Problem with Declarative Service (DS) [message #93686]

Hi,

I've started to use Equinox Declarative Services but I've found two
problems:

- It's not possible to define two components in the same XML file (I'm
talking about the XML file referred in the Service-Component header of the
MANIFEST.MF). As a result, I have to create an XML file for each component
of a bundle. Is this the expected behaviour?.

- The most important problem is the following one. I have defined a
component with two service references. Each service reference defines two
methods: bind and unbind. I tried to use directly the service interface in
the bind/unbind method (in the Java code) but the behaviour was bad. These
methods were not invoked, although I checked that the services existed.
However, all changed when I included a org.osgi.framework.ServiceReference
instead of the service interface in the bind/unbind methods.

Does anyone practise with DS?. Should we wait for the "green" status?.

Are you using the DS from the incubator contributed by prosyst or the
original DS implementation in Equinox. If you are not using the prosyst
implementation please give it a try. You need to following projects
from the CVS repo dev.eclipse.org:/cvsroot/eclipse

equinox-incubator/org.eclipse.equinox.ds
equinox-incubator/org.eclipse.equinox.util

Please don't wait for a "green" status ;-) We need community help to
flush out any bugs. If you still find issues with this implementation
please open bugs against Eqiunox->Incubator. Thanks.

Tom.

Thanks Tom,

I used the Eclipse's implementation:
http://download.eclipse.org/eclipse/equinox/drops/S-3.3RC4-2 00706081718/download.php?dropFile=org.eclipse.equinox.ds_1.0 .0.v20070226.jar

Anyway, I'll try the CVS version and comment my results here.

Hi again,

I've just checked the Prosyst plugin (from CVS) and I suffer the same
problems. The main difference is that now (with the Prosyst plugin), I have
to start the DS plugin manually (I don't know why).

Anyway, I have to test it more carefully before opening any bug.

I've just opened a bug (it's my first Eclipse bug so I'm not really sure
that it's in the correct place):
https://bugs.eclipse.org/bugs/show_bug.cgi?id=198822

Finally, the bug is only related to the problem with two components in the
same XML component description. I've checked that it's possible in
Knopflerfish.

I haven't opened the other bug because currently it works (the most
important one). I cannot understand why it works now, because I didn't
change anything :(. Perhaps this problem will appear again in the future.
