<div dir="ltr">Hi <div> I am attelmpting to use Javasci. I am able to run javasci as a standalone program in eclipse, however when i run it as a part of a sptring servelet i get the following exception though the jars are included in the classpath. I have tried configuring the build path pointing to the two jars and also tried adding maven external jars dependency via system scope. This happens only when run as a spring application.</div>
