A first look at Rnext (continued)
- Java Server Pages: The Sun Java standard for dynamic page creation is a standard part of the IDE (Interactive Development Environment) as well;
- Style Sheets: Cascaded style sheets are now stored within the Domino Designer client; they're edited/created via a non-Domino tool (like, for example, Dreamweaver), and the results are stored in the Domino database container;
- Data Connections: Connections to enterprise data sources are now easily created/maintained within a Domino database;
- Database Resources: The About, Using, database icon, and database script elements have been moved to their own category called Database Resources.
Lotus continues its love affair with Java
Take a quick look at the new and improved Domino environment, and a trend is recognized: Lotus continues its love affair with Java. In addition to the servlet and JSP (Java Server Pages) support, Rnext includes an updated version of the JDK (Java Development Kit) with 1.3. Many Java enthusiasts will be disappointed by the lack of J2EE (Java 2 Enterprise Edition) support. There's no support for EJB (Enterprise JavaBeans). Rnext is not a J2EE server.
Lotus' answer to such a request is to point you towards WebSphere. WebSphere is a full-blown J2EE platform that tightly integrates with Domino. Let's take a quick peak at servlet and JSP development.
Figure E shows the servlet development environment included with Rnext.

Here's the servlet development environment included with Rnext. Roll over picture for a larger image.
For now, Rnext servlets utilize only the doGet method with the doPost method not implemented.
A new servlet is created in the example above. Servlets can only use Java with Imported Java and Java entered into the environment. The Java 1.3 IDE included in the servlet development environment creates the basic framework for a basic servlet. The doGet method and the creation of Domino objects is included as well, with these lines:
NotesThread.sinitThread();
session = NotesFactory.createSession();

Figure F shows the creation of a new Java Server Page within the Domino Designer.

The basic framework for a JSP is set up by Domino. A JSP comment is included to signal where your JSP code is to be placed.
JavaScript
Another excellent development with Rnext is the ability to create JavaScript Script Libraries. I did a backflip with this discovery. [We've been trying to get video from Tony, but, to our ongoing disappointment, he's thus far been unwilling to share the film of his acrobatics. -DG].
The reason for my excitement is that working with JavaScript in R5 (and R4.6) was somewhat cumbersome. Sharing JavaScript within an application presented many problems requiring many ingenious workarounds (otherwise known as "hacks"). Rnext makes these efforts needless; JavaScript functions are entered into a Script Library and shared accordingly. Figure G presents a sample JavaScript library.
