Jasper string functions method undefined error

Using Jasper Reports 5.6.1. Added some text functions to a previously working text field jrxml (just want to truncate if longer than 75 chars). Works in iReport Studio, but not in Java.

<textFieldExpression><![CDATA[IF(LEN($F{AccountName})<75,$F{AccountName},LEFT($F{AccountName},75)+"...")]]></textFieldExpression>

Error message:

I checked packages in jasperreports-5.6.1.jar file, includes functions package. Exhaustive web search turned up nothing. What could it be?

I have a similar error message. Where you able to resolve this? Works fine in Jaspersoft Studio 6.0.1, but throws this when compiling w/ Java:

The method IF(boolean, BigDecimal, BigDecimal) is undefined for the type Blank_A4_1_1423164610392_674232

Update: I was able to solve this by including the functions jar on my classpath. See that if that works for you. See jasperreports-functions-5.6.1.jar at http://sourceforge.net/projects/jasperreports/files/jasperreports/JasperReports%205.6.1/

When using GlassFish, verify that you have all jasper libraries on your production server. They should be under glassfish/domains/domain1/lib/ext. If the jars are not there (or some of them, such as the fonts or some other not non-requisite lib) you might experience the behavior you are describing.
