Hi,

There are two errors in msg.setContent("LOG :message \"JADE\" ")
1) It should be msg.setContent("(LOG :message \"JADE\")")
Nothe the ()
2) The SL language does not allow to use an expression with named slots, i.e. an expression like
(Type :slot1-name slot1-val :slot2-name slot2-type ...)
at the first level of a message content. That is expressions with named slots can only be used within an expression with un-named slots.

Bye

Giovanni

Hello!

I'm building my ontology and send a message in this ontology filling it before with the fillMsgContent command.

When I receive this message in another agent I get problems in the extractMsgContent command.

I'm filtering messages with the MatchOntology and MatchLanguage commands. To debug the message contents I explicitly set the contents:

msg.setContent("LOG :message \"JADE\" ")
List l = extractMsgContent(msg);

The last command produces a SL0Parser exception: Something like - "found :message, expected (, "STRING_LITERAL" ".

I've tried to work with the string ("LOG \"JADE\" ", but the parser wants the slot "message".

Any suggestions?

Alexander
