Issue with adding Jar files

Hi,

I have been trying to add the 'org.apache.poi' jar files to run a program to convert excel files to csv files. I read up on some articles and downloaded 'poi-bin-3.9-20121203.zip' and extracted it to C:\. I added the individual jar files to my ClassPath and tried running the program. I keep getting the error 'org.apache.poi.hssf.usermodel' does not exist. Could anyone please help me in understanding how to extract and add the jar files porperly? I am not using any IDEs and am running javac from my Windows command prompt.

Thanks in advance,
Benoy

You should the classpath flag in javac

javac -cp c:\poi.jar YourJava.java

Then try running it also need to specify classpath

java -cp c:\poi.jar YourClass

Then for jar creation

jar cfm YourJarName.jar YourClass.class poi.jar manifest.txt

In the manifest text specify the main class.
