Integrating Help files in Web Dynpro Application

The requirement is : To give context specific help for each fields..
Description:The requirement is to provide context specific help..for each field that would appear on dynpro screen..
Now what that means is.. for each field on the screen...there will be a "?" icon next to it..when the user clicks on that "?" icon...a small pop-up type of information. box should come up...displaying the text corresponding to that field..this u might of seen on some of the web sites...or microsoft applications..
       No we have to store the help files..in some proper place either KM...or anywhere...and maintaining the relationship between the field and it's corresponding help file.One of the option for this is to use microsoft help tool which creates files in the .chm format and then use these files for our purpose.
       So can anyone please guide me what's will be the best way to achieve my purpose .chm files where i the help files will be stored and how they can be accessed in Web Dynpro Application.If u have any good suggestion apart from using .chm files then please suggest me.Please try to give a detailed solution.
     Any direction will be appreciated even if just to the proper place for a forum post of this nature or documentation
that will send me down the right path.

Hi Candace, thanks for your time!
Nothing is "clickable".... as in, nothing will is hyperlinked to each individual file....
In my settings for items in this region, I have chosen mime type image, Image or Display Name Link, and when updated as attributes....
All that appears for each item/file is Image or Display Name and item updated info, though neither of which is clickable, or hyperlinked.....
Arrrrrghhhh..........

Error While uplaoding a EXCEL file in Web dynpro - HR_KR_XSTRING_TO_STRING

Hi,
I am getting an error while uploading an excel file in web Dynpro application. i am using the HR_KR_XSTRING_TO_STRING this function. I am getting the following error message 'Unable to interpret as a number'.

First of all, are you sure you know what you are working with here. If this is standard Excel file in the Microsoft binary/propriatery format there is not function module or class in ABAP that can magically just transform this to a character string. You should search the forums as this has been discussed extensively. On that topic, please also do not post duplicate threads. I have already locked your other thread with the same basic question.
Instead of the binary/propriatery format of Excel, the file should be saved on the client as a text based format - like XML or Text Tab Delimited. You can then use several different options on the server to convert the XSTRING to STRING and process the content (becuase it was text based to begin with). You could use CL_BCS_CONVERT, the function modules in the function group SCMS_CONV, or the class CL_ABAP_CONV_IN_CE.

R/3 search helps in java web dynpro

Hello,
A customer of ours has some Z transactions in its R/3 system, which basically present a very simplyfied version of MIGO. This Z transaction makes extencive use of Search Helps, which in some cases have been extended.
A ABAP developer with some Web Dynpro experience showed me that it was easy to integrate these search helps into his web dynpro application.
I cannot find how to do this in java web dynpro with the developer studio. Is this possible and if yes, how?
Greetings, Walter.

Hi Walter,
You can use search helps in Web Dynpro for Java also. The feilds with check table in R/3 automatically give search helps. To provide explicit search help you need use EVS or OVS.
These are the tutorials

Delete a file from the KM in a Web Dynpro application

Hello,
We need to delete a file from the KM in a Web Dynpro application.
We have a file name (filename.txt) and its path (/documents/Test/), how can we completely delete the file from the KM?
Thanks,
Gil

Hi venkata reddy,
You wrongly mentioned system admin instead of content admin
Go to Content administration not in the system administration
if u delete the file manually in the portal you can go with
go to Content administration -> KM Content -> go to Particular document -> just tick the check box which doc u want delete -> go to selection -> u will find delete .

Trigger File Generation to a Server from Web Dynpro Application

Hi Everybody! Hope you had a good new years eve
Is it possible to generate a File on a Server outgoing from Web Dynpro?
I tried to use GUI_DOWNLOAD. But as I couldn't use the GUI_DOWNLOAD from the Web Dynpro, I wrote a Report "ZCMI_EXPORT_FILE" that generates a Text-File. When I start the Report by myself, the file gets generated. All fine.
To be able to generate the File from Web Dynpro, I created a Batch Input Function Module, that I call in the Web Dynpro. The File is not created and it does not show any errors.
Do you have any idea how i can get this working? I'd also be happy with a different approach.
Best Regards and Thanks,
Steffen
REPORT that is called with Batch Input from Web Dynpro:
call function 'ZFM_GENERATE_EXPORT'
exporting
 it_detail_record = lt_records
 is_export = gs_export
importing
 ev_string = gs_export-document
 et_dataset = data_tab
exceptions

endif.
concatenate '\\SERVER\EXPORT\' gs_export-filename into lv_filename.

endif.

HI,
GUI_DOWNLOAD does not get's executed in the Backgroud.
there is no way to do it as a background job.. create the folder.. transfer the file to the application server in the backgorund using OPEN DATASET... use the tcode CG3Y to download the file from the app server to your folder..

Custom seach help for standard field in Web dynpro application

Hi All,
I have a requirement in SRM portal where in I have a to add a custom search help to the 'WBS_ELEMENT' field in the the 'ACCOUNT ASSIGNMENT' tab of the Shopping cart creation screen with some input parameters on the search help.
As the SRM Shopping cartcreation screen is a standard web dynpro application.
Can anyone help me in this regard for addition of search help for a field with some custom fields in the Search help screen.
Any inputs will be very helpful.
Thanks in advance.
Regards,
Ahmed.

Hi Ahmed,
If it is an standard application then you will have to do ENHANCEMENT in the component. And for using customised value help you will have to declare attribute in CONTEXT and dynamically change the binding of the Value property of UI element inside post-method of WDDOMODIFY. You can create your own customised value help for newly added attribute.
Thanks,
Vishesh

Cannot deploy web dynpro applications

Hello,
I'm starting to develop web dynpro applications, and I can run them on the nwds, but I cannot deploy them to the SDM, i always get the following error:

I would be appreciate if anybody could help me with this issue.
Regards,
Leandro Fonseca

At the same time if more users are deploying then you may such 'deployment aborted' errors check if there are more child instances for the J2EE engine.If not ask your basis administrator to create more child nodes to balance the load on the server instance.Also You can find out the server details at
"http:
<hostname:portnum>\index.html"select system configuration-you can get the details of the SDM and the j2ee engine from there.You need to have proper credentials to get the information from the above url.
Provide those details in the NWDS.

Source code for "Creating an Extended Web Dynpro Application"?

Hello!
I'm a rookie in the field of SAP Netweaver and I'm justing getting started with some tutorials. My problems with "Creating an Extended Web Dynpro Application" are to massive to be posted on this forum in this stage. What I want to have some help with is to find the source code for that tutorial so I can get som guidence from there.
Following text is cut out of this page:
http://help.sap.com/saphelp_nw70/helpdata/EN/5d/f42fef2eec724597a03b6bcc670c2c/frameset.htm
Creating an Extended Web Dynpro Application
You can download the Web Dynpro project for the current tutorial from the Software Developer Network SDN (http://sdn.sap.com -> Web Application Server -> Web Dynpro -> Sample Applications and Tutorials) in two versions: one skeleton version you can use for exercises and one final version (solution) for an immediate build, deployment and run on the Java engine of the SAP Web Application Server.
How hard I try I can't find the specific source code on sdn.sap.com
Does anyone have a clue where it is?
Thanks!

Hi!
I did what you said but I seem to miss the IDE folder. This is what it looks in my Explorer
C: > Program Files > SAP > IDE > CE > eclipse > (no folder called "examples")
I also did a search in this eclipse folder for "examples" but I did'nt find the example I'm looking for
I am running a newer version of NWDS:
SAP NetWeaver Developer Studio
SAP NetWeaver 7.1 Composition Environment SP03 PAT0000
Maybe that's why things don't look the same?

How To Consume UME services in Web Dynpro applications

Dear Friends,
I am developing a new web dynpro application in which i want to get the user related information in my dynpro code. I have used com.sap.secuirty.jar file in class path -> lib of my project.
I have written code sth like this.
IUser user = null;
String username = user.getCurrentUser().getSAPUser();
and defined sap.authentication as a application variable to fetch user creadentials from portal run time.(user logs in to the portal and dynpro application fetches user credentials from portal). When i do this, the login window appears twice and user needs to enter his credentials more than once. If I remove sap.authentication parameter from the application then i am not able to get the user credentials. Could you please tell me the right method of fetching the user credentials in web dynpro application? Do we need to use sap.authentication? do we need to include sharing reference of the usermanagement in our application?
kindly share your knowledge.

These might be good places for you to start.

HI ,
Set the application time out property to a value as per requirement.
Please follow below links for more details it may be help ful.

http://help.sap.com/saphelp_nw04s/helpdata/en/2a/7a754297fdd142e10000000a1550b0/content.htm
If application time out is set correctly check for the disk space available in server or log file space (basis person will do this).
Please check SDN , there are many posts available on this.

Running ABAP Web Dynpro Application without host entry of web server

Hi All,
I am trying to run a web dynpro application, its working fine when I have done host entry (host nam.domain.extension) of web server.
But when I remove this entry from host file it not runs.
Can you tell me the posibility of running this application without host entry? Based on this possibility I have to proceed my work. Please guide me.
Thanks and Regards

Using a Deployable Proxy in a Web Dynpro Application

Hi,
We have a Web Dynrpo application whose model is built from a set of Java business objects (POJOs.) These Java business objects currently make calls to a back-end R/3 system using JCo. We would like to provide the ability to allow the calls to be made over Web Services to the back-end system.
To call the RFMs as web services we have created a Deployable Proxy project, added the proxy as a public part, then referenced that public part in the web dynpro application. At this point we can write code to call the web service that looks something like:
InitialContext ctx = new InitialContext();
Object serviceObject = ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSService service = (Z_MRDM_GET_PLANTSService)ctx.lookup("wsclients/proxies/meridium.com/rcmo~proxies/com.meridium.rcmo.ws.proxies.plants.PlantProxy");
Z_MRDM_GET_PLANTSPortType port = service.getLogicalPort();
Z_MRDM_GET_PLANTS plantParameter = new Z_MRDM_GET_PLANTS();
plantParameter.setI_PLANTID(id);
plantParameter.setI_PLANTNAME(name);
Z_MRDM_GET_PLANTSResponse response = port.z_MRDM_GET_PLANTS(plantParameter);
MT001W[] plantArray = response.getET_PLANTS();
The problem is that when I call looup to retrieve the service implementation I get a ClassCastException.
The tutorials for using a proxy in web dynpro all assume that the web service is what the model is based upon but that's not possbile for our scenario we need to call the proxy from the business objects which are the basis for our model.
According to the help documentation for consuming a deployable proxy in a JSP page:
<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm">http://help.sap.com/saphelp_nw2004s/helpdata/en/2d/b9766df88f4a24967dae38cb672fe1/frameset.htm</a>
It discusses adding JNDI mappings. Is this what's needed for the reference to work in a Web Dypro application too? If so, how would one add the JNDI mappings references to a Web Dynpro application?
Many thanks!

Hi Dheeram,
I'm not certain about JSPDynpage specifically, but in a general J2EE Enterprise Application project you can add a reference to the application-j2ee-engine.xml file. For example here's the content of an application-j2ee-engine.xml file that references a proxy:
