[JBoss JIRA] Created: (JBRULES-2101) Intermittant NullPointerException when invoking StatefulSession.asyncUpdate() while maintainTms==true

by Greg Barton (JIRA)

Intermittant NullPointerException when invoking StatefulSession.asyncUpdate() while maintainTms==true ----------------------------------------------------------------------------------------------------- Key: JBRULES-2101 URL: https://jira.jboss.org/jira/browse/JBRULES-2101 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL Environment: Ubuntu Jaunty Jackelope Linux version 2.6.27-11-generic (buildd@yellow) (gcc version 4.3.2 (Ubuntu 4.3.2-1ubuntu11) ) #1 SMP Wed Apr 1 20:53:41 UTC 2009 Multicore Reporter: Greg Barton Assignee: Mark Proctor After calling StatefulSession.asyncUpdate() the following exception occurs, but only when maintainTms==true in the rule configuration: Exception in thread "Thread-5" java.lang.NullPointerException at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1387) at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1350) at org.drools.concurrent.UpdateObject.execute(UpdateObject.java:46) at org.drools.concurrent.CommandExecutor.run(CommandExecutor.java:78) at java.lang.Thread.run(Thread.java:619) AbstractWorkingMemory.java line 1387 is wrapped in an if statement with condition "this.maintainTms" so setting maintainTms=false avoids the exception entirely. The NPE producing line is this: status = ((InternalFactHandle) factHandle).getEqualityKey().getStatus(); While encountering this problem the factHandle passed in to StatefulSession.asyncUpdate() was always non-null, so my guess is that the getEqualityKey() call returned null. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1675) Xpath Default Constraint Evaluations

by Paul Ryan (JIRA)

Xpath Default Constraint Evaluations ------------------------------------ Key: JBRULES-1675 URL: http://jira.jboss.com/jira/browse/JBRULES-1675 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Drl Parser/Builder, Eclipse IDE, Rule Assemply/SPI, Solver, Verifier, xml Reporter: Paul Ryan Assigned To: Mark Proctor A default set of constraint matchers for xpath based on loaded w3c DOMs would be very helpful. For our project we have alot of facts that are just an xml file (this seems to be the way the industry in general is going) that is calculated and being able to load that in to working memory and have constraint based node evaluations would be a very nice and attractive feature. I would suggest as a start a basic content equals (on elements it would match against text content and on attributes it would match against the node value) as well as a basic check for exists based on given xpath. Potential syntax: Fact( xml.xpath("/document//fragment[@id='myid']")) // Checks if the xpath exists in the property xml or Fact( xml.xpath("/document//fragment[@id='myid']") == "myvalue") // Checks if the text content of the fragment with the given id is "myvalue" or Fact( xml.xpath("/document//fragment[@id='myid']/@attr1") == "myattr") // Checks if the node value of the attribute attr1 in the given fragment is "myattr" with the property xml having been defined in the fact. I would suggest implementing this using the latest DOM stuff that has been recently released with xerces 2.9 and up as it has a very fast and efficient xpath evaluator. If you would like I think I can draw up some examples, however I don't think I know enough about drools core code to write this feature myself yet, maybe with some help. Also this constraint module may need a new interface for configuring the size limit (or other constraint) around when to load the xml into working memory. Maybe a annotation based solution in the fact is a good idea (e.g. put an annotation @LoadDOM on xml property in the fact for properties that should be loaded into DOM), or the other option is that the designer has to set the property up as an org.w3c.dom.Document for it to be consider pre-loadable. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (AS7-796) OSGi bypasses other DUPs when osgi metadata is found

by Jason Greene (JIRA)

OSGi bypasses other DUPs when osgi metadata is found ---------------------------------------------------- Key: AS7-796 URL: https://issues.jboss.org/browse/AS7-796 Project: Application Server 7 Issue Type: Bug Reporter: Jason Greene Assignee: Jason Greene Priority: Blocker If an EE, or JDBC driver happens to include osgi metadata, it will no longer deploy. This is because the OSGi subsystem bypasses other deployers, and treats it as just a bundle. Both Mysql and Hypersonic can not be deployed due to this problem. Ideally the OSGi subsystem would just add services and augment the model configs so that other deployers can function. Alternatively we can explore the possibility of deploying bundles differently than regular deployments, perhaps requiring special packaging, or extra deployment data. If we can't come up with a solution by CR1, I think we need to disable the OSGi subsystem by default. -- This message is automatically generated by JIRA.
