Re: NullPointerException in while initializing message resource

2006-04-05 Thread Ramkumar Krishnan

Hi Ganesh,
 thanks for your reply. But my properties file is directly under  the
WEB-INF/classes folder, not under any package.

regs,
Ramkumar

 Hi,

 You should specify the full package location of the message-resource
 file..
 The parameter should be like this..
 message-resources parameter=com.vrst.self.struts.ApplicationResources
 /
 Hope this helps..!

 Thanks,
 Ganesh.

form field is not populating immediately

2005-06-13 Thread Ramkumar Krishnan

Hi All,
 I have a form which has two fields.One is a string array and
another field which determines the size of the first field. i have
indexed methods to populate the string array.

i need to initialize the string[] based on the size(another form
field) when the indexed method gets invoked. But my second form field
is not populated by the struts.
Because of this i am getting null pointer exception.

This is my indexed method in my form
..
 public void setDisabledUser(int index, String object)
{
if (arr == null)
arr = new String[Integer.parseInt(getTotalSizePerPage())];
arr[index] = object;
}
...

getTotalSizePerPage() returns null because the form field is not yet
populated by struts when this method gets invoked.


Any clues to solve this problem?

thanks in advance,
--
