I want to create a SOAP Web Service. I am using JDK 17, Axis2 1.8.2, Tomcat 10.1, Eclips (2024-03).

I want to implement some endpoints to call with SOAP UI or other client.

Issues:
After creating the web service and run on server (tomcat 10.1) gives me HTTP Status 500 – Internal Server Error.

Full error:

HTTP Status 500 – Internal Server Error
Type Exception Report

Message Error instantiating servlet class [org.apache.axis2.transport.http.AxisServlet]

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Any help or guidance would be greatly appreciated.
Thank you!

Tried:

1. Creting endpoints or call back methods.

Expected:

1. Can call those endpoint via API tools(Postman, SOAP UI).

Resulted:

1. HTTP Status 500 – Internal Server Error.
