Hyperjaxb and Apache CXF

问题:

I'm trying to use Hyperjaxb3 with Apache CXF to generate persistence annotations from a WSDL-first web service. I've plugged the Hyperjaxb3-ejb-plugin into the cxf-codegen-plugin, like so.

<plugin>
  <groupId>org.apache.cxf</groupId>
  <artifactId>cxf-codegen-plugin</artifactId>
  <version>${cxf.version}</version>
  <dependencies>
    <dependency>
      <groupId>org.jvnet.jaxb2_commons</groupId>
      <artifactId>jaxb2-basics</artifactId>
      <version>0.5.2</version>
    </dependency>
    <dependency>    
      <groupId>org.jvnet.hyperjaxb3</groupId>
      <artifactId>hyperjaxb3-ejb-plugin</artifactId>
      <version>0.5.4</version>
    </dependency>
  </dependencies> 
  <executions>
    <execution>     
      <id>generate-sources</id>
      <phase>generate-sources</phase>
      <configuration>
        <sourceRoot>${project.build.directory}/generated/cxf</sourceRoot>
        <wsdlOptions>
          <wsdlOption>
            <wsdl>${basedir}/src/main/resources/wsdl/CDXLEAToCourt.wsdl</wsdl>
            <xjcargs>
              <xjcarg>-Xequals</xjcarg>
              <xjcarg>-XtoString</xjcarg>
              <xjcarg>-Xhyperjaxb3-ejb</xjcarg>
            </xjcargs>
          </wsdlOption>
        </wsdlOptions>
      </configuration>
      <goals>
        <goal>wsdl2java</goal>
      </goals>
    </execution>
  </executions>
</plugin>

When I generate source, I get the following informative stack trace.

Failed to execute goal org.apache.cxf:cxf-codegen-plugin:2.2.7:wsdl2java (generate-sources) on project leaToCourtWS: Failed to generate types. -> [Help 1]

I've been banging my head against this for a while. I tried to continue the project without Hyperjaxb, but don't want to incur the maintenance costs. Any ideas? A solution to the exception- or an alternative to using Hyperjaxb- would be great.

回答1:

Found a solution. I emailed Aleksei - the project owner- and he informed me that Hyperjaxb3 CXF integration was introduced in .5.5, which has yet to be released. D'oh!

He suggested I use the snapshot repository. I added the repository to my POM, changed the version of the hyperjaxb3-ejb-plugin to 0.5.5-SNAPSHOT- and so far, everything works beautifully.

回答2:

It seems the problem comes from your WSDL file.

There is a working example within the source code of Hyperjaxb3 called customerservice-cxf that might help you.
