Project Suggestions Topics on Web Services.

Hi,
I need someones help in thinking out the topic for my class project on Web Services. I need to write an application (only a client for existing Web Service or both Web Service Server and Client) and I got free hand on figure out the topic (problem) my self. I have never written anything using any Web Service technologies so I haven't got a clue what to code . If one has an idea to share I would appreciate as I'm in a dead spot and deadlines are coming ... It doesnt have to be anything fancy, mind blowing nor anything hardcore to code. I always have problems in figure out something this is why I decided to as for help ...
So again if anyone has some idea which would be good the topic which is "Write an application using Web Services technologies" an would like to explain it in few words I would be greateful.
Thank you in advance.

aur is soon to have JSON support http://archlinux.org/pipermail/tur-user … 06131.html -- read on
maybe it'd be ok for you to hack on that

One project with two different web services styles (JAX-RPC and JAX-WS)

Hi theres,
how come the same project doesn't support two different web services styles?
First time I create a web service proxy using the wizard, the second step is to choose between JAX-RPC and JAX-WS. After that, this step is removed from the wizard and all subsquent web services are assumed to be the same style as the first one.
Can someone explain me why?
thanks in advance,
Manuel Leiria

Hi,
yes, I think to remember that there is support for a single style only. If you need another one too then you create a new project.

Receive asynchronous message from JMS topic over web service

Hi,
I have a JMS topic and I want to expose it as a web service so that clients can
make durable subcription to the topic and receive messages asynchronously. What
is the best way of doing this ? Is there a portable (to other containers) way
of do this ? If not, is there a web logic specific way of doing this ?
Thanks,
Siva

So you expect clients to be receiving SOAP messages over HTTP? In this
case, the clients are really servers that are capable of servicing SOAP
requests, correct? And how about the senders: are they also using
SOAP/HTTP to send messages that are delivered to the receivers?
It should be possible to write this yourself using JMS not as the
transport, but as a mechanism for distributing the message to a set of
clients. You'll need to implement a Web Service for publishing to a
topic, an operation for registering an end point to recieve messages,
and an MDB (or other form of JMS subscriber) executing on the server to
relay the message to the end point.

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information

JMS with web service ,project ?

I would like to come up with a masters project on JMS and Web Service. I need to convince my lecturer whether this thesis in JMS is competative enough with latest technology.I need some advice and explaination about JMS and popular thesis topic that can make up.This has to be in a matter of problem solving if possible.Hope someone can help.This project may not to be a very huge project.
Pls give some good idea's .

Hi,
Web Services is fine for B2B, and JMs is fine for Legacy system communication.
Web Services + JMS is a good way in order to cooperate microsystem and mainframes.

Project Server 2010 Web services access with Client Certificate Authentication

We switched our SharePoint/Project Server 2010 farm to use client certificate authentication with Active Directory Federation Services (AD FS) 2.0, which is working without issue. We have some administrative Project Server Interface (PSI)
web service applications that no longer connect to server with the new authentication configuration. Our custom applications are using the WCF interface to access the public web services.
Please let us know if it is possible to authenticate with AD FS 2.0 and then call
Project Server web services. Any help or coding examples would be greatly appreciated.

what is the error occurred when the custom PSI app connects?
can you upload the ULS logs here for research?
What is the user account format you specified in the code for authentication?
For proper authorization, the “user logon account” in PWA for the user needs to be changed from domain\username to the claims token (e.g.
'I:0#.w|mybusinessdomain\ewmccarty').
It requires you to manually call the UpnLogon method of
“Claims to Windows Token Service”. if (Thread.CurrentPrincipal.Identity is ClaimsIdentity)
{ var identity = (ClaimsIdentity)Thread.CurrentPrincipal.Identity; }
if (Thread.CurrentPrincipal.Identity is ClaimsIdentity)
var identity = (ClaimsIdentity)Thread.CurrentPrincipal.Identity;
Than you need to extract UPN-Claim from the identity.
Upload the verbose log if possible.
Did you see this?

Unable to open connection to MS Access 2013 .accdb file Under WCF Web Service Project Using Windows 8.1 64bit

I am encountering the following error when trying to connect to an Access 2013 database:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
I have Visual Studio 2013 SP3 running on Windows 8.1 64bit OS which also has Office 2013 installed (which includes MS Access 2013). My project is a WCF web service using .NET Framework 4.5.1 using any cpu as target. I have tried reluctantly
to install the older drivers as described by in the below article:
https://social.msdn.microsoft.com/Forums/en-US/1d5c04c7-157f-4955-a14b-41d912d50a64/how-to-fix-error-the-microsoftaceoledb120-provider-is-not-registered-on-the-local-machine?forum=vstsdb
and also went through the "Add Data Source" wizard in the Project menu to have the connect string automatically built. Even with the automatically built connect string I can not connect to the .accdb file from within my WCF web service.
What's odd is if I use the Database Explorer in Visual Studio it has no problem connecting the my Access file. I inspected the connect string and tried to use it as well but still get the same error. Even stranger is that I have no problem connecting
to the Access DB in an ASP.NET project on the same PC. I am also able to connect to the Access file using a simple Windows Forms application. So I'm wondering if it has something to do with trying to connect to the Access file from a WCF web service
project.
What I'd like to know is if anyone has been able to get this to work in an environment as I described above as a 64bit WCF web service project? I tried to switch my project to 32bit but when I do I get a different error which reads:
System.BadImageFormatException: Could not load file or assembly 'file:
Almost to the point of trying to get this web service project done with SQL Express but would like to know if it can be done with MS Access 2013. Any information anyone can provide to help me get past this issue is greatly appreciated. Thanks.

Have you installed the 64-bit Access driver on your machine? See
Data Source Names and 64-Bit Operating Systems for the differences in odbcad32. Call %SystemRoot%\system32\odbcad32.exe to check the drivers.
How do you host your service? Stand-alone or IIS or embedded to another application? Keep in mind that IIS7 runs it in its application pool which is defaullt 64bit. Thus the bad image exception, when compiling your service as 32bit.
When you need the Access database for your service to store informtation, then I would switch to SQL Server (Express) or XML files depending on your actual needs.
Also check whether your account under which your service is run has the necessary NTFS file permissions on the access file and the folder. This is getting even more complex when it's a remote folder.

Unable to call a web service from BPEL Project

I am running my BPEL PM on Windows XP SP3. The platform is weblogic 9.2, SOA 10.1.3.1.
I created a simple BPEL project to call a web service and when I run the project from BPELConsole I getting the following error:

I am able to call this web service from soapUI client.
Any help or hint is appreciated.

I have had this issue before when calling a .NET service, it was firewall related. I didn't actually make the fix so I can't tell you exactly how it was fixed on the server. I hope this info makes sense as this this the info I got from the IT boys
I’ve install this tool on your computer:
http://www.microsoft.com/downloads/details.aspx?FamilyID=05C2C932-B15A-4990-B525-66380743DA89&displaylang=en
which does that:
Firewall Client for ISA Server can be optionally installed on client computers protected by Microsoft ISA Server. Firewall Client for ISA Server provides enhanced security, application support, and access control for client computers. It provides authentication for Winsock applications that use TCP and UDP, supports complex secondary protocols, and supplies user and application information to the ISA Server logs.
When a client computer running Firewall Client for ISA Server makes a request, the destination is evaluated by the Firewall Client software, and external requests are directed to the ISA Server computer for handling. No specific routing infrastructure is required. Firewall Client sends user information transparently with each request, enabling you to create a firewall policy on the ISA Server computer with rules that use the authentication credentials presented by the client. ISA Server allows you to configure automatic discovery for Firewall client computers, using a WPAD entry in DNS or DHCP to obtain correct Web proxy settings for clients, depending on their location.
and I’ve added a exception in IE to the tools-lan settings-advanced-exceptions to be creditworks.* Did this by modifying the GPO that applies to your account, so all the users in National Office should have that exception.
hope you can use this.

How to create web service for a Java class in SAP NetWeaver Studio

hi all,
i am using SAP Netweaver Developer Studio.have created a normal java project and i want to create web service for one of the classes in this project. i used the Web Service Creation Wizard to create a web service for this class. but it says there's no methods available for VI. all my methods in this class are public, what should i do?

Hi,
I guess there are other ways. But this is an easy way, if you find the right wizards.
Besides this it is good practise to define interface methods so that session bean implement these interface methods, and thus seperate the interface from the implementation.
In this approach you will need 3 projects:
An enterprise application project (will contain EJB Module)
An EJB Module project (will contain session bean)
A Java project (contains code that implements the session bean methods)
In my previous post I suggested to use a J2EE web mudule project. This was a mistake, it should be EJB module.
But it should be possible to do it in another way. It is up to you.
Good luck, Roelof

Web Service URL length limits, LV2013 vs LV2012

(* CROSS POST: http://lavag.org/topic/18435-web-service-url-length-limits-lv2013-vs-lv2012/ *)
(* Please reply in this forum. I have marked the other thread to put replies here. *)
Has anyone noticed a reduction to the limit on URL length for Web Services between LV versions 2012 and 2013?
Under LV2012, a RESTful web service appears to accept URL with lengths at least as long as 4096 characters. With LV2013, the max URL length appears to be 511 characters for both RESTful and Project Item web services. Unfortunately for me the project I just converted trips over this issue. My goal with posting this query to here is to improve my understanding of this limitation before I decide how best to modify my code. Certainly using POST rather than GET with a long URL is an option, but again, I'm looking to understand the change in limitation before I choose a solution.
To illustrate I have attached three mostly identical projects which demonstrate the issue. In each case the project contains a webservice consisting of a single VI, "ComputeLength", which takes a String as an input parameter and which outputs the length of the string. The three projects are as follows.
1. LV2012 RESTful web service.
2. LV2013 RESTful web service.
3. LV2013 Project item web service.
The web service contains a single VI. For the RESTful examples, the web service is started by selecting Deploy from the Build specification right click menu. For the Project Item example, the web service is started by selecting Start from the MyComputer/WebService right click menu. The use of this example is demonstrated with the following URL:
(note that the port is 8080 for the two RESTful examples and is 8001 for the Project item web service if used in Debug mode, which is the default for the above instruction.)
http://localhost:8080/webservice/computelength?string=1234567890
And the output looks like this.
<Response>
<Terminal>
<Name>StringLength</Name>
<Value>10</Value>
</Terminal>
</Response>
To see the issue, extend the string parameter such that the URL contains more than 511 characters beyond the port number. For example something like this, http://localhost:8080/webservice/computelength?string=1234567890123456789012345678901234567890....(keep repeating)
For the LV2012 example the string parameter may be at least as long as 4000 characters, which I've demonstrated using Chrome as my browser. For both of the LV2013 examples the URL is limited to 511 characters after the localhost and the port number.
Anyone know whether this is a bug or this is an intentional design change? How about whether the URL length limit is configurable?
I am also consulting NI tech support and will report back their response.
Any advice appreciated.
Thanks,
Martin

Solution found. Apparently starting in LV 2013, there is a default limit of 512 to the URL length. The default limit may be overridden as described below.
Martin
This is Brian in Applications Engineering from National Instruments. I am following up regarding the 511 character limit in your Web Service HTTP request following the port number. After some research I've figured out that the issue is related to a default web server setting called "LimitUri," which limits the maximum length of a URL. The default setting is 512 characters which is why we are seeing this issue.
There are multiple ways of changing the URL length limit depending on how you are using your web service. If you are publishing the web service using the Application Web Server then modify "C:\Program Files (x86)\National Instruments\Shared\NI WebServer\NIWebAppServer.conf" and add "LimitUri 4096" to the end of the file without the quotes.
If you are running the Debug Web Server by just clicking start on the web service then modify "C:\Program Files (x86)\National Instruments\LabVIEW 2013\resource\webserver\niwsdebugserver.conf" and add "LimitUri 4096" to the end of the file without the quotes.

Java web services basic question

Hi all,
I'm new to web services programming, and I'm having trouble getting my head around a few conceptual ideas about web services. I'm in a graduate class right now where our project needs to use web services to create a distributed system. We're using Axis2 and jUDDI for development.
In terms of distributed systems, I am a CORBA programmer, and so when I'm given a problem, my mind immediately goes to how I would implement it in CORBA. Web services seem similar (the WSDL is like an IDL, an jUDDI is like the CORBA naming service, etc) but I'm having difficulty figuring out how to instantiate two (or more) web services that implement the same interface.
From the simple 'hello, world' web services I've done, I have created a java class, compiled it, packaged it into a .aar, and deployed tye aar using Axis2 on Tomcat, my application server (which somehow creates the WSDL file - I'm not exactly sure how that happens either). From there, it's simple to write a client to connect to the web service, which seems to always be running in the application server.
Now, for the system I'm working on, we need to have multiple 'instances' of a service. For example (note this isn't the actual project assignment), say there is a 'GPS_Service' web service with a simple interface with two methods: getLocation(), and setLocation(point p). In my 'application', I want to deploy 15 'instances' of GPS_Service, and set and view their location independently.
Here's where my lack of knowledge hurts. From my point of view, I would need 15 different java classes (i.e. GPS_Service0, GPS_Service1, etc) and 15 different .aar files. Each .aar file would go into the application server, and I would access each service at a different web address.
In CORBA, this is much easier. Classes implement a CORBA interface, and your 'main' method can instantiate as many 'GPS_Service' objects as it wants. This seems to be because CORBA doesn't have an 'application' server where the object is always running.
Does anyone have any suggestions for me, or does anyone have an example of what I'm trying to do?
Thanks,
Eric

I forgot to answer your question.
You have to consume the webservice :
http://gerardnico.com/wiki/ide/eclipse/eclipse_how_to_consume_a_webservice_with_wtp
It will create for you the package
com.siebel.analytics.web.soap.v5
See my example. I think it's enough complete.

Cannot create web service: target server does not support JAXRPC

I created a web application project, with bundled Tomcat5.5 as server. When I tried to create a web service (right click project name, select New->web service), I got a error message saying "The current target server for this project does not support JAXRPC so no web service can be created". I tried adding jaxrpc lib to the project, it didn't work. I also tried to add jaxrpc jar to Tomcat using Server Manager, it didn't work either.
Did I miss anything, during installation or project setup...? Is there a way to make the problem go away?
Many thanks for your help.

Can you please try the bundled Sun Java System Application Server as the target server for the project? (You can change the target server from the project's properties dialog, in the 'Run' category, using the 'server' drop-down box).
I also noticed the same error message as you when i set my target server to bundled tomcat; when i changes the server to SJSA, the message went away.
When i searched in the IDE Help (by selecting Help | Help Contents menu item, switching to 'search' tab in the help window , typing 'jwsdp tomcat' in the Find box and pressing enter), I came across the topic "Using JWSDP 1.6 on the Tomcat Web Server". This topic explains how to install Web Services Developer Pack on tomcat server. I could be wrong but I think this perhaps needs to be installed manually...

List of Web Services available in NW'04

Hi Raja,
Thanks for the reply. Can you please tell me ON which version ABAP engine this transaction exists. I have one link from EP which takes me directly into Web services Repository. Is it the same which you are talking about. Plz tell me from which SAP Release onwards SAP is providing ESR and how can i browse these. On my IDES transaction WSADMIN doesnt exists. Awaiting.

Using WebCenter Spaces Web Service API through JDeveloper's Data Control

Hi,
I'm trying to access WebCenter Spaces Web Service API (located at http://host:port/webcenter/SpacesWebService)
using JDeveloper's Web Center Data Control.
I created a data control in my portal project using JDeveloper's Web Service Data Control wizard.
I also created and configured key stores (jps-config.xml) at both sides (spaces server and my portal client).
How I created a data control:
* First I entered the name and the URL (http://host:port/webcenter/SpacesWebService?WSDL)
* Then I entered HTTP basic authentication details (user name and password)
* After that I drag-and-drop the getGroupSpaces() method from the data control to a .jspx page as a ADF read-only table.
* Then ran my portal project and navigated to this .jspx page and it worked. List of group spaces appeared well on that page.
The problem is that I got only public group spaces and group spaces created by the user I entered on HTTP basic authentication details.
I makes no sense to enter some static user details in a web service client (or a data control).
So the question is; can I use identity propagation to get only group spaces created by the same user which I logged in my portal?

Hi,
You generally get NameError when you are executing the createCred/updateCred from a incorrect location. Are you using the wlst from oracle_common\common\bin?
Also, In your steps I don't see what you did to populate the walllet at JDeveloper end after your updateCred failed. This is a required step. Use the wlst from the location emntioned above and you should be able to proceed.
Thanks,
Vishal
