Custom Enumeration Type and Dropdown in Web Dynpro Java

Hi Everyone!
I have developed a custom enumeration type named com.agile.pmg.politicrh.customtypes.status.
I can see correclty the dropdown with the enumeration in Service Browser with all values I have put, but I need to be able to see these values in web dynpro too. But if I create a attribute of type com.agile.pmg.politicrh.customtypes.status in web dynpro and map it to a dropdown, it doesnt show anything. The enumeration is empty.
Does anyone know what is the problem?
Bests Regards!

Create a Table Dynamically in WEB Dynpro Java with diferent type of column

Hi everyone, I have a question if is possible to create a table dynamically in Web Dynpro Java?, depending of the RFC consults create the rows dynamically, ,this table must have diferent type of columns, for example link column (when the user click this link execute an action and show a adobe interactive form in another view), image column (show an image depending of the information)
Thank you everyone

Hello,Israel.
Yes , it is possible through dynamic programming in wdModify of the View.
You can do this ,for example, using cell variants.
IWDTable tab = (IWDTable) view.getElement("TABLE_NAME");
IWDTableStandardCell cellV= (IWDTableStandardCell) view.createElement(IWDTableStandardCell.class,"TableStandardCell"+i);
cellV.setVariantKey("NotEditableVariant");
cellV.setCellDesign((WDTableCellDesign)wdContext.nodeTableDaysTitle().currentTableDaysTitleElement().getAttributeValue("CellDesign"+i));
IWDTextView textViewi= (IWDTextView) view.createElement(IWDTextView.class,"TextView"+i); // -- here you control the type of the object that is displayed in the cell
textViewi.bindText(dayAttrib);
cellV.setEditor(textViewi);
tabColumn.addCellVariant(cellV);
tab.addGroupedColumn(tabColumn,tab.numberOfGroupedColumns());
Using this code you can control even specific cells in the table and not only columns.
Hope this helps you,
Constantine

Caching in Web Dynpro Java

Hi Experts,
I am trying to develop a web dynpro for java application based on RFC model.
I am using an RFC that brings the Countries and States from the R/3 and will be used as dropdowns in the views controllers.
The question is:
I would like to cache the Countries and States in my web dynpro application. The idea is not to execute the model everytime. The model should be executed only once. I would like to store these countries and states in a local java dictionary or etc. and use them for UI element designing.
Is there any way to do this in Web Dynpro Java? I would like to follow a better approach to avoid performance problems.
I do not want to follow this approach: executing the model in the wdInit method of the controller. Executing this model in this method also causes performance problems. Because the model is brining approx 1540 records from R/3.
Please advice.

Hi All,
Thank you for the suggestions.
I am a beginer in wd java. i am starting with amit's suggestion.
Step 1: Execute RFC to fetch data preferably use doInt method for it.
Should I execute the method in wdInit of the view controller/component controller?
I defined a method "executePMPReadBAPI" in component controller.
public void executePMPReadBAPI( )
    //@@begin executePMPReadBAPI()
   try{
        wdContext.currentPMPDoctorReadElement().modelObject().execute();
        }catch (Exception e){
        logger.errorT("Error in executing PMP Read BAPI");
wdInit of View controller:
          IWDAttributeInfo countryInfo =
               wdContext.getNodeInfo().getAttribute(
                    wdContext.currentContextElement().COUNTRY);
          ISimpleTypeModifiable countryType =
               countryInfo.getModifiableSimpleType();
          IModifiableSimpleValueSet countryValueSet =
               countryType.getSVServices().getModifiableSimpleValueSet();
          for (int i = 0; i < wdContext.nodeCountries().size(); i++) {
               IWDNodeElement CountryNode =
                    wdContext.nodeCountries().getElementAt(i);
               String countryKey = (String) CountryNode.getAttributeValue("Land1");
               String countryText =
                    (String) CountryNode.getAttributeValue("Landx");
               countryValueSet.put(countryKey, countryText);
This coding is working, I am able to populate the dropdowns. The problem is the application is slow.
I am guessing this much coding is not necessary in the view conroller's wdInit method.
Why the binding approach like mentioned below is not working (model>Conroller>View)? How should I execute the RFC in the wdInit of the component controller? Is this possible?
wdInit of Component Controller: Below coding and proper binding is not sufficient to populate dropdowns? Please advice.
     Zhr_Ess_Address_Input ReadInput = new Zhr_Ess_Address_Input();
          wdContext.nodeZhr_Ess_Address_Input().bind(ReadInput);
          try {
               wdContext
                    .currentZhr_Ess_Address_InputElement()
                    .modelObject()
                    .execute();
               wdContext.nodeOutput().invalidate();
          } catch (Exception e) {
               logger.errorT("Error Reading the BAPI");

Problem when generating an non-interactive form in Web Dynpro java.

Hi,
I'm trying to create a PDFDocument using a creation context in java. Everything works fine when the Interactive property of the creation context is set to true. When I change it to false however, the Web dynpro application hangs and eventually throws the following exception:
java.net.SocketTimeoutException: Read timed out
   at java.net.SocketInputStream.socketRead0(Native Method)
   at java.net.SocketInputStream.read(SocketInputStream.java:129)
   at java.io.BufferedInputStream.fill(BufferedInputStream.java:183)
   at java.io.BufferedInputStream.read(BufferedInputStream.java:201)
   at com.sap.engine.services.webservices.jaxm.soap.HTTPSocket.readLine(HTTPSocket.java:806)
I'm wondering why this exception occurs when i'm generating a non interactive form and never appears when i'm generating a form with the Interactive property set to true.
Any ideas?
Edited by: Arjan Nieuwenhuizen on Feb 25, 2008 3:24 PM

Yeah I know changing the form properties will solve my problem, but since i'm developing a training for Interactive Forms in Web Dynpro Java, I wanted to figure out why the (static / non-interactive) combination didn't work, turned out to be a template problem, which i still didn't figure out, except the fact that having flowed content on your template is not the problem.
My ideas about your question:
When we have the layout of an Interactive Form, its clear if it's meant to be static or dynamic, we don't know however, if it's interactive or non-interactive.
I don't think we can judge a layout to have an Interactive or non-interactive purpose, can depend on the situation in which the same form is shown/used:
- One moment it can be interactive, e.g. user is filling in the form, can enter data etc.
- Next moment it can be non-interactive, e.g. form is shown to another user.
So it's more the scenario/situation that determines if the form is interactive or non-interactive.

SUBMIT(to SAP) Button in Adobe Interactive Forms (Web Dynpro Java)

Hi ,
I m using Adobe Interactive Forms with Web Dynpro Java
But submit to SAP button is not working
i m using NWDS 7.2 with adobe lifecycledesigner 6.0
with adobe reader 9.0
when i click submit to SAP button in interactive form nothing happens and
data is not transfered into web dynpro Context
Can anybody help me out................

Hi Adi,
The evniorment and versions you posted seems to be quite scattered, make sure all are of compatible and to the lates.
Anyways this was not the reason for your problem.
Can you tace if the button click event is triggered ....?
1) when the PDF is published can you see any of the fields editable...? reason behind is generally when you create a form in ADLC it comes up in static PDF format if its so you need to make it dynamic.
I dont know if adding the webdynpro script to your form might fix.

Sai

Where Web Dynpro Java version of Adobe Forms are used in ESS MSS

Hi, SDN Expert.
I am working on research the use of Adobe Interactive Forms in the current processes of HCM ESS MSS.
We are on ECC5.0, EP7.0, and ESS MSS SP21. We are in the midst of upgrading to ECC6.0.
Do you know where Web Dynpro Java version of Adobe Forms are used in ESS MSS are used? OR are they all in Web DYnpro ABAP version in ECC6.0?
Thanks,

Moving from Web Dynpro Java timesheet to Web Dynpro ABAP timesheet

Hi
We are in the process of moving from Web Dynpro Java ESS timesheet to Web Dynpro ABAP ESS timesheet. When using Web Dynpro Java ESS timesheet it is possible to enter time using a daily or weekly view.
When using the Web Dynpro version and ensuring the period type is set to weekly view for the data entry profile it is only possible to enter time on the weekly view, the tab for the daily view is no longer available.
Still using the Web Dynpro version and changing the period type to daily view I can enter time using the daily view and the weekly tab also becomes available, but the weekly tab is read only.
Do you know if it is possible to make daily and weekly timesheet entry for one data entry profile.
Thanks
Mark

Yes you can have only one view ie weekly or daily as per your CATS profile in CAC1.
but of course you can select multiple profiles
Configuration
The application configuration HRESS_AC_CATS_1 is provided by default and allows you to provide default values for the application parameters. It also allows you to specify the layout and appearance of the application.
The following application parameters are provided:
HIDE_CLOCK_TIMES_IN_WEEKLY
Hides the clock times in the weekly view.
MULTIPLE_PROFILE
Enables the selection of multiple data entry profiles from the dropdown list

Advantages and dis advantages of web dynpro java

Hi Guys,
May i know what are the advantages and dis advantages of web dynpro java?
Regards,
Madhu

Hi Madhu,
Web Dynpro (WD) is a proprietary web application user interface technology developed by SAP AG and exists in a Java (Web Dynpro for Java, WDJ or WD4J) and an ABAP (Web Dynpro ABAP[1] , WDA) flavor. Both have in general the same functionality, but usually one flavor is improved after the other, so temporary one flavor is more advanced than the other. Hence, the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
WD follows an adapted MVC pattern and a model driven development approach ("minimize coding, maximize design") with a large number of dedicated hooks in generated code to place custom coding. It is intended for business applications that shall follow standardized UI principles, connect to backend systems and be scalable.
Main advantages of Web Dynpro over other technologies
typed access for design time checks, e.g. navigation links and messages are accessed via types instead of string keys like in JSF
diverse services for backend access, like aRFC, JEE and Web Service data models
integration with SAP Interactive Forms by Adobe, which are interactive PDF forms, during design (same IDE) and run time (data sharing)
integration with business process management and business rules management (since NetWeaver CE 7.1 EHP 1)
designed to support development big scale applications by adding multiple grouping layers on top of Java packages (DCs, SCs, products)
runs on different clients e.g. web browser, mobile device, widget engine
comes with a big collection of UI elements providing a wealth of functionality and only have to be configured but not programmed
Main disadvantages
proprietary, running only on SAP servers
less flexible due to support for multiple clients (i.e. custom html is not possible). To reduce the limitations, several measures have been taken. For example, WD supports so-called "islands" for e.g. flash applications that enrich the Web Dynpro UI element collection by rich UI elements. This disadvantage doesn't seem so serious but in fact basic features that user expect to receive cannot be implemented (e.g. coloured rows in table, colours in general, advanced aligning of simple UI elements (due to nonexistence of more complicated ones), selecting multiple rows in tree-like tables (this is due to preserving basic concept of WD) and many more). Having the flash feature means that developer completely avoids WD UI (And thus cannot use other features).
rendering speed in browser for larger tables (>1000 rows)
The designtime and runtime environment is part of SAP NetWeaver 7.0[2] (also known as Netweaver 2004s) and following releases.
The name comes after the original Dynpro library, whose name meant "Dynamic Program".

Pradeep Kumar

Logical Destinations in Web Dynpro Java

Hi!
Is it possible to access logical HTTP destinations maintained in SAP NetWeaver Administrator via Configuration Management -> Security ->Destinations in Web Dynpro Java source-code.
I would like to use such a destination to configure an URL target for a IWDFrame UI element.
Thank you very much in advance!
Regards,
Thomas

I found out that there is a [Destination Service API|http://help.sap.com/saphelp_nwce711/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm] for this purpose. Unfortunatly I am still not able to provide the required components security.class and tc/sec/destinations/interface to the web dynpro component. Maintaining them via Project Properties -> Web Dynpro is not allowed any more, and I couldn't find them in the DC perspective to add them as DC dependency.
Has anybody got an idea where these two libraries have gone?
Regards,
Thomas
PS: The 7.0 procedure, which can be found in various posts, doesn't seem to work any more for CE 711.

Date Column not getting sorted in a table in web Dynpro Java

Hi All,
I am facing an issue while sorting the date column in a table in my web dynpro java application.
When the date is displayed in the sql format in tha table, I am able to sort the date column successfully but when we convert the date field from sql format to util format in our table and then sort it does not work.
Kindly let us know the steps to be followed in this case to sort the date column of a table in Simple Date format as we do not want date in the sql format to be displayed.
Thanks & Regards,
Anurag

Hi,
You might want to check whether both your browser's language settings are identical. The browser language could also determine the date format.
As a workaround, you could add an extra attribute to your context, and set the calculated property to 'true'.
In your table, add a new column and bind to this new attribute, and hide your original date column
If you sort using the date column that's hidden now, you could use the calculated field to fixed-format your date the way you prefer (by using the SimpleDateFormatter class for instance)
Cheers,
Robin

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
    I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
     procedure"
   Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
     signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks

Web Dynpro Java - Light Portal Desktop

Hi Guys... I have a web dynpro java application that I want to display on a Light Portal Desktop, but when I display the iview... it gets cut. I mean I can see only part of my application and there is also a right scroll bar... It looks like the height size of the iview is set to "FIXED" but it's not. I Actually modifed all values for size even on the Light Framework Page used...to FULL_SCREEN. I don't know what's wrong. If I display the same iview using a Default Framework Page it looks fine... I'm using SAP EP 7.00 SP 16.
Is there any restriction for using Web Dynpro iviews for Light Porta Desktops?
Thank you.
David

David,
Webdynpro content is considered heavy and I dont think we can use it in LPD.
