Java class not found

Good afternoon,

I would like to think this question has been asked and answered before but I'm not having the best time naving the updated forum. Anyway, I have a compiled Java application that I cannot read with CF. This is my error message: Object Instantiation Exception. Class not found. My jar exists in here: <cfset THIS.javaSettings = {LoadPaths = ["/ReaderRFID/lib"], loadColdFusionClassPath = true, reloadOnChange=false}/>.

My  output page:

<cfset jar = CreateObject("java", "AlienClass1ReaderTest")>

<cfset readTags = jar.AlienClass1ReaderTest>

<cfoutput>

#readTags#

</cfoutput>

The class should be called from the jar but nothing happens. Any help is always appreciated. Thanks!
