@Puneet, Examples would be useful to understand what kind of problem you are having. As to Puneet wrote: > how can I detect which exact business rule is having error Check out "Debugging Rules" section of Drools documentation: http://bit.ly/9PRDRJ @Wolfgang, No need to be a hater Wolfgang, the question is simple. I agree, examples would be helpful, but that is NOT how you grow a friendly community. Community is the biggest problem JBoss has. Why is it so inhumanly difficult to be polite and considerate? /Anatoly -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Rules-doubt-tp774023p...

This is My rule rule "Area_SquareFt_01_10-01-09_12-31-14" date-effective "01-Oct-2009" date-expires "31-Dec-2014" salience 6 no-loop true when eval(BusinessLogic.gettest("Inside Area_SquareFt_01_10-01-09_12-31-14 executed")) objectP2483 : Para_2483( (fid2335=="Block") && (fid2336=="16") ); then System.out.println("Area_SquareFt_01_10-01-09_12-31-14 executed"); objectP2483.setFid31003(new Double(497)); end here My 31003 is a String field but i am assigning a Double in it so that should'nt work . But the problem is because of this my all remmaning rules also stoped working. And it took 2 hours to detect it because the execute() method dosent through any error. So how can we detect these situation earlier ,so as to catch the problem early and why my the remm rules stoped woking because on this.

Anatoly, please note that I wrote "please" to Puneet, which is usually not considered as being "impolite". Also, kindly note that I asked for more information, which, in my book, is not "inconsiderate", as simply deleting Puneet's post might have been. I do resent being called a "hater", and I'll let the community judge whether my (admittedly ironic) kidding is "hateful". Somehow, however, posters have to be admonished to state their problem more detailed, without people on the list having to waste their time playing guessing games or writing replies begging for more information. -W PS: A you can see now, it was not a question of "debugging", and so you have wasted your time on a "simple question". :-) On Tue, May 4, 2010 at 5:10 AM, tolitius <webakaunt(a)gmail.com&gt; wrote: > > > @Wolfgang, > > No need to be a hater Wolfgang, the question is simple.

Actually, this kind of error isn't discovered by the Drools DRL compiler; it would be flagged by the Java compiler. (You can verify: if you make the same error in Java code, you'll get that error message.) But if you are using dialect "mvel" (are you?), this is not flagged as an error, and it would silently convert the Double to a String, and set fid31003 to "497.0". Is this what keeps your other rules from firing, i.e., the excess ".0"? I suggest that you do not use "mvel" unless there is a compelling reason (in other rules). Even then, you might restrict use "mvel" to those rules where it is really necessary. -W 2010/5/4 Puneet duggal <duggalpunit(a)gmail.com&gt; > drlFile = BusinessRuleUtils.createCombinedDrlDocument(id,map.get(id)); > > PackageBuilder PACKAGE_BUILDER = new > PackageBuilder(BUILDER_CONFIGURATION); > org.drools.rule.Package pkg = null; > PACKAGE_BUILDER > .addPackageFromDrl(new StringReader(drlFile)); > if (PACKAGE_BUILDER.hasErrors()) { > DSM_LOGGER > .logFatal("Error has occured while building package.

Here, I've found this for you, a comment from the Drools source file org.drools.rule.builder.dialect.java.JavaDialectConfiguration * There are options to use various flavours of runtime compilers. * Apache JCI is used as the interface to all the runtime compilers. * * You can also use the system property "drools.compiler" to set the desired compiler. * The valid values are "ECLIPSE" and "JANINO" only. * * drools.dialect.java.compiler = <ECLIPSE|JANINO> * drools.dialect.java.lngLevel = <1.5|1.6> * * The default compiler is Eclipse and the default lngLevel is 1.5. * The lngLevel will attempt to autodiscover your system using the * system property "java.version" * * The JavaDialectConfiguration will attempt to validate that the specified compiler * is in the classpath, using ClassLoader.loasClass(String). If you intented to * just Janino sa the compiler you must either overload the compiler property before * instantiating this class or the PackageBuilder, or make sure Eclipse is in the * classpath, as Eclipse is the default. Try it without the JANINO setting - it *should* flag the setter with the incompatible types. If you haven't used MVEL so far, I don't see any reason to start now. -W 2010/5/4 Puneet duggal <duggalpunit(a)gmail.com&gt;: > @ Wolfgang Laun , > > i am using just this statement:- > > javaConf.setCompiler( JavaDialectConfiguration.JANINO ); > > I dont know the exact use of this statement .I am not using the mvel > , i tried to google abt it but couldnt find the use of this ... > can u through some light on this. > > Thanks > > > On 5/4/10, Wolfgang Laun <wolfgang.laun(a)gmail.com&gt; wrote: >> >> Actually, this kind of error isn't discovered by the Drools DRL compiler; >> it would be flagged by the Java compiler.

Would you please turn your screen a little more to the left and enlarge the font so that we can see what "mistake" you have made and what the error message is? It would also help if we could see when this "mistake" happens. -W 2010/5/3 Puneet duggal <duggalpunit(a)gmail.com&gt; > @ friends, > > > i am facing a problem in my business rules and it is :- > > > when i make single mistake in my business rule rest all rules > stops working ,why is it so ? and how can i detect which exact business > rule is having > error > > thanks > Puneet > > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
