Thank you. I think the difference is that my local environment on Tomcat is using the Oracle JVM, while the environment where this is an issue is using the IBM JVM. So the zip implementation must be different.
I will go ahead an open up a bug ticket.

If I create a ³corrupt² excel, unzip it, and then zip it back up (on my mac using zip command), the resulting zip file opens without issue. If a colleague on Windows generates the same excel, and does the same probably using windup, the corruption remains. Please check if you see a difference with zipinfo: http://www.info-zip.org/mans/zipinfo.html See below [1] - for your "Results (2).xlsx". I think there was something with the compression method, i.e. not all compression methods might be supported - also defN = "deflate normal" sound like a default compression. IIRC there's also a file in our test-corpus with some strange compression method, which poi can't open. Hmm, for some reason my attached files did not make it into the thread. Is there a UI where I can attach them? Just open a ticket in the bugzilla: https://bz.apache.org/bugzilla/enter_bug.cgi?product=POI&component=XSSF Andi [1] $ zipinfo Results2.xlsx Archive: Results2.xlsx Zip file size: 6744 bytes, number of entries: 11 -rw---- 2.0 fat 596 bl defN 17-Jul-06 10:02 _rels/.rels -rw---- 2.0 fat 1195 bl defN 17-Jul-06 10:02 [Content_Types].xml -rw---- 2.0 fat 184 bl defN 17-Jul-06 10:02 docProps/app.xml -rw---- 2.0 fat 441 bl defN 17-Jul-06 10:02 docProps/core.xml -rw---- 2.0 fat 131 bl defN 17-Jul-06 10:02 xl/drawings/drawing1.xml -rw---- 2.0 fat 138 bl defN 17-Jul-06 10:02 xl/sharedStrings.xml -rw---- 2.0 fat 3601 bl defN 17-Jul-06 10:02 xl/styles.xml -rw---- 2.0 fat 350 bl defN 17-Jul-06 10:02 xl/workbook.xml -rw---- 2.0 fat 574 bl defN 17-Jul-06 10:02 xl/_rels/workbook.xml.rels -rw---- 2.0 fat 22610 bl defN 17-Jul-06 10:02 xl/worksheets/sheet1.xml -rw---- 2.0 fat 303 bl defN 17-Jul-06 10:02 xl/worksheets/_rels/sheet1.xml.rels 11 files, 30123 bytes uncompressed, 5226 bytes compressed: 82.7% ________________________________ DISCLAIMER: E-mails and attachments from Bamboo Rose, LLC are confidential.
