Subject Re: Help! Tomcat crashing on takeoff
Date Sat, 13 Dec 2014 09:27:26 GMT
Tomcat has few fallback approach for
 1.First it look at system properties for config url, with property name
 2.If it could not find in step-1, it looks at CATALINA_BASE/conf/
 3.If it again could'n find above, it tries to load it from the classpath
of bootstrap classloader.
 4.If it couldn't find even there, it will spit a WARNING log.

Given that:
  a. as you mentioned 2nd  is not a problem and
CATALINA_BASE/conf/ have valid common.loader values
  b. 3rd should not be a problem, because as can be seen bootstrap.jar is
there, and if everything is okay, should be included
inside it(you can verify it by unzipping the bootstrap.jar and sneaking at
  c. and finally you don't see any warning log

I will imagine you are passing "catalina.config" as a system property,
which is pointing to a which doesn't have a valid
common.loader value. And if this is not the case, then catalina.jar which
is being picked us is corrupted and doesn't contain
org.apache.catalina.startup.Catalina. This you can verify by manually
sneaking into the jar, by unzipping it.

Apart from these, there is little else which I could imagine is a problem.
And off-course these are all under the assumption that you are using
standard distribution and haven't tweaked with the build process/or even
customizing the code.

Also, I will suggest you past your catalina.log somewhere for us to see,
probably you may be missing something?
