Best way to call oracle db from BPEL 2.0

Hi
Anybody knows which is the best way to call select or call store procedures from BPEL 2.0 ? Do I need to use JCD (java collaboration definition in repository-based projects -caps 5.x) and oracle eWAY to interact with oracle database?
Regards.

You can also create a new WSDL with a concrete binding to DATABASE, as explained on http://wiki.open-esb.java.net/Wiki.jsp?page=CreatingAWSDLDocumentForTypeDATABASE

  • What is the best way to call a servlet from another servlet?

    I have a project with 9 servlets (class project). The way I have been moving from servlet to servlet is like this
    doPost(...)
    {      response.setContentType(CONTENT_TYPE);
    PrintWriter out = response.getWriter();
    out.println("<html>");
    out.println("<head><title>Functions</title>");
    out.println(f"<form name=frm6 method=post action=/servlet2");
    out.println("<input type=submit name='btn' value='servlet2'>");
    out.println("</form>");
    So I have these 9 servlets - I call any 8 of them from the first servlet so I have 8 buttons on 8 forms <form=frm1, frm2, ...frm8 method = post...> But when I bring up the first servlet only 6 buttons show up. I was thinking about using hyperlinks instead, but I would like to do this with buttons. I wanted to do this with javascript and the location object, but I was advised to use jsp. I just want to move from one servlet to the next. Any suggestions appreciated for the best/preferred method for moving from one servlet to the next.
    Thanks

    I think you may need some clarification of terminology etc..
    First off, JSP isn't an alternative to javascript, it's an alternative to coding a servlet. A JSP is a mixture of java code and HTML and is translated into a servlet by the system. JSPs are primarilly for generating HTML pages with variable content. JSPs very frequently generate HTML which includes Javascript.
    You probably shouldn't think of what you're doing as one servlet invoking another, that does happen; a servlet can transfer an transaction to another servlet or JSP. In fact it's standard practice that a servlet does the logical stuff (like interpretting form data) then transfers to a JSP to generate the response page. However in this case it's the browser that can invoke one of the 8 servlets, the first servlet merely creates the page from which they are invoked.
    It's not obvious why only some of your buttons are showing up. In a case like this use the "view source" option on your browser to find out what HTML the servlet is actually delivering. What's wrong should be evident from that.
    You can put a hyperlink arround a button, or an image. Mostly people turn up their noses at the buttons supplied by HTML and use their own images for buttons. You
    can do somthing like this:
    <img src="/images/button3.png" border="0">
    (Of course this arrives as a GET transaction not a POST).
    Or you can do a bit of javascript like:
    <img src="/images/button3.png" style="Cursor: pointer;"
    onclick="document.locations.href='/servlet3';">

  • 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,
    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

    This produces a web page that contains a link"Java Proxy" for downloading

    that
    it does not
    use XMLBeans like the web service that generated it. It uses a different

    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

    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:

    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.

    You can use RUN_REPORT_OBJECT with CACHE type, and WEB.SHOW_DOCUMENT to view the document on the screen.
    In the Forms help you should find examples.

  • Best way to call EJB - Servlet or Tag Library

    Hi,
    What is the best way to call an EJB from a JSP? We are using Weblogic 7.0(moving to 8.1 beta). WE have a form on a JSP that needs to get data from an EJB. Our flow goes from JSP --> Controller servlet or tag library -->EJB "Bean" Controller ---> EJB. The specfic EJB we need to populate drop downs and fields will be called by a bean controller. Is it better to call the bean controller using a tag library in the jsp or go to the controller servlet to get the data? If servlet is the answer, where do I lookup the EJB Home and call the create from within the servlet? Any help would be greatly appreciated!!
    Thanks!

    IMO, if you are following some design patterns, like the MVC framework, the best thing is to populate the model(entities that contain the business data) and call the respective getXX methods from the model on the JSP page. The reason for doing so is to keep JSP pages away from any other work other than to just display the business data contained in the respective business entities.
    The model can be populated in the servlet and either set in the request or session attribute as per the requirement.
    The EJB can be looked up in the servlet as and when required. I would suggest to make use of the Service Locator Pattern to do a look up for the EJB Remote Interface and accordingly make the business calls.
    Hopefully this answers some of your questions.

  • Best way to retreive an attributeValue from the bindings in a backing bean?

    What is the best way to retreive a value from an interator in your data bindings inside a backing bean?
    I can come up with a way were i resolve the value of an expression like #{bindings.myAttribute.value}
    Is this the best way or is there an easier?
    I can also place a hidden inputField were i bind the value to the attribute in my bindings and set the bindings of the input field to my backing so i can just call the .getValue in my backing bean...

    Yannick
    What is the best way to retreive a value from an interator in your data bindings inside a backing bean? Using JDeveloper 11.1.1.3.0 I created an example application
    at http://www.consideringred.com/files/oracle/2010/Thread1665841AttributeValuesApp-v0.01.zip
    It illustrates the behaviour for 3 different approaches to get an attribute value in a managed bean:
    public class WithAttributeValues
      public int getMyIdFromEL()
        return (Integer)ELHelper.get("#{bindings.myId.inputValue}");
      public int getMyIdFromAttributeBinding()
        BindingContainer vBindingContainer =
           BindingContext.getCurrent().getCurrentBindingsEntry();
        ControlBinding vControlBinding = vBindingContainer.getControlBinding("myId");
        AttributeBinding vAttributeBinding = (AttributeBinding)vControlBinding;
        return (Integer)vAttributeBinding.getInputValue();
      public int getMyIdFromIterator()
        BindingContainer vBindingContainer =
           BindingContext.getCurrent().getCurrentBindingsEntry();
        DCBindingContainer vDCBindingContainer = (DCBindingContainer)vBindingContainer;
        DCIteratorBinding vDCIteratorBinding =
           vDCBindingContainer.findIteratorBinding("findSomeMyRowsIterator");
        Row vRow = vDCIteratorBinding.getCurrentRow();
        return (Integer)vRow.getAttribute("myId");
    }For some reason the approach using getMyIdFromIterator() does not behave as intended when navigating the current row.
    see screencast at http://www.screencast.com/t/nIJ3DpsNE9Y
    Maybe John Stegeman can explain why that is because it is basically the same approach as he suggested in this forum thread.
    But if you don't have an attribute binding because you only use the iterator... Is it an option to create an attributeValue and bind it to the iterator so you can use it in your backing bean that way? Based on my findings above, using attributeValues bindings seems to be preferable.
    or is it only possible when you realy have an inputField bound to the attributeValue? The example application in Thread1665841AttributeValuesApp-v0.01.zip does not have any af:inputText components.
    Your question about "the best way" made me wonder if that wouldn't require JSR 227 API, so I posted that question in another forum thread, "How to get an attribute value using JSR 227 API ?"
    at How to get an attribute value using JSR 227 API ?

  • Best Way to port the data from one DB to another DB using Biztalk

    Hi,
    please suggest best way to move the data from one db to another DB using biztalk.
    Currently I am doing like that, for each transaction(getting from different source tables) through receive port, and do some mapping (some custom logic for data mapping), then insert to target normalized tables(multiple tables) and back to update the status
    of transaction in source table in sourceDB. It is processing one by one.
    How/best we we can do it using  bulk transfer and update the status. Since it has more than 10000 transaction per call.
    Thanks,
    Vinoth

    Hi Vinoth,
    For SQL Bulk inserts you can always use SQL Bulk Load
    adapter.
    http://www.biztalkgurus.com/biztalk_server/biztalk_blogs/b/biztalksyn/archive/2005/10/23/processing-a-large-flat-file-message-with-biztalk-and-the-sqlbulkinsert-adapter.aspx
    However, even though a SQL Bulk Load adapter can efficiently insert a large amount of data into SQL you are still stuck with the issues of transmitting the
    MessageBox database and the memory issues of dealing with really large messages.
    I would personally suggest you to use SSIS, as you have mentioned that records have to be processed in specific time of day as opposed to when the
    records are available.
    Please refer to this link to get more information about SSIS: http://msdn.microsoft.com/en-us/library/ms141026.aspx
    If you have any more questions related to SSIS, please ask it in
    SSIS 
    forum and you will get specific support.

  • Best way to call

    which is the best way to call a scotland mobile phone from skype? i been using pay as u go credit and its 8 cents a min and was wondering if a monthly thing or a subscription is the way to go

    Translation patterns are for internal use to manipulate a number and then a route pattern will be responsible for pushing it out the gateway or some other method.  If this DID is still being sent to you you could either manipulate this at the CUBE and hairpin it backout or send it to CUCM and hairpin it back after it gets translated with a translation pattern out a route pattern.  I would recommend doing everything at the gateway unless you want to keep some record that the number is in use which CUCM can do more effectively.
    This DID being used for a fax is elsewhere offnet at this point I take it?  Make sure you have the proper CSS's and partitions set for hair pinning if you do this on CUCM since by nature forwarding to external numbers is disabled by default (or at least it used to be as I recall).

    - call your form from a client you did not tell us (probably APEX?!?)
    For the case you really meant to call a form within Database PL/SQL: Just in case you didn't recognize it, but the database is perfectly capable of PL/SQL and as calling a form within a database process is a one-way street as you cannot interact with it there is no point at all in writing the things you want to do in forms. If you want some PL/SQL code executed on the database then...well...put it in a stored procedure in the database!
