> http://localhost:8080/myApp/PDFClient <- entry servlet and main form http://localhost:8080/myApp/PDFViewer <- servlet loaded in IFrame ok when I click on a linked PDF e. g. <a href="http://localhost:8080/myApp/PDFViewer?file=document-repository/Folder%202/TestDok4.pdf&page=1"; target="viewer-iframe">filename</a> in the PDFClient the PDFViewer should be loaded in the IFrame, which actually is a blank page that just embeds the PDF-File ...process request-parameters and session-vars... if(pdfFile!=null) { output = "<embed src=\""+pdfFile+"#page="+pdfPage +"&toolbar=0&navpanes=0&scrollbar=0&view=Fit\" width= \"550\" height=\"550\">"; } When I call the Viewer with a file 'TestDok1.pdf' which is located in the 'war' file (main directory of the project), it works well, when a pdf-file from a location outside the project directory the generated html looks like it should: <html> <head> <title>PDFViewer</title> </head> <body> <embed src="document-repository/TestDok1.pdf#page=1&toolbar=0&navpanes=0&scrollbar=0&view=Fit" width="550" height="550"> </body> </html> but instead of opening the PDF-File the plugin opens nothing... well at least it reserves the 550x550 pixels for the presentation but all is white nothing is displayed /opt and recursively all contents have rwxrwxrwx... so I would think the access rights should not be the problem... Thx for the quick answer! Ingo
