You do not really have to buy those books.
Only if you want to tweak your installation.
But if you want to deploy things and tweak them it is good to know something about the plumbing and developing good ejb applications is not simple.
Thanks for you reply...
Tweak the installation? Well, are the docs that explain how to deploy and configure the server included?
I am not sure what you mean by "tweak"? I've deployed apps on Tomcat, Weblogic and it's never just the installation. You need to know what to change to get your DataSource setup. You need to know where to go to, say get your security setup, get it to use digested passwords with encryption algorithms...
I need to know if I would spending $100 on mostly finding out things that are beyond the regular basics, like "how the server works on the hood", or on how to set up the server, configure it and know where to go to change things that every day J2EE development and deployment needs. Where is the hot deploy area? How do I setup connection pooling? How do I set up JMS? How do I setup global JNDI? and so on...
So, I need to find out if the documentation will give me a very good "how-tos" manual.
Do not know anymore actually where i got the information from.
But most questions and answers i think can be found in this forum. There are sample apps in the documentation and you can search for most of you questions in those samples.
Furthermore it takes time. I actually only know jboss pretty well (For what i am using it).
And the hot deploy
But there are some class loading issues.
And now about the tweaking is how to configure EJB loading stratigies keeping things in the cash enso enso
And you could see the documentation also as a license fee for jboss $100 is not that much for an app server
