Hi,
I updated from 7.0p1 to 7.1 recently and JessDE doesn't recognize the stuff
specified in my BeanInfo classes anymore (it still works at runtime).
Is there some official changes in the introspection mechanisms?
Thanks for help.
I see there is a new restriction with 7.1 that slot names may not
contain a period ('.'). We will not be able to upgrade our platform
to 7.1 as long as this restriction is in place. We use URI's as slot
names, where periods are accepted and common (e.g.
http://en.wikipedia.org/wiki/URI
I could be wrong, but the restriction is needed because of the java
dot notation functionality.

Jess (defrule two-same-age-different-name
?person1 - (person)
?person2 - (person {age == person1.age lastName !=
Are these slot names generated by a program or written by hand? Is there any
chance of using %2e instead of a period? According to RFC 2396, this is an
alternative representation.

There are a couple of significant problems with that option:
1. We need to roundtrip the data. I.e. We have a middleware platform
with an embedded Jess engine. We need to be able to not only be able
to asserts facts based on data entering our platform, but also be able
to regenerate data based
It is interesting that such an OS-type term was chosen in the first
place. It seems like it would have been a risk, and here the risk has
come to fore. Perhaps in the new implementation you will choose a less
risky means to encapsulate the information in a data structure that may
be more similar
I think I'm missing something. Where did any OS-type terms enter
this?

It is
The dot '.' maybe I misread your posts but that seems similar to using
a slash or backslash '/ \'
Maybe there should be an acceptable set of characters listed (unless
this was one of the acceptable characters and they just took it off the
list, in which case that would be troublesome)
That's it exactly. The dot became a restricted character in 7.1.

The dot '.'
I could be wrong, but the new . dot notation is a new feature of JESS 7.
JESS 6 didn't support dot notation for accessing slots in the LHS or
RHS. In JESS 7.0, it didn't restrict the use of . in the slot name,
but JESS 7.1 does have the restriction.
I prefer lisp syntax myself, so I tend to stay

Jess itself
As folks have pointed out already, this restriction is in support of
the new Java patterns syntax, which gives special meaning to the
syntax templateName.slotName. Otherwise, Jess actually doesn't care.
As a temporary measure, you can comment lines 1293 and 1294 in jess/
Jesp.java, and the
12 matches
