[jira] [Created] (DBCP-363) dbcp bundle should use DynamicImport
dbcp bundle should use DynamicImport
------------------------------------
Key: DBCP-363
URL: https://issues.apache.org/jira/browse/DBCP-363
Project: Commons Dbcp
Issue Type: Bug
Affects Versions: 1.4, 1.3
Reporter: Felix Mayerhuber
The bundle provided in the maven central of the commons.dbcp doesn't have a DynamicImport defined. This resolves in following error:
If you want to use a BasicDataSource class as dataSource and the class is provided by the osgi environment (equinox, ...) the dataSource is not able to be created due to a ClassNotFoundException. If the bundle would have set DynamicImport it works. (I had to change from your bundle to the commons.dbcp bundle provided by servicemix, because there the DynamicImport is set)

[jira] [Commented] (DBCP-363) dbcp bundle should use DynamicImport

Holger Hoffstätte commented on DBCP-363:
----------------------------------------
The whole purpose of OSGi is to *prevent* the kind of unfettered access and more or less random class wiring established by DynamicImport; it's a bad practice that should die out. Instead of letting dbcp blindly create instances the right thing to do would be use proper OSGi lookup of a DataSource through an OSGi-aware factory.

[jira] [Commented] (DBCP-363) dbcp bundle should use DynamicImport

Jukka Zitting commented on DBCP-363:
------------------------------------
Having DynamicImport in place does not prevent DBCP from also using the DataSourceFactory mechanism in OSGi.
Meanwhile defining DynamicImport for DBCP does solve the problem for cases where the JDBC driver exports the relevant driver classes but does not (yet) implement a DataSourceFactory service.
