My code is like this(as specified in tpt handbook):

DocumentViewer viewer = new DocumentViewer();
	        addComponent ( viewer );
	        
	        java.io.File pdfFile = new java.io.File ( "C:/handbook.pdf" );
	        viewer.loadDocument( new PdfDocument( pdfFile ) );
	        addComponent(viewer);

I want urgent solution and want to show with tpt DocumentViewer..
Can someone help me in this regard please..
Remember that i want this solution with "tpt DocumentViewer"..

The problem is your usage of the Document-Viewer-library as you can see here:

java.lang.AbstractMethodError: eu.livotov.tpt.gui.vdv.core.SinglePageDocumentRenderer.generateCell(Lcom/vaadin/ui/Table;Ljava/lang/Object;Ljava/lang/Object;)Ljava/lang/Object;

The method you are calling is declared abstract and has no concrete implementation. Maybe you should ask your question in a "tpt document viewer"-forum as it is not Vaadin-related.
