Hmmm... I'm sending this one more time as it hasn't appeared in the list as of yet. Apologies if two copies suddenly show up! -----Original Message----- From: Arun Thomas [mailto:[EMAIL PROTECTED]] Sent: Friday, January 07, 2000 10:04 AM To: JSP Mail List Subject: jsp:getProperty using is<Property> methods Hello all, I was reading through the excerpts from the book Drew mentions in his email on the thread "web app programming specifications query" (found at the site listed below) when I came across a section which caught my eye.... I've excerpted it below. Where would this kind of thing come in useful? Besides printing out either "true" or "false", is there any way to take advantage of the boolean nature of: <jsp:getProperty name="blah" property="aBoolean" /> assuming that this translates into a call to blah.isABoolean()? As far as I know, the <jsp:getProperty> tag isn't allowed to have a body, which means there's no way to do something conditionaly based on the result of the getProperty. Thanks very much! -AMT ---------------------------------------------------------------------------- ----- Boolean properties For boolean properties, that hold only true or false values, you can elect to use another Bean convention for getter methods. This convention is to prefix the property name with is, and return a boolean result. For example, consider these method signatures: public boolean isProperty(); public boolean isEnabled(); public boolean isAuthorized(); The container will automatically look for this form of method if it cannot find a property access method matching the getter syntax discussed earlier. Setting the value of a boolean property is no different then the setter methods for other properties. public void setProperty(boolean b); public void setEnabled(boolean b); public void setAuthorized(boolean b); ---------------------------------------------------------------------------- ----- > Finally, I have recently reviewed an upcoming book from Manning Publishing > called "Web Development with Java Server Pages" by Duane Fields and Mark > Kolb.
