jar is working fine but exe showing exception

Question

I am currently trying to make exe using launch4j to generate reports using the jasper. When I run the runnable jar, it is perfectly showing. But when I run the exe file, I always get an exception related to the jar dependencies. I have shown the jre folder while creating exe by launch4j. Despite this, I add the following jars file into my build path,

• jasperreports-5.6.0.jar
• commons-logging-1.1.jar
• commons-beanutils-1.8.2.jar
• commons.digester-2.1.jar
• commons-collections-3.2.1.jar
• groovy-all-2.0.1.jar
• jdt-compiler-3.1.1.jar
• jfreechart-1.0.12.jar
• jcommon-1.0.15.jar
• iText-2.1.7.js2.jar

the program generates me class not found exception either related with collections. My main goal is via using jrxml file to generate a report. I am using iReport 5.6.0 to generate jrxml file. Any help is appreciated. The Stack trace of error is below;
