!/META-INF/ejb-jar.xml process fatal error. Line: 4. Error message: The processi
ng instruction target matching "[xX][mM][lL]" is not allowed.

my deployment descriptor is as following.


<!DOCTYPE ejb-jar PUBLIC
"-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN"
 "http://java.sun.com/dtd/ejb-jar_2_0.dtd">

Thanks in advance...

The XML declaration must be at the beginning of an XML file:
