I tried turning these scriptlets into jstl tags with no success, is it not doable with these lines of codes, and if it can how so? thanks
<%
//String file = application.getRealPath("C:/science/");
File f = new File("C:/uploads");
String [] fileNames = f.list();
File [] fileObjects= f.listFiles();
%>
<%
for (int i = 0; i < fileObjects.length; i++) {
if(!fileObjects[i].isDirectory()){
%>
<%= fileNames[i] %> Download
<%= fileNames[i] %>
(<%= Long.toString(fileObjects[i].length()) %> bytes long)
<%
}
}
%>
Answer
All that code you have in the scriptles you have to do it in the java code and pass it to the jsp. I don't know if you are using any framework to do this but this is easy in frameworks like Spring MVC.
In your case you should create in java a bean with the properties you need such as isDirectory, length, name of the file, etc. Then you create a list of these beans and pass it to the jsp. Finally, you just iterate these list of beans in the jsp with a forEach loop of JSTL (http://docs.oracle.com/javaee/5/jstl/1.1/docs/tlddocs/c/forEach.html). You can google about it and you'll find lots of examples about how to do this.
Doing this you don't need to use scriptlets.
