I sent this off to inprise this morning....I'll let you know what response I get. (Oh man, I just noticed a type/think-o in there....s/thing/this/ towards the bottom.) I figured the mentioning of recent events couldn't hurt. Keith -- Keith T. Garner [EMAIL PROTECTED] STR Consultant http://www.str.com/ [EMAIL PROTECTED] "Be silent, my JIT" -- Dru Henke
The name of the thread of e-mail that you have been forwarded was titled: [[EMAIL PROTECTED]: Visibroker for Linux and JDK 1.1.6v2 problem] Dear Inprise: With the recent annoucements of Oracle, Informix, and Computer Associates Linux is beginning to gain the respect and recognition it has long deserved. Linux is the only non-Microsoft OS to gain market share in the past year and is a wonderful platform for development and for use as a server of all sorts. I've written you in the past asking you to consider porting the native portions of Visibroker for Java to the Linux platform, most notably the OSAgent. The response in the past is that there has not been enough interest in such a product. While that may have been true in the past, I think its becoming harder and harder to continue to give that answer with the recent changes in the industry. Attached to this mail is a recent thread that was on the java-linux mailing list. People are using the Visibroker package (minus the native ports) and are sometimes going through hoops to do it. People want to use the product in the wonderful developement environment that Linux provides. I argue that there is sufficient interest and people are awaiting this move from Inprise. (As a slight aside, I've been using Visibroker since I was hired at my current job a year ago, and I've been developing solely on Linux that whole time as well, and I can't tell you how much I would appriciate and welcome a Linux port. I also am fairly sure that a client of ours in the near future will be wanting to use the product on Linux as well as they make their move to the java world.) I thank you for your time reading thing, and, again, I strongly encourage Inprise to consider this request. Keith -- Keith T.

Hi: I get the following message occasionally from a client trying to talk to a CORBA server. Both client and server are built using Visibroker and running on Linux with JDK 1.1.6v2 (glibc 2.0.7-13). I added a message to the server which indicates that the server's impl method is being called, and obviously the error happens when the client tries to read back the server's reply. Anyone seen this or know what is going on?

Rather I'm running the commercial Visibroker for Solaris, but I tarred up all the files and copied them over to Linux and they work fine. Except for osagent (which is a Solaris native program), but you don't need osagent if you use URLNaming. I wrote to Borland about this and they said that was fine but (a) they wouldn't support it and (b) they wouldn't port osagent to Linux because of `lack of interest'. Yeah ... right ... Maybe you should write to them too and if enough people do it, then they will change their mind.

I guess my mail to them twice over the past 9 months must be lack of interest as well :) Anyway, I've got the same setup as Richard going on, except we are using OSAgent running on one of the NT boxes around here. Might as well put it to good use. Keith -- Keith T.

Richard, I hope you don't mind me asking but .... Where did you download it from, what was the URL ? How much space does it need ? Is it easy to install, what are the procedures you used ? I'm sure loads of people will be interested in this.. Many thanks Matt

Anyway, I solved it, and for reference here is the answer. It's nothing to do with the Linux JDK or JVM. It's caused by the server implementation method throwing a java.lang.* exception, in this case, it was a ClassCastException. Bizarrely, the server prints nothing. Instead, VBJ seems to pass the exception back to the client. The client, instead of doing the right thing, throws a wobbler -- it turns the undeclared exception into a CORBA.UNKNOWN and throws that instead! I caught this fairly easily in the end by wrapping my server method with a try { ... } catch (Exception ex) { ... }. There you go ...
