Launch Webdynpro Callable Object in Mobile?

I am able to launch the normal Webdynpro Java application in Blackberry, but want to add it to GP Process using Callable Object, but no idea how can we get the URL for WD - Callable Object?
Is it possible to launch web dynpro Callable Object in Mobile like in blackberry? I am trying to write a program for Approval Process for my project. If any one have done this please let me know what URL we need to use to launch the WD-Java Callable Object in Mobile?
Please let me know if you have any suggestions.

How connect a webdynpro callable object to bapi?

hi all,
I need to make a webdynpro callable object that connects to a bapi, to extract and modify data. I understand that this is done through a CAF. How can I make the connection?
Thanks!

in webdynpro callable object you can use models to connect BAPI/RFC
Please read the following document

Can't add GP Component Interfaces to WebDynpro Callable Object

Hi, I've just installed the IDE for Composition Environment 7.1 SP3 and I'm following the tutorial to create a WebDynpro Callable Object for a Guided Procedures that I'm working for a demo. It seems that there is something wrong with my NWDS, 'cause once I add the the required DCs dependencies to my project for caf/eu/gp/api and caf/eu/gp/api/wd and mark them for Design time, I cant add the to any new component as implemented component interfaces 'cause the list for adding them is empty. I really don't understand why this is happening, 'cause that's the way the tutorial explains it to work. I've already try to reinstall the NWDS, without success. Has any of you face the same problem?
Thanks for you answer.

Hi,
You should not create Design Time dependency. It is not required.
Ensure only that you have created a Build Time dependency on the public of "caf/eu/gp/api and caf/eu/gp/api/wd".
After creation of dependency ensure that you have build WD DC.
Check if it works now ?

Unable to craete ABAP Webdynpro callable object

Hi all,
I am not able to create a callable object for a ABAP Webdynpro application.
The SAP system has been configured properly in Endpoint Aliases and the Test Connection is successfull.
The problem is that whenever I search any ABAP WebDynpro application it says "Application with this name not found". There are many ABAP Webdynpro applications on the SAP server and even if I search for * it gives me the same message.
Please help.
Thanks,
Vivek

Hi,
Is your EAR having gp/api in tis dependency. It should be added with dependency at runtime and deploy time. It should also have run time,deploy time dependencies towards your DC having the java class(Background object).
Hope it helps.

How to debug WebDynpro callable Objects?

Hi Colleagues,
how can i debug a webdnpro callable object? The NWDS debug wizard always would have an "application" to start a debug session.
Best regards,

Hi,
I haven´t tried with Callable objects, but with CAF applications. I followed the instructions on the following link and I could debug my applications:

Understandng the callable object within GP

Hi All,
I have basic question on callable objects in GP.
I would like to know how the Adobe form content gets persisted with in GP .
Example : We have 4 steps in a GP process , one requestor and two approvers. Each step is a webDynpro callable object.
Requestor fills a Adobe form and this request goes through two approvers and then to complete state.
Consider we have two fields in adobe form. For my understanding , we need to take care of the business logic within the webDynpro callable object which takes care of storing the two field data into a database(Maxdb or SQl).Is that correct ? Or GP will take care of storing the content also ?
2. Another scenario
Assume that the application context stored with in GP process
The system restarted/down after the requestor submits his request. In that case will that request gets lost or GP will take care of storing......???
Please correct me if my understanding is not correct.
Regards, Anil
Edited by: Anilkumar Vippagunta on Jun 18, 2008 1:46 AM

Hi Sumangala,
Thanks for your response.
Lets consider I have 2 webDynpro callable objects..One is for requestor another for approver.
Requestor filled the adobe form in callableobject1 and submitted the request.For some reason j2ee got restarted or went down.
When requestor submits his request , GP will send the notification to the approver.So a task will be added to approver inbox.
So GP will take care of storing the process related information but not the content within Adobe or webDynpro application ...Am I right ??
I am just trying to analyze the overall behaviour of GP in all aspects.
Thanks, Anil

Callable object with external backend

Hi everyone!
Is it possible to create a form (the callable object) in Guided Procedures which takes its data from an external database? For example, say I want to create a callable object in Guided Procedures which picks up user information from an MS Access database? If its possible, could anyone provide a hint as to what kind of callable object I need to declare and how I connect to the external database?
Any links to documents explaining such a scenario would also be of course welcome..
Thanks in advance,
Sameer

Sameer,
Its possible to fetch data from an external database.For instance, you could utilize a 'Webdynpro Callable Object' for the same.
You can very well establish a connection to the database using the regular JDBC connection APIs.
Once the connection is established you can read/write data from/to the database.
A simple example would be to write the connection code in the execute() method of your Callable Object.
Once you get the connection object, you can query the DB as you want.
For instance , you can have an Employee database with employee number as the primary key.
Now you can have this employee number as the 'input parameter' for the Webdynpro Callable object and rest of the details
like name, age , location you can have them as 'output parameters' for the CO.
Now when you execute this CO , it'll expect a 'valid' employee number as input,it'll go to the execute() method of the CO ,
make a DB connection,execute your 'select' query and give you the resultset.
You can loop thru the resultset to set your Output parameters.
A simple JDBC connection code for SQL Server DB looks like this:
public String makeDBConnection()
          try
               String strUserName = "db_user_name";
               String strPassword = "db_user_pwd";
               String strDB_IP = "db_ip";
               String strDB_Port = "db_port";
               String strDB_Inst= "db_instance";
               String strQuery="/your select query/";
               ResultSet resultSet = null;
               DriverManager.registerDriver(new com.microsoft.jdbc.sqlserver.SQLServerDriver());
               con = DriverManager.getConnection("jdbc:microsoft:sqlserver://" + strDB_IP + ":" + strDB_Port + ";DatabaseName="+strDB_Inst,strUserName,strPassword);
               stmtQuery = con.createStatement();
               resultSet = stmtQuery.executeQuery(strQuery);
          catch(SQLException e)
               e.printStackTrace();
Hope this helps.
Pls reward if helpful.

Reusability of web dynpro callable object

Hi,
I want to use same webdynpro callable object inside another callable object including some extra input and output parameter.
So that I dont have to write the same code again in another callable object.
is it possible?

Hi Ritu ,
Yes ofcourse we can use the same Callable object in another CO.
I dont think below mentioned is the better way to do .
while setting the input parameters and output parameters in the description method and execute method use if condition based on the status.
follow the same procedure in the description and execute method.
if (Status =="some value"){
set the Extra input parameters.
//below dont use else
normal input parameters for the callable object.
in the same way do it for the output parameters.
Note :here status can be anything.
for eg :
an employee open a leave form , here the status will be new.
when the employee submits the form to the higher authority, the status is "Submitted to higher Authority".
so the above scenario both the higher Authority can use same callable object. the difference is the higher authority CO have some additional fields such as "Remarks".
here based on the status we can use the same callable object.

Refresh Callable Object if changes are made to VC Start/End points

Looking for some guidance on how to refresh a callable object once I have already brought it into my application.
I have a VC application that I can use as a callable object during my GP process. During design time, I can select it and see the start and end points. I then can map those values and use them in the GP.
If I go back and change the VC application (make a change to the start or end point ... like a new variable or name change) how do I get my GP to recognize that there is a new version of the VC application? Currently I have had to delete the CO and rebuild it...Id rather the tool tell me the version has changed and that I need to remap/group my values.
Note that if I change anything between the start or end point in the VC application there is no problem, since all the GP cares about are those start/end points and how they relate to the rest of the process.

Hello Mike,
It´s a pitty but there is no way to "update" VC based callable objects in GP, (in webdynpro callable objects there is an "update" button that allows to do that) , but with Visual Composer Callable Objects the only way is to create a new one.
Regards,
Marco.

ABAP Webdynpro as callable object to connect MDM Server

Hi All
if we want create MDM workflows in portal thru GP then we need to create the callable object initially which will integrate the MDM system thru MDM Apis
suppose if we choose the option of taking the ABAP webdynpro as callable object then what is the development efforts/Steps to involve for creating the callable objects.
i hope that we can use the ABAP wendynpro thru MDM ABAP APIs where we can integrate MDM data in ABAP webdynpro application.
can you please list out what is the Aims from enduser level and development level.
Please more details on this??

Webdynpro Development Component Callable Object Escalation

Hi,
In gp sequential block workflow using webdynpro development component callable objects When the initiator intiates a workflow ,it is assigned to the first approver.Now if the approver does not take any action within 2 days i want to escalate the task to the second approver.How can i do this escalation?
There is a standard parameter call <b>due date</b>...in action.How can I set this value dynamically from my application..
During escalation , the next approver has to be taken by executing an rfc in the background
Please help....
Thanks,
Shamila

Hi,
You can define a CAF Core application service (implemented in the CAF Core layer) or a background CO (implemented by a J2EE class interface) which can call a RFC to get the next approver and return the next approver's user id as an output parameter. You can use dynamic user assignment in the next action (approval), by selecting the processor as "Filled From Context Parameter" (at the Roles tab in block level) and select the user id output parameter of the background CO/CAF app service CO.
You can get more details on different types of CO at the CAF Tutorial Center @SDN

WebDynpro Application as callable object in GP?

Hello,
I have created a WebDynpro application in NetWeaver Studio.I have to create a callable object of this application in GP.
This application is available in GP.I create a callable object of it, with an action, block process for this single object.(Since i cant test this callable object).
Once i generate url and acess it, it generates an error in browser saying:
"The page builder required to display this application UI inside the portal environment is not available".
Kindly help me solve this issue.
Thanks,
Sharath

Andre,
Thanks a lot for your how to guide.. it's really good!.. I've followed all your steps and I've created my WD DC. Everything works fine, the build is correctly made, but when I deploy the application the following error is getting throw:
