Link/Examples/MOXy/JPA. Créer et publier un Webservice avec Metro et Maven. Nous allons décrire ici la démarche à suivre pour publier un webservice dans tomcat avec Metro et maven. Tout d'abord initialiser le projet avec l’archétype webapp de maven : mvn archetype:create -DgroupId=com.test.ws.metro -DartifactId=metro-webapp -DarchetypeArtifactId=maven-archetype-webappcd . /metro-webappmvn clean Il n'y a pas de dépendances particulières à ajouter au pom.xml.
Nous utiliserons le même WSDL que dans l'exemple précédent utilisant CXF Placer le WSDL dans WEB-INF/wsdl/hello.wsdl A présent nous allons générer le code java grâce au plugin maven de Metro. Exécuter la commande suivante :mvn generate-sources Le code généré se trouve dans /target/generated/metro. Contrairement à CXF, ici, seules les interfaces ont été générées, il n'y a pas de skeleton. Créer le package ws.test.com.hello.impl dans /src/main/java et créer une classe (par exemple HelloImpl) héritant de l'interface générée Hello. Interface Hello générée : HelloImpl : Voilà pour l'implémentation. Un petit mvn package. Créer et publier un Webservice avec CXF et Maven. Nous allons voir dans ce billet comment créer et publier un service sur tomcat avec maven et CXF.Tout d'abord, initialiser le projet avec l'archetype webapp de Maven : mvn archetype:create -DgroupId=com.test.ws.cxf -DartifactId=cxf-webapp -DarchetypeArtifactId=maven-archetype-webapp cd .
/cxf-webapp mvn clean Editer le fichier pom.xml afin d'y rajouter les dépendances suivantes : <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>2.3.1</version> <artifactId>cxf-rt-transports-http</artifactId> Créer un WSDL, nous resterons classique et ferons un simple service HelloWorld : Placer le WSDL dans WEB-INF/wsdl/hello.wsdl A présent nous allons générer le code java grâce au plugin maven de CXF. Exécuter la commande suivante : mvn generate-sources Le code généré se trouve dans /target/generated/cxf. Il ne reste plus qu'a publier le service. <! Plus qu'a packager : mvn package Le war est prés à être déployé dans tomcat. have fun ;) Drop By! » Java Webservices – Relationship between JAX-WS, JAX-RS, Metro and Jersey. Have you ever wondered about the relationship of different actors within Java’s Webservice Stack?
I did. The key to the right answers you may find watching this list of Glassfish projects. So there seems to be a simple formula (RI = reference implementation): JAX-WS = JAVA-API( XML-based Webservices, means mainly WSDL/SOAP though REST is possible too ) RI(JAX-WS) = { javax.xml.ws.**.* , core Web services support } = JAX-WS “RI” [is subset of] Metro Metro = JAX-WS “RI” + WSIT/Tango ( WSIT/Tango provides support for Security, Reliability, Transactions and Interoperability with .NET 3.0 ) JAX-RS = JAVA-API( RESTful Web Services ) RI(JAX-RS) = { javax.ws.rs.**.* } = Jersey JAX-WS 2.1 along with JAXB 2.1 is integrated in JDK 6 Update 4 release as is JAX-WS in JDK 6.
JAX-RS is yet not finally released (see Schedule). If you are looking for the Metro libraries, either get them from GlassFish (webservices*.jar) , or download them from Metro distribution. Creating and Deploying JAX-WS web service on Tomcat 6. We Recommend These Resources Some years back I had to provide a wrapper around an EJB 3.0 remote service to come up with a simple web service project that would be deployed over Tomcat and accessed in a simple http way due to some accessibility issues.
Now as I cannot reveal the actual requirement I implemented that time so here I am presenting a simple demo kind of service with following signature. public AccountDetails getAccountDetails(String accountNo, SecurityToken token); The service will return the account details of a particular account number, provided the token is valid (generated using some Security module of the application). Libraries we are going to use include JAXB and JAX-WS, as both of them have sensible defaults, the number of annotations can be kept to the minimum.
Accounts.wsdl: To generate the artifacts , we run following command: wsimport C:\devel\workspace\webservice\WebContent\WEB-INF\wsdl\accounts.wsdl -p com.mg.ws -keep -Xnocompile <? Case: invalid security header. Deploy JAX-WS web services on Tomcat. Here’s a guide to show you how to deploy JAX-WS web services on Tomcat servlet container. See following summary steps of a web service deployment. Create a web service (of course).Create a sun-jaxws.xml, defines web service implementation class.Create a standard web.xml, defines WSServletContextListener, WSServlet and structure of a web project.Build tool to generate WAR file.Copy JAX-WS dependencies to “${Tomcat}/lib” folder.Copy WAR to “${Tomcat}/webapp” folder.Start It. Directory structure of this example, so that you know where to put your files. 1. A simple JAX-WS hello world example.
File : HelloWorld.java package com.mkyong.ws; import javax.jws.WebMethod;import javax.jws.WebService;import javax.jws.soap.SOAPBinding;import javax.jws.soap.SOAPBinding.Style; @WebService @SOAPBinding(style = Style.RPC)public interface HelloWorld{ @WebMethod String getHelloWorldAsString(); } File : HelloWorldImpl.java Later, you will deploy this hello world web service on Tomcat. 2. sun-jaxws.xml 3. web.xml <? Paul Downey :: Best Practice for Web Services. Best practices for Web services: Part 1, Back to the basics. Best practices for Web services versioning.
The correct handling of API versioning has been one of the most difficult issues faced by developers of distributed systems. Various schemes have been proposed, ranging from the laissez faire approach taken by CORBA to the stricter schemes used in DCOM. With the advent of Web services, there are some new features that you can take advantage of that can help alleviate the problem, but the brutal fact of the matter is that versioning has not been built into the Web services architecture.
Current products from IBM and other vendors do not directly address the versioning issue, requiring developers to solve the problem through the application of patterns and best practices. Understanding the Web services API versioning problem is easy. Imagine that we have a simple WSDL document that contains a WSDL operation defined using the fragment in Listing 1.
(This operation is derived from an example in the WSDL specification -- see Resources.) Listing 1. Listing 2. Back to top Listing 3. Figure 1.
