Eager Loading

Belongs to following categories: Utility, ULC6.0,

Purpose

This utility class improves ULC's built in lazy loading feature. The main disadvantage of ULC's current lazy loading implementation is the fact that it always requires an extra server round trip to fetch the data. This has the following drawbacks:

• a significant delay over slow networks
• twice as many round trips as necessary
• intial data is blank as it is lazily fetched with an an extra round trip
• updated data first becomes blank as it is lazily fetched with an extra round trip

Resources

• Try out the eager loading sample as JNLP application or Applet application.
• Download the complete source code.
• Download the self-contained war file.

How to use

Register the provided EagerLoadingHandler as round trip listener. That's all!

Compatibility

The described functionality has been developed and tested using JDK 1.4.2_05 and ULC 6.0.2.1
