tomcat7 - I have to add custom realm jar file to tomcat 7's lib folder. How will i do this on a shared hosting server -

i have created custom realm jar file , have add tomcat server's lib folder custom realm work. works fine when deploy application on local tomcat server. question how add jar server's lib folder on shared hosting server, if buy shared jsp hosting account. there provision doing so, , if not, alternate this.

i don't expect shared hosting provider allow add arbitrary jar file shared lib folder. may need contact hosting provider , ask/plead/beg them so, , in case may want (i should hope do!) @ source make sure aren't doing unsound/unsafe/evil.
