Reading the http://wiki.jboss.org/wiki/Wiki.jsp?page=ExplodedDeployment page, it seems that suffixing an exploded directory with ".war" is mandatory. Ok for that point. But still, I do no understand why when I'm trying to map a servlet plus a JSP it doesn't work on my JBoss instance, while the same file with only the JSP indicated works... The "web.xml" which works : <?xml version="1.0"?> | <web-app version="2.4" | xmlns="http://java.sun.com/xml/ns/j2ee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> | <servlet> | <servlet-name>ClientTest</servlet-name> | <jsp-file>/client.jsp</jsp-file> | </servlet> | </web-app> The one which doesn't work... : <?xml version="1.0"?> | <web-app version="2.4" | xmlns="http://java.sun.com/xml/ns/j2ee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> | <servlet> | <servlet-name>ClientTest</servlet-name> | <jsp-file>/client.jsp</jsp-file> | </servlet> | <servlet> | <servlet-name>ControlerServlet</servlet-name> | <servlet-class>com.mydomain.myappli.common.ControlerServlet</servlet-class> | </servlet> | </web-app> Regards View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979110#...
