The secure web service call error.

• Integration with the secure web service IS deployed on EBS

  Hello experts,

  I have a REST webservice deployed to an Instance of the EBS. I try to call the web service using a mobile application in the ADF. However, the web service is secure and requires security settings to be sent in the request header.

  Anyone can recall or explain how I can add a custom header to the object of the application for the REST web service? Any help will be appreciated.

  Thank you

  Abhishek

  Hi Abhishek,

  You can do the following:

  String theUsername = "abc";

  String thePassword = "pass";

  String userPassword = theUsername + ': ' + thePassword.

  String encoding = new sun.misc.BASE64Encoder () .encode (userPassword.getBytes ());

  restServiceAdapter.addRequestProperty ("Authorization", "Basic" + coding);

  If you use Webservice DataControl, then automatically the connection information in the login form is injected into the webservice framework.

  Kind regards

• Secure Web Service call

  Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - production
  PL/SQL Release 10.2.0.2.0 - Production
  
  Hello
  Is it possible to contact a secure Web service (ws-security) with pl/sql code?
  I can communicate with a https without problem, but I don't see how I can do for the ws-security header.
  
  Thanks in advance.

  Unfortunately, WS-Security is not supported with the Oracle DBWS utility legend, right now. However, we have a very high improvement gravity request filed for this internallt - so it's probably in one of the upcoming releases soon.

  In the meantime, you may want to consider going back to using UTL_HTTP for it where you can create your own custom SOAP (WS-Security headers in this case) headers-, but keep in mind that UTL_HTTP can be used with types only very basic of Web Services with simple data types, methods, etc. Another and a better solution would be to have a 'bridge' Web Service (via the SSL protocol, perhaps) who speaks to your main Web Service using WS-Security. This WS bridge can then be invoked by your database using the utility DBWS legend.

• [MAF - AMPA] How the custom/override error after the failure of the asynchronous Web service call?

  Hi Experts,

  I am looking for a best practice to make the error handling in the MAF.

  Currently my application is using AMPA and call the REST service.

  However, I would like to know how to handle this kind of error

  1. the device is not connected to the network (can we personalized it?)

  

  2. the device is connected to the network but cannot call service

  

  3 and the other exceptions of the asynchronous call to the AMPA

  In addition, how to mark a method call in the exception handler?

  referring to this http://multikoop.blogspot.com/2014/02/adf-handling-exceptions-from_14.html in ADF tf we mark as exception handler.

  Best regards

  Hendry

  Hendry,

  You have several options. It depends on how you want to handle exceptions:

  -If you just want to hide the mistakes of web service end-user call, you can set the showWebServiceInvocationErrors property in the persistence - mapping.xml to false (you want to generally this set to false, by putting your application in production, the default value is true, because during development, it is more convenient to directly see the errors of appeal WS)

  -If you want to display a custom error message, you can create a subclass of RestJSONPersistenceManager, register for this subclass using the property "remotePersistenceManager" in persistence - mapping.xml and override the handleInvokeRestServiceError method.

  It depends also how you want to process POST/PUT/DELETE requests that fail. Do you want the AMPA runtime register this request as pending for the runtime synchronization action automatically tries to return the claim later? Or you just want to display an error message to the end-user with a text like "try again later?

• Synchronous asynchronous Webservice Web service call error

  Hello. I have the following scenario.

  I created an asynchronous Web Service (WS_1) to SOA that takes a string as input and waits 10 seconds then returns a reminder. I call this Web Service asynchronous to another web service (WS_2) (that I also created in SOA). In the BPEL I use "invoke activity" to call the Web Service asynchronously and below, I use "activity to receive" a reminder of the Service.When Web I test this Web (WS_2) Service in WeblogicEM, I'm not getting any reminder of asynchronous Web Service (WS_1). On the trail of the flow, 'receive activity' is highlighted and said "Receive1 (in progress)".

  -Does anyone know what is happening here?

  -Thank you

  It is not a good practice to call services async to sync processes.

  For your scenario, have the property of the value requiresNew transaction. This property is listed under your synchronization bpel component in composite.xml

• BPM 11 g: call a secure web service

  Hi all

  I need to invoke a web service secured a BPM process. I do the following

  1. to add a reference, I added the customer strategy security "oracle/wss_username_token_client_policy' using option set up political WS on the reference. I also added oracle/log_policy to see SOAP requests being generated.

  2. I added the below properties in the composite.xml slot of the reference binding.ws

  < name = "oracle.webservices.auth.username property" type = "xs: String" "

  much = 'false' override = "may" > SomeUserName < / property >

  < name = "oracle.webservices.auth.password property" type = "xs: String" "

  Override = 'may' many 'false' = > SomePassword < / property >

  But I get an exception during the invocation

  MustUnderstand headers: [{http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd} Security] are not included

  Also the SOAP request sent to the service of reference I think newspapers don't have the password or a usernametoken anywhere. What else must be configured or set to invoke the secure web service.

• ADF Mobile | using secure web services

  
  Hi all

  I'm pretty new to ADF Mobile, I use JDev 11.1.2.4.

  In my Mobile application I want to use the secure web service.

  Here's what I do:

  1. creation of a data control based on the WSDL binding.

  2. get the web service methods in the data control.

  3. during the race, I'm getting that error "oracle.j2ee.ws.client.jaxws.JRFSOAPFaultException: Client from server SOAP fault: Missing < wsse: Security > in the SOAP header.

  When trying to run the WSDL binding in SOAP UI, I need set request username and passwordproperties, then only I will be able to invoke this web service.

  Here, my question is where can I set these properties for the data control to the web service ?

  Please suggest.

  Hi Shay,

  Thank you very much for the reply, I'm able to resolve the problem with the approach mentioned user guide.

  I forgot to set it up for the first time: ADF Mobile allows you to specify a custom provider class in your DataControls.dcx file. This custom class extends oracle.adfinternal.model.adapter.webservice.provider.soap.SOAPProvider . You can use it to specify an implementation of the SoapHeader[] getAdditionalSoapHeaders() method

  Example 9-1 shows how to extend the SOAPProvider and create a custom header has shown in example 9-2

• ODSI web service calls

  Hello
  
  I want to route the ODSI web service calls to different hosts in different environments. In other words, in my development environment, I don't want to call a quick service to "myosb - dev.mycompany.com:7001", but in production, I don't want to call the same service to the "myosb - prod.mycompany.com:8021".
  
  I see that I can configure a different port for the Physics Department in the ODSI administration console. However, it is not very practical, since the original WSDL must contain information port for all environments from the get-go. If the service is reinstalled in the production, I need to update the wsdl file and redeploy my data space for moving. This can be a problem due to the cycle of deployment of my app be out of sync with the service that I give the floor.
  
  My question is: is it possible to configure the addresses to host more dynamically? Is it possible to use a variable to control this information a set of services that are located on the same server?

  You will see a place where you can specify a 'new value' for the wsdl file. So if you make a copy of your wsdl and the change of the

  It seems you could also copy the "service" element (or just the "port" element) in the original wsdl, and substitute in the ODSI console for the appropriate service or port. I've never tried that. I'm not sure if you also need to copy any elements that refer to the service or port.

  Documentation, I understand that I need to create a session, the session is needed to access the secure components since this

  method specific 'ProfileServices.loginUser' was declared as non-secure, restSecurityConfiguration.xml

  In addition, there are two different ways in which I can connect

  1. 1. with the help of RestSession.createSession providing the user name and password.
  2. 2. or by using ProfileServices.loginUser or ProfileFormHandler

  Can someone please clarify

  If you call the REST web service from a Java client, you can create a RestSession object using the createSession method. But in your case you seem to be invoking it with an HTTP request, which, by default, would be considered a GET request by application of the REST of the ATG. So either a GET, he would try to get a property "loginUser" of the component/atg/userprofiling/ProfileServices (based on your URL) that would always fail.

  To call the method ProfileServices loginUser() with your argument, you need to tell the system to the REST of the ATG to process your incoming request not GET, but as a demand that you can do to atg-rest-http-method of the parameter control in your application like this

  http:localhost:8080/rEST/bean/atg/userprofiling/ProfileServices/loginUser? [email protected]& arg2 = password & atg-rest-http-method = POST

  It should work in this way, your restSecurityConfiguration.xml is correct.
