Subject Re: [jira] Created: (GERONIMO-645) geronimo/jetty doesn't respect web.xml load-on-startup order
Date Wed, 18 May 2005 02:00:12 GMT
Certainly the simplest solution is to give JettyServletHolder a 
Previous reference so they form a linked list and set this reference in 
the builder so as to be consistent with and enforce the startup order.  
The  JettyFilterMapping uses this idea and I admit I thought I had 
implemented it for servlet holder also :-(

thanks
