Hmmm, I can't see all that much which can go wrong in
the BlastLikeSAXParser constructor.  The two possibilities
are:

  - Can't access XML-parser classes (but you say you have
    xerces.jar on the classpath, so this /shouldn't/ be an
    issue).

  - The collections API isn't available.  If, as Mark says,
    J++ only supports Java 1.1, this is likely.  You could try
    compiling/running the following short program:


import java.util.*;

public class Test {
    public static void main(String[] args) {
        Map m = new HashMap();
        m.put("foo", "bar");
    }
}



If this compiles successfully, then we should maybe look
again.
