I have the same problem, I want to split the content of a text file to
others messages and send then to a queue. What is the type tu return with
evaluate() method.
from("file:insert_request.sql").splitter(new Expression<Exchange>()
{
public Object evaluate(Exchange exchange)
{
return exchange.getIn().getBody(String.class).split("\n");
}
}).to("jdbc:dataSource");
