Problem:

• Product name: VisiBroker for Java
• Product Version: 7.0
• Product Component: runtime
• Platform/OS Version: All, JBuilder 2006

The easiest way to run a VisiBroker 7.0 Java program outside any IDE environment is to use the vbj launcher. The vbj launcher predefines the parameters needed by VisiBroker to run the specified program as a CORBA server or CORBA client. To know the parameters set by vbj launcher, run "vbj -VBJdebug" at the command line:

D:\\Project2008\\bank_portable\\src>vbj -VBJdebug
Loaded Java VM Library C:\\Borland\\VisiBroker7\\jdk\\jdk1.5.0\\jre\\bin\\client\\jvm.dll

 option[13] = "-Djava.class.path=C:\\Borland\\VisiBroker7\\lib\\patches;C:\\Borland\\VisiBroker7\\lib\\vbejb.jar;...

Alternatively, instead of using the vbj launcher, you may invoke the java executable to run the program directly, and that, is the main intention of this article.

Resolution:

•  

To run a VisiBroker Java program using the Java executable directly, certain properties need to be specified as JVM parameters. The number of parameters and the libraries required depend on the program to be run.
Using the bank_naming example (included in VisiBroker 7 distribution) for illustration:
For the client program, vbjorb.jar or vbjclientorb.jar and log4j.jar will have to be included in the classpath and the following JVM properties specified:

-Dorg.omg.CORBA.ORBClass=com.inprise.vbroker.orb.ORB 
-Dorg.omg.CORBA.ORBSingletonClass=com.inprise.vbroker.orb.ORBSingleton 
-Dvbroker.agent.enableLocator=false -DORBInitRef=NameService=corbaloc::143.186.141.142:33333/NameService

For the server program, vbjorb.jar, log4j.jar, lm.jar and sanct6.jar will have to be included in its classpath and the following JVM properties specified:

-Dorg.omg.CORBA.ORBClass=com.inprise.vbroker.orb.ORB 
-Dorg.omg.CORBA.ORBSingletonClass=com.inprise.vbroker.orb.ORBSingleton 
-Dborland.enterprise.licenseDir=C:\\Borland\\VisiBroker7\\var 
-Dborland.enterprise.licenseDefaultDir=C:\\Borland\\VisiBroker7\\license 
-Dvbroker.orb.admDir=C:\\Borland\\VisiBroker7\\var\\vbroker\\adm 
-Dvbroker.agent.enableLocator=false -DORBInitRef=NameService=corbaloc::143.186.141.142:33333/NameService

To turn on debug logging, add two more JVM properties:

-Dvbroker.log.enable=true -Dvbroker.log.logLevel=7

Using the JBuilder 2006

The JBuilder 2006 can be set up to run a VisiBroker application through the Java executable. Similar to the independent Java program, you need to specify the path of the VisiBroker libraries, as well as the properties to be passed as JVM parameters.

 

The libraries are specified through Project Properties -> Required Libraries tab.
The JVM properties are specified through Runtime Configurations -> VM parameters field.

Attached to this article is an archive file which embeds screenshots of the JBuilder 2006 configuration for the libraries as well as runtime JVM properties. Also included are VisiBroker logs and a network packet capture that can be viewed using Wireshark. You could download from here.
