Claus Ibsen reassigned CAMEL-4308: ---------------------------------- Assignee: Claus Ibsen > commons-dbcp bundle used in camel feature.xml doesn't allow dynamic imports > --------------------------------------------------------------------------- > > Key: CAMEL-4308 > URL: https://issues.apache.org/jira/browse/CAMEL-4308 > Project: Camel > Issue Type: Improvement > Reporter: Freeman Fang > Assignee: Claus Ibsen > Attachments: CAMEL-4308.patch > > > currently the commons-dbcp bundle used in camel feature.xml doesn't allow > dynamic imports, it will cause exception like > org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver class > 'oracle.jdbc.driver.OracleDriver' > as > JDBC driver class not found actually is a common issue in OSGi container, > this problem generally from a bundle(let's say it bundle A, commons-dbcp in > this case) using some code like classForName(jdbc_driver_classname) to init a > jdbc driver class, this is a big problem in OSGi world, as if BundleA not > import package for jdbc_driver_classname, we'll see the problem. However > BundleA actually can't know about package name for jdbc_driver_classname > beforehand, as the jdbc_driver_classname generally is passed in through > configuration during runtime, it can't be determined during build time, so we > can't add correct package import when we generate bundle A. > The general solution is > 1. add dynamic import for bundle A(commons-dbcp) > or > 2. create JDBC driver as a fragment bundle, and attach it to bundle A(bundle > A is host bundle now), so that all resource from fragment bundle is available > for the host bundle. > Solution 1 left less effort for end user and n servicemix wrapped > commons-dbcp bundle we already have dynamic-import header and I think camel > features should use the servicemix wrapped commons-dbcp bundle as well. > I will append a patch soon. -- This message is automatically generated by JIRA.
