I using Jasper report ver 0.6 know i would likes to upgrade it to ver 1.2.5 i had configured totally as per the Requirment.html from jasper site setted all the jar to the classpath:

gives me this error :

 

java.lang.NullPointerException

at java.util.Hashtable.put(Unknown Source)

at net.sf.jasperreports.engine.fill.JRFillDataset.setParameterValues(JRFillDataset.java:574)

Hi,

 

Yes, this seems to be a problem.

Until we fix it, you could try pass parameters in a HashMap instance, which accepts null values, instead of a Hashtable instance.

 

I hope this helps.
