Clause,
This is what my route looks like
from("file:C:/work/esb/filetestpoller/")//large file
exceeding 800M
.convertBodyTo(InputStream.class)
.splitter(customsplitter)//custom splitter(injected by spring)
that
returns a java.util.Collection
.process(requestprocessor)
.to("jms:responseoutbox");
I would prefer the custom splitter return java.util.Iterator instead of a
Collection, the reason why I am returning a collection is because if I
return an iterator I get an exception. The reason I am using a custom
splitter is to return a data structure ( a collection) that gets the data
from a persistent store (much like the claim check pattern) instead of
keeping the data in memory which will crash our system. Please let me know
if there is a better way of dealing with this issue.
