I have installed XML SQL utility for PL/SQL in Oracle 8.1.6.
when i am trying to get xml using xmlgen.getXML() method following error is thrown.

ORA-29532: Java call terminated by uncaught Java exception: java.util.MissingResourceException: can't find resource for oracle.xml.sql.mesg.XSUMessages_en_US

Is there any configuration problem with this?..
Thanks in advance
