creating and executing a jar file

[Em Aiy]

I am trying to create and execute a jar file. the jar file has few depencies. the manifest.mf file is

Manifest-Version: 1.0
Main-Class: com.e2e.otengo.util.Alerter
Class-Path: activation.jar commons-codec.jar commons-httpclient.jar commons-logging.jar log4j.jar mail.jar 

and when i try to run the jar file with following command

java -cp D:\alerter-jar\activation.jar D:\alerter-jar\commons-codec.jar D:\alerter-jar\commons-httpclient.jar D:\alerter-jar\commons-logging.jar D:\alerter-jar\log4j.jar D:\alerter-jar\mail.jar -jar node-alerter.jar

it gives me following error

Exception in thread "main" java.lang.NoClassDefFoundError: D:\alerter-jar\commons-codec/jar

What mistake am i doing? i am unable to get it working .. any help?

Don't know.

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

java -cp D:\alerter-jar\activation.jar D:\alerter-jar\commons-codec.jar D:\alerter-jar\commons-httpclient.jar D:\alerter-jar\commons-logging.jar D:\alerter-jar\log4j.jar D:\alerter-jar\mail.jar -jar node-alerter.jar

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.
