Include script inside tag code

Question

Hello,
I am trying to produce the same result as
<c:import url="some_file.jsp" />in my tag. For example, I have an object which holds a File object called "jspScript". I would like a tag that can be used this way.
<report:showCustomReport report="${report}" />inside the tag, the code would look something like this:
public class ShowCustomReportTag extends TagSupport {
    public int doStartTag() {
        File script = getReport().getJspScript();
        // <c:import url="${script}" /> ??
        return SKIP_BODY;
    public void setReport(CustomReportDisplay report) { ... }
    public CustomReportDisplay getReport() { ... }
}Any help is appreciated.

It appears (through use, never looked to hard) that the c:impot tag uses an HttpURLConnection to make a connection to the resource, then reads the response and either prints it to the page or stores it in a variable in scope.
Knowing that, your job would be to make an HttpURLConnection request to the given resource and read what it has to say.
It may be beneficial to identify where the resource is, ie: is it local to the ServletContext or an absolute URL beginning with a protocol.
If it is local, perhaps use a RequestDispatcher.include() to do the job. Otherwise do the whole HttpURLConnection thing...
Just a guess, though, on how c:import works.
