Difference between j2sdkee1.4 and S1SAS

[Sherry Jacob]

Hello Everyone,
I am new to J2EE technology. I was going through Sun's website and found some FAQs on J2EE.

There's some confusion. I already have a j2sdkee1.4 installer, which one of my friends gave me. However I do not know much of it yet as I haven't used it.

While going through the FAQs on Sun's website, I came across Sun One System Application Server. Now, before I download that, I want to clarify a few doubts.

1) Is S1SAS the same as what I already have (j2sdkee1.4) ?
2) If not, what's the difference ?
3) Which one of the two is more widely used considering the industry standards ?
4)Which Java IDE would be best suited for my personal learning and development needs i.e..which IDE is best for development with j2sdkee1.4 and which is the best for S1SAS (if they are different servers) ? My system configuration is PIII 600MHz on Windows2000 OS with 30GB HDD space and 256MB RAM.
5) Time is of the essence...I just have 1 month to pick up everything. Tomcat and JBoss cannot be used.

Thanks alot.

Hi Sherry.

The SDK you downloaded is just the API needed (libraries) etc to run J2EE applications. You also need an application server that implements this J2EE specification. Usually you only need to download the application server itself that comes bundled with the SDK(so you don't need the j2ee1.4sdk download).

It is the same with the tomcat webserver for example:
You can download the j2se JDK and the servlets API etc...(like you probably did sometime in the past), but in order to program and display web pages you need a web server that supports jsp pages etc like tomcat.

Here in the J2EE environment it is the same idea: We need an Application Server to run the EJBs and other stuff we have with the J2EE SDK.

Hope it made it a bit clearer.

As for your choices for application servers:
There are many out there that support J2EE 1.4. Some you need to pay for like Weblogic or Websphere, but others are free.
The most popular one free one is called JBoss.

The one you found is the application server that sun made - version 8.1 i think is their latest.

I recommend either Jboss or the sun application server if you want it to be free.

Hi Mr. Sherry,
u can go through trial versions of weblogic, websphere also which are available in the net for free.... comparitively weblogic is easy to learn, if u have any of friend who knows weblogic its a matter of 30 mins. to understand entire things in weblogic, currently 8.1 version is in the market and about IDE intellej is good to develop your any application and please remember these both are very costly things to use in a company.....
