I think that has something to do with web.xml descriptor.
Contents of web.xml:
| <?xml version="1.0" encoding="ISO-8859-1"?>
|
| <!DOCTYPE web-app
| PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
| "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
|
| <web-app>
| <servlet>
| <servlet-name>XXXServlet</servlet-name>
| <servlet-class>XXXServlet</servlet-class>
| </servlet>
| <servlet-mapping>
| <servlet-name>XXXServlet</servlet-name>
| <url-pattern>/XXXServlet</url-pattern>
| </servlet-mapping>
| <welcome-file-list>
| <welcome-file>principal.jsp</welcome-file>
| </welcome-file-list>
|
| <resource-ref>
| ...
| </resource-ref>
|
| <session-config>
| <session-timeout>30</session-timeout>
| </session-config>
|
| </web-app>
|
And to ensure that the XXXServlet.class is at the correct location, is displayed below of
the output of command:
jar -tf <folder-jboss_deploy>/.war
| ~$ jar -tf <folder-jboss_deploy>/xxx.war
| ...
| META-INF/ejb-jar.xml
| META-INF/jboss.xml
| WEB-INF/classes/XXXServlet.class
| WEB-INF/classes/com/jspsmart/upload/File.class
| WEB-INF/classes/com/jspsmart/upload/File.class.hacked
| WEB-INF/classes/com/jspsmart/upload/File.class.original
| WEB-INF/classes/com/jspsmart/upload/Files.class
| ...

Someone could help me this problem?
Now, thanks!
