WSDL First Demo =============== This demo shows how to build and call a webservice using a given WSDL (also called Contract First). As writing a WSDL by hand is not so easy the following How-To may be a useful read: http://cxf.apache.org/docs/defining-contract-first-webservices-with-wsdl-generation-from-java.html This demo mainly addresses SOAP over HTTP in Document/Literal or Document/Literal wrapped style. For other transports or styles the configuration may look different. The Demo consist of three parts: - Creating the server and client code stubs from the WSDL - Service implementation (using JAX-WS or using Spring) - Client implementation (using JAX-WS or using Spring) Code generation --------------- When using Maven the code generation is done using the Maven cxf-codegen-plugin (http://cxf.apache.org/docs/maven-cxf-codegen-plugin-wsdl-to-java.html). The code generation is tuned using a binding.xml file. In this case the file configures normal Java Dates to be used for xsd:date and xsd:DateTime. If this is not present then XMLGregorianCalendar will be used. One other common use of the binding file is to also generate asynchronous stubs. The line jaxws:enableAsyncMapping has to be uncommented to use this. More info about the binding file can be found here: http://jax-ws.java.net/jax-ws-20-fcs/docs/customizations.html Server implementation --------------------- The service is implemented in the class CustomerServiceImpl. The class simply implements the previously generated service interface. The method getCustomersByName demonstrates what a query function could look like. The idea is to search and return all customers with a given name. If the searched name is none then the method returns an exception to indicate that no matching customer was found. (In a real implementation a list with zero objects would probably be used. This is mainly to show how custom exceptions can be created). For any other name the method will return a list of two Customer objects. The number of objects can be increased to test how fast CXF works for larger data. Now that the service is implemented it needs to be made available. This sample provides two options for deploying the web service provider: standalone server (using embedded Jetty) or as a WAR file in Tomcat (Version 6.x or 7.x). Client implementation --------------------- The main client code lives in the class CustomerServiceTester. This class needs a proxy to the service and then demonstrates some calls and their expected outcome using junit assertions. The first call is a request getCustomersByName for all customers with name "Smith". The result is then checked. Then the same method is called with the invalid name "None". In this case a NoSuchCustomerException is expected. The third call shows that the one way method updateCustomer will return instantly even if the service needs some time to process the request. The classes CustomerServiceClient and CustomerServiceSpringClient show how to get a service proxy using JAX-WS or Spring and how to wire it to your business class (in this case CustomerServiceTester). Prerequisite ------------ Please review the README in the samples main directory before continuing. Building and running the demo using Maven ----------------------------------------- From the base directory of this sample (i.e., where this README file is located), the pom.xml file is used to build and run the demo. Using either UNIX or Windows: mvn clean install (builds the demo and creates a WAR file for optional Tomcat deployment) mvn -Pserver (from one command line window -- only if using embedded Jetty) mvn -Pclient (from a second command line window) There is no special Maven profile for the Spring client and server but you can easily set it up yourself. If you're using Tomcat (embedded or standalone) for the web service provider: ---------------------------------------------------- 1.) Update the soap:address value in the resources/CustomerService.wsdl value, switching the soap:address value to the servlet-specific one (presently commented-out). 2.) For standalone Tomcat: You can manually copy the generated WAR file to the Tomcat webapps folder, or, if you have Maven and Tomcat set up to use the Tomcat Maven Plugin (http://tomcat.apache.org/maven-plugin-2.1/tomcat7-maven-plugin/index.html) you can use the mvn tomcat7:redeploy command instead. For embedded Tomcat: Just run mvn tomcat7:run-war from the project base folder. 3.) Next activate the client via mvn -Pclient as explained in the previous section. To remove the code generated from the WSDL file and the .class files, run "mvn clean". Using Eclipse to run and test the demo -------------------------------------- Run the following in the demo base directory mvn eclipse:eclipse Then use Import / Existing projects into workspace and browse to the wsdl_first directory. Import the wsdl_first project. The demo can now be started using "Run as Java Application" on the CustomerServiceServer.java and the CustomerServiceClient. For the spring demo run the classes CustomerServiceSpringClient.java or CustomerServiceSpringServer.java
