Re: Cayenne 4.0 M2 and OSGi classloading issue

Hi Andrus, 
sorry for my late reply. And thanks for your comments.

Do you have any suggestion on how can I move forward in the short term? 

I mean, shall I try a different pooling technology (as you did, if I
understood properly)?
In that case, do you mind to point me to an example or write me few lines
how to have Cayenne running with this other pooling library?

Thank you again,
Matteo

And BTW, over the weekend I committed a new connection pool to Cayenne that is non-blocking and supports connection validation query. So  barring any possible bugs in this new code, it should be on par with more "high-end" pools in performance and failover. So you might just build M3 from master and use the example as is.

Our example on GitHub should work with built-in Cayenne connection pool:

ServerRuntime runtime = new ServerRuntimeBuilder()
	.addConfig("cayenne-project.xml")
	.addModule(OsgiModuleBuilder
		.forProject(Activator.class)
		.withDriver(org.apache.derby.jdbc.Driver42.class)
		.module())
	.build();


I suspect it should also work with older DBCP 1 pool, if you could get this into OSGi. But this hasn't been tested.
