Error when trying to use a hello word webservice : ClassNotFoundException: org.apache.axis2.databinding.ADBException

Question

I have an error since 2-3 days from now so I have an axis2 project and I'm trying to use the following webservice on the server side :

HelloService.java

public class HelloService {

public String sayHelloWorldFrom(String from) {
    String result = "Hello, world, from " + from;
    System.out.println(result);
    return result;
    }
}

Here is the wsdl that I've generated :

    </wsdl:port>
</wsdl:service>

But when I'm trying to use the hello world service from client side, I have the following error :

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/axis2/databinding/ADBException
at org.hello.HelloService.main(HelloService.java:10)
Caused by: java.lang.ClassNotFoundException: org.apache.axis2.databinding.ADBException
at java.net.URLClassLoader.findClass(URLClassLoader.java:382)

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:355)
at java.lang.ClassLoader.loadClass(ClassLoader.java:351)
... 1 more

Process finished with exit code 1

So as you can see in the HelloService.java, I don't use the jaw-xs annotations because Tomcat server doesn't identify the annotations

Thanks for your help.

//Edit : 05/05/2020 I'm using maven and the axis2 jars are already added in the module :

• Server
• Client

Answer 1

Some dependencies are defined with Provided scope which is not automatically added in runtime.

The solution is to either change the scope of the dependencies in pom.xml or change the Run/Debug configuration to include the dependencies with the provided scope in runtime.
