j2ee1.3 vs. j2ee4 and HF-book ejb2.0 exampels

[Ner min]

i just realised that running j2sdkee-1_3_1-win.exe with jdk5 wonnt work.
so i asked my self is it really nesecery to go with the jdk1.3 and this j2sdkee-1_3_1-win.exe in order to compleate the HF-book?

ok i will try other way - is ejb2.1 backwarts compatible with 2.0?
if so, couldunt i use some of this sun app-servers 8.x or so, couse they are j2ee1.4 compatible and j2ee runs ejb 2.1? so i dont have to uninstall jdk5?

is anybody tryed this HF-book ejb2.0 examples on any j2ee1.4 app-server and if do they work?

Hi,
there is no need to uninstall.simply point to the jsdk that you want to use 1.3 or 1.4 or 1.5.You can install multiple jdk.

thanks Rajan,

but do you know are this j2ee1.4 compilant servers(or ejb2.1) backwarts compatible with the ejb2.0?

Normally it should be with all the servers otherwise an application which was developed spending lots of resources(money,time,manpower etc) just ends up being tied up with one server/vendor.What good is that? at the end spec is to make the application vendor independent.So,it will be possible may be with little tweaking with some code and/or the depl descriptor.May be others may be able to tell specific restrictions and requirements if any.
