Hi, Markus.
I should have been clearer in my earlier message.
The names in your JAR manifest's Extension-List must refer to the
extension names given in the manifests for the JARs that formally define
those extensions. (Look in the JavaDoc for the Manifest class and click
on the "Manifest format specification" link near the top for a much
better and more complete discussion than what follows here.)
Briefly, the manifest for a true extension JAR needs to include (for the
mythical extension named TimsExt):
Extension-Name: TimsExt
and then your JAR's manifest can include
Extension-List: TimsExt
to refer to that extension.
The JAR that defines the extension TimsExt could be named anything, such
as markus.jar. The name of the JAR is not necessarily related to the
name of the extension which the JAR might define.
The key point here, though, is that the manifest in JDIC's jdic.jar does
not seem to define JDIC as an extension at all. So your JAR's attempt
to refer to an extension that way will not work.
Or, putting it another way, when your manifest refers to the extension
names jdic.jar (and friends) GlassFish is essentially doing what any
class loader would do in processing your JAR - GlassFish tries to find a
JAR in the class path that has a manifest containing
Extension-Name: jdic.jar
and there is no JAR in the class path that does that. Even if jdic.jar
is on the class path (by virtue of being in the Java SE extension
directory) there is still the missing piece of the Extension-Name:
definition that is absent in the jdic.jar's manifest.
(I do not think there is a restriction prohibiting dots from extension
names but I'm not absolutely positive about that. I'm just following
through with your example.)
Does this make sense?
