Hi there, I am working on business rule framework for our project which makes use of Drools API. We were using Drools 4.0.7 earlier and upgrading to Drools 5.5. One of our specific requirement was to fetch field name using ORConstraints and LiteralConstraints classes but seems like these classes have been deprecated in Drools 5.5. What's the alternative to these classes?? Also, while looking into Drools final 5.5 API documentation: http://docs.jboss.org/drools/release/5.5.0.Final/knowledge-api-javadoc/ I don't see classes such as org.drools.Rule, org.drools.RuleBase etc. Please let me know if I am referring to wrong API doc.?? Many thanks, Jeetendra. -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-5-API-doc-doesn-t-show-all-cla...

Thanks Mark. can you also please tell me the alternative to ORConstraints, LiteralConstraints. I read about fetching field inside condition that drools 5.x has better way to do it, without worrying about getting into internal classes. Any help will be highly appreciated.

Thanks Mark. This is really helpful. Can you please resolve my, hopefully, last query. So I am using JANINO compiler, and configured in code as below JavaDialectConfiguration javaDialectConfiguration = (JavaDialectConfiguration) packageBuilderConfiguration.getDialectConfiguration("java"); javaDialectConfiguration.setCompiler(JavaDialectConfiguration.JANINO); This gives me runtime exception: java.lang.NoClassDefFoundError: org/codehaus/janino/util/LocatedException at java.lang.Class.forName0(Native Method) [:1.6.0_35] at java.lang.Class.forName(Class.java:169) [:1.6.0_35] at org.drools.commons.jci.compilers.JavaCompilerFactory.createCompiler(JavaCompilerFactory.java:73) [:5.5.0.Final] at org.drools.rule.builder.dialect.java.JavaDialect.loadCompiler(JavaDialect.java:629) [:5.5.0.Final] at org.drools.rule.builder.dialect.java.JavaDialect.<init>(JavaDialect.java:190) [:5.5.0.Final] at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.newDialect(JavaDialectConfiguration.java:71) [:5.5.0.Final] at org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry(PackageBuilderConfiguration.java:337) [:5.5.0.Final] I have included janino-2.5.10 in class path. Let me know if I am doing anything wrong here. Thanks, Jeetendra. On Fri, Jan 18, 2013 at 7:31 PM, Mark Proctor <mproctor(a)codehaus.org&gt; wrote: 5.x supports free form expressions. This means it is not a trivial thing to analyse. In a pattern there will be 1..n strings for each expression. You'll need to build that string with MVEL and then analyse the MVEL AST tree. Take a look at drools-compiler PatternBuilder and MVELExprAnalyzer. These don't show how to extract fields, but it does show you how we analyse patterns for other mvel content.
