Public Class in Web Dynpro

I have a little class
class OrgInfo
     public String McShort;
     public String Objid;
     public String Stext;
public OrgInfo(String mcShort, String objid, String stext)
     McShort = mcShort;
     Objid = objid;
     Stext = stext;
I'd like to call it from my views and component controller. How do I add the class?
Diane

Define the class as public and put it under src/packages/<your_package>.

Assistance class in Web dynpro ABAP

step 1: Create WEB DYNPRO component. Example: Zwd_assist_class_test.
             -save.
            -Active.
step 2: Assistance class on component(Zwd_assist_class_test) screenwriter assist class name Example:Asistance_class.
step3: Select the Assistance class name click on pop up new window .
step4:Assistance class window methods give method name
step5: Select parameters of the methods giving importing exporting table ,objects.
step6:Select Attributes button given the attribute name Example:ET_MAR.
For example methods READ_ONLY.
coding for method: select * from <db_table> into table <ET_tab> where matnr between im_matnr1 and im_matnr2.
I want using MARA,VBAK,VBAP tables data display in single table,creating two search fields .these are VBELN, MATNR
how to write READ_ONLY method ?

Hi Rajasekhar,
The exporting parameters which you have declared can take only one record as its declared as work area. Instead you need to identify the table type and use like
for MARA... MARA_TT
for VBAK... VBAK_T
for VBAP... VBAP_T
but, for your requirement, you need not required to pass mara, vbak, vbap table data, instead you need to put into final internal table ET_result.
I suggest you to create a table type ZTT_RESULT in SE11 which contains all your fields in the output.
Now, inside READ_DATA( ) method you can do as below ( just an example)
loop at lt_mara into ls_mara.
     move-corresponding ls_mara to ls_result.
     loop at lt_vbap into ls_vbap where matnr = ls_mara-vbeln.
           move-corresponding ls_vbap to ls_result.
          read table lt_vbak into ls_vbak with key vbeln = ls_vbap-vbeln.
          if sy-subrc is initial.
                    move-corresponding ls_vbak to ls_result.
          endif.
     endloop.
append ls_result to ET_RESULT.
endloop.
Hope this helps you.

Create utility class in Web Dynpro project

How do I create my own utility java class but keep it in the Web Dynpro project?
Do I have to create a separate java project and have the WebDynpro classes import it or can I keep it in the Web Dynrpo project?
I tried adding my own java class to the Web Dynpro project and when I did a rebuild all, the generator erased it.
Ideally, I would like to keep everything in the same project if possible as this utility class will only be used by the WebDynpro project.

Open Eclipse "Navigator" or "Package Explorer" view and put your class under folder src/packages.

To create a java class in Web dynpro

Hi,
I want to create a java class which can be used in multiple views. Where will i create it and how will i access it?
Can i create the class in Comp controller's imeplementation between "begin others"----
"end"?
Any help?
regards,
Sujesh

Hi,
If you create the class within the begin others"----
"end" section, this class will not be accessible by any other class.
You can create a class in
Project/src/packages/<namespace>/<your component>/<create a new subdirectory>/Test.java.
This will be accessible to all other classes. Just make sure the first line of your java file is the proper package declaration. So in this case the 1st line dhould be:
package <namespace>.<your component>.<subdirectory name>;

Add class to web dynpro

hi
i have a class ans i wont to add him to the program how & where i do that?
regards

This all depends on what the class is for. If this class is to do all of your business logic, it should be implemented as an assistance class, otherwise, you could simply add the object reference directly into the coding of the METHOD and call the methods of your class. Again, if this class contains all of your business logic, you would want to use it as an assistance class within your component.

Using External Library in Web Dynpro - Error

Hello,
I want to use an external library in a web dynpro. I use WAS 6.40 SP12.
1. I have created an dc web dynpro app
2. I have created an dc external library app
3. I have importet the jar to the external library
4. I have published the jar as public part
5. I have imported the public part to web dynpro
If I build the project I get no error. If I deploy an run the project then I get an error stacktrace:
java.lang.NoClassDefFoundError: com/sap/netweaver/bc/rf/util/uuid/UUID
NoClassDefFoundError - I think the jar-file was not deployed. What is wrong?
Greetings
Thomas

Hi THomas,
Please explain how you are adding the jars into the publicpart of the Libary DC.
You need to create 2 public parts .
1. Assembly
2. Compilation
You need to add your jar to above two public parts.
Then you need to add above two publicparts to your webdynpro application.

ALV report web (BSP and Web Dynpro)

Hi,
I want to display report results in a BSP table using a list viewer component.
I've found some classes for web dynpro that use ALV to print data results. Is there any way to use the same within a BSP application?
(Web Dynpro example that use an ALV table:
'WDR_TEST_DYN_ALV_USAGE'.)
Thanks and regards,
Maria

what ALV features you are looking for?
1. sorting - available in bsp tableview
2. filter - availalbe in bsp tableview
3. layout management (visible columns) - is doable with BSP (search weblog area for BSP personalize tableview)
4. export to excel - you can code that in BSP (code samples/special tag available in BSP weblog area)
but if you want a easy way out, as others mentioned, you can use integrated/standalone ITS to generate ALV and then use that its page as frame/iframe within you BSP

Abap error when using Web Dynpro assistance class

Hello All,
I created Web Dynpro component with assistance class.
On the component controller I can see the attribute "WD_ASSIST".
I also can use Goto -> text symbols and create net text key.
But when I tried to read the text:
wd_assist->get_text( '001' ).
There is abap error:
Method get_text is unknown protected or private.
I can see the method get_text inside my assistance class like this:
IF_WD_COMPONENT_ASSISTANCE~GET_TEXT visibility - public.
I think I missed something while creating the assistance class?
Thanks in advanced for the help.
Nir

Your method call should be:
wd_assist->IF_WD_COMPONENT_ASSISTANCE~get_text( '001' ).
You have to supply the interface name or go into the class definition and create a public alias for that method.

Shooping cart creation in SRM 7.0 using web dynpro ABAP classes.

Hi,
We have recently upgraded to SRM 7.0 from SRM 4.0. We are using customized portal application for the creation of the shopping cart.I am planning to create custom FM which will use the standard Web dynpro ABAP classes to create the shopping cart.
Could you please guide with the classes that are need to be implemented and the sequence of the classes used in the shopping cart creation.
I think these are the classes that are used in the standard web dynpro ABAP component.
CL_FPM_EVENT ->                  Creates an instance of this class based on an event ID.
CL_BADI_FLT_DATA_TRANS_AND_DB -> Data Handling: Transport and Database.
CL_EXITHANDLER ->               Class for Ext. Services Within Framework of Exit Technique.
CL_EX_BBP_DOC_CHANGE_BADI ->     BAdI Class CL_EX_BBP_DOC_CHANGE_BADI.
CL_BBP_OBJECTS_ACCESS ->         Access Functions for Object Types.
/SAPSRM/CL_PDO_BO_SC ->          Shopping Cart BO.
Your expert comments will be appreciated...

How to add new class to existing DC (Web Dynpro project)

Hi,
How can I add new class to an existing DC (Web Dynpro project)?
I tried adding it using File - New - Other - Java - Class, but after a build of the DC the new class (and its contents ) was completely removed.
Then I created a new DC (java project) and created a new class in that DC. This went fine, but I got into problems because of circular referencing between the new & the old DC, so no build was possible.
This can't be difficult, does somebody knows how to do it?
My temporary solution is to add the classdefinition to an exisiting .java file. Very ugly.
Thanks,
Jeroen

Hi Jeroen,
where did you create the class? If the *.java file is placed in the src/packages folder it should not be deleted by a build. (I suspect you created it in the gen_wdp folder?)

Marc

I know that this action can be handled in method IF_POWL_FEEDER~HANDLE_ACTION.
When pressing the button I want do call another web dynpro application.
How can I do this? -> Any Example Coding?
Thank you and best regards, Edgar

Hi Vineet,
it works, thanks a lot!!!! Best Regards, Eddy
P.S.: Here is the coding for triggering the event and passing parameters for the selected POWL table line:
METHOD if_powl_feeder~handle_action.

IF i_actionid = 'EDIT'.
*   Important: this triggers the event
    e_portal_actions-fire_wdevent = abap_true.
*   Pass parameters to event
    ASSIGN c_result_tab TO <lt_fligts>.
    lt_flights = <lt_fligts>.

    CHECK sy-subrc = 0.
*   Pass parameters
    ls_parameter-key = 'ACTIONID'.
    ls_parameter-value = 'I_ACTIONID'.
    APPEND ls_parameter TO e_portal_actions-parameters.
    ls_parameter-key = 'CARRID'.
    ls_parameter-value = ls_flight-carrid.
    APPEND ls_parameter TO e_portal_actions-parameters.
    ls_parameter-key = 'CONNID'.
    ls_parameter-value = ls_flight-connid.
    APPEND ls_parameter TO e_portal_actions-parameters.

Model class deleting in Web Dynpro

Hi ,
I want to delete few model classes which I imported from RFC which are redundant. Is there any way I can delete these classes.
From the ABAP end also few RFCs have been deleted and now I am getting error at the Web Dynpro end.
Your reply greatly appreciated.
Regards,
Rakesh

Hi,
Delete the model node from the custom controller which is bound to the RFC node during the mapping. and also delete the methods created in custom controller to call the execution of RFC. then remove the model from the used models area. Reimport the model and do the mapping steps.
