However, we now have a requirement to run the client remotely via a dial-up link, which is the other side of a firewall. We have configured the firewall to allow CORBA messages, but following the initial connection, we see the client trying to use the server's internal IP address, which of course is not available outside the firewall. After checking the JacORB documentation, I tried to use the "jacorb.ior_proxy_host" property, but that didn't solve it. Has anyone had this same problem and managed to get it working ?

Can you provide more details on what is going wrong? Another good place for this question is the jacorb-developer mailing list. <commercial> In the general case, the only solution is a full-fledged IIOP proxy that can handle firewall traversal including nasty details such as Network Address Translation (NAT), Callbacks, dynamic port assignments etc. If you are interested in an ORB vendor-neutral and high- performance IIOP firewall, let me know. (Actually, Xtradyne's "IIOP DBC" is the only such product on the market). </commercial> Regards, Gerald. -- Dr. Gerald Brose mailto:brose (AT) xtradyne (DOT) com Xtradyne Technologies http://www.xtradyne.com Schoenhauser Allee 6-7, Phone: +49-30-440 306-27 D-10119 Berlin, Germany Fax : +49-30-440 306-78 Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AppletTalk.com Forum Index -> Java and CORBA All times are GMT Page 1 of 1   Jump to: Select a forum Java Newsgroups----------------Java DiscussionsWeb-based java games comp.lang.java 3D Graphics API's for Java Java: Support and criticism Java System Announcements comp.lang.java.api JavaBeans Java and CORBA Java and Databases comp.lang.java.developer Java GUI Toolkits Java Help comp.lang.java.javascript JVM, native methods and hardware comp.lang.java.misc Java Language Programming Security and Java comp.lang.java.setup Java Software Tools comp.lang.java.tech ibm.software.java.linux  Non-English Java Newsgroups----------------Java Language (German)Language Java (Français)Java (Italian)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
