Dynamic header setting

Rate this Message:
Hi guys,
Here's my situation. I'm processing a file and I'm sending an email to tell the user that the file is being processed. I would like to put the file name in the subject of the email but I don't know how to do that. The file name is in the header CamelFileName. Here's how I set the subject of the email without the file name : .setHeader("subject", constant("Starting File processing ")) Any hint ? |

Yeah you can use the "simple" language for that as it can do it a bit dynamic http://camel.apache.org/simple.html You can just insert ${ } placeholders and then the simple language will do the replacing at runtime. .setHeader("subject", simple("Starting File processing of ${header.CamelFileName} and the file is a good file.")) > -- > View this message in context: http://www.nabble.com/Dynamic-header-setting-tp25220559p25220559.html > Sent from the Camel - Users (activemq) mailing list archive at Nabble.com. > > -- Claus Ibsen Apache Camel Committer Open Source Integration: http://fusesource.com Blog: http://davsclaus.blogspot.com/ Twitter: http://twitter.com/davsclaus |

And if you want access to a bit more information about the file you
can use the "File language" which is an extension to the simple language. http://camel.apache.org/file-language.html It offers some other dynamic tokens you can use to get e.g. file length, date etc. On Mon, Aug 31, 2009 at 11:29 AM, Claus Ibsen<claus.ibsen@...> wrote: > On Mon, Aug 31, 2009 at 11:24 AM, Julien D<myrddin22@...> wrote: >> >> Hi guys, >> >> Here's my situation. >> >> I'm processing a file and I'm sending an email to tell the user that the >> file is being processed. >> I would like to put the file name in the subject of the email but I don't >> know how to do that. >> >> The file name is in the header CamelFileName. >> >> Here's how I set the subject of the email without the file name : >> .setHeader("subject", constant("Starting File processing ")) >> >> Any hint ? > > Yeah you can use the "simple" language for that as it can do it a bit dynamic > http://camel.apache.org/simple.html > > You can just insert ${ } placeholders and then the simple language > will do the replacing at runtime. > > .setHeader("subject", simple("Starting File processing of > ${header.CamelFileName} and the file is a good file.")) > > >> -- > >> View this message in context: http://www.nabble.com/Dynamic-header-setting-tp25220559p25220559.html >> Sent from the Camel - Users (activemq) mailing list archive at Nabble.com. >> >> > > > > -- > Claus Ibsen > Apache Camel Committer > > Open Source Integration: http://fusesource.com > Blog: http://davsclaus.blogspot.com/ > Twitter: http://twitter.com/davsclaus > -- Claus Ibsen Apache Camel Committer Open Source Integration: http://fusesource.com Blog: http://davsclaus.blogspot.com/ Twitter: http://twitter.com/davsclaus |

I tried this solution too but it does not compile for me. I'm using camel 2.0-M3.

It's compiling that way finally
.setHeader("subject").simple("Starting File processing ${header.CamelFileName}") Thanks Claus
