Hi,

byte[] pdfContent = wdContext.currentChnnode().getPdf_Data();

String pdfFileName = Constants.PdfName;

WDDeployableObjectPart objPart=wdThis.wdGetAPI().getComponent().getDeployableObjectPart();

IWDCachedWebResource pdfResource= WDWebResource.getPublicCachedWebResource(pdfContent,WDWebResourceType.PDF,WDScopeType.APPLICATION_SCOPE,objPart,Constants.page1);

try

{

wdComponentAPI.getWindowManager().createNonModalExternalWindow(pdfResource.getURL(),pdfFileName).show();

}

catch (WDURLException e)

{

wdComponentAPI.getMessageManager().reportException(e.getMessage(),false);

}

Hi,

Code is fine Mr.Sathish... Check the datatype of attribute Pdf_data, if binary or not.

and change this statement as I worked

wdComponentAPI.getWindowManager().createNonModalExternalWindow(pdfResource.getURL(0),pdfFileName).show();

Hi,

Sorry for it... My code is this one

data=wdContext.currentcontextElement().getPdfsource();

IWDResource resource = WDResourceFactory.createCachedResource(data , "PDF Report", WDWebResourceType.PDF);

IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(resource.getUrl(0), "PDF Report");

window.show();

Try this way
