How to execute a method used in Model

Hello Guys,
I want to know that how to retrieve the data from the Model used in my webdynpro project.
scenario
- I have created CAF appliation with Customer BO and generated this BO as a service called findAllCustomer. This service is tested and working.
- I have made a webdynpro project and created a Model by using WSDL link
- I have then referenced the Model nodes to the context of the component controller
- I have then generated a table by using template on view controller (list of customer)
question: how do I invoke the the method to fill the table of customers??
Regards,
NK

hello guys,
Thanks for the reply.
I have implemented the code what you guys have sent to me. I have implented this code on a Method of the component controller. Then I call that method on the button event of the view controller.
when i press the button, I got the error message.
Do you guys know where to set the authentication for this service?
com.sap.esi.esp.lib.mm.config.exceptions.TechnicalException: Failed to create Logical Port for Service Reference with id [CustomerBO_new_undefined_sg_1_BASIC]. Reason for the failure is that no one of the following Authentication Methods [None], [SAP Logon Ticket], or [SAML Assertion] is allowed in the related Communication Profile. Such an Authentication Method is needed as the Authenticaton Profile is [businessOrTechnicalUser] and no User Account is assigned, so the Authenticaton Profile is considered to be noAuthentication or businessUser. Related Communication Profile is [SAP_DEFAULT_PROFILE 1] and it allows Authentication Method(s) [User Name/Password (Basic), X.509 Client Certificate, SAP Logon Ticket, SAML Assertion, X.509 Certificate Doc.Auth., User Name/Password Doc.Auth.]

How to execute the method of a class loaded

Hi,
I have to execute the method of com.common.helper.EANCRatingHelper" + version
version may be 1,2, etc
if version = 1 the class is com.common.helper.EANCRatingHelper1;
Iam able to load the class using following code.But iam unable to execute the method of the above class
Can anybody help me how to execute the method of the class loaded.
Following is the code
String version = getHelperClassVersion(requestDate);
String helperClass = "com.redroller.common.carriers.eanc.helper.EANCRatingHelper" + version;
Class eancRatingHelper = Class.forName(helperClass);
eancRatingHelper.newInstance();
eancRatingHelper.saveRating(); This is not executing throwing an error no method.
Thanks

eancRatingHelper.newInstance();Ok, that creates an instance, but you just threw it away. You need to save the return of that.
Object helper = eancRatingHelper.newInstance();
eancRatingHelper.saveRating(); This is not executing throwing an error no method.Of course. eancRatingHelper is a Class object, not an instance of your EANCRatingHelper object. The "helper" object I created above is (though it is only of type "Object" right now) -- you have to cast it to the desired class, and then call the method on that.
Hopefully EANCRatingHelper1 and 2 share a common interface, or you're up the creek.

How to execute a method after page Load?

My question is very similar to what was discussed in following thread:
How to execute a method after page Load?
My requirement is that I want to run a method in backing bean of a page, immediately after the page gets loaded. In that method I want to invoke one of the method action included in the pagedef of this page, conditionally.
I tried using the approach given in the above thread, i.e to use <f:view afterPhase="#{backing_security.setPermPriv}">, but the problem is that our page is not using 'f:view' , so I explicitly added one f:view with afterPhase property set , but it is not working, page it self is not getting loaded, it is throwing the error:
Root cause of ServletException.
java.lang.IllegalStateException: <f:view> was not present on this page; tag [email protected]e8encountered without an <f:view> being processed.

Hi,
I assume that your view is a page fragment and here - indeed - the f:view tag cannot be used. If you use ADF then one option would be to use a custom RegionController on the binding layer to listen for the render phase to invoke the method. Another option would be to use a hidden field (output text set to display="false" and have this component value referencing a managed bean property. The managed bean property's getter method can now be used to invoke the method you want to run upon view rendering

How to execute a method on mouse move event on an Image

Hi All,
I want to execute a method on mouse move event or mouse click event to an image.
how can i achieve this?
TIA,
Vishal

I am not sure if commandImageLink or goImageLink solve your requirement.
But as a workaround you can use set of ClientListener and ServerListener with af:image to achieve what you need.
using then you can capture client event and convert that into server event which you can use to call a bean method.
Inside this bean you can call a web service or method binding.
My first link in previous post shows that very well....

How to execute a method from String object?

I have some methods in String objects, example:
String methodOne = "someMethod1";
String methodTwo = "someMethod2";
public void someMethod1() {
public void someMethod2() {
How can i execute that methods, when the method names i have only in String objects?

You can get the method directly from the name and parameter types if you want to avoid using the loop:public class Foo27 {
public static void main (String[] args) throws Exception{
    String methodOne = "someMethod1";
    String methodTwo = "someMethod2";
    Object foo = new Foo27();
    Method method1 = foo.getClass().getMethod(methodOne, new Class[]{});
    method1.invoke(foo, null);
    Method method2 = foo.getClass().getMethod(methodTwo, null);
    method2.invoke(foo, null);
public void someMethod1() {
    System.out.println("someMethod1");
public void someMethod2() {
    System.out.println("someMethod2");
}The parameter types are required as there could be more than one method with the same name.
For somereason when I tried to create a new Method object and invoke it, an exception was thrownThere isn't a public constructor for Method, so how did you create a new one?

hope this helps

How to execute SQL Script using windows powershell(using invoke-sqlcmd or any if)

OS : Windows server 2008
SQL Server : SQL Server 2012
Script: Test.sql (T-SQL) example : "select name from sys.databases"
Batch script: windows MyBatchscript.bat ( here connects to sql server using sqlcmd and output c:\Testput.txt)
(sqlcmd.exe -S DBserverName -U username -P p@ssword -i C:\test.sql -o "c:\Testoutput.txt) ---it working without any issues.....
This can execute if i double click MyBatchscript.bat file and can see the output in c:\testput.txt.
Powershell: Similarly, How can i do in powershell 2.0 or higher versions? can any one give full details with each step?
I found some of them online, but nowhere seen clear details or examples and it not executing through cmd line (or batch script).
example: invoke-sqlcmd -Servernameinstance Servername -inputfile "c:\test.sql" | out-File -filepath "c:\psOutput.txt" --(call this file name MyTest.ps1)
(The above script working if i run manually. I want to run automatic like double click (or schedule with 3rd party tool/scheduler ) in Batch file and see the output in C drive(c:\psOutput.txt))
Can anyone Powershell experts give/suggest full details/steps for this. How to proceed? Is there any configurations required to run automatic?
Thanks in advance.

Testeted the following code and it's working.....thanks all.

5.Connect to current scripts location cd C:\scripts (enter)
C:\scripts\dir (enter )
C:\scripts\MyTest.bat (enter)
Note: can able to see the output in "C:\scripts" location as file name "TestOutput.txt".
Option2: Otherway, import sqlps and execution
1.Save sql script as "C:\scripts\Test.sql" script in side Test.sql: select name from sys.databases
2.Save powershell script as "C:\scripts\mypowershell.ps1"
# import-module "sqlps" -DisableNameChecking #...Here it not required.
invoke-sqlcmd -Servername ServerName -inputFile "C:\scripts\Test.sql" | out-File -filepath "C:\scripts\TestOutput.txt"
3.Connect to current scripts location
cd C:\scripts (enter)

How to execute a report using a transaction code?

Hi team,
I am new in ABAP and I want to do a very simple report and then call this report using a transaction code.
Steps:
1) create the report (SE38)
   the report is: Z_DEMO
2) generate a transaction code for this report (SE93)
   note: the transaction code is ZDEMO
3) call the transaction generated on step 2
When I execute the report using SE38, everythig is ok and the records are inserted in my table zdemo2.
But when I call my transaction ZDEMO there is no insertion. Why?
The report ask for parameters and then fowards me to SAP's main menu.
Thanks,
Walter.
The report is:
REPORT Z_DEMO.
tables: zdemo2.
parameters:
        nombre like zdemo2-nombre,
        edad like zdemo2-edad.
data:
      begin of tabla occurs 0,
        nombre like zdemo2-nombre,
        edad like zdemo2-edad,
      end of tabla.
zdemo2-nombre = nombre.
zdemo2-edad = edad.
insert zdemo2.

Hi,
While creating the transaction for your program
1>Make sure u give the program name and screen number
2>Important thing is a option "GUI SUPPORT"
Check all the checkboxes or atleast SAPGUI for Windows to ensure that the Code runs in SAP GUI.
Thank you.

SEPA - How to control payment method used for SEPA during invoice entry?

Hi,
To implement SEPA Credit Transfers, a new payment method must be created.
But this payment method will coexist with other payment methods that can be used for EUR payments between non-SEPA countries...
Is there a way to control during invoice entry that the user is using the right payment method? Thus, if the payment is to be made between two SEPA countries, is there a way to control that the payment method used is well the new SEPA payment method? These pmts would fall in error if OSS note 1406227 has been implemented (it creates a table that controls the validity of pmt methods per country of destination) but obviously, we want to control this before the payment run F110...
Or is it only controllable via a user-exit?
Thanks a lot!

How to execute .sql file using ODI

Hi All,
I need to execute .sql file using ODI.
I tried @{path}{file} command in ODI procedure selecting oracle technology.but it is failing.
Do any one have any other idea to execute .sql file.
Thanks in advance

Ohk...I think you can try creating batch file(.bat) if its Windows & call that from ODIOSCommand.
The bat file should contain scripts which call .sql file using sqlplus & there you can use @{path}{file} format.
See if this helps.

User, I fail to understand what your header (of the question) has to do with the stack trace. You get a npe in your code
view.com.pof.admin.users.POFAdminUser.createPasswordHistory(...)
This is the point where I would start my investigation.
