Could Not Load Jdbc Driver Class Org.apache.derby.jdbc.clientdriver
It would be nice to borrow this trick if it isn't hard to implement. If it needs to by synchronized then the "200th" threadwill be in a long line-up which is why I would see the need to createseveral pooled ObjectContexts. What are the discontinued functionalities between SharePoint 2013 and SharePoint 2016? Now I'm getting confused and perhapsI'm using incorrect terminology.In my mind there is the actual connection to the database as definedduring the creation of the DataContext. navigate here

In all three cases, Tomcat/Jetty/etc could still be part of the solution.I'm a little confused by this email thread because it started off as questions about derby and then morphed into internet Not the answer you're looking for? In these scenarios, you don't need the container for its high-concurrency guarantees.Of course that doesn't mean that a container would necessarily be useless in such scenarios.

But then this takes be back toconnection pooling as defined in the Modeller. check over here You can find this jar in the download package of derby from here. I'd probably look up the Cayenne docs on connection pooling, and just make sure that everything is configured explicitly that the web container would do for you implicitly.

Standalone apps tend to work by opening a single Connection and using that for all requests. I'm sure the database administrator won't like to see my app opening and closing connections to their database so I would prefer to open up a pool of connections and then Ari On 30/04/12 7:37pm, Tadrierion wrote: > Sorry for double post : how I'm suppsoe to do that* > > -- > View this message in context: http://cayenne.195.n3.nabble.com/Can-not-load-JDBC-driver-named-org-apache-derby-jdbc-ClientDriver-tp3950272p3950324.html> Sent from the Killing off a character When I lose concentration while levitating, do I fall?

Since I'm still stuck with Hibernate, I can't advise very well about how to best integrate a connection pooling library and Cayenne. Is a stealth torpedo possible? I reread your question and I see that you have it working in the modeler but want to make it work with your Jetty application.

What is the meaning of *sides* in this conversation? In “a so-called "HPACK Bomb" attack”, if "so-called" is not sarcasm then what is it? A container enforces a design that makes retrying transactions easier, a connection pool ensures that that broken connections will be recreated ASAP. So you have some sources and libraries that are assembled into a .war file.
I have created a database and I have generated classes thanks to Cayenne. That's the use case for containers and connection pooling.If high concurrency is not an issue, you could have just a handful of Swing application banging on the same database, or even Check Meziane answer below. –pshemek Apr 30 '15 at 10:08 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote accepted You need just to use derbyclient Related questions exporting multi select checkbox field value using work-item export Moved/renamed file appears as 'deleted' in Pending Changes.
