Remove "sslVersion=3L," from Sample R Code Invoking a Web Service, as a Result of Azure Disabling SSLV3 Support

Hello everyone,
As part of January security updates, Azure has disabled SSLV3.0 support by default for Azure Cloud Services customers, effective 01/19/2015. For details, please check
Security Bulletin.
As a result, the sample code to invoke a web service will not work if SSL version 3.0 is specified. For example, R sample code has
# Accept SSL certificates issued by public Certificate Authorities
options(RCurlOptions = list(sslVersion=3L, cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))
You will hit errors as below
* Hostname was NOT found in DNS cache
* Trying 191.238.225.148...
* Connected to ussouthcentral.services.azureml.net (191.238.225.148) port 443 (#0)
* successfully set certificate verify locations:
* CAfile: C:/Program Files/R/R-3.1.2/library/RCurl/CurlSSL/cacert.pem
CApath: none
* Unknown SSL protocol error in connection to ussouthcentral.services.azureml.net:443
* Closing connection 0
Error in function (type, msg, asError = TRUE) :
Unknown SSL protocol error in connection to ussouthcentral.services.azureml.net:443
The mitigation is
Upgrade R client's RCurl package to the latest version (in RStudio, this can be done using Tools -> Check for package updates)
In the sample code, remove sslVersion=3L.
AzureML team is aware of this issue and an update to the sample code is scheduled soon.
Thanks,
Jing

Or, if you want to be explicit, set sslVersion = 1, that also works,
Thanks,
Jing

Invoking a web service from a java code

Hello
I created a simple Web service using JDevlper. It contains two methods
1) getInf int () {
return inf;}
2) void setInf (int a) {
inf = a;}
I have deployed it on Oracle Application server. By inserting the address in a browser, I tried both methods and it works correctly.
Here I am looking how to invoke this web service using a java client and use the method setInf (5 ) / * for example * /.
I search but I have not found an answer that works :(. I hope you could help me to solve this problem.
Thank you in advance

Because you weren't told what to get, perhaps you already have it eh?
What you want to read up about is JAX-WS, which is the webservice API bundled by default with your JDK (Java 6 and up). You'll find the wsimport tool in the bin directory of your JDK. I recommend you explore that directory and read up about all the executables you can find there, to be more prepared in the future. Know the tools you work with and all that. Most tools have a manual on this website:
http://www.oracle.com/technetwork/java/javase/tech/index.html
(under tools and utilities). Not wsimport, that is part of the jax-ws documentation. Better you look for jax-ws tutorials using Google, it will be quicker.

Invoking a web service from jcd

hi all,
Is there any built-in class in CAPS5.1 for invoking a web servervice from jcd directly. Or is there any some other automation/mechanism to achieve the same, plz provide me any sample code avilable for the same.its very urgent for me.
Thanks

Hello rss,
If you want to invoke a web service from a JCD you will have to build the SOAP message using JAX-RPC or AXIS and then programmatically creat an HTTP connection.
Or you can leverage the HTTP(S) eWay and then you only have to build the SOAP message.
Or use eInsight. You can import a WSDL into eInsight and eInsight will offer you a business process Activity to invoke the web service operations defined in the WSDL.

Invoking Asynchronous Web Service from BPEL Process

Hi,
I have been working on the BPEL Process Manager for some time and now facing problem in invoking asynchronous web service from a BPEL Process. I have implemented a web service in Java using Axis but wasn't able to invoke it.
I have gone through all the meterial available on this site but couldn't get any great help.
Can some one help me in resolving this issue. A pointer to any example or sample material/tutorial will be appreciated.
thanks
Farooq

I do the same thing.
Take wsdl from axis and save it somewhere.
Then you can create a standard project in Oracle BPEL PM. Create partnerlink, give a name and click on first icon to take your wsdl. It will add some needed code, you answer always yes. Then you can create receive, assign, invoke, assign and callback or similar and deploy it.
Try it through BPEL Console...

Problem invoking a web service from soa11g BPEL.

Hi ,
I am trying to invoke a web service from soa bpel 11g composite.
We have the wsdl, wsdl URL of the web service along with the user name , password credentials.
Initially w/o any WS policy attached and testing the composite, it fails with the below message
*<fault>*
*<bpelFault>*
*<faultType>0</faultType>*
*<remoteFault>*
*<part name="summary">*
*<summary>An Authentication object was not found in the SecurityContext</summary>*
*</part>*
*<part name="detail">*
*<detail>javax.xml.ws.soap.SOAPFaultException: An Authentication object was not found in the SecurityContext</detail>*

*</part>*
*</remoteFault>*
*</bpelFault>*
*</fault>*
*<faultType>*
*<message>0</message>*
*</faultType>*
*</messages>*
So I have gone back to the composite and added the WS policy (oracle/wss_username_token_client_policy) by Right clicking on web service -> Configure WS Policy -> Security -> oracle/wss_username_token_client_policy -> OK.
After this I have added the following binding properties 'oracle.webservices.auth.username' , 'oracle.webservices.auth.password' with the respective values and deployed it again.
Even then I face the same issue. I have looked into the EM console and found the HTTP username and password properties were blank for this Web service even though the WS policy was attached.
Later I have tried editing the username pwd from the EM console, only to find out that the composite was now failing in the previous step (an ordinary db adapter with a select statement) even before it reaches the web service invocation.
If I redeploy the composite, the http username and pwd properties in the EM console are erased and when i test it, it errors out at the web service invocation with the same issue again.
Any pointers on how to solve this issue ??
How can I figure out what is the security policy the web service is using ??
Regards,
Shiva Kiran

Hi,
Can anyone help me with this ??
I guess I am not able to send the authorization credentials via the request to the web service invocation.
Plz help ! This is a bit urgent..

10g: Invoking a web service asynchronously from BPEL

Hello,
I am trying to figure out a good, generic method for making a previously synchronous web service asynchronous and changing the way in which it is invoked from BPEL. I am using SOA Suite 10g (10.1.3.5)
As I understand, one possible method to achieve this is to use IDeliveryService.post() to deliver the web service's response to the BPEL process. For this route, the standard practice of correlation seems to be to supply a correlation Id when invoking the web service and returning the same correlation id as a part of the web service's response message. However, I want to avoid this since it would mean that all response messages from the web service (10+) would have to be modified to include a correlationId, which is problematic in the special case of this web service. Including a correlationId in the request message is possible, however.
I have tried the approach of using the conversation Id directly instead of the correlation Id, by reading the value of ora:getConversationId(), passing this to the web service and setting the property CONVERSATION_ID of the response NormalizedMessage to the same value when returning. However, I cannot seem to get this approach right. Is this possible at all?
An alternative might be to use WS-Addressing, but I do not know if I can make the web service support this - it is written using the EJB WebService-Annotations feature and runs on OC4J as well.
Do you have any suggestions on how this problem could be resolved?

I have found the following tutorial that implements something similiar to what I am trying to do: http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/odi/10g/10135/odiscenario_bpelcallback/odiscenario_bpelcallback.htm#t3
Because of this, I am now confident that the conversation IDs can be used to achieve correlation. I have implemented the pattern by performing
an invoke activity on the web service, passing the result of ora:getConversationId() as part of the message. The conversation Id returned is of UUID-Form.
After the invoke activity, I have added a pick activity to receive the response message supplied by the web service through IDeliveryService.post(...). I can see that the message is received correctly by loooking at the contents of DLV_MESSAGE. However, the pick activity times out every time (after 10m). Looking at DLV_SUBSCRIPTION reveals that the conversation_id for the pick/receive activity is set to a value of the form bpel://localhost/default/MyBpelProcessName~1.0/7610001-BpInv0-BpSeq2.7-2. As far as I know, this should instead be set to the UUID that ora:getConversationId() returned before performing the invoke activity. What is going wrong here?
Thanks for your help!

Invoking one web service from another web service

Hi there,
I want to invoke a web service lets say X. But befor sending parameters to this web service, what i want to do is first pass the parameters to a web service called Y and Y will decide wether to call X or not. In other words i want to invoke a web service from another web service.
Its kind of urget so do the needful asap.
Thanks

Calling another webservice from within a webservice does not require anything special. The service (say svc1) that calls another service (svc2) will be a web svc client. So you will have to do the same steps for svc1 as you would do for any other web service client

Invoking a Web Service from a mobile application

Hi all,
I have installed Sun Wireless Toolkit 2.5.2 for CDLC and MTJ.
I want to invoke a web service from an MTJ Application and I have not a clue of how to start.
First let me say I am working with RSA (which is over Eclipse)
My first attempt was creating the web service client and then try to convert it into a mobile application (through the use of MTJ --> Convert to Midlet Project)
I found 4 errors when doing so:
First was solved changing the jre to 1.6.
I am still dealing with the following three:
* Error preverifying class mipaquete.MiServicioService
java/lang/NoClassDefFoundError: javax/xml/ws/Service
* Error preverifying class mipaquete.ObjectFactory
VERIFIER ERROR mipaquete/ObjectFactory.createMiOperacion(Lmipaquete/MiOperacion;)Ljavax/xml/bind/JAXBElement;:
Illegal type in constant pool
* Type mipaquete.MiServicioPortProxy$Descriptor Error preverifying class mipaquete.MiServicioPortProxy$Descriptor
VERIFIER ERROR mipaquete/MiServicioPortProxy$Descriptor.getDispatch()Ljavax/xml/ws/Dispatch;:
Illegal type in constant pool
I only started to solve the first one. I assumed that I have to add the right .jar to manifest file (please let me know if I am wrong). I tried to do by adding the textual classpath rt.jar, however I am not able to give it the right path:
C:\Archivos de programa\IBM\SDP\runtimes\base_v7_stub\java\jre\lib\rt.jar (even though I split the too long sentence into two and I include an space at the beginning of the second, I still get an error when saving)
I would appreciate any help
A) to solve the existing problems
or
B) To create a web service client in an EclipseME application through any other method.
Thank-you very much in advance,
Guadalupe
PS Any clue is welcomed!!

How to invoke a Web Service from PL/SQL with Complex Type as input.

Hello,
I am trying to invoke a web service from PL/SQL using the UTL_DBWS package.
The web service expects a complex type as input (defined below):
<xs:complexType name="MsgType">
<xs:sequence>
<xs:element name="sender" type="xs:string"/>
<xs:element name="messageId" type="xs:string"/>
<xs:element name="messageType" type="xs:string"/>

How to remove a photo from a LRPublishedCollection without affecting the Publish Service?

Hello guys!
I would like to know if there is a way to remove a photo from a LRPublishedCollection without affecting the Publish Service. Basically I would like it to be removed from the collection but I don't want to be added to "Deleted Photos to Remove".
Thanks a lot!
Jordy.

I don't know how to keep it from being put on the "Deleted Photos to Remove" list at least briefly, but if you do this, it'll amount to the same thing:
* save status for all photos in collection
* set status of all photos to "do not publish"
* remove photo from collection.
* publish the collection, and make sure you call the deleted callback, but don't do anything else.
* restore previous photo statuses.
Only works in Lr4+.

Invoking a web service

Hello All,
I am trying to invoke a web service hosted on webMethods (our R/3 being an older version, can't expose function modules as web services). I am able to generate Java proxies from the wsdl provided by webMethods. But, I found by studying the generated Java proxies/stubs that its required to send both input (import) and output (export) parameters to invoke the function module.
To give you an example, lets say, my function module takes 3 input parameters and returns 120 output parameters. So, to invoke this function, I thought I just need 3 parameters to be supplied to make a call like invokeXYZ(param1, param2, param3). But, when I looked at the generated code, I saw that I need to supply a total of 3 + 120 parameters to invoke the web service. 120 of them are empty objects of type output parameter.
I think either SAP isn't generating the proxy classes correctly (You don't want to supply 120 arguments to make a call) or I am doing something wrong.
Any suggestions/comments appreciated.
Thanks,
Kiran

Invoking a web service not created using oracle web service lib

Hi All,
I have a need to invoke my web service from oracle sql command. My web service not created using oracle web service library, but it is created using axis c++ libraries. Is it possible to do so,
Thanks in advance,
Regards,
Monica

In order to call out from the database process, is SQL (or PL/SQL) you need to generate some client code, that understand the details about the specific of the service you want to invoke and can produce the correct SOAP request. Once this proxy is uploaded in the Database, you can use it.
There is a set of Database Web services samples that should help you get started. You can also take a look at the developer's guide - see Developing a Web Service Client in the Database.
Hope it answers your question.
