> Does anyone know where I can download Arjuna Transaction Service 4.0?
It's not open source and Arjuna pretty much no longer market it to new customers. In short, you are probably out of luck unless you are an existing Arjuna customer.
> If not does anyone know if TIBCO BusinessWorks can be used with JBoss Transactions 4.2.3?
What are you trying to achieve exactly?
Ah, I believed it was open source.
Generally TIBCO BusinessWorks can be configured to use Arjuna Transaction Service 4.0 as a transaction manager. I was just wondering if JBoss Transactions 4.2.3 is compatable as well. I shall chase this up with TIBCO support.
The product source was transferred to JBoss, but various changes were made before the first open source release under the JBoss brand, so you can't get the exact ArjunaTS 4.0 code easily. TIBCO have an OEM agreement to ship it as embedded binary, they are not using the (L)GPL license. TIBCO support are definitely the people you need to talk to in the first instance, we don't even have a copy of BusinessWorks to hand.
OK - thanks for your help
