NoClassDefFoundError even though .jar file is included

Question

Hi I have a weird problem where when I run my webapp, I get a NoClassDefFoundError

But when I check in Eclipse, I find the .jar file (Jnotify.jar) and it shows all the classes. Same case when I import the .war file of my webapp I see the classes in the dependencies.

What could be my problem?

Thanks!

You are not looking in the right pace. Please post how you run your webapp. — Sotirios Delimanolis, Oct 08 '13 at 17:24
Is it showing in class path? have you checked your Jnotify.jar included in application class path? — subodh, Oct 08 '13 at 17:27
I launch my webapp using tomcat. It does show correctly in the application class path — MangO_O, Oct 08 '13 at 17:30
yea its in there. Apparently JNotify comes with .dll files, I read that theres somewhere you have to put them but I can't figure out where — MangO_O, Oct 08 '13 at 17:52

I found what was causing the error:

JNotify has specific Library DLL, I was placing them corectly in java.library.path but the problem is Tomcat doesn't look for those libraries unless the corresponding .jar files are in Tomcat/lib.

So adding my jnotify.jar to tomcat/lib fixed my problems.
