Source XML Error: External entity not found:

[Kaseman, Mark T]

        I just upgraded to orion 1.0.0.RC2 and when I try to generate an XML
document from my JSP code I receive the following error
Source XML Error: External entity not found:  xxxx.dtd. 
        This same code works fine under orion 1.0.0.RC1.
        Right now I am not sure what the problem/issue is ????
        Here is the beginning JSP code:

<?xml version="1.0"?>
<!DOCTYPE mtv-signon-grp PUBLIC "METAVANCE CICS REGIONS LIST"
"mtv-sign-on.dtd">
<?xml:stylesheet type="text/xsl" href="mtv-sign-on.xsl"?>

<jsp:useBean id="javaBeanSession"
class="com.mkaseman.util.JMTVCycle.EieJSPIntMTVSessionCheck" scope="page">
</jsp:useBean>
<jsp:useBean id="javaBeanAction"
class="com.mkaseman.util.JMTVCycle.EieJSPIntMTVRegionsList" scope="page">
</jsp:useBean>

        Here is the dtd definition:

<?xml version="1.0" encoding="UTF-8"?>
<!ELEMENT MTV-SIGNON-GRP        (MTV-SIGN-ON, LIST-OF-REGIONS+,
RETURN-INFO)>
<!ELEMENT MTV-SIGN-ON           (EDSNETID, EDSNETPwd, CICSRegion)>
<!ELEMENT LIST-OF-REGIONS       (REGION-ID+)>
