Proxy Services in OSB

Hi All
I have an small confusion regarding Proxy services in OSB. Do we have to create a Proxy service from some wsdl file only or can we create a proxy service without a wsdl in OSB and If yes then how to invoke it from BPEL process.
Thanks,

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".

Can anyone help me what is the use of business and proxy service in osb?

Hi,
I am new in Osb what is the use of business service and proxy service in osb.
I know little bit proxy service is used for actual message flow. I saw some project proxy service invoking the (using service callout,routing and publish) service,but the wsdl of the services of the proxy and business service is same.
Please can anyone explain the flow while executing through soapUI?(that means it will hit 1st business services or proxy service)
I have this project structure
business service
1.reference.biz----> this is the wsdl of ex:reference.wsdl
2.external.biz----> this is the wsdl of ex:external.wsdl
proxy service
1.referece.proxy--->this is the wsdl of ex:reference.wsdl(in this proxy we are routing to reference.biz proxy service both contains same wsdls why?)
xqueries of request and response.
Best Regards,
Raju.

Hi Raju,
Proxy Service - It is the starting point of you OSB application which deal with receiving messages, inducing logic in it like transformation, if-else, replace, java call outs,etc. You can put in your program logic here and then invoke a business service to route it to your Database or to any other queue as per your requirement.
Business Service - It is generally used for routing purposes, like inserting the input in your Database or sending it to a different queue or BPEL process, etc..

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.

Need JAVA API to list down all the Proxy Services in OSB Console 11g

Hi,
I need a java API to List down all the Proxy Services present in OSB Console for SOA 11g (11.1.1.5). I am in a situation where I cant use python script for the same.
any help will be much appreciated.
Thanks in Advance,
Ravi
Edited by: 899443 on Oct 1, 2012 4:13 AM

AFAIK it is proprietary.
What I do in a similar situation is to form XML for the services, package them into JAR the same way as an import JAR is packaged (creating ExportInfo resource, ...) and deploy with standard WSLT script. Works for simplest services only (direct proxies mostly) but I can also form security, alerts, throttling etc etc etc -- all in one shot.
Out of sheer interest, may I ask you a question? Why do you need to create OSB services from Java?

How to use "Routing Table" option in Proxy service in OSB ?

Hi,
I have created Business and Proxy services in my OSB console. I have used "Custom Query" option while creating the Database Adapter and I'm passing one input parameter to the query. My input parameter is "Name".
Based on the input values for this parameter, I need to pass a corresponding values to the query. For example, If I pass the following values to "Name" input parameter (India) I need to pass "Value1" to my query -
India --> Value1
China --> Value2
America --> Value3
To achieve this requirement, I have used "Routing Table" option. I have specified the values as follows -
Expression - $body/fet:FetchCustDataInput/fet:Name
Operator- '='
Compare value - India
Service - "My Webservice"
Operaton- "My Service Operation"
In the "Request Actions:" I have added the "Add an Action --> Messaging Processing --> Replace" and provided the following values -
Replace <XPath> = $body/fet:FetchCustDataInput/fet:Name
in Variable = "Name"
with Expression = xs:string('Value1')
and selected "Replace node contents" option.
No validation errors I faced. I have created the Routing table in Proxy service. But when I try to execute the proxy service in my Test Console, I get the following error message -
"The invocation resulted in an error: Unknown error while processing message for service ProxyService OSBQueryService/FetchByCustomQuery/FetchByCustomQueryPS."
I have even enabled "Direct call" and "Include Tracing" options as well. The message under "Tracing" give "(echoing request)
Routed Service. No Service has been invoked, the request is echoed.".
Can anyone please help me to resolve this issue.
Thanks in Advance,
Udaya

Did you put any loggers in the proxy at request pipeline prior to route node ? Can you trace if the request has entered request pipeline aleast.
If not just check the transport headers under the request window in the test console. There should be a text box for entering username/password which should be left blank. I have faced this unknown exception from test console in some browsers where an incorrect username/password used to get populated here. Check this ..

Unable to poll for files in FTP server using Proxy Service (in OSB Project)

Here are the stepd followed for creating proxy service that should poll ftp server to retrieve files but polling is not happening and unable to see any errors in logs.
1. Created service account by selecting resource type as static and providing the ftp user and password details.
2. Created a New Proxy Service in eclipse
     Tab General - service type as Messaging Service
     Tab Messaging - Request Message Type as Text, Response message type as None
     Tab Transport - Protocol selected as "ftp"
          - Endpoint uri entered in the format - ftp://hostname:port/directory
FTP Transport -Selected "external user" as User Authentication
          - Selected the Service Account thats created in step1/
               - File mMask - *.*
               - Polling Interval 60
               - Read Limit 10
               - Post Read Action - Delete
               - Transfer mode - binary
               - Download Directory - "some local directoy"
               - Error Directory - "some local error directory"
Could any one please help here to trouble shoot the polling issue and correct me if this is wrong approach.
Thanks

Did you configure the FTP adapter which is present in Weblogic server?I think he's using FTP transport in OSB and not the JCA adapter, if that's the case FtpAdapter configuration wouldn't help...
unable to see any errors in logsThat's odd, try to mess up the hostname and see if you get a connection refused on the logs...
It may be a permissions issue, the user you're connecting may not even "see" the files you place there... Try using the same user to create and to poll files...
Cheers,
Vlad
