While its possible that this is due to a classpath mismatch between compile-time and run-time its not necessarily true. A typical Java program can.

What I installed from GlassFish JSTL 12 is the implementation JAR file. Instead it calls upon the Java Classloader to load classes in memory as-and-when-required.
