Re: [rules-users] The Eclipse JDT Core jar is not in the classpath error
2009/6/2 Chris Richmond crichm...@referentia.com: Hello, I am using netbeans and ivy with Drools 5. I have successfully named, published the jars from drools to and could build my port of the stock ticker application in netbeans, but when I try to run it, I get the following error: java.lang.NoClassDefFoundError: org/antlr/runtime/tree/TreeNodeStream I have the antlr-runtime jar from the bin/lib on my classpath where I added all the others, but it always fails at this line In loadRuleBase() in Broker.java of the stock ticker sample builder.add( ResourceFactory.newInputStreamResource( Broker.class.getResourceAsStream( RULES_FILE ) ), ResourceType.DRL);. Does anyone have any ideas what jar I might be missing if it’s not the antlr-runtime? Thanks, Chris Hi, in one of my projects, I actually needed two different versions of antlr in the classpath. Did you check if the class referenced in the exception actually exists in the deployed antlr jar file?

RE: [rules-users] The Eclipse JDT Core jar is not in the classpath error
Marcus, I only have the one version of antlr jar that comes in the /lib folder of the drools 5.0 binary distribution, however that was enough to allow me to run the stockticker fusion sample in eclipse no problem. I ported the project to Netbeans and am relying on all of the same jars from that binary distribution, but getting this error now. Perhaps there is something that is being provided by the eclipse drools plugin?

Re: [rules-users] The Eclipse JDT Core jar is not in the classpath error
Chris, There must be a problem with the classpath. That message only shows up when the antlr-runtime jar is not in the classpath. java.lang.NoClassDefFoundError: org/antlr/runtime/tree/TreeNodeStream Also, I successfully run examples from command line, outside of eclipse, so it is unlikely that you are being hit by some hidden dependency. Sorry for not helping you more, but continue investigating your netbeans project classpath for odd things. Oh, and BTW, antlr runtimes are not compatible between versions, so, if your netbeans has a different antlr runtime jar in the classpath in a higher priority search order, it will give you similar problems.

RE: [rules-users] The Eclipse JDT Core jar is not in the classpath error
Ed, Thanks for the feedback. That's pretty much the conclusion I have come to..I will double check the higher priority reference, that sounds possible because we are using Ivy for dependencies with many package dependencies.. Thanks very much for the insights.
