org.eclipse.gemini.dbaccess.derby bundle does not start [message #1426130]

Hello there,

I am strggling to have the sample come with Gemini JPA DBaccess working in a standalone Equinox LunaRC4 runtime.

The org.eclipse.gemini.dbaccess.samples started fine; but both "org.eclipse.gemini.dbaccess.derby" and "org.eclipse.gemini.dbaccess.util" bundle stay in "Starting" state (due to a lazy start). That means no DataSourceFactory is registered. What have I missed here? should I register my own DataSourceFactory?

I have Gemini JPA 1.1, EclipaseLink 2.4.2, osgi.enterprise installed and started ...

Thanks a lot,
David

Have you set org.eclipse.gemini.dbaccess.derby to autostart=true.

No bundle has a dependency to the dbaccess.derby bundle to avoid dependencies to a database vendor in the code. Therefore the dbaccess.derby bundle won't be started if not set to autostart.
The Derby Driver is registered by the dbaccess.derby bundle in its Activator. If the Activator runs it registers the DataSourceFactory.

Thanks a lot!

However, now I see this error (there is not stack trace printed from sample). org.apache.derby bundle is started; and the connection string is "jdbc:derby:testDB;create=true". ... Have you seen this before?

What does the stacktrace say? I would assume that the database cannot be created in the current directory. Change the JDBC_URL in DataSourceClientExample.class to e.g. "jdbc:derby:/c/temp/testDB;create=true"

Thanks again!! I wrote my own service tracker to configure the DataSource to a network derby; and it connected. Big step.

Now I want to have the "org.eclipse.gemini.jpa.sample.basic-1.1.0" sample come with gemini-jpa-1.1.0 to work on Derby. Following the guide, I installed and started "org.eclipse.gemini.jpa.sample.basic-1.1.0.RELEASE.jar"; but I got same NoClassDefFoundError as mentioned in this question "https://www.eclipse.org/forums/index.php/t/813770/". (I had the earlier error when trying on a PostgreSQL).

Have you seen this error before? or I missed some steps? ... thanks a lot!!

I just installed 3 org.eclipse.gemini.jpa.sample.configadmin jars. Started them in this order, configadmin.pu -> configadmin -> configadmin.gen. I got same NoClassDefFoundError. Following is the stack trace ... Have someone seen this before? thanks!!!

Hey guys, I'm struggling with the same issue. When I run my RCP application, my bundles' statuses are not as expected:

135	STARTING    org.eclipse.gemini.dbaccess.h2_1.1.0.RELEASE
136	STARTING    org.eclipse.gemini.dbaccess.util_1.1.0.RELEASE
137	RESOLVED    org.eclipse.gemini.jpa_1.2.0.M1
155	RESOLVED    org.h2_1.3.176

I also tried to enable auto start for them in my product file, but no success:

      <plugin id="org.eclipse.gemini.dbaccess.h2" autoStart="true" startLevel="0" />
      <plugin id="org.eclipse.gemini.dbaccess.util" autoStart="true" startLevel="0" />
      <plugin id="org.eclipse.gemini.jpa" autoStart="true" startLevel="0" />

If I manually start them using Eclipse's built-in OSGi console, everything works properly. What am I missing here?

Also, I'd like to make the EntityManagerFactory service available through DS, but this is not working either. Is there any other way without using the service lookup approach from the examples?

Thanks in advance.

Actually, if I start manually only the org.eclipse.gemini.jpa_1.2.0.M1 bundle, it works. What do I need to do to make it start automatically when I run my product?

Hi,

I've got the following start levels in my application (and it works):

<plugin id="javax.persistence" autoStart="true" startLevel="1" />
<plugin id="org.eclipse.equinox.ds" autoStart="true" startLevel="0" />
<plugin id="org.eclipse.gemini.blueprint.extender" autoStart="true" startLevel="3" />
<plugin id="org.eclipse.gemini.jpa" autoStart="true" startLevel="3" />
<plugin id="org.h2" autoStart="true" startLevel="1" />

Hope this helps.
Regards Sebastian

Hello Sebastian.

Thanks for the code snippet. I tried the same start levels, but still no success. I suspect that I'm missing something in Eclipse. In my Run Configuration, if I don't use features and set the plug-ins' start levels individually, it works fine. Have you ever tried this using features?

Cheers,
