.docx internal zip format invalid

[cel22262]

I have been sucessfully using the "XmlJasperInterface" code (originally written by Jonas Schwertfeger) to embed Jasper reports in my Rails application. I have recently tried to expand this code to include .docx, .xlsx, and .pptx exporters. The code compiles OK and executes with no errors generating a .docx file. Upon initial inspection of the output file, I see" PK..." markers as well as the various .xml sections, however the file fails to open with MS word or OO writer. When I try to unARK (unzip) the file I get the following message:
[@Rift tmp]# /usr/bin/zipinfo -lT /tmp/Medical_Chronology10099233329.docx

The other exporters work fine (PDF, RTF, etc....)

The attachments include the BROKEN.DOCX, the compile script and directory of the LIB directory(classpath)
Any ideas/suggestion? BTW My OS environment is Linux (Mandriva 2010.2)

Further investigation indicated the overall content of the file is correct. But I receive this nessage when I try to unzip the file:

[....]# unzip x.docx
Archive:  x.docx
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of x.docx or
        x.docx.zip, and cannot find x.docx.ZIP, period.

 

I get the same error message on an .ODT file. If I open the .ODT with OpenOffice I get a message that the file is corrupted, but OO writer is able to repair it (similar message in MS Word with a .DOCX file).....

It would appear the the exporter is not properly closing the file and/or writing the correct trailer (central-directory)....
