SAPEVENT - Calling a method

Hello everyone,
I am trying to call a method from my HTML and I need to pass my method some parameters from my HTML page.(my HTML page is rendered by XSLT and displayed in the CustomerFactSheet tab/HTML control in CIC) .
Currently, I use the SAPEVENT, which allows me to pass the BP number successfully.
Can anyone tell me how to pass other parameters (such as begin and end dates) in my SAPEVENT; or suggest another better way to call a method from the HTML code in the HTML control?
Cheers,
Tania

Hello Vijaya,
Thanks for the reply, but this doesn't solve the problem.
The HTML Viewer is in SAP WinGui and not in a PCUI application.
As far as I can see it, the problem simply lies in the SAPEVENT Handler in HTML Viewrer; it only supports 4 parameters:
- OBJECTTYPE
- OBJECTID
- LOGYSYS
- CALLERID
What if one needs to pass another parameter?
Can anyone recomend links/documentation around this topic (SAPEVENT, Context Menu)?
Cheers,
Tania

AutomationException while calling a method

Hi all,
I've got a problem accessing a COM/DCOM component in a Win2k box (Advanced Server)

Generically calling a method on an object

Hello,
I am trying to write a small utility method to generically call a method on an object.
This is what I have.
    public static void doCall(Object o, String methodName, Object ... args){
        Class[] types = new Class[args.length];
        int i = 0;
        for(Object arg : args){
            types[i] = arg.getClass();
        try {
            Method m = o.getClass().getMethod(methodName, types);
            m.invoke(o, args);
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error dynamically calling method " + methodName + " on " + o.toString());
    }It doesn't work because it can't find the method. If I hard code the parameter types as "new Object[] {Double.TYPE}" it works fine (on methods that take a double).
So, my question is, how can I generically set up the parameter types based on the types of the arguments?
Thanks,
~Eric

The problem is not on calling agr.getClass(), your primitive double is already autoboxed to a Double object. It is the doCall(...) method who expects an object, not a primitive. So when giving it a primitive value, java autoboxes it to the corresponding object type.
This means your attempt will only work if the methods to call do not have any primitives as parameters.
Test this code:
public class GenericMethodCaller {
     public static void doCall(Object o, String methodName, Object ... args){
        Class[] types = new Class[args.length];
        int i = 0;
        for(Object arg : args){
            types[i++] = arg.getClass();
        try {
            Method m = o.getClass().getMethod(methodName, types);
            m.invoke(o, args);
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error dynamically calling method " + methodName + " on " + o.toString());
     public static void main(String[] args) {
          Callable callee = new Callable();
          callee.callabelMethod(10d);
          GenericMethodCaller.doCall( callee, "callabelMethod", 10d ); // 10d gets autoboxed to a Double object.
class Callable {
     public void callabelMethod(Double o) {
          System.out.println("callabelMethod(Double o) called");
     public void callabelMethod(double o) {
          System.out.println("callabelMethod(double o) called");
}The output will be:
callabelMethod(double o) called
callabelMethod(Double o) called

Calling a method on backing bean in response to contextual event

Hi
I am using Jdeveloper 11.1.1.6.0 and using ADF contextual events..
I have a drop down list and i am rasiing a contextual event on changing the current selection. In response to that event i want to call a backing bean method with parameters.. But when i click on the subscriber section for the contextual event, i can see only some bindings of the page.. How can i call a method on backing bean as a subscriber..
Thanks
Raghu

Hi,
this article has a use case for the POJO approach: http://www.oracle.com/technetwork/issue-archive/2011/11-may/o31adf-352561.html
Another is to define a method binding in the receiving PageDef file and configure it as explained here

Any way (event) to call Java method after view created in JSF 2.0

Hi,
I am using JSF 2.0 Mojarra's implementation.
I am interested to know if there is a way to call Java methods before and/or after view has been restored.
I wanted to initialize data for my page in this Java method.
I could see there is an event class PostRestoreStateEvent added in JSF 2.0. How to use it?
I tired to use f:event element as below, but it does not work. Can anyone share anyother idea to achieve this behaviour?
<f:metadata>
<f:event type="postRestoreState" listener="#{employeeLoadBean.loadAfterRestoreView}"/>
</f:metadata>
Regards,
Kishore K S

Hi,
The problem is solved as below.
<f:metadata>
<f:event type="javax.faces.event.PostRestoreStateEvent" listener="#{employeeViewEventListener.postRestoreState}"/>
</f:metadata>
The above calls the Java method #{employeeViewEventListener.postRestoreState} whenever View has been restored.
It was not working when shortName of the event (ie., postRestoreState) is given and throwing ClassNotFound exception.
Regards,
Kishore K S

Hi,
When you use the database value directly in your BDC, you will have this issue. It is always advisable to use character fields when doing BDC. so change it to charecter field and try it..

How to call a method in one JSP from another JSP?

say that I have 2 JSPs.
JSP one has a button.
JSP two has some method that, say, find the square root of the number passed from JPS one.
How to - when click - the button on page one call the method on page two?
Please note that I can not use object binding, but I want passing the actual parameter and call the method on page two.
Please note that this is an update of a previous post on the same topic called "Object scope".
Thank you all very much.

No, i dont know how to call other than main methods from other classes
And one more doubt i have i.e. Like in C can we see the execution of the program like how the code is being compiled step by step and how the value of the variable changes from step to step like(Add Watch).........

Is it possible to call a method in a servlet from a java script ?

I need to do a dynamic html page . In the page i select some things and then these things must communicate whit a servlet because the servlet will do some DB querys and update the same webpage.
So is it possible to actually call a method of a servlet from a java script? i want to do something that looks like this page:
http://www.hebdo.net/v5/search/search.asp?rubno=4000&cregion=1011&sid=69DHOTQ30307151
So when u select something in the first list the secodn list automaticly updates.
thank you very much

You can
1. load all the options when loading the page and
set second selection options when user selected
the first; or
2. reload the page when user select first selection
by 'onChange' event; or
3. using iframe so you only need to reload part of
the page.

Calling a method to a program

hello,
I have a requirement that I am working on, I need to create a program that will have vendor number and vendor bank account number on the selection screen.
Now what I need to do is I need to call a method from a class that will do some kind of validation, method name is 'validation'
My problem here is that method validation has only vendor bank account number as a parameter. Vendor number is defined as an attribute in the class, let's say z_vendor, and in the method we are using Z_vendor as a vendor number.
Can you please tell me how can I set the value of the attribute to the one that the user will enter using a FM and then how to call the method validation in to my program.
I can not make any change the way class has been declared.
The attribute z_vendor is defined as follows:
1. Level - Instance Attribute
2. Visibility - Public
I am very new to OOPS.. so any help will be really appreciated.

Hi Rahul,
You can do like this:
data:lr_object type ref to CLASS (NAME of your class)
create object lr.
1.lr_object->z_vendor = vendor no.
2. call method lr_object->method name (in Importing parameter pass the vendor bank account no.
And then in the method your vendor no and bank account will be passed.
Thanks

LVOOP "call parent method" doesn't work when used in sibling VI

It seems to me that the "call parent method" doesn't work properly according to the description given in the LabVIEW help.
I have two basic OOP functions I am doing examples for. I can get one to work easily and the other one is impossible.
Background
There are 3 basic situations in which you could use the "call parent method"
You are calling the parent VI (or method) of a child VI from within the child VI
You are calling the parent VI (or method) of a child VI from within a sibling VI
You are calling the parent VI (or method) of a child VI from a different class/object.
From the LabVIEW help system for "call parent method":
Calls the nearest ancestor implementation of a class method. You can use the Call Parent Method node only on the block diagram of a member VI that belongs to a class that inherits member VIs from an ancestor class. The child member VI must be a dynamic dispatching member VI and have the same name as the ancestor member VI
From my reading of that it means situation 3 is not supported but 1 & 2 should be.
Unfortunately only Situation 1 works in LabVIEW 2012.
Here is what I want
And this is what I actually get
What this means is that I can perform a classic "Extend Method" where a child VI will use the parent's implementation to augment it's functions BUT I cannot perform a "Revert Method" where I call the parent method's implementation rather than the one that belongs to the object.
If you want a picture
Any time I try and make operation2 the VI with the "call parent method" it shows up for about 1/2 sec and then turns into operation.
So there are only 3 possibilities I can see
Bug
Neither situation 2 or 3 are intended to work (see above) and the help is misleading
I just don't know what I am doing (and I am willing to accept this if someone can explain it to me)
The downside is that if situation 2 above doesn't work it does make the "call parent node" much less usefull AND it's usage/application just doesn't make sense. You cannot just drop the "call parent node" on a diagram, it only works if you have an existing VI and you perform a replace. If you can only perform situation 1 (see above) then you should just drop the "call parent node" and it picks up the correct VI as there is only 1 option. Basically if situation 2 is not intended to work then the way you apply "call parent method" doesn't make sense.
Attachements:
For the really keen I have included 2 zip files
One is the "Revert Method labVIEW project" which is of course not working properly because it wants to "call parent method" on operation not operation2
The other zip file is all pictures with a PIN for both "Revert Method" and "Extend Method" so you can see the subtle but important differences and pictrures of the relavant block diagrams including what NI suggested to me as the original fix for this problem but wasn't (they were suggesting I implement Extend Method).
If you are wondering where I got the names, concepts and PIN diagrams from see:

Call parent node fault.zip ‏356 KB
Call parent node fault.zip ‏356 KB

Hi tst,
Thankyou for your reply. Can you have a look at my comments below on the points you make.
1) Have to disagree on that one. The help is unfortunately not clear. The part you quote in your reply only indicates that the VI you are applying "Call Parent Node" to must be dynamic dispatch. There is nowhere in the help it actually states that the call parent node applies to the VI of the block diagram it is placed into. Basically case 2 in my example fulfills all that the help file requires of it. The dynamic dispatch VI's operation are part of a class that inherits from a given ancestor. Operation 2 for Reverted behaviour is a child VI that is dynamic dispatch and has the same name as the ancestor VI (operation2). The help is missing one important piece of information and should be corrected.
2) True it does work this way. I was trying to build case 2 and had not yet built my ancestor DD for operation so the function dropped but wasn't associated with any VI. I was able to do this via a replace (obviously once the ancestor Vi was built) so this one is just bad operator
3) Keep in mind this is an example not my end goal. I have a child implementation because this is a case where I am trying to do a "reverse override" if you like.
3a) The point of the example is to override an objects method (operation2) with it's parent's method NOT it's own. The reason there is a child implementation with specific code is to prove that the parent method is called not the one that relates to the object (child's VI). If I start having to put case structures into the child VI I make the child VI have to determine which code to execute. The point of Revert method is to take this function out of the method that is doing the work. (Single Use Principal and encapsulation)
3b) The VI I am calling is a Dynamic Dispatch VI. That means if I drop the superclass's VI onto the child's block diagram it will become the child's implementation. Basically I can't use Dynamic Dispatch in this case at all. It would have to be static. That then means I have to put in additional logic unless there is some way to force a VI to use a particular version of a DD VI (which I can't seem to find).
Additional Background
One of the uses for "Revert Method" is in versioning.
I have a parent Version1 implementation of something and a child Version2. The child uses Version2 BUT if it fails the error trapping performs a call to Version1.
LabVIEW has the possibility of handling the scenario but only if both Case 1 and Case 2 work. It would actually be more useful if all 3 cases worked.
The advantage of the call parent method moving one up the tree means I don't have the track what my current object is and choose from a possible list, if, for example the hierarchy is maybe 5 levels deep. (so V4 calls V3 with a simple application of "call parent method" rather than doing additional plumbing with case structures that require care and feeding). Basically the sort of thing OOP is meant to help reduce. Anything that doesn't allow case 2 or 3 means you have to work around the limitation from a software design perspective.
If at the end of the day Case 2 and case 3 don't and won't ever work then the help file entry needs to be fixed.
All the best

How to call a method of an other view in the current view

Hi Guys,
I have 2 views in my Project: IPrivateValidateIncidentView and IPrivateRoadMapView. Now, a button in the IPrivateRoadMapView must call a method in the IPrivateValidateIncidentView. I cannot seem to figgure this out. I know that I will probably need to arrange things centrally in my Component COntroller somehow.
I have tried to see what methods I can Invoke on IPrivateValidateIncidentView from within the Controller to see if I can call the method OnActionDoneValidate() from there, but I can only seem to get a constant with this methods name: IPrivateValidateIncidentView.WD_EVENTHANDLER_ON_ACTION_DONE_VALIDATION;
Please help.
Christiaan

Hi,
You are correct, for your requirement you need to arrange the things centrally that is in Component Controller. As in above reply you need to Create your context in Component controller and then map them to both the views. So data will be available to both the views and finally you create a method in component controller and call that method from second view. So the data changes made in controller will be reflected on First View as they have context mapping.

I want to call a method from a class,which class is loaded dynamically.
Consider a classA and ClassB..
ClassB contains a method showvalue() which returns a String value.
I want to load a ClassB dynamically in ClassA,and call the method showvalue() and print the returned value of that method (showvalue).
How to do this?
Thanks

Since you found your way to Reflections and Reference Objects, I can only assume you know that reflection is the answer. Since the reflection tutorial on this site, and indeed, the many others on the web, can explain this a whole lot better and more consisely than can be done in a forum, I'll point you in that direction instead. As a starting point, and to show I'm not just fobbing you off, you're interested in the classes java.lang.Class, java.lang.reflect.Method, and the method Class.getMethod(String, Class[])

Calling a method from another class. Please Help!!

Here is my full program. Like I said in my last post. I am having trouble calling the baseMakesError1 method. This method is called in the subcallsbase1 method. Also, it would be of great help if you could look for any other errors with with my program. Thank you so much. I really appreciate it.

"ThomasR11.java [79:1] baseMakesError1(int) in ThomasR11.BaseRT cannot be applied to (ThomasR11.SubRT)"
...this error is telling out that you wrote baseMakesError1 to accept an "int" as an argument, and you are trying to pass it an instance of the ThomasR11.SubRT class. You either have to change baseMakesError1 to accept a SubRT as an argument, or change your call to pass an integer.

Operation not found error while calling AM methods from managed bean

Hi,
operation not found error while calling AM methods from managed bean.
written a method with two parameters in AM.
exposed the method in AM client interface
in the page bindings added the method in method action ..left empty in the value fields of the parameters.
calling the method from managed bean like below
String userNameVal = (String)userName.getValue();
String passwordVal = (String)password.getValue();
OperationBinding operationBinding =
ADFUtils.findOperation("verifyLogin");
operationBinding.getParamsMap().put("userName",userNameVal);
operationBinding.getParamsMap().put("password",passwordVal);
operationBinding.execute();
i am getting operation verifyLogin not found error.Please suggest me something to do.
Thanks
Satya

Hi vlsn,
Can you try with the below code
// in your backing bean
OperationBinding operation = bindings.getOperationBinding("verifyLogin");
//Put your both parameters here
operation.getParamsMap().put("parameter_name1", parameterValue1);
operation.getParamsMap().put("parameter_name2", parameterValue2);
operation.execute();
if (operation.getResult() != null) {
Boolean result = (Boolean) operation.getResult();
and share the result.
regards,
Rajan
