Subject Re: Error dispatching bean action via URL pattern
Date Mon, 24 Jan 2005 16:23:24 GMT
Hi Rahesh,

Do you do the data load on to the target database you are using.  If the data is missing you
can
get the following error.  It is possible that you created the tables but did not upload the
data. 


One of the common reasons of NullPointerException in iBatis is when you define the bean with
a
primitive data type and when you insert the data into the database you are inserting NULL
and when
you are retrieving the data back you are not defining in your SQL map how the NULL should
be
treated.

iBatis performs the Obj.getFloatValue() or Obj.getIntValue() etc.

Rgds
Prashanth.
