Hi,

 

This error appears in one of the report

expressions.

 

If we are talking about the FirstJasper.xml

sample, and you have not modified it,

then certainly the error comes from the

FirstLetterGroup expression (FisrstLetter variable expression),

which has a "substring" method call.

 

If in your database the ShipCountry field might

be null or empty, then you should protect the

group expression by adding a length test before

applying "substring" like this:

 

<variable name="FirstLetter" class="java.lang.String" resetType="None" calculation="Nothing">

<variableExpression>

<![CDATA[

($F{ShipCountry} != null && $F{ShipCountry}.length() > 0)?$F{ShipCountry}.substring(0, 1).toUpperCase():""

]]>

</variableExpression>

</variable>

 

In the supplied database, there was no need for

such an expression since all the records

contained a not null and not empty ShipCountry

field value.

 

Good luck!

Teodor
