Re: New and confuse - WebSphere Express 6.1 and JVM on V5R4

I'll start by saying WebSphere is usually behind the times as far as app
servers go.

1) Is Websphere Express 6.1 the latest available version for V5R4?
No, I think you can install WebSphere 7.0, but I have no personal experience
with it. It does run Java 5 EE though.

2) Is WebSphere Express written in java? If so, how can I figure out
what version of JVM it is using?
Don't know what it's written in, but I would assume Java. It runs on Java 5
(1.5). You can have it run under the classic 64-bit or new 32-bit Java 5 (if
it's installed).

3) Can our application that will be running in the Websphere Express run
in any version of supported JVM on V5R4? (Independent of what WebSphere
Express is using (Assuming that Express is written in java)?
Can't tell you for sure not knowing anything about your app, but most likely
it should. You would need to make sure you get all the libraries need, if
custom, installed.

4) What is the different between the Classic JVM and IBM(r) Technology
for Java(tm) JVM?
I'm not sure what the differences are. I actually was looking for this
yesterday, but could not find it. The new 32-bit JVM is supposed to be
faster. This link might give you some information though.

I'm a Project Management that has primary been working on the RPG side

helping them move the current application server from jBOSS to websphere
Express. The primary reason for this move is because we are currently
using a very old version of jBOSS which is currently running our web
team's applications using classic JVM 1.4. The ultimate goal is to move
it to the newest support version of Websphere Express and JVM on V5R4.
Below are some questions that I seems to not able to Google out:

1) Is Websphere Express 6.1 the latest available version for V5R4?
2) Is WebSphere Express written in java? If so, how can I figure out
what version of JVM it is using?
3) Can our application that will be running in the Websphere Express run
