Re: [jboss-dev-forums] [JCA Development] - JcaXAResourceRecovery

They are included in both, the EAP5 branch and trunk. Currently, the recovery tests run against selected databases inside the redhat network, namely PostgreSQL 8.2 and 8.3, Oracle 10g and 11g, Sybase 15, DB2 9.7, MSSQL 2005 and 2008, MySQL 5.0 and 5.1, i.e. supported db's for EAP. They don't use Derby at the moment. The current tests involve only XA-datasource for each supported db in crash recovery and there is a question what other types of JCA XA resources they could involve into the recovery testing. It is subject for discussion. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534595#534595] Start a new discussion in JCA Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Adrian Brock [http://community.jboss.org/people/adrian%40jboss.org] replied to the discussion "On demand resolution" To view the discussion, visit: http://community.jboss.org/message/534591#534591 -------------------------------------------------------------- > Ales Justin wrote: > > > I created a test for DynamicImport-Package to check whether https://jira.jboss.org/jira/browse/JBCL-131 https://jira.jboss.org/jira/browse/JBCL-131 is actually working at the OSGi layer. > I fail to see how dynamic import and JBCL-131 are related? > JBCL-131 is an impl of OSGi' lazy bundle activation -- e.g. only invoke BundleActivator if some class from that bundle needs to be loaded. Well actually JBCL-131 is about lazy resolve, not lazy start. It's not working because it hasn't been enabled. I've committed the following patch which makes it work using Ales's DeploymentMetaData (I've not done anything with lazy start). I don't know if that is the correct place for it? Another question is whether you always want to enable lazy resolve for OSGi, even if the user specifies something else? P.S. There's no point re-opening issues in closed releases.

That is the root of the problem here. Yeah, I've played with that, and that seems to work fine. The tests failing already had a policy file, just missing this permission (for my new stuff), so I assume this is ok. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534495#534495] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
