Well, using proper syntax is always a good first step. You say you can't
seem to get it to work, but don't contribute any information about EXACTLY
what you've tried... and what you're trying to do is mimic a javabean at any
rate, and there are better paths to attempt to go down than the one you've
chosen.
Here's a small test:
public class MyBean
{
String foo;
public MyBean() { foo=""; }
public void setFoo(String foo) { this.foo=foo; }
public String getFoo() { return foo; }
}
Drop this in the closest available WEB-INF/classes directory.
Then use this JSP:
<jsp:useBean id="mybean" class="MyBean" />
<jsp:setProperty name="mybean" property="foo" value="hello" />
<jsp:getProperty name="mybean" property="foo" />
Voila! You should see "hello" as output.
