Re[2]: Using camel-main, xml route, referencing a java class as processor

Mon, 17 Jan 2022 21:12:52 -0800 

I am trying with Camel 3.14.0.

While debugging I noticed that

call gets to ProcessReifier.java

 public Processor createProcessor() {
Processor answer = ((ProcessDefinition)this.definition).getProcessor(); 
        if (answer == null) {
ObjectHelper.notNull(((ProcessDefinition)this.definition).getRef(), "ref", this.definition); answer = (Processor)this.mandatoryLookup(((ProcessDefinition)this.definition).getRef(), Processor.class); 
        }

at that point - variables are as below:
definition = {ProcessDefinition@3684} "process[ref:#class:org.myorg.camel.MyProcessor]" 
 ref = "#class:org.myorg.camel.MyProcessor"
 processor = null
 log = {Logger@3741} "Logger[org.apache.camel.model.ProcessDefinition]"
 inheritErrorHandler = null
 blocks = {LinkedList@3742}  size = 0
parent = {RouteDefinition@3358} "Route(route1)[From[timer://foo?fixedRate=true&period=60000] -> [SetBody[simple{Hello}], process[ref:#class:org.myorg.camel.MyProcessor], To[log:hello]]]" 
 interceptStrategies = {ArrayList@3743}  size = 0
 index = 2
 id = "process1"
 customId = null
 description = null
((ProcessDefinition)this.definition).getProcessor() , returns null and then it performs a lookup on registry. 

It never seemed to get to
public Object lookupByName(String name) {
        if (name != null && name.startsWith("#class:")) {
            return this.createBean(name, Object.class);
        } else {
return name != null && name.startsWith("#type:") ? this.lookupBean(name, Object.class) : this.getRegistry().lookupByName(name); 
        }
    }
if it may have - it may have identified that the class starts with #class: and needs to be bypassing registry.

What camel version do you use

 Hello,
 I have a scenario where I am using camel-main with XML Route and a Java
 Class as a Processor.

 It gives me following error:

 Example Code is described:
https://github.com/chiragsanghavi/camel-experiments/tree/main/processor

 Basically referring to processor using <process
 ref="#class:org.myorg.camel.MyProcessor"/> in route directly as described
 in
https://camel.apache.org/manual/processor.html#_referring_to_beans_using_class_syntax
 .

 But it doesn't seem to work.

 Are there any other conditions to using #class ?
