RE: How to include jars and add them into the MANIFEST.MF/Class-Path

### RE: How to include jars and add them into the MANIFEST.MF/Class-Path attribute

Hi Matthew,

I also had the same problem, because I include some common jar files in the
ear file.  Hence I fully support your suggestion.  However, I seems to read
from somewhere that the manifest classpaths is not supported in certain
apps server, so I kind of wonder if this is a standard J2EE specification.

Anyway, would appreciate if you could send me the codes of your modified
war-plugin.  Lazy to do the cut and paste :)

As far as I can see, the CVS HEAD version of the war plugin does not
support
manifest classpaths for webapps

Now I can see how for a small project, it is convenievnt to use WEBAPP\lib
for webapps, but if I have a lot of webapps that use the same library, i
get
one copy of it in the ear for each webapp

For large projects, this will significantly increase the size of the ear
(unecessarily)

IMO manifest classpath is the best way to deal with shared libraries from
both webapps and ejbjars, so I am wondeirng if there is any plan to support
manifest classpath for webapps

I have a modified local version of the war plugin that works correctly with

<war.manifest.classpath>true</war.manifest.classpath>

Anyone interested. It was a simple copy & paste job from the ejb plugin.

Interestingly the serverside maven j2e tutorial uses
<war.manifest.classpath>true</war.manifest.classpath> even though AFAICT
there is no support for it currently
