Subject RE: unable to execute JAR file
Date Wed, 18 Jun 2008 13:10:03 GMT
Thanks for all reply.

Now what I did is I compiled only one source file and made a jar out of
it which contains only one ArrayExample.class file. Once JAR available
then I unzipped that JAR and edited the manifest file as per your
suggestion but still I am getting same error.

Please find the attached java source file and manifest file.

Please help

Regards
Irfan.

Does the jar have a manifest file that specifies the main class that
needs to be executed when you execute it?

 

When you create a jar it will have a META-INF directory inside which you
need to place a manifest file that has the main class that needs to be
executed when you execute the jar file. 

 

Just google about the manifest file and you will get your answer

 

-t

Subject: unable to execute JAR file

 

Hi All,

 

I have 10 java files and I have written Ant build.xml to compile and
create JAR file which contains the .class files. Now my requirement is
that I need to execute/install the JAR file but unfortunately I can't do
this as I am getting following error.

 

D:\Irfan\Manvendra Singh java code\Manvendra Singh java code>java -jar
test.jar

Failed to load Main-Class manifest attribute from

test.jar

 

D:\Irfan\Manvendra Singh java code\Manvendra Singh java code>

 

Please find the attached java code and build script.

 

Please help

 

Regards

Irfan.
