Quartz properties file configuration in web.xml and its location - quartz-scheduler

Question

I tried to resolve the problem of avoid loading default quartz.properties file for long time. Hope someone can give a hand here. Thanks a lot!
Basically, I have read many posts on this problem while their solutions didn't resolve my case. I have placed quartz.properties file under WEB-INF/classes and following are my configurations in web.xml by using context listener:
<context-param>
<param-name>quartz:config-file</param-name>
<param-value>quartz.properties</param-value>
</context-param>
<context-param>
<param-name>quartz:shutdown-on-unload</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>quartz:wait-on-shutdown</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>quartz:start-on-load</param-name>
<param-value>true</param-value>
</context-param>
<listener>
<listener-class>
org.quartz.ee.servlet.QuartzInitializerListener
</listener-class>
</listener>
The results still showed like this:

Another confuse I have is if it was really loading default quartz.properties file, then why are the thread pool and scheduler name were set properly based on my customized quartz.properties file?
Another hand, I also tried to set different path for quartz.properties file based on the official documentation of Quartz: QuartzInitializerListner. For example:
<context-param>
<param-name>quartz:config-file</param-name>
<param-value>/MyProject/WEB-INF/my_quartz.properties</param-value>
</context-param>
The results showed even worse. It would be totally default settings. Hence, I'm quite lost now. Please kindly elaborate the root cause of this scenario. Thank you very much!

I fixed this issue placing the quartz.properties in my resources folder (src/main/resources).
Your context Param should look like this:
<context-param>
<param-name>quartz:config-file</param-name>
<param-value>quartz.properties</param-value>
</context-param>
Take a look to the quartz's code:
InputStream is = null;
Properties props = new Properties();
is = Thread.currentThread().getContextClassLoader().getResourceAsStream(filename);
where filename is the properties file.
So, it tries to get the file as a Stream. Please check the Java Doc:
