dear friends,

how can i distribute the driver of the MySql within my JAR ?

 

 

You don't. You distribute it with your jar as a separate item.

 

 

ok, there is no way to include the driver jar into a single JAR ?

 

 

What's so difficult about distributing two files? Most software distributions contain far more files than that.

 

 

there are tools out there that basically provide a custom class loader to be able to load jars from within jars. one such one is

http://one-jar.sourceforge.net/

and there are others.

frankly, i'm amazed this isn't built in.

 

 

just technologic curiosity .... you know, pushing Java a bit ahead....

the stress: I need to distribute a ZIP, the user should unzip that and then run te application...

it seems much better the user download a single JAR whithout dependency of external tools...

 

 

Maybe it helps you :

Felipe,

I have posted a comment to your blog on this topic (the blog: http://weblogs.java.net/blog/felipegaucho/archive/2005/11/deliver_your_ja.html).

Thanks,

There's a tool called "GenJar", I found on sourceforge which will assemble a composite jar from a classpath by chasing class references. Runs as an ant task. You'd have to specify the driver class explicitly.

 

 

I usually use ANT to fuse all my jars in one with this task

<jar jarfile="myapp.jar" basedir="classes" excludes="">
 <zipgroupfileset dir="libs" includes="*.jar" />
  <manifest>
   <attribute name="Implementation-Title" value="${name}" />
   <attribute name="Implementation-Version" value="${version}-${build}" />
   <attribute name="Implementation-Vendor" value="${vendor}" />
   <attribute name="Created-By" value="${author}" />
   <attribute name="Main-Class" value="${main}" />
   <attribute name="Class-Path" value="${classpath}" />
  </manifest>
</jar>

 

 

Another option is to use a simple JarClassLoader: http://www.jdotsoft.com/JarClassLoader.php

 

 

I'm sure the above posters have all been waiting two years for your stirring response. Well done! Now they can get on with their lives.
