1. Re: NullPointerException /jmx-console/HtmlAdaptor
etfromnu Jul 14, 2003 8:04 PM (in response to damski)I am having the same problem, but all of the fields are not updating. Most of the fields that I test still update but the SiteName property will not update. A trace of the exception that is being thrown is attached below. Has anyone else encountered this problem? I just installed the jboss-3.2.1_nukes-1.0.0alpha bundle on Windows XP Home and haven't made any significant modifications thus far. Any help would be greatly appreciated.
Thanks,
Eddie

I already tried to change the attributes that were initially set to null to some dummy values but that didn't seem to work either. I'll keep hacking away at it though. -

damski Jul 15, 2003 3:39 AM (in response to damski)I haven't had time to really look at this. My guess, since it doesn't appear to be OS dependant, is that it must have something to do with permissions on the SQL db - not sure, maybe a developer might drop a hint.....
