How to call a proxy written in ECC from Neteweaver Gateway

Hi Experts,
We have a scenario in our project where there is a proxy written in ECC which brings inventory data from POSDM system. We need to call this proxy and then send the data to SMP 3.0.
Can the experts guide me here on how to go about doing this?
Regards,
Saket.

Hi Krishna,
Thanks for your response. Let me explain in detail.
This is a enterprise service written in ECC to pull data from POSDM. Now we want to use this service to pull this same data from ECC in gateway to further send to mobile app.
Can you guide on the best way to achieve this?

How to call BRF Plus created in ECC from SAP PO 7.4 mapping

Dear All,
I'm working on a scenario where we are using BRF+ created in SAP ECC.
Since the business rules change frequently,we decided to used BRF+ instead of NWBRM where user/functional consultant can maintain rules easily.
The application is already created in ECC based on business requirement now I have to used this rules in interface to transfer data based on rules.
How can I call BRF+ rules through message mapping?
Can we used rfc lookup or soap lookup like we do in NWBPM in SAP PO 7.4.
Regards
Niraj

No, it is not an authorization issue.
As this interface has been generated in 4.7 using transaction BDBG, I am not able to change it in ECC 6.0.

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 = { } ;

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 Operating System commands / external programs from within APEX

Hi,
Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
Any pointers will be greatly appreciated.
Thanks & Regards,

Hi Guys,
I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
sqlplusw.exe user/password@database @script1.sql
sqlplusw.exe user/password@database @script2.sql
sqlplusw.exe user/password@database @script3.sql
sqlplusw.exe user/password@database @script4.sql
What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
Any help will be greatly appreciated.
Thanks & Regards,

How to call & pass values to custom page from seeded page table region

Hi All,
can anyone tell me how to call & pass values to custom page from seeded page table region(Attribute is not available in seeded page VO)
it is urgent. plssss
Regards,
purna

Hi,
Yes, we do this by extending controller, but you can also try this without extending controller.
1. Create Submit Button on TableRN using personalization.
2. Set "Destination URI" property to like below
OA.jsp?page=/<yourname>/oracle/apps/ak/employee/webui/EmpDetailsPG&employeeNumber={@EmployeeId}&employeeName={@EmployeeName}&retainAM=Y&addBreadCrumb=Y
Give your custom page path instead of EmpDetailsPG.
EmployeeId and EmployeeName are VO attributes(Table Region)
If you dont have desired attribute in VO, then write logic in your custom page controller to get required value using parameters passed from URL path.
In this case, only personalization will do our job. Hope it helps.
Thanks,
Venkat Y.

How to call another view controller's method from a view controller?

Hi,
Iam new to webdynpro . so pls clarify my doubt.
How to call another view controller's method from a view controller in the same Web Dynpro Component?
Thanks,
Krishna

Hi,
     The methods in a view are only accessible inside same view. you cannot call it outside the view or
     in any other view although its in same component.
     If you want to have a method in both views, then create the method in component controller and
     from there you can access the method any where in whole component.

You could deploy your EJB or Java under a web service into your OC4J, after that, you invoke a partnerlink from BPEL to the destination of wsdl will do. Also don't forget to add in your XSD schema as well.
