Finding Description for Error Messages

Where can you find a description of what the error messge codes mean from 
WDSc for webfacing? 

I'm doing a web-facing project and some DDS that I converted before now 
has errors like: DDX0098 and the helpful text  ;-) after the just doesn't 
do it for me.  "Error with key sequence at node: SELPRJ = 
java.lang.NoSuchFieldError: 
Com/ibm/etools/iseries/dds/dom/annotation/WebSettingType.IBM_DISABLED_KEYS_LITERAL"

Now before that message I have have a DDX0040 "Function key lables 
detected and replaced with blanks".  But I've done nothing to the DDS 
since the first time I converted and don't remember having this.  The test 
using WDSc the screen comes up but is blank and the function keys are on 
the left side of the panel.  I'm sure  I've changed something in the "Re" 
conversion of  the DDS but don't know where to look from what error 
messages it is giving me.

Sorry for the cross post but not sure if this is a WDSc  or a  WEB400, 
question/problem/user error.

Thanks !!
