Dynamically creating Runtime users

Hi,
I am trying to create a workflow that would connect to a remote Unix Box with credentials & host details provided by user from New Scale as input parameters.
The problem that I am facing is how to dynamically create runtime users as well as Targets & associate the user with that Target.
Following inputs I will expect from New Scale - Host Name, user+pwd to connect to that Host.
Regards,
Abhi

As per Michael's reponse you need to access the WSDL for both Target and Runtime User.
Make sure you have enabled the TEO NBWS first(under file->server properties->web service in the master UI). Port 61527 for http, 61526 for HTTPS (both defaults)
For Unix connections I have done the exact thing you describe and I used the telnet target type as I find it easiest to work with.
I do a 3 step process... create runtime user, extract the GUID of that Runtime User from the output of the web services call, and then create the SSH connection and pass the GUID of the Runtime User into the SSH connection web service call.
Here is a screenshot of the create runtime user:
I extract the guid by using a match regular expression on ".*" and then doing a substring on that result.
Here is a screenshot fo the create SSH connection:

Is it possible to dynamically create a user variable at runtime from within a Widget?

I'm trying to develop a custom Interactive Widget. This widget will allow the user to take multiple attempts, and needs to store information about previously completed attempts so they can (hopefully) see their improvements over time.
I'm trying to figure out the best way to store the data about the previously completed attempts across multiple sessions in a LMS. It seems that the data stored in user variables is automatically stored/restored in suspend_data, which would be perfect. The issue is that I can't find a way to dynamically create a new user variable from within a Widget. It looks like I can only access user variables that the author has explicitly defined in the Captivate interface. I'd rather not have to force the author to define an empty User Variable that they'll never knowingly use, just to give the Widget a bucket to store its data.
Does anyone have any ideas for what might be the best way to accomplish this? I'd like to stick to standard, "approved" APIs as much as possible, but I'd be willing to bend some rules if necessary.
Thanks!

Ryan,
I assume you've asked this question here:
https://groups.google.com/forum/?fromgroups#!topic/elearning-technology-and-development/e5 vWZfJ6X8I
I asked a similar question here:
https://groups.google.com/forum/?fromgroups#!searchin/elearning-technology-and-development /leichliter/elearning-technology-and-development/Au88bu7LB5o/TC7xlo8iBpQJ
Philip gave you sound advice. You'll have to hijack/re-purpose the comments or the suspend data. I was successful in using SCORM comments in a Moodle system to store extra data I needed for a customer. It's not ideal, but it gets the job done. Here's a thread about that:
https://groups.google.com/forum/?fromgroups#!topic/elearning-technology-and-development/Yg YAMGfXQNw
If you use suspend data, you have to watch out for a few things:
1. It's base 64 encoded... so any data you append to what Captivate outputs will need to be in base 64 (that's a good practice anyway since the data has to be serialized).
2. On course re-entry, you'll need to capture the suspend data before it hits Cp to strip off / read your needed data. If the suspend data isn't in the format Cp expects, you'll get a nice white screen of death.
Ideally, it would be nice to be able to dynamically create user variables for purposes like this... and it's been requested in Cp 6.... we'll see if it gets added (not holding my breath). Until then, I'd use cmi.comments.

Creating Forte FieldWidgets Dynamically at Runtime

Hi Everyone,
Could someone please help me with the following problem I have when
creating Forte fieldwidgets dynamically at run-time. I am using Forte
ver. 3.0.G.2.
(-1-) I have a window class with an empty gridfield, <grfMain>, inside a
viewport. The idea is to populate the gridfield with DataField
fieldwidgets dynamically at runtime. Depending on some input criteria,
sometimes some of the DataFields need to map to IntegerNullables, some
to DoubleNullables and some to DateTimeNullables. (Please note that I
cannot use the Forte window workshop to create these fieldwidgets,
because different types of fieldwidgets will be needed at different
times, in different numbers, at run-time. ) Here is a sample of how I am
currently trying to achieve this:
dfDate : DataField = new;
dfDate.MaskType = MK_Template;
dfDate.DateTemplate = new( value='dd/mm/yyyy' );
dfDate.Row = 1;
dfDate.Column = 2;
dfDate.Parent = <grfMain>;
dfInt : DataField = new;
dfInt.MaskType = MK_INTEGER;
dfInt.Row = 2;
dfInt.Column = 2;
dfInt.Parent = <grfMain>;
dfReal : DataField = new;
dfReal.MaskType = MK_FLOAT;
dfReal.Row = 3;
dfReal.Column = 2;
dfReal.Parent = <grfMain>;
The code above is called after the window has been opened with the
Open() statement.
Looking at the code above, one obvious omission is that the "Mapped
Type" of the Datafields are not set up. In the Forte window workshop, an
interface is provided to set up the "Mapped Type" of the Datafield
widgets, but I'm not sure how to do that dynamically, and that is
basically my biggest problem here.
(-2-) If I now run the window class, the Datafield widgets get created,
and they all have the correct input maks, but no validation gets done
when one tabs away from the field. For example, Datafields with
MaskType=MK_INTEGER will gladly accept '--1--0++7', while Datafields
created in the window workshop (mapping to IntegerNullables) will do a
validation, and not allow one to tab out of the field before the extra
minus and plus signs are not removed.
I have the same problem with the Datafields which have
MaskType=MK_Template and DateTemplate='dd/mm/yyyy'. For the date, one
can enter something like '2*\**\****', and leave the field, while the
same type of datafield created in the window workshop (mapped to a
DateTimeNullable), will not allow you to leave the field before a valid
date has not been entered. To summarise, the input masks of my
dynamically created Datafields work fine, but no validation gets done
when the field looses the focus.
(-3-) As a test, I used the Forte debugger ("view"-"local variables") to
look at the differences between Datafields created dynamically, and
those created in the Forte window workshop. One very obvious difference
was that Datafield attribute "MapTypeName" was filled in for the window
workshop Datafields, but not for my dynamically created Datafields. The
problem is that Forte does not allow me to set this attribute
dynamically in my code. How else can I setup the Mapped Type
dynamically?
(-4-) In order to have a consistent look-and-feel throughout our Forte
project, we are making use of Domain classes for DATE and DECIMAL data
entry fields. My questions are:
(4.1) How must I go about creating Datafields dynamically that make use
of these Domain classes?
(4.2) Is it also a matter of setting up the "MapTypeName" attribute,
which I cannot seem to do?
(4.3) Is the mapping done differently for Domain classes?
(-5-) Another interesting thing to note for Datafields created in the
Forte Window Workshop, is that if the mapped type is IntegerNullable
with Input Mask = Integer, or DoubleNullable with Input Mask = Float,
then the Object that the Datafield widget maps to, must first be
instantiated before the Loose-Focus validations will start to work. For
example, if a Datafield widget called "dfTestInt" was created in the
Forte window workshop, which maps to an IntegerNullable, and Input Mask
= Integer, then the following line is needed before the window is
displayed: dfTestInt = new;
Without this line, one can enter something like '2---3+++7', and leave
the field.
This is not true for Datafields where the mapped type is
DateTimeNullable with say Input Mask Template='dd\mm\yyyy'. In this case
validations are done even thought the object being mapped to, has not
been instantiated yet. In other words you will never be able to enter
'2*/**/****', and leave the field for datafield created in the window
workshop. Maybe in this case the validation is being done by the
template itself?
Thanks in advance

what I mean is rendering JSF components on the fly, becuase some time you don't know things at design time. Lets say I am designing a page in creator that shows the total number of dependants that belongs to a primary inusrance member in text boxes. Of course we don't know in advance how many dependants we have for a specific member unless we go to databse and fetch all the data at runtime. Desiging some thing dynamic like that is very easy in CGI or ASP/JSP but JSF model seems very static due to it's design time feature.
So is it possible with JSF or not?

How do I receive notification of a change in the value of a dynamically created user interface object?

I need to know when the user has changed the value of a slider or a Boolean control that was dynamically created (not part of a dialog). Is there any way to do that without polling? I would have expected these controls to post a WM_NOTIFY message to the parent window in response to user events, but that does not seem to happen. Am I missing something?

Win32 controls do typically post WM_NOTIFY messages to the parent window for user events. The Measurement Studio UI controls are actually ActiveX controls, though, and events are handled differently for ActiveX controls.
If you have a resource ID for you control, the easiest way would be to create your control in the OnInitDialog method and handle the event the same way you would if you had added the control to the dialog at design-time:
Add a declaration for the event handler in the AFX_MSG block in the dialog header file.
Make sure the AFX_MSG block in the header file includes DECLARE_EVENTSINK_MAP()
Include an ON_EVENT entry for the event in the dialog source's BEGIN_EVENT_SINK_MAP block.
Include a DDX_Control entry
in the dialog source's AFX_DATA_MAP block.
Otherwise, you'll have to dynamically sink the event at runtime after you've created the control. Microsoft's Knowledge Base has a couple of good articles that demonstrate how to do this:

Runtime Error when creating SUS user

Hi All,

Hi
Which SUS Verson are you using ? Are you using SUS on the same system, where EBP is installed ?
You can create users and assign role to respective users in SUS for creating
Bids in Bidding starting form SUS. But you must replicate users from SUS to EBP.
Then only systems will identify each other while logging.

Nesting dynamically created movieclip at runtime?

Is it possible to nest a movieclip into another dynamically
created movieclip at runtime? The commented line of code works, but
I am trying to nest a movieclip after it is created into
another.

you can nest movieclips by using your commented code.
however, you cannot change a movieclip's parentage after it's
created.
you can "fake" a parentage change by creating a movieclip
with the parentage you want, copying its assets to the newly
created movieclip with the desired parentage and finally removing
the original movieclip.

Hi Chaitanya,
I think you are using a LDAP or SAP system to store users. The problem is when you are defining the datasource configuration file. This might be in *read only * mode.
You can check this by System Admin -> System Configuration -> UME Configuration ->Data Sources tab..
You check wether you data source config file is in read only mode or not. If this file is in read only mode you cannot create users from the front end
You need to create users from LDAP or SAP system what ever may be your back end.
Thanks,

You can use the UserEditor mbean createUser api to create users in the
default authenticator embedded
ldap server. You can also use jndi and ldap to create users. Or you can use
a LDAP SDK
product.
Search the newsgroup via google for some examples of the usereditor calls.
There is no easy way to create roles programatically.

Following is the text from Note for Custom Password Validation logic:
Customers who wish to use their own password validation logic may do
so by writing their own Java classes that implement the
oracle.apps.fnd.security.PasswordValidation Java interface. The
interface requires 3 methods to be implemented:
1) public boolean validate(String user, String password)
    - This method takes a username and password, and then returns true
or false, indicating whether the user's password is valid or invalid,
respectively.
2) public String getErrorStackMessageName()
    - This method returns the name of the message to display when the
user's password is deemed invalid (i.e., the validate() method returns
false).
3) public String getErrorStackApplicationName()
    - This method returns the application shortname for the
aforementioned error message.
After writing the Java class to perform customized password
validation, the customer must then set the value of the profile option
SIGNON_PASSWORD_CUSTOM to be the full name of the class. If, for
example, the name of the Java class is
oracle.apps.fnd.security.AppsPasswordValidation, then the value of the
SIGNON_PASSWORD_CUSTOM profile option must be
oracle.apps.fnd.security.AppsPasswordValidation. Note that AOL/J
will attempt to load this class dynamically. Hence it is necessary to
make the class accessible by AOL/J. This means that in Forms, the
class must first be loaded into the database using the loadjava
command.

Uploading data from excel file to a dynamically created internal table

Hi,
I have a requirement where i have to upload data from an excel file into a database table. I would be able to determine the structure of the table only at runtime based on the user input.. so i have created an internal table dynamically.
Could you please tell me if its possible to upload data from an excel file to the dynamically created internal table using any function modules?
I thought of doing this by declaring a generic internal table of one field and then uploading the *.csv file into it and then splitting it based on "," and then assigning it to the field symbol referencing the internal table.. but my file length exceeds 132 characters and i'm only able to get data of lenght 132 char's in my internal table ( generic one).
Could anyone please show me a way around this.

How to use process overriden public runtime user?

Hello,
While creating a unix/linux dynamic target, I am passing unix/linux hostname and username
manually.
I am using the dynamic target in 'Open Terminal Session' and overriding the default username
with Public authenticated username. Open terminal session is working fine and able to
ssh the linux host.
But 'Execute Terminal Commands' process is getting failed while using the same 'Open Terminal
Session' as target.
Even though i am passing the sam 'Open Terminal Session' as target; 'Execute Terminal Command' is using the default runtime user rather than using the process overriden public runtime user.
Please do the needfule for the same. Please let me know if I need to provide more information.
Thanks,
Prashant

Thanks for your reply Chris.
In Open Terminal Session we have Credentials tab, there we can override process runtime user with public key
but we dont have anything in execute terminal commands.
We have credentials tab in 'Execute Unix/linux scripts' also but we cant use Public Authenticated Runtime User.
I have attached snapshots for ref puposes.

Dynamic list of user(s) in Human task activity.

Hello Friends,
Warm Greetings!!!
Here is my query:-
Can we have dynamic list of user(s) in human task for the same role. Request will flow to executive but based on some parameter it needs to go to different executives and this would be checked at run time.
Please provide some clue or pointers for the same.
PK

===========
Assign tasks dynamically
You can assign users, groups, and application roles dynamically using XPath expressions. These expressions enable you to dynamically determine the task participants at runtime. For example, you may have a business requirement to create a dynamic list of task approvers specified in a payload variable. The XPath expression can resolve to zero or more XML nodes. Each node value can be either of the following:
Ref- http://docs.oracle.com/cd/E14571_01/integration.1111/e10224/bp_introhwf.htm
==============
Either You can put a Xpath expression on Owner (open Human task from composite and see the General tab ) or you can have rule based assignment for users .
Also in Xpath - Identity related functions can be found under - Identity Service Functions (from Functions drop down)

GP: Dynamically assignment of users

Hello,
i'm a newbie and i have the following question:
Can i dynamically assign the user of the next step in a guided procedure?
The initiator of my GP passes some data to a web service. The web service determines on the basis of the data the user of the next step in my GP. Is this possible? And how can i achieve this scenario?
Thanks in advance and best regard,
Matthias

Hi Matthias,
Unfortunately, the GP external service callable object only works for RFCs. You cannot use it for a Web Service.
Therefore, I would propose the following solution. You can import a Web Service as an external service in CAF (using the Composite Application Services perspective in the Developer Studio). Then you can use the external service from a CAF application service. The application service can already be exposed as a callable object, and you can take the user ID as an output. Then you can use the predefined callable object Assign Users to Process Role, and map the application service output to its input. To enable the assignment of the relevant user to the next action, you must consolidate the role created for the Assign Users action to the role created for the next action, and set the type of the new role to Runtime Defined. Then, at runtime the Assign Users object is executed in the background and the user is assigned to execute the next action.
You can find how-to guides describing how to import a Web Service in CAF and how to integrate it further into CAF in the https://www.sdn.sap.com/irj/sdn/developerareas/platform?rid=/webcontent/uuid/d8dbd703-0801-0010-c9bf-c04bc52f562f">caf [original link is broken] [original link is broken] (see tutorial N.81).

AutoScrolling of PanelLayout and setting Location of dynamically created controls

Hi, I have a question related to setting Location of dynamically created controls when my PanelLayout is scrolled down or up.
So basically I have wrote a code that lets me drag on control over other other and replace their's locations.
So I wanted to add possibility for user to dynamically add new controls (every new control is suppose to be 200px below previous) - everything is fine as long as I add them from upper section of my LayoutPanel (without scrolling) but when I try to add
them while I'm half dawn scrolled they are placed based on CURRENT left upper corner which is NOT a upper left corner of LayoutPanel therfore they are placed with wrong padding based on current scrolled position.
So my question is how can I avoid it and always add new controls based on LayoutPanel upper left corner? (I have already tried disabling AutoScroll while adding new control and enabling it back after adding - it works but I want to find PROPER way because
I'm sure there must be some kind of solution to it)
Thanks in advance.

Hi darekg11,
>> I have a question related to setting Location of dynamically created controls when my PanelLayout is scrolled down or up
I am wondering what the PanelLayout was, was it a “flowLayoutPanel” or “tableLayoutPanel”?
>> basically I have wrote a code that lets me drag on control over other other and replace their's locations
Did you mean you drag the control at runtime or at design time?
>> how can I avoid it and always add new controls based on LayoutPanel upper left corner
I could not reproduce your issue, and could you share us some key code or a simple demo to reproduce your issue?
I made a research about “scrolling panel”, and I think the link below might be useful to you:

Creating runtime data types

Hi
I need to dynamically create input fields with specified lengths(so that user cannot enter values beyond this length).
I do it like this.
IWDAttributeInfo attributeInfo =
    nodeName
    .getNodeInfo()
    .addAttribute(attributeName,
       "ddic:com.sap.dictionary.string");
IWDInpuField inputField =
   (IWDInpuField)viewHandle
                  .createElement
                  (IWDInputField.class,null);
int length = getLengthFromSomeMethod();
inputField.bindValue(attributeInfo);
inputField.setLength(length);
The input field added is of specified length, but still the user is able to enter value beyond this length. This i guess is due to the fact that attribute bound to the field is of type "ddic:com.sap.dictionary.string".
Can i create data types at runtime so that i might add attributes with this data type to a node at run time?
Is there any other way to solve this problem?

kaushal,
Try this:
attributeInfo.getModifiableSimpleType()
.setMaxLength(length);
"Length" of InputField declares (average) width of control in characters.
