The WASD Java environment was first implemented in December 1997 and there has been no further development since... so there may still be a few wrinkles `:^(` Developed using the first-release JDK1.1 beta kit for OpenVMS Alpha V7.1 Verified working (and modified slightly) with the final release JDK 1.1.6 in September 1998. Verified as still working with the JDK 1.1.8-3 update in June 2000.

|  | This directory provides some demonstration Java scripts. These are here only to provide examples on approaching scripting using this environment ... and of course to provide some skeletal code for use in real Java scripts. Of course the demos. will only work if Java is installed on the server system! The class that makes CGI support relatively easy is CGIplus.java (javadoc). Note that due to the way classes are specified by the WASD server Java class names invoked as main()s must be all lower case.

For setup requirements check the Scripting chapter in the Technical Overview.

Compaq's JDK documentation can usually be found in SYS$COMMON:[SYSHLP.JAVA]

Class files (essentially the executables) are located in the common HT_ROOT:[JAVA] directory (because, of course, they are architecture independent :^)

Note that all these scripts are executed using the CGIplus path, however some behave as standard CGI scripts, exiting after responding to the request, while the others persist, responding to multiple requests. The CGIplus path is always necessary however as all use the CGIplus variable data stream to retrieve the CGI variables.
