[Private_Member_52584]

Hi Experts,

I have Created One WebDynpro LocalDevelopament project with two components.One for OnlineInteractiveform and another one for offline interactive form.

I have created same context for both components which i was developed in ALD. When i try to run my onlineInteractive application i got one error in my view.i.e.

Error occurred while creating PDF document. Please contact System Administrator .

Please Help why i am getting this error.

Thanks In advanced.

Which is line #97?

[Private_Member_52584]

Hi

IWDClientUser wduser=WDClientUser.getCurrentUser();// this is the line no 97.

You are getting null pointer exception when retrieving the user name. Try using the last_name or first_name instead.

Regards, Aldo.

Also try this code to get the logged in user Id:

IWDClientUser wdUser;
		try {
			wdUser = WDClientUser.getCurrentUser();
			IUser user = wdUser.getSAPUser();
			if (user != null)
			try {
				  {
				  	IUserAccount[] acct = user.getUserAccounts();
					  if(acct[0] != null)
					  {
						  String strUserid = acct[0].getLogonUid();
					  }
				  }
			} catch (UMException e1) {
				e1.printStackTrace();
			}
		} catch (WDUMException e) {
			e.printStackTrace();
		}

Hi Venkat,

Look like there's might be some problem in your webdynpro code. Can you check your trace to see if anything is coming there or not. Also, below link is a good guide for creating online and offline forms -

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/4fd2d690-0201-0010-de83-b4fa0c93e...

hope it helps..

I suggest you to follow the guide provided by Sen so as to create the form without coding.

Hi,

This is the code i have write in wdDoinit() method in my first project.

public void wdDoInit()

{

//@@begin wdDoInit()

try

String loginuser="";

String userId=new String();

IWDClientUser wduser=WDClientUser.getCurrentUser();

com.sap.security.api.IUser user=wduser.getSAPUser();

if(user!=null)

{

IUserAccount [] acc=user.getUserAccounts();

if(acc[0]!=null)

{

Hi Venkat,

Don't you have any other information to let us figure out what's happening? What you've posted is very generic and can have multiple causes. Perhaps you can tell us a bit more of what you've done or post the complete error.

Regards, Aldo.

[Private_Member_52584]

I have Created One WebDynpro LocalDevelopament project with two components.One for OnlineInteractiveform and another one for offline interactive form.In my project i have created two applications for two components.In the firstcomponent i have created context in the component controller which is same hierarchy in the adobe life cycle designer.later i have write a code in the generetepdf() in the begin others of component controller. The code like this

public boolean generatePDF( )

{

try{

IWDPDFDocumentCreationContext ctx=WDPDFDocumentFactory.getDocumentHandler().getDocumentCreationContext();

ctx.setDynamic(true);

ctx.setTemplate(getTemplate("VTravelAppView_InteractiveForm.xdp"));

ctx.setData(WDInteractiveFormHelper.getContextDataAsStream(wdContext.nodeTravelRequestDetails()));

IWDPDFDocument doc=ctx.execute();

IWDResource pdfDownload = WDResourceFactory.createResource(doc.getPDF(),"Travel Request Form",WDWebResourceType.PDF);

wdContext.currentFileDownloadElement().setPdfSource(pdfDownload);

//wdContext.currentPDFSourceElement().setPDFBinary(doc.getPDF());

}

catch (Exception e)

{

wdComponentAPI.getMessageManager().reportException("Error occurred while creating PDF document. Please contact System Administrator",false);

e.printStackTrace();

return false;

}

return true;

}

private byte[] getTemplate(String fileName) {

FileInputStream fis = null;

byte[] b = null;

try {

File f =

new File(

WDURLGenerator.getResourcePath(

wdComponentAPI.getDeployableObjectPart(),

fileName));

fis = new FileInputStream(f);

b = new byte[(int) f.length()];

fis.read(b);

} catch (Exception e) {

wdComponentAPI.getMessageManager().reportException("Error occurred while reading form template.", false);

e.printStackTrace();

} finally {

try {

if (fis != null)

fis.close();

} catch (IOException e) {

wdComponentAPI.getMessageManager().reportException("Application error occurred in getTemplate.", false);

e.printStackTrace();

}

this generatepdf() called in wdinit() method.

in the view I have Inserted Interactive Form child element and set all the properties.

I have created same context for Second component which i was developed in ALD.And created one application for second component also. When i try to run my onlineInteractive application one i got one error in my view.i.e.

"Error occurred while creating PDF document. Please contact System Administrator ".

This the error message printed in the view.

Please Help why i am getting this error.

Thanks In advanced.
