SunOne ejbRemove not called

[Trevor Nelson]

Hello
I have a stateful session bean that needs to timeout after ten minutes. I have specified this in the sun-ejb-jar.xml as below, but the bean is not timing out as the session stays active after the timeout period.

<bean-cache>
<removal-timeout-in-seconds>600</removal-timeout-in-seconds>
</bean-cache>

Can anyone suggest how this xml should look and whether any other code or xml in the deployment descriptor is required.

The version of SunOne being used is 7.

Many thanks
