Replace boolean with yes or no

[ag201]

hi guys,

 

i have this boolean value field, which i want to display as Yes or No, instead of true or false respectively. Can somebody tell me how i can do this.

 

thanks.

you could use the PrintWhenExpression of that textfield.

 

I don't know, how it looks like, so it is a bit speculation...

 

so, try it like

 

$F{DBField}==true : "yes" ? "no"

 

or something similar. For that, the textfield has to be a String - field.

 

hope this helps a bit

Very close. The expression would be something more like

 

$F{DBField}.booleanValue()==true ? "yes" : "no"

doesnt work for me. i am getting a bunch of errors.

 

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. The method booleanValue() is undefined for the type String value = (java.lang.Boolean)(((java.lang.String)field_can_centrifuge.getValue()).booleanValue()==true ? "yes" : "no"); <----------> <----------------------------------------------------->

any ideas?

guys let me back up ok.

 

my sql query returns a field which is a boolean in the DB. so now i create a field in my report with type string and right click on it select properties, use this as the print expression, $F{is_loggedin}.booleanValue() == true ? "Yes" : "No" for it. now when i go under view->fields, under that i have is_loggedin as string too.

 

now sometimes i am getting the error saying that booleanValue is not the right function for a string and sometimes i am getting cannot cast from string to boolean. i have done this in the past, but now am totally stuck.

 

any help guys.

if your field is of type String, you have to take the .equals() function,

 

so

 

Code:

$F{loggedIn}.equals("true"«») 

and so on. Or, if you are not sure, if its lowCase or not, you can take equalsIgnoreCase("")...

 

Hope this helps a bit...
