not in an example file look in the ra.xml for
one
of the wrappers.
I think it is also possible to set this in 2.4, but don't remember the
details.
