Subject Re: tomcat start exception
Date Mon, 26 Sep 2005 16:18:11 GMT
Thanks very much for your big help. After adding the attribute,
catalina.out has no exception when server startup. But the same
exception now is appearing when server shutdown. In addition, if I try
to access server's manager page, catalina.out records exception as:
            An exception or error occurred in the container during the
request processing
             java.lang.NoSuchFieldError: debug

I still unable to access the manager page, just a broken link. Do you
have some ideal of that?

If you add the attribute channelSocket.soLinger="-1" to your AJP/1.3 
<Connector> element in server.xml, it should make the error go away. 
It's 
beyond me why Sun has decided to throw an exception here.
