Calling Remote-Enabled JAVA Module from Web Dynpro Java

Anyone have a clue how I can call a Remote-Enabled JAVA Module in ECC from a Web Dynpro Java app? I'm on Portal 7.0. When I try and create an Adaptive RFC model in NWDS and put in the Function Module name (CFG_API_FIND_KNOWLEDGEBASES) or its Function group, that RFC is not returned for me to import. Can I not use this method to get at this function?
(I CAN call this function module and run it from the old SAP Business Connector software. That, however, does not help me get it into my Web Dynpro app.)

If anyone stumbles upon this thread, the long and short answer is you can't call a Remote-Enabled JAVA module in SAP from Web Dynpro Java.....using Adaptive RFC.
You can, however, if you create your own session and function call directly in Java code and give up on being able to use Adaptive RFC.

Hi
You can call RFC(remote enabled) from R/3 through Models in Webdynpro Java.You need to have JCO destinations.You connection properties of backend System

Calling Remote enabled Function module in java using RFC Destination

Hi
We are on Portal 7.3 ehp1 sp9.
Steps followed are :
RFC Destination called “SAP_RFC” has been created as below :
Configuration -> Destinations -> RFC Destinations
Connection and Transport:
Load balancing :Yes
Provided : SystemID / MS Server / MS Server Service / Logon Group / Gateway Host / Gateway Service
SNC : Inactive
Logon Data:
Authentication : Current User (Assertion Ticket)
Language : EN
Client : XXX
Repository Connection:
Destination Name : This Destination
Specific Data:
pooled Connection Mode : Yes
Max : 5
Size : 10
Max. wait time : 10,000
Ping Destination results : Successfully connected to System XXX as per user XXXXXXX.
JAVA Code as Follows:
JCoDestination destination = JCoDestinationManager.getDestination("SAP_RFC");
//destination.ping();
JCoRepository repository = destination.getRepository();
JCoFunction function = repository.getFunction("FM_NAME");
function.execute(destination);
Lines highlighted in RED color throwing an error as below :
{"ERROR":"Initialization of destination JCO_RFC failed: Incomplete logon data. on <SID> mshost <MS_HOST>/ com.sap.conn.jco.JCoException: (103) JCO_ERROR_LOGON_FAILURE: Incomplete logon data. on SID mshost MS_HOST"}
And found that no COOKIE with the name “SAP_SESSIONID_<system>_<client>” was not found, I am afraid that “Assertion Ticket” was not created in above scenario.
To confirm SSO configuration working, i have followed below steps:
1) Created System Object pointing to R/3 and tests were successful for authentication type "SSOLOGONTICKET / ASSERTIONTICKET"
It's J2EE application, no references or any other additional configuration been made part from above.
Any help ?
Thanks

Calling a new Browser Window from Web Dynpro Application - Empty Context

Hello,
I want to open a view in a new browser window, and followed the same way which is described in this thread:
Open view in new browser window
My first try was creating two applications, which refer to the same Component Controller. The opening of a new browser window is triggered by an action, which is called in the other application. As both applications have the same Component Controller, I thought, the context content has to be the same, but actually the context attributes are empty after opening of the new window.
In my second try I created two applications with two different Component Controllers, mapped via embedded Interface Controller. The effect is the same - I have no context content in the view.
Please, can anybody help me?
Thank you in advance.
Ilona Seifert

I done something like this:
[code]
try {
strURL =
     WDURLGenerator.getApplicationURL(
                    "$<b>PROJECT_PATH</b>$/$<b>PROJECT_NAME</b>$",
                                        "$<b>APPLIC_NAME</b>$");
} catch (WDURLException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
strURL += "?par1=";
strURL += var1;
strURL += "&par2=";
strURL += var2;
strURL += "&par3=";
strURL += var3;
[/code]
and after i retrieve them:
[code]
Var1Value= WDWebContextAdapter.getWebContextAdapter().getRequestParameter("var1");
[/code]

Error on calling a BDC from web dynpro while it runs fine through FM.

I have created a function module for calling transaction ima2n using a BDC. This function module runs as intended, if function module is executed using SE37. if I call the same function module from ABAP dynpro view, on some event. I get the below error. I have debugged the function module but it runs fine. If i debug function module and run the BDC in mode "A" then i can see that BDC is performing the intended actions. This is a strange behaviour.. Please help.

Hi,
as BDC is calling screens and in Webdynpro ABAP you cannot use SAP GUI sceeen, you are getting short dump.

Calling Batch input from Web Dynpro - any alternatives for table updates?

Hi!
I am asked to create a screen in Web Dynpro for the GJ30 transaction (JV Cutback mapping of WBS' elements). I created a remote enabled function module which call batch input for GJ30 . Testing the Function modules direclty goes fine, but not calling the function module from WD. then I get the same error message as when I once tried to call SAP GUI from Web Dynpro ( Call transaction /submit program).
My next step is to try to create a batch input session (instead of call transaction) and run it using rsbdcsub, and then check the result of the run. But maybe this will fail of the same reason as well, and I suppose this will make the user waiting longer for the response .
I read somewhere that Web Dynpro does not support batch Input. But what can you do when there are no standard BAPI's for the update you want to do in SAP ? We are not supposed to do direct table updates.
Anyone who have struggled with the same issues and found a solution??
regards, Tine

Remote-Enabled JAVA Module

Hi,
There are certain function modules in CRM 5.0 which has attribute as 'Remote-Enabled Function Module'. An example of it is 'CFG_API_GET_KNOWLEDGEBASE'. Kindly let me know how to test them and use them.
Thanks in advance.

Hi Pravesh,
The purpose of RFC FMs are that you can use them remotly here you can call those FM from your Java Code. Also if you just want to test then execute the FM inside CRM only and test it.

Moving from Web Dynpro Java timesheet to Web Dynpro ABAP timesheet

Hi
We are in the process of moving from Web Dynpro Java ESS timesheet to Web Dynpro ABAP ESS timesheet. When using Web Dynpro Java ESS timesheet it is possible to enter time using a daily or weekly view.
When using the Web Dynpro version and ensuring the period type is set to weekly view for the data entry profile it is only possible to enter time on the weekly view, the tab for the daily view is no longer available.
Still using the Web Dynpro version and changing the period type to daily view I can enter time using the daily view and the weekly tab also becomes available, but the weekly tab is read only.
Do you know if it is possible to make daily and weekly timesheet entry for one data entry profile.
Thanks
Mark

Yes you can have only one view ie weekly or daily as per your CATS profile in CAC1.
but of course you can select multiple profiles
Configuration
The application configuration HRESS_AC_CATS_1 is provided by default and allows you to provide default values for the application parameters. It also allows you to specify the layout and appearance of the application.
The following application parameters are provided:
HIDE_CLOCK_TIMES_IN_WEEKLY
Hides the clock times in the weekly view.
MULTIPLE_PROFILE
Enables the selection of multiple data entry profiles from the dropdown list

Call a user defined method in web dynpro from interactive forms

Hi All,
how to call a user defined method in web dynpro java, when a selecting value from drop down list which is in interactive forms by adobe
thanks.
Edited by: venkat99 on May 24, 2010 4:52 PM

Well, you can use F4 help, of course, check here: http://help.sap.com/saphelp_nw70ehp1/helpdata/en/48/a1900622ec062be10000000a42189d/frameset.htm
You need to select the value first and then use the submit button, which is mapped to the WD action submit (you have to set this up in WD designer!!). To use the submit button for more actions, you need to use something like a hidden field, where the value is set according to the action you want to do with your submit button. The submit sends this value back to WD, where you can switch the program code according to the value.

Calling a remote enabled function module which does not exist in caller sys

Hi,
I have a a system ABC from which I am trying call a rfc enabled fm(Test) present in system XYZ.
The fm(Test) does not exist in the system ABC so I am getting generation errors and dumps.
Is there a way for me to call these remote enabled function modules which does not exist in the caller system without the obvious errors etc.
Is there any special way.
Thanks

Hi,
please check this sample:
REPORT zcallfm                                 .
DATA: xv_return TYPE sysubrc.
CALL FUNCTION 'DOESNOTEXIST'
DESTINATION   'NOWHERE'
EXPORTING     caller                = sy-sysid
IMPORTING     return                = xv_return
EXCEPTIONS    system_failure        = 1
              communication_failure = 2
              OTHERS                = 4.
It shouldn't throw any generation errors in your system!

Authorization error calling a XI web service from Web Dynpro

Hi all,
I'm trying to communicate to XI from a Web Dynpro application but I get an Unauthorization error (401).
I've generated a WSDL in XI and import it to web dynpro as a new Model. But when a I call the web service, the exception "Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized." appears.
I don't know how to pass the right user and password from Web Dynpro, I've tried the web service from SOAP client tools and it works fine.
I'll apreciate any help.
Regards,
Diego.

Hola mi nombre es Luis,
Creyendo que eres español te escribo en tal idioma.
He visto que a ti también te devolvía un error de autentificación 401, y que lo subsanaste, pero a mi con la solución que te dieron no me vale, ya que implemento el código que te ofrecieron para arreglarlo y ahora me da un fallo de "Server Error" poniendo en usuario y password, los correspondientes a XI.
+Request_MI_outTurnoverDetailsDisplay_MI_outTurnoverDetailsDisplay req=new Request_MI_outTurnoverDetailsDisplay_MI_outTurnoverDetailsDisplay();

req._setUser("username");

No sé si es que ese usuario y contraseña son otros distintos.
Si pudieras ayudarme, te lo agradecería.

Calling a Report Program from Web Dynpro

Hi all,
I have a requirement, where i have to call a report program from web dynpro?. Wether its possible to call a report program in web dynpro?. Is we can call it, how this functionality has to be achived?

Hello,
Yes it is possible to call report using SUBMIT statement from one of the method defined in COMPONENTCONTROLLER's method tab.
Once you define the method with SUBMIT statement then call that method with proper event.
Rest configuration will remain same for ABAP webdynpro.
Hope this helps.
Thanks,

CE 7.1 - How to call CAF services from Web Dynpro

Hi,
whats the suggested way to call caf services from web dynpro?
Of course I can use the Web Service model. But can I call caf directly?
I read something about caf web dynpro model, but I cannot find it in nwds 7.1. On some older tutorial it was in context menu of caf project, but it seems to be removed.
best regards
tom

Hi ,
The standard way is to use the web service model.
You have to expose the the services as web service and then you can use the wsdl url in the Adaptive web service model option.
The above option will be available when you click the Model in the webdynpro application and the click create new model.
Hope it helps you.

HTTP form post from Web Dynpro Java Application without opening new window

Hi Experts,
We are trying to submit form data to an external URL from Web Dynpro Java application. We are achieving this with the following piece of code.
try
   strPrintContent="<html>"+
     "<head>"+
     "<script type=\"text/javascript\">"+
     "function myfunc () "+
     "{"+
     "var frm = document.getElementById(\"paymentForm\");"+
     "frm.submit();"+
     "}"+
     "</script>"+
     "</head>"+
     "<body onLoad=myfunc()>"+
     "<form id=paymentForm method=post action=\""+merchantURLPart+"\">"+
     "<INPUT type=hidden name=username value="+userName+">"+
     "<INPUT type=hidden name=pass value="+passWord+">"+
     "<INPUT type=hidden name=senderid value="+senderID+">"+
     "<INPUT type=hidden name=dest_mobileno value="+mobile+">"+
     "<INPUT type=hidden name=message value='"+msg+"'>"+
     "<INPUT type=hidden name=response value="+response+">"+
     "</form>"+
     "</body>"+
     "</html>";
IWDWebResource webResource = WDWebResource.getWebResource(strPrintContent.getBytes(),WDWebResourceType.HTML);
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(webResource.getAbsoluteURL(),"WBSEDCL");
window.show();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException("Error : "+e.toString(),false);
But it opens another window. We dont need that. We have to stay on the same window. Please suggest what can be done.

Hi,
You can create a HTML file with the request post parameters and the external URL something like this:
public java.lang.String GetRedirecturl( )
// External URL
String html = "<html><head></head><body onload=\"load()\"> " +
"<form id=\"form1\" action=\"https://www.abc.com/xyz.jsp\" method=\"POST\">" +
// Post Parameters
"<INPUT TYPE=\"HIDDEN\" NAME=\"Param1\"VALUE=\""+Param1Value+"\">"+
"<input name=\"sap-wd-resumeurl\" type=\"hidden\"/>" +
"</form> " +
"" +
"<script>" +
"function load(){" +
"var loc = window.location.search.substring(1);" +
"var queryString = loc.split(\"sap-wd-resumeurl=\");" +
"if(queryString.length > 0)" +
"{" +
"var resumeURL = queryString[1].split(\"&\");" +
"if(resumeURL.length >= 0)" +
"{" +
" document.forms['form1'].elements['sap-wd-resumeurl'].value= unescape(resumeURL[0])" +
"}" +
"}" +
"document.getElementById('form1').submit();" +
"}" +
"</script>" +
"</body> </html>";
String redirectUrl = "";
byte[] byteArrayHtmlData = null;
try {
byteArrayHtmlData = html.getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
wdComponentAPI.getMessageManager().reportException("Internal error occurred. Please try after some time",true);
IWDResource htmlResource = WDResourceFactory.createCachedResource(new ByteArrayInputStream(byteArrayHtmlData), "Redirect.html", WDWebResourceType.HTML, true);
redirectUrl = htmlResource.getUrl(WDFileDownloadBehaviour.AUTO.ordinal());
return redirectUrl;
Hope this will be helpful.

Anurag
