Upload File Callable Object (GP)

Hello,
I want to create a process where a user:
1 - Fills in a form
2 - Uploads a file using the "Upload file" callable object
3 - Another user receives a workitem with the data from the form, and the file.
I know I can use attachments, but I want to have an explicit "Upload FIle" step. If I don't, people will forget to upload the file....
Problem is I can't seem to map the file, into the "Display Form" of step 3. Is it possible?

Hi,
For creating WD callable object you need to add following three DC in your WD DC project.
In the Web Dynpro Explorer of the Web Dynpro Perspective, expand the node DC MetaData -> DC Definition, and select Used DCs.
a.      To create a DC dependency, open the context menu and choose Add Used DC.
b.      Select Local Development -> SAP-EU -> caf/eu/gp/api/wd -> DC MetaData -> Public Parts -> GPWebDynproCO. For Dependency Type, select Build Time, Design Time, and Run Time. Choose weak from the dropdown list.
c.      Repeat the previous step to define a dependency to DCs SAP-EU-> caf/eu/gp/api (public part external) and SAP-JEE -> com.sap.security.api.sda (public part default).
You need to do one more thing like bellow.
Select your Web Dynpro project and open its context menu. Choose Properties.
1. Choose Web Dynpro References -> Library References.
2. Add a reference for library caf/eu/gp/api.
I think this will help you.
Thanks

Upload file in Web Dynpro and add to Workflow container as SOFM object

Hi!
I have a Web Dynpro for ABAP application that should send attachments of uploaded files to a workflow container. I have already managed to do this, and it works fine for TXT files, but when I try to attach a WORD (.DOC) file the file looks corrput when I open it from the SAP inbox.
When uploading files in Web Dynpro it is as an XSTRING. I have tried out the following alternatives regarding convertion of the XSTRING before it is inserted in the SOFM object:
1) Convert from XSTRING to STRING using codepage 4110.
Then it is split into a string table of 255 chars
2) Convert from XSTRING to STRING using codepage 4102
Then it is split into a string table of 255 chars
3) Convert from XSTRING to BINARY format
I use function module 'SWL_SOFM_CREATE_WITH_TABLE'
and then swf_create_object lr_sofm 'SOFM' ls_sofm_key.
before I call some macros to fill the container.
Anyone else who have tried to do this with success? I'm greatful for any help.
Regards, Tine

Hi,
I had the same problem in the last days and finally I got a quite simple solution:
I had a look at the FM SWL_SOFM_CREATE_WITH_TABLE an noticed that it calls another FM (SO_DOCUMENT_INSERT_API1) which has a tables parameter for HEX data and is actually able to create a SOFM object from HEX data.
I simply copied SWL_SOFM_CREATE_WITH_TABLE as a customer FM and applied a few changes to make it accept HEX data:
First I added a new table parameter in the interface which gets the HEX data from the calling application (uploaded data using BIN format):
OBJECT_CONTENT_HEX     LIKE     SOLIX
Here is the code of the FM (I marked all additional and changed lines with a comment):
function z_test_sofm_create_with_table .

The returned SOFM key I added to a container element. The element refers to event parameter of type OBJ_RECORD in my ABAP OO Class
Using this function I was able to raise an event by using Method cl_swf_evt_event=>raise
that invoked a workitem containing an Excel-File i had uploaded as binary file and passed to the FM z_test_sofm_create_with_table as document type 'XLS'.
In the woritem preview when clicking on the attachment the file was opened directly in Excel.
Actually the new lines for calculation the file size is not yet quite correct. At first glance it does not seem to cause any trouble, but I will stll check that. In FM SO_OBJECT_INSERT the size is again checked and calculated if initial, so leaving size initial might also be an option.
I hope this helps anyone having a similar issue.

Michael Gulitz

Interactive Form/File Approval Callable Object - %PDF- error

I have a GP which send out an Adobe Form via E-mail and waits for a response.
When the form is returned, I want to render the Adobe form from the UWL as part of the task.
I understand that the Process Control - Interactive Form/File Approval Callable object can be used for this.
However, when I try to open the task I get an error message saying the File does not start with %PDF-
Looking at the process context in the NWA, I do see the PDF binary content at that step.
Any ideas?
I have followed an example setup as shown on:
http://help.sap.com/saphelp_nw04s/helpdata/en/0a/964dfc764b4a428f4321f1ba33dbdd/frameset.htm
Thanks
Hennie Pieters

Thanks a lot Greg for the response.
If the output of an interactive form includes a structure called 'Interactive Form' with the attributes you mentioned, that will serve my purpose.
However, I am not seeing these fields any where in the default output of MY interactivev forms. Do I have to do something explicitly to see it in the output.
I would appreciate your prompt response.
Thanks

GP: Creation of process for uploading file with approval or a rejection

Problem: It is necessary to organise process of uploading files in KM repository with approval or a rejection.
I have created process with two callable objects.
1. File Input
2. Interactive Form/File Approval
Has grouped structure "File"
In Runtime, during object performance "Interactive Form/File Approval" there is an error:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: pdfSource of InteractiveForm UI element should be populated with pdf binary content in USE_PDF mode
It is one problem, the second problem consists in that how to organise a folder choice where the file will be loaded.

Hi Pustovoytov Stanislav ,
Check whether if the context attribute pdfsource is of binary type or any other type. It sbould be of binary type.
And about the second one you can organize the folder structure in the KM administration.
Thanks

Type in "Callable Object" gallery in CAF?

Hello,
I'm trying to follow the doc "Building the Job Application Process - SAP Composite Application Framework v1.1" to build a test process.
My environment is the NetWeaver Sneakpreview 2004s SPS4 on Windows 2003 Server.
sap.com/SAP-JEECOR 7.00 SP7 (1000.7.00.7.0.20060324070000) 20060703235737
sap.com/SAP-JEE 7.00 SP7 (1000.7.00.7.0.20060319012200) 20060703235756
I logged in ad Administrator, and verified that it also has the roles "GP Basic User" and "GP Business Expert".
After I clicked on "Create Callable Object", the next screen only shows 3 lines in the "Type" pane, which are 'Web Dynpro Form', 'Web Pages', and an expandable 'Data forms'.
I'm looking for "content package" and "Web dynpro component" types.
Am I missing something here? The install of the preview went without any errors (at least not on the installer console). I am able to create a Folder, create a new "content package", upload an HTML file into the package, and activate it.
Also, any references to such self guided study guides will be appreciated.
Ye

that was the easiest 10 points I ever received. thank you. so funny, sometimes you work your butts out and get no appreciation. in your case the question and answer was simple but I still get the maximum reward points. what a great return on investment.
Anyway, if your company is a SAP customer or partner, you should have or somebody in your organization should have the login id to service.sap.com. Otherwise go to SDN under the CAF Tutorial Center SAP Composite Application Framework - CAF Tutorial Center [original link is broken] where you should also get enough how-to guides. Enjoy you learning experience with GP!

If you have the ftp server at 8080 running (9iR2 only) the simples way is to upload it to the database through that server. You can then do whatever you want using the xdburitype() procedure.
Below is an excerpt of a script I use to register XML schema's (I've got some very long ones, about 150K). It should work with "any" file..
begin
     dbms_xmlschema.registerSchema (
          schemaURL => 'http://www.agralin.nl/WebQuery/ns/&1',
          schemaDoc => xdburitype('/age/&1..xsd'),
          local => TRUE,
          genTables => FALSE,
          genbean => FALSE,
          genTypes => TRUE,
          force => FALSE,
          owner => 'AGE'
end;

Is there a way to silently upload files?

Ok, so I've taken the plunge. I've started working on an AIR
app using Flash CS3. I'm putting together a little app that will
keep my online store updated with all the product updates from our
wholesaler. This includes parsing a csv file, downloading product
images from the wholesaler, updating the database, and then
uploading the images to our server.
The problem is that AIR does not seem to have the
functionality to silently upload files! Sure, I can use the
file.reference object to fire off the browse method, which then
opens the OS file browser window BUT I would really like the whole
thing to be hands off. In the past, I've written these types of
apps using Visual Studio but I haven't touched VS in two years.
Has anyone run across a way to silently upload or ftp files
in AIR?

Hey Oliver,
Thanks for your answer--the fact that it CAN be done has
gotten me a lot further on finding a solution. Here's what I have
so far. As it runs, I can see the progress and completion of the
upload but I'm still not getting it saved. I'm uploading it to a
ColdFusion processing page.
AS3 Code:
import flash.filesystem.*;
import flash.net.URLRequest;
//Silent File Upload (no browse window)
function imageUpload(imageName,uploadPage):void
trace('Starting Upload of ' + imageName + '\n');
var myFile:File =
File.applicationDirectory.resolvePath(imageName);
var request:URLRequest = new URLRequest(uploadPage);
request.method = URLRequestMethod.POST;
myFile.addEventListener(ProgressEvent.PROGRESS,progressHandler);
myFile.addEventListener(Event.COMPLETE,completeHandler);
myFile.upload(request,"theFile");
function progressHandler(event:ProgressEvent):void {
var file:FileReference = FileReference(event.target);
var pLoaded =
Math.ceil(event.bytesLoaded/event.bytesTotal*100);
trace(pLoaded + '% uploaded');
function completeHandler(event:Event):void
trace ('Upload complete.');
var uploadPage = "
http://www.aaronbday.com/upload_file.cfm";
imageUpload("angelic_cat.jpg",uploadPage);
Here's the CFM page:

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye

How to SCAN uploaded files for VIRUS in APEX

part 1:
Goal:
Do a virus scan of the uploaded file from APEX application prior to storing the file in custom tables.
The process:
Followed the document from www.developer.com:
Implementing an Anti-Virus File Scan in JEE Applications
By Vlad Kofman
Go to page: 1 2 3 Next
This article will discuss one of the ways to implement antivirus file scanning in Java, particular in the JEE applications. Viruses, Trojan Horses, and different malware and spyware are a real problem for current computer environments, and especially for the Windows operating system. If you are designing any application in Java that has a requirement to be able to upload external files, you have a potential security risk. By uploading, I mean any way to get the external file inside of the corporate firewall be it via HTTP protocol or any other means. It is quite common to have this type of requirement in an enterprise application and with Java being one of the most popular web development platforms, it is unfortunate that this type of gaping security risk is quite often overlooked.
Java's Development Kit (JDK) does not have any means to do the antivirus scan right out of the box. This is primarily because Java is a programming language, and does not have any virus scanning packages. Furthermore, anti-virus software is not Sun's area of expertise or business model. Developing this type of software (or Java package), and more importantly maintaining it, would be a huge task for Sun. Mainly because viruses are constantly evolving and keeping virus definitions up-to-date is a daunting task. Large companies such as McAffee, Symantec, or Zone Labs develop virus detecting and combating products and spend a lot of resources to maintain them.
Application Environment
To implement a virus file scan in Java, a third-party package needs to be used. For the purposes of this article, I will use Symantec Scan Engine (SSE) package, which comes with Java APIs. This package is an application that serves as a TCP/IP server and has a programming interface and enables Java applications to incorporate support for content scanning technologies. For this article, I used Symantec Scan Engine 5.1, which is available as a Unix or Windows install.
If you are using an anti-virus package from the different vendor, you will need to investigate what kind of APIs are available; however, the general approach should be similar. Also, note that my implementation can be used with JEE technology and any modern MVC framework such as Struts or Spring.
The architecture is as follows: A server machine needs to have SSE running at all times. This can be the same machine that hosts your Application Server, but in an enterprise environment this should be a different machine. The Default Port needs to be open through the firewall to allow communication with the scan engine. All JEE applications that need to do file scanning can talk to the SSE server machine through a default port. Also, multiple applications running on different application servers can re-use the same scanning server. For more information, you should refer to the Symantec Scan Engine (SSE) Installation Guide, available on the Symantec web site.
When an external file that needs to be scanned is sent to the SSE via its programming interface (Java APIs using the default port), before any other operation on the file is performed, the SSE returns a result code. For instance, a file is uploaded by an external user into the web email type application as an attachment; then, the SSE API is invoked by the application and the return code of pass or fail determines the outcome of the upload and whether that email can actually be sent. If you have an account on Yahoo mail, you probably have seen that Yahoo is using Norton Antivirus to scan all attachments, although no Java.
Click here for a larger image.
Figure 1: Screen shot from Yahoo
For details on the Scan Engine Server Installationm please see the Symantec Scan Engine (SSE) Implementation Guide from Symantec.
Here are some key things to remember about SSE:
•     Java 2 SE Runtime (JRE) 5.0 Update 6.0 or later must be installed on the server before the SSE installation is done.
•     After installation, verify that the Symantec Scan Engine daemon is running. At the Unix command prompt (if it's a Unix install), type the following command:
ps –ea | grep sym.
A list of processes similar to the following should appear:
o     5358 ? 0:00 symscan
o     5359 ? 0:00 symscan
If nothing is displayed the SSE process did not start.
If the SSE process did not start, type the following command to restart SSE:
/etc/init.d/symscan restart
•     Keeping the virus definition up to date is the most important task and if new updates are not installed, the whole scan becomes ineffective. Symantec automatically downloads the most current file definitions through LiveUpdate. Please make sure that firewall rules are in place to allow the host server to connect to the Symantec update service.
Project Setup
For the purposes of this article, I included a wrapper for the Symantec SSE APIs, av.jar, which has Symantec Java APIs and serves as a client to the SSE server and takes care of all communications with the server. Please refer to the download source section. The av.jar should be included in the Java CLASSPATH to work with the SSE. This jar contains a class called AVClient that takes care of actually sending the files to SSE as byte arrays and returning the result.
In my project setting, I added three variables to be accessed via the System.getProperty mechanism. For example:
AV_SERVER_HOST=192.168.1.150
AV_SERVER_PORT=1344
AV_SERVER_MODE=SCAN
The AV_SERVER_HOST is the host name or IP of the machine where Scan Engine is installed.
The AV_SERVER_PORT is the port where Scan Engine listens for incoming files.
The AV_SERVER_MODE is the scan mode which can be:
•     NOSCAN: No scanning will be done (any keyword that does not start with "SCAN" will result in ignoring the call to the Scan Engine and no files will be transferred for scanning).
•     SCAN: Files or the byte stream will be scanned, but the scan engine will not try to repair infections.
•     SCANREPAIR: Files will be scanned, the scan engine will try to repair infections, but nothing else will be done.
•     SCANREPAIRDELETE: Files will be scanned, the scan engine will try to repair infections, and irreparable files will be deleted.
Note: For the file stream (byte array) scanning, the only meaning full values are "SCAN" and "NOSCAN".
Using the SSE Scanning Java APIs
In any class where scan is required, call the scanning API provided in the AVClient object located in the av.jar. The AVClient object will establish connection to the Scan Engine server and has the following APIs:
Figure 2: The significant APIs for the communication with to the Scan Engine Server.
If scanning a file on the file system, in SCAN only mode, use the call that accepts filename only.
If scanning a file on the file system, with SCANREPAIR or SCANREPAIRDELETE, use the call that accepts input and output file names.
If scanning an in-memory file (byte array), use the call accepting byte array.
For example:
import com.av.*;
Initialize setup parameters:
static String avMode =
(System.getProperty("AV_SERVER_MODE") != null)
? (String) System.getProperty("AV_SERVER_MODE") : "NOSCAN";
static boolean scan = avMode.startsWith("SCAN");
static String avServer =
(String) System.getProperty("AV_SERVER_HOST");
static int avPort =
Integer.parseInt( (String) System.getProperty("AV_SERVER_PORT"));
Scan check example for an in-memory file byte array:
public void scanFile(byte[] fileBytes, String fileName)
throws IOException, Exception {
if (scan) {
AVClient avc = new AVClient(avServer, avPort, avMode);
if (avc.scanfile(fileName, fileBytes) == -1) {
throw new VirusException("WARNING: A virus was detected in
your attachment: " + fileName + "<br>Please scan
your system with the latest antivirus software with
updated virus definitions and try again.");
Note that if you are using this code inside of the MVC handler, you can throw a custom VirusException and check for it in the calling method and perform any necessary cleanup. I have included the class in the AV Jar as well.
For example:
catch (Exception ex) {
logger.error(ex);
if (ex instanceof VirusException) {
// do something here
else {
// there was some other error – handle it
For more details on the Scan Engine Client API, please see Symantec Scan Engine Software Developers Guide.

d)     my2.java – This is the class file I wrote to test that I am able to send a file and scan it and see the output in the JDEVELOPER. In this case the file is stored on the filesystem of the client machine. JDEVELOPER should be able to see the file.
NOTE:
“EICAR.com” is the test file downloaded from Symantec site to test a non malicious virus file. I n order to be able to test it like this, the Antivirus program running on your machine should be disabled, or else Antivirus will kick in and delete the file. In the first place you will not be able to download the test virus file either with anti virus running on the machine you are downloading to.
package com.av;
import java.io.*;
public class my2 {

int avPort = 1344;

e)     Then finally we have my1.JAVA, which takes the filename, and it’s contents in the bytes form and scans the file. The reason for this method is we are not storing the file on the filesystem, it is read into the memory and only if it is clean, it is put into the database or else notify the user.

Finally , you have the exceptions file,
e) package com.av;
public class VirusException
extends Exception {
public VirusException() {
super();
public VirusException(String text) {
super(text);
Once you have all these classes, you can use JDEVELOPER , to load these classes into the database: This is as follows:
Right click on the project, which has all these classes.
NEW -> deployment profiles -> load java and stored procedures.
When you are created deployment profile, you have to specify,
Loadjava options.
-f, -v (check the check boxes)
Under privileges:
-s – specify database schema these classes are loaded into
-s – create sysnonym check box
-g – grant to public or any specific users per your policy.
Under Resolver,
-r and –o (check the check boxes)
I accepted the default name storedproc1. Then you right click on the storedproc1.deploy, deploy to whichever database connection you created.
And then, In order to access this java class we need a pl/sql wrapper as follows:
create or replace package my1 is
function mycheck (pfilename in varchar2, psize in number)
return number;
end my1;
create or replace package body my1 is
     function mycheck (pfilename in varchar2, psize in number)
return number is
language java
     name 'com.av.my1.scanfile(java.lang.String, byte[]) return int';
     end my1;
And the code is invoked from sql plus as follows:
Select my1.mycheck(“filename”, “filebytes”) from dual;
One important catch in the above method is to send the filename and filecontents in bytes form. In order to send the file contents as filebytes, you will need another java class and load into the data base as described above.

Having main method helps you to run the file in JDEVELOPER or using JAVA.
DO not forget to load this class into the database.
And you create the pl/sql wrapper again as follows:
create or replace FUNCTION TOBY (pfilename in varchar2) RETURN VARCHAR2 iS
language java name
'ReadFileIntoByteArray.chk_file(java.lang.String) return byte[]';
And you call the function from sqlplus as follows:
Sql>Set serveroutput on size 20000;
Sql> call dbms_java.set_output(20000);
Sql> Select toby(“filename”) from dual; --
this file should be accessible, I mean you will not be able to send a file on your pc, from sql plus as sql/plus is running on your db server.
You will be able to see the output in sql plus:
If you are running it from the APEX:
When we use file browser widget from APEX, the file is stored in APEX_APPLICATION_FILES table. And we retrieve that into a variable and pass this variable to the function as follows:
DECLARE
scan_failed EXCEPTION;
x varchar2(400);
z number;
BEGIN
select filename into x from wwv_flow_files where name = :P1_FILE_NAME;
select my1.mycheck(x,toby(x)) into z from dual;
if z = 0 then
:P1_SUBJECT:= 'PASSED';

Problem with uploading files to SharePoint 2013 in cloud using web services. Keep getting error message and don't know why.

Hello everyone. I am having trouble writing a utility that uses SharePoint web services to upload a file and metatag it. It keeps throwing the following error message:
"The request failed with the error message: -- <html><head><title>Object moved</title></head><body> <h2>Object moved to <a href="/_forms/default.aspx?ReturnUrl=%2fsites%2fgk%2f_vti_bin%2fcopy.asmx">here</a>.</h2>
</body></html> --."
Not sure why. I pass the file that I am going to upload to the subroutine and it is suppose to upload it to the appropriate library. I have burned several days on this problem and I am not sure what is going on. I would appreciate anyone that can point me in
the right direction. Below is the subroutine that I have that is causing the problem. Obviously, I have stripped the name from the example.
Thanks
Mike

Hi,
If you want to upload a file to a library in SharePoint 2013 online, I suggest you use Client Object Model or REST API.
The code snippets in the two threads below will be helpful:

Uploading Files Using the REST API
http://blogs.msdn.com/b/uksharepoint/archive/2013/04/20/uploading-files-using-the-rest-api-and-client-side-techniques.aspx
You can handle the authentication with
SharePointOnlineCredentials object:

How can i Upload Files from my Flex 2.0 Application?

How can i do a Upload File funtionality with Flex 2.0? Do i
have to make the component? How is the code in Flex/ Action Script
to make this possible?. I'm new in this Flex world and it seems to
me very interesting to make RIA's Applications; in fact i'm making
a little Employees Application for my company and i'm trying this
technology and of course i need the functionality that i asking
for.
Regards.
Andres.

I haven't tried this, but I believe what you could do is
append
requestHeaders to the urlrequest object that you pass into
the file.upload()
method. The requestHeaders is an array of name/value pairs
that would be
included with your post. At least in theory, I believe that
shoudl work.
Good luck.

Problem in creating a callable object of type Business Logic

Hi SDN,
I am trying to create a callable object of type Business Logic in CE.
When I give all information and click Next, I get this error message.
Error while loading configuration dialog: Failed to create delegate for component com.sap.caf.eu.gp.ui.co.CExpConfig. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
Can anybody help me out with this problem.
Regards,
Sumangala

Hi.
I'm having the same problem as Senthil in NW2004s SP15 with my application service and methods not showing up in the Callable Object wizard for Composite Application Services after I choose the Endpoint. The only application name that shows up in the wizard is caf.tc, and the only service names that show up for it are LDDataAccessor, Metadata, and PropPermissionService.
My IDE is on one machine and the application server I deploy to is located on a different machine. My endpoint to the remote application server looks to be correctly configured. The Composite Application Service seems to be deployed properly as I'm able to see it and test that it works in the Web Services Navigator <http://remotehost:50000/wsnavigator/>
My deployed application service is a remote enabled service and is also web services enabled as well.
I'm not sure if this is relevant, but I noticed that the generated Java code does not create any remote EJB interfaces (only home and local interfaces were generated).
Something else I noticed is that when I proceed to the External Service Configuration -> Business Entities screen <http://remotehost:50000/webdynpro/dispatcher/sap.com/cafUIconfiguration>, I only see three business entities displayed, and the following error message is displayed: "Corrupt metadata has been detected. This may prevent some objects from being displayed. Check the server log for more details." I was unable to find anything in the instance log files. Is the error message indicative of the problem?
I am developing locally without a NetWeaver Development Infrastructure (NWDI) in place.
I'm wondering if the credentials specified in the endpoint require any special roles or privileges.
Senthil, do any of these additional descriptions apply to you as well?

Error building/creating WD Callable Object

Hello guys,
Pardon for reposting - I did post on the WD Java thread - and I think this is the more appropriate area to ask this question since its GP Callable Objects related.
While creating a WD Callable Object: I
I added Used DC: caf/eu/gp/api/wd to the WD DC. And added IGPWebdynproCO on the Implemented Interface. Afterwards, after building the DC, I got the following errors:
This compilation unit indirectly references the missing type com.sap.caf.eu.gp.co.api.IGPTechnicalDescription (typically some required class file is referencing a type outside the classpath)
The project was not built since its classpath is incomplete. Cannot find the class file for com.sap.caf.eu.gp.co.api.IGPTechnicalDescription. Fix the classpath then try rebuilding this project.
I tried repair and rebuild - and restared NWDS (and even restarted my PC).
Issue not resolved.
What else should I do?
Thanks!
Regards,
Jan

I solve this including DC from caf/eu/gp/api (external public part) as show
http://help.sap.com/saphelp_nw70/helpdata/en/43/e085d6421a4d9de10000000a155369/content.htm
Later the method getDescription throws error because not return anything, while I return null

Error testing Web Dynpro Callable Object (GP Interface)

With reference to thread:
Interactive form as Callable object error on testing the object.
FYI, I'm running NW04s, EP 7.0 SPS 13, JDK 1.4.2_14, Unix OS
Hi All,
I have created a Web Dynpro App with a Adobe Form as the frontend. I have included the caf/eu/gp/api as a DC and implemented the IGPWebDynproCO interface. Next I created a Web Dynpro Callable object in GP and ran a test and received the following error:
Result: Technical Exception
Details: Could not create web dynpro callable object component
Output Parameters
Callable object implementation did not return output parameters
Can anyone help me resolve this? Do I have to make a manual entry in the HOST file? If so, what is that entry? Are there alternatives?
Thanks
Kunal.

Hi,
For creating WD callable object you need to add following three DC in your WD DC project.
In the Web Dynpro Explorer of the Web Dynpro Perspective, expand the node DC MetaData -> DC Definition, and select Used DCs.
a.      To create a DC dependency, open the context menu and choose Add Used DC.
b.      Select Local Development -> SAP-EU -> caf/eu/gp/api/wd -> DC MetaData -> Public Parts -> GPWebDynproCO. For Dependency Type, select Build Time, Design Time, and Run Time. Choose weak from the dropdown list.
c.      Repeat the previous step to define a dependency to DCs SAP-EU-> caf/eu/gp/api (public part external) and SAP-JEE -> com.sap.security.api.sda (public part default).
You need to do one more thing like bellow.
Select your Web Dynpro project and open its context menu. Choose Properties.
1. Choose Web Dynpro References -> Library References.
2. Add a reference for library caf/eu/gp/api.
I think this will help you.
Thanks
Chandan
