hi guys
iam trying to populate values from jsp to a formbean when i submit the form
every thing works fine
but if didnt fill the data for a text box the corresponding property in formbean is populated with empty sting("") eventhough i initialized the property with statement like below
private String searchString=null; but for other properties if i didnt enter any value null is populating

looking for your replies
amir

Form bean values are populated as per request parameter values. If its textbox then its request parameter value is "". So its not a null value.

Why should you need a null to be returned ?
What ever the condition you are checking you can check for "" instead of null.

I think by default it will give only "" for string .

You said you are getting null value for other fields what's the data type for those fields?
 
It is sorta covered in the JavaRanch Style Guide.
