I 've added the multiple handler in the subsystem of urn:jboss:domain:webservices:1.2 in the standalone-full.xml.
XML extract of standalone-full.xml:
<subsystem xmlns="urn:jboss:domain:webservices:1.2">
<modify-wsdl-address>true</modify-wsdl-address>
<wsdl-host>${jboss.bind.address:127.0.0.1}</wsdl-host>
<endpoint-config name="Standard-Endpoint-Config"/>
<endpoint-config name="Recording-Endpoint-Config">
<post-handler-chain name="recording-handlers" protocol-bindings="##SOAP11_HTTP ##SOAP11_HTTP_MTOM ##SOAP12_HTTP ##SOAP12_HTTP_MTOM">
<handler name="RecordingHandler_1" class="org.jboss.ws.common.invocation.RecordingServerHandler"/>
<handler name="RecordingHandler_2" class="com.ServerHandler_1"/>
<handler name="RecordingHandler_3" class="com.ServerHandler_2"/>
</post-handler-chain>
</endpoint-config>
<client-config name="Standard-Client-Config"/>
</subsystem>
While starting the JBoss EAP 6.3 , getting the error in the console as "value already set for this injector error""
