How to create RESTful proxy service in OSB?

How can I write RESTful web services in OSB?
We are using OSB 11g.
I know how to create SOAP proxy service in OSB. I just want to switch to RESTful services from SOAP.

Urgent ! Creating https proxy service in OSB

Hi All,
I am trying to create a proxy service with https(1 way) in OSB.I followed these steps,or rather tried.I am trying to use the default SSL keystores(Demo Identity and Demo Trust)
I made sure that the demonstration Identity and Trust keystores are located in the WL_HOME\server\lib directory and configured by default and the cacerts file in the JAVA_HOME\jre\lib\security directory.
But when I tried to create a service key provider in OSB I get this error "<There is no PKI credential mapper provider configured in your security realm. Service key provider management will be disabled. Configure a PKI credential mapper provider if you need service provider support. This is typically the case if you have Oracle Service Bus proxy services with web service security enabled or outbound 2-way SSL connections.>"
And when i try to create a PKI Credential mapper then I encounter this "This page is used to create a PKI credential mapping.
A PKI provider must be created and configured before a PKI credential mapping can be created."
Is there anything that I am missing?
Please advice ASAP.
Thanks

I have done this in my development server and it works fineOnly one service can listen on one port and hence you should assign unique ports to each server in Weblogic domain (including Admin server). Two weblogic servers cann't listen on one port. Make sure that ports assigned to the servers are not already in use by any other application/service including any other Weblogic server.
Please let me know for 2 way SSL,and to add the Service Key Providerhttp://download.oracle.com/docs/cd/E17904_01/web.1111/e13707/ssl.htm#i1200848

How to create asynchronous web services in OSB 11g?

Hi,
Using the workbench, when I try to create a web service from an existing WSDL, the workbench automatically uses JAX-WS.
JAX-WS does not offer support for asynchronous web services, since it supports only HTTP ports (@WLJmsTransport does not work).
Request your help in resolving this issue. One way is to use JAX-RPC but I do not know how to configure the workbench to use JAX-RPC instead of JAX-WS.
Thanking you in advance.

How to retrieve the java object in a proxy service in osb -- Plz help

Hi all,
I have a singleton java class which runs whenever the weblogic server gets started and store the output in its object. I need to access this java object from a proxy service in osb.
We tried using java call out and retrieved that object but we couldn't know how to parse that object into XML.
We are not sure of using the java call out in osb to solve this purpose because whenever we use a java callout, that particular java code will run which is not the case of singleton class.
So kindly help us how to retrieve the java object which holds the output without running the java code every time because its already run and holding the output in its object.
Regards
Prabhu

here the doc http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/userguide/context.html#wp1106656
but I guess you are already at the stage of getting a POJO in a first Java Callout and passing the POJO to a second Java Callout, which should then return it to OSB as a XMLObject.
My recommendation is to write a Java function which returns a XMLObject and uses a XMLCursor to populate it with the values of the POJO.
An XMLObject returned to the OSB is automatically transformed in a "XML" variable (which in reality is represented as a XMLObject in the Pipeline context)
Here some code sample:

Comment out actions in side proxy services in osb

Do any body know how to comment out certain actions in proxy service in OSB?
For eg: I have assign, insert, assign, ..route....
I want to comment out second assign but don't want to delete it, since i might need it later. Can I manipulate the generated code to comment?

What I meant is that I tried it with a very simple pipeline, a pipeline with one stage and one action. I added the comment tags around that action and it "disappeared" from my pipeline. Later I removed the comment tags and my action was there again.
But it could get complicated with a pipeline with many stages and actions (that's what I meant by complex). There could be dependencies between the actions (in one you create a variable that you use later in another action), etc.
I assume you're working directly on the web console. The files are stored in your server's file system but I really advise you against modifying these files directly.
With your installation of OSB you have an Eclipse (Workshop) with plug-ins for the OSB. You can export your project from the web console and import it into eclipse. You can work on eclipse and then publish your changes to the server.
There in eclipse you have your files in your file system and you can open them in your favourite text/xml editor. Or inside eclipse you can just right click on the proxy service and choose "open with -> text editor".

Proxy Services in OSB

Dear team,
Wehave a requirement to call a Wsdl based OSB proxy service with sb protocol from SOA Composite from BPEL process.
We created a wsdl based OSB proxyservice with sb protocol and deployed to OSB development server.
We tried to export the wsdl and corresponding xsd files. sbconfig.jar got created.
When we extracted the sbconfig file and placed the wsdl and xsd into the SOA composite.
When we are trying to create a partnerlink, that OSB proxy service wsdl is not showing up.
Please suggest.

OWSM user name token service policy for a proxy service at OSB

Hi Friends,
I am facing an issue while trying for the OWSM user name token service policy Authentication for a proxy service at OSB. I am using the PS4 SOA suite with AIA foundation pack. very first I am login into the EM console and choose the domain<soaosb_domain> form web logic domain I moved to security->security provide configuration. Inside the security provide configuration we have to key store section and I expand that and we have a configure button inside the keys tore. I click that button and it open a new page. In that page I got the Java key store (JKS) as the default key store and in the access Attributes I keep the default key store path and fill password and confirm password fields. Then in Identity certificates I fill the signature key and Encryption key with key Alias as 'orakey' and same password which I am mentioned at access Attributes. I got the message like the key store is created successfully. Then I restarted the server and again I am login into the EM console and choose the domain<soaosb_domain> form web logic domain I moved to security. In security I choose the credentials. In credentials we have create key. In the create key I add the key as hari-key and provide the hari as a user and his password.
While trying to test the proxy service i am getting the [OSB Security - OWSM: 387253] Failed to initialize OWSM Credential Manager. Please validate the Key store Configuration.
can anyone please look at this and suggest me how can I proceed for this.

Error while invoking web services from Proxy services in OSB

I have a Proxy Service of message type in Oracel Service Bus 10gR3 and it passes the incoming messages from a JMS Queue to Business Service of Web Services type. This Web Service is hosted in Glass Fish v3 and it's binding style is RPC. The JRE used in both the servers are 1.6.0_20. The JMS message is of Text type. The Web Services at the Glass Fish throws MessageCreationException for any content of the JMS message. However, it works fine if Business Service's test client is invoked from the OSB'S Admin Console. However, the same will not work if Proxy Service's test client is called.
The detailed exception stack is given below :

Let me explain what I am trying to achieve. Our application receives data from multiple sources - from mainframe using FTP, JMS Queue and BPM application using Web Services. The data from all these sources are sending to a Web Service running in GlassFish V3. To handle this I have created three Proxy Services and one Business Service on OSB. The Business Service is of type Web Service using the same WSDL from the target Web Service.
The Proxy Services are configured as follows:
Proxy 1 (type - Messaging service) listens to the JMS Queue and receives JMS Text Message -> Business Service(B1) (Web Service).
Proxy 2 (type - Messaging service Polls files from the FTP Server -> Business Service(B1) (Web Service).
Proxy 3 (type - Web service) is invoked by the BPM application and sends a String -> Business Service(B1) (Web Service).
All the Proxies route to the same Business Service - B1 which calls the Web Service in GlassFish. The only Proxy that works fine is Proxy 3 which is created using the same WSDL of the Web Service. In the other two proxies it thows the same exception in GlassFish as I mentioned before.
com.sun.xml.ws.protocol.soap.MessageCreationException: Couldn't create SOAP message due to exception: XML reader error: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog at [row,col {unknown-source}]: [1,0] at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:359)
Is this configuration correct to achieve my requirements?
Once again thanks for the help.

Using a uddi key to create a business service in OSB

I want to be able to use a service registry key when creating a business service in OSB. I've found documentation on how to do this in Oracle ESB, but not in OSB.
From the documentation for OSB, I can only find a way to synchronize the business services imported from the service registry (when i search through the imported services there is no mention of the uddi key that i can see). I can choose to auto-import when setting up the registry, but I'm not sure exactly what this behavior does.
From the console documentation (http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/consolehelp/uddi.html)
"You can use the Auto-Import Status page to synchronize changes to a service with those present in the registry. Upon any changes to a service in the registry, Oracle Service Bus provides notification of the change on the Auto-Import Status page which lists all out-of-sync services. You can then synchronize the service in the Oracle Service Bus Console with the corresponding service in the UDDI registry."
This setting seems to automatically update the endpoint of the business service wihtout that administrator having to do anything, but what is actually being done? Is the service bus updating the endpoint as soon as it has been notified of a change or when i view/call the service is the endpoint being looked up?
Am I missing something??

I took your advice and re factored the Receive class so it had all the functionality I needed except two methods which would then be overridden in the derived classes. What I had a hard time understanding is once an object of class say SpecialReceive extends Receive it can be referred to as Receive yet still maintain that it's a SpecialReceive.
What I mean is if I give a Receive object to some method and this method has no idea that this object is actually SpecialReceive and it calls a method say run() which gets overridden by the SpecialReceive. I thought that since this method has no idea what type of Receive this object is it will execute Receive's run(). But it actually does know what type of class it is and it executes the right run() method (the one that SpecialReceive overrides).
After I realized this there is no more need for casting.
Thanks everyone for your contributions.

Question: How to create a SOAP service?

I am working on a POC for evaluation of Aqualogic Service Bus 2.5. I am facing a difficulty in the following aspects.
1. I have a client on my system which reads a data service from DSP and gives a custom object in return.
2. There is a client on another system which has to use the returned custom object through a remote procedure call to my function.
3. I dont want to create a web service just for this purpose.
4. So I want that the object will be communicated to the other client in the form of a SOAP message and generate a response SOAP message which my first client will receive
I believe that Aqualogic Service Bus configuration of SOAP service will help me out in this case but i am not finding a way of doing this. I have been able to successfully communicate with web services configured in ALSB.
I went throught the document
http://e-docs.bea.com/alsb/docs20/consolehelp/businessServices.html
But it doesnt have the information of how to go about creating a soap service and configuring it in ALSB and then consuming it in a step by step manner. Please give me some techniques to achieve this.

First, try using the documentation here instead.
http://e-docs.bea.com/alsb/docs25/consolehelp/index.html
I did something similar with SOAP xml.
1) I had to create a wsdl file based on the incoming xml and
2) import it into ALSB (admin console). Creating the wsdl was the most difficult part for me.
3) Then you can create a proxy service (admin console) that uses the wsdl, and it'll allow accessing the proxy service as a web service.
