To do a POC, I have a wrote a JAXWS class in the same package used for AXIS-2 services and configured that class in web.xml (content pasted below)

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

Please help me on this. Is this because of running both AXIS and JAXWS in the same app ? or is there any configuration to overcome this ??

Regards
Arun

Atlast found why 🙂

First of all both axis & JAXWS cannot run inside the same application
Axis’s SAAJ jar will load and will allow only its soap-factory to load and
not jaxws’s soap factory

So I took all the axis references in my project and removed axis-saaj jar. Now it started working 🙂
