I replaced the following line of code:
OutputDoc.addPage(page); // ***** test only *****
with these lines:
PDPage BlankPage = new PDPage();
OutputDoc.addPage(BlankPage );
and that worked fine.
However, it does not line me adding pages from another document.
Do I have to do something to the catalog first or . . . ? (I did not see this
in the examples.)
Thanks, Alan

Subject: java.io.IOException: The handle is invalid
What might cause the runtime error: "java.io.IOException: The handle is
invalid" in COSVisitorException?
All I did in my code with the problem object "OutputDoc" was:
PDDocument InputDoc = null;
PDDocument OutputDoc = new PDDocument();
try
{
InputDoc = PDDocument.load( pdfInFile );
. . . . .
List pages = InputDoc.getDocumentCatalog().getAllPages();
Iterator iter = pages.iterator();
while( iter.hasNext() )
{
PDPage page = (PDPage)iter.next();
OutputDoc.addPage(page); // ***** test only *****
. . . . .
}
finally
{
if( InputDoc != null )
{
InputDoc.close();
OutputDoc.save(pdfOutFile);
OutputDoc.close();
}
}
Here is the stack trace, below. Thanks, Alan
