Jasper can't export to a excel

[anirroy7]

Using Jasper 6.5.1 and poi 3.15 . It can't generate the desired .xlsx file. Tried with different poi version i.e 3.10.1,3.12 and 3.14
Giving an error :
java.lang.NoSuchMethodError: org.apache.poi.hssf.util.HSSFColor.getTripletHash()Ljava/util/Map;

Please provide me a solution.

You seem to be having a problem with Jasper, so probably best to post in a forum about Jasper.
