How can I pass an object to a JSP tag?

Question

I have a JSP page that contains a scriplet where I instantiate an object. I would like to pass that object to the JSP tag without using any cache.

For example I would like to accomplish this:

<%@ taglib prefix="wf" uri="JspCustomTag" %>

<% 
 Object myObject = new Object();
%>

<wf:my-tag obj=myObject />

I'm trying to avoid directly interacting with any of the caches (page, session, servletcontext), I would rather have my tag handle that.

Answer 1

A slightly different question that I looked for here: "How do you pass an object to a tag file?"

Answer: Use the "type" attribute of the attribute directive:

<%@ attribute name="field" 
              required="true"
              type="com.mycompany.MyClass" %>

The type defaults to java.lang.String, so without it you'll get an error if you try to access object fields saying that it can't find the field from type String.
