Question

How do I install a 3rd party JAR file to my tomcat web application?

I have placed it in every folder I can think of, and am referencing it like:

import com.google.api.translate;

Is there a particular folder? I have tried WEB_INF/lib

Answer 1

If all apps on Tomcat need that JAR, the place to put it would be /lib if you’re using Tomcat 6.x or higher and /server/lib if it’s version 5.x or lower.

If only your app needs a 3rd party JAR, put it in WEB-INF/lib.

I hope you’re packaging your app as a WAR file.

I’d recommend reading a bit more about Tomcat and CLASSPATH before you proceed.

import com.google.api.translate;

This doesn’t look like proper Java to me. Shouldn’t that be:

import com.google.api.translate.*;

What is the name of the JAR containing those classes? Where did you find it?

Looks like you want to use Google’s translate API somehow.
