Thanks Vincet and Sergiu. But After doing suggested
steps and i hit the url
https://localhost/mywiki/. I get http status 404 error(requested resource
not found). What i did is this
inside WEB-INF\lib
1)placed log4j-1.2.8 and slf4j-log4j12-1.6.1
2)removed log4j-over-slf4j-1.6.2,logback-classic-0.9.30 and
logback-core-0.9.30
inside WEB-INF\classes
placed log4j.properties
On startup, inside the tomcat logs
28-Apr-2012 18:50:05.468 SEVERE
org.apache.catalina.core.StandardContext.start Error listenerStart
28-Apr-2012 18:50:05.468 SEVERE
org.apache.catalina.core.StandardContext.start Context [/mywiki] startup
failed due to previous errors
Looks like there is some other jar too which is conflicting. As soons as
reverted back above steps , application runs fine.
Well you need to find out why it's failing…. :)
See

Thanks

What bridging? From log4j to slf4j? But when slf4j will try to write
back to log4,
won't it cycle back through this bridge? As I said, this jar
defines the same classes as the real log4j jar. One can't have two classes
with the same name in the classpath.
You're right. I thought you wanted to do this for our build. I didn't
understand you meant fixing the doc…
Fixed now.
Thanks

dependency, so it's not
included in that jar.
