Subject Re: correlationExpression while Aggregating
Date Tue, 08 Nov 2011 18:24:22 GMT
Ebe, what does your bean return?  If its just a String, then just use the
completionSize() like this...

from("direct:start")
.to("bean:myBean")
.aggregate(constant(true), new MyAggregationStrategy()).completionSize(2000)
.to("file:myFile");

If the bean returns a List of Strings, then you can split them, then
aggregate them based on your strategy

from("direct:start")
.to("bean:myBean")  //returns List<String>
.split(body())  //splits into String
.aggregate(constant(true), new MyAggregationStrategy()).completionSize(2000)   
.to("file:myFile");

see this page, http://camel.apache.org/aggregator2.html for more details...
