Re: Karaf 4.0.3 & JPA

Mon, 30 Nov 2015 11:17:56 -0800

FWIW, I rebundled OpenJPA with the javax.transaction/javax.transaction-api/1.2 dependency & I am now able to successfully connect to the database. 

Thanks again,
Jason

Ah .. sorry forgot that you use openjpa. This might be difficult as openjpa is incompatible to jta 1.2 which the transaction.blueprint 2.0.0 requires. In this case you will probably need to create your own transaction feature that skips the 2.0.0 version and only relies on jta 1.1.
I guess because of openjpa karaf installed jta 1.1 and 1.2. Unfortunately it does not work to install both.
Another option would be to rebundle openjpa as in fact it is compatible to jta 1.2 and only the import package version range is too small. As the openjpa guys have still not fixed this I wonder if we should even do the rebundling at karaf or servicemix. On the other hand I still hope that they fix this.

I gave that a whirl...specifically, I changed the bootFeatures to the following:

Upon startup of the custom distro, I see the following from a list command:

There is an exception in the karaf.log:

However, the transaction packages are visible:

Thanks Christian,
Then in the pom.xml for building the custom distribution, I have the following relevant bootFeatures: 

        <feature>aries-blueprint</feature>

        <feature>cxf</feature>

        <feature>jdbc</feature>

        <feature>transaction-api/1.1.0</feature>
This is wrong. You need to install the "transaction" feature. This is just the API. Also for transaction you do not need to specify a version. The feature will install the old and the new transaction blueprint bundle. 



        <feature>jpa/1.0.4</feature>
Also not sure about this one. As you use the annotations there you could as well install the "jpa" feature which will give you the new 2.x version. 

<feature>openjpa/${openjpa.version}</feature>
