Hi All,
I'm trying to do a fresh install of Openmeetings 2.1.1 on a newly
configured Ubuntu 12.04 server. I go through all the steps, outlined
here
<https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CC4QFjAA&url=https%3A%2F%2Fcwiki.apache.org%2Fconfluence%2Fdownload%2Fattachments%2F27838216%2FQuick%2BInstallation%2BOpenMeetings%2B2.x%2Bon%2BUbuntu%2B12.10%2B-%2B12.04.pdf%3Fversion%3D1%26modificationDate%3D1361176041000&ei=4nLQUqX9Ecf-oQTEpoGYBA&usg=AFQjCNHiyGTdNBth172s2TG6aOvagVuk-g&sig2=BX_a-EvlAr-lYqDoiO8WxA&bvm=bv.59026428,d.cGU>
(the guide has lead me to many successful installations before) but I am
confronted with a null pointer exception error message the moment I
enter http://my.ip.number:5080/openmeetings/install, which reads as follows:
/HTTP Status 500 -/
/type Exception report/
/message/
/description The server encountered an internal error that prevented
it from fulfilling this request./
/exception/
/java.lang.NullPointerException/

/note The full stack trace of the root cause is available in the
Apache Tomcat/7.0.34 logs./
/Apache Tomcat/7.0.34/
From what I've read, it seems that this error is about as helpful as
saying "uhh my computer keeps crashing and I don't know why," but if
anyone might be able to through me some guesses as to what it might
mean, no matter how general, I would greatly appreciate it. I gather
that it means that it's trying to pass a null variable where there
should be a value but that's about all I understand of it.
Thanks so much!
Sam
