Old example?
I tried to create GUI application with Felix. i downloaded example from
http://cwiki.apache.org/confluence/display/FELIX/Apache+Felix+Application+Demonstration
It runs very well and its exactly what I need.
But I tried to create my own application with actual version of Felix. I
found out that there are some changes .
For example constructor doesnt have 2 arguments but only 1
here Is old example from org.apache.felix.example.servicebased.host
<codeexample>
// Create list to hold custom framework activators.
List list = new ArrayList();
// Add activator to process auto-start/install properties.
list.add(new AutoActivator(configMap));
// Add our own activator.
list.add(new Activator());
try
{
// Now create an instance of the framework.
Felix felix = new Felix(configMap, list);
felix.start();
}
catch (Exception ex)
{
System.err.println("Could not create framework: " + ex);
ex.printStackTrace();
System.exit(-1);
}
</codeexample>
In actual version of Felix is only
<codeexamplefromsource>
public Felix(Map configMap)
{
</codeexamplefromsource>
So what is necessary to change in example code
org.apache.felix.example.servicebased.host ?
Thanks

Well, the change occurred in Felix 1.4.0 and remains backwards
compatible through the current release, so there was no reason to update
the documentation. However, I can add a note to make it more clear.

Yeah, but it is a bit confusing that it starts with the warning that
it is based on Felix 1.4.
I embedded felix 1.6 a few weeks ago and noticed some discrepancies,
but i see now that these are all fixed, so i guess it should mention
that it is based on 1.6 ;-)

I will try to update these examples today or tomorrow. Thanks for
reporting the issue. In the meantime, checkout:
http://felix.apache.org/site/apache-felix-framework-launching-and-embedding.html
This explains the new framework API.

FYI, I have committed versions of the examples that work with the 1.8.0
framework release...

You can take a look at the ASF's not quite final license policy:
http://www.apache.org/legal/3party.html
Although it's not formally finalized, it is essentially in use as
presented today and it shows the license environment as it presents
itself to us.
The Free Software Foundation comes from a different viewpoint. The
following page gives a glimpse at their perspective:
http://www.gnu.org/licenses/quick-guide-gplv3.html
In the end, when choosing a license, you have to ask yourself what you
want to accomplish. But going into any detail about this here is
off-topic for this list. I'm sure there are lots of additional resources
on the net.

Thanks for the comment. I'll look into that and will adapt the eclipse
template and present references if necessary. Feel free to use the
given example. The overall project of which the snippet was taken is
under development and the license discussion still has to start. Are
there any good web sites to provide a good comparison between suitable
licenses that are compatible with Felix?

Depends. ALv2 + GPL = GPL. If you're working in a GPL environment that's
not a problem. But GPL in the ASF is a no go.
