The purpose of this post is to set up Oracle WebLogic Server environment consisting of two managed servers running on separate machines within one domain. On a such prepared environment will be installed Java EE application suite. An installed Oracle WebLogic Server and appropriate JDK is here an assumption. The guide is focused on providing necessary steps to build up managed servers arrangement. This post is an extension to the “Local and remote EJB performance comparison” parts  and provides more technical aspects.
Collecting and analyzing results
In this post are executed EJB performance tests on the technical infrastructure designed in PART I. The aim of these tests is to perform local and remote calls between EJB components and collect information about time spent on these calls. In the beginning is given a brief introduction to a business interface then is elaborated a test scenario. The last part is a result presentation and an attempt to define final conclusion.
Technical infrastructure development
It is an obvious fact that local EJB calls are more efficient than remote. The aim here is to observe the difference between these calls in terms of time and resources consumption and finally provide observation results. In this post is given an overview and an explanation of a technical infrastructure with a goal to measure both local and remote EJB calls. The infrastructure consists of Java EE application suites and two managed servers running on Oracle WebLogic application server.
EJB components differ from Spring beans on the technical background whereas their concept is quite similar. The technical diversity might be an issue when composing dependencies between these two bean types. The purpose of this post it to give an idea to design solutions based on a mutual EJB and Spring beans interoperability. There are taken into account two main concerns: accessing EJB components from Spring beans and accessing Spring beans from EJB components. The post introduces technical aspects referring to a simple enterprise application implementing beans cooperation.
