Question

I’m currently writing a program in Java to extract metadata from multiple document type.
At the moment I’m trying to extract metadata from .vsd files using Apache Tika.
I previously tried using Apache POI directly, but the fact is it’s very hard to find any documentation on this unusued part of the library, so I decided to go with Tika.

Ok, so here is the code sample I’m crashing on ( crash at line : 7) :

        ParseContext context = new ParseContext();
        Metadata metadata = new Metadata();
        WriteOutContentHandler handler = new WriteOutContentHandler(10 * 1024 * 1024);
try {
            FileInputStream fis = new FileInputStream(fileName);
            OfficeParser officeParser = new OfficeParser();
            officeParser.parse(fis, handler, metadata, context);
            String[] metadataNames = metadata.names();

            // Display all metadata
            for (String name : metadataNames) {
                System.out.println(name + ": " + metadata.get(name));
            }
        } catch (FileNotFoundException E) {
            System.out.println("No such files : " + fileName);
        }

And here is the stacktrace :

I’m pretty rusty in Java, so I hope my question is not too obvious to answer to.

Thank you.

So the problem was a bad vsd file.
