Hi gurus,
i guess it is a good question. I added an external package (
org.apache.commons ... ) into my project since my servlets need it to run.
My project was developed with JDeveloper and then, i added a command line
like "package org.apache.commons... " at my servlet "BancoServlet" to allow
package's classes access. It runned fine, but whenever i put my application
in TomCat environment, inside GUIA directory, i get the following error. So,
first of all, what this message means and then, what should i do to fix it?
Thanks again in advance,
Euclides.
