cvs commit: jakarta-tomcat/src/admin/contextAdmin restart.jsp threadList.jsp

costin      01/04/21 11:28:44

  Added:       src/admin/WEB-INF/classes/tadm ThreadAdmin.java
               src/admin/contextAdmin restart.jsp threadList.jsp
  Log:
  Some more admin pages, showing threads and for "soft" restart ( to test threads
  are cleaned up on shutdown - all modules must be reviewed for resource leaks
  on shutdown ).
  
  Of course, the admin is still looking bad - it's not difficult to add some nice
  html, but the intention is to start a small revolution after 3.3 is done and
  separate the ui from the (trusted ) admin.
