Resin 4.0 will only start in console mode

[MrCoffee]

Hi,

I've just installed Resin Professional 4.0.10 on my Linux server, and I'm unable to start it as a daemon. When I try starting it up (logged in a root) like this:

/usr/local/jdk1.6.0_21/bin/java -jar /usr/local/resin/lib/resin.jar -root-directory /var/www -conf /etc/resin/resin.xml -log-directory /var/log/resin/ start

... nothing happens for about a minute, and then the following message is displayed:

Resin/4.0.10 can't start -server '' for watchdog at 127.0.0.1:6600.
java.lang.NullPointerException

When I try running "/etc/init.d/resin start", the same thing happens, except the failure message is:

Starting resin: failed!

However, when I start Resin in console mode, like this:

/usr/local/jdk1.6.0_21/bin/java -jar /usr/local/resin/lib/resin.jar -root-directory /var/www -conf /etc/resin/resin.xml -log-directory /var/log/resin/ console

... it starts up and runs fine.

Any idea why Resin would be working in console mode, but not as a daemon? Is there any way I can obtain more verbose failure messages, or is there a log I could look at?

Thanks!

Hi,

Do you see anything in /var/log/resin? If there were a stack trace for the NullPointerException in watchdog-manager.log, that would be really useful.

Thanks,

Hi Emil,

I realized what the problem was shortly after posting this question -- an older installation of Resin 3.1 had been running as a deamon, and this seemed to be preventing Resin 4.0's watchdog from starting up. Once I shut down resin 3.1, everything was fine.

(I wanted to post an update indicating I'd solved the issue, but my original post didn't become visible until this morning, so I guess you beat me to it!)

Thanks for your reply.
