To pass the bean itself, you would need to say
<xxx:yy rs="<%= RS >"/>
instead.
However, I would recommend that the "rs" attribute of the custom tag class itself
should be a string -- and you can use it to pass the name of the bean that you are
interested in. For example, if your custom tag class has this:
private String rs = null;
public void setRs(String rs) {
this.rs = rs;
}
then you can access the actual object like this:
try1.Jsp5Bean myBean =
(try1.Jsp5Bean) pageContext.getAttribute(this.rs);
The nice thing about it is you can refer to a different bean of the same class (say
you stored it under id "XY") by saying:
<xxx:yy rs="XY"/>
