Problems creating a jar

[Kevin Florish]

Hi

Am running Windows XP SP3

Have tried to create an executable jar file to run my database file against. The code works fine in Eclipse 3.4.1.

Manifest.mf contents
=============
Manifest-Version: 1.0
Main-Class: suncertify.client.ContractorApplicationStartup

Jar Creation
========
jar -cfvm code.jar Manifest.mf -C bin .

This seems to work fine and creates the jar file and shows all the classes and manifest in the output.

Jar Execution
=========

javaw -jar code.jar alone

This just gives me a beep and does nothing.

Is there anyway I can debug the jar to see the problem or can anyone spot a glaring error that I cannot see.

Thanks Kevin.

instead of

javaw -jar code.jar alone

you should use

java -jar...

Thanks Alec

I was using the example from Monkhouse book, should have checked the errata

Now I get a "Failed to Main-Class manifest attribute from code.jar" error when running

java -jar code.jar alone

Manifest File is called Manifest.mf and contains:

    
Manifest-Version: 1.0
Main-Class: suncertify.client.ContractorApplicationStartup

This along with my bin directory were in my SCJD base directory and I created the jar from the SCJD directory as follows:

jar -cfvm code.jar Manifest.mf -C bin .

All the files were displayed ok including the following 2 entries:

added manifest
adding: suncertify/client/ContractorApplicationStartup.class(in = 3867) (out = 1948)(deflated 49%)

Ah I needed to add a blank line to the end of the manifest file :O

Thanks Kevin.
