Call JavaScript-Method from Command in NW04s WebApplication

Hi,
I would like to use a command to call a JavaScipt-method. Is that possible?
I want to use a JavaScript generated from the following command as an ACTION_BEFORE_RENDERING-event.
<bi:TEMPLATE_PARAMETERS name="TEMPLATE_PARAMETERS" >
<bi:WEB_TEMPLATE_ACTIONS type="COMPOSITE" >
    <bi:ACTION_BEFORE_RENDERING type="COMPOSITE" >
      <bi:INSTRUCTION >
        <bi:SET_ITEM_PARAMETERS >
          <bi:cmd_item_parameters type="TEMPLATE_INCLUDE_ITEM" >
            <bi:TEMPLATE value="AIS_ANZEIGE_BETRIEB_NW_04" text="Stammdatenanzeige für Betrieb NW 04" />
          </bi:cmd_item_parameters>
          <bi:TARGET_ITEM_REF value="TEMPLATE_INCLUDE_ITEM_2" />
        </bi:SET_ITEM_PARAMETERS>
        <bi:SET_SELECTION_STATE_SIMPLE >
          <bi:TARGET_DATA_PROVIDER_REF_LIST type="ORDEREDLIST" >
            <bi:TARGET_DATA_PROVIDER_REF index="1" value="DP_2" />
          </bi:TARGET_DATA_PROVIDER_REF_LIST>
          <bi:CHARACTERISTIC value="AISIS003___F00069" text="" />
          <bi:RANGE_SELECTION_OPERATOR type="CHOICE" value="EQUAL_SELECTION" >
            <bi:EQUAL_SELECTION type="CHOICE" value="MEMBER_NAME" >
              <bi:MEMBER_NAME value="17630775" />
            </bi:EQUAL_SELECTION>
          </bi:RANGE_SELECTION_OPERATOR>
        </bi:SET_SELECTION_STATE_SIMPLE>
      </bi:INSTRUCTION>
    </bi:ACTION_BEFORE_RENDERING>
</bi:WEB_TEMPLATE_ACTIONS>
</bi:TEMPLATE_PARAMETERS>
I want to assign a new WebTemplate to an included WebTemplate and also assign a filter value to the new loaded DataProvider.
It works as a command, but I only want the new WebTemplate to be loaded, if the corresponding filter is set. Otherwise I want to load a different WebTemplate. I think I have to use JavaScript here, but I don't know how to link that to the ACTION_BEFORE_RENDERING-event.
Any ideas?
Thanks in advance.

Call C# method from javascript in WebView and retrieve the return value

The issue I am facing is the following :
I want to call a C# method from the javascript in my WebView and get the result of this call in my javascript.
In an WPF Desktop application, it would not be an issue because a WebBrowser
(the equivalent of a webView) has a property ObjectForScripting to which we can assign a C# object containg the methods we want to call from the javascript.
In an Windows Store Application, it is slightly different because the WebView
only contains an event ScriptNotify to which we can subscribe like in the example below :
void MainPage_Loaded(object sender, RoutedEventArgs e)
this.webView.ScriptNotify += webView_ScriptNotify;
When the event ScriptNotify is raised by calling window.external.notify(parameter), the method webView_ScriptNotify is called with the parameter sent by the javascript :
function CallCSharp() {
var returnValue;
window.external.notify(parameter);
return returnValue;
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = DoSomerthing(parameter);
The issue is that the javascript only raise the event and doesn't wait for a return value or even for the end of the execution of webView_ScriptNotify().
A solution to this issue would be call a javascript function from the webView_ScriptNotify() to store the return value in a variable in the javascript and retrieve it after.
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = ReturnResult();
await this.webView.InvokeScriptAsync("CSharpCallResult", new string[] { result });
var result;
function CallCSharp() {
window.external.notify(parameter);
return result;
function CSharpCallResult(parameter){
result = parameter;
However this does not work correctly because the call to the CSharpResult function from the C# happens after the javascript has finished to execute the CallCSharp function. Indeed the
window.external.notify does not wait for the C# to finish to execute.
Do you have any solution to solve this issue ? It is quite strange that in a Window Store App it is not possible to get the return value of a call to a C# method from the javascript whereas it is not an issue in a WPF application.

I am not very familiar with the completion pattern and I could not find many things about it on Google, what is the principle? Unfortunately your solution of splitting my JS function does not work in my case. In my example my CallCSharp
function is called by another function which provides the parameter and needs the return value to directly use it. This function which called
CallCSharp will always execute before an InvokeScriptAsync call a second function. Furthermore, the content of my WebView is used in a cross platforms context so actually my
CallCSharp function more look like the code below.
function CallCSharp() {
if (isAndroid()) {
//mechanism to call C# method from js in Android
//return the result of call to C# method
} else if (isWindowsStoreApp()) {
window.external.notify(parameter);
// should return the result of call to C# method
} else {
In android, the mechanism in the webView allows to return the value of the call to a C# method, in a WPF application also. But I can't figure why for a Windows Store App we don't have this possibility.

Calling methods from Command prompt

Hi,
OK this may seem crazy:).
Is it possible to call a method from the command prompt directly?.
For eg. I have a class UFOSeeker that has a static method getPosinSky.
Is it possible to just call this method directly form the cmd prompt?, something like this
[neo@zeno ~]java UFOSeeker.getPosinSky()
The . is wrong i know, but is there a way?.
Reason for asking this, just bored and wondering whether this would be possible?.
TIA,
kris

You could do it via another class and use reflection.
For example:
public class CallStaticMethod
    public static void main(String[] args)
        String className = args[0].substring(0, args[0].lastIndexOf('.'));
        String methodName = args[0].substring(args[0].lastIndexOf('.')+1, args[0].indexOf('('));
        try
            Class clazz = Class.forName(className);
            Method meth = clazz.getMethod(methodName, new Class[0]);
            meth.invoke(null, new Object[0]);
        catch ( Exception e )
            e.printStackTrace();
}You would then run:
java CallStaticMethod package.Class.method()
or in your example
java CallStaticMethod UFOSeeker.getPosinSky()
The code above does not do anything about passing in parameters or getting return types. If you are really bored you could add it in.

Call Java Method From JavaScript Function

hi everyone
i need a help in calling Java method from a javaScript method
ex:
function confirmAddRecord() {
cHours =document.getElementById('frmP:ChargeHours').value;
cSTime =document.getElementById('frmP:ChargeStartTime').value;
var answer = confirm("Are you sure you want to add Record?")
if (answer){
here i want to call the Java Method that is located in session bean that takes the upper params cHours & cSTime
else{
return false;
i know i can do it as an action button but it is required me to be in that way can any one help plz

That depends on the nature of your parameters. I guess you calculate the params on client and then want to submit them. In this case and if you don't want to use Ajax simple add some <input type="hidden"> elements (of course there correspondend components dependent of your framework) and store the params there. If the javascript isn't invoked by a button click, you can use a button nevertheless. Set visible="false" and call
document.getElementById('client_id_of_my_hidden_button').click();
(or maybe doClick() dependent on your framework).

How to call java method from workflow script?

Hi
I have a requirement of updating field value 'Document Status' based on review/approve of content from Workflow and hence need to update the version number. For that I need to call my java method from workflow during submit of review/approve condition. Please let me know how to call java method from workflow?
Is there any alternative better way to achive this requirement from workflow? Please suggest.
Thanks,
Sarang

OK. So, I think we can all conclude that you don't need to call any Java method, can't we? And, that wfUpdateMetadata is the command that will update your metadata.
Now, the question is what are its arguments. It has two - the first is the name of a custom metadata field to be updated (let's suppose that one field is called xMinorVersion, and the other xMajorVersion), the other is the new value, e.g. <$wfUpdateMetaData("xMinorVersion", "New value.")$>As for new value - do you insist on using strings? Since you want to increase the value, it would be more convenient to work with numbers. For instance, with integers you could go with <$wfUpdateMetaData("xMinorVersion", xMinorVersion + 1)$>With strings you will need to convert it to numbers and back to strings. Besides, what happens if you have more than 100 minor versions? (you mentioned you want to add 0.01, but that would finally increase the major version, wouldn't it?) So, I think these two numbers are independent (perhaps, with exception that increase on the major version set the minor version to .00).
If you want to present it, you can use profiles that will construct for you the representation 2.304 out of MajorVersion = 2, MinorVersion = 304
Solved?

Call jpf method from jsp

Is there anyway to call a method in Controller.jpf from a jsp page? I want to have my jsp page call a method from the jpf controller through an onChange event in the select tag. Otherwise I will have to write a large amount of javascript directly into my jsp page and really defeats the purpose of the MVC architecture. Any help is greatly appreciated. Thanks in advance.

The jsp might look something like this:
<netui:form action="DoThisOnChange">

<netui:select dataSource"" optionsDataSource="" onChange="this.form.submit()"/>
</netui:form>
And in JPF declare action named "DoThisOnChange" and write the logic to be done on event "onChange".

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

Calling a method from a super class

Hello, I'm trying to write a program that will call a method from a super class. This program is the test program, so should i include extends in the class declaration? Also, what code is needed for the call? Just to make things clear the program includes three different types of object classes and one abstract superclass and the test program which is what im having problems with. I try to use the test program to calculate somthing for each of them using the abstract method in the superclass, but its overridden for each of the three object classes. Now to call this function what syntax should I include? the function returns a double. Thanks.

Well, this sort of depends on how the methods are overridden.
public class SuperFoo {
public void foo() {
     //do something;
public void bar(){
     //do something
public class SubFoo extends SuperFoo {
   public void foo() {
      //do something different that overrides foo()
   public void baz() {
      bar(); //calls superclass method
      foo(); //calls method in this (sub) class
      super.foo(); //calls method in superclass
}However, if you have a superclass with an abstract method, then all the subclasses implement that same method with a relevant implementation. Since the parent method is abstract, you can't make a call to it (it contains no implementation, right?).

Need help calling a method from an immutable class

I'm having difficulties in calling a method from my class called Cabin to my main. Here's the code in my main              if(this is where i want my method hasKitchen() from my Cabin class)
                    System.out.println("There is a kitchen.");
               else
                    System.out.println("There is not a kitchen.");
               }and here's my method from my Cabin class:public boolean hasKitchen()
     return kitchen;
}

You should first have an instance of Cabin created by using
   Cabin c = ....
   if (c.hasKitchen()) {
     System.out.println("There is a kitchen.");
   } else {
        System.out.println("There is not a kitchen.");
   }

Calling a method from another file

This is pretty basic stuff but i can't seem to get it right. I am calling a method from another file. The other file IS located in the same folder BUT when i compile i get errors
"cannot find symbol" <===referring to limit and sieve i believe.
The method name is "sieve" the file name is "PrimeSieve2008" and "limit" is the variable in brackets in the real method.
     public static void main (String [] args) {
final int [] PRIMES;
int sieve = PrimeSieve2008.sieve(limit);
     PRIMES = sieve(getValidInt());
          for (int j = 0; j<PRIMES.length; j++) {
               System.out.println("Prime[" + j + "] = " + PRIMES[j]);
Is "int sieve = PrimeSieve2008.sieve(limit)" the wrong way to call a file?
Thanks a million,
Alex

I really am clueless here.in this one you are passing in limit.
in the other one you are getting limit from somewhere outside of main.
