Hi all:
Tomcat 3.3 (on linux) seems to be quite shoddily
developed. Surprising that, given it's high
visibility and posture.
Consider for instance:
I downloaded the binary distro of tomcat 3.3.
I have set and exported both TOMCAT_HOME and
JAVA_HOME. Compiled and installed mod_jk.so
too. (against Apache 1.3.22).
All I have to do is edit/configure the
"conf/server.xml" file and I should be well
on my way right ?
Well let' see.
shell> vi server.xml
shell> tomcat.sh start -jkconf
EmbededTomcat: exception initializing ContextManager
java.lang.NullPointerException at
org.apache.tomcat.facade.JspInterceptor.addContext(Unknown
Source)
[..bunch of stack trace crap here ..]
Hmm. The message above gives me *no* more information.
Nothing looks obviously wrong with the server.xml
file, let's validate it using the W3C validator.
But wait, there is *NO* server.dtd. There is only a
description in the manual which says:
----------- quote ----------
This is the main element in server.xml. It has a
single child describing the tomcat configuration,
ContextManager.
Examples
<Server>
<ContextManager >
... ( tomcat configuration )
</ContextManager>
</server>
ContextManager
------------- end quote ----------
Hmm. Well my file kinda looks ok, but not having a
DTD kinda means that the tomcat developers don't
understand the central concept behind xml. But's
let's leave that aside for now. Let's just validate
the *syntax* of server.xml using W3C (if the
structure indeed is as simple as the manual claims).
[fire up a browser, validate server.xml here]
Well, that validated fine. So why am I getting
the error and wh am I getting it? There is no
way to tell, either from the Exception, or
the LACK OF DOCUMENTATION.
2 hours later, after random permutations and
combinations of server.xml I still haven't found
what's wrong.
Attached below is the complete server.xml,
in case any of you are interested.
In the past, I may have gotten upset at having wasted
all this time. But that was before I found enlightment
through tomcat. Now I am at peace with the world for
tomcat teaches us about the futility of trying to
solve simple problems.
Of course, now that I have given up trying to make
this thing work, I do have some idle time to wonder:
Exactly what are the tomcat developers smoking ?
