  • Best way to call web service from Message Driven Bean

    I'm q'ing msgs up and would like to use a message driven bean to forward them to
    an external web service. Weblogic workshop does not seem to support web service
    controls in an EJB project. Any suggestions?
    Thanks,
    Paul

    Paul,
    A non-trivial alternative, since you have the WSDL, would be to forget about trying
    to use generated client code and just use JAX-RPC dynamic invocation instead.
    That's how I call external web services from within an EJB in situations in which
    generated client code cannot be incorporated prior to deployment. Minimally all
    that is required is the WSDL and the service name, port name, and operation name,
    although if non-builtin parameter types are used then you will have to manipulate
    the service's type mapping registry.

    I've taken our wsdl and generated a web service in Workshop 8.1 using
    XMLBeans.
    This produces a web page that contains a link"Java Proxy" for downloading
    generated
    client code. I assume this is the same as clientgen. It's interesting
    that
    it does not
    use XMLBeans like the web service that generated it. It uses a different
    serialization
    method.
    I've used this generated code to call the web service. Although the
    client seems
    to run
    successfully to completion, I get the following error in the weblogic
    server console:
    <Sep 29, 2003 7:46:24 AM EDT> <Error> <WLW> <000000> <Failure=com.bea.wlw.runtim

    Hi Paul,
    Could you not first use clientgen on the external webservice, then take
    the stubs it created, then add these to your code along with the
    onMessage(Message msg) and roll it into the MBean?
    We don't have exactly that example, but you might take a look at this
    one to get some ideas:

    Bruce,
    Don't think this will work for us. We are receiving data internallythrough
    a JMS queue. We need to pull it off the queue (MDB), massage it alittle and
    send it to an external web service. The link you sent me was howto implement
    a web service with JMS.
    I started out by trying to use the Web Service and JMS controls butit doesn't
    seem like I can use a JMS control because that requires a conversationID,
    which we don't have because nothing is comming in through a web services.

  • How to access web service from Oracle ?

    Is there any ACL should be open in order to have this capability? I asked my DBA but she asked me I will need to give her username/password/ip in order to open an ACL...
    however there is no username/password required while visiting the web service...
    Any help would be highly appreciated..

So it could be a firewall on my database side that needs to be open in order to visit the hostserver?The "web browser" code (your PL/SQL code using UTL_HTTP) runs on the Oracle database server. It needs the same type of network access that your browser on your PC enjoys. (firewalls opened, proxy authentication if required, etc).
    On 11g. Not on 10g.I saw the example code you post through the link you provided... will those only work on 11g?
    If it can work on 10g, what package or what steps I need to follow in order to have that working on me?The code I've posted will work on both versions. My comment was regards to ACLs. No ACLs existed on 10g. So you only need execute privs on the relevant packages (e.g. UTL_HTTP, etc).
    ACLs were introduced with 11g - so on 11g you also need the DBA to create an ACL for you that will allow UTL_HTTP access to the network.

  • How to consume WEB SERVICES from ABAP ??

    Q: How to consume WEB SERVICES from ABAP program??
         the point here is i am using SAP release 620 and the creation of proxy is out of scenario
         and also no XI.    Its only through ABAP program i need to consume one web service (its a HTTPS one ),
        Using cl_http_client... i tried it but i am totally confused of whats happening ???
    Req some senior ppl advice on the same/approach.
    any hints will suffice my way of approach...!!!
    Please do put in your valuable advices..!!
    Thanks in advance..!!!!

    Hello Srinivas,
    Following is the code for calling web service:
    data: client type ref to if_http_client,
          host   type string value 'server url',
          service type string value '8080',
          path type string value '/sap/public/ping',
          errortext type string,
          proxy_service type string,
          scheme type i value 1.
    call method cl_http_client=>create
    exporting host  = host
            service  = service
         proxy_host  = host
       proxy_service = service
       scheme        = scheme
    importing client  = client
    exceptions
        argument_not_found = 1
        internal_error     = 2
        plugin_not_active  = 3
        others             = 4.
    case sy-subrc.
      when 0.
         write 'Server reached successfully'.
      when others.
         write: 'sy-subrc =', sy-subrc.
    endcase.
    Once you got the client object you can call following methods:
    "Set the requrie URL for the web service you want to call. This is not WSDL anyway!!
    cl_http_utility=>set_request_uri( request = client->request
    uri =' url 2 be called ').
    *Then you can call send method with proper inputs for sending request to WS
    CALL METHOD client->send
    Then you can use receive method for getting the response
    CALL METHOD client->receive
    *You can get last error in case of exceptions
    CALL METHOD cl_http_client=>get_last_error
    *Close the client object
    CALL METHOD client->close
    For more information on full code refer my link in previous replay.

    Hi Friend,
    How to call WEB Service From SAP 4.6 c Report
    Thanks in advance.

    It is not possible to directly call a web service from SAP 4.6c.
    Indeed, web service enablement is available as from Web AS 6.20, thus as from SAP R/3 4.7
    So as described above, the solution is indeed to make use of PI(XI) for this.

    Does any one have insights about it?

    Hi Swapna,
    from your screenshot it seems that you actually try to call the service in your Data Source Expression field. You should set path to the WSDL file here actually - this could be either URL to SAP or to filesystem, as Anton suggested (this could be faster). Have you created endpoint binding for your service in transaction SOAMANAGER? If yes, then simply download the corresponding WSDL with binding or copy the URL which leads to it. But also test whether you are able to retrieve the WSDL without logging into SAP (close all browser windows and then open a new one otherwise session ID from other browser windows can be reused).
    If you have to give username and password, then setup anonymous alias in transaction SICF, for example.
    Pleas, check my previous post on the same subject here: Re: BCM7 IVR : SOAP request for client identification in CRM .
    Maybe it could help.
    Regards,
    Dawood.

  • Web Service from stateful Session Bean deleted after server restart

    Hi,
    i created a stateful session bean and from this a web service.
    I am able to deploy it and it works really fine.
    My problem is: after a server restart the web service is gone and i
    have to deploy it again.
    I have some other web services (but these are web services from stateless session beans)
    but they "survive" the server restart.
    I don't want to deploy the web service after every server restart, did I forget something or
    is it a general problem of stateful session beans or web services?
    Thanks in advance
