How do I pass an attribute of type, java.util.ArrayList<my.entity.Property> to a Tag implementation class?
Please advise!

import my.entity.Property;
public class PropertiesTag extends SimpleTagSupport {
    private ArrayList<Property> properties;
    public void setProperties(ArrayList<Property> properties) {
          this.properties = properties;
     public void doTag() throws JspException, IOException {

</taglib>Here's the error message:

As already pointed out, there is no way to specify a generic type in a tag library descriptor. You may however specify an Object type in your tld and still have the variable in your tag as a parameterized generic type.
In your tld change the type to Object.
<type>java.lang.Object</type>.
The properties tag itself needs no change and can continue to use parameterized types.
