In my case, this happens because of version mismatch of dtd. Here is the thing,

<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN" "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">

If we see the DOCTYPE there is a version "2.1" ("//DTD Tiles Configuration 2.1//EN") and the dtd should also be the same like "tiles-config_2_1.dtd". If the version is 3.1 ("//DTD Tiles Configuration 3.1//EN") and the dtd is "tiles-config_3_1.dtd".

I modified the version and its start working.
