First - Nice library!

Second - I have users that create Excel files and then later down the road save them with a .csv extension. I know…I know…why they do this is beyond this question. When I use version 0.0.6 on this type of file it reports it as a text/csv. Opening the file in a text editor clearly shows that this is not a csv file. Can you give a reason why it is returning “text/csv” instead of “application/vnd.ms-excel”?

Thanks!

Sorry, been afk due to some job switching Yeah, if you provide me with any patches you guys have arimus AT users.sourceforge.net, I can merge in the changes for folks. I only ask that you give me the okay to dual-license any contributions…I may switch to another license (Apache perhaps) at some point here.

As for licensing, I am currently licensing under the LGPL, which is not a viral license and does not require you to release your code at all. It only requires modifications to jmimemagic itself be opened up to those you distribute to.

jMimeMagic can handle both files and byte[]. Currently streams are not supported, but that wouldn’t be too hard to add.

Renzo,

It shouldn’t be hard to make the change to the code necessary. If you could send me the changes that would be great! I’ll probably be adding this feature soon but can’t guarantee timescale

As for the license issues you should consult with your legal people.

Emmanuel, I’ll look into this when I get a minute. Thanks for posting the issue and solution.

Hi, I’m just looking at jmimeinfo for detecting mime type from blobs as fetched from an own db. Thus I have memory byte arrays, not files. Can I use it anyway ?
Also does the GPL licence imply that we must make all other proprietary application jars available in source ?
Thanks.

for psd files : 2 bugs…
first :
in MagicFile.java function readLine()
byte[] buff = new byte[valueLength];
in.readFully(buff);
line.setValue(buff);

b = in.read();
if (b == ‘&’) {
buff = new byte[valueLength]; // this must be added otherwise value is replaced with mask buffer
in.readFully(buff);
line.setMask(buff);
b = in.read();
}
second:
in Rule.java function Mask()
private void mask(byte[] sample){
for(int i = 0; i

Hello,

jmimeinfo works very well, and it is a good tool, but not for PSD files, fingerprint is not correct and jmimeinfo does not recognize PSD files… How to update mime magic file ?

Thanks Ryan and KewlCat problem has been fixed and new version 0.0.3 is available above.

Wooops… Sorry about that. I _had_ to place the directory named “jmimeinfo/” inside the Eclipse workspace in order to make Ant work as intended. It works !

Same problem here : files get parsed and identified but not closed properly, so any further action on the file is prohibited :-/
I tried to add the two missing “raf.close()” before both returns in Rule.java (lines 133 and 140) but when I recompiled (using Eclipse and the build script) and then tried to use my own version, there was a NullPointerException : net.hedges.mimeinfo.magic.MagicFile.parseMagic(MagicFile.java:51).
Apparently it needs a MIME-Magic that’s not provided in the archive

Could somebody please create and provide a clean jmimeinfo-0.0.3, or a way to make it ?
