Error when I try deploy application to tomcat7 server

Question

I am trying deploy a web application to tomcat7 via eclipse luna, but I am getting this error:

Uploading: http://localhost:8080/manager/text/deploy?path=%2Fl         


        

Answer 1

I've had the same issue and in my case the problem was a cunfigured context path not starting with /. Fixing the context path "myapp" to "/myapp" solved the problem.

Answer 2

What's the size of your war? maybe it is because the size too large. By default, tomcat manager only allow less then 50MB size war. also try mvn tomcat7:redeploy instead of deploy.

See here how to increase the war size limit

Answer 3

I dont know if this helps , But in My case . tomcat7 plugin was picking server details from the maven conf settings.xml instead room .m2\settings.xml . Adding server information in that file Resolved my Issue .

Answer 4

By default Tomcat has a max upload size of 50MB. (I.e max size of WAR file)

If you require larger file, try increasing max-file-size and max-request-size within the tomcat web.xml. Note: those values are both stored in bytes.

Edit .../webapps/manager/WEB-INF/web.xml. (Ensure the file sizes are larger than the war file your trying to upload). I.e if you require 80MB WAR,

  <max-file-size>82914560</max-file-size>
  <max-request-size>82914560</max-request-size>

Then restart apache tomcat.

Occasionally problems

If sometimes the redeployment fails, sometimes succeed, a increase of the logging might show a DOS protection.

Edit the /conf/logging.properties and add the line

org.apache.catalina.level = FINEST

At the end of the file. Might show this output:

(in this logging the user who made the attempt to upload has the username admin)

As you see in this output the user admin is locked:

WARNING [http-nio-8080-exec-7] org.apache.catalina.realm.LockOutRealm.filterLockedAccounts 
  An attempt was made to authenticate the locked user [admin]

Look into the documentation and inside the server.xml and you will find a

   <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
           resourceName="UserDatabase"/>

Use unforseeable username

To remove the line is a bad idea, change the username for redeployment to a different, more unforeseeable name like deploy355547511 to not get locked.
