Method with name: sayHi not found on bean - Using apache Camel - apache-camel

Question

I am using apache camel to communicate to a remote EJB which is deployed in Weblogic Server 12c. when i invoke remote EJB it throws me the below exception
org.apache.camel.component.bean.MethodNotFoundException: Method with name: sayHi not found on bean: ClusterableRemoteRef(3961905123449960886S:192.168.1.98:[7001,7001,-1,-1,-1,-1,-1]:weblogic:AdminServer [3961905123449960886S:192.168.1.98:[7001,7001,-1,-1,-1,-1,-1]:weblogic:AdminServer/394])/394 of type: com.iexceed.study.HelloRemoteEJBImpl_6zix6y_IHelloRemoteEJBImpl_12120_WLStub. Exchange[Message: [Body is null]]
My Came-context.xml file is as below
<bean id="ejb" class="org.apache.camel.component.ejb.EjbComponent">
<property name="properties" ref="jndiProperties" />
</bean>
<util:properties id="jndiProperties">
<prop key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop key="java.naming.provider.url">t3://IPADDRESS:PORT</prop>
<prop key="java.naming.security.principal">weblogic</prop>
<prop key="java.naming.security.credentials">Weblogic#01</prop>
</util:properties>
<camelContext id="camelclient" xmlns="http://camel.apache.org/schema/spring">
<template id="template" />
<endpoint id="camelejb" uri="ejb:EJBRemoteModule-1_0-SNAPSHOTEJBRemoteModule-1_0-SNAPSHOT_jarHelloRemoteEJBImpl_IHelloRemoteEJB?method=sayHi"/>
<route>
<from uri="direct:start_0" />
<to uri="camelejb" />
</route>
</camelContext>
and the java client class which i am using is
public void postRequest(){
try {
String camelID = "camelejb";
Exchange exchange = null;
Message msg = null;
getCamelContext();
springCamelContext.start();
System.out.println("Starting camel context.....");
getUriMap();
ProducerTemplate template = springCamelContext.createProducerTemplate();
System.out.println("camelejb::::::" + getUriMap().get("camelejb"));
exchange = template.request(getUriMap().get(camelID), new Processor() {
public void process(Exchange exchng) throws Exception {
exchng.getIn().setBody("");
}
});
System.out.println("Exception:" + exchange.getException());
exchange.getException().printStackTrace();
msg = exchange.getOut();
System.out.println("Message:" + msg);
springCamelContext.stop();
System.out.println("Stopping Camel Context....");
} catch (Exception ex) {
ex.printStackTrace();
}
}
EJB :
#Remote
public interface IHelloRemoteEJB {
public void sayHello(String name);
public void sayHi();
}
Having no clue why this error is thrown when the method is available in my EJB.
Will be really grateful from heart because i am already in soup.

What's the result of below code?
getUriMap().get("camelejb")
If you want to reference an endpoint in the camel route, you should do like this
<endpoint id="endpoint1" uri="direct:start"/>
<endpoint id="endpoint2" uri="mock:end"/>
<route>
<from ref="endpoint1"/>
<to uri="ref:endpoint2"/>
</route>
