Forrest Xia commented on GERONIMO-4222:
---------------------------------------
Results of some tries:
1. Derby ones work
2. PostgreSQL local one works
3. MySQl local one works
However, there are some strange classloader problem when I am trying
application-wide datasource. If the classloader behavior keeps as
default(parent first), then PostgreSQL and MySQL local datasource cannot be
created, and throw an exception as below:
org/tranql/connector/jdbc/AbstractLocalDataSourceMCF.(Ljavax/sql/ConnectionPoolDataSource;Z)V
java.lang.NoSuchMethodError:
org/tranql/connector/jdbc/AbstractLocalDataSourceMCF.(Ljavax/sql/ConnectionPoolDataSource;Z)V
at
org.tranql.connector.postgresql.PGSimpleLocalMCF.(PGSimpleLocalMCF.java:34)
So I add <inverse-classloading/> to the deployment plan and then they work fine!

> I have frequent trouble with my database pool to an AS/400. The database is
> taken down every night for backup, and at least once a week the connection
> pool is unusable after the database comes back up. Restarting the connection
> pool makes everything work again.
> We are new to Geronimo/WAS-CE -- just this one app on one server -- so I
> don't have anything to compare to. However, we have had this same issue with
> a couple 1.x/1.1.x versions before we upgraded to v2. Also, there are
> several WebSphere (full WAS, not WAS-CE) apps that do not have this trouble.
> Configuration Info
> Driver: JTOpen v6.1 (com.ibm.as400.access.AS400JDBCDriver)
> Pool Min Size: 0
> Pool Max Size: 100
> Blocking Timeout: 5000
> Idle Timeout: 15
