How to call a C method with Java

Hi all,
is it possible calling a C method with Java?? And how to...?
thx for helping
Cobol1

is it possible calling a C method with Java?? And how to...?Not in general no.
You can use JNI which will call another C function (which you write) and which then calls your C method.
If the method is of a specific type (like OLE, Corba) then there are packages available which can allow you to access it. They still use JNI underneath, but hide that functionality from you.

  • How to call a AM method with parameters from Managed Bean?

    Hi Everyone,
    I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
    Class[] paramTypes = { };
    Object[] params = { } ;
    invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
    This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
    String aVal = "test";
    Class[] paramTypes = {String.class };
    Object[] params = {aVal } ;
    invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
    I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
    Thanks,
    San.

    Simply do the following
    1- Make your Method in Client Interface.
    2- Add it to Page Def.
    3- Customize your Script Like the below one to Achieve your goal.
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
    operationBinding.getParamsMap().put("username", "oracle");
    operationBinding.getParamsMap().put("role", "F1211");
    operationBinding.getParamsMap().put("Connection", "JDBC");
    Object result = operationBinding.execute();
    if (!operationBinding.getErrors().isEmpty()) {
    return null;
    return null;
    i hope it help you

  • How to call a static method in a class if I have just the object?

    Hello. I have an abstract class A where I have a static method blah(). I have 2 classes that extend class A called B and C. In both classes I override method blah(). I have an array with objects of type B and C.
    For every instance object of the array, I'm trying to call the static method in the corresponding class. For objects of type B I want to call blah() method in B class and for objects of type C I want to call blah() method in C class. I know it's possible to call a static method with the name of the object, too, but for some reason (?) it calls blah() method in class A if I try this.
    So my question is: how do I code this? I guess I need to cast to the class name and then call the method with the class name, but I couldn't do it. I tried to use getClass() method to get the class name and it works, but I didn't know what to do from here...
    So any help would be appreciated. Thank you.

    As somebody already said, to get the behavior you
    want, make the methods non-static.You all asked me why I need that method to be
    static... I'm not surprised to hear this question
    because I asked all my friends before posting here,
    and all of them asked me this... It's because some
    complicated reasons, I doubt it.
    the application I'm writing is
    quite big...Irrelevant.
    Umm... So what you're saying is there is no way to do
    this with that method being static? The behavior you describe cannot be obtained with only static methods in Java. You'd have to explicitly determine the class and then explicitly call the correct class' method.

    cast to java.lang.Object[] for a non-varargs call and to suppress this warning
    ms[0].invoke(o, null);
    ^
    1 warning
    Since the problem was with this line "ms[0].invoke(o, null);" and the specific point falls on the last argument as the warning mentioned that " ... method with inexact argument type for last parameter", I simply deleted the argument "null" and the line becomes "ms[0].invoke(o);" and it works, no warning anymore!

    Hi,
    You mean accessing ABAP functions from J2EE perspective, then I think we can do this by using SAP Java Resource Adapter and also through webservices.
    SAP Java Resource Adapter (SAP JRA) can be used as an add-on for the SAP JCo SAP JRA enables the implementation of standard interfaces from diverse J2EE servers to the SAP JCo in the SAP Web AS. The SAP JRA thus simplifies
    communication with ABAP within heterogeneous J2EE landscapes.
    Go through the following links which has Good documentation on how to achieve this

  • How to call jpf controller method from javascript

    Can any one help me how to call pageflow controller method from JavaScript.\
    Thanks.

    Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
    1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
    document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
    document.getElementById("batchForm").submit;
    2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
    document.getElementById("ACTION_NAME").value = "UPDATE";
    document.getElementById("batchForm").submit.
    Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
    3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
    This entire lines of code should do what we want.
    <netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>                    
    <netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
    <c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
    <%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
    <netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
    </c:forEach>               
    </netui:select>
    See if you can build along those above lines of code. Any other simpler approches are highly welcome.
    Thanks

    hi,
    1)    You can make the method EH_ONSELECT as public and static and call this method in viewGS_CM/ADDDOC  using syntax
        impl class name of view GS_CM/DOCTREE=>EH_ONSELECT "method name.
                 or
    2)The view GS_CM/ADDDOC which contains EH_ONSELECT method has been already enhanced, so I can't execute such kind of operation one more time.
                         or
    3)If both views or viewarea containing that view are under same window , then you can get the instance ofGS_CM/DOCTREE from view GS_CM/ADDDOC  through the main window controller.
    lr_window = me->view_manager->get_window_controller( ).
        lv_viewname = 'GS_CM/DOCTREE '.
      lr_viewctrl ?=  lr_window ->get_subcontroller_by_viewname( lv_viewname ).
    Now you can access the method of view GS_CM/DOCTREE .
    Let me know in case you face any issues.

    So why would the code we post be any different than the code in the tutorial? Why do you think our code would be easier to understand? The tutorial contains explanations about the code.
    Did you download the code and execute it? Did it work? Then customize the code to suit your situation. We can't give you the code because we don't know exactly what you are attempting to do. We don't know how you have changed to demo code so that it no longer works. Its up to you to compare your code with the demo code to see what the difference is.
