OIM to provision a web services based application , how ?

Hi All,
I want to provision to a system which is web services based. There is an ESB above that application which accepts requests for creating accounts etc.
I was thinking I could use OIM GTC SPML connector to provision to this system.
I spoke to the team which maintains ESB , and they were asking me whats SPML.so I figured customer's ESB may not support SPML requests.
They have sonic ESB , I dont know much here , as I am new to web services.
Here are my questions
1.What do we expect of Target system if we plan on using OIM GTC SPML connector ?
2.What is the solution for this situation.
3.Would it be a good idea to build a custom connector
Any help is appreciated.
Thanks,
Pandu

Hi,
I have been working recently with the SPML GTC. Here are a few pointers:
i. OIM will invoke the target web-service synchronously i.e. it will wait for a response. So make sure the response is relatively quick.
ii. SPML is just a message format with some security headers included; In your scenario, you can ignore most of this.
iii. The tough part will possibly be the response back to OIM. This has to be in SPML or it will fail validation in OIM, therefore reflecting that the user provisioning failed(even if it did succeed in the target system)
iv. The target system, needs to send back to OIM an ID, psoID, which is what OIM will use to associate the user identity with the target resource. For eg., supposing you send a modifyRequest for an user existing on the target system, OIM will just send a message similar to
<modifyRequest psoID=TargetSystemUserID>
<firstname>NewFirstName</firstname>
</modifyrequest>
so, the point being: be careful what you send back in the response. (In our case we sent back the emailID as the psoID, as it was the key for our application)
v. And Finally, there are some issues we faced with the GTC itself, and have recently filed a bug. This might not be a problem in your case. However, stay warned: the GTC may not be ready for Production yet.
Will be glad to help you further, let me know.

OIM 11g to provision a web services based application , how ?

Hi All,
I'm trying to provision using GTC connector in OIM but the problem is i know how to write a webservice but i'm newbie to OIM 11g so i am not able to integrate my webservice to the OIM GTC connector.
Highly appreciate if any one give me the background or steps to follow how to execute the provisioning using custom web service in OIM 11g.
Thanks

Hi,
-Just trying to help-
Based on OIM 11G requirements:
If your target system is a Web service that can accept and parse SPML-based provisioning requests packaged in SOAP messages, you can use the SPML provisioning format provider and Web Services provisioning transport provider.
You need not create custom provisioning providers.
1-SPML provisioning format provider
TargetOperation value object that is created by the SPML provisioning format provider and used as an input for the Web Services provisioning transport provider:

How to open the link in new firefox window for web desktop based application? Or how to open the mail/website/rss link in new firefox window

I am using the firefox 3.6. My problem is that I am using the web desktop and few web desktop based application directly opens link. If I click on rss link than it opens in same window, so no longer access to web desktop. I want to open any kind of link in new window instead of same window. I have tired to change the value of browser.link.open_newwindow, browser.link.open_newwindow.restriction but doesn't work. Also gone through the https://developer.mozilla.org/en/window.open but not sure where to do this in web desktop based application or firefox where we connect the web desktop?
Is there any way to open the link every time in new firefox window?

Hi Joseph,
the HTMLB link object misses the support for onClientClick through the tag lib, see hbj:link without onClientClick ? and OnClientClick Event for Link HTMLB Component for similiar problems and workarounds.
With this workaround, you can call for example an AbstractPortalComponent, implement doOnNodeReady (with an empty doContent method) and return the PDF, settings the content type on the http before etc.
Hope it helps

How to create Web Service based on PI WSDL message

Hi all,
we have following scenario:
Within PI (version 7.1) we set up a message type and inbound service interface. This service interface should send the PI message to a web service running on a SAP J2EE (version 7.01). As the PI message is sent as WSDL I thought it should be easy to build a web service on the SAP J2EE based on this WSDL from PI.
Unfortunately, I have problems creating the Web Service.
For my current project we integrated the NWDI to the SAP NetWeaver Developer Studio and I'm required to add the Web Service to an existing DC (Development Component) within the NWDI.
What I tried so far is:
- I created a Deployable Proxy Project and within this I created a Client Proxy Definition based on the WSDL from the PI. But I can't add this Proxy to the DCs of the NWDI and I don't know how to implement my own coding here in order execute specific functions.
- I created a new class within the NWDI DC and a public method. Based on this I created a Virtual Interface and a Web Service Definition (WSD). Then I added this to a Web Service Deployment Descriptor. I uploaded this to the SAP J2EE. But I'm not able to access this and I don't know hoe to assign the WSDL here.
I also tried here to create a client proxy based on this WSD as I thought I might assign the WSDL here. But I don't see the WSD in the list of Web Services uploaded to the SAP J2EE...
Can you please advice me how to create a Web Service in such an environment?
regards
René Jurmann

Hi Tahir,
sorry that you needed to wait this long - but this is how I created the web service:
The steps on how to create the web service in NetWeaver Developer studio are nearly the same as described in the blog http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/5838. [original link is broken] [original link is broken] [original link is broken]
Some steps I just skipped and some others I added. Some of the steps I did the way I described it as I needed to connect the web service with the SAP PI.
Prerequisites:
Add Java Perspective and J2EE Development Perspective to the open perspectives.
Within "Window - Preferences - Web Services" check "Soap extensions visible in the virtual interface editor"
The SDM of the corresponding SAP J2EE is configured within "Window - Preferences"
Create a Development Component (DC) with type "J2EE -> EJB Module"
The business logic of the web service will be implemented in an Enterprise Java Bean (EJB). So first the EJB component must be created:
     Choose "File -> New -> Other"
     In opening PopUp choose "Development Component -> Development Component Project"
     Select the Software Component for which you want to add the DC (e.g. "Local Development -> MyComponents")
     Choose now vendor, name and type:
          vendor is an alpha-numeric string of 20 characters starting with a letter - all in lower case
          name is an alpha-numeric string starting with a letter - all in lower case
          vendor and name concatenated must not be longer then 40 characters
          the name can be separated into different part using "/" as separator
          each part of the name must not be longer than 8 characters
          the type is "J2EE - EJB Module"
          you can specify a Caption as general description for the web service
Create new EJB
To create the EJB itself:
     In J2EE DC Explorer of J2EE Development Perspective expand new DC and right-click on folder "ejbModule"
     Choose "New - EJB" with following details:
          EJB Name: <name as for PI service Interface to be created - starting in upper case>
          EJB Project: <pre selected>
          Bean Type: Stateless Session Bean
          Default EJB Package: <corresponds to namespace in PI>
          generate default interfaces: Checked
Regarding the "Default EJB Package" this should be created according the namespace in PI for which all PI objects will be created. This only applies if you have some naming conventions here.
Example:
Namespace in PI is: http://company.net/pi/SOFTWARE_COMP/Application
The corresponding package then is: net.company.pi.software_comp.application
Implement coding for web service
As the web service will be called via PI some transfer variables will be submitted. Most likely, those variables will not be standard type (e.g. String) but a complex type. Those types must be generated as Java classes. Below an example of a complex type I needed:
Data Type
net.company.pi.software_comp.application.types.MessageProcessingInformation
Structure:
     Element name          Element type
     sendingSystemID          String
     interfaceID               String
     businessProcessVariantCode     String
     testIndicator               Boolean
For every element described a public "get", "set" and "has" method must be created in the corresponding Java class:
package net.company.pi.software_comp.application.types;
import java.io.Serializable;
public class MessageProcessingInformation implements Serializable {
     protected String sendingSystemID;
     protected String interfaceID;
     protected String businessProcessVariantCode;
     protected Boolean testIndicator;
     public String getSendingSystemID() {
          return sendingSystemID;
     public void setSendingSystemID(String value) {
          this.sendingSystemID = value;
     public boolean hasSendingSystemID() {
          if(sendingSystemID != null && !sendingSystemID.equals("")){
               return true;
          return false;
All Java classes representing complex types and all classes referenced here (used for sub-types) must implement java.io.Serializable. Java standard types which do not implement this class must not be used as sub-types.
As soon as all data types are declared the real business logic can be implemented:
     In J2EE DC Explorer of J2EE Development Perspective expand DC - "ejb-jar.xml" - <Name> and double click on "ejbCreate"
     In detail view select folder "Business Methods" and click "Add"
     choose name of business method - this should be the same as the PI message type used for the service interface - starting lower case
     return type should be "void"
     add needed parameters fully qualified - including package (as specified in PI and created previously in DC)
     you can mark certain parameters as array if necessary
Remark:
It might be that after saving you get an error. This might be as the package name of one component is copied to the corresponding Java class at the very beginning (before the package declaration within the Java class). Simply delete the string here.
It also might be, that the new business method is only defined in the remote interface class but not in the bean class. Just create an according method in the bean class.
Within the newly created business method within the bean class you can now implement the business logic.
Create a DC with type "J2EE -> Enterprise Application"
In order to create the "real" web service and deploy it to the J2EE an Enterprise Application project has to be created. So create a new DC as for the EJB Module but choose as type "J2EE -> Enterprise Application".
After the DC is created right click on the EJB DC and choose "Add to EAR Project". Choose the new DC.
Create web service for EJB
As soon as you implemented the business logic you can create the "real" web service. Therefore:
     Right click on the EJB name below "ejb-jar.xml"
     Choose "New - Web Service"
     Choose proper "Web Service Name" and "Configuration Name" (probably oriented at the EJB name)
     Copy the URL of the web service - you'll need it later for PI configuration
     on the second next screen use the same name for "Virtual Interface" and "Web Service Definition" (the name should be the name of the "Endpoint")
     the "EAR Project" should be preselected
Unfortunately, the web service can't be used in its current configuration to be accessed by PI. Therefore the Virtual Interface must be changed. To do so, expand folder "Virtual Interfaces" and double click the virtual interface created.
Within the detail view expand in tabs "Mapping" and "Types" the complete folder structure. For any "SOAP Extension" where a namespace can be defined use as namespace the corresponding namespace in PI (e.g. http://corpintra.net/pi/CBFC_GLOBAL_SAP_APPL/BillerDirect) but do not change any "Soap Extension" of a standard Java type. (if you don't have any naming convetions for namespaces in PI you can leave the SOAP Extension here. But then the namespace in PI should be set accordingly.)
Probably it can be necessary on top level "Soap Extensions" in tab "Mapping" to leave "Use Namespaces for Parameters" unchecked. For some of my web services this parameter must be checked for others not - just try.
If you can define a "New Name", "Local Name" or "Item Label" for a Soap Extension then use a name with starting upper case letter. (For Java Naming conventions most of the data type names will start with lower case letters.) Especially the method name must be renamed this way in order to stick to the PI namings.
As a last point to change here check in tab "Mapping" all "Incoming Parameters" which you specified as array. Use for those as "New Name" a different name - do not just simply change from lower case to upper case. This is necessary as on PI we need to create two levels although here only one is specified.
For any own sub-type declared as array the name within the coding should also differ from the corresponding Java Class name the type refers to.
If all this is done you can deploy the web service to the J2EE:
     right click on "Enterprise Application" DC and choose "Development Component - Build..." and build all corresponding components
     right click on "Enterprise Application" DC and choose "Development Component - Deploy"
Test the new web service via <J2EE URL>/wsnavigator/enterwsdl.html
Create PI interface
After the web service is created successfully the PI integration can be started.
Therefore, within the Enterprise Services Builder create a data type according to the web service definition. All components defined on top-level for this data type should be declared as incoming parameter for the web service business method. Therefore it could be necessary to create some sub data types on PI first and add those to the "master" data type.
Ensure that the names of the components correspond to the names defined in the web service (see virtual interface here). Those names must exactly be the same - including lower/upper case. Also take care for the ordering of the components.
In case you need to include arrays following applies:
The upper level is of occurrence "1:1". This has only one sub-entry with occurrence "1:n". The names for upper and sub-level must not equal.
Based on the data type a message type is created. The name of the message type must be exactly the same as the name of the web service business method. (Hint: the name of the web service business method was most likely changed in the virtual interface. Then this name must correspond to the message type name.) Based on the message type an asynchronous inbound interface is to be created (which will be referred in the Integration Directory). The operation name for this interface (left panel) should be the same as the name for the web service business method.
Create PI mappings and routings
How to map (message mapping and operation mapping) from source to the web service message I wont explain here as this depends on the source message. The only important things here are:
     When creating the SOAP communication channel within the Integration Builder the "Target URL" is:
          <J2EE URL>/<Access URL as specified in web service creation>?wsdl&style=document
     The soap action is the name of the web service business method.
     Most likely the web service needs authentication to be executed.

Provisioning using Web service

Hi All,
I have a requirement in which I need to provision users into an application using a web-service.
What I was thinking is to create an Resource Object, Process Definition and a Form for the application. Then call the client of webservice through an adapter attached to the Process definition task.
Can anybody tell me if I am missing any configuration or there is any other way to take this up?
Thanks In Advance
Charan

I was able to call the webservice client using the adapter.
I created one Create User process definition to provision user to the application using the webservice and it was successful.
I also created one conditional process definition Delete User that will call the deprovisioning webservice. But when I revoke the user profile from the application the deprovisioning service was not getting called and I was not able to deprovision the user from application.
Any pointers regarding this will be helpful.
Thanks In Advance

Web services (sample application)

Hello,
we're trying to get the sample applications (including web services) working (using HTML DB 1.6.0.00.87).
First, we encountered "ORA-20001: The webservice was unreachable because either the URL you supplied was invalid, or your environment requires a valid proxy server address for HTTP requests.". After entering our proxy server's address, a new error occurs:
"ORA-31011: XML parsing failed ORA-19202: Error occurred in XML processing LPX-00104: Warning: element "HTML" is not declared in the DTD Error at line 2"
Same thing happens when trying to create a new web service reference based on the tutorial provided by Oracle: http://www.oracle.com/global/de/community/tipps/WebServices/index.html
Any ideas where our mistake lies?
Thanks in advance for your help!

I've run into the same issue. I thought it was because I was using version 1.6, so I upgraded to HTML DB 2.0 today (I am running 10.2 locally). However, I am getting the same error:
ORA-31011: XML parsing failed ORA-19202: Error occurred in XML processing LPX-00104: Warning: element "html" is not declared in the DTD Error at line 2
This happens when I select the IBM UDDI from the list and search for %xMethods% as indicated in the 2-Day Developers Guide.
I get the same error when selecting the Oracle UDDI.
The XMethods UDDI goes out and searches for something, but 30 minute waits have not resulted in any return, although I have gotten "no matches found" in the past. The IBM UDDI has resulted in the same error.
I've check my proxy settings (don't have any) and tried in both IE 6 and Firefox 1.5.
When I pull the search string down to "%", then every UDDI registry search goes off and spins. In the past, I got a huge number of matches from XMethods, but couldn't start paging through for the "xMethod Delayed Stock Quotes" example in the tutorial.
I would appreciate any enlightment anyone can shed on what's happening under the covers.
Many thanks,
Petie

Connecter for provisioning to Oracle Form based Applications

Hi,
I would like to provision users from OIM to Oracle Form based applications.May I know which connecter I have to use?. DB Application table connecter or DB User Management Connecter?.
Also may I know in which table I need to refer to (If i am using Application Table connecter)?.Thanks.

The database application table connector should work fine. Figure out which table contains the user information for the users and you should be fine.
If Oracle Forms actually uses database users just use the database user connector.

HTTP error when trying to access RESTful web service from application

Hi,
We are getting the following error when trying to access a RESTful web service coming from Apex workspace 4.2.1 and Apex listener 2.1:
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-29024: Certificate validation failure
In the Debug report, besides the above I also see:

We get that error whether we use https or http in the URI pointing to the web service. When I test the Web Service in Workspace RESTful service GUI, I get the data back. When I go build an application with a report calling the RESTful Web Service I get that error. Both the Application and the Workspace RESTful services are on the same Apex environment and even the same workspace.
What is odd is that I can actually put the URL of the web service into a browser and I get the data: (using the demo hr data in sample RESTful services.)

Any ideas on what would be causing the Error above in our application?
Thanks,
Pat
Edited by: patfmnd on Mar 11, 2013 3:25 PM
In reviewing the above error, I think we are realizing that we have to have the Weblogic layer SSL cert (actually the CERT from our BigIP load balancer which also does our SSL termination) imported into the Oracle server wallet where Apex is installed. Am I correct?
PM

We resolved our problem. The Apex Administrative Guide made us realize that we had to set up Wallet path in the Instance. This required working with DBAs to follow the Advanced networking guide to get the wallet set up on our server. We then added that path to the Instance configuration. (Manager Instance --> Instance settings). We ran into another other issue related to our implementation of CAS but were able to resolve that, and 'voila' were able to get the sample RESTful service consumed by our application!!
Now to the task of figuring out how to get Basic Auth working between client application and RESTful web service. If anyone has that working, let us know!!
It would be helpful if in the documentation of the Apex 2.x listener or Apex install/configuration there was clear reference to the above steps required for HTTPS access to RESTful web services.

Problem in Web Service from Application Service

Hi All,
In Netweaver CE I have created a CAF project and within the project I have used one WebService as external service. Now to access the web service I have created an application over on the extrenal service( Just right clicking on webservice -> default mapping). Then the application service is exposed as web service. At that time I have also created Web Service Destination and mapped (External service mapping) the external service with that specific destination. Now my task is to test the web service from netweaver WebService Nevigator. At the testing phase I am providing one input value and executing the WS but it is not accepting any input value. I have also done the debugging in backend system but in backend the input value is acception as zero. That means the web service is not accepting anu input value.
Did anybody face the same problem for NetWeaver CE or any sugestion?
Thanks
Chandan

Hi Chandan,
You need to create a custom wrapper operation in the application service where the operation by default mapping gets created. From this custom operation you need to call the operation created by the default mapping. In the web service you need to expose the custom operation only.
Thanks,
Dipankar

XI web service WDJ Application

Hello everyone,
I am trying out the tutorial -
How To Develop a Simple Web Service Application Using SAP
NetWeaver Developer Studio & SAP XI 3.0
I have done all the steps as mentioned to consume the XI Web service using WDJ. However I am unable to find a way of providing the XI server authentication (username/ pw) to execute the Web service.
If I try to execute the WebService using tools like Altova XML spy it asks for XI server authentication. I know I must try to provide the same using my WDJ application. Can you please tell me the way of doing this.
Thanks and Regards,
Ashwin Bhat

I found a possible solution:
Following is mentioned in Riyaz Sayyads Blog.
/people/riyaz.sayyad/blog/2006/05/08/consuming-xi-web-services-using-web-dynpro-150-part-ii
XI does not accept unauthenticated requests. Hence, you have to pass the logon credentials along with the request. For this add following lines of code in the executeRequest_CDWS_MI_CDWS_MI( ) method implementation of the Component Controller:
<!code> wdContext.currentRequest_CDWS_MI_CDWS_MIElement().modelObject()._setUser(username");
<!code> wdContext.currentRequest_CDWS_MI_CDWS_MIElement().modelObject()._setPassword(password");
I will try this out tomorrow at work (at home now). Will keep everyone updated of the results. Thanks.

Web services and Application Integration in Netweaver

I want to create Web services in Netweaver.
Just something simple to begin with. But I need to be able to:
Create the service
Call the service
Register the service [UDDI], and
Expose the service the service using WSDL.
And explain the whole thing in my research paper.
Does the SAP Web AS 6.40 tutorial cover all this??
Maybe the following book would be more useful.
What do you think??
"Web Programming with the SAP Web Application Server"
by Frederic Heinemann, Christian Rau
(Hardcover - August 2003)
I would also like to Integrate 2 applications with different databases, does the SAP Web AS 6.40 tutorial cover this as well??
When will it be possible for a company to buy mySAP (NetWeaver 04)and be able to use Netweaver to create
e.g. a Portal system?
Thanks for your time.

Certainly you can do this in NetWeaver. Here's where to start: http://help.sap.com/saphelp_nw04/helpdata/en/d6/f9bc3d52f39d33e10000000a11405a/content.htm
Try out the SDN downloads of Dev Studio with Web AS and EP6 with WebAS. The portal lets you show off the services yuou build quite easily. Dev studio lets you build them.
