JBoss doesn't bind server ports in RHEL5?

[gghart]

Hi,

I've got a freshly installed RHEL5.3 workstation, jdk1.6 installed, and Jboss-5.0.0.GA installed. I went back to fresh install of Jboss with no applications installed and no configuration file changes, and it seems to start up ok using the 'web' server configuration - I see the java process running and the only error/warning in the server.log or boot.log is:

server.log:2009-01-07 03:09:12,886 WARN [org.jboss.annotation.factory.AnnotationCreator] (main) No ClassLoader provided, using TCCL: org.jboss.managed.api.annotation.ManagementComponent

However, it doesn't bind to port 8080 (as I expected based on the listen defined in server.xml), and the server doesn't accept HTTP requests. Since there aren't any obvious errors, I'm not really sure what to do to troubleshoot this?

Any suggestions?

I think that is is listening. Try "netstat -an" - then the "cweb2:webcache" entry should show up as "cweb2:8080"

Hi PeterJ,

You're right, I do see it on port 8080 with -an.

It's back to figuring out a Redhat issue I guess. I can see the port available through netstat, and locally I can telnet to 8080 to connect to it, but I can't reach it from another PC. iptables is stopped, so something else is in the way .. interesting, I'll have to work on that.

Thanks!

Have your seen this: https://www.jboss.org/community/docs/DOC-9531

Right again PeterJ! You can also see this in the netstat, if you know what to look for (in hindsight).

When you bind a local port netstat -a shows as:
tcp 0 0 :webcache *:* LISTEN

When you bind the 0.0.0.0 (all), it shows as:
tcp 0 0 *:webcache *:* LISTEN

I went back through the readme and installation guide, and all I saw in there was a passing reference to this in the run.sh syntax a few hundred pages into the install guide.

Thanks for your help!

That first entry with netstat -a should be..

tcp 0 0 hostname:webcache *:* LISTEN

The switch from binding to 0.0.0.0 to binding to 127.0.0.1 happened between 4.0.x and 4.2.x, so the 4.2.x readme files highlighted this change. But that information is missing from the 5.0 readme - I guess the developers felt that people were used to the localhost binding by now (so far I have seen 3 forum posts on this topic this week).
