Back in the olden days, much of our XML processing tools were inside the JDK. But ever since Java 9 and the migrations of Java EE-based packages to the Eclipse Foundation, those tools have since been pulled out of the JDK. On top of that, SOAP-based libraries, heavily leveraging the now Jakarta EE specs, have seen some upgrades.
This means you’ll be needing to either upgrade your plugins or switch to alternatives. For example, some SOAP apps use Jakarta XML Binding (JAXB). To comply with Jakarta EE 9+, you need JAXB 3.0. One way to access xjc, a popular tool to generate Java POJO classes from XSD files is shown below:
Example 1. Using JAXB’s xjc compiler on XSD files (airline/server/pom.xml)
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>xjc</id>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
<configuration>
<sources>${project.basedir}/src/main/resources/messages.xsd</sources>
<packageName>org.springframework.ws.samples.airline.schema</packageName>
<target>3.0</target>
</configuration>
</plugin>

This isn’t meant to be an extensive listing of all the settings, but instead one example of how to use it. Please visit the plugin’s ref docs for more details. |
There are several tools that will compile a WSDL into Java classes, one being Jakarta XML Web Services (JAX-WS).
Example 2. Using JAX-WS’s wsimport tool to compile a WSDL (airline/client/jax-ws/pom.xml)
<plugin>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
</execution>
</executions>
<configuration>
<!-- The name of your generated source package -->
<wsdlFiles>${project.basedir}/../airline.wsdl</wsdlFiles>
<packageName>org.springframework.ws.samples.airline.client.jaxws</packageName>
<sourceDestDir>${sourcesDir}</sourceDestDir>
<destDir>${classesDir}</destDir>
<extension>true</extension>
</configuration>
</plugin>
There are actually multiple ways to do this, and if you look at each sample, they each do things a little differently. Pick the one that meets your needs the best.
