Re: [jboss-user] [jBPM] - jBPM- Transaction isolation level

Maurice de Chateau [http://community.jboss.org/people/MohReece] replied to the discussion "jBPM- Transaction isolation level" To view the discussion, visit: http://community.jboss.org/message/541577#541577 -------------------------------------------------------------- Hi Alexander, You're not mentioning which version of jBPM you're using, but in the user guide for version 3.2.x ( http://docs.jboss.com/jbpm/v3.2/userguide/html/persistence.html#isolation... http://docs.jboss.com/jbpm/v3.2/userguide/html/persistence.html#isolation...) you can read the following: "+Make sure that the database isolation level that you configure for your JDBC connection is at least READ_COMMITTED.+ +Almost all features run OK even with READ_UNCOMMITTED (isolation level 0 and the only isolation level supported by HSQLDB). But race conditions might occur in the job executor and with synchronizing multiple tokens.+" So that's quite clear in itself. But if you want a little more background, you can read this JIRA issue ( *https://jira.jboss.org/jira/browse/JBPM-983 JBPM-983*), in which Tom Baeyens explains about the underlying reasoning for this persistence aspect.

You need to either increase the command line buffer size (mine is at 9000 lines) si that you can see the full first excpetion, or grab the first exception related to your app in the server.log file and post that. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/541542#541542] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - Access Spring Beans from jBPM installed as JBossAS service

I have web-application, build with using Spring and used jBPM 4.3 In process definitions I'm activelly using Spring beans for different handlers - hopefully jBPM 4.x has very good integration with Spring. Now, by some reasons, I want to move jBPM engine into service in JBossAS 5.1 (jBPM allowed to do it), get process engine from JNDI and use it from my application. Question is - in this case - are there any way to access from process definition, deployed into jBPM process engine, installed as separate service spring beans defined in my web-application? Has anybody expereince to setup such configuration? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/541532#541532] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Microcontainer Development POJO Server] - Implementing a non-flat deployment for Weld Integration

by Flavia Rainone

Flavia Rainone [http://community.jboss.org/people/flavia.rainone%40jboss.com] created the discussion "Implementing a non-flat deployment for Weld Integration" To view the discussion, visit: http://community.jboss.org/message/541531#541531 -------------------------------------------------------------- This thread is for https://jira.jboss.org/jira/browse/WELDINT-1 WELDINT-1. Taking a look at how the deployers are implemented today, I figured I should start by creating a non-flat version of WeldDiscoveryEnvironment first, so we could have a new environment input fot the new non-flat Deployment implementation. There a few assumptions I'm making right now that I would like to validate: - the deployment continues to exist per top level only, the only difference we are going to have is in the BeanDeploymentArchives (BDAs) - if Deployment.loadBeanDeploymentArchive requests for a non-existing BDA, I should search for all archives in the deployment that are not currently BDAs. If one archive containing the requested class is found, I create a BDA for it and return it. If the assumptions above are correct, the main question I have right now regards two different deployments that can see each other. So, in the scenario described by the Deployment interface javadoc example, whereas we have ejb-jar A and ear B. This is going to be translated in two different deployments, each one containg one or more BDAs (in the case of the ejb-jar, one BDA only). Since those BDAs can see each other, there must be a way for me to reach Deployment A BDAs from Deployment B BDAs. Is there some SPI in the current implementation of weld integration that supports that? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/541531#541531] Start a new discussion in JBoss Microcontainer Development POJO Server at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Datasource Configuration] - Multiple datasources different IP's Dynamic selection of each

by Ken Barnes

Ken Barnes [http://community.jboss.org/people/kenbarnesjr] created the discussion "Multiple datasources different IP's Dynamic selection of each" To view the discussion, visit: http://community.jboss.org/message/541523#541523 -------------------------------------------------------------- I have one jboss server that runs on a box with 30+ instances of sybase one the same box with each instance of sybase having a different ip. I have some web services that clients connect to wanting interaction with any one of the databases. I can get the Ip address of each that are calling but I need a way to specify the datasource via JNDI that each should use. Is there any way that I can have one datasource defined in Sybase-ds.xml and then in a module or some mechanism dynamically select the datasource according to IP and have the web service that utilzes the datasoure have the right one. Would i need 30 ds.xml files each creating a jndi datasource ?

Re: [jboss-user] [JBoss Microcontainer Development] - ClassPool bootstrap refactoring
