Jsp Compliation problem in Weblogic 10.

Hi team,

We are migrating weblogic 8.1 to weblogic 10.0. We are facing some
exceptions in 10. We build aplication in Java 5, it is only the web-
application and the IDE is Sun Studio Creator 2 update 1 and we are
getting the below exception in run-time.

Home.jsp:19:57: Error in "/df/weblogic/dfuat100/servers/dfuat100-01/
tmp/_WL_user/InflightRetail/tgu6l9/war/pageheader.jspf" at line 1: The
encoding "null" specified in the XML prolog is unsupported.
<jsp:directive.include
file="pageheader.jspf"/>
