TC6 classpath problem...
Upgrading from TC5.5 to TC6 and having class path problems. We are
starting it via JSVC, we used to start it up with the following class path:
CLASSPATH=\
$JAVA_HOME/lib/tools.jar:\
$CATALINA_HOME/bin/commons-daemon.jar:\
$CATALINA_HOME/bin/bootstrap.jar
However with TC6, it requires
CLASSPATH=\
$JAVA_HOME/lib/tools.jar:\
$CATALINA_HOME/bin/commons-daemon.jar:\
$CATALINA_HOME/bin/bootstrap.jar:\
$CATALINA_HOME/lib/catalina.jar:$CATALINA_HOME/lib/tomcat-coyote.jar:\
$CATALINA_HOME/lib/servlet-api.jar:$CATALINA_HOME/lib/annotations-api.jar:$CATALINA_HOME/lib/jasper.jar\
:$CATALINA_HOME/lib/jsp-api.jar
just to start up, to get apps to run we have to list the entire contents
of $CATALINA_HOME/lib/ as part of the classpath value, this doesn't seem
right. Am I missing something obvious? Catalina.properties has:
common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar which I
thought should bring all the jars into scope....
Thanks!

Why do you have commons-daemon.jar on the -cp? None of the doc shows
that.

That looks like a <Context> element for one of your webapps is bad. If
the <Context> element is not in server.xml (and it shouldn't be), you
must not specify the path or docBase attributes.

Thanks for the pointer, I changed it to:
JSVC_CLASSPATH=\
$CATALINA_HOME/bin/commons-daemon.jar:\
$CATALINA_HOME/bin/bootstrap.jar:\
and passed $JSVC_CLASSPATH as the -cp command. It starts although I am getting some MBean errors, should this be picked up or do I need to extend the JSVC -cp beyond the basics above?

.......
Thanks!

That's odd, because every example I looked at and especially the actual
Tomcat doc itself shows only bin/bootstrap.jar, and that is specified by
the -cp command line option on jsvc, not the CLASSPATH environment
variable. You need that -cp of the one jar and a few desirable system
properties settings (look in the scripts for those), nothing else.
Setting that mess you had will certainly destroy Tomcat's expected
classloader hierarchy. Read this:
http://tomcat.apache.org/tomcat-6.0-doc/setup.html#Unix%20daemon
BTW, tools.jar has not been needed since the first release of 5.5.

I don't know how to get JSVC to start without it though, every example I can find of JSVC has the minimal classpath variables I listed. It won't start without it, likely as it bypasses the tomcat scripts you mentioned. What I am trying to figure out is why I have to list everything in /lib by hand, I thought Tomcat should pick those up on it's own based on catalina.properties....
Thanks!

Did you know that setting CLASSPATH to anything when starting Tomcat is
a capital offense?
Really, get rid of the CLASSPATH variable; it must not be used with
Tomcat, and should not be used with any Java environment beyond 1.0.
The Tomcat startup scripts take care of establishing the necessary
paths.
