Rober,

As Andy says ask on the list.

In your Tomcat startup on the unix server you need to be sure to set the following property -

 -Djava.awt.headless=true

Do that and all should be good.

If you notice slight differences in widths between windows and unix that may be due to the fact that autoSizeColumn uses fonts to do its magic. (Which is why it needs the "graphic environment") So, then you might want to install fonts into /usr/java/jre/lib/fonts/ on the unix box. If you get stuck with that then you can ask again - Yegor can explain the exact rules.

Regards,
Dave

Summary: autoSizeColumn. Exception in non graphical environment
           Product: POI
           Version: 3.0-dev
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HSSF
        AssignedTo: poi-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]


I developed a webapp that generates excel files. Development environment is Tomcat server under Windows XP. Production server is a Unix machine with no
graphical environment.

autoSizeColumn method, from HSSFSheet class, works ok in windows, but throws an exception in unix environment. The lack of graphical environment seems to be the
reason.
