+1 Netbeans is a great environment to work in and very easy to config
BUT when adding any library it is important to know which classloader you will be using
http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html
System - generally for libraries utilised during Tomcat bootup
Catalina - generally for libraries utilised by the Catalina container (you can configure in other webapp containers)
Common - generally for libaries which will be commonly used for ALL webapps
WEB-INF/lib - generally for libraries used for just the web application
When your app is looking for a class the search order is
a.. Bootstrap classes of your JVM
b.. System class loader classses (described above)
c.. /WEB-INF/classes of your web application
d.. /WEB-INF/lib/*.jar of your web application
e.. $CATALINA_HOME/common/classes
f.. $CATALINA_HOME/common/endorsed/*.jar
g.. $CATALINA_HOME/common/i18n/*.jar
h.. $CATALINA_HOME/common/lib/*.jar
i.. $CATALINA_BASE/shared/classes
j.. $CATALINA_BASE/shared/lib/*.jar
if you experience difficulty loading a class its because the class is being used by either Tomcat or a webapp or both
(its important to not load the same jar in more than one classloader path)
HTH,

Too much pain... get yourself Netbeans, doing everything by hand is near impossible.
In netbeans you can drop in your libs, make your JSP, debug it and deploy it.
Good luck

Subject: Question about lib folder of Webapps
Hi everyone
I'd like to build a JSP to use and show results of using Sparql + Jena + Pellet libraries.
I have set up a directory called MyFirstTestDir in [TomcatDir]\webapps.
Inside MyFirstTestDir, I have created a folder called WEB-INF which
has a folder called lib; So I have:
[TomcatDir]\webapss\MyFirstTestDir\WEB-INF\lib
inside lib, I have copied all the files in lib folder of jena download
+ pellet download.
Extremely appreciate your help with these questions:
Some of the Jena jar files and Sparql jar files share the same name; therefore I can not copy them directly to lib.
Could you please advise what should I do?
I am using winxp and tomcat 6.
Thank you in advance.

Try to find out why some files have same name, it's probably because
thay are the same share libraries, just put one copy of them :)
Because what you are doing is building a webapp licaiton, which has some
librarie, you need to know what libraries your are adding to your
application , why and how they react together. Most of the time it's not
important. But most of the time you add a library X + it's dependencies.
You then have to check
1) are those dependencies not already provided by tomcat? If so don't
add them to your WEb-INF/lib
2) are those dependencies already in your WEB-INF/lib in another version
number? Then find out which version you need.
