			Java and CORBA Resources & Links Object Management Group History and Analysis of OMG Java mapping-related specifications Quick Reference to OMG Java mapping-related specifications IDL to Java Mapping Spec 1.0 Postscript PDF FrameMaker This corresponds to the version of the specification used (and partially reprinted in Appendix A) by Programming in Java IDL. IDL to Java Mapping Spec: latest adopted (CORBA 2.2; roughly corresponds to OMG IDL to Java 1.1) Postscript PDF Java to IDL Mapping Spec Postscript PDF The Java to IDL Mapping Specification has been adopted by the OMG. It is not simply a reverse mapping based on the IDL to Java Mapping Specification; it is also a specification for using Java RMI over IIOP. ORB Portability Java Language Mapping (Java POA) Postscript PDF The IDL to Java Mapping Specification adopted by the OMG and used as the basis for Java IDL 1.1 and the first printing of Programming with Java IDL does not fully incorporate the portable stubs and skeletons that conform with the Portable Object Adaptor specification. The OMG has recently ratified the POA specifications, and now are in the process of revising the IDL to Java Mapping to take advantage of the now standardized POA. ORB Portability Enhancement/POA Specification Part 1: Postscript PDF Part 2: Postscript PDF Services Naming Postscript PDF Event Management Service Postscript PDF CORBA 2.2 Specification Sun Microsystems Note: Sun has removed the Java IDL 1.1 Early Access and Solaris Java IDL 1.1 FCS releases from its Web site. Sun Java IDL Java IDL for JDK 1.2 (Java 2) FCS Documentation JDK 1.2 (Java 2) FCS Download idltojava compiler (must be a member of the Java Developers' Connection -- free) OMG Specification Compliance Notes: From the JDK 1.2 documentation (http://java.sun.com/products/jdk/1.2/docs/guide/idl/mapping/jidlMapping.html): "These .java files are generated from the IDL file according to the mapping specified in the OMG document IDL/Java Language Mapping. We have included four chapters of that document here for your convenience. (You can see the whole document at IDL Java Mapping 1.0)." Also, at http://java.sun.com/products/jdk/1.2/docs/guide/idl/jidlUsingCORBA.html, Sun states that Java IDL for Java 2 (JDK 1.2) is compliant with the "CORBA/IIOP 2.0 Specification (orbos/97-02-25) and the IDL-to-Java Language Mapping (orbos/98-01-06 Final)." Other Java/CORBA Implementations That May Implement the OMG IDL to Java Mapping. Notice that most vendors claim to fully support the OMG standards, but for the most part neglect to mention which versions of their products support which versions of which OMG specifications. Iona OrbixWeb for Java From Iona's Web site: "OrbixWeb 3.0 fully supports the OMG standard IDL-Java mapping including wide-character/wide-string and the Java ORB Portability Interfaces. The portability interface guarantees client- and server-side application source-code portability, ORB replaceability and binary compatibility between stubs (generated by compliant IDL compilers) and ORB runtimes." We have verified that NPS 2.1.2 compiles with OrbixWeb 3.0 (Update 1 or later). However, we were not able to actually execute NPS 2.1.2 using a pure Iona runtime because of what we consider to be a non-compliance in Iona's specification and implementation of the CosNaming::NamingContext::rebind operation. From the OrbixWeb 3.1 release notes: "OrbixWeb 3.1 implements revision 1.1 of the OMG IDL/Java mapping specification." Inprise Visibroker for Java Inprise claims that Visibroker for Java implements the spec; we have verified that the code from Programming with Java IDL works with Visibroker for Java 3.2 and JDK 1.1.6. Expersoft CORBAplus, Java Edition Expersoft claims full compliance with the OMG IDL to Java Mapping Specification. OOC ORBacus This Java ORB is free for non-commercial use. It used to be called omniBroker. ObjectSpace JBroker This new Java ORB claims full compliance with the CORBA 2.2 specification, including the POA. It also claims Object by Value and Java to IDL Mapping support. Dais ORB J2 In March 1998, ICL was giving away their basic version of the J2 ORB, but have since pulled all downloads from their site. Oddly, the J2 ORB ships with a Trader service but no Naming service, which is an extra-cost add on. As of August 1998, DAIS apparently will be supported by PeerLogic. IBM Component Broker While this product has been announced for a long, long time, it seems perpetually to be available only as a pre-release. (Of course, the same could be said for Java IDL itself!) While their online developer's cookbook documents a CORBA interface, recent marketing announcements for this product stress its future as an Enterprise JavaBean container. jacORB This is truly a free Java ORB, covered by the GNU Public License. It has implementations of CosNaming and CosEvents. Paragon OAK Paragon claims full compliance with the OMG CORBA 2.2 IDL to Java Mapping Specification. Oak is primarlly an ORB for C++; Paragon supplies beta Java client mappings, but nothing in Java on the server side.
