Multiple constructors in jruby

Ruby JRuby

Hallo all,

I’m in need to re-implement this bean in jruby:

package camelinaction;

import org.apache.camel.CamelContext;
import org.apache.camel.ProducerTemplate;

public class OrderStatusBean {

private ProducerTemplate template;

public OrderStatusBean() {
}

public OrderStatusBean(CamelContext context) {
    setTemplate(context.createProducerTemplate());
}

public void setTemplate(ProducerTemplate template) {
    this.template = template;
}

}

Well: the problem is with the overloaded constructor. No problem if I
don’t need the CamelContext (just leave only the no-params constructor).

But when I need to receive the CamelContext I stumble in this problem:
if I omit the no-params constructor camel complains the lack of the
defaults constructor:

Caused by: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name ‘epiReplicaQuery’ defined in file
[/homel/francesco/sviluppo/camel/epiReplicaPeriodic/target/classes/META-INF/spring/camel-context.xml]:
Instantiation of bean failed; nested exception is
org.springframework.beans.BeanInstantiationException: Could not
instantiate bean class [it.unimore.cesia.EpiReplicaQuery]: No default
constructor found; nested exception is java.lang.NoSuchMethodException:
it.unimore.cesia.EpiReplicaQuery.()

My (non working) translation in jruby is:

require ‘java’

java_import “org.apache.camel.ProducerTemplate”
java_import “org.apache.camel.CamelContext”
java_import “org.slf4j.Logger”
java_import “org.slf4j.LoggerFactory”
java_import “ch.qos.logback.classic.LoggerContext”

java_package “camelinaction”

class OrderStatusBean
def initialize(context)
@template = context.createProducerTemplate
@logger =
LoggerFactory.getLogger(“it.unimore.cesia.#{File.basename(FILE,
“.rb”)}”)
@logger.info(“Hello from #{FILE}.”)
end

def send_msg
@logger.info(“Sent mesg”)
@template.sendBody(“this is a test”);
end
end

Thank you for your help,

Francesco
