I am working on a JSP website on JRE1.4. I am trying to find some
good packages to use to speed up development because the project
currently uses no framework whatsoever. Would anyone mind
recommending some good packages? So far Struts looks worthwhile.

JSF will probably look more ASP.NET like to you.

And is much more powerful and flexible.

Since I am from a C# background:

JRE1.4 can't support Nullable<T>, so what is the best practice for
representing null value types?

Arne VajhQj wrote:

Use the wrapper classes Integer, Double etc..

There is no direct Java equivalent to C#'s Nullable<T>.

What are you trying to do with it in Java?

Does JRE1.4 have an alternative to C#'s using statement?

No.

You will need to use try finally.

And should use Java 6, the current version. Java 1.4 is in End-of-Life, it
lacks generics and other useful features, and it is slower than later
versions. Particularly coming from C#, you should find Java 5 or 6 much more
comfortable than the obsolescent version.

P.S., Arne is known to be very knowledgeable about both C# and Java.
