Jasper Report : Working with IN clause in SQL

Today had to work on a jasper report that has a IN clause in SQL.
The issue was , that the parameters were taken from UI in CSV format , so couldnt use the $X approach as described
http://stackoverflow.com/questions/6226447/passing-sql-in-parameter-list-in-jasperreport

The solution was

< parameter name="CNTRY_ID" isForPrompting="true" class="java.lang.String" / >
 < parameter name="CNTRY_ID_PARSED" isForPrompting="true" class="java.lang.String" >
        < defaultValueExpression >< ! [ CDATA [ $P { CNTRY_ID } . replaceAll(",","','") ] ] > < / defaultValueExpression>
    

and in the SQL query use it like

 where pt.subacct_id = gs.member_id
   and gs.CNTRY_ID IN ('$P!{CNTRY_ID_PARSED}')
 

Hope that helps

Handling classpath issues

Came across this issue today
java.lang.NoSuchMethodError    org.apache.commons.codec.binary.Base64.encodebase64

Eventually realized this was because the class Base64 was picked from wrong jar file... the ques was which one , I mean as i got this in web application ... so the hierarchy is not easy to trace.

I tried adding the following line before the exception
logger.debug(Base64.class.getProtectionDomain().getCodeSource().getLocation());

And then eventually modified the classpath settings to modify the issue.
