As noted by Nick on the issue, a better alternative is to use
TikaInputStream as it automatically takes care of creating and removing 
the temporary file if needed.


The relevant code within a parse() method should look something like this:

TemporaryFiles tmp = new TemporaryFiles();
try {
TikaInputStream tis = TikaInputStream.get(stream, tmp);
File file = tis.getFile();
...; // process the file
} finally {
tmp.dispose();
}

See the TikaInputStream and TemporaryFiles javadocs for the details.

One of the possible solutions is to create temporary file, pass it to the
citor and delete it after using.


OutputStream out = null;

File tempFile = new File(tempPSTFileName);
try {
out = new FileOutputStream(tempFile);
byte buf[] = new byte[1<<20];
int len;
while ((len = inputStream.read(buf)) > 0) {
out.write(buf, 0, len);
}

} catch (IOException e) {

} finally {
out.flush();
out.close();
if(inputStream != null && inputStream.available() > 0)
inputStream.close();
}
}

//delete after
tempFile.delete();
-or-
tempFile.deleteOnExit();


BR,
Oleg
