Set dynamic authentication credentials to Partner link - BPEL 11g PS1

Hi,
I am working on BPEL SOA 11g PS1. I need to know how i can dynamically set the Authentication details (Username and password) as well as Timeout while invoking a web service reference.
I have been successful in setting these values using properties of the partner-link which is static.But actually as per my use-case, i need to read these information dynamically from a repository say Database/DVM and set these value while invoking.
Regards
Sesha

Hi Sridhar
Below is the composite.xml snippet which works for me as static mapping. I have added "wss_username_token_client_policy" to the reference interface.
<reference name="getNameService" ui:wsdlLocation="getNameService.wsdl">
<interface.wsdl interface="http://www.amazon.com/css/mmbi/getNameService/#wsdl.interface(getNameServiceSoapPort)"/>
<binding.ws port="http://www.amazon.com/css/mmbi/getNameService/#wsdl.endpoint(getNameService/getNameServiceSoapPort)"
location="getNameService.wsdl" soapVersion="1.1">
*<wsp:PolicyReference URI="oracle/wss_username_token_client_policy"*
orawsp:category="security" orawsp:status="enable"/>
<property name="weblogic.wsee.wsat.transaction.flowOption"
type="xs:string" many="false">WSDLDriven</property>
*<property name="oracle.webservices.auth.username" type="xs:string"*
many="false" override="may">username11</property>
*<property name="oracle.webservices.auth.password" type="xs:string"*
many="false" override="may">password11</property>
*<property name="oracle.webservices.httpReadTimeout" type="xs:string"*
many="false" override="may">30000</property>
<property name="oracle.soa.ws.outbound.omitWSA" type="xs:string"
many="false" override="may">true</property>
</binding.ws>
</reference>
Here you can find property value for oracle.webservices.auth.username,oracle.webservices.auth.password & oracle.webservices.httpReadTimeout are static , What i want to make here is to read these from a bpel variable in runtime.
OR
Is there any means i can do this same basic authentication in BPEL 11g which would support dynamic credentials.
Thanks
Sesha

Creating dynamic endpoint for synchronous partner link. SOA 11g

I am on page 522 of the Developer's Guide and have hit a dead end.
1) There is no such thing as a "Transformation" activity.
2) If I assume they meant "Transform" I am still stuck because you can't use a wsdl as input
3) What is a "copy rule?" I thought that meant Assign, but the Assign dialog looks NOTHING like their screen shot.
I get the CONCEPT 100% but the actual implementation is a complete mystery because this book is fatally flawed.

It's not a link, it is a literal book.
Oracle SOA Suite 11g R1 Developer's Guide
Of more importance to me than sorting out the book is sorting out the issue. I have two partner links I want to be able to set runtime endpoints for. I also want this to be done based on which deployment server the composites are on, but I can cross that bridge later.
One of the partner links is an HTTP Adapter and the other a WS Adapter.
I imported the WS-address schema and created en endpoint reference variable but then I get stuck. How to I use this to change the endpoint of the partner link? The developer's guide says "use a Transformation" which I am guessing means and Oracle Transform (thing that makes xlst style sheets) but Transform only accepts variables as input and output and the guide screenshot is showing wsdls being used.
Also -- looking at "The BPEL Cookbook" (http://www.oracle.com/technetwork/articles/carey-090553.html) I get imediately lost because only partial examples are shown and repeated references are made to this "DynamicPartnerLink Sample" which I can find umpteen million references to but no source for.
OK.. found the source for the referenced wsdl .. and it has nothing I didn't already have.
I am using jDeveloper... I think the cookbook is referring to some other editor. I needs instructions I can follow in jDeveloper because my employer is requiring we use that.

Dynamic Partner link in 11g-urgent pls

Version: 11.1.1.3
All,
I've a requirement to use partner link dynamically. I configured a DBAdapter which connects to a DB called 'DB1'. During run time, my payload has systemID based on the systemID I have to insert the doc to a table in appropriate DB. Note that the no.of DB is unknown. There may be 2 or 3 or more than 3 DB's would exist. How do I achieve it in fusion 11g? Any pointers would be grateful.
thanks
sen

Hi,
If you have differenet DB's ...you can pass the JNDI name to the ad adapter dynamically.Luk at the below post

Partner Link in 11g

In jDeveloper 11g, i use a base process which inturn calls the subprocess.
I am calling a partner link whose procss updates a DB. but in the Composite.xml of the base process, when i add the webservice and specify the wsdl file of the called process in the partner link config window, i get the following message:
Invalid WSDL
A WSDL must have concrete bindings to be used for an external reference.
myfile.wsdl does not have a concrete binding..
i also see that in the called process WSDL file there is no Binding tag at all. since i use the process as an external reference i need to have the Binding Tag automatically generated.
I referred to a tutorial for jDev 11g. in the example, their wsdl file had the Binding Tag automatically generated.
Any suggestions will be helpful..
Edited by: GauravFox on Oct 27, 2009 1:12 AM

I am able to solve the issue with the 'Concrete Binding' in the WSDL.
Apparently, in the 'Design' view of the WSDL file, u need to create a new binding and later drag the new binding to the ' add services' pallet, save the WSDL file.
but now, am having problems while deploying the project.
during deployment, i get the message saying -------

Invoking Partner link bpel gives "exception on JaxRpc.....No route to host"

Hi,
I have developed a bpel process on oracle soa suite 10g; which invokes a webservice;
The webservice method is getting invoked properly by SOAP-UI but the bpel process fails to invoke the same method and gives the following error:
exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: No route to host: connect
Kindly let me know how did you resolved this issue.
In one of the threads(URL given below); I learned that its because I don't have access to the port from the BPEL server .
If that is the issue then how do I resolve that.
Re: Connection issue: No route to host
Regards,
Anurag

also check for firewalls on the server - a good test would be to an attempt to telnet into webservice hostname and portnumber from the SOA Server.

Service Registry's Dynamic Lookup of BPEL Partner Link not working

Hi,
Software : SOA 10.1.3.1
OS : Windows XP, 2000
I have deployed webservice application (GetMaxOfTwo) which will give me max of 2 values. Registered the WS in OWSM with user authentication. Registered newly generated WSDL in OSR (Oracle Service Registry). A simple BPEL Process will call service as PartnerLink, which is configured as "Enabling Dynamic Lookup of BPEL Partner Link Endpoints". As mentioned in the document made entry in bpel.xml as registryServiceKey property containing the serviceKey value to the partnerLinkBinding section.
The entire scenario is working fine and changed the servicekey value to wrong value in bpel.xml and redeployed, as expected it was giving me error message saying invalid servicekey.
Now deployed GetMaxOfTwo in another application server and registered in OWSM. Intentionally stopped the first GetMaxOfTwo application. In the OSR Service changed the binding with new WSDL of OWSM. As BPEL process enabled with dynamic lookup it should execute without any error. But the results in this case was giving error saying the service was down. (Means it is referring to the old GetMaxOfTwo webservice.
What could be the reason?, something is missing in the configuration?

Hi
I am having trouble making the BPEL and Systinet to work together. I have Systinet and BPEL installed separately on 2 different servers. I deployed my web services and registered them in UDDI. I created a new BPEL process and added a partner link to refer to one of the web service I have registered in UDDI. When I create the partner link, it is forcing me to give the wsdl and it also gives an error message " There are no partner link types defined in current wsdl. Do you want create that will by default create partner link type for you?". If I say "NO' then deployment fails. If I say "Yes", then it creates a new wsdl file on the local server etc and gives "<Faulthttp://schemas.xmlsoap.org/soap/envelope/>

Dynamically change a partner link config property via the BPEL Consle

Is it possible to dynamically change a configuration property
for a partnerlink in the BPEL Console?
From Help in Jdev:
- Double click Partner Link
- Property tab
-- Help
--- "Property Tab"
Partner link properties are simple name-value pair properties that
are defined and can be accessed at runtime by the BPEL process.
The value of a property can be changed from Oracle BPEL Console
at runtime without having to redeploy the BPEL process.
Steps to reproduce:
1. Set the configuration property retryMaxCount on a partnerlink
2. Enter the BPEL Console, click on the process and then the descriptor tab.
3. Not seeing a utility to change the value in the BPEL Console.

Hi Dave,
the console only allows changes to activation agent properties.
There are two kinds of partnerlinks. Those associated with a receive (inbound, activation), and those associated with an invoke (outbound, webservices invoke). Only the former polling process properties can be configured from the console.
Outbound there are only a handfull of properties and the lifecycle management is not the same.
Thanks
Steve

Why we use Dynamic Partner Link in BPEL process

hi,
What is the purpose of using Dynamic Partner link in BPEL process ?

Hi Shankari,
apart of using the the config plan you can change the endpoint uri in runtime if you define the property "endpointURI" in your composite
<binding.ws port="http://xmlns.oracle.com/bpel/workflow/taskService#wsdl.endpoint(TaskService/TaskServicePortSAML)"
location="http://localhost:7001/integration/services/TaskService/TaskServicePortSAML?ORAWSDL"
soapVersion="1.1">
<property name="weblogic.wsee.wsat.transaction.flowOption"
type="xs:string" many="false">WSDLDriven</property>
<property name="endpointURI"
type="xs:string" >http://localhost:7001/integration/services/TaskService/TaskServicePort</property>
</binding.ws>
then right click your composite in the enterprise manager and go to "Service/Reference Properties". There you can change the endpointURI property.
You can also change the endpointURI inside your BPEL process. Go to the invoke inside the bpel process and go to the "properties" tab. There search for the property "endpointURI" and set a value.
hope this helps
cheers Nicolas

Dynamic Partner links in BPEL (or ESB

Can we dynamically define Partner links at runtime and at runtime decide to call these services? If yes, can we also dynamically map the schemas?
BPEL cook book provides an example to for creating Dynamic Partner but this requires redeploying the WSDL?
This is not acceptable because redeploying the WSDLwill effect other processes running.

Just for your information it is recommended when dealing with Batch type processing that the you do not use BPEL variables larger than 5MB.
Therefore is this is the case it might be worth considering a mechanism (as described above) to de batch the process to provide a flow of data rather than a big hit of data.
Hope that Helps
Dave

Invoking secured service using BPEL partner link - basic authentication

HI,
We are invoking a secured service using partner link. The below property is defined in bpel.xml (basicHeaders property is created on partnerlink)
<property name="basicHeaders">credentials</property>
My concern is how the basicusername and basicpassword is sent to the secured webservice?
is it sent in the calling uri ?
I don't think it will be sent under soap header..
Please anyone confirm.
Thanks

How to pass login credentials dynamically to secured partnerlink in a BPEL

Hi,
I am trying to invoke a secured web service from a BPEL.And requirement is to dynamically pass the username and password . I have done the following steps to pass the login credentials to the partner link.
Infact I have followed one of the oracle forums.BUT ITS NOT WORKING.
====================================================================================================
1. Imported the xml schema "oasis-200401-wss-wssecurity-secext-1.0.xsd"
2. Created a variable "SecurityContext"
<variable name="SecurityContext" element="ns2:Security"/>
3.Created a copy rule.
<copy>
<from>
<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:Username>myusername</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">mypassword</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</from>
<to variable="SecurityHeader"/>
</copy>
4. Added the following xml to the invoke operation.
<invoke name="Invoke_1" partnerLink="UnitHealthService"
portType="ns1:UnitHealth" operation="queryUnitHealthInfo"
inputVariable="Invoke_1_queryUnitHealthInfo_InputVariable"
outputVariable="Invoke_1_queryUnitHealthInfo_OutputVariable"
bpelx:inputHeaderVariable="SecurityContext"/>
5. Deployed the BPEL sucessfully.
6. Output message given by BPEL console is
<Faulthttp://schemas.xmlsoap.org/soap/envelope/>
<faultcode>env:Server</faultcode>
<faultstring>com.oracle.bpel.client.delivery.ReceiveTimeOutException: Waiting for response has timed out. The conversation id is a28500bf6f4d1dc9:- 488f4503:1215f79430f:-7d71. Please check the process instance for detail.</faultstring>
</Fault>
7. In the VISUAL flow diagram , message generated by the Invoke activity is as below:
<summary>exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Bad response: 401 Unauthorized</summary>
So FINALLY ITS NOT CONNECTING.
====================================================================================================
When I created the properties and hardcoded the username and password like below, its worked.
<property name="basicHeaders">credentials</property>
<property name="basicUsername">myusername</property>
<property name="basicPassword">mypassword</property>
Can anyone suggest HOW CAN I DYNAMICALLY PASS USERNAME AND PASSWORD to the secured web service via partner link??
Thanks,
Kumar

I have tried it but itwas not working..
I am not able to set exactly the copy rules given in that blog as that blog has wsse:password king of assignments where as when I try to assign , I have the asignment like /ns2:password .
Am I mising something here?
I have imported only oasis-200401-wss-wssecurity-secext-1.0.xsd.
Thanks,
Kumar

No Fault When Dynamic Partner Link Is Down?

Hello,
I have an async process that establishes a dynamic partner link based on runtime data. I understand how to fire off to a dynamic partner link, however, I ran into a problem while testing a scenario where the partner link's endpoint is down.
In situations where the dynamic endpoint is up, my process calls it without any problems. However, when testing what happens if the dynamic endpoint is not available, I expected the process to throw a fault that I can catch. What I find is that an exception is raised in the logs (see below), but the calling process does not throw a fault. The process also continues on as if the call were successful?
Is there something that I can do to ensure that faults are raised in cases where dynamic partner links are down?
<2008-06-07 21:42:13,413> <DEBUG> <default.collaxa.cube.ws> <WSIFInvocationHandler::invoke> invoke failed
org.collaxa.thirdparty.apache.wsif.WSIFException: when invoking locally the endpoint 'http://alcalba2-lap:8889/orabpel/default/CDS_DNS_process/1.0', ; nested exception is:

Exception not handled by the Collaxa Cube system.
An unhandled exception has been thrown in the Collaxa Cube system. The exception reported is: "ORABPEL-02178
Process not found.
The BPEL process "CDS_DNS_process", revision "1.0" has not been loaded. Either the process was not initialized properly or the process has been disabled.
Please consult your administrator regarding this error. The application server logs may provide more information regarding this error.
v10.1.3.3.0
Thanks!

There is a catch all block. I have no fault policies or fault binding set outside of what is defaulted.
Shouldn't my catch all block be enough to pick this up? It's as if nothing is bubbling up to the process and I clearly see an exception in the logs.

Strange problems with Dynamic Partner Linking, how to reset conversation Id

Hi,
We have dyanamic partner linking with synchronous BPEL process. For testing this I have created an xml which is having 3 Dyanmic links for the same partener link. When I execute the first one gets executed but second one onwards it throws bpel fault exception When I am looping through the XML the first linking is working but when it tries to do the second call to the same end point it faults out saying

</part>
<part name="summary">

I tried several ways, bottom line this what I am getting in Do parter link assing in both loops. In my observation it generates some conversation Id which is null in the first iteration but from second one onwards.. it is generating some value which I am unable to reset. I belive if I can reset that converstationId to null probably I won't get this bepelFault.

Dynamic binding of partner links with different payloads

In dynamic binding of partner links, can we have different payloads for different
webservices ?

Hi Marc,
I have one question regarding the use of <xsd:anyType>, Before that let me clear our requirement. We are trying to create a BPEL flow (Consumer) which has the ability to call other webservices (Producers) dynamically. There can be a number of Producer Webservices performing the same task. The end user should be able to add new Producer Webservices and remove already existing ones. We achieved this using EndPointReference (http://www.oracle.com/technology/pub/articles/bpel_cookbook/carey.html) but the problem with this approach is that all the producer webservices have to work on a common schema. We want to support webservices working on different payloads.
My understanding is that when we map the XML document to xsd:anyType in the service's WSDL file, the producer web service need to have an implementation of this type in for of a java class. Is this correct ? Or can we provide the java implementation in our code itself? Can you please point me to some detail documentation on xsd:anyType?
Thanks

A dynamic partner link for very distinct services.

Hello,
Is possible to create a dynamic partner link for very distinct services. for examples 10 services has different operation names, inputs, outputs.
Thank you.

Hello,
You could use an Oracle Services Registry ( UDDI ) to store the WSDL and dynamically select the needed WSDL.
Here is the general idea :
