Indeed, SCA Tools do not yet support Tuscany 2.x.
I can take a moment (probably tomorrow) to integrate this support.
As we do not plan an intermediate release for the moment, and if you are
interested, I can then explain you how to proceed to use this update
without reinstalling SCA Tools.

Regards,

Vincent Zurczak.

Help

cant get tuscany and gallileo STP to work for tuscany 1.5 or tuscany v2
M3, and 1.6.13 java vm

forgive me guys - newbie here

I've downloaded gallileo, and enabled the STP tools etc version 2.0.0.2009

ive downloaded tuscany 1.5 and version 2M3 and installed on my C drive.

i've created two projects in eclipse one for version 1.5 libraries and
another for version 2 libraries.

wanted to do something real simple start so i created two user libraries
in eclipse
tuscany v1 libs - pointed at tuscany 1.5\lib\tuscany_sca_all.jar

and

tuscany v2 libs - pointed at tuscany v2m3/modules/*.jar (cant find a /libs
directory at all - is that expected??)

created two proejcts for "hello world" newbie build.

essentially I have a java interface (mared @Remotable) and a java
implementation class marked with @Service (HelloWorld.class)

I then create the composite in the diagram editor as follows

<?xml version="1.0" encoding="UTF-8"?>
<sca:composite xmlns:sawsdl="http://www.w3.org/ns/sawsdl"
xmlns:sca="http://www.osoa.org/xmlns/sca/1.0" name="demoSCA"
targetNamespace="http://eclipse.org/demoSCA/demoSCA">
<sca:component name="HelloWorldComponent">
<sca:implementation.java class="HelloWorldImpl"/>
<sca:service name="helloWorld">
<sca:interface.java interface="HelloWorld"/>
<sawsdl:semantic.sawsdl/>
</sca:service>
<sawsdl:semantic.sawsdl/>
</sca:component>
<sca:service name="helloWorld" promote="HelloWorldComponent/helloWorld">
<sca:interface.java interface="HelloWorld"/>
</sca:service>
</sca:composite>

I then build a standalone client to service

my version 1 client looks like this

//demoV1SCA.java
import org.apache.tuscany.sca.host.embedded.SCADomain;

public class demoV1Main
{

/**
* @param args
*/
public static void main(String[] args)
{
// TODO Auto-generated method stub

//create new Tuscany node

System.out.println("starting new domain\n");

// Locate the service using SCA APIs
SCADomain domain = SCADomain.newInstance("demoSCA");

System.out.println("lookup service\n");
HelloWorld hello = domain.getService(HelloWorld.class, "HelloWorld");

// Calculate
System.out.println("say " + hello.helloWorld());
try
{
System.in.read();
} catch (Exception e)
{
System.exit(0);
}

SCADomain.removeInstance(domain);
}

}

This errors with the following if i try and run the class in eclipse

as follows

tarting new domain

however under version two i cant find an SCADomain class at all . looked
and google and came up with this.

//demoV2SCA.java
import org.apache.tuscany.sca.node.Client;
import org.apache.tuscany.sca.node.Node;
import org.apache.tuscany.sca.node.NodeFactory;

public class demoV2Main
{

/**
* @param args
*/
public static void main(String[] args)
{
// TODO Auto-generated method stub

//create new Tuscany node

NodeFactory nf = NodeFactory.newInstance();

//String root =
ContributionLocationHelper.getContributionLocation("HelloWorld ");
//Contribution contribution = new Contribution(root, root);

Node node = nf.createNode();

System.out.println("start tuscany node \n");
node.start();

HelloWorld hello = ((Client)node).getService(HelloWorld.class,
"HelloWorld");

// Calculate
System.out.println("say " + hello.helloWorld());
try
{
System.in.read();
} catch (Exception e)
{
System.exit(0);
}

node.stop();
}

}

which errors with

Exception in thread "main" org.oasisopen.sca.ServiceRuntimeException: No
SCA contributions are found on the classpath
at
org.apache.tuscany.sca.node.NodeFactory.createNode(NodeFacto ry.java:367)
at demoV2Main.main(demoV2Main.java:25)

Can anyone please help to get a basic version in 1.5 or v2 up and running
What am i doing wrong ?!!

Hi Amit,

This error may occur in two cases:

+ You are using Tuscany 1.x but you did not specify the runtime
librairies location in the SCA preference page. To solve it, go in your
preference page and create / update the Tuscany configuration.

+ You are using Tuscany 2.x.
This case has not yet been fixed.
I have everything I need to fix it, except time. :(
Besides, with the Tuscany 2.x, all the librairies are not in the same
directory, and it is really painful to use the current deployment mechanism.

I have to adapt the way we reference runtime location, and this is what
takes most of the time. Anyway, this is expected for December, as
desxcribed on our roadmap [0]. But I think it will be solved before.

Just be patient. ;)
The best solution, waiting for this, is to create your own launcher for
Tuscany 2.x. A sample is available here [0].

Regards,

Vincent.
