So, I have stumbled on this error too, and it really got on my nerves. So, without further due
environment:
Wildfly 20.0.1.Final
Java 11
objectives:
I just want to add cxf so that I could use cxf - spring descriptors (in particular jaxws:endpoint) in my applicationContext.xml, i.e
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<!-- one or more jaxws:endpoint POJO declarations -->
<jaxws:endpoint id="POJOEndpoint" address="/test" implementor="com.test.myRandomPojoEndpoint">
<jaxws:invoker>
<bean class="org.jboss.wsf.stack.cxf.InvokerJSE"/>
</jaxws:invoker>
</jaxws:endpoint>
</beans>
issue:
but all I get is
Invalid NamespaceHandler class
[org.apache.cxf.jaxws.spring.NamespaceHandler] for namespace
[http://cxf.apache.org/jaxws]: problem with handler class file or
dependent class; nested exception is java.lang.NoClassDefFoundError:
org/springframework/beans/factory/xml/NamespaceHandlerSupport
Solution:
before you begin you SHOULD KNOW that for this stuff to work you have to INSTALL SPRING LIBRARIES to your wildfly application server and so...
The list of spring libraries in my wildfly environment:
spring-aop-5.2.9.RELEASE.jar
spring-beans-5.2.9.RELEASE.jar
spring-context-5.2.9.RELEASE.jar
spring-core-5.2.9.RELEASE.jar
spring-expression-5.2.9.RELEASE.jar
spring-jcl-5.2.9.RELEASE.jar
spring-tx-5.2.9.RELEASE.jar
spring-web-5.2.9.RELEASE.jar
Installation path is as follows
wildfly-20.0.1.Final\modules\system\layers\base\org\springframework\spring\main
just put spring libraries in this path and add module.txt (that same folder as spring libraries) as follows
module.txt
<?xml version="1.0" encoding="UTF-8"?>

======THE END==========
NOTES:
So, if that is so simple why did I fail? WHY?
At first I installed spring libraries in
wildfly-20.0.1.Final\modules\system\layers\base\org\spring\main
and that cause a lot of misery, because
if you looked at
wildfly-20.0.1.Final\modules\system\layers\base\org\apache\cxf\impl\main\module.xml, you would see that it has a dependency on spring, i.e
<module name="org.springframework.spring" optional="true">
<imports>
<include path="META-INF"/>
</imports>
</module>
however, I installed spring libraries under different name which was org.spring and not org.springframework.spring, so that was the root of my failure.
my jboss-deployment-structure.xml (in WEB-INF folder) is
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="org.springframework.spring">
<imports>
<include path="META-INF"/>
</imports>
<exports>
<include path="META-INF"/>
</exports>
</module>
<module name="org.apache.cxf">
<imports>
<include path="META-INF/cxf"/>
<include path="META-INF"/>
</imports>
<exports>
<include path="META-INF/cxf"/>
<include path="META-INF"/>
</exports>
</module>
<module name="org.apache.cxf.impl">
<imports>
<include path="META-INF/cxf"/>
<include path="META-INF"/>

<exports>
<include path="META-INF/cxf"/>
