Easy way of Substracting,Adding Months or Days from parameter date in Jasper studio or iReport : Ex : Substracting 2 months from current date

This is re-blogging of Right outer join post in simple understanding.


This post avoid the complexity usage & guide you the simplest way.

Aim : 
1) Subtract 1 month or 2 months or 3 months and etc from current date or selected date.
2) Subtract1 day or 2 day or 3 day or etc from current date or selected date
3) First Day of last month, Last day of last month & 15 th day of last month
4) Number of days from the current date or selected date.
5) Other Date formats

Sample output:

Way of getting solution :

1) Very first thing is to import org.apache.commons.lang.time package by opening XML source.  You have to add this code after properties selection ( The first high lighted code )

2) Take a parameter called MyDate and it's type should of java.util.Date

3) Now do experiment with various methods that available from org.apache.commons.lang.time

4) For eg :  Subtracting 2 months from MyDate parameter 
  Lets say MyDate parameter default value new Date() [1/2/15/ 1:04 P.M]
Below expression in a text field gives you the the exact subtraction of 2 months

<textFieldExpression><![CDATA[DateUtils.addMonths($P{MyDate},-2)]]></textFieldExpression>


5) Copy the below code and paste in your jrxml and see the magic.

6) Now how to get the patterns of dates
Lets create another parameter  say PatternDate and in its default expression write below code...
The type of this parameter should be of java.lang.String
$P{PatternDate} = new SimpleDateFormat("MMM-yyyy").format($P{MyDate})

Place this parameter in Title section and check the pattern....

Or you can directly set pattern by going properties if you are printing dates in a Text field.
