Problem executing spark using startup.bat batch file

…/lib/spark.jar;…/lib/base.jar;…/lib/smack.jar;…/lib/windows/jdic.jar;…/lib /smackx.jar;…/lib/smackx-debug.jar;…/lib/dom4j.jar;…/lib/xpp.jar;…/lib/xstre am.jar;…/lib/i4jruntime.jar;…/resources org.jivesoftware.Spark

All jar files are present except org.jivesoftware.Spark in …/resources location.

and when i use this startup.bat file in command line to execute i am getting the error which states:

java.lang.ExceptionInInitializerError

at org.jivesoftware.Spark.(Spark.java:172)

any idea what to do here ? thanks in advance
