javaflow problem

[Carlos Maté <cm...@gmail.com>]

Hi.
I'm using cocoon 2.1.7. In a javaflow class. I have this code:
*

if
*( getComponent(DataSourceComponent.ROLE + "Selector")*instanceof*
ComponentSelector);


{

ComponentSelector selector = (ComponentSelector) getComponent(
DataSourceComponent.ROLE + "Selector");

}

*But I obtain:*

ERROR (2005-11-16) 09:38.*57*:718 [sitemap.handled-errors]
(/*mysis/**login*.do)
http-8080-Processor25/ErrorHandlerHelper:
java.lang.ClassCastException

*¿How I can obtain a BD connection?*

*In a flowscript I wrote:*

var selector = cocoon.getComponent(Packages.*org*.apache.avalon.excalibur.datasource.DataSourceComponent.ROLE
+ "Selector");
var datasource = selector.select("NameOfPool");
var connection = datasource.getConnection();

*But I don't know how to do this in a java flow.*

*Thanks.*

Your code does not seem wrong, but I don't use javaflow myself.

I would personally use something like:

Object o = getComponent(...)
if (o instanceof ComponentSelector) {
ComponentSelector c = (ComponentSelector) o;
}

Post your complete stacktrace and maybe you will get more info.
