Thank David H Nebinger!
But when I deploy it on Tomcat, 2 files portal-ext.properties and system-ext.properties are added in the $CATALINA_HOME/webapps/ROOT/WEB-INF/classes ...
And when I created an EXT via SDK ( ./create.sh ), It was generating a default portal-ext.properties file in the docroot/WEB-INF/ext-impl/src directory ... so I think they can be deployed via an EXT ... U can refer from page 58 - "liferay-developer-guide-6.0.pdf" - Creating an Ext plugin - or this
link...
Plz tell me why it is not available on Jboss 7.x? (I tried it on jboss 7.0.2 and 7.1.1 - and received a same result)...
