Any existing BAPI that can be wrapped and exposed as a web service ???

Hi ,
I am designing PI Collaboration Platform and that all about Monitoring across SAP ECC, SAP PI and Non-SAP applications.
BUSINESS CASE: Some clients are looking for a solution that allows there management some visibility into the end-to-end aspect of processes, we will limit our discussion to SAP ECC and PI.
SOLUTION: BAM ultimately helps solve this problem at an enterprise level - however that is a heavy investment for most organizations - is there an alternative that we can provide ? Example a generic web service that can be invoked from a 3rd party tool to provide reports.
We do have solution :
We can configure Proxy adapter and can write Java web service to invoke a method to extract the data from ECC and one or more report generating methods based on the standard ( like PDF,EXCEL etc)
but we are still looking for an existing BAPI that can be wrapped and exposed as a web service ????
Need solution for the above ?

Hi Sanjay,
Yes BAM has a bigger take, if you are looking for PI monitoring reports then please have a look at the following blogs which might
give you some insight.this basically deal with reading data from SXMB_MONI tables.

http://wiki.sdn.sap.com/wiki/display/Snippets/PIMonitoringFunctionality-FetchingDatafromSXMB_MONIStandardTables-PartI
i dont think there is any BAPI as such atleast wrt to PI.

Authentication while consuming a BAPI exposed as a web service

Hi all,
This is the scenario - I am consuming a web service in my web dynpro application. The web service is nothing but a BAPI which is exposed as WS.
My query - how do I achieve authentication from the web dynpro application to the web service using SAP Logon ticket?
In NWDS, after I import the Web service and create a WS model, there's a node called 'Logical Ports'. In that node, I've set the authentication type in the security tab as 'Use SAP Logon Ticket'. But that doesn't work.Is there any other configuration to be made?
Also, immaterial of the type of authentication I specify(even if I specify 'no authentication'), only if I set the userid & password for accessing the backend in my code, does my application work!! Otherwise, it throws an authorization error!!
I'm struck with this issue for quite sometime. Have gone through help.sap links and also SAP docs. Most of the docs deal with either security for an RFC model or for a Web service project(EJB). I am not able to find a solution for my case.
Can somebody help me solve this?
Points assured.
Thanks & regards,

Proxy exposed as a web service but cannot be reached

Hello,
I've exposed a server proxy as a web service and it looks OK in WSADMIN and WSCONFIG, also a service is created in ICM. But when I test the service, the browser page that opens cannot be reached and if I try to send a message to the service, I get the error HTTP Error: Could not POST file.
What might be the cause?
Thanks,
Gökhan

I had an error in my implementation.. nothing serious.

Exposing a J2EE Web Service ... How to configure Date and Time parameters?

I'm exposing a class that actually utilizes a Toplink Facade to perform transactions with a database. One of the parameters one of the service methods accepts is of type java.util.Date which translates into an XML type dateTime. I also have two fields that are currently being accepted as Strings and then parsed to determine the time. Is there some way that I can define the types in the WSDL to be a "simple" date format (i.e. YYYY-MM-DD) and time format (i.e. HH:MM:SS) and have them translated automatically via the java-xml mapping file generated with the web service?
Thanks!
Edited by: shaunduncan on Mar 23, 2009 7:12 AM

I've found a workaround using Strings and parsing using both manual parsing and SimpleDateFormat.
Ex:
Dates: YYYY-MM-DD Format
Times: HH:MM:SS Format

Exposing RFC as Web Service in XI

Hi,
I want to expose RFC of an external R/3 System as a Web Service in XI. I do not have much Idea about XI.
It will be great help If I can get some documentation on step by step tutorial of the same type of Scenario.
Thanks
Naresh

Technically it can be done though.
I have done it in Xi 3.0. You create a synchronous interface in XI. Generate the WSDL from the repository. The calling systems consumes it using SOAP. The destination system does not need to be WAS. It can be 4.6C, or even non-Sap.
I have tested this for Asynch postings into 4.6C and it works fine so it should work for synch also however, XI has some problems with the bindings in the WSDL at this stage. You may need to manipulate the WSDL generated in the repository to create SOAP bindings. I understand the problem is being resolved in SP4....
If you do not know about WSDL bindings go to: http://www.w3schools.com/wsdl/default.asp

Office Server Web Services got duplicated in IIS

Hi,
I have a very strange issue. We are using MOSS 2007 on a Windows Server 2003 64-bit environment for our company Intranet. For some unknown reason in our server hosting the Central Admin, the Office Server Web Services site in IIS got duplicated. The old
one was stopped and the new one is currently running. I'm not sure what could have triggered this to happen. What would be the impact if I delete the newly created one and start the old one? This is only happening in one of our servers in the server farm.
All other servers are fine.

Hi Terri,
Did you get any response to this query? I am also facing exactly the same issue. In case you knew the root cause, please share the same .

How to expose a SOAP web service from HCP

Hello All,
Currently I am trying to create a SOAP web service within a HCP Java application to allow backend systems to consume data stored in HCP.
This is the planned scenario:
1. Create data in HCP - therefor I am using JPA and a oData Model.
2. Backend uses web service to consume data from HCP - with this point I do have some problems.. I do want to create a SOAP web service in order to achieve this.
Is there an easy way to create a SOAP web service in HCP? There are many tutorials in the internet of how to create a SOAP web service in 20 sec´s, but non of these helped me. I do was able to consume a SOAP web service in HCP coming from the ByD, but the other way around seems pretty complicated...
Can I make use of the Eclipse functions to create a web service? (New --> Other... --> Web Services --> Web Service and than choose the Button up Java bean Web Service type)
Have any of you some coding snippets that would probably help me out?
I have unsuccessfully tried to use the @WebService, @SOAPBinding, @WebMethod notation in my java classes...
Thank you,
Swen

Hello Nedelcho,
Yes. All the required jar files are in the lib directory.
Currently I am able to create a web service locally.
But when I deploy that to the cloud server my JPA service is not working any more.
Receiving the following error message:
<?xml version='1.0' encoding='UTF-8'?><error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><code/><message xml:lang="en">javax.naming.NamingException: Error while attempting to resolve reference [Root exception is javax.naming.NamingException: Cannot create resource object instance due to exception in the object factory [Root exception is javax.naming.NamingException: Data source 'jdbc/DefaultDB' not available.]]</message></error>
The web.xml contains the following:
Any advice?

Discovery System: Problems with exposing RFC as web service

We have a version 2 discovery system and have successfully implemented the three exercises from the TechEd workshop (Sales Order Distribution, Creating a PO Store Record WS, Adding a New Step to the Procurement Scenario with SAP CAF GP). It seems to work fine except for two issues with the RFC/WS:
1) The RFC, and therefore the WS, always returns an empty string instead of the 'X' that the documentation shows in Step 4.h. We checked the RFC itself and it looks like it has an error with the price field; it always appends a blank to the end of the price string and then errors.
2) The created web service does not show up on the Web Services Navigator page. Since the instructions tell you to save the URL to the WSDL, we can find the web service and test it, but you cannot find it on the Navigator page.
Neither of these problems are huge, but they make me worry that something is not quite right in the Discovery System and we may end up with larger problems later. Any ideas what could cause these two problems, and how to fix them?
Thanks, Eric

Hi Eric,
First of all let me assure you that your system is perfectly fine and both topics that you have raised are the way the system is suppose to respond.
1. The reason that the service is returning a null is because you are entering the same input parameters more than once. Since some of the parameters are used as primary key's in the database, you will need to change them in order to successfully store the data.
2. The reason that you don't see the service in the Navigator page is because this service resides in the ERP and not in WebAS. Only services deployed on the WebAS will appear in the Web Service Navigator page.

Hi,
have you checked OSS note 809901? It looks like your problem. If not have a look on service.sap.com there are some other OSS notes related to "Deserialization Failed".

Best practices for exposing BPEL as web service on the Internet

Hello can anyone tell me if there are any best practices to exposing a BPEL process to the Internet using SOA Suite 11g. We want to create a separate domain that will contain the few processes that will be need to be accessed by external services. We obviously have to do this in a secure manner, so any help in this area on how to do so would be greatly appreciated.
Thanks in advance.

How to expose sort attributes in a web service created on a AM 11g TP4

I'm using Jdeveloper 11g TP4 to create a web service on the application module.
When I run the web service, it is working fine. Can someone tell me how to expose the sort attributes for the user to choose?
How do I expose the sort Order for the user to select?
These are the steps I followed:
1) Created a new application.
2) Created a view object in the Model project.
Created one bind variable.
Created new view Criteria and used the bind variable.
3) Created a new jspx page.
From the Data control dragged and dropped the Named Criteria on to the page and used "ADF Query Panel with Table..."
4) Ran the Jspx page. It works fine.
Double Click Application Module.
Click on tab Service Interface.
Hit New, this will open the Wizard to Create a new Service Interface.
Followed instructions and selected all the applicable methods to expose as web service.
At the end of the process, wsdl, xsd, java files are created.
I'm able to run this web service.
The field to query the data is exposed in the Web Service.
Is there a way to expose the sorting attributes to be selected by the user? i.e. I want to expose the fields to the user.
Thanks,
Jagadish.

Why bother with TP 4? JDev 11g is already production.
