Java EE 5 vs. J2EE 1.4

[skaterdav85]

I'm setting up a jsp application in NetBeans, and I have the option of choosing Java EE 5 and J2EE 1.4 for my Java EE version. Does anyone know what the difference is?

Lots of differences.

J2SE(TM) 5.0 New Features

Compare this with the 1.4 feature list.

I set it up trying both versions and my jsp application won't run using j2ee 1.4. Is this due to my Tomcat container requiring more API's, thus the need for Java EE 5?

What you mean by application wont run? Did you end up with an error.

By the way how did you configure the web server to use both versions.

ya i did get an error. However, I am trying it again and it works...not really sure why. Regarding the web server, I didn't do any configurations. I just downloaded NetBeans and installed everything and it let me choose between those two versions.

Do you remember the error message you comes with initially? If so can you send it here. Just compiling the errors cannot vanish, unless something wrong with linkers.
