My app is quit big and using many jars and tools. Platform - windows 2008 server, Spring , hibernate, Quarts, mysql, tomcat-7.35
When I deploy and start the server first
In My case iTextpdf JAR(5.06 version) causing problem as it had dependancy on org.bouncyCastle.*.jar and it was creating cyclic dependancy.
org.bouncyCastle.*.jar
After updating it to 5.5.6 version, worked perfectly. If you are adding maven dependancy , clean and update maven project.
5.5.6
com.itextpdf itextpdf 5.5.6
