Hi Tim, the transaction control service sounds interesting. I haven't found some example or tutorial which shows how to used it with JPA. Do you know whether something like this exists? Would be helpful to get started. I'm sure that the documentation pages contain all relevant information, but

Re: Removal of start levels from Karaf 4.0.2 onwards - transaction manager not available in time

Hi Tim, you should create such a feature in the tx-control code in Aries. For example the Aries jpa code already has such a feature now. This allows people to install their desired version independently from the karaf version. As soon as you have this feature I can then add it to the karaf

The depend-on flag on the bean element can be used for that. The JPA 2.x Aries bundles should solve the service dependency problem and be better integrated with the pax-jdbc config stuff. 2016-07-11 9:37 GMT+02:00 jochenw : > Hello, > > start levels have been

Re: Removal of start levels from Karaf 4.0.2 onwards - transaction manager not available in time

Hi Jochen, You’re absolutely right that start levels (and startup ordering) are anti-patterns in OSGi. It’s also the case that Aries Transaction and older versions of Aries JPA (the 1.x releases) are really hard to use. Aries JPA 1.x does not always wait correctly for the datasources that it

Could you give a bit more information on how your persistence bundle is used ? The EntityManager / EntityManagerFactory should only be available in the OSGi registry once everything is ready... 2016-07-11 9:37 GMT+02:00 jochenw : > Hello, > > start levels have

Removal of start levels from Karaf 4.0.2 onwards - transaction manager not available in time

Hello, start levels have been removed for a number of bundles in the Karaf enterprise features. In principle a good idea (sometimes start levels are even seen as anti-pattern in OSGi). However, sometimes I now face the issue that the transaction service is missing when one of my persistence
