Hi Ana Belen
I took your classes, cut them down a little bit and gave it a spin. I listed
the files I ended up with below. Running isClient.java gives.
Buildfile: build.xml
run-classes:
[java] Starting ...
[java] Information.composite ready
[java] String: a string
BUILD SUCCESSFUL
Can you see if you can get running with these files. If you still have
problems then its likely to be some environment issue. From your fist post
it looks like you are running against the 1.0 distribution. I created a
simple sample project (by copying the calculator sample) to run this with
the 1.0 distribution. This is the ant target I used is.
<property name="test.class" value="Client.isClient" />
<target name="run-classes">
<java classname="${test.class}"
fork="true">
<classpath>
<pathelement path="target/classes"/>
<pathelement location="../../lib/tuscany-sca-manifest.jar"/>
</classpath>
</java>
</target>

Information.composite (This is the same as your copy)
========================================
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
name="InformationComposite">
<component name="InformationServiceComponent">
<implementation.java class="
eu.services.information.rh.InformationServiceImpl"/>
</component>
</composite>
InformationService.java
=================
package eu.services.information.is;
import org.osoa.sca.annotations.Remotable;
import eu.services.information.exceptions.*;
import eu.services.information.io.InformationObject;
@Remotable
public interface InformationService {
public InformationObject getInformationObject (String id)
throws ISNotFoundException;
}
InformationServiceImpl.java
====================
package eu.services.information.rh;
import org.osoa.sca.annotations.Service;
import eu.services.information.exceptions.*;
import eu.services.information.io.InformationObject;
import eu.services.information.is.*;
@Service(InformationService.class)
public class InformationServiceImpl implements InformationService{
//----------------------------------------------------------------------------------------------------------
public InformationObject getInformationObject(String id) throws
ISNotFoundException{
InformationObject io = new InformationObjectImpl();
//code
return io;
}
}
InformationObject.java (I just made this up:-)
===============================
package eu.services.information.io;
public interface InformationObject {
public String getText();
}
InformationObjectImpl.java
===================
package eu.services.information.rh;
import java.io.Serializable;
import eu.services.information.io.InformationObject;
public class InformationObjectImpl implements InformationObject,
Serializable {
public String getText(){
return "a string";
}
}
isClient.java
=========
package Client;
import org.apache.tuscany.sca.host.embedded.SCADomain;
import eu.services.information.exceptions.ISNotFoundException;
import eu.services.information.io.InformationObject;
import eu.services.information.is.InformationService;

public static void main(String[] args) throws Exception {
System.out.println("Starting ...");
SCADomain scaDomain = SCADomain.newInstance("Information.composite");
System.out.println("Information.composite ready");
InformationService is = scaDomain.getService(InformationService.class,
"InformationServiceComponent");
InformationObject iobj;
try {
iobj = is.getInformationObject("c1dee5cd");
System.out.println("String: " + iobj.getText());
} catch (ISNotFoundException e1) {
e1.printStackTrace();
}
scaDomain.close();
}
}
