Re: Starting off with POI/HSSF

Hi David,

It appears that you are using a version of Java that's too old for the version of POI that you downloaded. (That's what UnsupportedClassVersionError means)

Either use a newer JVM or an older POI jar.

Hi, I've installed poi-3.6-20091214.jar and hssfr4.rpgle dated 10/7/2007 and getting a compatibility error :

Is it the version of JAVA on the i or the wrong version of hssfr4.rpgle? How do I check?

Thanks.
