Q: Adding classes to a node
Hello there,
is it possible (in Tuscany 1.6) to add classes to a node without having
to package them in a composite? Or add them to the domain so that they
will be available to all nodes in the domain? I. e. I want to say something
like node.addToClasspath(<pathToJar>)
Alternatively, I could imagine building a composite with a component that does
not offer any service at all, but simply contains the classes, to be deployed with
separate composites that add whatever service definitions and bindings are
relevant for a node. Would this be possible, i. e. could I completely separate
the component and service definitions in different *.composite files?
Background:
I have a composite (packaged with all the classes) in Eclipse project 1.
In another project 2 I simply define a second *.composite file that gives the
the service from jar1 a different binding.
I would prefer not to include the classes from project 1 in the jar file of
project 2 (in case they are run in the same JVM, I handle this case with
import.java/export.java in the META-INF/sca-contribution.xml).
I also do not want to deploy the jar of project1 in my node, because I do not
want the node to make the service available over those bindings.
So, in order to avoid a ClassNotFoundException, I would simply want to add
the jar 1 to the class path of the node running the service from jar 2.
But neither the SCANodeFactory nor the Node or SCADomain have this
capability.
To me, it seems a reasonable thing to do, and I believe it is possible in
Frascati, at least the screenshots from their domain manager suggest so.

If you use a zip format contribution then the zip may contain jars
which will be included on the classpath of that contribution. For an
example fo that see:
https://svn.apache.org/repos/asf/tuscany/sca-java-1.x/trunk/itest/contribution-folder/
In the 2.x code there is an API that allows specifying an external
sca-contribution.xml file when installing a contribution, that enables
installing any arbitrary jar as a contribution and having an
sca-contribution.xml side file define which classes in that jar are
exported and so available to other contributions in the domain. Any
chance you can move up to the 2.x code?

You can just add these jars to the classpath. In a web app, copy them into WEB-INF/lib.

thanks for the links, Luciano. I dare say I am confused about
many things. So I will put a simpler question:
If my contribution depends on additional libraries (jar files
for which I do not own the sources), how do I package these additional
libraries with my contribution for deployment in an SCA
node?

Not sure if you are overloading the term "composite" above where it
really means a contribution.
Anyway, the following integration tests might be of some help.
https://svn.apache.org/repos/asf/tuscany/sca-java-1.x/branches/sca-java-1.6/itest/contribution-import-export/
The store tutorial also provides some deployment scenarios similar to
what you have mentioned.

Not sure if you are overloading the term "composite" above where it
really means a contribution.
Anyway, the following integration tests might be of some help.
