I also think that same way. I do not know what is so apecial about BEA Aqualogic ESB and other market matured ESB products such as TIBCO & SONIC. The samples which BEA has given in their evaluation guide are very simplistic. BEA should do more to provide extensive knowledge/features about their Aqualogic line of products.

Sun idm adapter for Enterprise Service Bus (Using MQ)

Hi
Can you please let me know if any sun idm adapter support Enterprise Service Bus (Using MQ) ?
Thanks

As answer on question 1:
No I never found any documentation from SAP that described a ESB solution. So al the knowledge must come from other vendors in your case from Sonic.
But there is hope you can use XI in a ESB way. You must only (add) configure the ESB parts. This is done by adding a service repository for example the UDDI server in combination with some BPML engine.
By adding it al together you can execute your business processes over multiple system platforms using SOAP in a synchronic way.
This is the basic concept of a ESB.
The answer to question 2.
I dont know if XI has build in support, but a know that there are free tools that can handle Canonical XML. So you can make a service your self to handle the Canonical XML documents.

How to call proxy service at enterprise service bus using flex

Hi
I have a proxy service located at wso2 enterprise service bus. How can i call that proxy service using flex?
Regards
Minal

Hi Minal, I think you can communicate with wso2 using mx:HTTPService or mx:WebService, you just need to find out which services you'll be consuming and then create the flex app to present and interact with those services.

SAP XI versus Sonic's Enterprise Service Bus

Hi,
Question 1:
In David Chappell's book 'Enterprise Service Bus', the Sonic ESB is described. He says that the ESB is more than a hub-and-spoke integration broker: ESB is a MOM and above that several 'generic' services, which handle the traffic and routing on the bus, for instance:
- Transformation service
- Content based routing service
- Orchestration service
- Splitter service
- Etc.
Is this concept adopted in ESA? If so how is this functionality implemented?
Question 2a: does XI uses xCBL as a XML-dialect?
Question 2b: does XI make use of the canonical-XML concept (by using xCBL) ?
Thanks in advance!
Greetings Theo

What is SAP ESB (Enterprise Service Bus)?

Hi fellow sdners gurus I have been reading threads about SAP SOA and ESB.
I do not want to start a debate on wether XI is an ESB, but more of a statement to what is SAP ESB (if XI it is, then be it).
1) What is SAP ESB (Enterprise Service Bus) today (I could not find a clear answer to is)?
2) Who uses this SAP ESB in production currently and what kind of environment (i.e. strictly SAP backend systems, or combination of various vendors backend systems)?
Can someone share some light on this topic?
As a reminder, an ESB is expected to exhibit the following characteristics (source Wikipedia):
     It is usually operating-system and programming-language agnostic; for example, it should enable interoperability between Java and .NET applications.
     It uses XML (eXtensible Markup Language) as the standard communication language.
     It supports web-services standards.
     It supports various MEPs (Message Exchange Patterns) (e.g., synchronous request/response, asynchronous request/response, send-and-forget, publish/subscribe).
     It includes adapters for supporting integration with legacy systems, possibly based on standards such as JCA
     It includes a standardized security model to authorize, authenticate and audit use of the ESB.
     To facilitate the transformation of data formats and values, it includes transformation services (often via XSLT or XQuery) between the format of the sending application and the receiving application.
     It includes validation against schemas for sending and receiving messages.
     It can uniformly apply business rules, enriching messages from other sources, the splitting and combining of multiple messages and the handling of exceptions.
     It can provide a unified abstraction across multiple layers
     It can route or transform messages conditionally, based on a non-centralized policy (i.e. no central rules-engine needs to be present).
     It is monitored for various SLA (Service Level Agreement) threshold message latencies and other SLA characteristics.
     It (often) facilitates "service classes," responding appropriately to higher and lower priority users.
     It supports queuing, holding messages if applications are temporarily unavailable.
Your help is greatly appreciated.
Kind Regards,
Jean-Michel

Create Oracle Service Bus using BEA workshop

Can someone please help with BEA Workshop developer guide/tutorial detailing how to create Oracle Service Bus using workshop IDE.
IDE - BEA Workshop 10gR3
OSB version - Oracle Service Bus 10gR3
Thank you

Thanks for your response Eric.
The tutorials that I've seen so far deal with OSB console, none of them talk about creating OSB using BEA-workshop.
On workshop IDE there is some help on OSB workshop plug-ins, but those are mostly one liners about the plug-in features
Please advice if you've link to OSB-Workshop tutorial.
Thanks

Publish BUS1065 object to Enterprise Service Bus (Tibco)

Dear forum members,
We are trying to find out if a concept we designed will work. Our goal is to publish a full business object e.g. BUS 1065 (Employee) to the Enterprise Service Bus (Tibco JMS technology).
We plan to customize change pointers to the BUS object, which will trigger a replicate of the BUS object. We hope to create an outbound iDoc which will contain the full BUS object. The ESB solution will trigger a JMS publish on receiving the iDoc.
Does anybody has experience with replicating a business object for a non SAP receiver? Will our concept work?
kind regards,
Richard

WLI as an Enterprise Service Bus (ESB)?

Hi!
BEA has previously sold WLI 8.1 as an ESB. See e.g. http://dev2dev.bea.com/pub/a/2004/12/soa_ibarra.html
Now that AquaLogic Service Bus has beed launched, it seems that the two products have much in common and some overlapping functionalities. E.g. both products have support for messaging and transformations.
For me it seems that the role of the two is not clearly defined.
What is new with AquaLogic Service Bus? What is the big difference? Why not just use WLI as previously described in the article by Ibarro?
Any thoughts? All input appreciated.

I also think that same way. I do not know what is so apecial about BEA Aqualogic ESB and other market matured ESB products such as TIBCO & SONIC. The samples which BEA has given in their evaluation guide are very simplistic. BEA should do more to provide extensive knowledge/features about their Aqualogic line of products.

Azure Service Bus client: Best way to wait for server response?

Hi,
I have a web service that needs to send a request on Azure Service Bus and wait for the response. The web service must operate synchronous as seen from the web service client, that is:
public Response WebServiceMethod(Request)
senderQueueClient.Send(Request);
// wait for response from receiverQueueClient
// and return to web serviuce client
return response;
This can be solved using mutexes that are updated in "receiverClientQueue.OnMessage". But that is hard work and if I Google the matter, I find several options to deal with this - especially when using .NET 4.5. And there are also some built-in
stuff in the QueueClient.
But how to do this best? Can someone point me in the right (easy) direction?
Werner

Hi,
May I know what are you use queue to achieve? can you give us further information for a better help.

Enterprise Service Bus

Dear All,
I was reading couple of article on what ESB is. But I was confused about the architecture of ESB. Does anybody have clear idea of what ESB is, what XI should provide to position it as a an ESB.
Please, do not point me to the sdn blogs/articles as I already them.
Thanks in Advance
Sreekanth

To share my understanding of ESB:
Any successful implementation of SOA/ESA requires applications and infrastructure to support it's principles. This means all the applications either should have the ability to expose their functionality as services or they need an infrastructure to expose the service. SAP XI would definetly help to expose the application functionality as services(web). I dare to call as a 'service container' in ESB terminology.
Besides the service repository functionality, XI also provides value added services like intelligent routing, mapping, auditing functionality etc.
And also distributed deployment(ESB quality for scaling) of some of the XI components are possible. Say for example, adapter deployment options(central, decentral), PCK, proxy framework etc.
On the security aspect of these exposed service, my understanding is that XI do not have much (like ws-security, xml signature, encryption, etc).
Business Process Modelling(BPEL4WS conformance) can be used for the service choreography. I am not sure whether CAF and VC supports BPEL standards.
Can anybody throw some thougths on this. And also what are the webservice management tools(deploying, declarative security etc) available in NetWeaver?
Best Regards
Sreekanth

Lion Server 10.7.4 VPN service not using my Active Directory domain for authentication

I have Lion Server 10.7.4 setup on a Mac Mini and I have enabled the VPN service for both L2TP and PPTP. The Mac Mini is joined to my Windows Domain at a functional level of Server 2008 R2. I have set the authentication paths to point to my domain in Directory Utility.
What I would like to have happen is for my laptop to be able to VPN into my office network remotely using domain credentials and not local account credentials on the Mac Mini itself. This is a process I have done numerous times on Windows boxes, but for some reason the only way I can get the VPN to work on this instance of Lion Server 10.7.4 is by authenticating using local accounts only.
Does Lion Server 10.7.4 only authenticate VPN users based on it's local account schema? Or can it truly authenticate against an active directory domain?
Any suggestions or help is greatly appreciated. Thanks,

Hi g-pirtle,
Yes, I had already done that a few days ago. I was able to add the desired AD group to the allowed users/groups for the VPN service. Thats exactly what is so weird about this...it allows me to search for and add an AD user or group to the list of allowed users/groups, but then when I actually try to use a domain account to authenticate to the VPN is just gives me the "cannot authenticate" error. Very strange.
I wondered if for some reason Apple is only allowing local accounts to be authenticated against. Sounds crazy, but I cannot for the life of me get this to work. I also wondered if Kerberizing the server would help, but when I go to join a Kerberos realm in Open Directory inside of Server Admin, it just has no realm listed in the drop down menu.
Other than that, all other aspects of the Mac Mini being joined to the AD domain seems to be good. I'm really stumped here...
Thanks again,

Synchronization of PCI devieces via the RTSI bus using the measurement studio for Viusual Basic 6

Hi everyone,
I would like to synchronize a NI 4474 A/D card with a NI 6733 D/A card via the RTSI bus. Is there any way of sharing the timebase using the measurement studio for VB 6.0? It seems like it could be possible using the traditional NI-DAQ .DLL but I would prefer to do it with the ActiveX API.
I am quite desperate, since all my attempts to use the CWDAQTools1.RouteSignal and CWDAQTools1.RouteRTSI command failed miserably :-(
Thank you very much in advance!
Federico

Thank you very much indeed!
Unfortunately it doesn't really work... I cannot use the DI options since my A/D card (NI 4474) does not support DI/DO... When using the other option (CWDAQTools1.RouteRTSI) I keep getting an error message that this command is inapropriate for my device (even though it does have a RTSI bus and allegedly it also supports time sharing...)
Looking forward to your answer!
Kind regards
Federico
