Those which designate the execution environment (Java hypothetical machine) of programming language Java of the Sun Microsystems corporation as plug in type of the Web browser. By the fact that it makes shape of plug in, always the Java hypothetical machine of up-to-date version can be utilized. In the past was called “Java Activator”.

Java was adopted for many browsers, but as for version of the Java hypothetical machine of execution environment being various with the version of the browser, making the Java applet which used new technology, as for many people the circumstance that occurred it cannot play back that.

Then, those which it tries to be able to call the Java hypothetical machine of appropriate version making use of the mechanism of plug in which can call the cord/code from Internet dynamically, by offering execution environment with plug in, are Java Plug-in. Because it becomes plug in type, it is not necessary to prepare on user side, can utilize up-to-date Java environment with anytime.

As for [saburetsuto] because it is described with Java language, there is no OS of specification, and times when it depends on the hardware it is possible to make work with all Web servers who mount [saburetsuto] API.

Unlike the other server side program of CGI and the like, when one time it is called, in order to be permanently stationed that way in memory, high speed processing is possible. In addition, because it is possible, to handle the data lastingly, it is possible also to share information between the group of users.

At the beginning it was offered as the functional one of Java Web of the Sun Microsystems corporation Server, but specification it becomes independent as Java Servlet API, presently execution environment of [saburetsuto] is prepared in for the various Web servers.

It is the cord/code for execution which the compiler of Java forms. It has the feature that in one kind of intermediate code, it does not depend on the environment of specification. After the Java byte cord/code being converted by the native cord/code by the interpreter inside the Java hypothetical machine, it is executed.
