无法从wsdl文件生成Java代码

Question

First I created simple web service with java and then generated wsdl for that web service and tested with SoapUI so it works fine. After that now I am tring to generate java classes from wsdl file which was generated previously.

Here is the my pom.xml file configuration.

            </plugin>
        </plugins>

        </build>


    </project>

When I tried to generate it I am getting error like this.

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project contractFirst: Compilation failure: Compilation failure:

    [ERROR] /home/contractFirst/target/generated/src/main/java/demo/order/ProcessOrder.java:[28,1] error: annotations are not supported in -source 1.3
    [ERROR] 

So I dont understed what is this - source 5 thing is ?

Update :According to @Simze's answer above error is disappeared. Now I am geeting this error.

wsdl file

Answer 1

Finally found the solution for this. When we are generating java code for given wsdl file we need to specify what are to be generated in the configuration section of cxf-codegen-plugin

...
   <wsdlOptions>
    <wsdlOption>
        <wsdl>${basedir}/src/main/resources/OrderProcess.wsdl</wsdl>
        <extraargs>
            <extrrg>-impl</extrrg>
            <extrrg>-server</extrrg>
        </extraargs>
    </wsdlOption>
    </wsdlOptions>
 .....

Here -impl means this will generate the service implementation class and -server is used to generate server component which can be used to publich the service.

Answer 2

The error you're getting because, you're trying to run maven under Java 1.3, which doesn't support annotations. Please add below tags under <build> element which will solve your problem.

<plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.0</version>
      <configuration>
        <source>1.7</source>
        <target>1.7</target>
      </configuration>
    </plugin>
</plugins>

Answer 3

You need to use Java 1.5 or higher. This is what the compiler error is telling you when it says - source 5 thing because annotation support was added to Java from Java 1.5 onwards.
