Subject [jira] Commented: (CAMEL-930) file expression language, file-producer: date and bean expressions should be possible without the need to have a FileExchange
Date Thu, 25 Sep 2008 09:59:52 GMT

Claus Ibsen commented on CAMEL-930:
-----------------------------------

TODO: bean language as ${bean:MyBean} should be able to be used just as .bean(MyBeanClass.class}
= just giving the classname and Camel will instantiate it automatically.

> file expression language, file-producer: date and bean expressions should be possible
without the need to have a FileExchange

>    Affects Versions: 1.5.0
>         Environment: Windows XP, JDK 5, Apache Camel Snapshot

> the file expression language , file-producer: date and bean expressions are very usefull,
but works only with a FileExchange.
> example:
>    from("sftp://user@host//path?password=password&consumer.setNames=true").
>   .setHeader(FileComponent.HEADER_FILE_NAME, file("${date:now:yyyyMMMdd}.out"))
>    to("file://output_dir");
> The above code will result in a ClassCastException, because the file expresssion language
relies on having a FileExchange.
> Proposal: 
> - move the date:now and bean: expression from file to simple
> - let sftp send FileExchange, rather than DefaultExchange
> - let the file expression language work with DefaultExchange (use header-entries instead
of FileExchange.getFile())
> With best regards, Dario
