ESB -- BPEL, Web Services

Hi @ all,
I have a question. My application has a BPEL-Process and 3 orchestrated Web Services.
Is it usefull to use ESB (Enterprise Service Bus) for this application?
Advantages / Disadvantages ??
Thx!

In my opinion the ESB is for routing messages to different targets.
So if you only have one BPEL and all message should be routed to this BPEL, there is no need for using ESB.
BUT if you want to extend your scenario and add other BPELs and more Web Services the it would appropriate to use ESB.
The decision depends strongly on what do you want to do with your application.....
Give more information and propably someone can give you a good hint for your decision.

Running ODI Interface from BPEL WEB SERVICE

Guys,
How to invoke ODI Interface from BPEL Web service?
i.e can we use odistartscenerio?if we can then how to pass conext/agent as parameters?
Cheers

You need JavaEE agent and configure odi run time service. BPEL can then call this service to start an odi scenario.
For details refer to http://docs.oracle.com/cd/E15586_01/integrate.1111/e12643/running_executions.htm#BABDHJJF
and for installation of JavaEE agent http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/odi/odi_11g/setup_jee_agent/setup_jee_agent.htm (as part of extending the domain you get the option to deploy this service)

BPEL web service and siebel integration

We are trying to deploy a web service in bpel - the web service takes xml as an input and calls a pl//sql api in a database to execute a piece of code.
We deployed the wsdl file - in siebel (creats a new business service and 2 integration objects) - and are trying to call the web service (business service) by passing an xml file from siebel (using EAI Siebel Adapter business service).
We are able to call the web service but - unable to pass the input xml -
Any help would be apprieciated.
Regards,
Siddharth

Hi Siddarth,
We are doing similar kind of POC where Siebel team will expose a WSDL at some URL and it need to be called in an ESB or BPEL. We are facing a problem in validating the provided WSDL and not able to generate XSD out of it. Can you tell me how u r able to call the webservice in an ESB(in detail) ??? Siebel and oracle fusion are at different locations.
Quick response would be appriciated.

BAM getting random timeouts calling BPEL web service as alert rule

I have a BAM alert rule set up to call a BPEL process (web service call basically). This is part of our custom error notification and escalation solution.
In production I randomly see timeouts in the BAM event engine logs where the web service call has timed out. On the BPEL side these processes never show as being invoked, nor are they in manual recovery.
This only happens at random times, although usually in "clumps" lasting a few minutes. The rest of the time this has been fairly reliable.
Any help from the BAM experts would be appreciated. I would open an SR on this, but I have found support to literally take days/weeks to get back to me on BAM issues -- and this particular issue does not seem to be reliably reproduceable.
Here is the event engine log message:
2008-01-31 14:46:35,303 [ActionThreadPool (dynamic 11309)] ERROR - EventEngine Action exception: EEInstEv218067 EEInstAct218066 Rule Id: 1 exception: The operation has timed-out. (http://mcsbpel:8888/orabpel/MAEF/svcMaefErrorAlert/1.0)

ESB Invokes Web Service More than once

Hi,
I have an ESB that invokes a Web Service Asynchronously (Using SOAP). In certain scenarios Web Service takes as much as 5 minutes to complete its operations. In such cases i am able to see ESB generating multiple requests to the Web Service. Multiple Requests are not generated in case Web Service completes its operations within a shorter duration (duration is based on business scenarios). I tried invoking the web service directly and i found that web service is invoked only once even when it takes 5 minutes.
Please let me know if any of you have faced similair problems and also any possible ways of resolving this issue.
Thanks,
Rajesh

We found that the default retry property of esb was the root cause of the issue. But still why should the esb retry as the call to webservice is an async one. The ESB should have completed the process.
Why 5 minutes - Webservice performs a lot of validations and also the environment is a development one and not optimized.

M.Rajesh

How to pass username/password to BPEL web service from java proxy?

Hi all,
Environment : SOA Suite 11g
I am using basic http authentication in my SOA services using "oracle/wss_http_token_client_policy" policy. Now i need to invoke these SOA web services from a java proxy.

Error invoking esb from web service proxy

I have created a web service proxy (with jdeveloper 10.1.3.2) to invoke my service on the ESB.
When i try to invoke this service with the proxy, the following error message appears:
HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message transmission failure, response code: 500

at testproxy.proxy.runtime.__soap_TestIn_execute_ppt_Stub.execute(__soap_TestIn_execute_ppt_Stub.java:88)
When i take a look in the esb console, there i can see, that the service was invoked, but it is signed with the error symbol (i'm writing data into a database and the lines to the database adapter a green, but the lines back are red. But it writes nothing into the database. If i klick on the test webservice button at the appserver, everything works fine).
Does anybody know the reason why it don't work?
thanks

In the ESB Control you can view the exception that's being thrown, is the PrivilegActionException the only stack trace you have?
Maybe you can have a look if the data that's returned from the db-adapter is interpreted correctly by the ESB? You're working with a Request/Reply ESB so you need to make sure that as well the input as the ouput that's returned by the Routing Service is properly defined.

Changinf BPEL web service type from "DOCUMENT" to "RPC"

Hi,
When a BPEL process is deployed on SOA Server, by default it creates "DOCUMENT" style web service. I want to change this service as "RPC" styled web service. How can I do that?

sounds more like an issue on the client side ..
as from the error msg;
Caused by: org.idoox.util.RuntimeWrappedException: Systinet server or client can't be started without 'wasp.location' argument
did you already consider systinet or docu on that?
I looked into systinets forum ..

HTTP 404 on ESB Test Web Service

Hi,
I cannot test my ESB service anymore cause, when i click on Test Web Service page of my Enterprise Manager, I receive an HTTP 404 error.
I can't see any error log which colud help my understand the reason for this.
Hoping it can help: this situation started few days ago, while i was trying to create an AQ JMS queue, modifying some configuration files like application.xml, jms.xml and data-sources.xml
I'll appreciate any kind of help

Hi,
I've figured out the cause for previous quoted problem:
in default-web-site.xml configuration file of /j2ee/home I've found a propery ohs-routing set to false.
In forum's thread "Use HTTPS to access webservice on standalone OC4J" that property wasn't set, so I removed it and magically now it works!
My question now is, which event caused such a change in default-web-site.xml file? How can I prevent or even controll it?
Thank you,

BPEL Web Service with OWSM Server Agent NOT AUTHENTICATING

I have deployed OWSM Server Agent to enable WS-Security Username/Password Authentication following the steps in the below URL.
http://www.oracle.com/technology/obe/fusion_middleware/owsm/secure%20soa/securing%20soa%20with%20owsm.htm
Section: Creating and Installing an Oracle WSM Server Agent
The OWSM agent configuration is working fine with individual Web Services.
For BPEL, the authentication is not happening if we call the default endpoint from JAVA proxy or Soap UI e.g
http://host.domainame:7777/orabpel/bpelprocess1/050101 - Authenticates as per the OWSM policy and WORKS FINE
http://host.domainame:7777/orabpel/bpelprocess1 - Executes the process WITHOUT authenticating
Any help would be appreciated.

To invoke the web service, we are just using the JavaScript code that has been generated by BPEL Process Manager. The call looks like:
function invokeSync (url, xmlDoc) {
var req = null; if (window.XMLHttpRequest) {
req = new XMLHttpRequest();
} else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.open("POST", url, false);
req.setRequestHeader("Content-Type", "text/xml");
req.send(xmlDoc);
return req.responseXML;
I have been able to invoke other web services using exactly the same function. They all seem fine.
I am even able to use an AXIS type client to invoke the BPEL web service from Eclipse.
Advice??? This definitely appears to be some sort of bug?
Thanks,
BradW

check out 102.InvokingProcess/ws tutorial .. which uses axis .. or generate the client based on the wsdl that you can retrieve from the bpel console / click on the process/ and then wsdl tab ..

ESB and Stateful web services

Folks,
I’ve got two web services that are called in succession. The first web service performs a search and caches the results on the server, returning only some basic information about how many results were found (in the payload) and a session id (as an attribute in a HTTP header). The second service is called afterwards, passing some page request information (in payload) and the session id (in the HTTP header). The session id is used to find the appropriate search results and return them lazily (based the given page request information).
The web service requests are done through ESB and OWSM. My problem, however, is that according to the ESB developer’s guide (http://download-west.oracle.com/docs/cd/B31017_01/integrate.1013/b28211.pdf , page 5-29, ‘Limitations of ESB Header Support’) ESB is not capable of setting header attributes (at least not SOAP header attributes).
Is it possible to use stateful web services with the ESB? If so, how is the SessionID handled on the ESB and how is it correlated with the clients of the ESB who are getting the results back from this stateful web service?
Thanks in advance,
Joseph

Dave,
We have invoked the two services mentioned above in four different manners using Java code.
1. We are invoking the services through ESB with no success. The HTTP header (set-cookie) never makes it back.
2. We are invoking the services through Web Services Manager (the services are registered directly with OWSM) with no success. The HTTP header (set-cookie) never makes it back.
3. We are invoking the services through Web Services Manager (with ESB providing a wrapper for the services) with no success. The HTTP header never (set-cookie) makes it back.
4. Invoking the services directly (no OWSM, no ESB). This method is successful. HTTP headers are being exchanged without incident.
We are using Ethereal to check out the traffic going back and forth so we can see the SOAP headers getting propagated back and forth as you had mentioned. The problem is that the HTTP headers (as mentioned in my first posting) containing the session information are getting dropped when using ESB or Web Services Manager.
Any suggestions?
Thanks,
Joseph
