string constants in simple expression language
Is there a way to use string constants in the simple expression language. I
am trying to fix a deprecation warning in:
from("direct:saveAgentsFile")
.setHeader(FileComponent.HEADER_FILE_NAME, "agents.xml")
.to("file:///Users/streekgj/Desktop/filestore/?append=false")
;
I tried to change it to:
.setHeader(FileComponent.HEADER_FILE_NAME, new
SimpleExpression("agents.xml");)
Of course it is treated as an expression, but is there any way to mark it as
an string literal, or escape the dot? Something like:
.setHeader(FileComponent.HEADER_FILE_NAME, new
SimpleExpression("'agents.xml'");)
or
.setHeader(FileComponent.HEADER_FILE_NAME, new
SimpleExpression("agents\\.xml");)
Or do string literals only works with operations?

The deprecation is in using setHeader with a String as the second argument:
.setHeader(FileComponent.HEADER_FILE_NAME, "agents.xml")
And indeed Willems suggestion fixes the warning:
.setHeader(FileComponent.HEADER_FILE_NAME, constant("agents.xml"))

Hi
You could use constant for this, just like this
from("direct:start").
setHeader("foo", constant("ABC")).
to("mock:result");
