About the section Configuring the EJB Client Address.
First of all, the sentence There are two ways to configure the EJB client address: is misleading. These are not two different ways which you can choose from, but rather two different scenarios depending on your use case (whether you're invoking beans from a standalone client, or from a container) - you can't choose which one you will use.

But, do we need to include such details anyway? What I'm missing is a more general description what the feature is about - the details will be available after clicking on the hyperlink to the development guide.
What does "configuring EJB client address" mean? I think a general description would suffice here - it should describe the purpose of the feature, which is binding the EJB client's socket to a particular source address/port, and that the target EJB bean can then read the source address/port of the remote client who invoked it.
