My .jar file is not working in java

I have created an application and it is working correctly when I am executing it through NETBEANS.

After that I had clicked on "Clean and Build" to build a SiteScrapper.jar file. Now when I am executing it through command prompt by invoking the following dos command:

java -jar "SiteScrapper.jar"

I am getting the following exception

sitescrapper.Main class not found

My Main class is located in the following package

com.innoConsulting.sitescrapper

In Netbeans either run the project (and it will ask you for the Main-Class) or go into the Project | Properties | Run and select the Main-Class.

Then do another clean and build and it will generate the JAR file with the appropriate manifest file (with the Main-Class: set).

Make sure that the jar file is 'executable'. The Manifest needs to have the Main-Class attribute.

You need to include a manifest file. See here for a quick explanation: http://www.skylit.com/javamethods/faqs/createjar.html

Your JAR needs a META-INF/manifest.mf file that spells out where the main class is.

You need to check the value of Main-Class in the Manifest file.
