JBoss embedded and Seam questions?

[statelessbean]

Hi,
I just read docs of jboss embedded and there is topic

Defining a datasource conf/embedded-jboss-beans.xml

Do I need to configure this file for my Seam 2.0.0GA app and Tomcat 6.0?

(My app so far works fine and I nothing configured in this file.)

2. How can I manage transaction timeout in my seam and jboss embedded app?

I try to google and google and found this, but for weblogic:

<transaction-descriptor>
 <trans-timeout-seconds>60</trans-timeout-seconds> </transaction-descriptor>

for ejb-jar.xml
but I'm not sure that this will work.
Can anyone help me to find answer for this issue?

I think I found solution for second question.
In /conf/jboss-service.xml we need set

 <mbean code="com.arjuna.ats.jbossatx.jta.TransactionManagerService"
 name="jboss:service=TransactionManager">
 <attribute name="TransactionTimeout">XXX</attribute>
 </mbean>

Where XXX is time of transaction (in seconds), and is globally set for server.
