[jboss-jira] [JBoss JIRA] (JBRULES-3349) Not possible to use Janino to compile templates

Not possible to use Janino to compile templates ----------------------------------------------- Key: JBRULES-3349 URL: https://issues.jboss.org/browse/JBRULES-3349 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-compiler Affects Versions: 5.3.1.Final Reporter: Adar Dembo Assignee: Mark Proctor I've got the following code in my program: {code} Properties props = new Properties(); props.setProperty("drools.dialect.java.compiler", "JANINO"); config = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(props); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(config); {code} The resulting KnowledgeBuilder compiles rules using the Janino compiler, which is important for me because I have an old JDT dependency that may not be updated. Now I'm trying to compile templates, and I've got the following code, based on the Drools documentation: {code} ObjectDataCompiler converter = new ObjectDataCompiler(); InputStream templateStream = this.getClass().getResourceAsStream("Templates.drl"); String compiledTemplate = converter.compile(clusters, templateStream); Reader compiledRules = new StringReader(compiledTemplate); ... kbuilder.add(ResourceFactory.newReaderResource(compiledRules), ResourceType.DRL); {code} Unfortunately, I see the [familiar JDT error|https://community.jboss.org/wiki/RulesTomcat] in converter.compile(), indicating that Janino is not being used for template compilation. I've spent a bit of time going through the source code and I don't see a way to do this.
