How set transaction timeout at method level?

[granby]

I am probably missing something obvious but; how do I set transaction timeout at method level? I found a descriptor for doing this but I didn?t manage to make it work. I tried this on the stateless example:

meta-inf/jboss.xml:

<enterprise-beans>

<ejb-name>org.jboss.tutorial.stateless.bean.CalculatorBean</ejb-name>

<method-attributes>

<method-name>add</method-name>
<transaction-timeout>1</transaction-timeout>


<method-name>subtract</method-name>
<transaction-timeout>20</transaction-timeout>

</method-attributes>

</enterprise-beans>

Since I am also unsure about how to connect these settings to the Calculator bean, I wasn?t very hopeful. My guess was the ejb-name attribute but what should I put there? Or is there an annotation that I have completely missed?

So actually this is two questions in one:

How do I add additional attributes via a deployment descriptor to an EJB3 session bean?

Is there an annotation for setting transaction timeout for a method in a stateless session bean?

please log a feature request on JIRA if you want these features. They all sound good.

Ok. I posted a feature request: http://jira.jboss.com/jira/browse/EJBTHREE-298

There is only a few methods in the application (not the tutorial exampel) for which I need a longer timeout. I know that you can set a query timeout but this is not a query. Can I accomplish this in any practical way?

Jboss 4.2.1GA

I have a 'setup' which takes ages (>20 mins) to generate the data I need. I tried the @TransactionTimeout method annotation but can't find it in the jars.

Is this available, and where is it please? If not, is there another approach I can use ... it's only for a few, known, long-lasting methods - not for general use!

Thanks

It's in jboss-annotations-ejb3.jar. Make sure that your method starts the transaction or else the transaction timeout has no effect.
