The following exception is reported when deploying an endpoint to a server bound to an IPv6 address: -

Caused by: org.jboss.ws.WSException: Malformed URL: http://3ffe:ffff:100:f101::1:8080/admindevel
at org.jboss.ws.metadata.builder.MetaDataBuilder.getServiceEndpointAddress(MetaDataBuilder.java:272)

The address part needs to be wrapped in square brackets to make it correct in the URL e.g.: -

http://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]:80/index.html
http://[1080:0:0:0:8:800:200C:417A]/index.html
