Learning Web Services with J2EE

Hi:
I've been developing in J2EE for 3 years now, using Servlets/JSP/Tag Libraries etc.... I want to find a good source (book) that teaches you web services with J2EE, does anyone recommend any good starters to advance books for Web Services.
Thank you
Goce

Have you looked at the J2EE 1.4 Tutorial?
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
It includes chapters on developing both Web applications and enteprise beans as Web service endpoints.

Preparations to learn Web Services with Java

I have only worked with JSP,JDBC, JavaBeans and Servlets in Tomcat using MVC architecture the past couple years. I have never used Struts framework. I am thinking about taking a Web Services with Java course and was wondering if my background will be enough to keep up with the advance topic of Java web service?

Yes, at first you should have to worry about understanding the basic concepts, WSDL, and a little bit of XML (it does not make very senso to study far too much because sometimes you won't use all the api you may study).
The focus point is understanding that you can build a web service infrastructure passing using many different approaches: starting from wsdl, starting from java, based on WSDL, based on REST and things like that.
JAX-WS is a very powerful toolkit that covers well all the possible approaches you may have.
Anyway starting from scratch is quite frustrating... it is difficult to find around a good guide that covers all the aspects and make you understand the Big Picture. That's really the focus point.
There is a very good book about written by Mark Hansen.
Check out also that there are so many franmeworks around that implements the specification: almost every Corp. implements its own stack.... Sun, Apache, Spring, IBM, JBOSS and so on.
This is quite misleading at first.
Metro is very good and very well implemented with netbeans, and it's easier to start with it. anyway it hides you sometimes what's going on underneath.
I find CXF is a very good framework, and if you love the SPring wayyou should consider give it a chance.
I have no experience of other frameworks.

How to create web services with complex objects as parameters

Hi,
Not sure if this is the right place, but...
I'm using Netbeans 5.5 and trying to learn web services.
Creating a simple web service with simple parameters like strings and integers is nice and easy. I'm now trying to take the next step, and create a web service with a more complex schema as a parameter.
I've tried two approaches, and hit dead ends on both:
(1) Define my complex schema as an xsd file, and then create a WSDL file. Creating the schema and saving it in my EFB project works fine; when I try to create a new WSDL file, the IDE gives me a button to import external schemas - which is where the problem is: the Browse simply won't find my newly created schema file.
(2) Define a Java class (in this case, it's a fairly simple example containing a single ArrayList), and then use the IDE to generate a web service from Java. The IDE does this fine, but I now have no idea how to consume or test the web service - I don't know where to look for the WSDL that has presumably been generated, and I'm also a bit iffy over what answers to give the WSDL creator about port names etc.
Ideally, I'd prefer to get approach 1 to work - can someone point me in the direction of a sensible tutorial for these things?
(Happy to carry on using Netbeans 5.5 or to revert to Sun Studio Enterprise, which I was playing with before.)
All help appreciated, Thanks

- For NetBeans related questions, nbusers mailing list is more suited. It is often visited by NetBeans experts.

The NetBeans users mailing list. General discussion of NetBeans use, this is the place to ask for help and to help others.... (There is a 'Subscribe' button next to the above that you can use to subscribe to the list).
Can you try posting this question on nbusers list?
- SJSE 8.1 is based on an older version of NB (NB5.0).
You should definitely continue with NetBeans, since all development is now being done in NetBeans; all the major JSE modules have been moved to opensource at netbeans.org and are all being developed there. There are as yet no future plans to work on further releases for JSE.

Example website Axis web service?

Hello,
I recently installed Java Axis,tomcat and the file AmazonWebServices.wsdl
And was hoping to write a java program which connects to Amazon's web service.
Does anyone know of a website which demonstrates how to use Axis, and Java code to use the Amazons web services?
Many thanks

The best way to learn web services (like most things) is to get your hands dirty. Play around with some of the sample apps that come with axis. Write your own simple service from the ground up and deploy it. Mess around with the wsdl2java and java2wsdl tools, see what happens with different options. Axis comes with pretty decent documentation, perhaps that would be a good starting point.

Axis web service examples?

J2EE or Web Services tutorial

Is it possible to learn Web Services without knowing J2ee? Which tutorial would be a more worth while tutorial to start with?

Also, you mich look as Axis from sourceforcge. Its a WebServices engine that runs from within Tomcat etc. and is quite straightforward to use.

Utilizing a java stored procedure for web services

Hello,
I am a newbie in web services and I want to learn web services by utilizing a simple procedure and making use as a web service.
I have a java stored procedure deployed in Oracle 8i database, which I am using for sending emails. I am invoking the java stored procedure in my JSP and Java classes by making a database connection and calling the procedure.
I am planning to make this a web service so that I could call this from any of my application.
Could someone give an insight how to make this a web service, albeit the utility is not very complex and my knowledge about web services is limited, I thought I could start by doing a simple program.
Any help is highly appreciated.
Thanks
Ponic

What is a web service address book sample in IBM RAD.

Hi,
I started learning web services by running sample programs provided by RAD. I followed instructions to run the sample to see what the web service will do. But could not. If anyone gone through the example, Can You please take some time to explain.
Thank you.

R u using axis. If you want to stick with axis and don't want to use JBossWS there is nothing else you need to do. Move all the axis to Jboss. If you plan to reimplement all ur services in JBossWS here it is:

Let me know if you need anything else.

If I wanted to learn about Web Services where should I start?

I want to start taking classes, but I'm not sure where to start. I know how to write java programs, but probably more on the level of a school project and simple programs. Is that enough for Web Services or should I take a class before a Web Services class?

Check out JAX-WS at http://jax-ws.dev.java.net. Specifically, check out the Articles under the Documentation section of the page. Bobby has written a very good white paper to get you started.

How to allow access to web service running under ApplicationPoolIdentity

Hi All,
I have a WCF web service hosted in IIS 7 (or maybe 7.5, whichever comes with Windows server 2008 R2) using DefaultAppPool running under ApplicationPoolIdentity per Microsoft's recommendation. The web service needs to call a stored procedure to insert data
to a db. The web server is on a different VM than the database server. The db server is running SQL 2008 R2. Both VMs run Windows server 2008 R2.
When the web service tries to connect to db, it encounters this exception:
Exception in InsertToDb()System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
Here's the connection string in web.config:
Application Name=somewebservice;Server=somewebserver;Integrated Security=SSPI;Database=somedatabase;Connection Timeout=60"
How should I configure SQL security to make this work?
Thanks in advanced.

Thanks for the link Dan. Maybe I'm the one who cause the confusion :)
If I understand you(and Erland) correctly, you suggest using a custom, domain account for application pool identity. However, if we do that, our IT will need to maintain those accounts, and they don't want that. So I'm choosing a built-in account called
ApplicationPoolIdentity as the application pool identity, but it's not working. Network Service, on the other hand, works, but my boss wants us to follow MS's best practice.
What's puzzling is that according to this: http://learn.iis.net/page.aspx/624/application-pool-identities/, both Network Service and ApplicationPoolIdentity uses machine account to access network resource (like db in this case), but in my case, Network Service
works, but not ApplicationPoolIdentity.
Hallo Stephen,
with respect - it seems to me that only idiots are working at your IT ;)... It is absolutely useful to work with "service accounts" created within the domain. That's the only way to manage and control accounts!
If you want to "pass through" the identity of the web user (SSO) you have to check whether the app pool is set to "allow impersonate". As far as I understand the ApplicationPoolIdentity-function the app pool will create a unique user named as the service.
I assume that will not work with the connection to the sql server because this user is unknown.
Local Service will not work because it's restriction is located to the local machine.
Network Service will work because access to network resources will be available.
So my recommendation is to use a dedicated service account or impersonation:

Return multiple values from a Web Service

Hi,
I'm learning JAX-WS web services and I'm wondering, how do I return multiple data like, say multiple rows from a table through a web service? I understand that I can use Holders, but those are for JAX-RPC if I'm not mistaken, and I'd like to know the alternative for JAX-WS(if there is any).
Any help would be much appreciated.

A greeting service where the client types a string(preferably a name), and the service returns "Hello, " followed by that name. I faced the error with returning objects when I tried to return the results of a query with a set of serialized JavaBeans passed into an arraylist. I don't have the complete error log with me now, but the error was generated when deploying with JDeveloper 11g, and it was something about JAXB content model error. Also, There was an error regarding javax.naming.Name saying that JAXB couldn't handle interfaces.yes, you can't return any interfaces. so, instead of returning a List, you have to return an ArrayList. if you use xjc to generate types from a schema, then it will normally generate a "wrapper" class around any collections (which will in turn hold a List).
