Do I need a web service for this?

Hi,
Very short question but would like to know what options I have! I want to send an XML file to the server and depending on what�s in that XML file I receive another XML file, which contains the result of my query. The reason for this is because I want to use the same exact backend from different user interfaces (example swing and html).
I believe that this can be done only with XML Web Services, but that is because I have only been exposed to that technology!! Is there some other technology? With XML web services you need to have an Application Browser.
I also thought of maybe using Sockets. A connection would be made with that socket, send the XML and wait for the XML result to arrive.
Anyways which option do you people think is best, and in case of Web Services, which framework / technology do you use?
Thanks and Regards,
Sim085

Hi,
There are really a lot of ways to exchange information (in XML) in a client and server setup. As you have suggested, either socket or web service will do.
In my opinion, I would strongly suggest web service.
Reason as follows:
1) web service uses a standard format of exchanging information. Thus it's always a better approach to stick to standards as it will allow portability.
On the other hand, if socket were to use, you have to define your own set of DTD, which implies what whoever wishes to understand your XML data has to have the DTD. This will not be an issue with web service.
2) As technology is moving towards SOA ( Service Oriented Architecture ), which heavily relies on web service, developing your application with web service will allow your application to leverage on the architecture in the future.
3) web service is language/OS independent.
For implementation of web services, a few possible ways:
- Some developer tools has good tools for webservice, for example, weblogic do has some useful libraries.
-Another useful library is the Axis.
Still, the above may not always be the best choice.
Cheers

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

RFC works but web service for that RFC does not work..weird??

hi all,
I created an RFC enabled function module to create a Sales Order in SAP CRM for both for Varinat Configurable and Normal Materials.
The RFC Works well...if i test it..it creates an order and if i go and check the sales order in CRM GUI. i find that sales order is perfect with the configuration data for the configurable items..
Now i created a Web service for this RFC by calling the Web service creation wizard.
Now i am testing the Web service in SOAMANGER T-code and the sales order is created and weird thing the configuration data is missing for Varinat configurable item..
But i dont encounter this problem if i am testing the RFC directly
What could be wrong...why is my web service behaving weird?
I am dying to find this out..did any body enocunter this situation befor ..please help

Sure Oliver..
I put a break point using external debugger and when i was testing the Web service in SOAMANAGER..
i could then land into ABAP debugger.
There in my RFC i put a logic such that i diffenetiate between VC and Non-VC items and fill the Charateristic Values only if it is aVC item.
I saw that the IF condition was not executing as they suddenly changed the material structure in ECC and it reflected in CRM.
SO i am inputting 18 digits of material no like '000000000000000001' for '1'...but the if condition was checking against 1 =1 so that loop never executed and chara values are not getting filled.
But if i test RFC in se37 ..it works as i am inputting 1...
Since Web service works with XML (WSDL) need to be very careful with the format in which data is inputted and the format in which the logic we wrote in RFC works.
Once again ..thanks to all people who helped me with the answers...

Jessica Sam

JDev: Generating Web Services for Streaming Attachments

Hi,
I am a newbie in this field. I am trying to generate web service code using JDev (10.1.3.3). I have an interface class and the implementation class. When I am trying to generate J2EE Web Service for the implementation class, I am getting the following error:
"The selected class doesn't contain any public method publishable in a web service".
Following is my code:
Interface:
package testing;
import oracle.webservices.attachments.Attachments;
public interface ImageStore extends java.rmi.Remote {
public void storeImage (String name, String desc, Attachments attachments) throws java.rmi.RemoteException;
Impl:
package testing;
import java.io.InputStream;
import javax.activation.DataHandler;
import oracle.webservices.attachments.Attachment;
import oracle.webservices.attachments.Attachments;
import oracle.webservices.attachments.IncomingAttachments;
public class ImageStoreImpl {
public static String storeImage(String name, String desc, Attachments attachments) throws Exception {
IncomingAttachments incomingAtts = attachments.getIncomingAttachments();
if (incomingAtts == null || !incomingAtts.hasNextAttachment())
throw new Exception("Expected request attachments");
Attachment imageAtt = incomingAtts.nextAttachment();
String id = imageAtt.getId();
DataHandler dataHandler = imageAtt.getDataHandler();
InputStream imageStream = dataHandler.getInputStream();
//-- Store image metadata and stream image bytes
if (incomingAtts.hasNextAttachment())
throw new Exception("Expected only one attachment");
return "success";
Can someone please let me know how can I generate the web service for this code using JDev.
Thanks,
J

Hi J,
Why is the concrete class not implementing the ImageStore interface? Anyways, I believe the ImageStoreImpl#storeImage method cannot be static if you want to generate a WS.
Furthermore, you should consider posting your question in the JDev 10G (JDeveloper and ADF forum as this one is for 11G.

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.

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.

Web Service for bulk processing (inserts mostly)

In our case what we have is an interface table that needs to be populated by the web service.
On the web service provider side, we have created EO,VO and AM for this interface table and exposed the AM as a web service using the create and process Operation.
We tested our web service to insert a single row and it works fine. Consumers could do this in a loop to take in multiple rows but that may not be very efficient.
The web service consumer will be calling the web service based on the customer scheduling of the a job. So, at the time of the web service call, number rows to send (from consumers tables) could be any number (100 or 1k or 10k rows) based on the activity on that system.
What will be the most performant way for the consumer to populate data into our SDO and call our web service?
Are there examples that show how we can send bulk data using a web service?
This web service can also be used by 3rd party application (other than our internal applications). They may send data in an XML format. How can that be included in this web service without having to do different things for different types of consumers (internal or external).

I will not comment on "IIS recycle its workers process
". I don't think you have ever said its IIS is the web server used by yourt 3rd paty to host their web service. We (atleast I) don't know wheather your 3rd party's web service is hosted on IIS. It’s some "Web Server"
could be IIS (if its Microsoft based) or Apache or something else.
Come back to your question, when the error says "The request could not be
understood by server due to malformed syntax", when you’re sending the message as expected by 3rd party service, then it has nothing to do with your end, error is returned by your 3rd party. And as you have mentioned you are tracing the
messages thru Fiddler and you see messages are constructed same and fine as expected by your 3rd party. Don't confuse its nothing on your party, either first deployment or last. Check with your 3rd party

How to create web service for database application

Hi everyone
Is it possible to create a web service for an apex database application page which has reports and radio fields and dialog boxes and validations in it. IF it is possible to create, pls help me with example or step by step procedure. I have seen all oracle docs of implementation of Web services in apex but unable to figure out how to get that link of wsdl for an application.
Thanks 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.

Creating web service for bapi and consume in portal.

Hi ,
I am new to Web Services. This is my requirement I need to publish the functionality of bapi as a web service and consume the web service from portal side.
I have followed these steps to create web service.In transaction se80 i have created service definiton and a wsdl file is generated.
When i am exporting that WSDL file and creating a model in a webdynpro project. I am getting the following error. I dont know how to proceed further.Error while loading WSDL.Check error log for more details.
Whether the proxies need to be generated?What is the purpose of it? Where the proxies need to be generated?
Is Process integration needed to use web services?
Kindly guide me how to proceed.
Best Wishes
Idhaya R

the proxy is the object that make possible to use the service; even if service and consumer are on the same host, you need a proxy to use it.

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.

Configuring Web Services for Oracle XML DB

Hi all...
I think I need some help one this subject....
We have a 10G Release 2 Oracle single instance ( not RAC) install on a Linux Redhat v5.3 64 bit server. Are developers are user Visual Studio .Net and wnat to send xml files to a web service so that the xml file (containing data) can call a PL/SQL package (to be written) which will take the data out of the xml input file and insert rows into a prefined table within the instance. Now they have browsed the web and have come upon the following links...
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb22pro.htm#i1026724
Currently, within the database I looked at the schema XDB and have unlocked the account and connected as the user XDB. There are some 680 objects in the following groups...
SQL> select object_type, count(*) from dba_objects where owner='XDB' group by object_type;
OBJECT_TYPE COUNT(*)
SEQUENCE 2
PROCEDURE 5
OPERATOR 8
LOB 334
LIBRARY 12
PACKAGE 20
PACKAGE BODY 17
XML SCHEMA 25
TYPE BODY 5
TRIGGER 12
TABLE 36
INDEX 51
FUNCTION 5
INDEXTYPE 2
VIEW 2
TYPE 144
16 rows selected.
Now in the links above it mentions that the xdbconfig.xml needs to be altered etc. However, I have searched the entire $ORACLE_HOME and there is no file definition of that description.
From a DBA prospective...what do I have to install on the Linux server? I assume from the Oracle Database 10g Companion Products I need to lay down Oracle HTTP Server in a new Oracle home as the first step...or not? Does the HTML DB need to be installed as well?
And for Configuring Web Services for Oracle XML DB...what else has to be installed? And from what product line?
Thanks in Advance....
Cheers
Roegr

Hi Marco...
First of all ...thanks for the reply.
I followed the link and the infor in that web page. However, there were a few things that did not work....
1. The http://localhost:8080/ as is brought up a web page withe the heading as
==========
ORACLE DATABASE 10g EXPRESS EDITION LICENSE AGREEMENT..
==========
The other browser test ftp://localhost:2100/
did not find any page?
2. Then I went onto running (as the sysdba) the pl/sql to enable the ORAWSV Entry Service
however it error out. So I did a describe on DBMS_XDB and the function deleteServlet does not appear
then I had a look and this link to > http://www.liberidu.com/blog/?p=471
was for 11G and the other link > http://docs.oracle.com/cd/B28359_01/appdev.111/b28369.pdf
was for 11G.
However, we are on 10G
=================
SQL> select * from V$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for Linux: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
==================
So is there must be other sql for 10G?

Customizing Web Service for VC 7.10

Hi guys!
I need a big help for the topic "web services and VC".
I read the Scott's blog (The specified item was not found.) and it's great, web services working fine!
But if I would create custom web service (for example to insert google maps on vc model) what can I do?
I know, it's hard to explane all the web services technology and implementation (Java, C#, XML etc.) but if someone know some tutorial or web guides..
Thanks a lot guys!
Edited by: Andrea Davoli on Oct 21, 2008 3:39 PM

Hi Andrea,
I assume that you refer to VC 7.0... otherwise the question should be moved to the VC 7.1 forum...
The following blog contain also a video that show you the process in detail:
How to consume Web Services with Visual Composer 7.0
Also important SAP Notes regarding limitations, structure and pre-requisites are mentioned there.
In the SAP Help Portal you can find information about Web Services created within NetWeaver:
http://help.sap.com/saphelp_erp2005/helpdata/en/db/99c04ba22fe64f96a8651df68eab92/content.htm
Hope this helps,
