Read-only method calls on Session Bean

[bobbyjboss]

I have been unable to establish the sematics associated with a method level read-only = true attribute on a session bean. (Contained within jboss.xml)

ie


<ejb-name>XXXXXXXXXX</ejb-name>
<method-attributes>

<method-name>get*</method-name>
<read-only>true</read-only>

</method-attributes>


Are objects used with this method call locked ?

My understanding of the same attribute on entity beans is that they are not locked for the entire transaction but merely for the duration of the method call.

Do I have this right ?

thank you

I do not think you can have read-only for session bean's methods.

Look at the @ejb.transaction (0..1) tag for the bean methods. You can use type="Supports" or "NotSupported".

Supports: If you are not sure if this should participate in the transaction.
NotSupported: If you are sure that you do not want to rollback based upon exceptions from this method.

thanks,

The dtd for the jboss.xml http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd
supports the the idea of the read-only methods on session beans and entity beans.

This is a jboss entension and not part of the ejb spec.
