Errors with CFSpreadsheet

We had that error as well, and found that we had more than one version of POI lurking in other files.

Try this code to find where the POI calls are coming from and remove any old versions:

<cfset poi = createObject("java", "org.apache.poi.Version")/>

<cfoutput>#poi.getVersion()#</cfoutput>

<cfdump var = "#poi#">

<cfset WorkBook = CreateObject(

                "java",

                "org.apache.poi.hssf.usermodel.HSSFWorkbook"

                ).Init()>

<cfdump var = "#WorkBook#">

<cfset loader = WorkBook.class.getClassLoader()>

<cfdump var = "#loader#">

<cfset res = loader.getResource("org/apache/poi/hssf/usermodel/HSSFWorkbook.class")>

<cfoutput>#res.getPath()#</cfoutput>

<cfset poixml = createObject("java", "org.apache.poi.POIXMLDocument")>

<cfdump var = "#poixml#">
