Re: [rules-users] Eclipse Debugging Drl file

by benq2188

Hello, I faced with the same problem. Breakpoints are not being hit by debugger. I have Eclipse SDK version: 4.2.1 and went through the reference manual of Drools and followed each step carefully. -Installed GEF - Downloaded drools-distribution-5.4.0.Final.zip -Unzipped it into Eclipse main folder -Restarted Eclipse -Defined run time based on the latest Drools project jars included in the plugin itself. -Created Drools Project -Created new launch configuration for Drools Application. -Put a breakpoint in the helloworld simple project on the first line of the section "then". When I debug it as Drools Application, debugger stops in Java breakpoints but doesn't stop in drl rule. Any solutions, how can I fix it? Thanks in advance. -- View this message in context: http://drools.46999.n3.nabble.com/Eclipse-Debugging-Drl-file-tp3870257p40... Sent from the Drools: User forum mailing list archive at Nabble.com.

Drools 5.5.0.CR1 is using a broken cdi-api version

by Cristiano Gavião

Hello, I'm using Tycho to create a dependency P2 repository (OSGi environment) containing JBPM 5.4.0.CR1 and DROOLS 5.5.0.CR1. I got some problem to properly setup the dependencies for the cdi-api. The bundle knowledge-internal-api has a dependency to cdi-api (version 1.0-SP4), but this version is tied to this: <groupId>org.jboss.spec.javax.interceptor</groupId> <artifactId>jboss-interceptors-api_1.1_spec</artifactId> <version>1.0.0.Beta1</version> And this 1.0.0.Beta1 version of org.jboss.spec.javax.interceptor was not well osgified. it doesn't have a Bundle-SymbolicName ! I could handle this problem using a newer version of it: <dependency> <groupId>org.jboss.spec.javax.interceptor</groupId> <artifactId>jboss-interceptors-api_1.1_spec</artifactId> <version>1.0.1.Final</version> </dependency> I won't use cdi anyway, but it could help others that decide to use jbpm with eclipse. regards, Cristiano

Adding custom metadata fields in guvnor

by sguruprasanna

Is it possible to add custom meta data fields in guvnor? Majority of our rules are EDI rules. So I was wondering if it is possible to have metadata fields to contain information like Trading partner name, or EDI format (820, 315 etc), etc so that the business users would be able to search for any EDI 820 rules, or any rules for tradingpartner XYZ etc.. Please let me know. Thanks Guru -- View this message in context: http://drools.46999.n3.nabble.com/Adding-custom-metadata-fields-in-guvnor...

Noob desperately needing help

by zaphod

So, we have a massive web-based application with a rules engine powered by drools 4.0.7...I have a time-based rule that fires, executes about 80% of the java code, and then just stops. No error, no exception, no nothing...it just stops. Until I restart the node, all rules processing is suspended. I've let this process run for 24 hours without intervention, but it really is hung. And I know it's not in a loop, as I'm outputting console messages, and I know the exact line that the app is hanging on. I have tried upgrading to drools 5.4, but we didn't write the kernel of the rules engine, and I'm not really in the mood to deal with re-writing it, unless I absolutely have to. This is the first time I've ever seen anything like this, and this app has been running for 4 years with no rules-engine issues. We use it everywhere....we are an EMS research organization supporting 3 states, and the application uses the rules engine to determine state-based EMS logic. We also use it as a timing trigger to email notifications to various EMS personnel to notify them of hospital facility closings, bed availability, etc. I have absolutely no idea what the problem is, or how to present it to the mailing list users in a way that might identify what the issue really is...so anyone who is game to help, ask me questions, and I'll answer them as best I can. Thanks for anyone interested in helping debug this issue....

Re: [rules-users] debug

by grandjean

Hello here is my way to proceed: download this drools version: http://download.jboss.org/drools/release/5.3.0.Final/drools-distribution-... unzip it download this: http://download.jboss.org/drools/release/5.3.0.Final/droolsjbpm-tools-dis... unzip it - Open Eclipse. - Open the menu "Help", menu item "Install new software..." - Click on the button "Add..." to add a new software site. - Fill in the name "drools local update site" - Click on the button "Local..." and select ".../binaries/org.drools.updatesite" (where u downloaded the droolsjbpm-tools-distribution-5.3.0.Final.zip) - Select all the plugins. Click the buttons "Next" and "Finish". U can create an "helloword" project so as to test quickly the debugger. & the breakpoint must be inside the THEN section. That's it! bruno -- View this message in context: http://drools.46999.n3.nabble.com/debug-tp3889772p3901720.html Sent from the Drools: User forum mailing list archive at Nabble.com.

JTA Persistence, Fact Objects and High Availability

by Miguel Paraz

Hi, I'm looking at the possibility of using Drools to store the working state of my app, in the form of rules. Can JTA Persistence store fact objects? I read that the fact objects must be Serializable - are there other requirements or caveats? Can JTA Persistence take care of High Availability? Even if the system goes down in the middle of a rules computation? Assuming the database handling the JPA is a HA system. Thanks! Miguel
