Pascal has contributed some basic enhancements to allow formulas to be used to populate data in a cell
(rather then literal). 

This should be used with care.

[drools-user] Human readable rules

I've been looking at the Semantic Module Framework, however I found the Domain specific languages to be as
complicated if not more than the java stuff.

Is there a way to express rules in a more "human-readable" format ? Something like Subject Verb Object (e.g.
drools is good) would work really well for both conditions and consequences.

Regards,
Alan Ho

答复: [drools-user] Human readable rules

I think it should be a long way to reach it.
Now drools can't use by policy maker easily, it's just can be use be the programmer,maybe u can do some
mapping to make it more readable.
I am concern when will the friendly drl editor come out too.

[drools-user] Problems running unit test with drools 2.5 beta 2

Guys,

has anybody had any issues trying to run their drools unit tests from
eclipse with drools 2.5 beta 2. Everything seems to work well with 2.1 but I
get the following with 2.5 beta 2:

java.lang.NoClassDefFoundError:
org/eclipse/jdt/internal/compiler/env/INameEnvironment
at org.apache.commons.jci.compilers.JavaCompilerFactory.createCompiler(
JavaCompilerFactory.java:82)
at org.drools.semantics.java.JavaSemanticFunctionsCompiler.getInstance(
JavaSemanticFunctionsCompiler.java:27)
at org.drools.semantics.java.JavaFunctions.getSemanticFunctionsCompiler(
JavaFunctions.java:101)
at org.drools.smf.RuleSetCompiler.compile(RuleSetCompiler.java:166)
at org.drools.smf.RuleSetCompiler.<init>(RuleSetCompiler.java:67)

at org.drools.io.RuleBaseLoader.loadFromUrl(RuleBaseLoader.java:494)
at org.drools.io.RuleBaseLoader.loadFromUrl(RuleBaseLoader.java:479)

This seems to be because it's trying to pick up the Eclipse compiler instead
of the janino one which is on the classpath because of the following:

public class JavaSemanticFunctionsCompiler extends AbstractSemanticCompiler
    implements
    SemanticFunctionsCompiler
{
    private static SemanticFunctionsCompiler INSTANCE;
