I am attempting to extend Scott's HSSF service program to include
support for formula evaluation.

I have defined an object call HSSFFormulaEvaluator

d HSSFFormulaEvaluator...
d                 s               o   Class(*JAVA:
d                                      'org.apache.poi.hssf.usermodel.-
d                                     HSSFFormulaEvaluator')

I have defined a new for creating a formula evaluator.

*-----------------------------------------------------------------
* new_HSSFFormulaEvaluator
* Create a new HSSF (Excel) FormulaEvaluator
*
* Returns the new HSSFWorkbook object
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
d new_HSSFFormulaEvaluator...
d PR Like(HSSFFormulaEvaluator)
d ExtProc(*JAVA :
d 'org.apache.poi.hssf.usermodel.-
d HSSFFormulaEvaluator' :
d *CONSTRUCTOR)
d PR_HSSFWorkbook...
d Like(HSSFWorkbook)
d Const

When I run this piece of code I get back a valid object.

// Create a formula evaluator to evaulate a cell.
FormulaEvaluator = new_HSSFFormulaEvaluator(Book);

Now I need to evaluate the cell. Here is my definition for the evaluate.

*-----------------------------------------------------------------
* HSSFFormulaEvalulator_Evalulate
* Function evalulates a cell. If cell contains a formula, formula
* is evaluated and value record.
* peCell = Take a Cell object as input.
*
* returns CellValue object.
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
d HSSFFormulaEvaluator_Evaluate...
d pr Like(HSSFCellValue)
d ExtProc(*JAVA :
d 'org.apache.poi.hssf.usermodel.-
d HSSFFormulaEvaluator' :
d 'evaluate' )
d PR_HSSFCell...
d Like(HSSFCell)
d Const

But when I run the evalulate I get a Java exception saying there is no
such method.

CellValue = HSSFFormulaEvaluator_Evaluate(InFormulaEvaluator:

Cell );

Cause . . . . . : RPG procedure GETCELL in program ALANC/T2HSSF received
Java exception "java.lang.NoSuchMethodError:
org/apache/poi/hssf/usermodel/HSSFFormulaEvaluator.evaluate(Lorg/apache"
when calling method "evaluate" with signature
"(Lorg.apache.poi.hssf.usermodel.HSSFCell;)Lorg.apache.poi.ss.usermodel.Cell
Value;" in class "org.apache.poi.hssf.usermodel.HSSFFormulaEvaluator".

What am I doing wrong? I double checked the documenation.

Thanks for any help.
