The JessToken.toString() method that you're calling isn't used
internally by Jess; it's just for debugging. But as it turns out,
you've found a bug in it -- it apparently doesn't properly convert
RU.LONG values! A patch for jess/JessToken.java in Jess 7.0p1 could
look like
diff -r1.27 JessToken.java
87a88,89
> else if (m_ttype == JessToken.LONG_TOK)
> return String.valueOf(m_lval) + "L";
Otherwise, a workaround would be
jt = rt.nextToken();
if (jt.m_ttype == JessToken.LONG_TOK)
System.out.println("Tok="+jt.m_lval + "L");
else
System.out.println("Tok="+jt.toString());
Typically, consumers of JessToken objects wouldn't turn around and
convert everything back to a String like this, though. The JessToken
class stores int and double values in m_nval, Strings and tokens in
m_sval, character values in m_ttype, and longs in m_lval, and you'd
probably want to use these values directly.

nextToken method returns a "" for the list values. I tried upper

I need the L's because the costctr variable is defined as a long in
a Java Class, and the member$ won't find a match otherwise. I'm
using Jess 7.0p1. Sample java code and clp file attached.
