Hello,

I’m doing a test with the ASPOSE.PDF package and I’m having some problems when execute this line “Document doc = new Document(“C:/@TEMP/input.pdf”)”, the following message appears:

In my controller i use this imports
import com.aspose.pdf.Document;
import com.aspose.pdf.HorizontalAlignment;
import com.aspose.pdf.VerticalAlignment;
import com.aspose.pdf.WatermarkArtifact;
import com.aspose.pdf.facades.EncodingType;
import com.aspose.pdf.facades.FontStyle;
import com.aspose.pdf.facades.FormattedText;

Method accessed on button click
public void gerarMarcaDagua(){
// Carregar documento PDF
Document doc = new Document(“C:/@TEMP/input.pdf”);

	// Criar um texto formatado
	FormattedText formattedText = new FormattedText("Confidential Document", java.awt.Color.RED, FontStyle.Courier, EncodingType.Identity_h, true, 40.0F);

	// Criar artefato de marca d'água e definir suas propriedades
	WatermarkArtifact artifact = new WatermarkArtifact();        
	artifact.setText(formattedText);        
	artifact.setArtifactHorizontalAlignment (HorizontalAlignment.Center);
	artifact.setArtifactVerticalAlignment (VerticalAlignment.Center);
	artifact.setRotation (25);
	artifact.setOpacity (0.5);
	artifact.setBackground (false);

	// Adicionar marca d'água à primeira página do PDF
	doc.getPages().get_Item(1).getArtifacts().add(artifact);
	
	// Salvar documento PDF com marca d'água
	doc.save("C:/@TEMP/watermark.pdf");		

	doc.close();
}

@PauloRcg

We apologize for the delayed response. The error is generic and it can be caused due to different factors. Please make sure that JAR is properly referenced and file name or Class Names are not similar to the name of any API Classes. Also, folder structure should be cleaned and sorted in the project. Please share a sample console application with us in case issue still persists. We will test the scenario in our environment and address it accordingly.
