When running my chart report I get this error:

**Error filling print... java.math.BigDecimal cannot be cast to java.lang.String ......Print not filled.

The variable I'm using is pulled from an Oracle database and is a BigDecimal data type. In my Value Expression, I'm setting the Value Class Name as java.math.BigDecimal as well. I've tried passing the variable as a string and that doesn't work either.

Does anyone have any thoughts on how I can get past this error?

Hi reggiereg,

I had to face these kind of errors a while ago, i had fixed it with adding blank string to the String variable passing. Somthing like below.

BigDecimal testNum = new BigDecimal("29.87");
String str = testNum + "";
 
Hope this will help, if not provide full jrxml for debugging.
