Web Dynpro Java Application for Handheld Device

Hi everybody,
I have been reading some documentation about what is the best option to create an application for handheld device. So this is my landscape. I have SAP Netweaver 7.4 SR1 AS ABAP, and Java instance. So, I want to know whether is possible to create a normal web dynpro java application and then visualize this application on Browser of handheld device. That's all that I have to do? I read that exist another solution Developing mobile application for handhelds. By other side a need to know how to is the integration of this device with this application if exist. This application is going to consume data from SAP Backend system, so I just have to create JCO's for connect this application to this system, right?
Please, can you help me with that.
Best Regards.

Hi Deepti,,
Refer to the following thread which says that you must retrieve the data from the CRM backend system using standard BAPI's or customer Remote enabled function modules (socalled RFC's) and to access the backend system you will have to set up an RFC connection with CRM system.
Regarding web dynpro and CRM

HTTP form post from Web Dynpro Java Application without opening new window

Hi Experts,
We are trying to submit form data to an external URL from Web Dynpro Java application. We are achieving this with the following piece of code.
try
   strPrintContent="<html>"+
     "<head>"+
     "<script type=\"text/javascript\">"+
     "function myfunc () "+
     "{"+
     "var frm = document.getElementById(\"paymentForm\");"+
     "frm.submit();"+
     "}"+
     "</script>"+
     "</head>"+
     "<body onLoad=myfunc()>"+
     "<form id=paymentForm method=post action=\""+merchantURLPart+"\">"+
     "<INPUT type=hidden name=username value="+userName+">"+
     "<INPUT type=hidden name=pass value="+passWord+">"+
     "<INPUT type=hidden name=senderid value="+senderID+">"+
     "<INPUT type=hidden name=dest_mobileno value="+mobile+">"+
     "<INPUT type=hidden name=message value='"+msg+"'>"+
     "<INPUT type=hidden name=response value="+response+">"+
     "</form>"+
     "</body>"+
     "</html>";
IWDWebResource webResource = WDWebResource.getWebResource(strPrintContent.getBytes(),WDWebResourceType.HTML);
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(webResource.getAbsoluteURL(),"WBSEDCL");
window.show();
catch(Exception e)
wdComponentAPI.getMessageManager().reportException("Error : "+e.toString(),false);
But it opens another window. We dont need that. We have to stay on the same window. Please suggest what can be done.

Hi,
You can create a HTML file with the request post parameters and the external URL something like this:
public java.lang.String GetRedirecturl( )
// External URL
String html = "<html><head></head><body onload=\"load()\"> " +
"<form id=\"form1\" action=\"https://www.abc.com/xyz.jsp\" method=\"POST\">" +
// Post Parameters
"<INPUT TYPE=\"HIDDEN\" NAME=\"Param1\"VALUE=\""+Param1Value+"\">"+
"<input name=\"sap-wd-resumeurl\" type=\"hidden\"/>" +
"</form> " +
"" +
"<script>" +
"function load(){" +
"var loc = window.location.search.substring(1);" +
"var queryString = loc.split(\"sap-wd-resumeurl=\");" +
"if(queryString.length > 0)" +
"{" +
"var resumeURL = queryString[1].split(\"&\");" +
"if(resumeURL.length >= 0)" +
"{" +
" document.forms['form1'].elements['sap-wd-resumeurl'].value= unescape(resumeURL[0])" +
"}" +
"}" +
"document.getElementById('form1').submit();" +
"}" +
"</script>" +
"</body> </html>";
String redirectUrl = "";
byte[] byteArrayHtmlData = null;
try {
byteArrayHtmlData = html.getBytes("UTF-8");
} catch (UnsupportedEncodingException e) {
wdComponentAPI.getMessageManager().reportException("Internal error occurred. Please try after some time",true);
IWDResource htmlResource = WDResourceFactory.createCachedResource(new ByteArrayInputStream(byteArrayHtmlData), "Redirect.html", WDWebResourceType.HTML, true);
redirectUrl = htmlResource.getUrl(WDFileDownloadBehaviour.AUTO.ordinal());
return redirectUrl;
Hope this will be helpful.

Problem: Changing Language for Web Dynpro Java within NW Portal (i18n)

Hi Experts out there,
I hope all you had a nice Christmas and a big New Years Eve :)!!!
i got a challenge for you about WD Java and internationalization (i18n)
Here is the scenario:
We are using a SAP NetWeaver Portal 7.0 and my task is to implement some smaller Web Dynpro Applications.
These Applications must be i18n conform, so i just created (according to the corresponding WD Java tutorial) some ".xlf" files.
Okay...Everything is working fine. The user can log at the portal and the application is displayed in his language, which is "english" or "german". (the application is just a simple form)
So far so good...Now here comes the point where it's getting tricky...
When the user wants to change his assigned language (of the portal user) he can use the "personalize" button in the Masthead (-> change portal language). All the portal content should now be displayed in his new chosen language.
For example the user is logged into the portal with "german" as portal language and now changes his languages settings into "english". After this everything in the portal (navigation, portal iViews ) is displayed in the changed language (from english into german) ...
BUT: my Web Dynpro Java Application stays as the original languages setting was. That means the whole portal is now english, but my WD Java Appl. stays german .
Only if the user logs of and logs in again, the WD Java Appl. is displayed in the corresponding portal language...
VERY Strange?!?!
Can anybody give me a hint how to solve this problem?
I guess i have to re-initiate the Web Dynpro Application some how ...(like killing the application and restarting it ...) but is just a "weak guess"...
Any Help / Hint is more than welcome !!!
Cheers
Stefan

Hi Stefan,
This correct see SAP Note [947081|https://service.sap.com/sap/support/notes/947081]
If the locale for the Web Dynpro iView is changed in the portal (through portal personalization), this is not reflected in the running login session. The user needs to logoff and login again, in order to see the locale change in the Web Dynpro iView.

" APPLICATION NOT FOUND" while deploying Web dynpro java Application

Hi, I am getting a message that "application not found " While deploying the web dynpro java application .......... please give me a solution for this .

Hi Ram,
This error comes generally when your webdynpro project does not have an application. To create an application in your webdynpro project follow the underlying steps:
<Project>->WebDynpro->Applications ---> right click and create New Application.
Follow the steps to create the application.
Now if you create archive and deploy, it will not give you the error again.

Hi,
Since the exception says "Are all referenced components deployed and available on the engine?"
Check wether any DC is used as a used DC in the webdynpro component which you are deploying.
If any used DC is available try to deploy that DC in the server and then deploy ur webdynpro application.
If all reference DC's are avialable in server, still if you get this error try to rename the component and reload+rebuild the project and deploy it.
Hope this helps you...

Saleem Mohammad.

Deploying web dynpro java application successfully but not working

Hi all,
I have a web dynpro java application. When I deployed in my local portal (7.10 SP6) it is working fine. But when I deployed in another portal (7.10 SP2) it is not working totally. In system default trace I saw below exception:
Failed to create deployable object 'sap.com/a1sbicbc~unv' since it is not a Web Dynpro object.
It seems that the web dynpro application was not deployed anymore, but in deployment UI I can see the package was deployed without any errors.
In this situation, is there any other portal/java engine configuration which may prevent the web dynpro application being deployed? For example deployment or security policy, etc?
Looking forward for replies.
B.R.

Hi,
Try to undeploy the application from the server
Then deploy it

Use loadrunner to test Web Dynpro Java Application

Hi Gurus,
I'm using Loadrunner 11.0 to do load test to Web Dynpro Java Application. At first, I used web(http/html) protocel script, and I could record the whole business process successfully. But the script seems very hard to understand. For example, the following script is so complex.
After this, I tried 'SAP Click and Script'. At this time, loadrunner only record my logon action, while my business operation was not recorded in the script.
"Body=sap-ext-sid=nYCksrUa3nHq2NIwTPpTKg--LpNoVBU_d2sS7nCHLaG*qQ--&sap-wd-cltwndid=WID1411644055966&sap-wd-norefresh=X&sap-wd-secure-id=kNh-egwklSanOHIGRb7-eA%3D%3D&SAPEVENTQUEUE="

Hi Zhihua,
First delete all the cookies from your browser.
Close all the internet sessions which are opened in your system. During your script recording
Open only 1 session which you will be recording for java script.
The above mention log is the cookies from the internet explorer.
its of no use for the script you can even delete from the script.

Problem Web Dynpro Java applications using JasperReports

Hello all,
We have followed the footsteps of these blogs but we can not make it work.

Part II --> Part-II: Print Web Dynpro Java applications using JasperReports
Part III --> Part-III: Print Web Dynpro Java applications using JasperReports
Details system: 7.02 SP3
We believe that the problem is in the library, because it finds them.
1) We created project as a DC external library with *.jars
2) Public part DC external library.
3) Add public part of DC Library into new project DC WebDynpro Java.
4) Development Component -> Build is OK
5) Development Component -> Deploy is OK
6) Test app ERROR.
When we run the application shows the error:

Hello John,
Thanks for the link. We have performed the steps in this blog:
1) Create DC Project "External Library" with name js/jars:
- Add *.jars in folder Libraries.[Screenshot Libraries|http://img846.imageshack.us/img846/8395/jsjars.jpg]
- Add archives (*.jar) to public part with name ExternalLib. Which option to choose?
a- Provides an API for developing/compiling other DCs (Option chosen)
b- Can be packaged into other build results (eg SDAs)
- Development Component -> Build
Step 1 is OK.
2) Create "J2EE Server Component / Library" DC with name js/lib:
- Add Used DC -> public part project ExternalLibrary -> "ExternalLib"
- Specify both build time and run-time dependency here and strong.
- Generated SDA file in <var>gen/default/deploy</var> How do we check that it contains <var>js.jar</var>?
- folder gen/default/plublic/defLib/lib/java then you meet *.jars files again. is OK.
- Development Component -> Deploy.
- Go to Visual Administrator. We found the library js/lib, but has no associated *. jar. It is the problem.[Screenshot Visual Administrator|http://img542.imageshack.us/img542/5537/visualadminlib.jpg]
3) Create "WebDynpro" DC with name pdf_jasper
- Add used DC (defLib) to WebDynpro DC with option "Build time".
- WebDynpro References -> Library references --> add <var>jslib
- Deploy
- Run error: java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

Transport Web Dynpro Java applications on 7.4

Hi Experts
We have couple of web dynpro java applications running on DEV EP 7.4 system. Now we need to move them to Test/Prod. What are the options to move these? Please note we do not use NWDI, so transport thru NWDI is ruled out.
One option is to deploy these applications thru NWDS, but we would like to avoid it if possible.
Are there any other options for transport?
Thank you
Aakash

Thanks Jun
Any other option apart from Telnet?
