Cause

  • If you are running 0.6.2, you may have specified your db connection settings directly in resource/xplanner.properties. A bug in 0.6.2 build system makes it only look in resource/xplanner-custom.properties. Specify your db connection settings in resource/xplanner-custom.properties instead.
  • Otherwise, check your connection settings. This exception indicates that xplanner could not create a connection.

Causes

/etc/hosts is wrong. It had

/etc/hosts

It should be

/etc/hosts
127.0.0.1       localhost

(I couldn't figure out how to edit this page. I hope leaving a comment instead is ok. Emailing xplanner-devel@lists.sourceforge.net also fails.)

XPlanner fails to start.

log4j:ERROR Could not create an Appender. Reported error follows.
java.security.AccessControlException: access denied
(java.io.FilePermission /xplannerActivity.log write)
...
log4j:ERROR Could not parse url
file:/var/lib/tomcat5.5/webapps/xplanner/WEB-INF/classes/log4j.xml.
java.lang.NullPointerException

Environment

OS: debian etch (technically 2.6.18.8-domU-linode7)
JAVA: 1.5.0_14-b03 however, I installed 1.4, #update-alternatives
--config java, apt-get remove sun-j2re1.5, and then /usr/lib# ln -s
j2sdk1.4-sun j2sdk1.5-sun
when I type java -version I get 1.4, but for some reason when tomcat
starts it cites 1.5. I've even restarted the machine. eit. is this
the problem?
TOMCAT: 5.5
ARCH: i386
XPLANNER: 07b7-war

Symptoms:

I downloaded the xplannar war zip and went through the steps of
setting up the mysql database.

The tomcat web manager starts without xplanner running, though the
tomcat example apps are running. Click "start" fails:
FAIL - Application at context path /xplanner could not be started

catalina_2008-03-17.log msg is at the end of this email.

Let me know if I need provide any more information. Any help you can
provide would be GREATLY appreciated. I know this is more of a
environment setup issue than xplanner bug but I've been trying to
circumvent this obstacle for the past week.

Thanks,
Lucy.
