java.lang.NegativeArraySizeException
HI,
I am using
poi-3.0.1-FINAL-20070705.jar, poi-contrib-3.0.1-FINAL-20070705.jar,
poi-scratchpad-3.0.1-FINAL-20070705.jar jars for reading content of
documents..
I am getting below exception when I try to read password protected document.
java.lang.NegativeArraySizeException

same exception
Please do the needful.
Thanking You.

Your document isn't an office open xml file. It looks to me like it was
generated by a beta version of office 2007, from back before the
specification was finished, and before office implemented it properly.
Try opening it and saving it again in excel, with any luck it'll be
upgraded to a real ooxml file

You'll want to read the documentation for poi 3.5, you need to use a
slightly different class for the ooxml files (same interfaces though), or
there's a handy org.apache.poi.extractor.ExtractorFactory which'll build
the right text extractor for you

If you give an OOXML file to POIFSFileSystem, you'll get that exception!
Just give ExtractorFactory the file or input stream, and it'll do the
rest.
WordExtractor DocExt = (WordExtractor)we.createExtractor(file);
fReader = new CharArrayReader(DocExt.getText().toCharArray());

Sounds good. Give me a shout if I should do any of the paperwork / filing
with my PMC chair hat on

Yeah. That is a lot easier. In the past getting it wrong involved
potential jail time. That sounded like a bad idea to me. :-)
This "One may not, however, knowlingly[sic] export source code to a
terrorist country, although source code may be posted on the WWW for
downloading without the poster having to check whether it is
downloaded from a terrorist country." is a key change (if true).
So it looks to me like it is in the clear. I'll check my old laptops
for the prototype code I wrote that semi-implements this. It is
against a pretty out of date version (~1.x-ish) but might be relevant
at least for the binary formats.

It's fairly easy for apache projects to do crypto stuff now. We have to
record in the right place that we're doing it, fire off a form letter to
the US government, update the readme and the website with some boiler
plate text and we're done. It's all on this handy page:

http://rechten.uvt.nl/koops/cryptolaw/cls2.htm#us gives kind of a
history of this. Because Apache servers are in the US, US law is
supreme here, but individuals may have other issues in their home
countries. It looks like we're now in the clear to implement this,
but IANAL.

To be clear we didn't include Password protection not because we
didn't figure out how to reverse engineer (I did) it but because I
didn't want to navigate the legal issues. Meaning there is a whole
set of US and International regimes involved in encryption. At the
time these were ever worse than they are now. I didn't want to figure
it all out just to provide "fool me, lie to me" security.

Reading password protected files is not supported. The documentation has
finally been released by Microsoft (back in June), so if someone wanted to
add support it wouldn't be impossible. You'd probably be looking at
several weeks of coding per file format

You want POI 3.5 for ooxml support, including .docx files. It's in beta,
or in a different svn branch

We added detection of password protected word documents to svn trunk about
a week ago. If you try with a recent nightly build / svn checkout, you'll
get the much more helpful org.apache.poi.EncryptedDocumentException
