SingleSignOn error in server.xml

["Brzezicki, Jerzy" <Je...@railinc.com>]

When I uncomment in server.xml line:

 

<Valve className="org.apache.catalina.authenticator.SingleSignOn"
debug="0"/>
 
I am getting error (below).
Has anyone had similar problem ?
I created testing environment for Tomcat 4.04 inside VAJ4.0 and I am getting
the error there.

How to compile Tomcat 4.0.3 with JBuilder?

[shi_hang <sh...@cvicse.com>]

I want to monitor the running of tomcat 4.0.3. 
As we known , JBuilder provides the such powerful functions like step , break point and so on.
But we must compile tomcat with JBuilder at first. Is there anyone can tell me how to compile tomcat with JBuilder?
Any help is appreciated.

Re: How does Apache access more than one application on Tomcat?

[Ashish Kulkarni <ku...@yahoo.com>]

Hi,
if u have set the communication between apache and
tomcat for one appication what u need to do is just
mount the other application
JkMount /maps ajp13
JkMount /maps/* ajp13

How do we do configuration so that Apache can access the applications on tomcat?
