Hi, I think you have to use "Test\\s+". I don't think it's a DROOLS problem (maybe jdk). V. -----Message d'origine----- De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de Markus Helbig Envoyé : mercredi 10 octobre 2007 11:12 À : rules-users(a)lists.jboss.org Objet : [rules-users] pattern Drools Documentation says: Matches a field against any valid Java Regular Expression. Typically that regexp is a String, but variables that resolve to a valid regexp are also allowed. It is important to note that different from java, if you write a String regexp directly on the source file, you don't need to escape '\'. Example: but "Test\s+" is a valid RegEx (it was valid in Drools 3.x too), but now: SyntaxfehlerRule Compilation error : [Rule name=OnlineStreaming Start, agendaGroup=MAIN, salience=100, no-loop=true] com/p7s1/swi/phoenix/n24/Rule_OnlineStreaming_Start_0.java (19:923) : Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ ) What i'm doing wrong here?

Markus, Yes, eval code block will pass through DRL compiler into the java compiler. So you need to write the regexp as it is written in standard java code. Now, this must work: Item( title matches "^Test\s*" ) Does not matter what characters title contains. If it is not working, it is a bug. Can you please submit a JIRA with a test case showing the problem?
