Foil 14 New Java Frameworks for Advanced Web Services (I)

From Multidisciplinary Applications MAPINT97 Workshop -- 16-18 June 97. *
Full HTML Index
A large number of new Java APIs for advanced Web Services are emerging from JavaSoft and partners. Many current problems such as with the NPS WebDIS networking will be soon solved in a more robust, stable and elegant fashion by the new high-level APIs.
Java APIs are organized in Java Frameworks. Current list of frameworks include:
  • Java Applet Framework - base JDK1.0.2 packages such as java.lang, java.util, java.io, java.net and java.awt.
  • Java Enterprise Framework - JavaIDL (CORBA API), RMI (Remote Method Invocation a.k.a Java-to-Java custom (non-CORBA) ORB), JDBC (Java Database Connectivity), Java Serialization, Java Web Server.

Java Media Framework - Java2D (with Adobe), animation (with Macromedia), audio/video (with Intel), Java3D (with SGI), JSDA (Java Shared Data API).
All APIs listed are either already operational within JDK1.1, or still in works (spec only or alpha or beta release) but with the final release dates in 1997.

These are too many frameworks and probably several are rather controversial as there is no agreed model of the use of Web in Computing

2) The Computing Services Framework which we give a little more detail on.
