Webdynpro application to find forntend printer name

Hi Experts,
My webdynpro application(runs within SAPGUI) is to print the smartform in local user printer. I'm using function module rspo_frontend_printer_for_dev to find the local windows printer. This function module logic is running fine in SE38 ( ABAP editor) to get the default windows local printer name in export parameter value in prdefault <longprintername> but if I use the same function module in Webdynpro application it give export parameter value in prdefault <__default> (which is not giving the longprintername).
How do I get the local windows default printer by using this function module or Is there any other approach I need to follow to get the printer name?
Note: This application does not required PDF print preview. I have also used submit program logic in webdynpro to call zreport program(using same function module) to find the local windows printer name but it give the same output prdefault = <__default> .
Your help is highly appreciated.
Thanks,
Raj

Hi Thomas,
As you said in this forum How to print the smartforms to the windows local printer from WD4A i will ask for the setup for each of these printers within the SAP backend print infrastructure
Thanks,
Raj

Closing a webdynpro application, should call a portal page

Hi All,
I have a requirement in which, after a webdynpro application is closed in portal, the portal should show the workset content from which the webdynpro application is triggered.
For example,
Wedynpro application Created is ZWDA1.
Two iviews are created in portal which refers to the webdynpro application ZWDA1, the portal Iview names are ZPORTAL_IVIEW1, ZPORTAL_IVIEW2.
Two worksets ZWORKSET1 & ZWORKSET2 are created in portal which refers to Iview ZPORTAL_IVEW1 and ZPORTAL_IVEW2 respectively.
Two roles ZROLE1 & ZROLES2 are created in portal which refers to workset ZWORKSET1 & ZWORKSET2 resepectively. These two roles are assigned to users ZUSER1 and ZUSER2, when these user logs into portal they will see the content of the workset ZWORKSET1 & ZWORKSET2 respectively.
Assuming ZUSER1 and ZUSER2 invokes the portal ivew ZPORTAL_IVEW1 & ZPORTAL_IVEW2, the underlying webdynpro application called is same. So in the webdynpro application only I need to write the code to close the application and call the workset ZWORKSET1 for ZUSER1 and workset ZWORKSET2 FOR ZUSER2. This differentiation I am not able to indentify in webdynpro application, I thought of using relative navigation.
Any suggestion to achieve this functionality is greatly appreciatable

To run an ABAP webdynpro application, do the users need sepearate login for R/3 and SAP WAS, for which SSO can be configured. or is it just one login required?
Thanks
Hardik

Thanks Thomas. I am creating a flow diagram for user logon process. Does below steps make sense?
1. Enter URL of webdynpro application
2. Enter User Name and Password
3. SAPlogon.exe and SAPLOGON.INI provides user Data and server information to Work Processor in WAS
4. Check User Name and Password information agains SAP User Directory
5. Give Authentication if successful.

Hello
It looks like that you had not installed the ADS(Adobe Document server) for the PDF type reports. Please check with your basis team if you want to configure ADS.
If you need the output as a sapscript then please do the sollowing steps:
(1) Execute transaction SM30
(2) Enter 'Table/View' as V_T5F99OCFT
(3) Select 'Maintain' option.
(4) Select 'New Entries' option from the Application Too
(5) Enter following entries:
     Logical Form Name    = HR_IN_EPF12A_99M
     Form Variant         = (Leave this field blank)
     End Date             = 31.12.9999
     Start Date           = 01.01.1990
     Form Type            = SAP Script (SSC)
     Def. Type            = (This field should be checke
     PDF Form Name        = HR_IN_EPF12A_99M
     SAP Script Form Name = HR_IN_EPF12A_99M

How to find path of a file in WebDynPro Application

Hello,
I have created a WebDynPro application. In this application i have created an XML file under
src->packages->resources. The resources folder i created myself.
I have also deployed the file on a remote server. This servername & portNumber can change too.
Now i want to get the handle of my XML file (which is present in the same jar) so that i can user it and populate it.
<b>The following code doesnt work:</b>
<i>File file =new File("WebDynProProjectName/resources/filename.xml");</i>
Regards,
Aayush

Hi
By default it puts it under resources folder. If you want to create your own path then
1. Create the XML file (eg. output.xml) to some location in the server (eg: c:\Test\files)
2. Create a HTTP alias(eg. Test) in the Visual Adminsitrator pointing to the file location (eg: c:\Test\files).
3. Set the linkToURL reference property to http://<<servername>>:50000/Test/<<XML file name>>
For creating the HTTP alias refer to the blog "Creating an HTTP Alias in WAS"
/people/renjith.andrews/blog/2005/03/31/creating-an-http-alias-in-was
Hope this solves your problem.

I have tried reloading the iTunes player but same thing happens after selecting it.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT as you start iTunes) then going to Edit > Preferences > Store and turning off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

Print functionality using PDF form in a webdynpro application

Hello! All
Currently, we have a webdynpro application and we need to provide the print feature to print the content of the iview display on IE browser. We try the File-> print feature provide by Microsoft through IE but this doesn't work. We are looking for any other option like print to pdf form. We don't know if it is possible. Is there any tutorial, help or anything that can help us to print to pdf form. Please share any other suggestion, comment and it will be much appreciated. Thank you very much.

Hi,
The content (which is a pdf content) can be exported as a PDF from a WD Application. For this you can use File Download control whose source is in the form of bytes (which is PDF content).
Do you have the PDF content already generated?
If so it is very easy to generate PDF from WD.
If you need further help, kindly let us know.
Thanks and regards

How to secure the Webdynpro Application name ?

Hi Experts,
I have a requirement to send the Webdynpro Application name to Outlook inbox where the users will logs into that application and they will see the view the data and clicks on some action(Approve or Reject).
Now the my client does not want send that actual Webdynpro URL to outlook mailbox as it is having some security issues(host and domain details). Instead of that, can we change the actual Application name to any custom name by changing the host , domain and etc, parameters ?
Thanks in Advance,
Regards,
Giri

Hi,
If you want to hide the application path, goto SICF transaction and then create an External Alias for your WDA application path and then send the Alias path name.
Suppose, you have the WDA application url as
host:port/sap/bc/webdynpro/<APPLICATION_NAME> . Instead of this you can just show
host:port/sap/<Your Name> ( or any other) using Alias.

Kiran

I guess I have to add some -P option but have no idea where to look for or set the printer name.

Got it. In the large pages of hplip documentation I didn't notice that I just need to
1. plug the printer in
2. type
# hp-conf
And now it works

How to find windows default printer name

Hi Experts,
I have one requirement.....smartform should print in local default printer.
you might be known in windows we can set default printer name .
Suppose when the user executes my program, smartform should print in the default windows printer. not sap default printer. I tried by giving printer name as LOCL. In that case it is displaying pop-window by showing printer name. I don't want to see that pop-up window.
If I pass printer name in the smartform function module.. it is not displaying pop-up window and printing directly.
For this we need to findout what is the default printer of that particular system.
I think ... there will be method / FM to findout the front end default printer name...
Pls help me..
Thanks in advance
Raghu
Edited by: r badveli on Apr 17, 2009 4:46 AM

Hi Raghu,
Check the following tables to fetch the printer settings of a user.
TSPUSRSEL - Spool: User-Specific Settings
TSP03D Spool: Device Description (New Format)
So that you can use this detail and can fill the printer name.
Hope this will be useful.
Thanks,
Rajesh.

thanks in advance
Gaurav Makin

Hi Gaurav,
It is pretty easy to use the MSAccess as a back end from the webdynpro applications. Take the driver as a JDBC-ODBBC driver and creat the alias name for the database server to use as a data source.Select the model as a Beanmodel while creating a model in the Webdynpro explorer.
please find the below code which will help you lot.
Please let me know if you need any further information.
