The tomcat manual says      Copy the web application archive file into directory  CATALINA HOME webapps   When Tomcat is started  it will automatically expand the web application archive file into its unpacked form  and execute the application that way

copy the  war file in the webapps folder upload the file using the manager application - http   host port manager  You will have to setup some users beforehand   not recommended  but working  - manually extract the  war file as a  zip archive and place the extracted files in webapps webappname   Sometimes administrators configure tomcat so that war files are deployed outside the tomcat folder  Even in that case   After you have it deployed  check the  logs dir for any problems   it should be accessible via  http   host port yourwebappname   So in your case  one of those   http   bilgin ath cx TestWebApp  http   bilgin ath cx 8080 TestWebApp    If you don t manage by doing the above and googling - turn to your support  There might be an alternative port  or there might be something wrong with the application  and therefore in the logs

As others pointed out  the most straightforward way to deploy a WAR is to copy it to the webapps of the Tomcat install  Another option would be to use the manager application if it is installed  this is not always the case   if it s properly configured  i e  if you have the credentials of a user assigned to the appropriate group  and if it you can access it over an insecure network like Internet  but this is very unlikely and you didn t mention any VPN access   So this leaves you with the webappdirectory   Now  if Tomcat is installed and running on bilgin ath cx  as this is the machine where you uploaded the files   I noticed that Apache is listening to port 80 on that machien so I would bet that Tomcat is not directly exposed and that requests have to go through Apache  In that case  I think that deploying a new webapp and making it visible to the Internet will involve the edit of Apache configuration files  mod jk   mod proxy    You should either give us more details or discuss this with your hosting provider   Update  As expected  the bilgin ath cx is using Apache Tomcat   Apache HTTPD   mod jk  The configuration usually involves two files  the worker properties file to configure the workers and the httpd conf for Apache  Now  without seeing the current configuration  it s not easy to give a definitive answer but  basically  you may have to add a JkMount directive in Apache httpd conf for your new webapp1  Refer to the mod jk documentation  it has a simple configuration example  Note that modifying httpd conf will require access to  obviously  and proper rights and that you ll have to restart Apache after the modifications   1 I don t think you ll need to define a new worker if you are deploying to an already used Tomcat instance  especially if this sounds like Chinese for you

Note that you can deploy remotely using HTTP        http   localhost 8080 manager deploy            Upload the web application archive    WAR  file that is specified as the   request data in this HTTP PUT request    install it into the appBase directory   of our corresponding virtual host  and   start it using the war file name   without the  war extension as the   path  The application can later be   undeployed  and the corresponding   application directory removed  by use   of the  undeploy  To deploy the ROOT   web application  the application with   a context path of       name the war   ROOT war    and if you re using Ant you can do this using Tomcat Ant tasks  perhaps following a successful build    To determine which path you then hit on your browser  you need to know the port Tomcat is running on  the context and your servlet path  See here for more details
