That anonymous class is not about "arg", but is referring the cps,
which is created on jdbc.rb line 299,
basically when it runs to
cps.setDate(i.arg)
exception is thrown.
The funny part is, the switch/case statement will recognize arg as a
Date type, but next line when Jruby tries
to resolve cps.setDate, it fails to recognize arg as a Date.
Here are the modified jdbc.rb to show some debug info
def set_ps_arg(cps, arg, i)
puts "Debug arg class is #{arg.class}, arg value is #{arg}"
case arg
....
when Date, Java::JavaSql::Date
begin
cps.setDate(i, arg)
rescue Exception=>e
puts e.message
puts e.backtrace
end
.....
else
cps.setObject(i, arg)
end
end
And here are the output:
Debug arg class is Date, arg value is -2010-10-12
no setDate with arguments matching [class org.jruby.RubyFixnum, class
org.jruby.RubyObject] on object #<#<Class:01x41692a49>:0x705789f3>
