FUJITSU Software BS2000 JENV

The Java™-based development and runtime environment for portable and secure Web applications.

Current versions: V8.1 and V9.0


The Internet programming language Java™ and its corresponding runtime environment are having a significant impact on the whole of enterprise computing. The Java concept (“write once, run anywhere”) allows applications to be run via networks of heterogeneous computer systems - embracing the most varied platforms and operating systems.

FUJITSU Software BS2000 JENV (BS2000 Environment for Java™) enables BS2000 systems to run all Java programs created on any platform. Similarly, Java applications and Java applets developed for BS2000 can also run on other platforms. Programs created with JENV can be run on any platforms that have a JAVA-compatible runtime environment.
