Which is the BEST Java Web Service Framework to use?

Hi all,
I'm a beginner to Web Services.
I am planning to implement java web services to make the communication between java(Tomcat Server) and C# client.
I found list of web service frameworks like,
1. Apache Axis,(POJO,Axiom)
2. JSON-RPC,
3. Java Web Services Development Pack ,
4. Web Services Invocation Framework,
5. Xfire,
6. XML Interface for Network Services. ...
Please do reply me that which web service framework will be efficient to use.

But, I want to know which Framework will provide
better performance?
better than what?
Also I want to develope the web service as a standard
one andeach has it's own quircks and implementation details. Each should be able to generate and accept the same SOAP messages though if you implement them properly.
It should be able to provide bulk data exchange.
That will depend in large part on your hardware.
Please suggest a web service framework
(Java-based) which will give better performance.again, better than what?
Better than messenger pidgeons?
Better than swallows (European or African)?
And if so, how heavy would the message capsule be? 2 swallows may be able to carry a coconut together, holding it on a piece of string.

The Best Java Web Services Technology for Developing Web Services

Hi,
I am new to Web services world.
I read the java web services page . there are more than 6 technologies.
JAX-WS,
JAX-RPC,
JAXB,
SAAJ,
JAXP,
WSIT,
XWS-Security
I went through several documents on web services.
I could not get a clear idea of which technolgy to use.
Which Java web service technology will be the best to develop web services independant of language, platform.
or is there any 3rd party implemetations available ? for rapid development of web services.
Could anyone help me !.
Thanks in advance.

Which Java web service technology will be the best
to develop web services independant of language,
platform.
Java by nature is a cross-platform language, so if your focus is on the need for portability, the choisce of WS should not be a problem. However, each WS is best suited for paricular uses.
SAAJ, a low-level level API, offers much simplicity, but is not the first choice for programmers, as SOAP (Simple Object Access Protocol)messages need to be constructed piece by piece, making it a quite arduous code to program.
If you are not familiar with XML, your best bet would be to use JAX-RPC (Java API for XML-Remote Procedure Calls), as it hides the underlying detail from the programmer, in terms of SOAP and XML. The shortcoming with RPC-based WS is that it is "restricted to the local programming experience". Another failing is that assumes there is a network path- a reliability concern.
If your program will be contacting other services during downtimes, unlike JAX-RPC, JAXM is quite useful. However, your listing did not mention it, so I wont cover it.
JAXR is a client-side only API that acts as an interface between registries (not referring to JAXP)
I am not famiiar with JAXB, JAXP, WSIT or XWS-Security..
or is there any 3rd party implemetations available ?It depends on what platform you are used to. Assuming you are familiarized with the J2EE platform (now changed to Java EE SDK), the NetBeans IDE (either 5.5, 5.5.1 or the latest editiion) is quite useful. I am using 5.5.1, but have found that it is quite buggy, especially when adding WS operations, a core requirement of a WS. if you will be using to devlop a service for an immediate need, you may find the learning curve to be a bit high, in terms of getting to grips with how to use it. (Download link:
http://www.netbeans.info/downloads/index.php)
The IBM Autonomic IDE (or AIDE), based on the WSDM standard, includes 3 sub-tools, icluding the IBM Manageability Endpoint Builder which, according to their website, allows individuals to build endpoints to allow manageability interface exposure; Manageable Resource Browser and the IBM Manageability Endpoint Simulator. However, I'm not familiar with this IDE. (Download link: http://www.alphaworks.ibm.com/tech/aide/download)
The .NET Framework uses the Visual Studio IDE. For an unbiased comparison of J2EE and the .NET Framework in terms of WS, see http://www.webservicesarchitect.com/content/articles/hanson01.asp.
Apache Axis2, Geronimo and JiBX allows fast development of WS, or so the creators profess.
The PHP environment- you could try NuSPHERE PHPed. According to one website, with it you can develop a web service in under an hour.
I hope this was useful to you.

Receiving the internal 500 error while testing java web service in integrated weblogic server.
my scenario is like,
retrieve the Payload from Dehydration tables.
We are connected to SOA_INFRA schema and we are retrieving the payload from the dehyadration tables based on InstanceId and ECID using Java Classes.After that i make it as a web service and i deployed in to intergrated weblogic Server.It is generating the Target End Point URI.When am i hitting this it is showing structure of the service.I am testing this service from soapUi it is returning the Server internal error with 500.Here i am passing inputs as InstanceId and ECID.

"The Java Web Services" - ant install

Hi, I recently downloaded "The Java Web Services" and "The Java Web Services Tutorial".
And I've reached the Creating the Build Properties File portion of the tutorial:
http://java.sun.com/webservices/docs/1.0/tutorial/doc/GettingStarted2.html#73059
I'm using Windows ME and I have no idea where to put the build.properties file.
Can anyone give me any suggestions? I am successfully able to
ant compile
but I can't get
ant install
to work once I have done the ant compile and I suspect this is because of me not having the build.properties file set... although it could be unrelated to that.
when I try to use:
ant install
I get the following error at the command prompt:
C:\tim\programs\jwsdp-1_0\docs\tutorial\examples\gs\build.xml:46: java.io.IOExce
ption: Server returned HTTP response code: 401 for URL: http://localhost:8080/ma
nager/install?path=%2Fgs&war=file%3AC%3A%5Ctim%5Cprograms%5Cjwsdp-1_0%2Fdocs%2Ft
utorial%2Fexamples%2Fgs%2Fbuild
Now tomcat is running on the correct port (8080) and the directory being referenced in the above URL exists. Am I supposed to map tomcat to a particular file system or something?
Thanks,
Tim
PS I have another post in this forum (it contains only my first question concerning the build.properties file), so if you would like the Duke dollars for both posts, feel free to post in both threads and if your answer helps me out, I'll give you the Dollars from both threads.

Hi Tim
I have the same problem with the build.properties file. i am not able to solve the problem. did u find any solution for that problem u had. so plz let me knpow about that. i would appreciate if u could mail mne at [email protected]
thanks in ADV.

Could not run the bookstore1 example from the Java Web Services Tutorial

The bookstore1 servlets example from the Java Web Services Tutorial (issue Aug 1, 2002) was built and deployed successfully by using the deploytool (following the steps described on pages 498ff of the tutorial).
After deploying the application the Tomcat Web Application Manager shows the entry:
/bookstore1:stopped:0:D:\Programme\Java\tomcat\jakarta-tomcat-4.1.8\work\Standalone\localhost\manager\bookstore1.war
when entering the command: http://localhost:8080/manager/list.
After entering the command: http://localhost:8080/manager/start?path=/bookstore1, the (uncomplete) message appears:
FAIL - Application at context path /bookstore1 could not
It should be noted that I was able to build and deploy the application GSApp (chapter 3 of the tutorial) successfully.

Did you set up the database as described in
http://java.sun.com/webservices/docs/1.0/tutorial/doc/WebApp13.html#69868

Is there a new version of the book "Beginning Java Web Services"?

I am new to programming web services with Java. Is Beginning Java Web Services a recommended book for a beginner? Does it have a newer version as the one available was written in 2002. Can anyone suggest a latest beginners guide book?

The MD387LL/A, MD388LL/A, and MD389LL/A are the latest models in the USA and Canada. It's the same in other countries, except for the LL.

Cannot complie the example at Java Web Services Tutorial 1.3,Ch3

Hi all,
At the Java Web Services Tutorial 1.3 Chapter 3, there has an example but I cannot compile!
The is the output of ant:
C:\jwsdp-1.3\jwstutorial13\examples\gs>ant build
Buildfile: build.xml

Would you please give me an idea to solve this problem?
Thanks
Chris

Ok...this is driving me nuts!!!
I am getting the same error (blah blah blah...ListTask cannot be found) and I have looked over the forum and copied over the catalina-ant.jar file into the apache-ant/lib dir. I have also included every path I can think of in the PATH env var and CLASSPATH env var...
PATH = C:\jwsdp-1.3\jwsdp-shared\bin;D:\pipeline\products\cygwin\bin;D:\Ant\apache-ant-1.5.4\bin;C:\jwsdp-1.3\apache-ant\bin;D:/pipeline/products/jdk;D:/lcms/products/jdk
pipeline is where my jdk (I have two different versions because two different apps) is and the ref to D:\Ant...is for another app.
CLASSPATH = C:\Program Files\Altova\xmlspy\XMLSpyInterface.jar;C:\jwsdp-1.3\server\lib\catalina-ant.jar;C:\jwsdp-1.3\common\lib
ignore the XMLSpy stuff
please help...thanks ahead of time.

Java web service -- how to re-generate Java sources when WSDL changes?

I created a new web service using the "Java Web Service from WSDL" wizard.
Some time later I changed the WSDL and now I need to rebuild the Java sources. What is the best way to do this? I can't re-run the wizard, it returns an error: "The name of this web service is already used by another web service in this project."
Using Jdeveloper 11.1.1.3.0 on Linux.

Error when calling Java Web Services from ABAP.

Hello experts:
    In my project, I will call Java Web Services with ABAP coding. With WSDL, I generated a proxy class and created a HTTP connection (t-code: SM59) and a logical port (t-code:lpconfig) for this proxy class. But when running, I would receive the folllowing errors:
   SOAP:1.023 SRT: Processing error in Internet Communication Framework: ("ICF Error when receiving the response: HTTP COMMUNICATION FAILURE")
   If I used HTTPS, there is no problem.
Regards
Bob

Hi Bob,
It might be the possibility that your java web server is configured to listen only on HTTPS.
If your HTTPS is working fine, then first check with your JAVA server for HTTP connectivity, then try it calling through ABAP.

Piyush

Newbie question to java web services....

hi,
I used to be a .net programmer for a few years, and am have done web services in .net.... (using IIS, of course)
And i moved onto Java side recently - and am pretty new to tomcat / axis..etc..
I looked at the netbeans ide tutorial, and it covered on how to create a web services and a client using the IDE - with that is with the sun app server. Since I want to stick with Tomcat (which is a servlet container, i believe), the compilation complained that the HelloWSImpl.java is not a servlet, and will not let me run the web app. I have tried the WSDP 2.0 tutorial as well, but I first got the FastSetsource.jar not found? Then I got some other classes not found..etc... so, until now - i still am not able to create a web service, and a cliet to talk back and forth.
I have the following questions..
1. I am confused that how come tomcat itself is already a webserver, why would people use it on top of apache http server, which is another web server?
2. To create a web services, (I am thinking of the .net web services that i have done - that once you deploy it with IIS, and you browse to that service, if the function takes 2 parameter, there will be 2 textboxes waiting for you to put data to, then once you post - the xml response will come back...), does java allow front end interface automatically like that in .net? Or you have to code the JSP pages to include those textboxes yourself, and do a manual post to the web services address?
3. Are there any book out there, explains how to use tomcat for webservices? I have looked thru some of the java books that talks about web services, they mainly explain what webservices are, what is xml..etc... and of course, they did talk about the differenct type of messaging format available. (JAX-RPC..etc..)
4. In the java world - how do you use webservices? Is it the same way that i am familiar with? Like, that we have a front end gui, that it will call the web services, pass it a few param, and get the xml result back, and parse it and display / store.. it? Or that is not the correct way to consume the web services in java world?
5. In .net - as long as i have the .net framework sdk, and a IIS - i am good to go. In java - what do i need in order to deploy a web services?? I already have tomcat / jdk / wsdp / IDE - do i have enough to create a simple ws? if so, can you show me a basic tutorial??
based on some reading, i understand that the ws on the service side, needs an SEI implementing java.rmi.remote, and we need another class implementing this SEI. But I would really want to see more example, or downloads, where i can just download / view the whole thing all at once... I googled "java web service", "jax-rpc example"..etc.. most of the return links are from either java.sun.com, or ibm, or some other vendor's web site, explaining the architecture... I really want to look at the code, to get a better understand, what is the relationship between each of these softwares (tomcat, apache http server, axis...)
Any suggestions??
Thanks,
T

I think I can answer your Q1
Apache is very good at serving simple HTML pages
Tomcat is capable of serving active content
So the two complement each other
Or that's how I understand it.

Help on Sun Certified Developer for Java Web Services (CX-310-220) exam

Hi,
I am planing for Sun Certified Developer for Java Web Services (CX-310-220) certification. Can anyone provide me the links for resouces? can anyone provide me books/publications/author best preparation material to score good marks in exam? can anyone provide me the download resources available over internet?
thanks in advance..!!!
regards
gaveesha

yes, that's the only decent book covering most of the exam curiculum (but NOT all of it, check the exam specs versus the book content to know what you are missing).
I'm working on the same material, and boy is it a lot...
Dry, boring stuff most of it.

Java Web Services wrapper and connection management.

We are currently evaluating the use of the SES Java web-services for a custom front end. I've downloaded the sample code and have read through the documentation but I'm confused on a few points.
We will be OSSO protecting the app, so the flow I think I need to use is (on the OracleSearchService object):
*setSoapURL
*proxyLogin
*setSearchUser
*doOracleSearch
(do whatever with results)
From what I can tell each one of these does a separate call into the actual web service. Does this keep a connection open between these calls and if so how do we need to manage our connections in this case. Is there an explicit close method we should be calling? I see that we can get an OracleSoapHTTPConnection from the undocumented getConnection method on OracleSearchService but I'm unsure if we are supposed to interact with it directly.
In a related vein how should we managing our OracleSearchService objects? Should we save an instance for each user in our httpSession, or just create a new instance on each call?
Any insights appreciated,
Jason

No Problem at all
Nomally the Web Service is big different between Web application. or you can build your Web service structure like web application structure. It depends on the web server:
If the Web Server of hosting company has WEB Service framework, you just need know how to deploy your Web service to Web Service framework and How to deploy to Web Server. In this case, you need deploy it two time, one is for Web Server framework and one is for Web Service framework
If the Web Server of hosting company doesn't has WEB Service framework, you need build your own Web Service framework into a web application, then you just need know how to deploy your web application with Web service into Web Server framework

Seeking advice with concept / design of a Java Web Services Application

Hi all,
After a week of searching the internet I'm not sure how which projects, services, etc. I should use to develop my application. Please could someone offer some advice?
Application outline (Java application running on Linux):
1. Wait for an instruction from a Windows WCF application. Instruction contains a list of domain names and one or two other parameters.
2. Perform queries upon those domain names (find if they are registered, etc. - takes 10-20 mins to do complete list)
3. Send back results to WCF application.
Solution 1 (first idea):
1. Create SOAP web service using Java Web Services / Apache to listen for requests. Executes a Java Client Application upon request.
2. Java Client Application performs the queries...
3. Java Client Application sends results to the Windows web service.
Solution 1 Problems:
a) Using 2 applications, they won't be able to share the same memory.
b) The whole process will be slow (having to pass the domain names from the service to application and execute the application each time) - A quick response is critical.
c) Would like is for the whole process to be done under one application, sharing the same memory.
Solution 2:
1. Create a Java Daemon from scratch listening for an incoming SOAP message (no web service like Apache/Tomcat involved).
2. Query the domain names in a new thread inside the Java Daemon
3. Send the results back via SOAP.
Solution 2 Problems:
Cannot find examples of how to create a SOAP service from scratch. E.g. creating a WSDL file based on my application; converting application methods to SOAP-callable methods easily (without writing a framework).
With all the Java tools and projects out there - Java EE, Glassfish Project - there must be a very easy way to achieve this seemingly simple task. Please can someone offer some advice?
Many thanks for reading this.
Richard

You just need an app server like Tomcat.If I'm not wrong, Tomcat is a Servlet container.
Servlets aren't deactivated when they don't receive
any request for some time?
How can I deploy an application to Tomcat in order to
keep it always active?I don't know what you mean. Tomcat is an application that is always running. In what way are the Servlets deactivated?
Apache Axis: http://ws.apache.org/axis/
Yes I'm collecting some info about this... let's see
it!
Finally, to be more clearer... I don't want to start
a new application at each invocation (something like
getting the request, instantiating the necessary
classes and executing them) but to call an already
running app at each invocation (so, getting request
and invoking, in a manner that I don't know, the
running application).The container manages this. If you have data that must remain loaded, you can associate it with the class (use a static modifier.) This will complicate threading, however.
I can use Axis to get the request, but it also grants
me that my app will always be active?I think you are just using the wrong terminology here. What I think you are asking is whether the resources will be loded into memory at all times. If you want to ensure this behavior, you need to associate the data with a class. I'm not 100% positive, but I don't think Tomcat will unload classes in normal circumstances.

Consuming Java Web Service with complex return types

Hi,
I'm consuming a Java Web Service and the return I get in
ColdFusion is a typed Java Object (with custom Java classes like
com.company.project.JavaClass ...)
Within this object I don't get direct accessible properties
as when I'm consuming ColdFusion Web Services, instead I get a
getPROPERTYNAME and setPROPERTYNAME method for each property.
How can I handle this? I don't want to call this methods for
each property (and there are nested objects with arrays of custom
classes below, which would really make this complicated).
What's the best way to cope up with this?
Thanks a lot,
Fritz

The web service is actually the function, not the cfc and you
didn't show a function.
My own opinion is that since webservices by definition should
be available to any calling app (cold fusion, .net, flash, etc),
whatever gets returned from the method should be as universally
recognizable as possible. This generally means text, numbers,
boolean, or xml.
