 Please read https://rsjazz.wordpress.com/2013/12/02/beware-of-the-underscore/ carefully. Underscore is not a legal character for a host name.

Thanks Ralph.

As per the wiki link in your blog (http://en.wikipedia.org/wiki/Hostname#Restrictions_on_valid_host_names), it says "While a hostname may not contain other characters, such as the underscore character (_), other DNS names may contain the underscore"

My CLM URI is "https://XXXX.xyz_01.com:9443" but when I am trying to login in to the setup I am not able to login. On checking the logs I found below in Systemout.log and jts.log

E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[equinoxbridgeservlet]: java.lang.RuntimeException: Failed to generate URI from incoming request data

Caused by: java.net.URISyntaxException: Illegal character in hostname at index 29: "https://XXXX.xyz_01.com:9443"
+++++++++++

Is the above issue because of underscore in URL? Is there any workaround as we cann't change the domain name itself.

The problem seems to be that the Java.net code chokes on the underscore. So as far as I can tell, the underscore is not tolerated by this Java version.
