I Can't Create my Jar File

[Adeyi]

I have a package called voiceexpert which contains three classes: Disease, DiagnosingEngine and Symptoms which is a JavaBean. Symptoms makes use of Disease and DiagnosingEngine objects.

voiceexpert is stored in the directory: c:\diagapp3

I compiled Symptoms.java as below:
c:\diagapp3> javac -d . Symptoms.java

The class files for Disease.java, DiagnosingEngine.java and Symptoms.java are placed in the directory: voiceexpert.

I created a Manifest.txt file inside c:\diagapp3 containing the following:

Main-Class:voiceexpert.voiceexpert.Symptoms

Name:voiceexpert/Symptoms.class

Java-Bean:True

I later created the jar file with the command:

jar cfm jjj.jar Manifest.txt *

But, I am having the error message: invalid header field

What can I do to remove this error?

Note: I created the Manifest.txt using utf-8 encoding. My code is to be used in a third-party application and that is why it does not contain a main method.

Hi dude!You forget to keep most important & starting header
"Manifest-Version: 1.0" just keep this as a starting header in your manifest.txt or manifest.mf file.It'll work.

I have modified the contents of the manifest file to contai:

Manifest-Version: 1.0

Created-By: 1.6.0 (Sun Microsystems Inc.)

Name: voiceexpert/Symptoms.class

Java-Bean: True

Yet, it gave the error message:
invalid header field name: Manifest-Version

What exactly could be wrong?

Note: I am using jdk1.6
