[rules-users] adding process to an empty rule base

2007-07-27 Thread hypnosat7


Is it possible to set the rule flow in my rule base before adding rule
packages :

ruleBase = RuleBaseFactory.newRuleBase();
org.drools.compiler.ProcessBuilder processBuilder = new ProcessBuilder(new
PackageBuilder());
processBuilder.addProcessFromFile(ruleFlow);
ruleBase.addProcess(processBuilder.getProcesses()[0]);

thanks

Re: [rules-users] adding process to an empty rule base

2007-07-27 Thread Kris Verlaenen

This error is caused by a mismatch between the version of the mvel library 
you are using and the version that is expected by drools.
Drools 4.0.0 is expecting mvel14-1.2rc1.jar.  Previous versions of drools 
are probably based on older versions of mvel.

Might also be caused by having multiple versions of mvel in your classpath.

I try this:

Reader ruleFlowReader = new InputStreamReader(stream);
ruleEngine.setRuleFlow(ruleFlowReader);
..

PackageBuilder builder = new PackageBuilder();
builder.addRuleFlow(ruleFlow);
Package pkgRuleFlow = builder.getPackage();
ruleBase.addPackage(pkgRuleFlow);

Re: [rules-users] adding process to an empty rule base

2007-07-27 Thread hypnosat7


If I do like this, it works :

PackageBuilder builder = new PackageBuilder();
Reader drlReader = new
InputStreamReader(getClass().getResourceAsStream(/emptyPackage.drl));
builder.addPackageFromDrl(drlReader);
builder.addRuleFlow(ruleFlow);
Package pkgRuleFlow = builder.getPackage();
ruleBase.addPackage(pkgRuleFlow);

In the emptyPackage.drl file this no rules, but it seems to be impossible to
have a rule base with only a rule flow. I hope I'm wrong :)
