Hi Experts,
I have EJB Application with some Java Classes.My Requirement is to Consume Web Service in EJB Application.

Thanks & Regards,

Hi Vijay,
Thanks for the Reply.
Please provide the JAR Files i need to add.
I had tried to consume the web service by using the java class in Java Project ie EJB.
After creating the Project i will import the WSDL file in that Project and create the Client Application.
The Request and Response java class is created by importing the WSDL file.
The Client Java Class is created to access the Request and Response objects.
After this Main class is created and I have run the application to execute the Client Java Class. During this time its shows some error.
The Error Message are:

Consuming Web service : Sample ABAP application

Hi Friends,
I am trying to consume existing web service. I have few questions.
--> Why do we need to create simple ABAP application while consuming Enterprise Service?
--> How this ABAP application will be triggered? Will it be triggered automatically or this is just for testing purpose?
--> After consuming Enterprise Service , which URL my end user can use to execute the functionality ( i.e to craete PO )
Waiting for your expert responses.
Thanks,
Rashmi Jain

Hello,
Please see the responses below:
-->Why do we need to create simple ABAP application while consuming Enterprise Service?
When you created consumer proxy, you have a proxy class autogenerated. The ABAP program is to provide input data and instantiate and call the method within the proxy class.
--> How this ABAP application will be triggered? Will it be triggered automatically or this is just for testing purpose?
The program can be triggered using a Transaction or can be scheduled through batch or event based.
--> After consuming Enterprise Service , which URL my end user can use to execute the functionality ( i.e to craete PO )
The end user does not have to know the URL. This is built into WSDL from which you created consumer proxy.
Thanks,
Venu

Adaptative web service or EJB ?

Hi everybody,
I want consume a web service from a system SAP R/3.
Apparently, we can consume with component EJB ...
What is the difference between a adaptative web service and EJB ?
More security with EJB ?
Thanks
Rodolphe.

Hi,
We use for ejbs when we have to store data in database..
if ejbs r like a medium for data transfer..where session bean contain ur business logic..
u cn use webdynpro interface as well as jsp interface wid ejb..
if u r using ejb u'll have to create an ejb projct first then u'll hav to create java proct which will contain ur wrapper class for fields.later on u'll have to create one application project tht wud b an Ear projct.nw u create a web service for session bean ..aftr doin this all u can test webservice which will b executed for ur business method.
for more security u can use ejb security model :[http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Security.html]
Web services r created for session bean..so that u cn directly access ur methods via url..
for a detailed description of web service go through :- [http://help.sap.com/saphelp_nw04/helpdata/en/d6/f9bc3d52f39d33e10000000a11405a/content.htm]

Web service from ejb

Hi All,
I am new to java web services.
I made web services from ejb with netbeans.
I like only some people to have access to this services with user and pass stored in database.
In other words I need authentication and authorization.
How can I do this?
Regards

Well it depends also on application server you are using.
It depends also on web service stack you are using.
For example here is the hint for glassfish (Metro):

Consuming web service in portal

Hi all,
I had a web service now i want to use it in my portal.
Can anyone help me in this regard.

Hi Lokesh,
To consume a Web service, you can create a deployable or a standalone proxy for the Web service in the SAP NetWeaver Developer Studio using a WSDL document as a basis. This can be done with just a few mouse clicks.
The difference between a deployable and a standalone proxy is that, for a deployable proxy, the application of the Web service client must be deployed on the J2EE engine. A standalone proxy can be executed without the J2EE engine.
The role of the Web service client developer has been created so that Web services can be consumed.
The Web service client developer has the task of integrating a Web service in an application. He or she knows the specific requirements for the Web service and creates the Web service client proxy definition. Afterwards, the developer programs the client application using the service endpoint interface.
Please read through this Step by Step approach for same:-
[Consume WebServices in Portal|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c2188ae5-0601-0010-dd93-c23e381ef41e]
Hope this helps,

Best practice for consuming web services

Hi
we are consuming web service in orchestration by "Add Generated Item".By using this option it creates 1 orch,1xsd file and some bindings.
we have different projects for schemas,maps and orchestration under our solution in visual studio.
Now i need to know that what will be the best practice for consuming web service in orchestration i mean in which project should i use "add generated item" (in orchstration project or in schemas project) coz it generates both 1 orch and 1
schema.
thanks

From a service orientation perspective you should abstract the service artifacts from the other artifacts. Otherwise it will be very difficult to update the service interface without affecting the other artifacts. For example you don't want to have to redeply
your entire application if only one field changes in the service you consume.
So I typically generate the items, remove the unnecessary stuff, and put them in a separate project.
Depending on the control you have over the services you want to consume, it would even be better to create another layer of abstraction. By that I mean create your own interface (schema) and map that one to the one the service exposes. This basically
is only necessary if you consume external services that are beyond your control. By abstracting the interface it exposes, you limit the impact of changes of that interface on the rest of your system. All changes are abstracted behind your own interface.
If you consume internal services, you can probably control the way the interface is defined. In a service oriented world all internal services expose a well known interface, based on the domain objects you have within your organisation.

Windows authentification while consuming web service from ABAP

Hi All,
We are consuming web service from ABAP, we have created client proxy in SE80 and configured logical port in LPCONFIG.
This one was working fine. Now we have added windows user authentification to access this service.
Now when I'm trying to regenerate this proxy in R/3 it is asking for user and password. When I enter these details this one is not working.
If I access this service direcly from internet explorer and I enter same user and password then I would able to access this service.
Could you please let me know how to handle this.
Regards
Vikram

The dialog that is produced by HTTP Destination object of the logical port is designed only for use within Classic Dynpro applications. There is no prompt produced when running in Web Dynpro. If possible assign a generic user within the logical port definition and this will be used automatically by all users.

How to consume web service in Agentry in SMP 3.0

Dear All , I am using web service in Agentry to retrive data but could not able to fetch it . I have made connection with HTTP-XML for consuming webservices. and also give proper information in Agentry.ini files Ex : [HTTPXML-2] name=HTTP-XML Back End authenticationCertificateStore=MY authenticationCertificateStorePassword= authenticationCertificateStorePasswordEncoded=false autoDequote=true ;baseURL=http://localhost:81 baseURL=http://sapes1.sapdevcenter.com:8080/sap/opu/odata/iwbep/gwdemo/ basicAuthenticationPassword=123456 basicAuthenticationPasswordEncoded=false basicAuthenticationUserID=P1466405733 constantsFile=httpxml_sd.ini enableAuthentication=false enablePreviousUserAuthentication=false httpConnectTimeout=300 httpReceiveTimeout=300 httpResolveTimeout=300 httpSendTimeout=300 listenOn= timeout=300 timeZoneName= useSSL=false xmlAllowXSLTScript=true xmlNamespaces= xmlResolveExternals=true xmlValidateOnParse=true for more information i have attached agentry XML screen shot as well . Can you please guide me how to consume web services in Agentry correct way ? Note : Currently i am using standard netweaver demo web services . Thanks & Regards , Kunal Varaiya
Tags edited by: Michael Appleby

The XML Steps URL will be added to the Agentry.ini BaseURL. So you dont' need the full URL on the step.
So when Agentry Runs the step to call the backend it will go:
<BaseURL>/<Step's URL>
This way if you need to change the base URL, IE, going from Dev to QA to Production Server you only need to change the Base, and not go into every step and update it.
URL: This attribute contains the URL to which the Agentry Server will make a request. This value will be appended to the value configured as the base URL for the HTTP-XML system connection. This base URL is configured within the HTTP-XML system connection configuration options for the Agentry Server. Proper use of both this base URL option and the URL entered in the requests of the step definitions can support portability for the application, with the base URL being the implementation-specific portion and the step’s URL being the portion not likely to change for the same back end system from one implementation to the next.

Can i use flex to consume web services?

I am not a Flex developer and before delving into it I want
to be sure that it satisfies my project requirements. Mainly,
consuming web services. the other part of the project are a bunch
of buttons and graphs that constitute any GUI. so I think Flex can
handle this part as good as Flash.
Currently, I am using flash but my current client insists on
using flex. so my question is: can I develop in Flex whatever I can
develop in flash? or are there limitations?

If you are developing applications in Flash, then you will
love Flex. Flex will make you much more productive than Flash for
producing applications of any complexity. You can do at least
"most" of what you can do in Flash, and more. There might be a few
things you can do only in Flash, or more easily in Flex, but your
client has it right. They want Flex and they should want it. Check
out the FB3 help for the WebService, RemoteObject, and HTTPService
components.

How to publish and consume web services in WAS 620?

It appears that Web Service Creation Wizard is only available in WAS 640. We only have WAS 620 installed. Do any of you know what are the steps to publish ABAP function modules as web services, as well as to consume web services?
Thanks,
Angela

Hi Angela,
If you want to expose function modules as web service, you can generate WSDL by running BSP application 'webservicebrowser'. If you want to consume a web service then it is a bit difficult but possible. Look at sample programs (rsvsoap*).
Also look at help document http://help.sap.com/saphelp_47x200/helpdata/en/94/f8c8a2e68811d6b2dc00508b5d5211/frameset.htm

Complete newbie question - Can BI consume web services?

Post Author: Steve Lamont
CA Forum: Data Integration
I am working on a new client site working on integration between a whole slew of systems including CRM, billing, BI etc. The client is architecting a SOA oriented approach to all integration where it make sense. As part of the effort, a new BI database is being built and loaded via some ETL tool. The primary interface to access this new BI data will be business objects (BO). Now, in the current environments, there are multiple, disparate BI systems containing various data. The BO knowledge person (and he is not a business object employee) on this site is claiming that to access these other BI databases, he wants to do it by sending out requests via service calls. I fully understand that BO itself can be set up to be a service provider and provide services for other consumers to take advantage of, but how does BO itself consume services provided by other applications?
Obviously I don't fully understand BO, but my initial inclination is that this approach is wrong. If data is required from these other BI source, wouldn't they be configured as data sources within business objects? This BO guy claims that calling web services is more efficient that direct peer-to-peer calls via the database drivers.
Can any share some comments on this situation?

You posted your question to the wrong forum, please try to post it to one of the subforums in "Enterprise Reporting, Query & Analysis".
This forum is about Data Integrator, Business Objects ETL tool.
I'll try to answer your question anyway with my reporting background From what I know, YES we can consume web services in reports (Crystal reports), but for larger volumes of data a direct access to the database would be faster. A webservice approach might make sense if the webservice implements some business logic (semantic layer) which would be easier then to go directly to the tables.
And just for the record : also Data Integrator can consumer web services...

How to deploy a web service on Oracle Application Server 10.1.2.0.2?

Hi everyone,
I followed the instructions of the following link to create a web service using jDeveloper 10.1.3.1.0 on Oracle Application Server 10.1.2.0.2. [http://st-curriculum.oracle.com/obe/jdev/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm#t1]
The web service created was deployed & used with no errors on the standalone OC4J instance.
But my goal is to deploy my web service on Oracle Application Server 10.1.2.0.2.
So after several attempts, I was able to deploy it on the Oracle Application Server 10.1.2.0.2 but unfortunately I didn't know the URL needed to use the web service.
I tried the following link (http://192.168.0.91:18100/JavaWebService-GetDates-context-root/GetDatesWSSoapHttpPort) but also didn't work :(
I also tried converting to J2EE 1.3 and still not knowing how to access the web service.
Please advice with a solution.
Thanks in advance.
Lana

Thanks everyone for your help :)
The problem turned out to be that Oracle application server 10.1.2 is unlike the others servers, it uses 2 ports:
- port (19100) is dedicated for the console.
- port (7779) is to view your applications.
So the URL needed turned out to be "http://acteos-109.beirut.acteos:7779/beanTest" instead of "http://acteos-109.beirut.acteos:18100/beanTest"
Hope this info is useful
