Hi there,

 

i have some problems concerning my web dynpro abap configurations in the system. When i start an application the browser appears and displays the http 500 internal server error.  The required icf nodes are activated, as far as i know. the following properties are set:

 

hostname: aet

port: 8000

 

The generated url for the web dynpro application looks as follows:

 

http://aet.ls3001:8000/sap/bc/webdynpro/sap/zwdr_test?sap-language=EN

 

Maybe anybody of you out there has an idea for that situation.

 

Thanks for your afford and kind regards,

 

Albert

Hi all,

 

I'm having problems at connecting to the SLD from the Content Administrator. The only button I can use is to check the SLD connection, but this fails. In the SLD I'm also having problem,s with starting and stopping the SLD Server: "Failed to send start signal for complete cluster, SLD may still be stopped on other cluster nodes."

In the Logs I'm having some Errors:

This is how I have written for dynamically generating radiobuttons. I have some categories on left view, by selecting which, i will get corresponding questions and it generates 5 options, and user selects one and I need to pass it to back end. I am using IModifiableSimpleValueSet for filling the radiobuttons.

 

 

ISimpleTypeModifiable myType = wdThis.wdGetAPI().getContext().getModifiableTypeOf("Ans.option");

  IModifiableSimpleValueSet values = myType.getSVServices().getModifiableSimpleValueSet();

.

.

.

..

values.put(d,wdContext.nodeAns().getElementAt(d).getAttributeValue("option").toString());

 

Kindly help, if I am missing something.

 

 

 

 

  IWDRadioButtonGroupByKey radioKey = (IWDRadioButtonGroupByKey)view.createElement(IWDRadioButtonGroupByKey.class,           "ansRadio"+radio_count++);

  IWDMatrixHeadData matrixHead_radio = (IWDMatrixHeadData)radioKey.createLayoutData(IWDMatrixHeadData.class); 

  IWDAction radioAction = wdThis.wdCreateAction(IPrivateRightView.WDActionEventHandler.SELECT_ANS, radioKey.getId());

  wdComponentAPI.getMessageManager().reportSuccess("radio id"+radio_count);

  radioKey.bindSelectedKey("Ans.option");

  radioKey.mappingOfOnSelect().setString("optionID", radioKey.getSelectedKey());

  wdContext.currentContextElement().setSel_ans(wdContext.currentAnsElement().getOption());

  radioKey.setColCount(1);

Downloading table data into Excel sheet - Webdynpro Java

August 12, 2014, 5:56 am

Hi All,


We have developed a custom webdynpro application that executes an RFC and displays data in Table UI element. We have provided a button to download the data in excel sheet. When data is huge like, total number of rows filled up in the table are around 11,000 & columns are 32, and when user tries to download whole 11000 rows in excel sheet, the timeout occurs after 20 mins due to huge data. But when I apply filtering on the same table data and then try to download some 700 rows out of 11000 into excel, it took me around 3.36 mins.

 

If anyone encountered such scenario in past, please guide in this regard to speed-up the download to excel functionality or suggest any other alternative.



We are using 7.3 Portal and tableUtilities java class for export to excel functionality.


Thanks,

Amol.

Problem NWDS 7.3 - Adaptive WebService Model

March 16, 2015, 2:12 am
$

Hello everybody !

 

I would like to post one problem concerning the implement of a new WSDL file in my NWDS 7.3 and have your feeling or your tips if you had already encountered this kind of error.

 

What i have done :

 

- I have tried to import a WSDL file in my NWDS 7.3 in order to create a new Adaptive webService Model.

I have already tested this WSDL file in SOAP UI and webMethods with a proxy filled and the webService is working correctly.

 

Once i have created my new Model (Name : DBI1Model), i have linked my Model with my component controller (AsegmentCust) in which i want to call the webService. (see screenshot below) :

 

Picture1.JPG

 

You can see below in my Component controller context the model node linked with my Model :

 

Picture3.JPG

In order to call the webService, i need to fill the following fields : CodigoConsulta, Senha, Usuario and Valor1.

Normally, i should receive a XML string in the field Return.

 

In my controller, you can find below the code that i have implement in order to call the WS :

 

//Creation of the model

 

DBI1Model dbi1Model = new DBI1Model();

manager.reportWarning("Step1");

 

// Instanciation of the model node

 

Request_ConsultaOnLine input = new Request_ConsultaOnLine(dbi1Model);

input.setUsuario("TEST");

input.setSenha("TEST");

input.setValor1("08090788000267");

input.setCodigoConsulta(3);

 

manager.reportWarning("Step 2");

 

wdContext.nodeRequest_ConsultaOnLine().bind(input);

 

 

try{

    manager.reportWarning("Step 3");

 

    input.execute();

          

    manager.reportWarning("Step 4");

}

catch(Exception e){

          

    manager.reportException(e);

    manager.reportWarning("Fail");

          

}

 

 

When i execute the application and try to call this WS, i have the result below :

 

Step 1

Step 2

Step 3

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

Fail

 

 

Do you have an idea of the problem ?

 

Thanks,

Regards,

NIcolas
