Environment
Release : Any
Component : Spectrum OneClick
Cause
Possible root cause are special characters in the Location Server hostname in the $SPECROOT/tomcat/webapps/spectrum/META-INF/context.xml file on the OneClick system.
Resolution
Examine the value of the "locServerName" parameter in the $SPECROOT/tomcat/webapps/spectrum/META-INF/context.xml file on the OneClick system for any special characters. For example:
locServerName="SpectrumMLS
"
If any are found than remove them so the value is the correct value of the MLS system and restart tomcat.
