Hello camel community,
I found my soluation in the language component
(http://camel.apache.org/language.html) after doing some more research.
My routes is now:
<route id="test-javascript">
<from uri="timer://runOnce?repeatCount=1&delay=1000"/>
<log message="test bericht van de ronny" loggingLevel="INFO"/>
<setBody><constant>dit is een test bericht van Ronny
Aerts</constant></setBody>
<to
uri="language://javascript:classpath:test-javascript.js?transform=false" />
<to uri="log:javascript?showAll=true"/>
</route>
And the javascript content is:
var content = request.getBody().toString().toUpperCase();
if (content.match("^UN[AB][+]{1}.*") != null) {
request.setHeader("datatype", "edifact");
} else {
request.setHeader("datatype", "xml");
}
java.lang.System.out.println ("Dit is output vanuit de javascript");
java.lang.System.out.println ("Komt de 2de lijn na de eerste?");
var logger = org.slf4j.LoggerFactory.getLogger(exchange.getFromRouteId());
logger.info ("test logging");
logger.info ("Camel Name {}", camelContext.getName());
logger.info("Camel Status {}", camelContext.getStatus().toString());
logger.info ("Camel Uptime {}", camelContext.getUptime());
logger.info ("Camel Version {}", camelContext.getVersion());
logger.info ("FromRouteId {}", exchange.getFromRouteId());
logger.info ("ExchangeId {}", exchange.getExchangeId());
logger.info ("FromEndpointUri {}", exchange.getFromEndpoint().getEndpointUri());
context.getWriter().println("output from script context");
properties = exchange.getProperties();
if (properties.size() > 0) {
logger.info("there are {} properties in the exchange", properties.size());
propertyNames = properties.keySet().iterator();
while (propertyNames.hasNext()) {
propertyName = propertyNames.next();
propertyValue = properties.get(propertyName);
logger.info ("exchange property '{}' has value '{}' of type '{}'",
propertyName, propertyValue, propertyValue.getClass().getName());
}
} else {
logger.warn("the exchange does not have any properties!");
}
headers = request.getHeaders();
if (headers.size() > 0) {
logger.info("there are {} headers in the message", headers.size());
headerNames = headers.keySet().iterator();
while (headerNames.hasNext()) {
headerName = headerNames.next();
headerValue = headers.get(headerName);
logger.info ("msg header '{}' has value '{}' of type '{}'", headerName,
headerValue, headerValue.getClass().getName());
}
} else {
logger.warn("the message does not have any headers!");
}
This proceduces:

Subject: looking for a way to run javascript in camel and set message headers
Hello camel community,
I'm trying to figure it a way to run a real javascript procedures in camel as
an alternative to use java code out of a bean.
My company is using camel routes from a spring dsl xml file and we would like
to minimize our java coding effort. I know that javascript can be used in
expressions, filters, ... but I can't figure out to more with it like:
<route>
<javaScript>
var content =
request.getBody().toString().toUpperCase();
if (match("^UN[AB][+]{1}.*") != null) {
request.headers.set("datatype", "edifact"); } else {
request.headers.set("datatype", "xml"); }
</javaScript>
</route>
Please don't comment on the content of the javascript because this is just a
very simple example. Things that I surely want to do is setting message (and
attachment) headers.
The fact that javascript can be loading from an external file (since camel
2.11) is already of much help.
