Do I still need jsdk*.jar? ... and where can I it?

Folks please,

What is jsdk.jar (or jsdk*.jar) ??? Do I still need it to write/run servlets? ... and if so, where can I download it from? ... and does anyone know the correct version for my existing setup?

I'm doing Chapter 1 of the Hibernate tutorial at: http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html
which states

Quote:

Before you compile and deploy the web application, note that an additional library is required: jsdk.jar. This is the Java servlet development kit, if you don't have this library already, get it from the Sun website and copy it to your library directory. However, it will be only used for compliation and excluded from the WAR package.

and yep, when I build I get "ant war" output:

Code:

Buildfile: build.xml

clean:
   [delete] Deleting directory C:\Java\src\Tutorials\Hibernate\bin
   [mkdir] Created dir: C:\Java\src\Tutorials\Hibernate\bin

copy-resources:
     [copy] Copying 4 files to C:\Java\src\Tutorials\Hibernate\bin
     [copy] Copied 2 empty directories to 1 empty directory under C:\Java\src\Tutorials\Hibernate\bin

compile:
    [javac] Compiling 5 source files to C:\Java\src\Tutorials\Hibernate\bin
    [javac] C:\Java\src\Tutorials\Hibernate\src\events\EventManagerServlet.java:4: [b]package javax.servlet.http does not exist[/b]
    [javac] import javax.servlet.http.HttpServlet;
    [javac]                           ^
    .... lots more javax.* not found, and a few typos .... 

I'm using Hibernate 3.1.3 (March 20, 2006), on HSQL-DB (which I presume is packaged with hibernate) and Apache Tomcat 5.5.17 (circa August 12, 2006)

I just down loaded Enterprise Edition 5 SDK Update 2 (Sun Java System Application Server Platform Edition 9):, which I thought would include jsdk.jar ... but I've search My Computer and still can't find any "jsdk*.jar"

... so I had a bit of a dig around Suns website and came up with http://java.sun.com/products/servlet/download.html which says

Quote:

J2EE 1.4 SDK contains an implementation of the Java Servlet 2.4 specification.

, and if you follow the tomcat link on that page to http://java.sun.com/products/jsp/tomcat/ it says

Quote:

Tomcat 5 supports the Servlet 2.4 and JSP 2.0 specifications.

So I reckon I've got everything I need, and now I suspect that jsdk.jar is defunct ... so what's it's replacement? so I searched my computer (note to self: must get smaller harddisks next time) for "*.jar" containing text "javax.servlet" and came up with another blank.

... and I'm so confused ! ...

Please can anyone shed any light?

Thanx. Keith.

Google to the rescue again...

I just went simple and googled "jsdk.jar" ... near top is:
http://www.arcknowledge.com/gmane.comp.cms.open-xchange.user/2005-06/msg00066.html
which says

On my Tomcat 5 installation it's actually called servlet-api.jar. Try looking for that.

yep, I found servlet-api.jar in C:\Program Files\Apache\Tomcat5.5\common\lib and yep, it contains javax.servlet.*

So ... dear Hibernate Team, Please could you update (or make a note in) The Hibernate Tutorial, to save lots of newbies a couple of hours (each) ... and if you need a volunteer then I'm volunteering.

Cheers all. Keith.

If I type "jsdk.jar" into Google, the first hit is this: http://www.devdaily.com/java/edu/jb/jb0 ... ndex.shtml

And why do you expect the Hibernate documentation to also include a Servlet tutorial? Most readers would say "Gee, I don't know what this Servlet stuff is about, maybe I should skip this section!".

Seriously, I think it's important that information presented to "first time users" be impecable... troubles in the early stages can have a disproportionate negative impact on a "first time users" perception of product quality... doco & tuts included.

How long does "the average user" persist with a buggy instal?

I was serious with my offer to update the Hibernate Tutorials to note the change between Tomcat 4 (jsdk.jar) & 5 (servlet-api.jar).

So I'm not most people. Shoot me.

Kindest regards. Keith.

I was going to post something extemely narky in response to this, like "Yep, and what's that got to do with anything?" but I have decided to refrain in favour of a dignified silence.

Odd reaction - my thought was that Christan was more helpful as he showed you not only the answer but a method to get it faster than a forum. I think that is very helpful and educational.

I just wanted to say that I agree with "wookie2u". The reference to jsdk.jar is very confusing and the link given in the response was a very bad example.
No, the tutorial was not about servlets but about hibernate, but it is not good if we newbies get stuck with servlet problems trying to get hibernate working.
Thank you "wookie2u" for giving me/us the details about servlet-api.jar

Thanks for a good forum!
