Examples of JavaDialectConfiguration

org.drools.compiler.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 = 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.
