Hello,
Looks like currently tuscany supports just the file:// protocol only for
loading contributions- see
org.apache.tuscany.sca.contribution.service.impl.PackageTypeDescriberImp
l.getType() below.
Are there plans to support http:// protocol for loading composites
hosted externally?
-------
public String getType(URL resourceURL, String defaultContentType) {
URLConnection connection = null;
String contentType = defaultContentType;
if (resourceURL.getProtocol().equals("file") &&
FileHelper.toFile(resourceURL).isDirectory()) {
// Special case : contribution is a folder
contentType = ContentType.FOLDER;
} else {
contentType = resolveContentyTypeByExtension(resourceURL);
if (contentType == null) {
try {
connection = resourceURL.openConnection();
contentType = connection.getContentType();
if (contentType == null ||
contentType.equals("content/unknown")) {
// here we couldn't figure out from our registry
or from URL and it's not a special file
// return defaultContentType if provided
contentType = defaultContentType;
}
} catch (IOException io) {
// could not access artifact, just ignore and we
will return
// null contentType
}
}
}
return contentType == null ? defaultContentType : contentType;
}

Subject: RE: loading composite from url
Raymond,
Thanks for your help so far.
I have run the tutorial - at least the store node... I have yet to
understand how things are launched through node launcher ... some
documentation may help.
However, here is what I need to be done and the approach I would like to
take.
1. Lunch sca domain from a servlet. - Do I need the TuscanyServletFilter
in web.xml?
2. Initialize sca domain with artifacts from the runtime of my web app -
all classes are read through DefaultSCADomain.
3. Initialize sca domain with ConsumerFacade.composite served from an
external URL - as a result all the properties values from the
ConsumerFacade.composite will be injected into the referenced classes.
My approach is to:
1. set system property "org.apache.tuscany.sca.host.embedded.SCADomain"
to my own class - a copy of DefaultSCADomain.
2. Add a new method static SCADomain createNewInstance(String domainURI,
String contributionLocation, URL... composites) {
3. Anything else?
Am I on the right track? Would you do this?
Thanks,

Subject: Re: loading composite from url
Hi,
Are you trying to load and run a SCA composite remotely from a HTTP URL?
SCADomain class is not designed for this purpose. We now have the
NodeLauncher which can launch a SCA node to run a deployable composite
with required contributions.
Please see an example at:
https://svn.apache.org/repos/asf/incubator/tuscany/java/sca/tutorial/dom
ain/launch/LaunchStoreNode.java.
In this case, the configuration is provided at
http://localhost:9990/node-image/StoreNode by the domain manager. The
content of the file is basically an ATOM feed which contains the entries
of the deployable composite and a list of contributions:
<?xml version='1.0' encoding='UTF-8'?>
<feed xmlns="http://www.w3.org/2005/Atom";>
<title type="text">Install Image</title> <entry>
<id>composite:store;http://store;store</id> <!-- the QName of the
composite -->
<title type="text">store - http://store;store</title>
<content type="html" />
<link href="/composite-resolved/composite:store;http://store;store";
/>
<!-- The URL of the resolved composite file --> </entry>
<!-- The contributions -->
<entry>
<id>assets</id>
<title type="text">assets</title>
<content type="html" />
<link href="/contribution/assets" />
<link
href="file:/C:/Tuscany/java/sca/tutorial/domain/../assets/target/tutoria
l-assets.jar"
rel="alternate" />
</entry>
<entry>
<id>store</id>
<title type="text">store</title>
<content type="html" />
<link href="/contribution/store" />
<link
href="file:/C:/Tuscany/java/sca/tutorial/domain/../store/target/tutorial
-store.jar"
rel="alternate" />
</entry>
</feed>
Thanks,
Raymond
