JavaServer Faces - Table display in Visual Web JSF (Project woodstock)

[Varnam Aayiram]

Hi...

I am trying to display a table(Quota) from a database in Visual Web JSF(project woodstock) and it works fine, as in I am able to run the project and a browser opens up dislaying the page with the date from the table. However when I try to display another table (Booking) from the same database, I am having problems. The page renders with no content(BLANK) in the browser. I am not sure why this is happening as I am using the same technique used to display content from the Quota table.

This is my jsp code to display the Quota table ( this is the table that loads fine)

Below is the jsp code to view the Booking table ( I am just getting a blank web page when I run the project with this code).

I am really not sure why I can't render the Booking table in the webpage. However in my NetBeans IDE, I am able 'Bind to Data', as in I am able to select the colums from the booking table I want to get displayed. I hope someone can advise. Thanks guys..

I know it's an old post, but I'm having the same problem.

Did you find a solution?

Thanks.
