Hi guys!
I have a problem wen I run (trough a jsp page inside the package) a webapp
deployed in tomcat
********** This is the error log :

procesar la página JSP /taskclient.jsp en línea 26

"TaskListServiceComponent");
27: TaskList tl = taskListService.createTaskList(12, 22);
28: long listId = tl.getId();

As you can see it says that TaskListServiceComponent has not been
contributed to the domain.
******** This is the composite of my webapp:
<?xml version="1.0" encoding="UTF-8"?>
<sca:composite xmlns:sca="http://www.osoa.org/xmlns/sca/1.0";
name="Task" targetNamespace="http://eclipse.org/PlanningToolSCA/src/Task";>
<sca:component name="TaskListServiceComponent">
<sca:implementation.java class="main.task.lib.TaskListServiceImpl"/>
<sca:service name="TaskListService">
<sca:interface.java interface="main.task.api.TaskListService"/>
</sca:service>
<sca:reference name="taskCrudService"/>
</sca:component>
<sca:service name="TaskService"

</sca:service>
</sca:component>

This is the structure of the .war that I put in the tomcat webapps
folder ( I follow the calculator-ws-webapp example for this because I
want to use a ws binding in this way :
http://www.imageno.com/zckmhtxj3k0ipic.html )
WEB-INF
lib
classes
main
Task.composite
web.xml
geronimo
META-INF
taskclient.jsp
manifest.mf
That's about my execution problem, additionaly I have some doubts regards
the samples in the tuscany installation (and some general):
1. The files .composite defined in the samples don't use wires, since I
understand when you don't use wires is because you are using bindings for
communicating the components inside a composite. ¿Is that right? ¿Is there
any restriction for using wires when you run a contribution in Tomcat for
example?
2. ¿Is POJO the standard comunication mechanism in the tuscany
implementation when you use wires between components inside a Composite?
3. ¿Is there any example of many SCA Domains deployed as webapps in Tomcat
that use ws bindings (located as a service of the composite, when this
service is related trough a promotion of a component inside the composite)
that are communicating between them trough those bindings?
Your help will be apreciatted
