Transactional Web Services?
Is there any way to ensure that web services are transactional?
We have a rich client passing soap calls through to an OC4J container. We are certain that session beans are transctional, since if an error occurs in the database, the entire transction is rolled back.
However, if we pass the soap call through, and somehow a network connection is lost before the client receives the response from the server, we think because the transaction may be updating to the server, and since the client doesn't receive notification, it ends up thinking the transaction failed, and tries to send it again later. (thus failing later with a duplicate key) We're still trying to research this but so far this is what we suspect is happening.
So my question is, are OC4J web services transactional? Or is a limitation due to the stateless nature of http?
Jason,
Currently oc4j web services are not transactional in a sense, that they don't provide any transaction context propagation mechanism between the client and the server, etc. There are different evolving standards in the web service space regarding support for distributed 2pc and long-running transactions, such as WS-Coordination/Transaction. As the standards/protocols mature, oc4j will provide corresponding support for them.

But, whenever I am using the same URL in MII BLS, it does not give any error. It correctly shows all input and output parameters.
Please help me to resolve this issue.

Neeta.Now, I am able to create the Web Service in SAP and it is now showing the respective class, attribute and methods to execute this web service (web service to call MII transaction).
But when I am calling it from ABAP (a simple Web Dynpro for ABAP method), it is showing me the following error:

Thought this error is coming from ABAP program, but I am sure that this is related to some configuration at SAP level. (Let me inform you that there are two different servers for SAP Web Dynpro ABAP and SAP MII.

WebLogic 10.3.0, web-service enabled session beans, and CMT transactions
Does WebLogic 10.3 support CMT for JAX-WS Web-Service enabled EJB 3.0 session beans?

context.lookup( "java:comp/TransactionSynchronizationRegistry" );
registry.putResource("foo", "bar");
return param;
}WebLogic throws this exception:

at weblogic.transaction.internal.TransactionManagerImpl.putResource(TransactionManagerImpl.java:2033)
at weblogic.transaction.internal.TransactionManagerImpl.putResource(TransactionManagerImpl.java:2029)Is this a bug in WL 10.3.0?
Thanks in advance.
Edited by: user572625 on Aug 18, 2011 12:29 AMThis is fixed now. Someone had defined a Servlet for the web service in web.xml that was preventing the EJB container to kick in.

Error while calling web service through Internet Transaction Service.
Hi,
I am trying to execute transaction through web service. This service is attached to Internet Transaction Server (ITS). In Transaction SICF, in ITS when I test service, getting Error Message : New session rejected due to Memory bottleneck.
Thanks,
AnupHi,
you need to provide a better description of what you did (implementation) and what you want (use case). All I can see from your question is that you have a class cast issue.

Error calling BLS Transaction as Web service
Hi,
I am trying to call BLS tranx as Webservice from another BLS Tranx.
I craeted the simple BLS with no input parameter and set only one output parameter.
Then i created the WSDL as
http://<server:port>/XMII/WSDLGen/<Transaction path>.
In new BLS tranx, i created the Web Service action block and gave this WSDL URL (http://<server:port>/XMII/WSDLGen/<Transaction path>).
I gave username and password and selected the port(XacuteWSSoap) and then operation( xacute).
In Links, I gave the Loginname and Password.
But while executing, it showed the error as
Error Invoking Web Service Action: Status (401): Unauthorized
My username and Loginname and passwords are correct only.
What is the problem and how to solve it.

Which SAP MII version you are using?
I have tested one piece in MII 12.0.9 it works for me following are steps which i followed.
After WSDL generation
1. in Web service action block --> cofigure i am passing following parameters
WSDL base URL: http://<server:port>/XMII/WSDLGen/<transaction Path>
User Name: XXX
Password: XXX
2. in Web service action block --> Links I am passing following parameters
WSDLUrl : http://<server:port>/XMII/WSDLGen/<transaction Path>
Web_Service_0.XacuteRequest{/ns1:XacuteRequest/ns1:LoginName} : XXX

Error while calling MII transaction as web service
Hi all,
I am using MII version 12.1.8
When i try calling a BLS as a web service i am getting an error as " [ERROR] Error Invoking Web Service Action: Status (502): Proxy Error ( No data record is available. ) "
The same WSDLGen url is working from the browser. The path is http://<server>:50000/XMII/WSDLGen/<TrxPath>
I also gave Proxy Host and Proxy Port in System Management --> System Administration
Is there anything i am missing in the web service action.
Kindly help
Regards
MuzammilHi Diana,
It is working now. I removed the proxy settings from system administrator and added a new credential alias for web service. And then it started working..
The scenario which i am trying is as mentioned. We need to call a transaction from a diiferent MII Server. So at first i was trying with the Trx within the same server.
Hope this is the best way to access the transaction from a different server.

Create MII transaction & MII Web Service and consume them in ABAP
Hi,
there is a document from Pradip Ray (SAP Labs India) published on SDN:
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/208239ac-3161-2b10-f29a-abec6754942e
He explains how to build a transaction in MII, expose it as a web service then consume it in an ABAP program by generating a ABAP consumer proxy for this service.
I have done this and it works but the problems started when I tried to generate a second ABAP consumer proxy for a second web service build in MII.
In the ABAP system , transaction SE80 then display proxy class: ( e.g. ZMIICO_XACUTE_WSSOAP )
then go to Properties tab , under sub-screen "External key" you can see the "Name: XacuteWSSoap".
This is the web service port type name generated at MII and is always the same for all the MII web services. When you try to generate a second proxy for a second MII web service you get the following message "A proxy already exists for object XacuteWSSoap (namespace http://www.sap.com/xMII) "
This can be changed by editing the WSDL file but then another problem occurs which is related to the "InputParams" complex type. This tag gets generated with the same name for all the web services in MII. The generation of the ABAP structure with the following name: INPUT_PARAMS will override the previous one . This means that the previous ABAP proxy will not work anymore.
Has any one experimented this ?

</definitions>Hi Daryoush,
Little surprise for you, I got the solution ;o)
In fact, editing the WDSL file, you can change the parameter names which will be generated in Web Dynpro. You have to change the tag <complex type ...>.
For example :
<s:complexType name="InputParams">
Could become :
<s:complexType name="*Zs1*InputParams">
and later in the code, you should reference the element appropriately
<s:element maxOccurs="1" minOccurs="0" name="InputParams" type="s0:InputParams"/>
should become :
<s:element maxOccurs="1" minOccurs="0" name="InputParams" type="s0:*Zs1*InputParams"/>
But take care to keep name="InputParams", it's the xlm name which will be used by MII to do the matching...
Take care also that you have to do the same for output, that means ROW and ROWSET complex type...
So, to be concrete, here are an example with in bold everything I changed against the original MII WDL file...

How to control transactions (WS-AT) between two web services in OSB?
Could someone tell me if the OSB can have 2 diferents web services controlled by an unique transaction?
For instance: in the OSB there are two wsdl, each one with its own Business Service and ProxyService respectively. In my vb.net aplication I started a transaction, called the first web service succefully and from the second web service I got an exception. I expected the first web service undo its work because the vb.net aplication excute a rollback command. Is this possible? How can I do? Any sample or tip will be helpfull.
If I was developing without OSB, I would rely on WS-AT as shown in http://www.codeproject.com/Articles/38793/6-Steps-to-Enable-Transactions-in-WCF for two web services dot net, or for one web service dot net and other java, http://www.ibm.com/developerworks/websphere/library/techarticles/0707_lo/0707_lo.html.
My question is basically: Is still possible to keep a single transaction between multiple web services when they are mediated by OSB? If so, is there a example showing how?Hi,
When you create the proxy server, you have to check "Transaction required" box on Message Handling page...

Creating a Web Service Proxy for a transaction with Microsoft Visual Studio
Hi experts out there,
I have created a simple transaction which I'd like to call as a webservice. Getting the WSDL from an authenticated browser (from which I started the xMII Workbench) works fine. But when I try to create a Web Reference within my Visual Studio project I only get the following output:
"XacuteWS" Description
Methods
Xacute ( LoginName As string , LoginPassword As string , InputParams As InputParams ) As Rowset
I think this is because my visual studio is not authenticated with the xMII server. So is there any way to achieve this? I have to find a way to generate a .NET proxy for out xMII web services because otherwise it would be too complicated to use the web services from within our .NET applications.
Thanks in advance for any hint on this topic!
AchimTwo comments:
1) The generated proxy looks correct. If you explore the generated code for the InputParams object and the Rowset object, they should represent the incoming and outgoing data structures for your transaction. If not, and if you are returning an XML property type from the transaction, be sure that you have used the "Assign Reference Document" technique to tell MII what the structure of your outgoing document is (there are a few other discussion threads on that topic).
2) Personally, I find it much easier to consume MII services from .NET code using a URL-based technique instead of a SOAP based technique. Invoke the "Runner" servlet (see the documentation) and you'll get an XML document back, that will always be in the MII Rowsets/Rowset/Row format. Also, it is "self describing" because it includes Column metadata information. It is very trivial to load this into a .NET XmlDocument object and parse/process it. In fact, doing a similar approach, I've been able to make MII services appear as ADO.NET tables/stored procedures to .NET code.

Database transaction management in Web services
Hi,
I am using Oracle8i and firing some database queries from my web services. I want to do the transaction management for the same i.e. When one of the queries fail, i want to rollback. But when i write my own transaction management, it gives me an error :
java.sql.SQLException: Cannot call Connection.commit in distributed transaction.Transaction Manager will commit the resource manager when the distributed transaction is committed.
Can anyone please help me out as to how to perform the database transaction management in web services.
Thanking in advance.
PrashantUnfortunately to manage transactions over web services there is no viable solution available in market. All implementations come with restrictions e.g. Metro works with only EJBs on Glassfish, JBossTS works on JBoss but not with JAX-WS, Atomikos supports only Axis as of now.
1. See explanation above.
2. Yes, it can be but conditions mentioned above are applied :-)

ECC-6.0 supports XA(Distributed Transactions)&WS-AT(Web Services u0096 Atomic)
Hi
1- Does SAP ECC-6.0 support XA transactions?
XA Transactions stand for (Distributed Transactions).
2- Does SAP ECC-6.0 Web services allow participation in WS-AT?
WS-AT Stands for is Web Services Atomic Transaction specification.
If so please provide the referral point where I can get the Documentation regarding this.
Any earlier reply will be rewarded.Hi
1. What is meant by XA ?? Please clarify.. I guess, ECC should support..
2. Yes...
SAP supports ATS... Atomic Transaction specification defines protocols that is recognized by SAP. This failure atomicity property is supported by atomic transactions, which have the following familiar ACID properties.

Does BPEL Server have support "Web Services Transactions specifications"?
The Web Services Transactions specifications define mechanisms for transactional interoperability between Web services domains and provide a means to compose transactional qualities of service into Web services applications.
Have anyone can explain oracle process manager have any support about "Web Services Transactions specifications" ?
or oracle BPEL process manager how to coordinate the actions of distributed applications. Such coordination protocols are used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed activities.
appreciate any idea for this issue, thanks a lot.You have a number of options. You can use the built in Screen Sharing application, you can purchase Apple Remote Desktop for each user, you could look at 3rd party tools like GoToMyPC or if you are looking to replace Terminal Services look at AquaConnect.
The tool you use will be determined by what the users have at home. If they are also using Macs, they can use all the native tools. If they are on PC, they can use either a VNC client or many of the 3rd paty tools. -
MII transaction as Web service integration
Hi MII's transaction can be called as WS but it has its own format. We have a system to integrate and this system should call MII's transaction. However the WS interface of the system is inflexible (it cannot be change, but has a very simple structure). So I just want to know any idea how we could change MII in order to adapt to the data structure .
Now, I am able to create the Web Service in SAP and it is now showing the respective class, attribute and methods to execute this web service (web service to call MII transaction).
But when I am calling it from ABAP (a simple Web Dynpro for ABAP method), it is showing me the following error:
Error (id=GET_BUSINESS_SYSTEM_ERROR): An error occurred when determining the business system (LD_ERROR)
Thought this error is coming from ABAP program, but I am sure that this is related to some configuration at SAP level. (Let me inform you that there are two different servers for SAP Web Dynpro ABAP and SAP MII.
Please help.

Disabling transactions from WLI Workshop Web Service application?
I need to disable the transactions from a Workshop generated Web Service for WLI (Workshop 8.1.6).
I can accomplish this by changing and repackaging the builded EAR-package by altering the ejb-jar.xml:s in the .workshop directory and setting the transactions from Required to NotSupported. It would be much more convenient, if I could do that change from the Workshop.
Actual question: is there a way to disable transactions from a Web Service in Workshop? I have not found any place to change this property.Hi
You have 2 options.
As you mentioned you can modify the generated ejb descriptors. Unfortunately this attribute is not exposed as a property in the workshop, so you cannot change there.
Other option is to suspend the transaction created by workshop so that your webservice functionality or any control called within that won't be part of the workshop transaction.

If this really is a delivery for stock/inventory items there should be a journal entry, else it sounds like an error in SAP.
Are there still changes in the stored procedure? Also have a look at the TansactionNotice. It is possible the roll back does not work correctly.
Again sounds like an error.
Doe sit happen all the time?
Only for certain items?
Are the stored procedures now clean?
What Version are you using?
Kind Regards,
Friederike
