Re: [rules-users] Is there any way to compress (gzip) the rules package to optimize network traffic between server and agent?
Nothing out-of-the-box AFAIK, but a patch (or better yet a pull request) is welcome. Just wrapping both ends in ZipOutputstream and ZipInputstream should do the trick, but then we'd have always zipping, but we might want it optional. If we want optional zipping, the client should include a header/argument to the server to ask it in zip format (similar like the HTTP protocol) and the server should always support both (just do what the client asks him to do). That we we don't rely in the client and server having to be configured the same and crashing wierdly if they aren't.

Ok, but I have to modify the class org.drools.agent.impl.KnowledgeAgentImpl for it to do unzip the package on the client.

Re: [rules-users] Is there any way to compress (gzip) the rules package to optimize network traffic between server and agent?
Whilst I don't believe there is anything "out of the box" could you just not write a JEE5 javax.servlet.Filter to perform the compression for you?

[rules-users] Is there any way to compress (gzip) the rules package to optimize network traffic between server and agent?
We have a drools application composed of almost 1000 rules. The rules deployment package has almost 8MB and we need to distribute it over a 100 Kbps network for offline use on some client machines. If we could zip this package, it would require only 237Kbytes (instead 8MB). It seems, however, the class org.drools.agent.impl.KnowledgeAgentImpl doesn't support gzip compression. Is it right? Is there any workaround for this problem?

[rules-users] Removing rule (DRL) from resource throwing NullPointerException...
Hi, I am using Drools Kbase stateful sessions and using "changeset.xml" file to dynamically load resources (DRL files) from a folder. The KnowledgeAgent configuration property 'drools.agent.newInstance' is set to false. And the 'drools.resource.scanner.interval' property is set to 1. As I am using Spring, these properties are passed-in to the agent from spring-beans.xml. Now, when I start tomcat, everything works fine (some rules also get fired), But when I remove a DRL rule from my resource folder following exception is thrown: Exception in thread "Thread-8" java.lang.NullPointerException at org.drools.reteoo.RuleTerminalNode$RTNCleanupAdapter.cleanUp(RuleTerminalNode.java:507) at org.drools.reteoo.BetaNode.doRemove(BetaNode.java:253) at org.drools.common.BaseNode.remove(BaseNode.java:109) at org.drools.reteoo.RuleTerminalNode.doRemove(RuleTerminalNode.java:411) at org.drools.common.BaseNode.remove(BaseNode.java:109) at org.drools.reteoo.ReteooBuilder.removeRule(ReteooBuilder.java:237) at org.drools.reteoo.ReteooRuleBase.removeRule(ReteooRuleBase.java:432) at org.drools.common.AbstractRuleBase.removeRule(AbstractRuleBase.java:831) at org.drools.common.AbstractRuleBase.removeRule(AbstractRuleBase.java:809) at org.drools.impl.KnowledgeBaseImpl.removeRule(KnowledgeBaseImpl.java:206) at org.drools.agent.impl.KnowledgeAgentImpl.removeKnowledgeDefinitionFromBase(KnowledgeAgentImpl.java:842) at org.drools.agent.impl.KnowledgeAgentImpl.incrementalBuildResources(KnowledgeAgentImpl.java:763) at org.drools.agent.impl.KnowledgeAgentImpl.buildKnowledgeBase(KnowledgeAgentImpl.java:586) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:185) at org.drools.agent.impl.KnowledgeAgentImpl$ChangeSetNotificationDetector.run(KnowledgeAgentImpl.java:1106) at java.lang.Thread.run(Thread.java:662) Is there anything more that needs to be set for 'changeset' to work for add/update/remove of resources?
