ADF 11g – reducing the price of richness or how to streamline downloading Javascript Resources for ADF 11g Rich Client components

Lucas Jellema 3

  When you run a ADF Faces 11g Rich Client components application, you (or rather your users) are hit with a substantial JavaScript download overhead. It is not surprising, given the richness of the component library. However, especially for internet applications targeted at external users – consumers, customers – it […]

Lucas Jellema 3

  We were faced by an interesting challenge: our JSF application should display boilerplate text – titles, button labels, prompt, error messages, tool tips etc, – in a context sensitive way.

  In a recent article, I discussed how to create a fairly structured hierarchical report – table style – using ADF 10g not-so-rich Faces – see creating-a-read-only-hierarchical-table-report-with-adf-10g.
