Hello All,
I am new to the Camel world and need some help on creating expressions. I
have the following route defined using Java DSL.
from("direct:jde")
.setHeader("FMZ57FMR", simple("${body.fuelDistribution.quantity}"))
.setHeader("FMZ57ST", simple("${body.fuelDistribution.sourceTank.state}"))
.setHeader("FMZ57JOB", constant(null))
.setHeader("FMZ57MISC1",
DateUtility.convertDateToKRC("${date:now:yyyy-MM-dd}"))
.setHeader("FMZ57MISC2", simple("${date:now:yyyy-MM-dd}"))
.to("sql:" + insertStmt.replaceAll("\t", " ") + "?dataSource=exampleds");
I have two questions.
1. How do I make DateUtility.convertDateToKRC("${date:now:yyyy-MM-dd}") into
an Expression as required by the setHeader method. DateUtility is a Java
class with static method convertDateToKRC. The method takes one string
argument. The compiler is giving me the following error:
The method setHeader(String, Expression) in the type
ProcessorDefinition<RouteDefinition> is not applicable for the arguments
(String, int) InsertReadings.java
/LogPublish/src/main/java/FuelLog/LogPublish line 33 Java Problem
2. Is there an alternative to the expression:
simple("${body.fuelDistribution.sourceTank.state}")
Specifically I am looking for the cleanest way to retrieve items several
levels deep from a Java object in the body of the message.
Thanks for your help.
