iTextSharp Error message

Hi,

I am getting the following error message when I try to open a pdf document
retrieved from the database: "PdfReader not opened with owner
password." I think this might me occuring when a document has a copyright
mark on it because my code works OK when the document is not a copyrright pdf
document. What is the best way to ensure that the document is opened without
problem? Relevant portion of the code is given below. List<PdfReader>
documents=newList<PdfReader>( );

 documents.Add( newPdfReader( fileContent1 ) );// fileContent1 and fileContent2
are two files retrieved from the database

documents.Add( newPdfReader( fileContent2 ) );Document doc1=newDocument(
);MemoryStream output=newMemoryStream( );

output.Position=0;PdfWriter writer=PdfWriter.GetInstance( doc1, output );

doc1.Open( );

PdfContentByte cbyte=writer.DirectContent;foreach ( PdfReader pdfReader in
documents )

{

// open the file to be appendedPdfReader reader=newPdfReader( pdfReader );

 

// load each page into the merged documentfor ( int page=1;
page<=reader.NumberOfPages; page++ )

{

doc1.NewPage( );PdfImportedPage importedPage=writer.GetImportedPage( reader,
page );

cbyte.AddTemplate( importedPage, 0, 0 );

}

}

// MERGE CODE END

doc1.Close( );

An odd thought that came to me while we were addressing the other thread -

 Is there a need to save the PDF in the database?  What about saving it on the
server instead and saving the path in the DB?
