Jar file in Web Dynpro Java Application!

Hi All:
I needed a Jar file in my WDJ App.
I am using SP16.
Can someone provide ideas/instructions on how to do this?
Thanks in Advance!

Create an external library DC, and stick the jar file into the libraries folder. Create a public part of type compilation, and a public part of type assembly. Add the jar file to both public parts. Specify a compilation DC dependancy between the WD application and this DC. That will solve your compilation problems.
You also have to create a deployable DC, so you can get the jar file onto the server. Create a J2EE library DC, and create an assembly usage dependancy to the external library DC. Build the library DC, and the resulting ear file should contain the jar file. Deploy the library DC to the server.
Lastly, you'll also need to create a library reference between the WD application and the deployed library so the class loader can find the library at runtime. That's done via project properties / Web Dynpro References / Library References. Create a reference, and fill in the name of the J2EE library. If you're unsure of the name, use the Visual Administrator to inspect all the libraries on the server - find your library, click on it, and look at the name in the right-hand panel - that's the name you need to use.
Hope that helps.
I also hope I got everything right

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 I --> Part-I: Print Web Dynpro Java applications using JasperReports
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:
The initial exception that caused the request to fail, was:
   java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

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

Deploying problem of web dynpro java application

Hi,
I have a web dynpro java application with no problem about deploying.

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...

File Visibility in uploading the file using web DynPro java

hello,
i have gone through the tutorial " uploading & downloading the file using web DynPro java".
the upload functionalty is working fine. but i need to know thw path where these files are getting uploaded ??
Waiting for the reply..
Regards,
Viren Gupta

Hi Viren,
Are you are refering to the below tutorial for upload and download:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b0e10426-77ca-2910-7eb5-d7d8982cb83f?QuickLink=index&overridelayout=true
If yes, then answer is that the file is stored in the context of the application only as "com.sap.ide.webdynpro.uielement-definitions.Resource" object. Please read through the tutorial to understand the full process.
WD doesn't really upload to server automatically unless there is any explicit code written. All it does is to store the file in a temp context which you can access and write your own code to store it in a particular location.

Mahesh

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.

Anurag

" 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.

Reading contents of uploaded excel file in web dynpro java

Hi All.
I am aware how to provide facility to upload files in web dynpro java. But my requirement is that on uploading a particular file (for eg. an excel file having 10 columns), I need to read the contents of that file and store it in a table in R/3.Can anyone suggest a way how I can read the contents of the uploaded file?
Thanks and Regards,
Saurabh.

Hi.
I am having the following requirement : I have a FileUpload UI element where user clicks Browse button, selects a file from the local system and presses a Upload button. Upon pressing Upload, the name of the selected file and the contents of the file should be shown.
In the View context, I have two value attributes: FileName of type String and FileResource of type binary.
This is the code that I have in the Upload button action handler :
public void onActionUpload(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionUpload(ServerEvent)
    IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(
             IPrivateReadExcelView.IContextElement.FILE_RESOURCE);
    IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.
             getModifiableSimpleType();
    IPrivateReadExcelView.IContextElement element = wdContext.createContextElement();
    String fname = binaryType.getFileName();
    wdComponentAPI.getMessageManager().reportSuccess("File selected - "+fname); //Statement 1
     try {
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    // Statement 2
          InputStream in = new FileInputStream(fname);
          HSSFWorkbook wb = new HSSFWorkbook(in);
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    //Statement 3
          int sheetsNo = wb.getNumberOfSheets();
          for (int i=0;i<sheetsNo;i++) {
               HSSFSheet sheet = wb.getSheetAt(i);
               Iterator rowsNo = sheet.rowIterator();
               while(rowsNo.hasNext()) {
                    HSSFRow rows = (HSSFRow)rowsNo.next();
                    Iterator colsNo = rows.cellIterator();
                    while(colsNo.hasNext()) {
                         HSSFCell cell = (HSSFCell)colsNo.next();
                         wdComponentAPI.getMessageManager().reportSuccess("File uploaded" +
                              "successfully");
                         if(cell.getCellType()==1) {
                              wdComponentAPI.getMessageManager().reportSuccess("00000"+
                                   cell.getStringCellValue());
                         else if(cell.getCellType()==0) {
                              String str=""+cell.getNumericCellValue();
                              wdComponentAPI.getMessageManager().reportSuccess("11111"+str);
     catch(Exception e) { wdComponentAPI.getMessageManager().raisePendingException();
    //@@end
On pressing Upload button, name of selected file is being shown(Statement 1). I am also getting Statement 2 in the output. However I am not getting Statement 3 onwards.
Where am I going wrong? Can anyone shed some light on this?

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

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

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.

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?

Hi All,
I don't know if I am asking too much, but I have a requirement as below

Access Web Dynpro Java application through direct URL

Hi Guys,
we have a requirement that there is a link in web dynpro abap screen, click on it will open a new ie window running web dynpro java application, so what i did is i have given direct url link for that web dynpro java application:
as this:
https://servername:50001/webdynpro/dispatcher/sap.com/ess~lea/TeamView
but after i clicked on this url, it pop up 1 window, after i entered id & passoword, it is showing this wd java appl, but there is 1 grey image on top of the view & "welcome xxxx"; below that is the actual view from wd java.
the layout is :
grey image----
welcome xxxxxxxx
Teamview
actual ivew
how to remove the grey image & the "welcome xxx"? it looks like masthead but we dun need it.
thanks

Hi Feng,
Actually what you are seeing using the application URL and after giving the credentials on Portal is a portal screen which carries the theme as well. Therefore, you will be able to see the masthead with header and Portal User Name. So, use the URL generated by preview of a web dynpro iView in your component to avoid the masthead.
