birt-runtime-4_2_2

i have already set the BIRT_HOME in environmental variables
variable value = F:/birt-runtime-4_2_2/birt-runtime-4_2_2/ReportEngine

in eclipse
CLASSPATH = BIRT_HOME-F:/birt-runtime-4_2_2/birt-runtime-4_2_2/ReportEngine/lib

the code where the error is showing
try {
Platform.startup( config );

Can you attach your code?

Also, have you seen this devShare about integrating Spring with BIRT?
