jdbc and ClassNotFoundException

Hi,

sometimes on my version of WebViewer there appeares exception something about ClassNotFoundException of com.jdbc...TimeUtil

I found it could be because of two libraries of jdbc connector in application. I have two, the first in WEB-INF/lib and the second in WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbcxxxxx. Both have the same version.

I tried to delete library in platform/plugin directory. WebViewer works. Reports are reported. Do you think is it correct?

In BIRT 3.7 this is not an issue you just put the driver in the web-inf/lib directory or the in the cp of your app server. In BIRT 2.6.2 and lower it needs to be in the plugins directory unless you add a key to the app context pointing to the driver. For example add this script to the beforeOpen event of the datasource.

reportContext.getAppContext().put("OdaJDBCDriverClassPath","locationofdriver.jar");

If it is working without this maybe the parent classloader of the report engine is picking it up.
