Issue: BPEL invoking Axis web service

Hi
We are calling a Axis web service from BPEL.. The web service has been defined to be a request only 1 way service. The axis service takes around 3-5 minutes to complete the job( data insertion in DB).. But seems like when BPEL invokes the web service; BPEL thread is waiting (thread is not released) and the BPEL process does not move forward until the web service completes the job....
Any pointers on how the deal with the issue will be helpful!!
Thanks

Hi Lovenish,
Goto console-> select domain> Configuration->JTA
Check timeout seconds.
2. i don't know what kind of partner link you are invoking.
check composite.xml, is there any property like retry.interval .
3. ◦SyncMaxWaitTime: The maximum time a request and response operation takes before timing out.
The maximum time a request/response operation will take before it times out. The default value is 45 seconds.

Issues in invoking a web service from a JAVA/BPEL client...

We are trying to invoke a web service from a JAVA/BPEL client using org.apache.soap classes. But everytime we are running into issues of IllegalAccessError or InvalidClassError or IncompatibleClassError based on different jars we are trying to include in our project. Attached is a simple BPEL project which tries to invoke a web service through JAVA embedding (no supporting jars need to be included explicitly). It erros with following trace:
Class org/apache/soap/Envelope violates loader constraints
     Invalid class: org.apache.soap.Envelope
     Loader: soap:10.1.3

Could you please help us out or provide any pointers. Any help would be highly appreciated

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.

TimeOut Issue in invoking Synchronous Web Service in BPEL.

Hi All,
There is one BPEL process which is calling third party web service synchronously but sometimes my requests get failed in 30 sec giving the following error:-
*"oracle.fabric.common.FabricInvocationException: Unable to access the following endpoint(s): https://aaa.bb.cc.dd/abc/def/xyz"*
When I checked this in soa_server1-diagnostic.log, I found that it is giving some Read Time Out error.
Currently following settings are there on the server:-
syncMaxWaitTime = 45 sec
EJB Time Out:- 300 sec
JTA Timeout:- 360 sec
If there is no setting of 30 sec then why my partner link is failing in 30 sec. Morever the intresting point is that although It is giving some Exception but it is performing the operations successfully. Due to this exception rest of my BPEL does not work.
Please provide me the pointer how to increase the Read time out and is there any relation between httpReadTimeout (Defined in composite for Partner Link) and syncMaxWaitTime.
Thanks In Advance,
Regards,
Lovenish

Invoking a AXIS Web Service with a Java object as input argument

Hi
I've been trying to execute a bpel process that invokes a web service deployed through axis.
This web service takes a java object as input argument as opposed to data types that are directly mapped to java types through the SOAP engine.
I deployed and tested the service outside of BPEL using a test client class. Everything works well.
When I try to configure the "Assign" and "Invoke" activities so that service can be invoked, I cannot see the data structure through the variable picker and I see the following message:
"The element {urn:ComplexTypeWebService}TimeSheetBean is not know to the schema container. Perhaps a schema file that uses it needs to include or import its definition.There mat also be an XML schema issue (non resolvable schema) which prevents {urn:ComplexTypeWebService}TimeSheetBean from being seen by the schema processor."
Is there any example that demonstrates how to invoke an axis web service in such scenario? What am I doing wrong?
Please, let me know.

The passing of Java objects in and out of a web service is NOT supported. variables must be xml documents defined by a XML schema. In my opinion, missing Java object and WSDL is not a good idea. -Edwin

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..

Invoking Imaging Web Service from BPEL is failing

Hi,
My Env is on latest 11g 11.1.1.8.

Invoking SWA web services from BPEL

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?
Edited by: 901765 on 12.12.2011 06:01

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!

Error in Invoking External Web Service in BPEL

Hello,
I have a Temperature Conversion Web Service deployed on an external server.
I want to invoke this Web Service in my BPEL process.
I got the wsdl loacation of the Web Service as "http://webservices.daelab.net/temperatureconversions/TemperatureConversions.wso?WSDL" and then in my workspace, I created a Web Service out of that WSDL.
My idea was to create a web service out of that WSDL and then to deploy that web service on SOA server so that i can invoke that deployed service in my BPEL process, but when i am creating a web service out of that WSDL , and trying to test the webservice in my local oc4j, i am gettting a fault exception.
Am i doing anything wrong ? Is there any other alternative to call a external web service in BPEL?
Thanks
Nutan

Hi,
you are on the wrong track....
Open your BPEL. Put the http://webservices.daelab.net/temperatureconversions/TemperatureConversions.wso?WSDL into a PartnerLink and wire an invoke against this PartnerLink....
Put the parameters via assign into the variables.
Done...
Why do you want to create an interal webservice and invoke this one via BPEL? Do you want to invoke the external webservice from the internal one?

Application Server 8.2 + Axis Web Service Client +Win Server 2003 Issue

Hi everyone,
I'm facing a weird problem the last couples of days and I'm getting bored of banging my head against the logs/screen, so please if you could help I'd really appreciate it.
I'm working on a Sun Application Server 8.2 project that includes an axis web service client. I am using Netbeans 5 to do the writing plus I am on a Win XP platform.
The developers of the web service I intend to absorb were kind enough to package the client into a jar so all I have to do is to import the client and the axis related jar files (axis, axis-ant etc.) in my project and my classpath.
Everything is working perfect on my pc but when I deploy the project on my actual server the web service client is running forever, leaving my end users with a blank browser window that is also loading forever.
The server OS is Win Server 2003 and is directly connected to a gateway - no proxies. Also my development pc and my server are running the same jre and have the exact server police settings; but Sun's Application Server is running on port 8080 on my pc whereas on my server it's running on port 80.
Here's my server's log:
[#|2008-04-14T21:50:01.795+0300|SEVERE|sun-appserver-pe8.2|javax.enterprise.system.container.web|_ThreadID=14;|StandardWrapperValve[obos]: Servlet.service() for servlet obos threw exception

Any ideas?

Hi Paz,
Thanks for taking the time :)
To answer your questions:
1. Has this WebServices ever worked or is this the first time?
The web service is working perfectly fine on my working station, the problem appears only when I deploy it on my actual server, which means that the web service is working.
2. What Apache Axis Version are you using?
1.4
3. What JRE version are you using?
Both my development pc and my server run jre 1.5.0_14
4. In the actual server environment, can you confirm all information are exactly same as DEV environment...
Oh yes! Absolutely.
My recent assumption is that some windows service might be needed to run the web service client and obviously I have no clue which one it might be.
Just to make sure; is the security policy of my Application Server set correctly?
     permission java.lang.RuntimePermission     "getClassLoader";
     permission java.lang.RuntimePermission "createClassLoader";
     permission java.lang.RuntimePermission "loadLibrary.*";
     permission java.lang.RuntimePermission "queuePrintJob";
     permission java.net.SocketPermission "*", "connect,accept,resolve";
     permission java.io.FilePermission "<<ALL FILES>>", "read,write,delete";
// work-around for pointbase bug 4864405
permission java.io.FilePermission "${com.sun.aas.instanceRoot}${/}lib${/}databases${/}-", "delete";
permission java.io.FilePermission "${java.io.tmpdir}${/}-", "delete";
     permission java.util.PropertyPermission "*", "read,write";
     permission java.lang.RuntimePermission     "modifyThreadGroup";
Again thanks for taking the time :)

Extra Tag Getting Added while invoking a Web service

Hi all,
We are facing an issue while trying to invoke a web service. We are assigning values to invoke input variable of the invoke. The issue is that while invoking an Extra element named “input” is getting added.
For Eg: The required one is
<messages>
<invoke_Webservice_Input>
Payload
</invoke_Webservice_Input>
</messages>
But what is getting passed is :
<messages>
*<input>*
<invoke_Webservice_Input>
Payload
</invoke_Webservice_Input>
*</input>*
</messages>
Due to this, the invoke is failing and we are not able to proceed. The error which we are getting is "*exception on JaxRpc invoke: unexpected null*"
If any has faced similar issues, please share your experience.
PS: The same wsdl is working in other environments. only thing we changed is the Endpoint URI and that endpoint URI is also accessible.
Thanks
Mohan

can u re import the wsdl into the process and then change the endpoint uri... undeploy the previous process.. bounce the server and then deploy the new process and try

Unexpected element name: expected error while invoking external web service

Hi,
In JDeveloper when I invoke external web service call, I am getting following exception
"unexpected element name: expected=..."
But the same application works fine in .NET. Can someone help me as to why I am getting the exception only in JDeveloper and how to fix this exception.
Thanks.

Hi,
Without more information, it will be hard to help, and tell you what could be teh issue.
Usually, this kind of error occurs when the payload and the WSDL schema are out of sync, for example if the order of the element on the wire do not match the order in a sequence declaration, you may get this error.
In such case, .NET handle the XML as if it was a 'all' -- no specific order -- and deserialize the message properly.
Hope this helps,

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.
