Web Dynpro Import Web Service Model - not a valid NCName

Hi people,
We are having a problem while importing a WSDL as an Adaptive Web Service Model in Web Dynpro (CE 7.2 SP03).
The error is the following:
"Definition of qualified base /schema/element[5]/complexType/sequence/element[4] is not correct. The value of property is not a valid NCName."
We tried importing the same WSDL in other tools (XML Spy and SOAP UI). With these tools it could be read without errors and were able to successfully call the service.
The point is, why the import fails in Web Dynpro if the WSDL can be read in other tools ? Can we do something in WD to import the WSDL that is supposed to be "not correct" ?
Thanks in advance for your comments,
Daniel

Hi Pranav,
I was facing this issue sometime back and i figured out that the ABAP proxy namespace in my case had a '/' in it, because of which the internal name of the service had a '/' character too.
And this was unacceptable for the endpoint binding name in my case.
Since it is occuring for you in case of the service name (i figured it out from attribute definations/services@name), check if the proxy name have a special character like '/'.

Vivek

GP process action details in Web dynpro

Hi
I want to get the list of action and the actions details for a GP Process in web dynpro callable object.
Can anyone please help me.

Hi Ritu/Shanto,
I havenu2019t found a way to use GP API inside WebDynpro CO to get Action ID.
Using IGPExecutionContext you can get the Process ID and Task ID and using these IDs, you canu2019t reach Action ID (there arenu2019t Interface/Class/Method to get that by a reverse way).
What is your requirement? May be there are other ways to do that.

Access portal system details in Web Dynpro ???

Hello All,
I have a requirement such that in my Web Dynpro application, I need to figure out that the backend R/3 it is trying to connect to, is it a unicode or a non unicode system.
For this purpose, we maintain an additional alias name for the portal system starting with UNI_ if its a unicode box or NONUNI_ if its a non-unicode box.
Is there any other better way of storing this information.
<b>I need to know, how can we fetch all the alias names maintained for a sytem in portal using Web Dynpro APIs.</b>
Please help.
Thanks in advance,

Sharing a web dynpro project

I want to know few details about Web dynpro project
1.I have created a wd project and started working on it creating some views etc. Same is being done by another colegue of mine. for example he also had created same structure of the project started working on some views . What all ( files)should i copy from his system so that the views created by him is available to me.
How sharing of this works other than pvcs OR cvs
2. Is it possible for me to update my model using a modified wsdl?

Hi Sujesh,
For sharing the web dynpro projcts you need JDI(Java Develpment Infrastructure) installed in your server. In that you need DTR(Design Time Repository) service of JDI. For details on this try this link.

Cannot import DCs, necessary for Web Dynpro use in CAF GP

Hello!
I'm a newbie in SAP technologies. I want to develop a Web Dynpro (WD) application, which will be used as UI in CAF GP. The problem is that I cannot import necessary DCs for this!
As I understand, the following ones are necessary to develop a WD app for use in GP:
caf/eu/gp/api
caf/eu/gp/api/wd
com.sap.security.api.sda
(according to http://help.sap.com/saphelp_nw2004s/helpdata/en/b2/06ae42848bb211e10000000a155106/content.htm)
I acted as it is described in "Implementing a Web Dynpro CO which Implements the GP Interface" (https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59).
Actually, those DCs don't exist in my local configuration - so, as it is told in "Implementing a Web Dynpro CO which Implements the GP Interface", I tried to get the DCs from remote host (there's a server in Intranet with all stuff installed). In NetWeaver Dev Studio, in "Preferences -> Development Configuration Pool" I have written http://<local server>:50100. Actually, I don't know, what port should be used - I've written the one, which handles requests to SAP NetWeaver Portal. The response to "ping" button click is "HTTP response code: 403 (Forbidden)".
I tried to check the status of SLD, and went to http://<local server>:50100/sld. I have successfully logged in, but when I try to go to tab "Administration", I receive the message " 403 Forbidden. You are not authorized to view the requested resource."
Is there a problem with my roles & groups? Actually, I'm in group SAP_SLD_ADMINISTRATOR.
What is wrong?
How can I get the detailed information about the error (log files or something)?
Thanks in advance!

Barry, as I understand, I have no these roles, available for granting. Maybe, I've acted in a wrong way (the version of SAP NetWeaver is "Release 2004s".):
I logged in NetWeaver portal as administrator, went to section "User administration", selected my user, opened the tab "Assigned Groups" and searched for the groups you've written - I found no one

Import Data from Office Control (Web Dynpro for ABAP) into internal-Table

Hello,
I have a question concerning the Office Control UI-Eelement in Web Dynpro for ABAP:
How can I import spreadsheet data from the Office Control into a internal-table?
I have an Excel-sheet (without any data) which is shown initially in the Office Control. First the empty Excel-Sheet will be loaded and in the second step data from an alvxml-transformation will be loaded into the Excel-sheet with the method 'activatexmlsource'. This works so far. When I change the loaded data in the Office Control and save it it will be stored as XLS-File. The problem is that I'm not able to use existing Upload-FM because every function module I tried uses GUI-functions and WebDynpro has no GUI-functionality. I always get the error that data from clipboard cannot be imported.
So now the question is:
How can I import changed data from the Office control into a internal-table staying in Web Dynpro application?
Please give some advice, if you have some useful code or ideas.
Thanks

Hi,
Once you save to desktop again you have made some changes to that file, this file you want to upload it right.
Then in that case you need to use the FILEUPLOAD UI element right.

Import data from excel/csv file in web dynpro

Hi All,
I need to populate a WD table by first importing a excel/CSV file thru web dynpro screen and then reading thru the file.Am using FileUpload element from NW04s.
How can I read/import data from excel / csv file in web dynpro table context?
Any help is appreciated.
Thanks a lot

Hi,
Here are the basic steps needed to read data from excel spreadsheet using the Java Excel API(jExcel API).
jExcel API can read a spreadsheet from a file stored on the local file system or from some input stream, ideally the following should be the steps while reading:
Create a workbook from a file on the local file system, as illustrated in the following code fragment:
          import java.io.File;
          import java.util.Date;
          import jxl.*;
         Workbook workbook = Workbook.getWorkbook(new File("test.xls"));
On getting access to the worksheet, once can use the following code piece to access individual sheets. These are zero indexed - the first sheet being 0, the second sheet being 1, and so on. (You can also use the API to retrieve a sheet by name).
          Sheet sheet = workbook.getSheet(0);
After getting the sheet, you can retrieve the cell's contents as a string by using the convenience method getContents(). In the example code below, A1 is a text cell, B2 is numerical value and C2 is a date. The contents of these cells may be accessed as follows
Cell a1 = sheet.getCell(0,0);
Cell b2 = sheet.getCell(1,1);
Cell c2 = sheet.getCell(2,1);
String a1 = a1.getContents();
String b2 = b2.getContents();
String c2 = c2.getContents();
// perform operations on strings
However in case we need to access the cell's contents as the exact data type ie. as a numerical value or as a date, then the retrieved Cell must be cast to the correct type and the appropriate methods called. The code piece given below illustrates how JExcelApi may be used to retrieve a genuine java double and java.util.Date object from an Excel spreadsheet. For completeness the label is also cast to it's correct type. The code snippet also illustrates how to verify that cell is of the expected type - this can be useful when performing validations on the spreadsheet for presence of correct datatypes in the spreadsheet.
String a1 = null;
Double b2 = 0;
Date c2 = null;
                    Cell a1 = sheet.getCell(0,0);
                    Cell b2 = sheet.getCell(1,1);
                    Cell c2 = sheet.getCell(2,1);
                    if (a1.getType() == CellType.LABEL)
                       LabelCell lc = (LabelCell) a1;
                       stringa1 = lc.getString();
                     if (b2.getType() == CellType.NUMBER)
                       NumberCell nc = (NumberCell) b2;
                       numberb2 = nc.getValue();
                      if (c2.getType() == CellType.DATE)
                        DateCell dc = (DateCell) c2;
                        datec2 = dc.getDate();
                       // operate on dates and doubles
It is recommended to, use the close() method (as in the code piece below)   when you are done with processing all the cells.This frees up any allocated memory used when reading spreadsheets and is particularly important when reading large spreadsheets.
          // Finished - close the workbook and free up memory
          workbook.close();
The API class files are availble in the 'jxl.jar', which is available for download.
Regards
Raghu

Error while importing EJB model in Web dynpro: Unable to fetch the EJBs.

Hi,
We are getting the below error while importing ejb model to Web dynpro.
Error :
Unable to fetch the EJBs. Check if the selected Enterprise Application contain the EJBs.
I have created the public part-> It has a reference to EJB client and the enterprise application also has reference to the EJB project.The EJB is also added in dependency list.
But still we are getting this error. Could anyone please explain what can i do to solve this issue.
Best Regards,
Karthika

Hi Vishweshwara,
Thanks for your reply.
Please find the steps i followed while importing EJB model in webdynpro.
1. The Entity forwarding permission has been enabled.
2. public part reference has been created and through the reference entity option the ejbDC->Client public part is selected.
I followed all the steps mentioned in the document. But still i am getting that error. In EJB DC we have list of JPA entities and stateless session beans are exposed as a webservice(top-down manner).The enterprise application has a reference to the EJB DC.
I could be able to invoke the ejb service beans from ejb explorer and Webservice navigator.
I am able to insert,delete and modify the records from there.
Please let me know what could i do to resolve this error?
Best Regards,
Karthika

Attachement Details (GOS) in Web Dynpro (ABAP)

I posted this question in the Web Dynpro ABAP forum and got no response, so I'm moving it here:
We are developing a Web Dynpro application to display PO attachment details (PDF file etc).
In the corresponding R3 application, we use FMs ARCHIVE_GET_CONNECTIONS and ARCHIV_DISPLAY_LIST_2. They work perfectly.
The Web Dynpro application uses both FMs but one of them returns an error "Screen output without connection to user". This is returned from FM K_KKB_LIST_DISPLAY which is trying to popup a screen.
So we would like to know if we are going about this correctly or if we should be using different FMs.
Thanks for any insight you can provide.
