Answer 1

Answer 2

<s:property value="%{myMethod(myVariable)}" />

is a correct syntax, but to get the value of the method that have a signature

public String myMethod(String value){
  return value;
}

required the getter for myVariable

public String getMyVariable() {
  return myVariable;
}

if you set the value to myVariable like

private String myVariable = "myValue";

then it should be printed in JSP. If the argument is other type it will be converted to String and the method will call.
