Instead of writing a main() class and doing your analysis inside it, you 
would probably find it easier to write a Driver. Then the existing 
hps-java code will take care of reading events from the file and passing 
EventHeaders to your Driver.

Roughly:

1. Follow the instructions to install and build hps-java (maybe you've 
done this already): 
https://confluence.slac.stanford.edu/display/hpsg/Installing+HPS+Java

2. Make a class that extends Driver, much like what you already seem to 
have in 
trunk/users/src/main/java/org/hps/users/spaul/HitrateHistograms.java. You 
can put your analysis code in the method process(EventHeader event).

3. Build hps-java to compile your Driver into an hps-distribution .jar 
file.

4. Write a steering file that calls your Driver, much like what you have 
in 
trunk/steering-files/src/main/resources/org/hps/steering/users/spaul/HitrateHistograms.lcsim.

5. Run the steering file on data:

java -jar hps-distribution-bin.jar -i lcioFile.slcio steeringFile.xml


If there's a reason a Driver is not appropriate for what you're doing, 
maybe we can figure something out that works. What you're doing now seems 
really strange without some more explanation.
