<a name="Tuscany_OSGi_bundles"></a><h2> <span class="mw-headline"> Tuscany OSGi bundles </span></h2>
<p>Tuscany is making good process in creating separate bundles. 3rd party jars are also available as separate bundles now. There are still some classloading issues regarding Dynamic-Imports, Meta-INF/services and OSGi runtime extensions. Here is an <a href="http://services.alphaworks.ibm.com/manyeyes/browse/data?q=tuscany" class="external text" title="http://services.alphaworks.ibm.com/manyeyes/browse/data?q=tuscany" rel="nofollow">overview</a> (either in text or visualized format) of the Tuscany bundle dependencies. For a minimal integration I did a step-by-step analysis of the bundles needed to create a SCADomain and a Contribution that uses implementationtype.osgi and binding.sca within an Equinox OSGi runtime. Below you will find lists of required bundles for certain functionality. These lists will be updated as needed.

<ul><li> adapted manifest in org.apache.tuscany.sca.3rdparty.org.codehaus.woodstox.wstx-asl_3.2.1.jar: add <b>Eclipse-RegisterBuddy: javax.xml.stream</b> to allow classloader to find STAX implementation
</li><li> added Ivans Fix to org.apache.tuscany.sca.databinding.jaxb.JAXBDataBinding (TUSCANY-2346), this is not included in current Tuscany code
</li><li> I provided a contribution for TUSCANY-2281 that solves the problem
</li></ul>
<a name="Adjustments_to_SMILA"></a><h2> <span class="mw-headline"> Adjustments to SMILA </span></h2>
<p>The following adjustments where made to SMILA classes/configurations:
</p>
<ul><li> enabled @AllowsPassByReference on org.eclipse.eilf.connectivity.framework.crawler.filesystem.FileSystemCrawler
</li><li> use classes="..." in &lt;t:implementation.osgi&gt; of .composite file to allow parsing of Annotations
<ul><li> as for Crawlers annotations are included in the implementation class and in the abstract base class AbstractCrawler it is important to add both classes to this list
</li></ul>
</li><li> Annotations are not processed on implementation.osgi, because the method processAnnotations(boolean doWait) of class OSGiImplementationProvider is never called. For testing purpose I just called it in the start() method of the same class. With this fix the annotation are processed successfully.
</li><li> adopted method getCrawler(final String crawlerId) of class CrawlerControllerImpl to make use of the fix provided for TUSCANY-2281

</li></ul>
<p><br />
</p>
<a name="SMILA_open_issues"></a><h2> <span class="mw-headline"> SMILA open issues </span></h2>
<ul><li> (<b>solved</b>) because of TUSCANY-2281 it is not possible to use more than one CrawlerComponent (e.g. Filesystem and Web). It is however possible to crawl multiple datasources on the same CrawlerComponent in parallel
</li><li> as long as SMILA is run inside of eclipse IDE everything works fine. I build an application and tried to run SMILA outside of eclipse IDE. I did not manage to get it to run and start a SCADomain.
</li><li> In general Component references are initialized on the first method call on a Component. Usually this is done on the SCA service reference. Our JMX management wrappers do not use a SCA service reference but a reference to the underlying DeclarativeService (see in org.eclipse.eilf.management.crawlercontroller.Activator). So SCAServices need to be created "somewhere" so that the references are initialized. Otherwise the underlying DeclarativeService has no references set. This can be achieved by using the Annotation @EagerInit on class CrawlerControllerImpl. This forces reference initialization at initialization time (and not at the first method call). This works with binding.sca. I don't know if this setup also works with binding.rmi. I guess it will fail, as no local DeclarativeService is available. I think we will always have to look up SCAService instead of DeclarativeService references. I will test this when I have finished the list of required bundles for binding.rmi.
