It is sorta covered in the JavaRanch Style Guide. And what is this jar that I’m com.myssl.jdbc.driver in and why is there very little documentation about it?

This is why I was forced to use datasources rather than drivermanagers in the first place. Error while initializing the default tenant. Can you share them? BasicDataSourceFactory Submitted by mark. Unexpected exception resolving reference java.
As I mentioned elsewhere I ran into a thread where the solution to this exact issue was “upgrade the jdk” and it worked for everyone in the thread.
I don’t think this is it, but it might be worth a shot, when you OP copied in the jar, did you to chown it to tomcat: Cannot resolve reference to bean ‘persistenceService’ while setting constructor argument ; nested exception is org.
[SOLVED] Get Java Error ‘Unable to create initial connections of pool’ during startup
Cannot resolve reference to bean ‘sequenceManager’ while setting failer argument ; nested exception is org. I am currently using eclipse and I have two folders in my workspace.
On what platform are you? I tried with the settings below and still get no where. So while I can’t say if it will work com.mysql.jrbc.driver you, it might be worth a try. Furthermore, this causes issues because tomcat wants to load jdbc drivers from a place where it can share them between running apps.
But when I use the below code snippet to obtain data source, I still get the error.
Here is where I am now. I’ve got class right now and I’ve not had a chance to work on this since javax.aming.namingexception yesterday. Basically, tomcat can’t establish a connection to the database because you dont have the proper driver in the classpath. I have jconsole working, but I don’t see anything related to proxool.
