One major feature of the Java language is the ability to "write once, run anywhere." You can develop and test
applications on a workstation using JORB Lite with out tying up NSK system resources. This capability means
that you can generate JORB Lite clients and servers and move their generated .class bytecode files to the
NonStop Kernel for execution in a NonStop CORBA environment. You can also move the client or server
.class files and allow JORB Lite applications to interoperate with NonStop CORBA applications. Note that
the Java Swing and AWT packages are not supported on NonStop systems.
To use JORB Lite as a development and test environment, follow these general steps (an example follows later
in this section):
Design and code your application as you normally would.●
Execute the JORB Lite env.bat file to point to the location of the Java Virtual Machine (JVM) on your
workstation. Ensure that the PATH environment setting includes the JVM and that the CLASSPATH
includes the location of the Java JVM classes, jorblite.jar, and nsdidl.jar files on your
workstation. The default location is c:\jorblite\etc\env.bat.
●
Create and run a make.bat file to generate your Java files and build the client and server applications.●
Set up any necessary client and server profile entities in the lite.dbm file. The default location is
c:\jorblite\lib\lite.dbm.
●
Start a second Command Prompt window, and run the env.bat file.●
Run your client and server programs.●
Test and verify your application in the JORB Lite environment.●
Once you have developed your application on your workstation, you can move the generated .class files
(binary mode) using a file-transfer program such as FTP to a directory on Open System Services. Then:
Use the cfgmgt tool to configure the NonStop CORBA server application profile. See Application
Profiles: Configuring and Managing an Application for more information.
●
Start two OSS windows and execute the $NSD_ROOT/etc/env.sh script on the NSK system.●
Because the .class bytecode files built using JORB Lite now reside on the NonStop Kernel under Open
