hi
i'm totaly new on ejb topic and i have one question regarding the " what u need for this book" page.

i used j2se1.4 and tomcat5 by now to develop servlets and jsp.

The first thing they say : download j2ee 1.3.x -it includes the jarfile with the entire j2ee api...

then next sentence says: The j2ee sdk does not include the api documentation...

???
question 1.
is there any difference between "j2ee" and "j2ee sdk"?
question 2.
what is actually j2ee?
is that a underlaying class-libaris like in j2se?
or is it an ejb container?
or is it an ejb container and web container?
or is it an ejb container and web container and underlaying class-libaris?
and
can i still run my "j2se1.4 and tomcat5" system and paralel instal
j2se1.3.x and j2ee1.3?
tia

The Java 2 Platform Enterprise Edition (J2EE) is an (inter/intra-net) distributed component architecture which includes the Java 2 Platform Standard Edition. An J2EE application server must include a Web Container (Servlets,JSP), an EJB container and must also support some other technologies as specified by the J2EE Specification.

The J2EE 1.3 RI is a reference implementation for an J2EE 1.3 application server by Sun Microsystems - it is not intended for production use.

SDK - Software Development Kit: this usually indicates that distributable includes additional tools for software development - in addition to the bare runtime executables and libraries. The J2EE 1.3 RI for instance includes the deploytool.

The download link for the J2EE 1.3 RI can be found on this page
Java 2 Platform, Enterprise Edition (J2EE) - Version 1.3.1 Release
Look for the Download icon under Download the Software for the Java 2 SDK, Enterprise Edition 1.3.1.

Don't forget to grab the EJB 2.0 Spec.

JavaTM 2 SDK, Enterprise Edition 1.3.1 Documentation

You don't have to install J2SE 1.3. The server works fine with J2SE 1.4.2. It will not work with JSE 1.5!

You can keep Tomcat - just don't run the RI and Tomcat at the same time in case they want to use the same resources (ports etc.).

hi Peer,

i have J2SE Development Kit 5.0 update 4 , and Tomcat_5.5.x

i have to uninstall 5.0 and tomcat_5.5.x(since tomcat_5.5.x required 5.0), and download the rest that you were mentioned above right???

no other choice?

The RI will not work with JSE 1.5. Maybe if you go back and also install J2SE 1.3 and manipulate the environment variables before you switch back and forth you might be able to keep your previous installation.

In my case I had both the latest version of 1.4 and 1.5. However the Win32 versions of the JRE/JDKs seem to use the Windows registry to setup the environment (bypassing the environment variables on the location of the JRE; indicating the endorsed library locations, etc.) - fiddling with the environment variables (PATH, CLASSPATH, JAVA_HOME, J2EE_HOME, etc.) isn't enough. I finally lost patience, and uninstalled JSE 1.5, as I had no compelling reason for keeping it.

If you manage to get it going, post the results - I sure that some people would be interested in it.

This may give you a start how to switch JDK version on Windows.

I also left some tips on how to manipulate the registry in Working with the Registry.
