I followed the instruction in the following link, it works for me. http://www.coderanch.com/t/487178/Tomcat/war-file-show-load

Stop Tomcat

Delete all the logs in tomcat/logs and all files in tomcat/conf/Catalina/localhost

Remove the war file and the directory it created (if it did) from tomact/webapps

Start Tomcat

While watching the logs, copy the war file to the webapps directory again

After this, keep an eye on the catalina.xxxx-xx-xx.log to find out the issue.

You can access your application from  http   localhost 8080 sample  Deploying or redeploying of war files is automatic by default - after copying overwriting the file sample war  check your webapps folder for an extracted folder sample   If it doesn t open properly  check the log files  e g  tomcat logs catalina out  for problems with deployment

If you installed tomcat7 using apt-get in linux then  deploy your app to  var lib tomcat7 webapps   eg   sudo service tomcat7 stop  mvn clean package sudo cp target DestroyTheWorldWithPeace war  var lib tomcat7 webapps   you might also want to make sure war file has permission   777  not just   x   sudo service tomcat7 start   Also  keep tailing the tomcat log so that you can verify that your app is actually making peace with tomcat   tail -f  var lib tomcat7 logs catalina out   The deployed application should appear in http   172 16 35 155 8080 manager html

This has been working for me    Create your war file  mysite war  locally  Rename it locally to something besides  war  like mysite www With tomcat still running  upload mysite www to webapps directory  After it finishes uploading  delete the previous version mysite war List the directory  watching for the directory  mysite to disappear  Rename mysite www to be mysite war List the directory  watching for the new  mysite to be created    If you try uploading the new file as a war file  with tomcat still running  it will attempt to expand it before it is all there   It will fail   Having failed  it will not try again   Thus  uploading a www file  then renaming it  allows the whole war file to be present before tomcat notices it   Hint  don t forget to check that the war file s owner is tomcat  Use chown

There are two ways    Either you can do hot deployment  Hot deployment means deploying when server is running up   Or you can do cold deployment  Cold deployment means deploying when server is stopped     Just use tomcat manager console for console deployment or simply copy and paste your application in webapp folder of your server s tomcat home directory   Note  Make sure if your war file size is more than 52 MB  the default configuration value   you need to make two little changes in web xml file of Manager application of your webapp folder Manager application is provided by Apache tomcat by default upon installing the server     Go to the web xml of the manager application  for instance it could     be under  tomcat7 webapps manager WEB-INF web xml  Increase the max-file-size and max-request-size values in web xml file    lt multipart-config gt        lt      50MB max     gt        lt max-file-size gt 52428800 lt  max-file-size gt        lt max-request-size gt 52428800 lt  max-request-size gt        lt file-size-threshold gt 0 lt  file-size-threshold gt     lt  multipart-config gt    Increase the size by putting the values for  lt max-file-size gt  and  lt max-request-size gt  according to your requirement

In addition to the ways already mentioned  dropping the war-file directly into the webapps-directory   if you have the Tomcat Manager -application installed  you can deploy war-files via browser too  To get to the manager  browse to the root of the server  in your case  localhost 8080   select  Tomcat Manager   at this point  you need to know username and password for a Tomcat-user with  manager -role  the users are defined in tomcat-users xml in the conf-directory of the tomcat-installation   From the opening page  scroll downwards until you see the  Deploy -part of the page  where you can click  browse  to select a WAR file to deploy from your local machine  After you ve selected the file  click deploy  After a while the manager should inform you that the application has been deployed  and if everything went well  started    Here s a longer how-to and other instructions from the Tomcat 7 documentation pages
