Add html code in web dynpro application

Hi
Is there a method to add HTML Code in web dynpro application so that it works same as HTML works in browser
I have to add a clock in my application How can i do that
Best regards
Suresh

If you're on NetWeaver CE or otherwise use Wb Dynpro for Java 7.2 or higher, you could use the WebWidget control, see http://help.sap.com/saphelp_nw73/helpdata/en/49/bfa3b2e55657bae10000000a42189d/frameset.htm
Otherwise, I'm afraid your only option is to use an IWDIframe component in your WDJ project, embedding the HTML.. Be carefulo though, the IWDIframe component is deprecated (since each server roundtrip forced a reload of the IFrame it was pretty useless)
Hope this helps!

How to include source code in web dynpro java deployment

Hi,
We dont have NWDI.
We are creating ear files out of web dynpro applications packaging them as sca files and deploying them in server.
But the source code is not included in ear.
How to include source code with your ear/sca , so that when anyone downloads the sca file later, they are build the Project in the studio.
How would they typically download? Do they require NWDI ,
Right now we dont have NWDI in place, but we want to do is parcel the applications such that the source code should be available at a later time for download.
This is possible with .par files , but what about web dynpro?
Thanks,
Deb

If you are not using NWDI use the _comp file.

How to call t-code from web dynpro ABAP application

Dear Gurus,
I am new to ABAP web dynpros. I have to add a button and have to call a SAP standard t-code if user clicks on this button? How to accomplish this task? Any help or example would be appreciated.
Thanks,
GSM

Hi GSM,
You have to create a SAP transaction iView in your Portal, then obtain its URL in your webdynpro and call WDPortalNavigation.absolute() method.
Below are the same steps in more detail:
1) Create a SAP Transaction iView or an Internet Application Component iView (whichever you find convenient). While creating you can select whether you want to use SAP GUI for windows or SAP GUI for HTML. For the latter(GUI for HTML) ensure that your ITS is working fine and configured while creating the system in EP.
2) Open the properties of the SAP transaction iView created. In the OK code field you can give the ok code value just as you give in SAP R/3 in case you want to navigate to the second screen of SAP R/3 when you pass values from WebDynpro.
Example for the above would be say Transaction "VA03" for displaying Sales order. Suppose from Webdynpro i want to pass a parameter called "Order number" and when i click a button it should pass the order number to R/3 and skip the first screen required for inputting the sales order numbe.
It should directly go to the main display of sales order for that ordernumber.
3) Create your WebDynpro component and deploy it on the server. In your WebDynpro use the WDPortalNavigation.absolute() method and give the url of the SAP Transaction iView created as a parameter and also the required parameters that you would like to pass from WebDynpro.
4) Create a SAP WebDynpro iView in the Portal.
5) Now run the Component. It should open up your SAP Transaction iview.

Problem with calling we02 transaction code from web dynpro

Hello everyone,
I want to skip the initial screen of we02 tcode for this i have created the URL, provided the idoc number and
used the function code DYNP_CODE=ONLI for execute button.
DATA : FINAL_URL TYPE STRING.
CONCATENATE 'host' '.port' '/sap/bc/gui/sap/its/webgui?~transaction=we02 DOCNUM-LOW='
ls_itab-docnum ';CREDAT-low=' ' ' ';DYNP_OKCODE=ONLI'
into FINAL_URL.
I am trying to pass the idoc number internally and click on execute button...so that the end user can see the idoc display directly, rather than clicking the execute button manually. But, unfortunately the function code for execute buttong (ONLI) is not working. In WE02 tcode, provided input values are appeaing correctly but not triggering the execute button.
Please help!
Thanks in advance...

Hi Rohit.,

How to get the Response Code when a URL is launched from Web Dynpro

Hello Experts,
I have a Web Dynpro Application in which in one of its views i have an IFrame UI element in which i will show a resource stored somewhere ..
But before showing it i want to check if the resource actually exists. For this i have to check the HTTP Response code from Web Dynpro Application without setting it in the Iframe..
I am using the following code to get the Response Code:
try{
URL url = new URL("Some Url");
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.connect();
wdComponentAPI.getMessageManager().reportSuccess("Response code ="+connection.getResponseCode());
}catch(Exception e){
wdComponentAPI.getMessageManager().reportSuccess("Exception");
Now the Problem is whatever response Code occurs 403 (for No Proper Authorization), 404 (for Resource not found) etc..
i always get Response Code= 500 (which is for Internal Server Error) shown in the messgae i have printed.
Please let me know the correct way of getting the Response Code from Web Dynpro.
Also my resource is lying on a SAP Portal 6.4
Best Regards

Hi,
Check this code from /thread/5242768 [original link is broken] if it works.
try{
URL myurl = new URL("http://calendar.google.com");
URLConnection connection = myurl.openConnection();
if(connection instanceof HttpURLConnection) {
HttpURLConnection httpConnection = (HttpURLConnection) connection;
HttpURLConnection.setFollowRedirects(true);
httpConnection.setRequestMethod("HEAD");
httpConnection.connect();
System.out.println("Response = "+httpConnection.getResponseCode());
catch(Exception e) {
// print exception

How to get Portal User Context in Web Dynpro application

I have successfully integrate a web dynpro app into SAP Netweaver Portal.
Within my web dynpro app, how can I get portal user context information such as first name, last name, job title or some newly created ume attibutes.
Is there any programmatical approach to get portal user context in my web dynpro. I not sure whether I can use the following codes in web dynpro?
IUserContext userContext = request.getUser();
String firstName = userContext.getFirstName();
String lastName = userContext.getLastName();
If yes, can someone point me the name of the jar file I have to import.
Note : The SAP Netweaver installation that runs my web dynpro app is same with the SAP Portal.

Hi ,
you can use the below code to get User details and add com.sap.security_2.0.0 > lib > com.sap.security.api.jar
try
IWDClientUser clientUser = WDClientUser.getCurrentUser();
String firstName = clientUser.getFirstName();
String lastname = clientUser.getLastName();
catch (WDUMException e) {
wdComponentAPI.getMessageManager().reportException("Error Retrieving User"+e.toString(),true);

Hi,
Try opening Visual Admin if your not able to login with username(administrator) and password. Problem with NWD2004s do the following steps.
C:\usr\sap\J2E\JC01\j2ee\configtool->configtool.bat->open it
1. Click on Secure store
2. Right you will find :
admin/password/J2E->retype your admin passowrd which you gave during installation=>SAVE properly
Restart the server and try login visual admin
Now you deploy.... Otherwise see this thread same problem but solved.

CAF DB Update for CAF Entity Service from Web Dynpro

Hi all,
I have created an entity service in CAF called Contacts which contains the following attributes.
phoneNo
cellNo
emailID.
Another entity service called "Person" is created. This contains the following attributes.
personId
personName
personAddr
contactsRef. (Cardinality -> 0..n , Relational Type -> Composition)
That means Contacts entity service is used within Person entity service. Now it is working fine within CAF service browser. Now the Web Dynpro DC of CAF application is used within another custom Web Dynpro DC project. I want to store data from Web Dynpro.
Within the context of component controller of Web Dynpro the structure is like
APerson
     |_ personId
     |_ personName
     |_ personAddr
     |_ contactsRef
                |_ phoneNo (Under contactsRef)
                |_ cellNo (Under contactsRef)
                |_ emailID (Under contactsRef)
So I have written the following code within web dynpro custom method.
APerson person = PersonServiceProxy.create();
java.util.List ls = new ArrayList();
for(int i=0; i<4;i++)
AContacts contact = ContactsServiceProxy.create();
contact.setCellNo("9092130156");
contact.setEmailID("[email protected]");
contact.setPhoneNo("432258");
contact.getAspect().sendChanges();
ls.add(contact);
person.setRelatedModelObjects("contactsRef",ls);
person.setPersonID("9999");
person.setPersonName("xyz");
person.setPersonAddr("ABC, KOL");
wdContext.nodeAPerson().bind(person);
person.getAspect().sendChanges();
CAFServiceFactory.getServiceFacade(idendityDefinition.class);
After saving the data from Web Dynpro I am trying to test it from CAF service browser. But I am getting only the parent row. I mean only the value of personId, personName and personAddr fields which I have stored from Web Dynpro. But no value is coming within the table for Contacts entity service for composition relation.
Could anybody help me how can I solve my problem?
Thanks & Regards

Hi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.

Display XML in Web Dynpro

Hello,
i have a string variable filled with xml. And now i want to display this code in Web Dynpro with an ui element.
I tried a text_edit but it only shows the text but i want it to be displayed like in an IE.
Anybody an idea?
Regards Robert

Ok, so an Iframe ist not the best solution right now.
So i did what you said and uploaded the xml content to the ICM cache and generate an URL.
Now i tried to open the URL with an external Window, but inside the new opened IE i can't see anything.
Maybe my coding is not complete?

Accessing cookies in Web Dynpro EP7 (NW07 )

In 6.40 (EP6), we were able to access cookies using the following line of code in web dynpro:
Cookie[] cookieset = TaskBinder.getCurrentTask().getApplicationSession().getWebContextAdapter().getHttpServletRequest().getCookies();
We are upgrading to NW07 and the getWebContextAdapter method is no longer available. Is there a way to access cookies in NW07 through web dynpro java?
Thanks,
Jeff

Hi,
Their no way to access the cookies from Webdynpro, it will be handled by the framework.

ESS Address Required Field Web Dynpro

Hi,
Trying to make a field on the ESS Address screen mandatory. Viewed the Web Dynpro Java Code and updated the label to required - which put the * next to the label on the screen, however I cannot see where the validation check exists.
Do I have to validate the code in web dynpro and if so where or is it a ABAP issue?
Have read in other postings (e.g. Re: ESS Web dynpro for portugal) that the required fields can be updating in the table V_T588MFPROPC. I'm unsure if this is correct as a required field 'City' does not exist in this table, which is a mandatory field. Also what values should I enter and how is the error message format created?
Thanks
Brian

Hi,
Setting the attribute of field as required will only add a * mark in front of it.
If you want to make it mandatory in WebDynpro code then please go through the <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/wd%20java/wd%20tutorials/a%20simple%20input%20form%20with%20message%20and%20error%20service%20support.pdf">following link</a>.
As said by you many of the HR screens field attributes can be configured in SPRO.
SPRO - Personal management - Personal Administration - Customizing UI - Change Screen Modifications.
Hope this helps you.
We can do that setting in backend then thats fine else you can do that in WebDynpro.
