Hi,
I was just attempting to solve the same problem for myself. I found a nice
piece of code in the archives that uses the class loader to find my files
and gives me an input stream. I am using it for finding property files but
there is no reason why it won't work for reading an HTML template.
ClassLoader cl = getClass().getClassLoader();
InputStream propInputStream = null;
String resourceName = "QFSecurity.properties";
System.out.println("Resource name: " + resourceName);
if (cl != null) {
propInputStream = cl.getResourceAsStream(resourceName);
}
if (propInputStream == null) {
//attempt to get the stream from the classpath
propInputStream =
ClassLoader.getSystemResourceAsStream(resourceName);
}
if (propInputStream == null) {
//prop file is unretrievable
String msg = "unable to locate property resource: "
+ resourceName;
config.getServletContext().log("[Initialization
Error] " + msg);
throw new ServletException(msg);
}
at this point, you have an input stream to your file and all you needed to
know was its name and the fact that it is in the classpath somewhere.
