I am new on JSP. My simple if condition is not working properly.

//row.getString("labels.above") is taken from database its value is "true"

< input type="radio" <% if(row.getString("labels.above")=="true"){ %><%="checked" %><% } %> />True

but it is not marking check on radio button.

this condition must be true. as
this:

 <%=row.getString("labels.above")%>:<%="true" %>

Output:

true:true

For String comparison use String#equals() method instead of ==

It should be 

"true".equals(row.getString("labels.above"))

I suggest you to use JavaServer Pages Standard Tag Library or Expression Language instead of Scriplet that is more easy to use and less error prone.

Don't compare strings in java using the == operator.

The short story is that == will test to see if the two strings reference the exact same object, while the .equals method will test if the strings match character-for-character. In almost all cases, you want to check using .equals
