Automatic composition of web services

Hi,
As we all know human involvement in composition of web services makes them time-consuming and error prone. So, do we have the concept of Automatic service composition in Netweaver Composite environment, where we could automatically or semi automatically orchestrate web services. I have searched all wikis but couldn't find more about this work.
Best Regards,
Falak

Hi !
As far as I know, the upcoming version of NetWeaver Composition Environtment 7.2, will include an enhanced Composite Designer, that will include a new central entry point for modeling and assembling composite applications and also a new Service Composer, allowing service composition and simplification, by providing a single service based on multiple backed services.
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/f04a0a13-0ca1-2c10-0dbc-b5e131982f62
I also suggest to use the BPM only with automatic activities, as a BPEL engine.

Are all RFCs and BAPIs automatically exposed as web services?

Hello,
Our product helps business users exchange data with SAP. We use standard RFCs and BAPIs to communicate with SAP. This is a .NET application although my question is not specific to .NET.
It seems SAP obsolete their .NET connector in near future. The emphasis is on web services. This is a great move. We can simply drop using the .NET connector and start using the web services. However, I have a few doubts:
1. RFCs and BAPIs are automatically exposed for remoting. When the customer installs our application, it just works out of the box. Customers do not have to make any configuration changes to SAP to expose RFCs and BAPIs.
In the new world, are all RFCs and BAPIs automatically exposed as web services or one has to go through each RFC/BAPI and expose it explicitly?
2. Is there a comprehensive WSDL schema available anywhere for all the RFCs/BAPIs?
3. Are there any other web services (besides RFCs/BAPIs) that SAP Netweaver exposes? Where can I get more information?
Thank you in advance for your help.
Regards,
Pradeep

Darryl,
Thank you for your help or at least trying to help me. However, you left me with more questions than answers:-(.
1. "Old" does not mean "bad." Each RFC/BAPI serves a specific function. If some RFC is being obsoleted, there must be a replacement documented somewhere. Is there one?
2. I can look into SE80 (and other transactions) to see what is exposed. However, what I need to understand is what is SAP's stance on exposing standard web services.
Can others please share your thoughts?
Regards,
Pradeep

OBPM10g - Dynamic selection of web service WSDL or endpoint

I'm consuming a web service in Oracle BPM10g. The user gave me 2 WSDL files: one for DEV and one for UAT environment, they have different file names but the only difference is their respective endpoint. Introspecting the DEV WSDL generated the catalog structure: Services.myWebServiceDev, whereas introspecting the UAT WSDL generated the catalog structure: Services.myWebServiceUat
Right now I am testing in DEV. I have declared instance variables whose type is something like: Services.myWebServiceDev.type1
What will happen when going to UAT? Will I have to declare all my instance variables again but now with the structure generated during UAT WSDL introspection (e.g. Services.myWebServiceUat.type1) and dynamically select what type of variables to use (dev or uat) depending on the server the project is being deployed to?
Or
¿Is there a way to select/change dynamically the endpoint associated to one introspected WSDL so I can only change this endpoint value (in an automatic activity before web service invocation) depending on the deployment server so I don't have to re-declare all my variables again?
Thanks.

Oracle service bus and composing two web services

All,
Do let me know your thoughts on this.
Currently we have two web services
Web Service 1 - Verify Eligibility
Web Service 2 - Approve Proposal
Web Service 1 has one operation and accepts a well defined set of input parameters similarly web service 2 also exposes a single operation and accepts a set of input parameters.
These are deployed and running in our environment.
Now we have a requirement to stitch together these two web services and expose them as one single composite web service on the Oracle Service Bus 11g.
I want to create a proxy service on the OSB as unified web service (having its own WSDL) by composing the operations and input plus output parameters of the aforementioned two web services.
This way we can publish the WSDL to the front-end apps and they will trigger it with the required parameters and the proxy service will orchestrate the call to WS1 and WS2 and send the final output back to the calling client.
I was able to create an outbound call from the Proxy service to the underlying business services but I am not able to expose the Proxy service as web service with a WSDL i.e. create the proxy service by choosing operations of Web service 1 and web service 2
Please let me know your thoughts on this.
Regards,
Sushant

Thanks Atheek
The proxy service I tried to create orchestrate 2 web services.
But where we are struggling is How can i make this proxy service (composite) as a web service along with the WSDL.
The proxy service should be able to accept calls from the client with set of inputs representing both the underlying web services and coordinate calls b/w these two services and return consolidated output back to the calling client.
I am not finding a way to create a proxy service (web service along with the wsdl) which is representative of the underlying web services in a consolidated manner that can accepts inputs on behalf of both the underlying web services, orchestrate calls b/w the 2 web services and return the final output back to the calling client.
example modified to keep it brief
web service1
operation name: Verify Eligibility
Input: Complex type (String name, int Id, String address)
Output: Complex type(String approval status, int Id, String reason)
web service2
operation name: Approve Proposal
input: Complex type(String approval status, int Id, String reason, int Amount, int EmployeeCount)
Output: Complex type (String final status, String recommendation)
Composite Proxy Web Service
name: Composite Eligibility and Approval
Input: Complex type ( String name, int Id, String address, int Amount, int EmployeeCount)
Output: Complex type(String approval status, int Id, String reason,String final status, String recommendation)
The composite proxy should be created in a manner to jam the inputs of both the underlying web services and expose a representative interface on behalf of both the web services. This composite web service interface creation (WSDL) is where we are struggling a bit.
Because the calling clients need a unified WSDL to able to communicate with the composite web service.
Do post your thoughts.
Thanks Again,
Sushant

Integrate legacy web services into BO Universe

I am really stuck. How should we design the universe to integrate data from legacy web services? We need to composite the web service responses along with data warehouse information into unified Crystal Reports.

Where should this question be directed?

Axis - Web service is not getting deployed on https

I am using axis api for creating web service and Tomcat to deploy it. When I deploy the web service first time, it works perfectly, but If I upgrade my web
application, the server-config.wsdd file gets deleted from WEB-INf directory of my web application.
If I try to deploy the web service again, it does not get deployed on https, but on http it gets deployed. I am using following commands to deploy the web
service:
On HTTPS:
java -Djavax.net.ssl.keystore=/root/.keystore -Djavax.net.ssl.keyStorePassword=password org.apache.axis.client.AdminClient -lhttps://localhost/serviceURL
deploy.wsdd
HTTP:
java org.apache.axis.client.AdminClient -lhttp://localhost/serviceURL deploy.wsdd
When I deploy the web service on http, the server-config.wsdd file gets created automatically and the web service gets deployed, but the problem is on https.
Web service does not gets deployed on https and the server-config.wsdd file is not created. Even if I create the server-config.wsdd file manually, the web
service does not get deployed on https. Once I deploy the web service on http, I am able to deploy it on https.
Please help resolving the issue. Thanks.

Hi Reema,
Thanks for your reply.
But here I am not doing replication, I am working on initial upload of vendor master.
For all the standard fields its working fine.
but we have some 'Z' fields so I enhanced the web service with 'Z' fields after that I am not able to save and activate the web service.
Please find above screenshot for error.
Please let me know if I am missing some setting or anything.
Thanks,
Sudhir

Aqualogic ESB Capabilities beyond web services ?

I'm new to Aqualogic 2.0 ESB and I'm exploring integration posibilities and scenarios where it will be useful.
I have some questions regarding limitations and interoperability with other:
- is there an overlap between ALSB 2.0 and WebLogic Integration?
- Is posible to integrate something like a back end system using CICS (ECI) and a client using web services via AquaLogic ? if so, How ?
- How can I use the underlying capabilities of the underlying WebLogic 9.0 server (i.e J2EE Connectors, jdbc pools, etc) from Aqualogic ?
- Can I publish an EJB remote interface running in another app. server as a "service" in Aqualogic 2.0
thanx in advance

I've only gone as far as reading high-level information and seeing some demos, but I think I can answer some of this.
Concerning the difference between ALSB and WLI, it's expected that WLI could be used to build a service that would be an ALSB endpoint. ALSB is a "no coding" interface. You simply define endpoints, transports, and routing rules. WLI is a development platform.
I'm not sure how to interpret the CICS question. Does your client have a web service invocation API? If so, then you could integrate that with ALSB.
To sort of answer the last two questions with a summary, if you can provide a web compatible interface to a component, then you can integrate it with ALSB. That interface could a web service or JMS. Depending on what version of things you're using, you can automatically provide a web service interface to an EJB session bean.

How to trigger web service automatically when xml file generated at static

Hi Experts,
I have developed web service to read content from XML file.
I need to setup like whenever new xml file generated on static location (eg:E:\xml_files) generated web service should trigger automatically.
My requirement:
1) XML FIle content: have 3 tags with nultiple records.
2) Configured Weblogic Apploication server on JDev 11g
3) Developed Java code to read XML content and store it in Oracle Database.
4) created web service and called java class.
above 4 points, which I did already.
I appreciate if any one help me out, when ever new file created on static location, web service should triggered automatically and stored the data in to data oracle DB.
Thanks,
Phani

Hope you are looking for a SOA Suite/OSB solution for this.
If SOA Suite - You can configure a JCA File Read adapter to read off the XML file and then use a mediator/composite to invoke your WS.
If OSB - You can configure a File read transport or a JCA Adapter to read off the XML file and then use a route node/service callout to invoke your WS.

Composite Deployments and web service references

Hi,
I have a composite application that contains external references to the human task web services hosted on our development server; this means that my composite.xml file contains imports to http://mydevserver:8001/ integration/services/TaskQueryService/TaskQueryService?WSDL.
When deploying the composite to mydevserver either through JDeveloper or using the ant script it works fine.
Now I want to make sure that we can deploy the composite to another server, so I have created a configuration plan that replaces all references to http://mydevserver:8001 with http://anotherdevserver:7001
When I run ant-sca-deploy on anotherdevserver I get the following in the ant output and the ant-sca-compile log file (/tmp/out.err):
Load of wsdl "http://mydevserver:8001/.../....wsdl" failed
oracle.fabric.common.FabricException: Error in getting XML input stream: http://mydevserver:8001/.../....wsdl: Connection timed out
This occurs when the script tries to validate the composite.
It appears this is caused by the fact that anotherdevserver cannot see mydevserver and because the script is only validating the composite at this point and the configuration plan is only used at deployment I have no way of overriding this. If it wasn’t for the difference in port number we could use a placeholder server name and point it to the appropriate server in our hosts file.
I have two possible solutions to this issue:
1) Build the composite on my development environment and deploy the jar file with the configuration plan through enterprise manager – This is not ideal because we want to try and automate the process and remove unnecessary dependencies.
2) Install a local Weblogic server and SOA suite and change the references to localhost. However, his requires a lot of resource on our development machines and also means that the development servers have to be configured identically (i.e. same port number) on all development machines (not that this is necessarily a bad thing).
Please can you tell me how you manage your development and deployments and what recommendations you have that might help me?
Thanks,
Dave.

Exception in calling a web service from a composite application service

Hi,
I have created a composite application service with external service as a web service. My web service is deployed on localhost as well as I am running my composite application service in localhost. When i try to test the application service, I get the exception
com.sap.caf.mp.base.exception.InvocationException: Invalid parameters
The exception happens in MPConnector.java 'process' method where I am calling the execute operation on the service.
I have tried testing this through Service Browser as well as creating a callable object on the Application service and testing the callable object.
I am using the NWDS 7.0.06 version
and EP installed on my machine is the Sneak Preview 7.0 sp 7
Will appreciate all help in this regard.
Thanks,

Hi Navneet,
I have verified the input/output parameters. They are simple types. All are Strings. Nothing really complex there.
I have the Service Exceptions added already.
And definitely the permissions are disabled but still this isn't working.
Any more clues might be helpful.
Thanks,
Prachi

How do I configure automatic web service authentication?

Hi there,
I am trying to implement a web service in my form that requires authentication. When I enter the WSDL location in connection properties I am prompted with an 'Authentication Required' dialogue to which I enter User Name and Password which allows me to proceed to the 'Select an operation' section. I select an operation and click Next and am presented with some authentication options (Requires HTTP/HTTPS Authentication , Requires Message-Level Authentication), but no matter what combination of these options I select I am still prompted for User Name and Password when I try to call the web service from the compiled PDF.
The user will not have these credentials. I need the form to include the credentials automatically when the service is called without user input. How do I go about doing this?
Many thanks,
Kieran

You will have to do this programmatically. If you look at the Acrobat Javascript reference it shows you how to use the SOAP object and how you can hard code the credentials for the WS call. Note that by hard coding this you are in essence breaking the security.

Consuming web service in SAP NetWeaver 7.1 Composition Environment

Hi,
I have created webservice in ABAP. can anyone help me out how to consume that in SAP NetWeaver 7.1 Composition Environment.
Thanks in advance.
Dhanu.

Hi Dhanu,
There are several ways of doing this:
1) Publish your web service onto the Services Registry. If you are using CE 7.1 EHP1, you could refer to my blog for this: /people/romit.ghose2/blog/2008/11/21/using-a-simple-ui-to-publish-web-services-to-the-services-registry-in-ce-711
If you are using a previous release, you would have to use the web services available for publishing.
2) Directly enter the WSDL path and create a consumer proxy for it in NWDS.
Hope this helps.
Regards,
Romit
