The 49.0 is a magic number within the class bytecode. This type of error 
typically means the class was compiled using a newer version of the jdk 
than the runtime that is interpreting the bytecode. So, did you, say, 
compile the lawSearch class using jdk 1.5 but are running Tomcat against 
  jdk 1.4?

Resolution: recompile lawSearch against jdk 1.4
