[rules-users] matches operator
Hi, Has anyone used the matches operator? In our application we need to support startWith, endsWith operators for string variable. I am thinking of using matches operator. But the 'matches' operator is not working. I am trying the following code rule Hello World when m : Message(message matches Hello*) then System.out.println( Hello World); end And the value set in the message is Hello World. But it is not going into the then clause. If anyone has already used matches operator I would like to know how we can use it for startswith, endsWith. How do we specify the regular expression?

As an example, in Shipment.Header we'd have a port.Lading with a numeric value of 901 and in District.Port, it would be the character equivalent of 0901 zero filled. thanks, Mike -- View this message in context: http://www.nabble.com/toString-tf4029720.html#a11498978 Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

RE: [rules-users] JBoss Drools vs JBoss Rules
Mark, As a long-time member of Jboss Rules/Drools community, first, I want to thank the team for quoting me in the Drools 3.0 documentation. It's nice to know that there are people in the community who respect my opinions. I didn't realize that my comments made it into the document, but I'm honored. In regard to the name game... I have to admit that as an old-timer, I had some difficulty switching to the Jboss Rules moniker. Overall, I prefer the Drools branding, due to the fact that it harkens back to the history of the technology that the Drools team developed. Speaking of history age, my age and subsequent memory loss prevents me from recalling the genesis of the Drools name.

Re: [rules-users] Re: 4.0 Language Updates
Ronald, Take a look at the class and it will be easy to understand: http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-core/src/main/java/org/drools/base/evaluators/BigDecimalFactory.java != for big decimals is translated to return ! val1.equals( val2 ); In both cases, it is delegating to the object equals() method, that in case of BigDecimal, compare values, not references ( identity ).

On M3? if you look at the JavaDialect you should see that the source is always set ti jdk1.5, can never go below that, but the target is 1.4 - which should allow static imports in a jdk1.4 environment.

Re: [rules-users] 4.0 JBoss Rules IDE - JDK 1.4 compiler setting
Mark, I would be happy to help. The short answer is that, I need my entire project - Java classes and all in JDK 1.4 format. When I tried playing with the settings in Eclipse it keeps telling me that either source or class files that are generated must be at or above the other's level. It does not look like I can mix and match the two of them. I guess my alternative would be to create an ANT script that generated the 1.4 JAR file. BTW..it does run just fine and like a champ!
