I have created business and proxy services based on same wsdl file, and the wsdl has 4 methods for which i have created the branch node to call 4 methods, and in each branch node, i just used routing with option "Use inbound operation for outbound", as there is no data enrichment needed in OSB.
So this flow will accept the request and send the same request to my business service which i have created using same wsdl?
or
Do we need to modify the request and response XML to make this flow work?
If your osb architecture have only 1 layer based on same wsdl file, you don't need modify anything and that will work like simple pass route.
Option Use inbound operation for outbound means that your osb engine will use same operation in your business service.
The same result will be achieved when the checkbox is unchecked and the corresponding operation will be selected.

I am trying to create small Azure Logic app which will have some order flows.I will get the message in service bus queue. I need to get the message in logic app and based upon the message content, I need to follow the further steps. The message will contain the order data as well. There will be conditional logic, let's suppose, if order type is "new", I need to call HTTP request where I need to pass the message data as body content in POST request.
I have create a service bus queue and in logic apps, added service bus trigger which will be called when message will be received in service bus queue(automatically).
I need to able to implement conditional logic but as i am newbie in this, i am not sure how to pass this data in condtional logic from message.
You just need to mention the condition in the block and design the flow that we require. If the condition is true I have added the HTTP action mentioning the required details. For understanding purpose I have mentioned the other condition to trigger an email.
Here the flow of my logic app
If you want to continue the flow just click Add an action in True Connector.

In OSB Layer when the endpoint uri is changed, I need to alert the core group that the endpoint has changed and to review it. I tried SLA Alert rules but it does not have options for it. My question is, the endpoint uri should be saved somewhere in the underlying database. If so what is the schema and the table name to query it.
URI or in fact any other part of OSB artifact is not stored in relational database but rather kept in memory in it's original XML structure. It can be only accessed thru dedicated session management API. Interfaces you will need to use are part o com.bea.wli.sb.management.configuration and com.bea.wli.sb.management.query packages. Unfortunately it is not as straightforward as it sounds, in short, to extract URI information you will need to:
Create session instance(SessionManagementMBean)
Obtain ALSBConfigurationMBean instance that operates on SessionManagementMBean
Create Query object instance(BusinessServiceQuery) an run it on ALSBConfigurationMBean to get ref object to osb artifact of your interest
Invoke getServiceDefinition on your ref object to get XML service
definition
Extract URI from XML service definition with XPath
Downside of this approach is that you are basically pooling configuration each time you want to check if anything has changed.

There is also a good blog post describing OSB customization with WLST ALSB/OSB customization using WLST
The information about services and all its properties can be obtained via Java API. The API documentation contains sample code, so you can get it up and running quite quickly, see the Querying resources paragraph when following the given link.
We use the API to read the service (both proxy and business) configuration and for simple management.
As long as you only read the properties you do not need to handle management sessions. Once you change the values, you need to start a session and activate it once you are done -- a very similar approach to Service bus console.
How to pass the body without the tag to a Business service from proxy service route.. Just wanted the message to be routed to the JMS queue via business service. please advise.
You can use an XQuery transformation which will return the text message (without <soap:body>) that you wish to send to the queue. Have a replace activity (with replace entire node) using this transformation in your routing.
I am investigating ways to move data from SQL Server into system exposed via a RESTful HTTP API.
If I were to use SSIS would I have to write a custom connector to push the data to the HTTP API after the transform step, or is there a built in feature that supports pushing to an HTTP API?
If you only want to move a very small amount of data, you could use the Web Services Task
...but note that pushing data out of SQL Server is not what this task is intended for...
The Web Service task executes a Web service method. You can use the
Web Service task for the following purposes:
Writing to a variable the values that a Web service method returns.
For example, you could obtain the highest temperature of the day from
a Web service method, and then use that value to update a variable
that is used in an expression that sets a column value.
Writing to a file the values that a Web service method returns. For
example, a list of potential customers can be written to a file and
the file then used as a data source in a package that cleans the data
before it is written to a database.
For more control, you'll want to look at using the Script Component in a data flow. Much more flexibility/control.
I am using a WCF service between the Client side UI (Silverlight 3.0) and the Data Layer. We are using NHibernate for Database Access. So please tell me if my below understanding is correct or not:
UI calls WCF for a Save Method (for eg).
The WCF has a Save method in it which actually encapsulates a Save method from the Data
Access Object.
The Data Access Object method of Save in turn encapsulates a default Save Method of
NHibernate which actually saves some Business Object/s into the Database.
Also can someone tell me that how do we pass objects from WCF to the UI (Silverlight 3.0) layer and vice versa. I have read that we use DTO for that. But how does a DTO work? Do they correspond to the 'Data Contracts' in the WCF? If not then is the DTO declared on WCF (server) side and Client side code as well?
No, not quite....
UI calls the client-side proxy method Save
the WCF runtime takes that call and all parameters being passed in, and serializes them into a message (typically a XML serialized message)
the WCF runtime sends the serialized message over some kind of a transport media (whatever it is)
on the server side, the WCF runtime takes the incoming message
the message is deserialized, the appropriate class and method to handle it are identified
typically: a new instance of a service class is instantiated to handle the request
the WCF runtime unpacks the parameters and calls that appropriate message on the service class
same steps - basically backwards - are done for response
Important point: the only thing between the client and the server is a serialized message (which could be sent by e-mail or pigeon courier) - there's no other connection - no "remote object call" or anything like that at all
marc_s mentions the client-side proxies, which can be generated via the service references in your Silverlight project. The generated proxies are decent enough and provide an async model for running requests from the Silverlight side; those will look mostly like remoted procedure calls.
Another approach is to use the leaner (but maybe more advanced?) channel factory directly. A simple example of that can be found here. Both methods take care of most of the serialization details for you.
