WebLogic: Past, Present and Future by Michel Schildmeijer

clip_image002Oracle WebLogic is for quite some years the key platform for Enterprise Java Applications. Through its long history of development and building, it has become the most complete, mature and stable application server platform, ready to serve old technology but more than ready for the coming new technologies which are following up each other in a speed that no one would ever thought of. This article will give you an overview of how WebLogic started, how it became the platform as it now is, and what to expect in the future. Enjoy reading!

WebLogic: Ancient History

If you browse on the internet and enter “weblogic” (Myself, I prefer, as a WebLogic geek, always to type its original Camel Case written name WebLogic) you will find some Wikipedia pages with a timeline and history about the versions that has passed, up to the latest versions ( if the Wikipedia pages are updated).

But how did it all begin? I was eager to hear it in person from one of the founders of WebLogic back in 1995, before the BEA era, Laurie Pitman.

Four young people, Carl Resnikoff, Paul Ambrose, Bob Pasker, and Laurie Pitman, became friends and colleagues about the time of the first release of Java in 1995. They all had a Master Degree in various areas of expertise, and they had come together kind of serendipitously, interested in building some web tools exclusively in Java for the emerging Internet web application market. They found many things to like about each other, some overlap in our interests, but also a lot of well-placed differences which made a partnership particularly interesting. They made it formal in January 1996 by incorporating. Read the complete article here.

Encrypt & decrypt your way into WebLogic SSL by Michel Schildmeijer

clip_image002The title of this blog may seem a bit cryptic…. In this article I’d like explain some basics of the the SSL implementation in WebLogic. This blog is meant for people who are not familiar with SSL, especially in combination with WebLogic.

In my experience, SSL is usually a bit of a black box for many junior and medior administrators who work with middleware, so I will try to clarify some of it in special relation to WebLogic. To understand this, there are also some generic parts to discuss. SSL is a technique to secure a point-to-point socket connection, in  the so-called transport layer which will be secured.  It provides secure connections for interfaces or (web) applications to connect and authenticate each other’s identity, and  by encrypting the data traffic between those interfaces or application back ends.

Authentication allows a server, and sometimes optionally, a client to verify the identity of the application on the other end of a network connection. SSL uses the public key encryption technology for this. With public key encryption, a public key and a private key can be generated for a back-end server. This key is used to encrypt data before sending. After the client has recieved the key, it can decrypt it using that same key. So data encrypted with the public key can only be decrypted using the corresponding private key and vice versa.

It’s is like sending a locked safe with some transportcompany along with a note which contains the unlock combination. The public key is embedded in a digital certificate with additional information about the initiator of the key. This information may consist of name, street address, email address, company information and some geographic information. A private key and a digital certificate provide an identity for the server. The data embedded in a digital certificate is verified by a certificate authority and digitally signed with the certificate authority’s digital certificate.

Well-known certificate authorities include Verisign and The trusted certificate authority (CA) certificate establishes trust for a certificate. Below is an overview of a “happy SSL flow”: Read the complete article here.

WebLogic 12c experience Michel Schildmeijer

Michel Schildmeijer Technical Author at Packt Publishing and Oracle Fusion Middleware Solutions Architect at AMIS Services published several WebLogic 12c articles:

WebLogic 12c questions and answers

I collected some Q&A for you during the WebLogic 12c launch so here they are:


To read the full article please visit Michael Schildmeijers’s blog

WebLogic 12c released!

New or enhanced WebLogic 12c features

  • JAVA EE 6 support all kinds of JEE6 specifications are implemented like :
    • JSF 2.0,Java Servlets 3.0 JPA 2.0 and EJB 3.1.
    • Managed Beans 1.0
  • WebLogic 12c also supports supports Java SE 7 (and Java SE 6).
    • Java language optimizations and Internationalization
    • Client and server support
    • SSL/TLS 1.2 in JSSE to support JAVA Socket Transport security
    • Converged Java VM:JRockit and HotSpot are  incorporated with the best features from both.The JVM convergence will be a multi-year process, which was confirmed during my presence at Oracle’s Publisher Seminar 2011 during OOW

I won’t discuss the full list in this blog because there’s more about WebLogic than only (although very important of course!) the JAVA EE 6 specifications.

  • Support for IDE’s. WebLogic already supported JDeveloper, but will come out with the later on. Also suported are Eclipse and NetBeans 7.1 IDE. As said, the JDeveloper and IntelliJIdea IDE will be supported in a later timeframe.
  • New enhanced WebLogic Maven Plug-in See the various new options below in this scheme

As you can see, you can even build a simple domain or control it out of Maven!

  • WebLogic 12c provide upgrades from
    • iAS with automated tooling
    • WebLogic 11g
    • GlassFish redeployment – With a built in GlassFish descriptor recognition for Re-Deployment to WebLogic Server
    • JBoss and webSphere with migration services
