java.lang.NoClassDefFoundError error

[jill Na]

Hi,

I have recently installed java on ubuntu.
But I am starting with Java after a long time now. Please help me ...

I have been getting this error -

java.lang.NoClassDefFoundError: org/apache/commons/fileupload/servlet/ServletFileUpload

I am using these jar - /commons-fileupload-1.2.2 and commons-io-2.0.1.jar:

which I believe might be due to incorrectly set CLASSPATH ??

How to fix it?

Could you please help me with configurations I need to set up - I am listing what I know - please correct or add to it.
1 the /etc/environment file should have this
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.24/jre"
CLASSPATH="/usr/lib/jvm/java-6-sun-1.6.0.24/lib:/home/xyz/commons-fileupload-1.2.2/lib/commons-fileupload-1.2.2:/home/xyz/commons-io-2.0.1/commons-io-2.0.1.jar:"

what else should I set up?

there is a build time classpath and runtime classpath.
You are printing your build time classpath - that is the classpath used when you build your code.
If you are deploying your code, put the JAR in the WEB-INF/lib directory and try again.
