Does rf-tools support comments in hql-editor?
For example, I write in the hql editor:
line 1: --select DAYNAME(timestamp) from Dates a
line 3: -- this is a comment
line 2: select DAY(timestamp) from Dates a
so you see, the first and second line should be ignored.
But it does not work.
I get this failure:
java.lang.IllegalArgumentException: node to traverse cannot be null!

Hi
I have a web application (war) running on jboss as 5.1.0. The bussiness model is that every client has running jboss as with deployed war file. What I want is when a new version of the war file is available every war file to be automatically updated so all the clients will have the newest version.
Is there any ready to use system for this purpose?
I read about clustering and farming, but the farming service doesn't work for me: First I have to build a cluster, which could not be possible if the instance of jboss is behind NAT and second all the war files will be undeployed if somebody deletes the war file from the farm directory.
I can bulid such system by my own and if so, is there any jboss services I can use to make it easily (like JMX to cause remote redeploy).
