--- Comment #6 from ppggff <pgf...@gmail.com> --- It seems jdk after 1.7b55 supports zip64 in 2009. (https://blogs.oracle.com/xuemingshen/entry/zip64_support_for_4g_zipfile) But it didn't help this problem. xlsx file generated by POI with newest jdk (1.7.0_21) didn't work. The result xlsx file can be uncompress by 7zip successfully. And then I built a new zip file with 7zip, the new zip file worked with office. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
