Yeah, I wasn't necessarily responding to your JavaScript errors, just
the ECS compile error you were getting. Here are a couple things to
check for your JavaScript problem:
1. Depending on your servlet engine you need to make sure that the
scripts.js file is in the correct location. If you are using Tomcat
you'll need to make sure that this file ends up in
$TOMCAT_HOME/webapps/appname/ or some subdirectory underneath there that
you would refer to in your Script() call.
2. Depending on what you're trying to do with your JavaScript code, I
find that the best place to load my javascript source is in the <head>
portion of my HTML file. It all depends on where you are trying to call
the script code. I may be mistaken, but I'm pretty sure that if you are
using a script for a <body onload=""> then you'll need to have that
script loaded as part of the <head>. To do that move your "scrolling"
variable into the Head() declaration:
.addElement(new Head()
.addElement(scrolling)
);
Hope that gets you close.
