j2ee postings on server side

Whenever I have a minute I try to share some of my j2ee experience on the server side forums. Here are a links to a few threads of general interest I have participated in:

• Http Referer - how to only accept visitors comming from a precise URL
  
• ejb and servlet container class loader configurations
  
• websphere startup class resources
  
• about statefull session beans
  
• generic algorithms - a more flexible alternative to big switch / case statements
  
• the eternal question: when to use j2ee?
  
• someone was wondering if they sould use the file system or a database blob to store xml files
  
• someone else was wondering how to use j2ee transactions with ejb / servlets configuration
  
• another person was wondering about the utility of using a data access objects layer in conjunction with a ORM framework in distributed applications.
  

Enjoy.
