We are upgrading from Drools 5.1 to 5.3.0.Final, and running into issues with loading precompiled rule/ruleflow files. Previously, we precompiled our drl files using ant task "org.drools.contrib.DroolsCompilerAntTask", e.g. rule1.drl to rule1.drl.rules. We did the similar thing for ruleflow files, i.e. precompiled all of our rf files to a single ruleflow.flow file. In our java code, in 5.1, we load them as following: DroolsObjectInputStream ruleFlowStream = null; try { ruleFlowStream = new DroolsObjectInputStream( new BufferedInputStream( resourceLoader.getResource( "classpath:ruleflow.flow" ).getInputStream() ) ); org.drools.rule.Package ruleFlow = (org.drools.rule.Package)ruleFlowStream.readObject(); ruleBase.addPackage(ruleFlow); } ... Same thing for the rule files. My question is: How do we load the precompiled file in 5.3 (we switch to the KnowledgeBase API ) so that we can save the compiling time when loading? Thanks. -- View this message in context: http://drools.46999.n3.nabble.com/load-precompiled-rule-ruleflow-file-in-...
