Expand Up @@ -61,26 +61,25 @@ To allow Quartz to see classes the Clojure compiler generates, we must provide a
custom implementation of the ClassLoadHelper class which Quartz uses for
discovering classes. A working implementation is below:

``` java
// Example package
package oceania.myservice.quartz;
```clj
;; example namespace
(ns oceania.myservice.quartz.DynamicClassLoadHelper
(:gen-class
:extends clojure.lang.DynamicClassLoader
:exposes-methods {loadClass superLoadClass}
:implements [org.quartz.spi.ClassLoadHelper]))

import clojure.lang.DynamicClassLoader;
import org.quartz.spi.ClassLoadHelper;
(defn -initialize [_])

public class DynamicClassLoadHelper extends DynamicClassLoader implements ClassLoadHelper {
public void initialize() {}
(defn -loadClass
([^oceania.myservice.quartz.DynamicClassLoadHelper this, ^String class-name]
(.superLoadClass this class-name true)) ; loadClass(String name, boolean resolve)
([^oceania.myservice.quartz.DynamicClassLoadHelper this, ^String class-name, _]
(.superLoadClass this class-name true)))

@SuppressWarnings("unchecked")
public <T> Class<? extends T> loadClass(String name, Class<T> clazz)
throws ClassNotFoundException {
return (Class<? extends T>) loadClass(name);
}
(defn -getClassLoader [this]
this)

public ClassLoader getClassLoader() {
return this;
}
}
