[Former Member]

Hi all

I am just new to both the areas !

Just want to know what are the difference exists between J2SE SDK 1.4.2_XX and Java EE 5.

Please put some lights on the differences !

Can I use <b>SAP NetWeaver Composition Environment 7.1 Trial Version SP1 Preview - Java EE only</b> for any Java/J2EE development ?

If I can, then which Java/J2EE Standard does my program will belongs to ?

Thanks

JDK1.4 and JavaEE5 are not the same things.

JavaEE5 should run on JDK5 or later.

JAP and JAXWS of JavaEE5 make programming more simple.

of course you can develop applications of JavaEE5, and eraly version, J2EE1.4/1.3

Thanks Shen !

During the Installation of the S/w, Do I get any Opportunity to select between JavaEE5 and J2EE1.4 etc ?

HI Kamesh,

There is no need of such selection. The server is fully compatible with both Java EE 5 and J2EE 1.4 and can run both type of applications.

However there are some key features in Java EE 5 (especially in the EJB area) that make it much more easy to develop new applications. So if you are starting now, it makes sense to start with Java EE 5.
