File does not begin with %PDF- error

Hi All,

We have a scenario in which a R/3 report has to be displayed in PDF format, at front end, with the help of a webdynpro application. The data is being sent through a RFC function module. The report was working fine, but due to the upgrade of backend from 4.6C to ECC 6.0, the function module to convert data to pdf format in R/3 was not working propely.

To fix this error, we had to add a parameter of type 'Blob' in the function module, which can send the data in binary format.

I have made reqired changes in the webdynpro applicaiton to use this parameter, but it is still giving me the error " File does not begin with %PDF- "

Please help to resolve this issue.

Thanks for your time & help!

Regards,

Anupama

Hi please find the code that i have added :

Hi Deepak,

thanks a lot for replying!

This is the piece of code that i haev added in component controller of the application :

I am trying to fetch the data into an array of type byte. Pdf1 is the export node from R/3.

		long filelen = wdContext.nodePdf1().size();		
		byte[] temp1 = new byte[(int)filelen];

for (int i = 0; i < wdContext.nodePdf1().size(); i++) {
			temp1 = wdContext.nodePdf1().getPdf1ElementAt(i).getContent();
		}

IWDResource resource = WDResourceFactory.createCachedResource(temp1, "Job Description" + position + System.currentTimeMillis()+".pdf", WDWebResourceType.PDF);
		
		wdContext.currentContextElement().setRolePurposeURL(resource.getUrl(WDFileDownloadBehaviour.AUTO.ordinal()));
		wdComponentAPI.getMessageManager().reportSuccess("url name ....."+wdContext.currentContextElement().getRolePurposeURL());
		wdContext.currentContextElement().setRolePurposeVisible(WDVisibility.VISIBLE);

For more clarifications please come back.

HI,

Instead of 'temp1' in the line

IWDResource resource = WDResourceFactory.createCachedResource(temp1, "Job Description" + position + System.currentTimeMillis()+".pdf", WDWebResourceType.PDF);

Try to use 'wdContext.nodePdf1().getPdf1ElementAt(i).getContent().getBytes();.

Use this sample code.. This will open an html file

String html="<html>Test<html>";

IWDResource res=WDResourceFactory.createResource(html.getBytes(),"HTML File",WDWebResourceType.HTML);

IWDWindow win = wdComponentAPI.getWindowManager().createNonModalExternalWindow(res.getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal()),"Title");

win.open();

Best Wishes

HI Deepak,

The value for temp1 = [B@1dc4d3f (for a specific user) temp1 length = 255

temp1 is a byte array, in which i am taking the value fetched from R/3 FM sent in the form of Blob datatype.

Value supposed to be in temp1 will be different for different users.

The value of resource is = 

xyz.com/wd~rps/MyRolePurpose/~wd_key22_1274071720178/Job+Description600223571274071720178.pdf?sap-wd-download=1&sap-wd-cltwndid=74f1f3ce616f11dfb2d20050568348a8&sap-wd-secure-id=74f1f3d0616f11dfc3d80050568348a85609101389&sap-wd-appwndid=74f1f3cf616f11dfb3fb0050568348a8&sap-wd-norefresh=X

The value of url is = 

/xyz.com/wd~rps/MyRolePurpose/~wd_key22_1274071720178/Job+Description600223571274071720178.pdf?sap-wd-download=1&sap-wd-cltwndid=74f1f3ce616f11dfb2d20050568348a8&sap-wd-secure-id=74f1f3d0616f11dfc3d80050568348a85609101389&sap-wd-appwndid=74f1f3cf616f11dfb3fb0050568348a8&sap-wd-norefresh=X

Is the data sent from R/3 is encoded ?. The lenght of the array is displayed at 255, but i could see only 9 characters in the output.

Thanks & Regards,

Anupama

Hi All,

This issue is fixed now. Instead of using Blob, the data from R/3 backend was send to webdynpro application in form of XString.

Webdynpro application was able to recognize data & PDF is displayed correctly!

I thank you all for your time and judicious help!
