Have you really got 3 lines in the Manifest? There should be 4, the last line being empty.
I presume you have read the Java Tutorials section, where it says you must end with a line terminator character. Shouldn't you have all those jars in the classpath part of the Manifest file, rather than listing them at the command line?

I have solved the issue. and yeah - it was missing the new line :$ .. thanks
Another problem here is that you have space characters in the classpath. That's why the JVM thought "D:\alerter-jar\commons-codec.jar" was the name of the class you were trying to execute. But since you specify all the jar files in the manifest, there's no need to have a classpath here at all.
