AW: [Linux-HA] Tomcat times out

[Ehlers, Kolja]

Hello all,

I have a general question about bash programming since yet I am not too
familiar with it. The isrunning_tomcat() function in the tomcat ocf keeps
returning an error code. This is the function:

	if wget -O /dev/null $RESOURCE_STATUSURL 2>/dev/null; then
		return $OCF_SUCCESS
	fi
	return $OCF_ERR_GENERIC

The problem is the if condition keeps returning false. I just dont get this
part:

wget -O /dev/null $RESOURCE_STATUSURL 2>/dev/null;

What does especially the 2 mean? I know that wget tries to connect to the
statusurl, but the wget responds is directed to dev/null so how can this be
true or false?

Thanks
