[Jboost-users] Error compiling Predict.java

[Filippo <son...@ya...>]

Hi, I'm studying JBoost 1.4 in this weekend on Windows XP. I succeded in run the demos and my training set. The tree is successfully build.
  Now I'd like to use the tree with java since it has the predictor just built in and I don't want to write a generic source in c to manage all types of input. But I cannot understand how to obtain the predictor.java from stem.java (for example).
  If I cut the section highlighted in stem.java, javac send me this error:
   
  predict.java:1: 'class' or 'interface' expected
  static private jboost.examples.Example ex;
                 ^
predict.java:8: 'class' or 'interface' expected
  static public void main(String[] argv) {
                ^
2 errors
   
  So I added the class name I find at the top of the original file stem.java, but now the I've mach more errors:

  Please, can you explain step by step what I've to do with stem.java to obtain predict.java under windows? Even if your project is interesting, as you may imagine, it's not usefull for me without prediction. :-)
   
  Thank you very much for your help!
