java - Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

Question

I have hard times using maven to generate my web service client. So please refer to Creating a web-service client directly from the source for the first part of my question.

To keep it simple and short, I want to go from here (a file in src/main/java) :

package com.example.maven.jaxws.helloservice;
   
import javax.jws.WebService;

@WebService
public class Hello {
     public String sayHello(String param) {
         return "Hello " + param;
     }
} 

to there :

/**
 * This class was generated by the JAX-WS RI.
 * JAX-WS RI 2.1.7-b01-
 * Generated source version: 2.1
 * 
 */
@WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/")
public class HelloService extends Service {

    private final static URL HELLOSERVICE_WSDL_LOCATION;
    private final static Logger logger = 
         Logger.getLogger(com.example.wsimport.HelloService.class.getName());
    ...etc

using only 1 pom.xml file.

Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

Assuming, you're not going to try to use the generated stubs in the same project that you're doing this in (which would create circular dependencies and be a bad idea...) then, yes, you can do something like this.

The config is not all that tricky, in fact you'd kind of guessed it in your question but here goes:

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxws-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>generate-wsdl</id>
                    <phase>process-classes</phase>
                    <goals>
                        <goal>wsgen</goal>
                    </goals>
                    <configuration>
                        <sei><!-- fully qualified class name goes here --></sei>
                        <genWsdl>true</genWsdl>
                    </configuration>
                </execution>
                <execution>
                    <id>generate-stubs</id>
                    <phase>process-classes</phase>
                    <goals>
                        <goal>wsimport</goal>
                    </goals>
                    <configuration>
                        <wsdlDirectory>target/jaxws/wsgen/wsdl</wsdlDirectory>
                        <wsdlFiles>                   
                            <wsdlFile><!-- class name goes here -->Service.wsdl</wsdlFile>
                        </wsdlFiles>
                        <!-- *** you need the next line to set the wsdlLocation in the generated stubs *** -->
                        <wsdlLocation>http://localhost:8080/test</wsdlLocation> 
                    </configuration>
                </execution>
            </executions>
        </plugin>

Update - to package up the generated code into a jar I would use the maven-jar-plugin like so:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <executions>
                    <execution>
                        <id>package-wsclient-jars</id>
                        <phase>package</phase>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                        <configuration>
                            <classesDirectory>target/jaxws/<!-- rest of the path here, can't remember it right now --></classesDirectory>
                            <classifier>wsclient</classifier>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

I've quickly pasted this from our config but our usage is a little different (as we zip up the wsdl files not the generated client but I believe this will get you pretty close). You'll probably have to setup the version for the maven-jar-plugin if you're not already using it - 2.3.1 seems to be the latest.
