Yep, you need at least a Servlet container such as Tomcat. Servlets handle
http requests and supply dynamically created html responses.

good luck and

kind regards,

If that's ur urgent requirement then I won't comment anything.
But if you are doing it for learning purpose, then I would rather say, first expertize on web applications. Web services is quite a broad term, and if u are new to java, then u will be lost.

The sequence of learning should be (according to me),
1. Expertize core java field.
2. Expertize Web applications field.
3. Get introduced to (very basic) Web Component development field (EJBs) (optional, but will help in understanding many things.) (I myself am not much introduced to this field).
4. Then come to Web services field.

See wikipedia Link for web services.

Thank you so much jos.
Both these application servers available in my machine.

Sun java system application server 9

I am sorry I didn't mention it in my original post.

I went through this tutorial sample application.
http://qa.netbeans.org/modules/j2ee/.../hello_ws.html
and build the sample application as they have mentioned.

Web service is here.

What is the reason here.

Exactly what the compiler whines about: your class implements the interface
SOAPHandler; that implies that your class is either abstract or not. If your
class is abstract your class doesn't need to implement all methods declared
in that interface. Your class isn't abstract so it should implement all methods
declared in the interface but it doesn't: method getHeaders() is a method from
that interface but your class doesn't implement it.

oops But I failed to solve the problem.

I used the netbeans wizard to create this message handler.

File -> new file -> web services -> message Handler

and add the coding as in the tutorial that i used.

http://qa.netbeans.org/modules/j2ee/...reatingHandler

Did i missed something in my coding.

I'm no web/servlet guru by any means but those exceptions smell like an
installation/configuration error. When the system can't find one of its own
components something is rotten in the state of Denmark.

I apologize for not having a pre-cooked solution for you but if I were you I'd
check the installation of it all. I had to do that once, using Tomcat, and it was
a mess, I can tell you that.

best of luck and

kind regards,

Jos

It's usually advisable to test the installation using one of their test projects that they provide with their programs. Have you been able to deploy the project before?

Thank you guys,

When I build other web Application (Not web services), Netbeans allows me to build, deploy projects successfully.

And i used the tutorial samples under sun/netbeans for Web sevices.

Ok I'll remove the J2SE and J2EE from the system and NB also.
Will be right back after a fresh installation.

Hi,
I reinstalled JDK and netbeans.

Current configurations:

Expand|Select|Wrap|Line Numbers

 
C:\>java -version

java version "1.5.0"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)

Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)

Netbeans 5.5.1 under this location:
http://www.netbeans.info/downloads/start.php
http://us1.mirror.netbeans.org/downl..._1-windows.exe

And I didn't update the IDE for any other add-ons using update manager.

Now the problem is different than previous one.

I tried this sample application.
http://qa.netbeans.org/modules/j2ee/.../hello_ws.html

Again once i come up with deploy it getting this error.
