I need very good java servlets coder who also know everything about Apache/tomcat server running.

I have java servlet what open web pages adapted for viewing on mobile phone ( similar as www.google.com doing when you type any URL in MOBILE PHONE browser )

BUT I have problems with servlet working. Servlet problem begin when visitor on web page click on link to load pdf/doc file and servlet try to load doc/pdf, servlet enters into an infinite loop, consuming all server memory resources, up to 500 MB ( I have VPS server with 512 MB memory ) and than I need to restart server. I need coder to correct this mistake. Also there are some mistakes in servlet code and I need some improvement in servlet. Worker basic task is:

1. limit load web pages only to html ( not load pdf / doc etc...files and go to infinite loop )

2. rewright servlet code to be 100% correct ( test servlet and fix bugs )

3. do not show or prevent from editing EX. ..www.xyxy.com in browser when servlet load webpage ( I will explain in details this problem to serious bidders/worker )

4. Make servlet ( war ) possible for editing default websites what servlet will load ( I will explain in details this problem to serious bidders/worker )

5. limit nubers of external webpages what visitor can load ( I will explain in details this problem to serious bidders/worker )

6. Installing servelet on server and give me instructions how to manage/edit servlet if I will need it in future
