About this task

Within Eclipse:

Procedure

  1. Create a Maven project, following the same steps as in this section, and call it locator_common for the purposes of this example.
  2. Remove all default sources, as well as test source folder.
  3. Create a package named demo.common, and create an interface Greeter.java:
    package demo.common;
    
    import javax.jws.WebService;
    
    @WebService(targetNamespace = "http://talend.org/esb/examples/", 
            name = "Greeter")
    public interface Greeter {
        String greetMe(String requestType);
    }
    Greeter.java will be the service interface. The project structure will look like this:

    Example

  4. The common application will be deployed as an OSGi bundle. You will need to edit the pom.xml file.
    <project xmlns="http://maven.apache.org/POM/4.0.0" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
                            http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.talend.liugang.cxf</groupId>
        <artifactId>locator_common</artifactId>

        <packaging>bundle</packaging>

        <dependencies>
            <dependency>
                <groupId>org.apache.felix</groupId>
                <artifactId>org.osgi.core</artifactId>
                <version>1.4.0</version>
            </dependency>
        </dependencies>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.felix</groupId>
                    <artifactId>maven-bundle-plugin</artifactId>
                    <extensions>true</extensions>
                    <version>2.3.7</version>
                    <configuration>
                        <instructions>
                            <Bundle-SymbolicName>
                                ${project.artifactId}
                            </Bundle-SymbolicName>
                            <Export-Package>
                                demo.common
                            </Export-Package>
                        </instructions>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </project>
    
  5. Now that you have finished the definition of the service, select Run As > Maven Install from the M2Eclipse Popup menu on the pom.xml to install the application into your Maven repository.
    The next step is to implement this service.
