Why is my jar producing a NoClassDefFoundError when the class is listed in MANIFEST.MF?

I have created jar in the following folder usr/local/bin/niidle.jar and my MANIFEST.MF file is as follows:

  Manifest-Version: 1.0
  Main-Class: com.ensarm.niidle.web.scraper.NiidleScrapeManager
  Class-Path: hector-0.6.0-17.jar

I verified that the file hector-0.6.0-17.jar is also present in the folder:

/Projects/EnwelibDatedOct13/Niidle/lib/hector-0.6.0-17.jar

I don't want to give full class-path name in MANIFEST.MF file, because I have to run this jar on another machine. So I gave only jar file name Class-Path=hector-0.6.0-17.jar in MANIFEST.MF file.开发者_C百科

In spite of mentioning the Class-Path in MANIFEST.MF file, when I run this using command:

java -jar /usr/local/bin/niidle.jar arguments...

It is showing the error message:

--Exception in thread "main" java.lang.NoClassDefFoundError:

Please give me a solution for this error message.

Class-Path is relative or absolute to the directory where your jar file is located. so for your case you have to hector-0.6.0-17.jar to /usr/local/bin
