How to call a custom action class present in one DC from a different DC

Hi Experts,
I have to implement one email functionality in my project.This functionality works fine if I use the Standard EmailAction class present in com.sap.isa.cic.customer package,but we need to change the email IDs in some cases so,we need to create a custom class.But if I create a custom Action class in Another DC(shext) and try to call this class from the config file present in the other DC(From where the Standard class was called),I am getting no Action Instance found for the declared Action(This Happens when the class is not present ).
From the error I interpreted that the presence of the Custom Action class is not recognised by the The DC.
Please confirm If my understanding is correct.
I also tried adding a a new public part in shrext and tried adding the same in the used dc for the DC from where I am trying to call the class.But the activity fails and it gives me the error that the DCs are Broken.Do I need to build the DCs after adding a public part or a used DC?
Please answer If anybody has faced the same issue or has a solution to it.
Thanks

Hi All,
I was able to resolve this issue myself.
I had to include the DC crm/isa/lwc and the DC mail in the used DCs of SHREXT .
So,all the jars got included automatically and I was able to create a new custom class for the required functionality.
Its working fine now.

How to define a Custom Action in VC 6.0 ?

Hi all
I want to know how to define a custom action like for a check box UI Element, I want particular action to be performed when it is checked ? How can I achieve this in VC 6.0
Please feel free to ask me if my question is unclear ?
Regards
Kapil

Hi,
Try adding an expression element on your form.
Go to the Expression control properties and in the Expression attribute enter
IF(@Selected==true,"X"," ")
@Selected is the checkbox. For your function call input use the expression element and not the checkbox.
Hope this helps. Let me know if it works.
Thanks.

How to call a custom controller method from view

Hi,
I ve created a simple web service and consumed it in a model. Mapped the input & output parameters to custom controller context which in turn mapped to component controller's context which in turn to view's contexts.
How to call a custom controller method from view?
Please explain the syntax.
Regards,
Manoj.

Hi Patralekha,
Give some idea for the below scenario:
I ve created a simple web service and consumed it in a model. What I did was
1) for the input parameters, mapped the node from view->custom controller->model
2)for the output parameter, mapping from model->custom controller->view.
It works fine.
But I don't want to access model nodes directly, rather I want to set the input param in somewhere else (like custom controller) before calling the appropriate method, same for the response also.
Share me your thoughts.
Regards,
Manoj.

Urgent!! How to call a custom transaction or an ABAP program in BSP?

Urgent!! How to call a custom transaction or an ABAP program in BSP?
We are pretty new on BSP. Would be very appreciated if any expert here give us the detailed steps on how to build up the application to just call a custom transaction (e.g., t-code: ztest) or an ABAP program. Would we have to create a button or event handler to do that? And the detailed steps?
Thanks in advance and we will definately give you reward points!

hi Durairaj,
During the time to wait for your answer, we copied Bernd's code from your last link, but when activating it, get the 1st error msg:
Field "CLIENT" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement. "DATA" statement."DATA" statement. The error shows up here:
<td>
<htmlb:inputField id = "client"
value = "<%= client %>" />
</td>
Then we added Client to the page attribute and define it as type String, then get another error:
The field "EVENT" is unknown, but there is a field with the similar name "EVENT_ID"."EVENT_ID". This error shows up at the beginning in the Event Handler:
OnInputProcessing:
code
event handler for checking and processing user input and
for defining navigation
event handler for data retrieval
event = cl_htmlb_manager=>get_event( runtime->server->request ).
IF event->name = 'button' AND event->event_type = 'click'.
button_event ?= event.
How to resolve this unknown Event error, need to define in Page Attribute tab? but with what type?
Actually we only want to run an ABAP4 program in BSP, the code is complicated, could you show us an easy way of doing this in BSP?

Thanks for this. Alas, I do not have the source code used to generate the jar file, and I have no means of getting it. I imagine, therefore, that I will not be able to update the manifest file.The manifest file is just a simple text file.
You can get at it by unpacking/repacking the jar file with the jar utility (tar like syntax).
... I assume that classpath is rather like the unix path.It specifies a list of jar files and directories containing java class files (and more).
Is there anything that defines the classpath for each login session and, if so, how do I add to it?As the link I posted says;
you can set a CLASSPATH env.var.

How to call a custom jDialog

I am using NetBeans 5.5 and created a custom jDialog. I want to be
able to call the custom jDialog from another Form. The dialog I created
allows a user to set parameters for a template. The template saves
basic employee information to a text file for populating a time card.
When the template needs to be altered, the user would call the
template, which is the custom jDialog, to reset the template.
I thought I could just instantiate the custom jDialog class I created and
use a 'go()' method to bring up the templateChooser jDialog but
nothing seems to be working. Here is some sample code:
Here are sample code:
public class templateChooser extends javax.swing.JDialog{
    /** Creates new form templateChooser */
    public templateChooser() {
    }//end template Chooser()
    public void go(){
        initComponents();
        templateAttributesEnabled(false);
        jCmbxDutyDaysEnabled(false);
        formLoadData_onDialogOpen();
    }//end go
}//end of templateChooser
public class tcForm extends javax.swing.JFrame {
    public tcForm() {
        initComponents();
        //jf.setVisible(true);
    }//end constructor
    private void jMenuItem_OpenTemplateMouseClicked(java.awt.event.MouseEvent evt) {
// TODO add your handling code here:
        //call the template dialag box
        templateChooser tc = new templateChooser();
        tc.go();
    } // end jMenuItem
}//end class

OK...I figured it out!!!
For all that our out there using NetBeans5.5. When using the MenuItem and selecting mouseclick as an event will not cause the desired action to occur. You have to select Action -> ActionPerformed for that menuItem. My menu Item now "fires" the event for my custom dialog to appear. Go figure...I would have thought that the event mouseClicked would be fine...I guess not.

How do you invoke custom java classes???

Could someone post a detailed method of invoking custom java classes that works including what files go where, settings and the way it is invoked etc.
I have tried various ways from this forum and in the documentation without success. I am using IDM 8. I found these instructions regarding how you would do it if you were writing custom resource adaptors in the deployment tools guide:
To install a resource adapter youve customized:
1. Load the NewResourceAdapter.class file in the Identity Manager installation
directory under
idm/WEB-INF/classes/com/waveset/adapter/sample
(You might have to create this directory.)
2. Copy the .gif file to idm/applet/images.
This .gif file is the image that displays next to the resource name on the List
Resources page, and it should contain an image for your resource that is
18x18 pixels and 72 DPI in size.
3. Add the class to the resource.adapter property in
config/waveset.properties.
4. Stop and restart the application server. (For information about working with
application servers, see Identity Manager Installation.)
I tried the instructions here but placed my custom class in a folder entitled custom instead of /adapter/sample. Not sure about instruction 3 or whether it is relevent. Anyway nothings working.

Hi,
The way to add custom class is the same as you followed , put them in the WEB-INF/classes.
To use the custom adapter ,
Go To Resources - > Configure Types -> Add Custom Resource .
Type in the fully qualified class name of the custom adapter you added.and Save.
Now the new adapter you added should showup in the list of available adapters when you try to
configure a new adapter.
(Make sure that the prototype XML of your custom adapter is correct so that it displays the correct name / type for the adapter in the adapter list.
Thanks,
Balu

How to call a custom method of same view?

Hello
I am developing a WDA on ABAP. I kept 3 LTA (Link To Action, kind of hyper link) on the initial_view, they perform the below functions (pls. note all the below 3 are on the initial_view ONLY),
1) LTA_1 -> Creates 'A' -> The linked EVENT for this LTA is CREATE_A
2) LTA_2 -> Creates 'B' -> The linked EVENT for this LTA is CREATE_B
3) LTA_3 -> Creates 'A' and 'B' -> The linked EVENT(onAction) for this LTA is CREATE_A_and_B, fine.
I wrote the ABAP code for creating the 'A' for LTA_1 in the associated Event Handler(method), same way i did for B
Now, for LTA_3 (Event is CREATE_A_and_B), i do not want to replicate the code from LTA_1 and LTA_2.
1) So, i guess, i just call the above )Event Handler) methods sequentially in CREATE_A_and_B's ABAP editor, am i right?
2) If so, pls. let me know how to call these methods, say, just for A, so that i will call for B on my own. Normally, we call as below
my_Class->my_method_name
3) If so, there is not-optional parameter as WDEVENT, just i need to pass blank for it?
Thank you

data: wdevent TYPE REF TO CL_WD_CUSTOM_EVENT.
wd_this->CREATE_A ( exporting wdevent = wdevent ).
wd_this->CREATE_B ( exporting wdevent = wdevent ).

How Upload File To Custom Action

We have requirement of uploading file from page to our action class where the file will be processed. We have created a action class using, GSF,
public class MyAction extends RenderPage
I want to send file from web page. In java we use apache commons file upload jar. This jar needs HTTPRequest object. However in my action I have ics variable which contains the request parameters.
Is there any way to do file upload using webcenter sites api? OR
Is there any way I can get the HTTPRequest object in action? OR
Any other thought?

Hi,
You need to use
create iXOS doc:
ARCHIV_CREATE_TABLE
delete iXOS doc:
First ARCHIV_GET_CONNECTIONS and then ALINK_DELETE or better CALL METHOD CL_ALINK_CONNECTION=>DELETE_BY_KEY
It's best to create an FM for this
view iXOS doc:
ARCHIV_GET_CONNECTIONS
All these FMs are available on your iXOS system. Check doc for detailed info

Hi,
I think you are working with Oracle EBS.
I don't think so that we can able to call the custom form on clicking button.
We can call the form from the standard form using both custom.pll and form personalization
In custom.pll using zoom function we can do this and in form personalization we can call the form by using form function, In both we call the form by creating a special menu in standard from and we used to call.
So please check further, and let me know if any i can help you any.
