http://mango.serotoninsoftware.com/forum/posts/list/2.page JForum - http://www.jforum.net I have installed Mango 1.8 as the root application in tomcat6 on Fedora linux .
I changed the paths in log4j.xml and env.properties files in the
[mango]/WEB-INF/classes/ to a folder writable by the tomcat user.

I am getting an error in the tomcat6/localhost.log, saying mango cannot connect to the X server.
[code]
SEVERE: Exception sending context initialized event to listener instance of class com.serotonin.mango.MangoContextListener
java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

You might say that Mango should tell Java itself, but this is the first i've heard of this issue.]]> http://mango.serotoninsoftware.com/forum/posts/preList/322/1491.page http://mango.serotoninsoftware.com/forum/posts/preList/322/1491.page GMT Found the fix for headless mode, on Fedora 11. Edit /etc/tomcat6/tomcat6.conf and add the following
[code]
# To run our environment with a headless implementation,
# the follow property may be specified at the java command line:

JAVA_OPTS="-Djava.awt.headless=true"
[/code]

I get a bit further now, in that the folder mangoDB , and the mango.log file are created in /var/log/tomcat6.
I modified ROOT/WEB-INF/classes/env.properties
[code]
# db.url=~/../../mangoDB
db.url=/var/log/tomcat6/mangoDB
[/code]
and log4j.xml
[code]
<appender name="logfile" class="org.apache.log4j.DailyRollingFileAppender">
<!-- <param name="File" value="../logs/mango.log"/> -->
<param name="File" value="/var/log/tomcat6/mango.log"/>
[/code]

I am now getting the following error in the tomcat localhost file
[code]
SEVERE: Exception sending context initialized event to listener instance of class com.serotonin.mango.MangoContextListener
com.serotonin.ShouldNeverHappenException: java.io.FileNotFoundException: createTables.log (Permission denied)
.
.
Caused by: java.io.FileNotFoundException: createTables.log (Permission denied)

[/code]
Where is the path set for createTables.log

Thanks

[code]
# chown tomcat:tomcat /usr/share/tomcat6
[/code]

Mango now runs :-)

Mango does not recognise Firefox 3.5.8, as I get a complaint on the login page
[code]
Firefox 3.5 on Linux

However, I can login, and everything appears OK
