Making a JAR

Hi,

I am making a JAR file for a program in Swing. The Swing application
uses 5 external Jar files. Im having problems creating the manifest
file correctly and when i get my jar made, it cant find the main
class. Below is the mamifest file it contains the main-class variable
and the class path variable(I use this to point to the external jars,
if this is the incorrect way of doing it please let me know).

Manifest-Version: 1.0
Main-Class: start.Start
Class-Path:
C:\Sun\jwsdp-2.0\jaxb\lib\jaxb-xjc.jar;
C:\Sun\jwsdp-2.0\jaxb\lib\jaxb1-impl.jar;
C:\Sun\jwsdp-2.0\jaxb\lib\jaxb-api.jar;
C:\Sun\jwsdp-2.0\jaxb\lib\jaxb-impl.jar;
C:\Sun\jwsdp-2.0\sjsxp\lib\jsr173_api.jar;

Cheers
Patrick

Does the jar contain a class with path & name of
start/Start.class ?

I think it is. The paths should be relative,
not absolute..

>Manifest-Version: 1.0
>Main-Class: start.Start
>Class-Path:
> C:\Sun\jwsdp-2.0\jaxb\lib\jaxb-xjc.jar;

..so if the main jar lives in.. 'jaxb', that path would be..
lib/jaxb-xjc.jar
..note the forward slash, and lack of ';'. The example
in the JavaDocs shows two jars listed on the same
line, delimited by a space.

you can save yourself much trouble by using NETBEANS to build your jar
files. then open the jar file and see what's inside, that way you'll
learn how to create one yourself seamlessly
