Web Dynpro Code Wizard in WDJ??

Hi Guys,
in Web Dnypro ABAP I frequently use the Code Wizard Tool to generate source code, call methods in controllers etc.. I guess you know what tool I mean..
Is there such a thing for Web Dynpro Java as well?? Let me know!!
Later, Johannes

Hi,
there is no code wizard in webdynpro Java. But You can use cntrl+space to see methods.
Example you just type wd then press cntrl+space then you can see all the interfaces and classes starting from wd like wdcontext,wdcomponentAPI etc. After that press dot(.) and see the methods under it.
I hope it helps.
Regards,
Rohit

Web Dynpro Code Wizard doesn't have context tab

When doing web dynpro development and when clicking the Web Dynpro Code Wizard, I can't see the context tab. It looks like this: [http://twitpic.com/z2q92]. In other SAP systems I have seen the wizard look like this, where it has two tabs one of which is the context tab: [http://twitpic.com/z2qgh]. As the context tab is very useful, I would like to know how to get it to display.
I have searched in the SE80 settings and can't find any option related to this. I also searched the forums here and could not find any related posts. We're using the 700 release level 13 (as seen in this screenshot: [http://twitpic.com/z2qkf]). Is there something I can do to make this tab appear? If we need to implement a note or a newer support pack, which one would it be?

As you stated the system without the context tab is NetWeaver 7.0. The context tab and the extra wizards were new features in NetWeaver 7.0 Enhancement Package 1. Your system would have to be updated to this NetWeaver Enhancement Package level in order to have this functionality.

Web Dynpro Code Wizard - code patterns

Hello,
the code patterns that are generated by the very helpful Web Dynpro Code wizard seem to be a little inconsistent in their syntax structuring.
If I were to ask the wizard to read me a context node - I would get something like (some bits removed for brevity):
data lo_nd_result type ref to if_wd_context_node.
data lo_el_result type ref to if_wd_context_element.
data ls_result type wd_this->element_result.
* navigate from <CONTEXT> to <RESULT> via lead selection
lo_nd_result = wd_context->get_child_node( name = wd_this->wdctx_result ).
* get element via lead selection
lo_el_emp_search_result = lo_nd_emp_search_result->get_element( ).
* get all declared attributes
lo_el_emp_search_result->get_static_attributes(
    importing
      static_attributes = ls_emp_search_result ).
Yet if I were to ask the wizard to generate a message I would get:
* get message manager
data lo_api_controller     type ref to if_wd_controller.
data lo_message_manager    type ref to if_wd_message_manager.
lo_api_controller ?= wd_this->wd_get_api( ).
call method lo_api_controller->get_message_manager
   receiving
     message_manager = lo_message_manager
* report message
call method lo_message_manager->report_t100_message
   exporting
     msgid                     =
     msgno                     =
     msgty                     =
*     p1                        =
*     p2                        =
*     p3                        =
*     p4                        =
*     msg_user_data             =
*     is_permanent              = ABAP_FALSE
*     scope_permanent_msg       = CO_MSG_SCOPE_CONTROLLER
*     view                      =
*     show_as_popup             =
*     controller_permanent_msg =
*     msg_index                 =
*     cancel_navigation         =
*     enable_message_navigation =
   receiving
     message_id                =

post split to avoid silly size/formatting limits
Ok - both work - but one is using the:
result = class_ref->methodname( parameters = paramvalue )
and one is using
call method class_ref->methodname
                                  exporting parameters = paramvalue
                                receiving result = result.
As I often have to review code written by others, I encourage them to use these wizards - it helps speed code and prevents simple mistakes. But code that contains multiple different syntax structure approaches is harder to read (albeit only slightly), moreover - it looks sloppy.
But why are they not consistent in their syntax structure? (one could also argue why do we have multiple syntax structures for the same operation - but that's a different discussion).
Is there some way customers can update these structures to match with their own internal coding standards - or something we can change so that they go one way or another?
I look forward to other's thoughts on the same topic.
Cheers,
Chris

UI-Type using the Web Dynpro Dode Wizard

Hi,
every time i use the Web Dynpro Code Wizard and choose the Form i still get the UI-Element-Type "InputField". Is it possible to select ohter Element-Types for example DropDownByIndex or Text_Edit?
i hope we can fix this.
best regards,
Michael

Ofcourse you ca change it to UI-type that you want.
change the Standard Cell Editor to DropDownbyKey all the UI elements will change(Default it will be InputField because most of the forms contains more number of InputFields ), also you can change the individual context attribute UI type also by changing the CellEditor of a table Column.

MSS Web Dynpro code modification

Hi,
We are using XSS component on top of ECC 5.0. I need to make a small change to the standard Web Dynpro code delivered by SAP. Is there is an alternate way to modify the code without implementing JDI? Your thoughts are welcome...

GN

Hi Raju,
Could you please gice me pointers on how to go about modifying the standard SAP ESS/MSS Web Dynpro applications?
Is there any documentation for doing the same?

Web Dynpro Code Generator

Hi All
In webdynpro some files will be generated by "Web Dynpro Code Generator" internally and keeps in gen_wdp folder. One of the file (that is Internalview_XXX.java file) generated by this generator contains the methods which are duplicated there by at the time of DC build it is giving errors such as already defined
Thereby deleting these gen_wdp folder also does not solved my issues please any one can help me in this issue.
Regards
Prasad.

Hi,
You are correct - files in the gen_wdp folder are generated by NWDS using the WDP Framework.
Have you tried to edit these files directly? If so you will need to a second WDP project and create the view, then add whatever coding you did onthe older view. Finally you can delete the old view and replace it.
It is not guaranteed to work - but unless I have more information on what you are trying to do - I will not be able to give more help.
Hope that helps.
Thanks.

Experiences - Applying support packs to enhanced SAP Web Dynpro code

Just thought I might highlight some experiences we've had with applying support packs for XSS. (Reply if you have your own experiences or a proven better way)
Firstly, we are using Travel within XSS and have some significant developments to get this working globally. Rightly or wrongly, we added our own DC's within the ESS application area and need to take this into account during support packs.
As advised by SAP, we have not directly applied the support pack source code to the modified track, but created a separate SPXX track which we manually need to reaply all of our changes. It dissapoints me that SAP don't recommend doing what the help.sap.com states, but there must be a reason for this (supposedly the meta data tool not yet available in NW04 will address the main reason).
In order to get our custom DC's from the old track to the new; I needed to add all non-generated objects to an activity, connect SPXX-1 track to the SPXX track and transport all the way through to the approval stage to get it migrated (the connection can be terminated after this is done). Again - Less than ideal, especially if you accidentally transport a generated file or miss a file.
Then for all SAP Web Dynpro changes, we've documented all changes to the nth degree and it's at this point we manually reapply the changes - taking into account any SAP changes that may have occurred.
I hope SAP promotes doing this a better way soon, but here's a process for anyone else needing to do this.
Regards,
Matt

Search for users in a particular LDAP through Web Dynpro code...

Hi Experts,
Let me try explaining my problem. In my project we are using two ADAM LDAPs. One for storing internal users and the other for storing external users. I have configured the portal to connect to both the LDAPs. I am able to search for the users created in both the LDAPs through portal Indentity Management.
I am trying to search for the users in a specific LDAP through Web Dynpro coding... I am not lucky enough to get it done. Let me explain you what I did.
I created a custom attribute for UME through config tool. Gave a physical mapping for the custom attribute in dataSourceConfig_xxx.xml to the LDAP attribute distinguishedName which returns the distinguished Name for the user in ADAM LDAP.
For Example: Custom attribute in UME is ldapuser which is mapped to distinguishedName attribute in ADAM LDAP in dataSourceConfig_xxx.xml.
When I do a search for the users in a particular LDAP, I am trying to put a filter to the newly created ldapuser attribute to distinguish between the two LDAPs.
The search will result if I pass the value as '*'. If I try to specify the user path for the LDAP in this attribute it doesnt result any data.
For example:
userSearchFilter.setSearchAttribute(
     "com.sap.com.cust.admn",
      "ldapuser",
     "OU=16482515,OU=Members",
     ISearchAttribute.LIKE_OPERATOR,
     false);
The above code will not return the data, whereas
userSearchFilter.setSearchAttribute(
     "com.sap.com.cust.admn",
      "ldapuser",
     ISearchAttribute.LIKE_OPERATOR,
     false);
Will result with user list from both the LDAPs.
If anyone tried searching for users in a particular LDAP through code, please help me with this issue.
Thank you in advance.
Regards,
Rekha Malavathu

I just figured it out. Under "group-policy GroupPolicy_COMPANY_SSL_VPN attributes", I had to add "vpn-simultaneous-logins 15". Apparently, it was using the value "vpn-simultaneous-logins 0" under the NOACCESS group policy.

One section data of adobe form is not read by web dynpro code

Hi,
I am facing problem in adobe form integrated with web dynpro. Form is having Java script. There is a section in the form related to settlement rule of wbs. It can be added in the form by pressing add record button.
When I use this form offline and press add record and one section is added. I fill the data in those two section and upload on the portal to process online data in the second section is not reaby the code whereas in the first section is present there.
But if the same activity is performed online data is properly read by the code.
Could you please assist if there is any issue of saving data in the form offline and how it is handled in offline form.
Thanx..

Hi ,
Try this.
I think you have corresponding context node is in the WDP. using 'APPEND INITIAL LINE TO' just add some blank data to the context. .
Inside the form, create a table for the context node. so at run time all the empty entry will be displayed. Make this Table as hidden.
Create another Table that will display all the non empty row from the above hidden table. When ever we add / delete rows, the corresponding entry will update the hidden table. or else you can update the hidden table on the click event of SUBMIT .
Hope this will help you.

Web Dynpro Model Wizard Exception

Hi there,
I've recently installed the latest Netweaver'04 Sneak Preview and I get the following exception when generating an R3 Adaptive RFC model (using the "create model" Wizard):

Problem while moving Web Dynpro code from one env to other

Hi Experts,
I have developed some Web Dynpro program in Development Environment. The Web Dynpro program uses BAPI and gets data from R/3. I have to transfer the Web Dynpro program to Quality environment. When I am trying to compile, I am getting following error message:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'DT8_METADATA' in the SLD. No such JCO destination is defined in the SLD.
In Development environment, I have created JCOs called DT8_METADATA and DT8_METADATA. Is it important for me to create same named JCO in Quality as well.
Regards,
S

Hi,
the JCO destination names u have created in Dev also needs to be created in Qlty also with targetd destination msgserver.
This might helps you to run in Quality.

Exclusive Checkout - Web Dynpro codes from NWDI

HI, SDN fellows.
I imported the SC Configuration, and created the project of the DC. When I try to open the file, just wanna to view the codes (not plannig to change them). There is a pop up message with check box - "Exclusive Checkout".
What is the meaning of "check" or "uncheck" the "Exclusive Checkout"?
In my case (just wanna to view the codes, not planning to change them), should I "check" or "uncheck" it?
Thanks,
Kent

HI,
when you try to touch any file in DC which belongs to NWDI track, NWDS will ask you to create activity to insure you are not going to make any changes accidently..
when you just want to see the code, and have no intention to touch source, then just dont checkout it.
In your case don't check out anyhting, if pop up comes then just cancel it.
whatever Marlo said about exclusive check out is right.
not only you can exclusively check out your file but a complete DC also. so when you are working on any DC nobody would able to touch it, it becomes read only for every other user except you.

Service call and code wizard

Dear All,
I am working on ECC 6.0 with Eph2 and SAP_HR SP27, when i tried to create a service call to function module in the Adapt Context i am not able to view the check box for selection.
Also when i click the Webdynpro Code Wizard it shows only a template gallery with standard screen,from and table only, which is not not displayin the Web dynpro statement structure
What could be the possible reason?
Patch level update or Service activation ?
Could you help me out in the solving this issue?

> when i tried to create a service call to function module in the Adapt Context i am not able to view the check box for selection.
What checkbox can you not see? I am looking at that step in the Wizard and there isn't any checkbox - just a table control with the node type, name, object type, new name.
>Also when i click the Webdynpro Code Wizard it shows only a template gallery with standard screen,from and table only, which is not not displayin the Web dynpro statement structure
The Web Dynpro Code Wizard from the View-layout tab should only have the Screen, Form, and Table option. What else where you expecting. If you want the code generation wizard then you are in the wrong place. Form the method editor choose the Web Dynpro Code Wizard and you will get a completely different set of options than choosing the same option from the view-layout tab.

No NWDI activity asked while modifying the Web Dynpro java code

Hi,
We have 2 team in our project, one offshore team and one onsite team. We have NWDI also in our landscape.
I have created 1 project in my local NWDS from DTR using create project option from NWDI track , when i do any modification in that web dynpro code once it appears in my local NWDS, its asking for the activity, all this is fine.
But when my offshore team send me this project from offshore (offshore team also working on this project), i go to my local machine under C:\Documents and Settings\user\.dtc\0\DCs\xyz.org\.. (workspace, where all the project folders are created in my local machine ) and replaces the web dynpro project (which i created using create project option from NWDI track ) with the project which offshore teams gave me that is I copy paste the project folder I received from offshore team.
I closed the NWDS and reopened NWDS, i did repair and reload also, but now when i try to do any code modification in that project its not asking any activity at all. So i want to know the reason why its not asking activity at all while modifying the code.
if now i do any code changes, and since no activity is asked, it wont be transported to QA and Prd system.
Can anyone have any suggestion on this..

Hi GLM,
I think you might be right that some files are in read as well as write mode. I went to my local machine and checked the project folder C:\Documents and Settings\user\.dtc\0\DCs\xyz.org\testproject\_comp\.dcdef file , its not in read only mode, that is read only flag was not checked.
I again checked the mode of .dcdef file in other web dynpro projects which are asking for the activity in all those projects mode of .dcdef was read only that is read only flad was checked in .dcdef file. ( I am not sure is .dcdef file only giving this problem that si because of this file not in read only mode I am not asked for the activity)
So could you plzz tell me how to make in read only. when ever i click the read only check box of .dcdef file and reload the project in my NWDS. that read only check box is getting removed. how to do this..
regarding your query, landscape in offshore team and onsite team are different, client has not provided nay access to its landscape to ofshore team so offshore team can not check in / check out the code written by me and same applies to me I can not check in / check out the code written by offshore team , only option is offshore team do some changes in the code and send the project folder via email and I have to deploy in client landsacpe and do further modification.

BSP vs Web Dynpro ABAP

Hello,
we are looking for a listing that states the functional and technical differences between Web Dynpro ABAP an BSP.
Is there anybody who has come along such a list ?
Tx a lot in advance!
Best regards,
Ana

Annette,
check this
The SAP Web Application Server (WAS) provides a page-based programming model with server-side scripting as well as server page technology for developing, designing and implementing Web applications:
Business Server Pages (BSP). Server-side scripting enables direct access to all elements in the application server (such as function modules, database tables, ABAP Objects, and so on.).
We can create HTML pages or Business Server Pages (BSPs) with server-side scripting in ABAP or JavaScript.
The HTMLB and XHTMLB HTML Business libraries are available as BSP Extensions for a uniform layout and its associated usability advantages.
And In the Web Application Server, the presentation layer is separate from the business logic. This makes it possible to implement front-end technology.
Why BSP NOT WebDynpro
                          BSP
              ABAP WEBDYNPRO
Currently PMUSA/JMC customers are using Fire fox (Mozilla), Internet Explorer and Netscape navigator web browsers to access WEBUYPM application.
BSP supports these web browsers.
Restricted (Some of the features will not be supported by WebDynpro)
Existing WEBUYPM application is written in HTML, Business HTML and JavaScript language.
BSP supports these languages. And it allows even to mix ABAP, HTML and JavaScript thus has more flexibility to convert WEBUYPM application into BSP.
Web Dynpro does not support HTML/JavaScript.
Existing WEBUYPM displays the trade communications (Information tab) based on JavaScript and custom configuration file
BSP supports JavaScript, we can display the trade communications in BSP too.
Web Dynpro does not support Java Script.
Existing WEBUYPM application has different colors schemes, Logos and graphical elements for PMUSA/JMC companies.
BSP support s multiple color schemes/logo. These color schemes can be set dynamically based on company code selection at runtime.
Separate Themes has to be developed for each User Interface elements.
Development effort needs to be involved to even display a logo.
BSP supports client side (user) validations. As most of these validations can be done at client side, the no. of hits on the server can be reduced and thus giving better response for the user inputs.
In this way, performance can be increased.
Web dynpro does not support any client side validations, every time the request must be sent to server to validate the useru2019s input. This increases the traffic and reduces the performance
WEBUYPM application has logos, images.
BSP supports Client side caching, and thus loads these element from client side very quickly.
Web dynpro supports very little use of caching on the client side, and hence quite a significant delay in starting on some customeru2019s browsers.
BSP has no restriction on user interface possibilities, Ex. Grid, drop down boxes, Font colors, size etc.
Significantly more restrictive in user interface possibilities.
Ex. Only those fonts, which are provided by SAP, can be used.
Appearance can be changed dynamically using same web pages, to support different colors for different companies.
We can have same (or better) look and feel if we convert the application into BSP.
As there is no HTML coding involved in web dynpro the same look and feel as we have it today can't be achieved by using web dynpro.
BSP is built for developing any type of web application (including mobile applications. It can be accessed from desktop, laptop, and any kind of smart devices like PDA.
Web dynpro applications can not be accessed from PDA s (Not possible)
Why WebDynpro NOT BSP
             ABAP WEBDYNPRO
                           BSP
Personalization can be given to the end user if they do not want see any of the user-interface elements.
We can not hide any of the user-interface elements (Ex buttons ex) during the runtime.
Note - Current WEBUYPM application does not support any of these options.
Currently we are setting/retrieving the runtime context values in a session.
Web dynpro supports State full applications.
No additional development would be required.
BSP also supports to set runtime values and to retrieve the runtime context values, but minor development would be required to achieve this functionality.
Currently users can see view source for WEBUYPM HTML pages.
Using Web dynpro this can be restricted thus providing more security to the application.
HTML view source can be available to the users, Users can see the HTML client side code (not server side coding) as it does today.
By using Adobe Flash Island, powerful web pages (RIA) can be created.
But, Flash Island comes with Net weaver.
BSP does not support Flash Island. But, BSP supports Java Script.
JavaScript is essential for the new trend of rich internet applications (RIA), it is used by all the new applications, Ajax, Widgets, Flash, and even Microsoft is supporting JavaScript for the new generation of RIA
Web dynpro has wizard tools to generate the code to create/configure the User Interface elements.
Development effort would be required to create UI elements.
We dynpro has uniformity as we use standard colors provided by SAP
Uniformity can be achieved by using style sheets (minor development would be required).
Thanks
Bala Duvvuri
