Axis 2 with maven

[Trilochan Bharadwaj]

Hi,

I am new to Web services and was trying axis2, Here's a summary of steps i followed:
***********************************************************************
1.) Create a maven project using mvn archetype:generate, use option 36 which was simply myfaces project.
2.) Added following entry :

<groupId>org.apache.axis2</groupId>
				      <artifactId>axis2-java2wsdl-maven-plugin</artifactId>
                  		       <version>1.4.1</version>

on plugins element of POM xml.
3.) Create a simple class OMNamahShivayaWebService that has a method praise that passes in a deity name as string and returns a string with praise (OM Namah + deity name) ;)
4.) Added in plugin section (within axis2-java2wsdl-maven-plugin entry) following:

 <configuration>
					<className>om.shiva.OMNamahShivayaWebService</className>
				</configuration>   

5.) ran command mvn clean axis2-java2wsdl:java2wsdl -e and got this exception (stack trace) :

Any ideas as to what I should be doing or am I missing something? I just want to deploy this service.
