Insight into New Lutris Training

The introduction of EAS 4 provided an opportunity for Lutris Educational Services to create a whole new course designed to help developers quickly leverage the new features of EAS. That course extends the existing curriculum to meet the needs of a wide range of developers.

The Fundamentals course is a 3-day class that provides participants with a complete, hands on experience, that includes using XMLC, Kelp, InstandDB, the Web Admin Console, Lutris Management Console (LMC) and appwizard. After completing this hands on segment of the course participants then proceed to develop a complete Web Application that meets the needs of a hypothetical client. This segment uses the most common techniques needed to develop the majority of web sites today. These include the use of JNDI, JDBC, Servlets, Session objects, the most common uses of XMLC for HTML DOM manipulation, and deployment of the application once the development is complete.

The 2-day EAS Wireless course extends the application created in the Fundamentals course by using XMLC to target WML and VoiceXML clients. This process also provides participants with the information they need to target any tag based markup language that has a corresponding DTD. It also covers the topics related to targeting devices other than the standard HTML browser in general.

The new 2-day course EAS Advanced Techniques provides participants with hands on practice with the most commonly used features of the new EAS 4 product. The course extends the sample application developed in the earlier courses by adding EJBs, SOAP access to the application, creating an EAS Service, and developing a highly scalable, highly available cluster using the DynaCluster component that is new with EAS 4.

Creating, deploying and administering an EJB in the EAS framework is covered in every detail and participants do each and every step of this process. This involves the use of the Kelp tools, LMC, Web Admin Console, and the EAS server itself. It also involves creation of the WAR, JAR, and EAR files for this project as well as the accompanying XML files.

Creating a SOAP based interface that can provide a client with data from existing sources within an application or organization is fundamental to the future of Web Services. Participants deploy an industry standard SOAP service (APACHE SOAP) within the EAS framework and connect the Entity Bean deployed in the earlier section to the SOAP service via an RPC server they create. They also create a SOAP client that can use the data exposed through the SOAP interface.

Next participants create an EAS Service. This is a major new feature of EAS that provides developers with the ability to easily wrap legacy code and deploy it within the EAS. It also provides easy versioning and administration of that code within the new framework.

Finally participants deploy the application and build a cluster of machines running the application. This includes using DynaLink, a web server of choice, and DynaCluster as well as the LMC. Participants create a cluster that provides session replication and session level fail over to provides user with uninterrupted access during scheduled or unscheduled failure of individual servers or groups of servers.
