Yes, Dan. But the OP stated he is using Windows Server 2008, which is the server version of "Vista". Since he doesn't say he's on 2008 R2 (which is Windows 7 Server), so we'll assume that he's at least at a Vista-level networking. The bug you mention is specifically about dual-mode socket support, that is, being able to specify the port and not the address and having Java set up to sockets which listen/talk on both the IPv4 & IPv6 addresses of the machine. At least if I read it correctly. Re-reading it, it might not be there for NIO, no matter what you try. My work-around would specifically show whether the support is there or not for IPv6 in NIO, i.e., use it as a diagnostic tool, if nothing else. But yes, reading the bug, really closely, makes it appear that the support for NIO IPv6 was not back-ported to JDK6 until this last July, specifically 6u33-b34. So the OP should probably start up upgrading his Java to jdk1.6_34 or later and see if that doesn't fix it first. Personally, I prefer the APR to NIO, but mainly because SSL is easier to manage under APR. I believe there are some esoteric advantages to using NIO, but I'd have to go back to the comparison chart to tell you what they are. The OP may have a specific use case that requires those features. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
