> I have an application in which I am calling a groovy script. The application uses a custom class loader, because I have to load some of jars dynamically, including the jdbc drivers. I am using this class loader in the constructor of GroovyShell(). Here is snippet of my script
> Class.forName("<JDBC driver>");
> connection = DriverManager.getConnection(url,...)
> When I run the script using shell.evaluate(), the driver is registered properly. I know it because, it didn't throw any exception and I have added trace statements in JDK code as well. But when I create the connection it fails with error
> java.sql.SQLException: No suitable driver found for ....
> I listed the registered drivers from DriverManager, it didn't show the jdbc driver I registered earlier. When I debugged the DriverManager, I found that the 'caller' classloader is totally different. It is 'CallSiteClassLoader' which is groovy specific. But the script registered the jdbc driver with the classloader I specified in the groovyShell constructor.
> Groovy should not use its own class loader when I specify a class loader. Or at least it should use my class loader as parent.
