migrate JSP website

First of all, im not a beginner in JSP, in fact, i dont know anything. i learnt java before but i dont know JSP.... My expertise is in PHP

My question is, one of my client want me to help moving his website from 1 hosting service to another. Of course, the website is created using JSP. It include backend database, shopping carts, ecommerce...

I've experiences in migrating websites from 1 hosting to another. But all are written in PHP or Pearl...

So my question before i take the job is does migrating JSP website different with other website? Any thing i need to keep in mind? Any code i have to change? (of course, after this i would be googling what about JSP to know how to do it... Just a few basic head up for beginner is very much appreciated)

For those who dont know about migrating other website than JSP this is pretty much all coding requirment you need to do: change the database connection information (database name, host name, username, password), backup database and create another database on the new host, just copy and paste sql code retrieved to the phpmyadmin.

Oh by the way, i only know mysql. What database do JSP use? differences? connection script sample?

thank you so much for helping me

Hi
There may be change in Code if variation on Java Version in any of servers(old and new). For eg, Application A hosted on old Server with version 1.1, now new server you have to have the same version. If you are looking for going to higher version, you need to change the code.

Jsp support all databases. you need to install corresponding drivers in your class path. It provides standard way of accessing all databases.

Thanks & Regard,

Do i have to recomplie all of the files again....
And do i have to have the same java version?
