Hi Simon, I have used target servlet as Tuscany servlet which is actually get some URI path from me and get me some servlet, But if u see the complete Process of How it get URI from us and get servlet back to us it looks there is one map in WebAppServletHost called servles it is the creating problem for me, You can download source code of Tuscany from http://cwiki.apache.org/TUSCANY/sca-java-releases.html Mine problem now is How to register servlet and call one function addServletMapping() from WebAppServletHost.java file thanks Nishant Joshi This message and the information contained herein is proprietary and confidential and subject to the Amdocs policy statement, you may review at http://www.amdocs.com/email_disclaimer.asp
Ok, I think we need to take a step back and walk through what you are trying to do. From the previous posts I have imagined that you were trying to 1/ run SCA as part of a web app (and that you have got that working) 2/ add some web services to that web app Let me know if you are trying to do something else. Assuming this is the case lets talk about 1/ first. There is an example of how to do this in samples/calculator-webapp. If you look at the Calculator.composite file for this application you see <composite xmlns="http://www.osoa.org/xmlns/sca/1.0"; targetNamespace=" http://sample"; xmlns:sample="http://sample"; name="Calculator"> <component name="CalculatorServiceComponent"> <implementation.java class="calculator.CalculatorServiceImpl"/> <reference name="addService" target="AddServiceComponent"></reference> <reference name="subtractService" target="SubtractServiceComponent"></reference> <reference name="multiplyService" target="MultiplyServiceComponent"></reference> <reference name="divideService" target="DivideServiceComponent"></reference> </component> <component name="AddServiceComponent"> <implementation.java class="calculator.AddServiceImpl"/> </component> <component name="SubtractServiceComponent"> <implementation.java class="calculator.SubtractServiceImpl"/> </component> <component name="MultiplyServiceComponent"> <implementation.java class="calculator.MultiplyServiceImpl"/> </component> <component name="DivideServiceComponent"> <implementation.java class="calculator.DivideServiceImpl "/> </component> </composite> Now there is no mention here of servlets or that this application is running in a webapp. If you look at the calculator-webapp\src\main\webapp\calc.jsp file you see <%@ page import="org.apache.tuscany.sca.host.embedded.SCADomain"%> <%@ page import="calculator.CalculatorService" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <% SCADomain scaDomain = (SCADomain) application.getAttribute(" org.apache.tuscany.sca.SCADomain"); CalculatorService calculatorService = scaDomain.getService( CalculatorService.class, "CalculatorServiceComponent"); %> <html> <head><title>Calculator sample</title></head> <body> <table> <tr> <th>Expression</th><th>Result</th> </tr> <tr> <td>2 + 3</td><td><%= calculatorService.add(2, 3) %></td> </tr> <tr> <td>3 - 2</td><td><%= calculatorService.subtract(3, 2) %></td> </tr> <tr> <td>3 * 2</td><td><%= calculatorService.multiply(3, 2) %></td> </tr> <tr> <td>3 / 2</td><td><%= calculatorService.divide(3, 2) %></td> </tr> </table> </body> </html> The web.xml file itself uses the TuscanyContextListener to start the SCA runtime (SCADomain) and register it in the servlet context so that the JSP can access it. <web-app> <display-name>Tuscany Calculator Web Service Sample</display-name> <listener> <listener-class>org.apache.tuscany.sca.webapp.TuscanyContextListener</listener-class> </listener> <welcome-file-list id="WelcomeFileList"> <welcome-file>calc.jsp</welcome-file> </welcome-file-list> </web-app> In case 2/. If you want to expose some of the SCA components as web services then you need to describe the appropriate bindings in the composite file, for example, here, I have changed the calculator SCA application to expose the AddServiceComponent as a web service. I have to provide the WSDL for this service but the runtime should be able to work out how to register the underlying Axis servlet so that the web services run. <composite xmlns="http://www.osoa.org/xmlns/sca/1.0"; targetNamespace="http://sample"; xmlns:sample=" http://sample"; name="Calculator"> <component name="CalculatorServiceComponent"> <implementation.java class="calculator.CalculatorServiceImpl "/> <reference name="addService" > <interface.java interface="calculator.AddService" /> <binding.ws wsdlElement=" http://calculator#wsdl.port(AddService/AddSoapPort)<http://calculator#wsdl.port%28AddService/AddSoapPort%29>"/> </reference> <reference name="subtractService" target="SubtractServiceComponent"></reference> <reference name="multiplyService" target="MultiplyServiceComponent"></reference> <reference name="divideService" target="DivideServiceComponent"></reference> </component> <component name="AddServiceComponent"> <implementation.java class="calculator.AddServiceImpl"/> <service name="AddService"> <interface.java interface="calculator.AddService" /> <binding.ws wsdlElement="http://calculator#wsdl.port(AddService/AddSoapPort)<http://calculator#wsdl.port%28AddService/AddSoapPort%29> "/> </service> </component> <component name="SubtractServiceComponent"> <implementation.java class="calculator.SubtractServiceImpl"/> </component> <component name="MultiplyServiceComponent"> <implementation.java class="calculator.MultiplyServiceImpl "/> </component> <component name="DivideServiceComponent"> <implementation.java class="calculator.DivideServiceImpl"/> </component> <component name="ExtensionPointRegistryInspectorComponent"> <implementation.java class=" org.apache.tuscany.sca.tools.registryinspector.inspector.ExtensionPointRegistryInspectorImpl"/> </component> </composite> I'm in the middle of trying this out to make sure that it does run :-). Let me know if these two points are an accurate reflection of what you are trying to achieve. In particular I'm interested to know why you ask " How to register servlet and call one function addServletMapping() from WebAppServletHost.java file" as this function should be hidden unless of course you are writing some new host integration.
