Sync Web Service - BPM with 2 sync proxy calls error.

Hi.
Have a sync web service going into a BPM.
In the BPM there ar 2 sync calls towards a system making a credit check.
The answer is responded to the web service.
In our QA system the solution works perfect.
I transported the solution to production and when I test the web service call towards I get the following error.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<SAP:Stack>Timeout condition of pipeline reached</SAP:Stack>

</SAP:Error>
Does anybody have an idea why I get the error.
When I check my config everything looks the same.
Looks like we never send the first sync call to the proxy when I check in SXMB_MONI and the BPM gets terminated.
We have just migrated the solution from XI 3.0 to PI 7.11.

Hi.
How will that help if we do not send the message.
When I check the graphics in SXMB_MONI the error occours befor we send the first message with proxy.
Also extend ASYNC timeout?
We are using sync communication.

Erorr calling long running sync web service

Hello
I have definied simple async process:
assign (from process input to ws invoke input)
sync ws invoke
assign (from ws invoke output to process output)
Sync Web Service is long running (few minutes). In order to avoid timeout I have accordingly set sync-max-wait-time property.
I have observed that after starting process instance I can't see it in BPEL Console (however I know it is working). Furthermore when invoke activity ends (so instance state must be saved in database) I can see following error on system console:

The process domain was unable to insert the current log entries for the instance
"2314" to the audit trail table. The exception reported is: RollbackException:

Hi,
There are 2 ways to work around the error that you are seeing.
Option #1: increase the JTA timeout of the underlying application server.
Option #2: in the bpel.xml of your process, add a "nonBlockingInvoke" property to the partnerLink representing the interaction with the long running service.
Option #2 should also address the fact that the instance is not visible in the bpel console.

Exception obtained when invoking a web service generated with JDeveloper

Hello,
I tried to create a synchronous BPEL process that invokes synchronously a Java Web Service created with the JDeveloper. The web service is wrapped around a regular Java class. The new created BPEL process is successfully compiled and deployed on the server. But when I try to initiate a test instance of the process in the BPEL console, after I fill the input parameter for then process and push the "Post XML Message" button, I obtain the following error:
Your test request generated the following exception/fault:
BPEL Fault: {http://oracle.com/cde/util/Top300DAO.wsdl}org.apache.wsif.soap.fault{org.apache.wsif.soap.fault.object=java.net.ConnectException: Connection refused: connect}
I looked at flow and it throws the exception when it tries to invokes the web service generated with JDeveloper.
Do you have any hints, ideas? Thanks a lot in advance for your help.
I want to also say that the proxy settings for the BPEL server and designer are filled. I think that they are ok because I succeeded to start an instance of another process that calls synchronously an external Web Service.
Regards,
Marinel

My guess is that this is caused by the WSDL of your service having an invalid service address. Can you please take a look at the WSDL of your service make sure that the location of the address is valid? (we have seen a couple of instances in the past where the generated url did not have the right port information).
Update that WSDL, restart the BPEL server or from the BPEL console clear the WSDL cache and re-initiate your flow.
Best,
Edwin

Web Service Security with SAML - Invalid XML signature

Hello together,
we want to build a scenario where we want to use Web Service Security with SAML.
The scenario will be
WS Client (Java Application) -> WS Adapter -> Integration Engine -> WS Adapter-> CRM (Web AS ABAP 7.01 SP 3)
SAP PI release is 7.11 (SP Level 4)
We want to use the SAML Authentification from WS Client to PI and from PI to Web AS ABAP.
The SAML authentifications between the WS Client and PI works when there is no SAML auth between PI and CRM.
But we get following error at calling the CRM system when we want to communicate with SAML:
<E_TEXT>CX_WS_SECURITY_FAULT:Invalid XML signature</E_TEXT>
Has somebody an idea of the possible reason for the error.
Thanks in advance

Adding security to a web service then generating a proxy [SOLVED]

Hi
I generated a web service based on a very simple java program. I have deployed it to a local oc4j install and successfully called it from a proxy generated from jdev. I am using 10.1.3.3.0.
I added security to the web service and regenerated the proxy. I wanted to see the difference in the SOAP messages sent to the web service. However the proxy does not seem to have changed to take account of the new security settings on the web service.
The security options I set were:
On main security dialog: Ticked the port and "Text Password"
On Authentication: Ticked "Expect Username ti Authenticate"
"Password Required"
Password Type = "Plain Text"
"Nonce Required in Token"
"Creation Time Required in Token"
I have 2 questions:
1. How do I get the proxy to send SOAP messages that contain the security headers required to run the web service. Here is the main method from my proxy. I thought adding setUsername and setPassword would be the solution
    public static void main(String[] args) {
        try {
            gpn3.Getphonenum3SoapHttpPortClient myPort = new gpn3.Getphonenum3SoapHttpPortClient();
            System.out.println("calling " + myPort.getEndpoint());
            // Add your own code here
            myPort.setUsername("oc4jadmin");
            myPort.setPassword("welcome");
            myPort.getNum("Lisa");
        } catch (Exception ex) {
            ex.printStackTrace();
2. When the web service receives a user name and password what does it check them against? I assume the oc4jadmin user will be allowed access but how do I set up other users?
many thanks

I have figured this out now
1. I needed to set the same security settings in my proxy as I did for my web service. I had assumed that the proxy would generate the necessary security settings from the web service.
2. For some reason my web service application is using the system level jazn-data xml file
oc4j_extended_101330/j2ee/home/config/system-jazn-data.xml
This does include the oc4jadmin user and I am now able to use that account to call the web service. I also managed to add another user and use that account to call the web service successfully.
Thanks for the help

Web Service consumer using ABAP-PROXY

Hello,
I want to test Web Service consumer using ABAP-PROXY . So I do what is explain in the weblog :
[http://wiki.sdn.sap.com/wiki/display/Snippets/WebServiceconsumerusingABAP-PROXY]
But when I execute the programm, the message : 'No valid source context supplied'.
But, proxy and port are ok and activate.
Can you help me.
Thanks.

Hi Jitesh,
Thanks for the link. I checked but did not find helpful info there.
I have managed to make it work yesterday. Two issues were identified.
1. The namespace in the WSDL file imported into ESR as an external definition. I need to create the same namespace in ESR before importing the WSDL and then import the WSDL into that namespace.
2. The authentication method. The authentication method in the IIS configuration of the .NET web service has to be set to Basic Authentication. Then I set logical port of the consumer proxy in the OSAMANAGER to use Basic Authentication also. So far only the Basic Authentication works in my test scenario.
I am closing this question.

Java Web Services Security with 10.1.2.1

I have developed a Java Web Service with J Developer 10.1.2.1 which was deployed onto Oracle 10.1.2.1 application server. Now I have to implement Security for this Web Service (similar to ws-security etc.,), how I can achieve Security with 10.1.2.1?
J Developer 10.1.3.1 seems to have the feature to implement Web Service Security, but a Java Web Service developed using J Developer 10 .1.3.1 with security enabled cannot be deployed onto Oracle 10.1.2.1 application server.
Please help as how I can implement Java Web Service Security with 10.1.2.1?
Email: [email protected]
Thanks for the help in advance.

You can use Oracle Web Services Manager to virtualize the end point and still implement WS-Security.
Thanks

GetAndPublish web service failed due to an internal error

Hello all,
Been a little while, To start off we have no IP phones connected to Lync. We have a completely separate PBX and VoIP system.
We have one FE server internally used to have internal users use Lync 2013 as a IM interface and Video conference. All users are running Lync 2013 with all the latest updates. Our Lync 2013 FE server is running on Windows 2008 R2 with all the latest updates.
v I noticed in our event log the follow error v
GetAndPublish web service failed due to an internal error. Request Details - Entity: [[email protected]], Device Id: [9A1A1E15-865F-5376-88CD-4384205012F9], Authenticated User: [sip:[email protected]]. Additional Context: [CA_Failure: InternalError] Cause:
This is an unexpected failure Resolution: Re-start the web server. If you see this error continuously, examine the server traces and contact product support.
I have googled and only came across technet forums that state checking certificate related issues.. or based around the IP Phones not authenticating. such as
here, however this guy noted a certain algorithm required by the CA to work properly "RSASSA-PSS algorythm instead of RSAsha1". Now I'm not exactly sure how to check up on this, and I also don't get why everything seems to work fine but I keep
getting these events populating.
I also ran "Test-csclientauth" cmdlet on our FE server and came up with a failure much like on the link I provided above.
Am I to assume these events are being populated because my Lync deployment was set up to use certs techincally not supported by Lync?

Hey Eason,
As I had previously mentioned, I have checked the FE server certs and have mentioned the signing algorithm it used to sign the certs, which was sha1DSA and not sha1RSA, I even checked my CA list of issued certs and have found all certs are signed the same.
Signature algorithm: sha1DSA
Signature Hash Algorithm: sha1
Public Key: RSA (1024 bit)
I could run request and reinstall all day long it will still get the same certs signed with the algo..
Doing some research I attempted to see if I could change the signing cert for a specific cert template that was being used to issue the Lync FE certs... however seems that from according to
this, that I'd have to completely rebuild my CA before I'd be able to request and issue a cert with the proper signing algorithm?!
This
says its possible but not supported, what do I do in this situation? Is my only option to rebuild teh entire CA and cert infrastructure?
I noticed my CSP is set to Microsoft Base DSS Cryptographic Provider, and under the CSP folder there is no "CNGHashAlgorithm" key so I'm using a "Next Gen CSP" apparently? Is this CSP good enough to support Lync...Straight up where is
the Lync documentation on the CA setup requirements??
This google link doesn't tell you how you should setup a CA for Lync, what settings need to set etc..

We are using the Azure server for our web services. Server is generating an error "Unable to connect to the remote server". What is this error means

Hello,
Did you means that you use the Windows Azure Virtual Machine DNS name as the server name in the Reporting Server Web Services URL?
For example:
Report server:http://uebi.cloudapp.net/reportserver
Report manager:http://uebi.cloudapp.net/reports
If you want to connect to Report Manager on the virtual machine from a remote computer, you should create a virtual machine TCP Endpoint and open the port in the virtual machine’s firewall. By default, the report server listens for HTTP requests
on port 80.

Async system - XI BPM Sync - Web service - SOAP response

Dear Experts:
I have the following scenario:
Async Proxy to XI to web service. I use BPM to make this a sync call to the web service. It works fine!
I have a XSLT mapping for the response message from the web service. I use XSLT because the structure of the positive and fault responses are different. Anyway, I could get the positive response post ok back in the XI system.
But the fault response does not get mapped and I get a APPLICATION_ERROR of category UNKNOWN in the SXMB_MONI. I also configured exception handling in the BPM. But it does not catch this error.
Can anyone suggest how to handle the fault response from the web service?
Thank you.

I just had the same problem and solved it like this: I modified the WSDL slightly by removing the prefix from the reference to the element of the response message, as well as the "targetNamespace" in the xsd:schema segment of the WSDL. Like this, SAP is able to parse the response.

ODSI to Invoke an A sync Web service

We have a 2-Tier application based on Oracle 11g db and PowerBuilder 10.
Does the follwoing practice can take place? :
1.call an ODSI Program (Wraped as a service) from Power Builder
2.ODSI will collect the data from the db and send it to a SOAP end point for further processing.
Also , would it be best practice to creat my SOA landscape usign this tool rather then developing
each outbound service using Jdeveloper for example on the application side.
Appriciate your insights.

I'm not sure I understand the post. The subject says "ODSI to (can?) invoke an A sync (async?) web service" (it cannot), but then goes on to ask something different.
1.call an ODSI Program (Wraped as a service) from Power Builder If PowerBuilder supports calling webservices, then yes, you can call ODSI from Powerbuilder.
Also , would it be best practice to creat my SOA landscape usign this tool
2.ODSI will collect the data from the db and send it to a SOAP end point for further processing.The strength of ODSI is that it can part or perhaps even all of the "further processing".
would it be best practice to creat my SOA landscape usign this tool ratherThat would be a good practice.

BPM Studio call web service deployed by R12 Intergration Repository error

Hi, I encountered a problem when calling a web service deployed by R12 Intergration Repository (SOA Gateway) w/ username/password authentication.
It seems that the BPM Studio can not pass the security information to the web service. But using SoapUI it's quite easy to call the service with no error, just set the username and password, and set the password type to PasswordText.
Under the External Resources catalog, I've set fileds in the Security tab with "Plain" Username Token, "sysadmin" Username and "sysadmin" Password, then changed the Authentication Type to "Username Token Profile". Then create a participant named sysadmin, and use this participant to run the process, but it just can't work.
Anybody can help? My colleague also posted a topic here: processRemoteException when invoke webservice from Oracle E-Business Suite but nobody answered. It would be very appreciated if sb. can fix this.

I've encounter something similar to you're problem and it was resolved by manually creating the object using the web service constructor and inputting user credentials. If you manually instantiate your web service wrapper object and set a a security profile token, it may solve your problem. You can also pass in the web service endPoint URL, if you want.
Fuego.WebServices.UsernameTokenProfileSecurityPolicy
I'm not sure how to use UsernameTokenProfileSecurityPolicy, but try something like this:
Fuego.WebServices.UsernameTokenProfileSecurityPolicy policy = UsernameTokenProfileSecurityPolicy();
policy.username ="mark";
policy.password = "password";
tws = YourWebService();
response = tws.callWebServiceMethod();
I realize the security profile isn't tied anywhere to the web service, but try it anyway.
There is also some fields on the webservice, tws.setRequestHeader() that may allow you to set the username and password on the request, but this doesn't make sense to me. It shouldn't be that hard.

Calling Web Service from CRM using proxy

Hi all,
I'm facing a problem trying to call a web service from CRM (WAS 620) via XI 3.0. The response that XI recieves from the web service contains SOAP Envelope, and the mapping fails because of it. I built the proxy manually, because if I load WSDL the proxy generation in CRM generates error that sais that external definition coudn't be used.
Is there any way to remove SOAP envelope from the response while mapping?
Is it possible to call web service from WAS 620?
Thanks!!!!
Anya.

Hi Manish,
SOAP adapter does pass the message to XI (this message contains SOAP envelope although XI expects to get message without it), and during the mapping step i get "Runtime Exception in Message-Mapping transformatio~".
I suppose it's because i created proxy manually. I did so because when i imported WSDL, and tried to generate proxy in CRM, i got an error message that said that proxy couldn't be generated because external definitions are only allowed in XI 3. But my XI version is 3.0! And when I generate the same proxy in my R/3 system that is installed on WAS 640, it works.
What can I do?
Cheers,
Anya.

Calling web services constructed with swaref attachments

Hi All,
BPEL has support for attachments, either in MIME or DIME manner.There are attachment examples under BPEL_HOME/samples/demos/Attachment folder.
Unfortunately, these examples does not cover swaref (Soap with attachment reference) which is widely used for our customers.
What I would like to ask is:
Is there any way to call some external systems introducing web services with swaref elements in their interfaces,from BPEL processes?
When I tried such kind of a web service, I get a remoteFault with summary:
"Caught exception while handling request: missing cid for attachment"

If your question is whether a Web service can be accessed from Java by directly progamming on the HTTP level, then the answer is yes.
