[TM4J-users] TologParser Exception - unexpected token

[Richard G. <ric...@ya...>]

Hi,

I have the following code which adds a tolog rule and then executes a query using that rule, based
on example 8.2 of the tm4j development guide. 

queryEval.addRule(
	"func-loc($PROTEIN, $LOCATION, $FUNCTION) :- { " +
	"at-located-in($LOCATION : tt-loc, $PROTEIN : tt-protein), " +
	"at-has-function($FUNCTION : tt-function, $PROTEIN : tt-protein) }.");

			
TologResultsSet results = queryEval.execute(
	"select $PROTEIN, $FUNCTION, $LOCATION from { " +
	"topic-name($FUNCTION, $FUNCTION_NAME), " +
	"value($FUNCTION_NAME, \"11.06.01 rRNA modification\"), " +
	"topic-name($LOCATION, $LOCATION_NAME), " +
	"value($LOCATION_NAME, \"70.10.07 nucleolus\"), " +
	"func-loc($PROTEIN, $LOCATION, $FUNCTION) } " +
	"order by $PROTEIN?  ");

However, when I run the code I get a TologParserException message, suggesting that it doesn't like
the closing '}' in my rule. 

Exception caught: org.tm4j.tologx.TologParserException: Parser error in rule string.
org.tm4j.tologx.TologParserException: Parser error in rule string.

        at org.tm4j.tologx.memory.QueryEvaluatorImpl.addRule(QueryEvaluatorImpl.java:132)

I also tried using the addRulesModule() method, but I get the same exception generated by the same
part of the rule.

I anyone can tell me where I'm going wrong here (as I'm sure it's something I'm doing wrong), I'd
be grateful.

Cheers,

Richard.
