  • It seems that JVM cannot find OMNode class. Is OMNode library is set in the class path on the server? Do you have the OMNode jar file? Check out https://ws.apache.org/axiom/userguide/ch02.html "Once the Axiom binary is obtained by any of the above ways, it should be included in the classpath for any of the Axiom based programs to work. Subsequent sections of this guide assume that this build step is complete and axiom-api-1.2.19.jar and axiom-impl-1.2.19.jar are present in the classpath along with the StAX API jar file and a StAX implementation." – Yan Jul 26 '16 at 04:01

The apache axiom library is not in your classpath. If you use maven, make sure that it is in your pom.xml. if it's there, make sure that it has the runtime scope: <scope>runtime</scope>.

An easy way to make this class available to your web application is to put the axiom.jar file in your WEB-INF/lib folder.

Add below dependency to your project. (Change version as you want)
