Some implementations of pageContext do not allow null values in the page
context (and other contexts as well).
There is a remove method that is supposed to be used for those situations.
Here is a fixed doStart method for DefineTag.
public int doStartTag() throws JspException {
// Retrieve the required property value
Object value = this.value;
if (value == null)
value = RequestUtils.lookup(pageContext, name, property,
scope);
// Expose this value as a scripting variable
int inScope = PageContext.PAGE_SCOPE;
if ("request".equals(toScope))
inScope = PageContext.REQUEST_SCOPE;
else if ("session".equals(toScope))
inScope = PageContext.SESSION_SCOPE;
else if ("application".equals(toScope))
inScope = PageContext.APPLICATION_SCOPE;
if( value==null )
pageContext.removeAttribute(id, inScope);
else
pageContext.setAttribute(id, value, inScope);
return (SKIP_BODY);
}
