Platforms

This release of the IBM(R) Java(TM) ORB (Object Request Broker) runs on SDKs for HP-UX and Solaris that have been adapted by IBM, and the SDK 32-bit SDK for Windows(R).

The exact platforms supported by this release of the IBM Java ORB are:

For HP-UX, this release covers both 32- and 64-bit, Itanium(R) and PA-RISC processors.

This version of the IBM Java ORB is not supported on the IBM 32-bit SDK for Windows, Java Standard Edition, Version 5.0.

Installation and setup

The IBM Java ORB is included with IBM-supplied SDKs. To install the IBM Java ORB on a non-IBM SDK, extract the orb package in the SDK directory. Ensure that the IBM Java ORB is included before any other ORB implementation in the PATH environment variable.

To install the IBM Java ORB on Solaris and HP Hybrid Java SDKs:

  1. Set up the following environment variables:
    1. Set JAVA_HOME environment variable to point to the location where your SDK is installed (for example, /opt/ibm/IBMJava2-50/).
    2. In your PATH environment variable, ensure that <JAVA_HOME>/ibm_bin precedes <JAVA_HOME>/bin.

To install the IBM Java ORB on Windows:

  1. Unzip the orb50-<DATE>.zip file in the directory where your SDK is installed (for example, C:\Program Files\IBM\Java50\).
  2. Set up the following environment variables:
    1. Set JAVA_HOME environment variable to point to the location where your SDK is installed.
    2. In your PATH environment variable, ensure that <JAVA_HOME>\ibm_bin precedes <JAVA_HOME>\bin.

Using the IBM ORB development tools

The scripts ibm_bin\rmic.bat and ibm_bin\idlj.bat (on HP and Solaris, the files do not have the .bat extension) allow you to use the IBM version of idlj and the IBM back-end generators for the rmic -iiop and -idl options.

These scripts do not work on Windows 95 and Windows 98.

If you are invoking idlj from your application's code, you must invoke the main class com.ibm.idl.toJavaPortable.Compile.

If you want to invoke rmic from your application's code, ensure that lib\ibmtools.jar is on the application's classpath (not on the rmic classpath). The main class is sun.rmi.rmic.Main.

To check whether you are using the IBM Java ORB, use the -version option, which is valid only if used with -iiop or -idl: 

rmic -iiop -version

If the output is:

-version is an invalid option or argument

you are not using the IBM version. You should see a message similar to:

IBM Compiler for RMI over IIOP build orb50-yyyymmdd

Using the IBM ORB naming service

The scripts ibm_bin\tnameserv.bat and ibm_bin\orbd.bat (HP and Solaris, the files do not have the .bat extension) allow you to use the IBM version of tnameserv and the reference implementation of orbd.

Restriction: These scripts do not work on Windows 95 and Windows 98.

If you are invoking tnameserv from your application's code, you must invoke the main class com.ibm.CosNaming.TransientNameServer.

Release contents

The IBM Java ORB includes tools, data files, and jar files.

The files included are:

For further information about the IBM ORB extension, refer to the information supplied with the IBM v5.0 SDKs.

Coexistence considerations

The IBM Java ORB uses the Java Endorsed Standards Override Mechanism to coexist with other implementations.

When you install the IBM Java ORB, the CORBA API provided in ibmorbapi.jar, together with the properties defined in orb.properties, overrides the CORBA API from your SDK. The following properties defined in jre/lib/orb.properties cause the IBM ORB runtime implementation to be used by default: 

org.omg.CORBA.ORBClass=
                  com.ibm.CORBA.iiop.ORB

org.omg.CORBA.ORBSingletonClass=
                  com.ibm.rmi.corba.ORBSingleton

javax.rmi.CORBA.UtilClass=
                  com.ibm.CORBA.iiop.UtilDelegateImpl

javax.rmi.CORBA.StubClass=
                  com.ibm.rmi.javax.rmi.CORBA.StubDelegateImpl

javax.rmi.CORBA.PortableRemoteObjectClass=
                  com.ibm.CORBA.iiop.PortableRemoteObject

If you want to use another vendor's ORB runtime with IBM's CORBA API, change the appropriate values in the orb.properties file. The vendor should provide these values.

If you want to use your SDK's original CORBA API with IBM's ORB runtime, simply move jre/lib/endorsed/ibmorbapi.jar to a different directory. If you then want to use the IBM CORBA API for a particular Java invocation, set the Java system property java.endorsed.dirs to include the directory to which ibmorbapi.jar has been moved, followed by the standard endorsed directory (jre/lib/endorsed).
