Third Party libraries in Tomcat

[Padma Prasad]

Hi,
I am using Tomcat for my application. My application has to display images so we are using javachart. As per the instructions, I have made classpath point to a jar file which has all the libraries for the javachart. so, I have no problems compiling a java file with chart library classes. But does Tomcat understand the system classpath? or do I need to specify some where so that tomcat understands that jar. I have put this jar file in tomcat-home/common/lib. But when I run the application, I get the exception NoClassDefFound for this javachart class.
How should I tell the tomcat to look into this jar file?
regards,
Padma.

It should be enough to put the jar file in the web application's lib folder.
'<tomcat_location>/webapps/<web_application>/WEB-INF/lib'

Jars that are specific to a single web app should be placed in that app's WEB-INF/lib folder (as per pervious post). For jars that will be shared across more than one app, I place them in $CATALINE_HOME/shared/lib.

Thanks Rene and Bear.
This also works by placing the jar in the $CATALINE_HOME/common/lib.
Thanks for the help.
Padma.

continuation to my previous reply...........
It works fine if the third party jar file is placed in the $CATALINE_HOME/common/lib. I tried this before but got an error coz I placed a wrong jar file. My mistake............
