Migrating from Tomcat to Sun Application Server

Hello Friends

I am currently working on the projects dealing perticularly to jsp , servlets , javabeans and deploying them on the Tomcat Server.

I am moving to EJB now
so can any one suggest me which Apllication Server wiould best fit for this purpose.

I have downloaded the J2EE SDK 1.4 with Sun System Application Server 8.0
and Bea WebLogic Server 8.1

I started with Bea WLserver but it seems to be some what difficult for me and since I am new to EJB environment I am feeling thet I should go step by step so I started with Sun SA Server.

I have deployed my first sample ejb application on it.

can I use Sun System Application Server for commercial use ?
ie for installing it at WebServer.

any suggestion for learning EJBs are welcome.

Hi
Choosing an Apps is higly depend on what you need ,
BEA weblogic is a full blown application server and its commerical with many features.you can not use if for deploying you application for commercial use.

Sun Apps 8.1 is free for use for commercial .
Best way for you , IMHO is to get netbeans 4.1 which is boundled with Sun APPs 8.1 and use it to convert your application because it suports both Sun apps and tomcat + very good JSP and EJB development.

----
there are some other certified APPS like :geronimo from apache , JonAs , Jboss and other but i Suggest Sun APPS if you want a free.
----
for resource :
if you do not know EJB then take a look at SUN j2ee 1.4 tutorial available in sun j2ee site.

for using NetBeans for j2ee developing ,there is a very nice and handy book from netbeans.org which you can get freely.

hope it helps

Thanx for ur help

I have tried NetBeans too
but it gives some xmlns parse error when i try to create a new project.

and it works fine on another machine.

I had tried reinstalling it but the problem was not solved.
how could i solve this error???

also my collegue had a problem of the database recordset with it.

how could i solve this error???

If you want help from someone here, you need to post the error (otherwise all anyone can do is make wild guesses). And if it is an error with NetBeans, you will get a better response if you post you problem in the IDE's forum.

I get following error when i try to create new project in netbeans

-------------------------------------

org.xml.sax.SAXParseException: duplicate attribute (found "xmlns")

Please help.
