Why should I use the Java interface?
The WebSphere MQ classes for Java programming interface makes the many benefits of Java available to you as a developer of WebSphere MQ applications:
- The Java programming language is easy to use.
There is no need for header files, pointers, structures, unions, and operator overloading. Programs written in Java are easier to develop and debug than their C and C++ equivalents.
- Java is object-oriented.
The object-oriented features of Java are comparable to those of C++, but there is no multiple inheritance. Instead, Java uses the concept of an interface.
- Java is inherently distributed.
The Java class libraries contain a library of routines for coping with TCP/IP protocols like HTTP and FTP. Java programs can access URLs as easily as accessing a file system.
- Java is robust.
Java puts a lot of emphasis on early checking for possible problems, dynamic (runtime) checking, and the elimination of situations that are error prone. Java uses a concept of references that eliminates the possibility of overwriting memory and corrupting data.
- Java is secure.
Java is intended to be run in networked or distributed environments, and a lot of emphasis has been placed on security. Java programs cannot overrun their runtime stack and cannot corrupt memory outside their process space. When Java programs are downloaded from the Internet, they cannot even read or write local files.
- Java programs are portable.
There are no implementation-dependent aspects of the Java specification. The Java compiler generates an architecture-neutral object file format. The compiled code is executable on many processors, as long as the Java runtime system is present.
If you write your application using WebSphere MQ classes for Java, users can download the Java byte codes (called applets) for your program from the Internet. Users can then run these applets on their own machines. This means that users with access to your Web server can load and run your application with no prior installation needed on their machines.
When an update to the program is required, you update the copy on the Web server. The next time that users access the applet, they automatically receive the latest version. This can significantly reduce the costs involved in installing and updating traditional client applications where a large number of desktops are involved.
If you place your applet on a Web server that is accessible outside the corporate firewall, anyone on the Internet can download and use your application. This means that you can get messages into your WebSphere MQ system from anywhere on the Internet. This opens the door to building a whole new set of Internet accessible service, support, and electronic commerce applications.
