Hi... Check all the java class names where ever you used in your report.. like at parameter types, field types..  

[sanbez]

groovy-all-1.7.5.jar   does not contain the class    org/codehaus/groovy/runtime/BytecodeInterface8

Check libraries used for compiling report (or groovy-x.y.z.jar in tomcat?)
