Custom File Component

[Gonzalo Vasquez <gv...@altiuz.cl>]

Well, finally I got started on developing a custom File Component for my "fast writing" needs. 

Most of it is working, but I seem to have something wrong as the all exchanges arrive with CamelSplitComplete=true and CamelSplitIndex=0. I'm using the first to know when to close the OutputStream and the Index to know when to open it, but changed this last part to looking in the exchange properties as a workaround, but doesn't work either. 

I supposed that the exchange was stateful, perhaps as an http session, but seems to me that it's a one time only object, similar to an http request object. That would make sense why I'm losing the "fos" property that I store on the exchange. Assuming the later, where in java code should I create the FileOutputStream to keep it useful from exchange to exchange? i.e. different process method invocations (Producer)


What am I missing?

Attached are the java files I wrote and the spring config file with the routes

Thanks!

If you use an custom expression for the splitter, and that implements
Closable, then Camel will invoke that method for you when the splitter
is done. Then you don't need to remember yourself.
