java - Publishing failed in tomcat after package change -

i have simple web application working fine when had default package. when added package & moved classes them, deployment fails error :

the servlets named [fileuploaddbservlet] , [com.db.fileuploaddbservlet] both mapped url-pattern [/fileuploaddbservlet] not permitted 

i tried deleting old project & creating new one. somehow old reference still exists. how can remove old references.

i using java 7, tomcat 8 & eclipse

thank help.

i identified solution problem.

in web.xml, both servlet-class , servlet-name should qualified :

  <servlet> <servlet-name>fileuploaddbservlet</servlet-name> **<servlet-class>com.db.fileuploaddbservlet</servlet-class>**  </servlet> <servlet-mapping> **<servlet-name>com.db.fileuploaddbservlet</servlet-name>** <url-pattern>/fileuploaddbservlet</url-pattern>
