Re: Exception using Tomcat4.0 Manager

[Craig R. McClanahan]

99% of the cases of this exception that I have seen are caused by having a
copy of servlet.jar in the Java system extensions directory
($JAVA_HOME/jre/lib/ext).  You should not have it there.

 Craig,
   Thanks for the reply. The servlet.jar file was in the jre/lib/ext
directory! I took it out and restarted tomcat, but came up with the same
problem. I also did a find on servlet.jar in TOMCAT_HOME and found only the
one instance in common/lib. I reset my CLASSPATH (which should not make a
difference, but I did it anyway) and restarted tomcat - same message.

  Any other suggestions would be appreciated.

RE: Exception using Tomcat4.0 Manager

[Cox, Charlie]

I received this error when I didn't have the manager context defined in the
virtual host that I was trying to use to connect to it. I did have it
defined for another virtual host, but it needed to be defined for each vh
where I was using it.

One thing that I have noticed that is not in the documentation is that
manager commands  apply to the current virtual host, not to all instances of
the 'path'. So in cases where you share the same context for different
virtual hosts with the same path, each needs to be reloaded(start/stop/etc)
from its own virtual host. 

I think this is important and should be clarified in the documentation as it
just appeared to me that the manager was not working(context was not
reloading) when actually I was using manager from one virtual host(what I
consider my primary vh) and trying to load a page from the other. After
playing around with it, I finally figured out what was going on.

yes, I realize now that the manager/list does say 'listed app for virtual
host xxx',but to me at first glance I just thought it was listing the
contexts for any virtual host as I hadn't at that time turned off the
auto-loading of contexts in my webapps directory. 

And it does make sense once you think about it...but I guess for some reason
I think of 'manager' as a tomcat-level admin tool, not a virtual host-level
context providing admin features.

RE: Exception using Tomcat4.0 Manager

[Mark Saltzman]

Just this morning I figured what the problem was. I had my own
server.xml file   that did not have the manager context defined. The line I
put in was (from tomcat4.0.1 final release):


The privileged=true is the attribute that made it all work.

I did receive 2 responses that referred to other possible solutions.
1) Someone said they saw this problem if servlet.jar was in
$JAVA_HOME/jre/lib/ext
2) The manager context must be defined in each Virtual host for it to apply
to all the contexts in that host and only that host.

good luck,

mss

Mark,

I saw your posting on the tomcat4 mailing list concerning the internal
server error on manager servlet.  I am experiencing the same problem.  I was
hoping you had found a solution to this problem since I didn't see any
replies posted to your message.  If you did find a solution could you send
me a reply with the steps to correct the problem.  Below is the specific
error:

javax.servlet.ServletException: Error allocating a servlet instance 
Root Cause:
java.lang.SecurityException: Servlet of class
org.apache.catalina.servlets.ManagerServlet is privileged and cannot be
loaded by this web application
