Web Services for a State Machine Based VI

Hello,
I am new to the Web Services approach but so far I have managed to build a simple VI which is used with Web Services to display a Graph and make some simple calculations.
However, I have a more complex application which uses a State Machine architecture to command some circuitry using the NI USB 6211 device. This program includes different states and all the action takes place inside a while loop. This loop uses shift registers to pass the states arround (the JKI State Machine).
My question is: Could such a program be used with the Web Services without modifying this structure?
In the programs that I have tried, if I place the execution inside a While structure then I get no result with the Web Services.
An example of a simple program which includes a while loop and the Web Services approach would be helpful, if possible.
Thank you in advance.

Hello again,
I was trying to do what Nathand indicated.
1. "Put a functional global in it that stores whatever value you want to be queried over the web,"
So I opened a new Project and added the Index.vi just to generate the numbers continuously. This VI writes to a global variable entitled "GlobalOutput.vi".
This works as I have attached the jpg image.
2. "and make that VI accessible through VI server."
This I am not so sure I did correctly. I opened the Tools->Options->VI Server, and here at the section Exported VIs, I added the GlobalOutput.vi. I have attached the image.
3. "Then, in your web services VI, open a VI server connection to that functional global and run it, by reference, to obtain the value stored there."
Now I have created another VI, called ServerConnection.vi which runs the GlobalOutput.vi. I have attached the image with the error I get. Something is wrong in what I am doing. In the end I thought that I would create a Web Service for this last vi and basically be able to read the global variable.
As I understand it, you have a VI which runs locally, in a while loop and updates some global variables. Then another vi reads the values of those global variables.
It is this last vi that you should create a web service and interogate to find out the values of those variables. What am I missing?
Thank you in advance.

Create a Web Service for Exchange with form based authentication ?

I want to create a Web Service in Apex that can create appointments in my exchange calendar. Exchange is offering web services for that.
When i try to create the web service reference in Apex i provide the URL and my Exchange login, but it is failing.
The exchange guys told me, that there is a ISA Server running where i need to authenticate through a form.
Does anyone know, how i can implement a webservice in Apex, when the access to the wsdl url needs login through a form ?
Or : what other types of authentication does Apex know ? What possibilities do i have ?
Thanks for answers.
Bernd

Hi
Presume you've already found this information, but in case not ....
Exchange 2007 provides out of the box web services, see
http://msdn.microsoft.com/en-us/library/bb408417.aspx
As a disclaimer - neither myself of the team I work with have tried to use these web services within APEX.

Standard Web service for Plant maintenance

Hi Gurus,

Hi,
This is the mail which i got from Client.
We have a prospect wanting to see a proof of concept (and pay for it) of SAP -GIS integration using web services. No specific requirement. Fetch a bunch of work orders from SAP using web service and display on a map - can be the POC.
Please review the attached doc. Figure out whether any standard web service is available, if not a BAPI can be converted to web service quickly.
Attchment contains Utilizing State oriented Communications
for Web Services based on BAPI With Microsoft Visual Studio
2005.U can check it in Google with the same name.
They just asked about is there any Standard web services available for Plant maintenance.

Web Services for Oracle 8i

Is there any means for the Oracle 8i Platform to implement a Webservice to
access Business Logic in stored precedures?
We were evaluating IONA's XML Collaboration Suite and their Oracle Adaptor
but we are not satisfied with the level of control the adaptor provides.
Do you have any suggestions?
Best regards,
Andreas

Yes, you can publish stored procedures as Web services. Two approaches:
1. Check out the new Web services sample that came out the other day, example two where SQLJ is used to wrap a Java class as a stored procedure, the connection is then wired into the generated class and finally it is published as a Java Web service using Oracle9i JDeveloper 9.0.2. See:
http://otn.oracle.com/sample_code/tech/java/web_services/
and look at the Tax Calculator viewlet/code.
2. This is essentially the same way that the OC4J PL/SQL Web service samples work too (using SQLJ to generate a Java PL/SQL proxy), but the OC4J sample (url below), provides a more parametric way to pass the connection information to the proxy by using a parameter in the web.xml file. Check out:
http://download.oracle.com/otn/java/oc4j/how-to-web-services.zip
See the readme and work with the sample in plsqlws.zip
This one is a both better and worse from a developers perspective compared to the first Oracle9i Jdeveloper oriented example. The good part, depending on your perspective, is that it is all command line based (some people like this, some people don't) and uses the longer term approach to publishing stored procedures as Web services for Oracle9iAS with the parameters passed in via the web.xml. The bad part is the example is a little hard to follow because many of the pieces are already created for you rather than explaining how they were created. The first example at least shows pretty much all the steps but doesn't quite elegantly solve the connection problem that the OC4J sample does.
In July/August, Oracle9i JDeveloper will be updated to publish stored procedures using the Oracle9iAS infrastructure (basically the web.xml fix) ... although once you understand it, it is fairly easy to manually do it inside of JDeveloper.
Hope this gets you going.
Mike.

Is there any dummy web service for study purpose?

Hi Devs,
One of my friend want to use a java web service, as he is not in my domain I am not able to give him web service developed on my machine. He is doing research on how sharepoint can use Java web service. Any simple java service doing addition calculation will do for him. But the thing is that we both are not able to find a dummy or study purpose web service on net. It will be great help if anyone has any link to such web service.
Looking forward to you help.

Thanks Cindy for your kind help :-) !!!
We also need a dummy java web service which is already existing somewhere on internet, uploaded for study purpose. This web service will be used for test purpose in application. A simple java web service doing addition or calculation will do.
Please help

After i installed updates for my mac mini server, the web services for the server app wont start, it gives an error massage: "Error Reading Settings"

After i installed updates for my mac mini server, the web services for the server app wont start, it gives an error massage: "Error Reading Settings"
The system logs reads:
Mar 29 22:06:25 server servermgrd[82]: servermgr_web: Error Domain=XSServerFoundationErrorDomain Code=4 "Failed to read settings: Exception:
          undefined method `downcase' for nil:NilClass
          ." UserInfo=0x7fc547901080 {NSLocalizedDescription=Failed to read settings: Exception:
          undefined method `downcase' for nil:NilClass

To check the local network for some of the common configuration problems, launch Terminal.app and issue the following diagnostic command:
sudo changeip -checkhostname
That'll report some local configuration information and then either no errors detected and no changes required, or it'll point to whatever configuration errors or issues it might detect. That doesn't catch everything, but it catches the common errors.
FWIW, 192.168.0.0/24 and 192.168.1.0/24 are poor choices for the local network, as VPNs are based on IP routing and IP routing gets tangled when the same subnet is used on both ends of the VPN. 192.168.0.0/24 and 192.168.1.0/24 are near ubiquitous in home networks and coffee shops.

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

Test web service for a function module

Thanks Venu for your input.
Unfortunetly we do not have Java stack on our development system. You said we can test it by SOAP UI tool. Where do I see the WSDL file for the service?
I used WSDL from SE80 --> Service --> WSDL tab, but SOAP UI does not accept this format ?
What are the other ways I can test this web service? I think about SAP PI, importing RFC & creating web service or creating ABAP proxies... Which is the best way to go forward in case you do not have Java stck.

Issue in creating web service for a ABAP Function Module

Hi,
now i'm learning how to create web service for a ABAP Function Module. I used the following steps.
1. select the Function Module, named "zws_test".
2. in the context menu, select "create->proxy object". so we enter into wizard.
3. in the wizard, press the radio button "Service Provider".
4. in the next page, press the radio button "Existing ABAP Objects(Inside Out)".
5. In the next page, Enter the "zws_test_prvider" as Service Definition and select "Function Module" as Endpoint Type.
6. in the next page, enter "zws_test" as Function Module and mark the "Mapping der Namen" button
7. in the next page,select "PRF_DT_IF_SEC_LOW" as Profile and mark "Deploy Service".
8. Save in the local package.
9. then it will pop up a window with title "WSDL Source". i selected "URL/HTTP Destination" and press "OK".
10.in the next page, i enter the URL as "http://hostname:portnumber/", and press "OK".
11. then it will pop up a window with title "Display logs". A record with error message "HTTP error(return code 404, message "Not found")" appears.
12. i press "ok" and a service provider with name "zws_test_prvider" appears in my local package.
13. i use "zws_test_prvider"'s URL to create a service consumer "ZCO_WS_TEST_CONSUMER" and logic portal "LP1".
14. But when i test my service consumer "ZCO_WS_TEST_CONSUMER", it will throw an exception "cx_ai_system_fault" with errortext "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/".
15. I use t-code SM59 to test connection and get the following info.
      Status HTTP Response     200
      Status Text                      OK
      Duration Test Call             328 ms.
who can give me the reasons about item 11 and 14, and explain me how to create service provider and service consumer for a Function Module.
Thanks in advance

XI for create web servicies for SAP R/3 4.6C

Hi All,
we are implementing PM (Plant Management) module of SAP R/3 4.6C and we have the necessity to create web services for some PM functionalities. Infact we need to integrate our SAP R/3 4.6C with other applications (non-SAP) through TIBCO (it's mandatory). So we think to use SAP XI. Moreover our users don't want to use SAP GUI for the accessing to the PM functionalities but they want an UI more friendly. So we think to use SAP EP.
Which is your opinion about this architectural scenario? Is it possible to fulfil the requirement of our business users with a more simple architectural solution (for example with WEB DYNPRO)?
Many thanks in advance for your collaboration.
Regards,
Bob

Infact we need to integrate our SAP R/3 4.6C with other applications (non-SAP) through TIBCO (it's mandatory). So we think to use SAP XI.
TIBCO is another middleware. So once you expose your R/3 functionalities as web service, you may directly use TIBCO to integrate and XI won't be required at all.
Moreover our users don't want to use SAP GUI for the accessing to the PM functionalities but they want an UI more friendly.
WebDynpro application would provide you an easy GUI and could act as Soap client as well to send data.

Prateek

Creating Web service for PL/SQL Procedure with Complex Data Types

I need to created web service for PL/SQL Procedure with Complex Data types like table of records as parameters, how do we map the pl/sql table type parameters with web service, how to go about these?

Hello,
When you are creating a service from a Stored Procedure, the OracleAS WS tools will create necessary Java and PL wrapper code to handle the complex types (table of record) properly and make them compatible with XML format for SOAP messages.
So what you should do is to use JDeveloper or WSA command line, to create a service from your store procedure and you will see that most of the work will be done for you.
You can find more information in the:
- Developing Web Services that Expose Database Resources
chapter of the Web Service Developer's guide.

How to write a web service for uploading a file

Hi all,
I want to write a web service for uploading a file to some specified folder under application server, how to do that? Thanks

I believe the "difference" that you're seeing is that one web service is "RPC" style (The Hello World example) and one web service is "Document" style (The WSDL you have downloaded).
Document-style web service methods always have one element as a parameter, and this parameter manifests itself as a SOAPElement in the service interface.
RPC-style web services are true "remote procedure calls", and are more functional in nature, in that they accept multiple parameters. JAX-RPC will bind these parameters to generated Java types.

Creating RESTful Web Service for BLOB retrieval

Hi,
Just got RESTful web services working in Apex 4.2.1 with new Listener 2.1.
I have now been asked to create a RESTful web service by which photos in BLOB column can be retrieved upon providing the ID for that photo. Can this be done using the Creating RESTful Service Module of Apex 4.2.1? Looking at the Apex 4.2 documentation, I would assume this can be done, but has anyone used this with BLOB data?
Thanks,
Pat

Hi Pat,
Yes this can be done using RESTful Services - you just need to ensure the query used is in the required format. To obtain a BLOB for a given ID, you would need create a Resource template and handler with the following settings:
Resource Template Settings:
URI template: emppic/{id}
Resource Handler Settings:
Source query: select mimetype, product_image from demo_product_info where product_id = :id..where the format of the SQL query is SELECT 'content_type', blob_column FROM . . ., as mentioned in Rick Greenwald's Cloud White paper "RESTful Web Services for the Oracle Database Cloud", under the "SQL Source Type" section (see www.oracle.com/technetwork/database/database-cloud/public/restful-wp-1844130.pdf ):
where 'content_type' is a string passed to the browser to be used to identify the incoming data, and the column to identify the source of the data being sent back. This data is sent back untouched by the Oracle Database Cloud Service. The Media Resource Source Type is typically used for media objects, such as images, where the data will be directly handled by the recipient making the call.The MIMETYPE column in the sample query above holds the necessary setting for the 'content_type' i.e. 'image/jpeg'. The value of ID is then passed in as a parameter when calling the service e.g. emppic/1234. The item level help text would be more helpful if it included additional information, and this is something we intend on addressing in a future release.
I hope this example helps.
Regards,
Hilary
