The problem seems to be that you cannot specify the ooxml related jar
files on bootclasspath

Hi,
I am getting an exception when creating an XSSFWorkbook object using
the constructor - new XSSFWorkbook();
It must have something to do with the way I am running it. Either
because I am using a Thread. Or maybe my classpath. I am using
eclipse, and have the below jar files in 'Bootstrap Entries' section
poi-3.5-beta5-20090219.jar
poi-ooxml-3.5-beta5-20090219.jar
xmlbeans-2.3.0.jar
ooxml-schemas-1.0.jar
dom4j-1.6.1.jar
log4j-1.2.13.jar
