Bundle-NativeCode question...
Hi All,
I have my native libs for each OS in separate jars and in some cases I have
quite a few jars. I have some simple questions
1. Can I keep my native jars as separate bundles?
2. Can I use *.dll in the manifest instead of naming every library?
3. What is the osname for Windows 7?
Bundle-NativeCode: *.dll; osname=winxp; osname=winvista; processor=x86
Thanks,
-Tony

True. Technically, you can package them in fragments and have the
framework merge them back into the bundle containing the dependent
native classes. I don't regularly think about using fragments. :-)

I always thought that you can package them in different fragments if you want. Admittedly, fragments are not "separate bundles" in the sense that at deployment they form one logical bundle, but they can be physically distributed as different jar files.

Thanks if I find a reference for use of Web Start you will be the first to know.
I just heard that Web Start has problems with SOCKS Proxy. Hopefully OSGi does
not have issues with that type of proxy.

In OSGi, native libraries must logically be packaged with the classes
that depend on them. As Marcel reminded me, you can use fragments to
avoid physically packaging them in the same JAR file, but the end result
is the same as if they were physically package together, i.e., you must
end up with the correct native libraries attached to the host needing them.
For example, assume you have two bundles needing native libraries, host1
and host2. Further assume you have native libraries for Linux and
Windows. You would need 6 different bundles that would be as follows to
the different platforms:
* Windows:
o host1.jar + frag1win.jar
o host2.jar + frag2win.jar
* Linux
o host1.jar + frag1linux.jar
o host2.jar + frag2linux.jar
This avoid duplication at the expense of having more artifacts to manage.

There are people who have done it, but I don't know of an example on the
web...if you find one, let me know and I can add a reference to our FAQ.

In OSGi, native libraries must logically be packaged with the classes
that depend on them. As Marcel reminded me, you can use fragments to
avoid physically packaging them in the same JAR file, but the end result
is the same as if they were physically package together, i.e., you must
end up with the correct native libraries attached to the host needing them.

* Windows:
o host1.jar + frag1win.jar

o host2.jar + frag2linux.jar
This avoid duplication at the expense of having more artifacts to manage.

Re: Bundle-NativeCode question...

First off thanks Richard for your prompt replies.
What I did using web start was have seperate bundles for each OS/arch for the
swing client so there is no duplication. I kept the java classes out of the
native lib jars for web start. So do I have to duplicate the bundles with the
classes since those are not OS dependant? I never thought about that because web
start allows you to have jars that are used for all OS's so no duplication
occurs.
Is there an example of using web start with osgi out there? Seems like a small
launcher class of some sort would be used.

-Tony

Yes, you can create separate bundles for each native platform (i.e.,
classes + libs for Windows, classes + libs for Linux, etc.). You end up
with a bunch of duplicate content and more artifacts to manage, but the
individual artifacts will be a little smaller.

Yes, you can create separate bundles for each native platform (i.e.,
classes + libs for Windows, classes + libs for Linux, etc.). You end up
with a bunch of duplicate content and more artifacts to manage, but the
individual artifacts will be a little smaller.

Re: Bundle-NativeCode question...

Okay the reason I asked about the *.dll because I have over 200 dlls. I can
write a program that reads the libs and creates the names with the ; for the
manifest file I guess.
When I said separate bundles I meant one for native dlls for windows, one for
linux and one for the mac.
So I can not do that? I am hoping like Web Start Felix will download the bundle
with the native libs for the OS and arch the client is using not all the bundles
for each OS. That is why I would have a native bundle for each OS.
One last question. Does Felix/OSGi download the jvm if one is not present? So
for a first time user of an app using OSGi/Felix will the jvm be loaded using
some attribute of a bundle?
Thanks,
-Tony

Can't remember the reference but osname=win7 will work. So will win32 actually if they happen to use the same dlls.

Hi All,
I have my native libs for each OS in separate jars and in some cases I have
quite a few jars. I have some simple questions
1. Can I keep my native jars as separate bundles?
2. Can I use *.dll in the manifest instead of naming every library?
3. What is the osname for Windows 7?
Bundle-NativeCode: *.dll; osname=winxp; osname=winvista; processor=x86
