RE: [Mav-user] Howto: Getting the JSP Example Working

 Thousand thanks for your tip. I got this error when I start up the
Tomcat:
 log4j:ERROR No appenders could be found for category
 (org.infohazard.maverick.Di
 spatcher).
 log4j:ERROR Please initialize the log4j system properly.
 
 What does it mean???

It means that the logging system is not initialized :-)  Scott included
a link to the FAQ in his email:
http://mav.sourceforge.net/maverick-manual.html#N10722

If you do not desire detailed logging information, feel free to ignore
the message.

 And when I run the friendbook example, the following problems
happened:
 
 javax.servlet.ServletException: Servlet.init() for servlet jsp threw
 exception
   at

org.apache.catalina.core.StandardWrapper.load(StandardWrapper.java:875)
   ... ...
 
 Root Cause:
 java.lang.SecurityException: sealing violation
   at java.net.URLClassLoader.defineClass(Unknown Source)
   ... ...

Hmmm, sealing violations.  I have heard much about these but not
experienced them myself.  Which exact versions of tomcat, jdk, and xslt
processor (if you're using one) are you using?  And what is the
remainder of the Root Cause stack trace?

I've got to admit that that stack trace doesn't offer me any clues.  You
should probably upgrade to the 4.0.3 version of Tomcat, because there
are some security issues with prior versions.  I would also try updating
to the latest version of Xalan (you are using xslt, right?).

Switching to JDK1.4, of course, is an option :-)

Does anyone else understand sealing violations?

Jeff

 Dear Jeff... :)
 
 I am not sure which version xalan and I am using.
 but tomcat is 4.0, jdk is jdk1.3.0_02
 and this is the whole page of exception (man... :))
 
 To ease the pain, do you think I should switch the whole thing to
jdk1.4??
 thanks.
