Method execution problem in java

[Elizabeth Allen]

Hello,
I have a problem of inheritance which disturbs me because it challenges one from my understanding of java, I hope someone will give me an explanation. Within my team, we have a framework based on which several applications depend, a class is abstract, and each application must be classified under this class. The method getApplicationName () returns normally the application name, defined in a configuration file. So now I have something that works but is ugly, and I do not understand why the simple version does not work. If someone has an explanation. Any help on this is highly appreciated. Thanks in advance.

Hello,
See if the following code helps you. Here is the code that I have created check out if it helps.

Public String appnm() {
	return approp().getName();
}
 
Protected static ApplicationProperties approp(){
		
	if (proper == null){
		WebApplicationContext cnt = WebApplicationContextUtils.getWebApplicationContext(ServletContext);
proper = ApplicationProperties)cnt.getBean("proper");
	}
	return proper;
}

Hello,
This is my updated code, have a look at it

abstcnt ctx = abstcntt.getCurrentContext(request);
ctx.getapp();

And I use this

appcnt ctx =(appcnt)abstcnt.getCurrentContext(request);
ctx.getApplicationName();

And also this
abstcnt tmpCtx = abstcnt.getCurrentContext(request);
Method mth = Class.Class.forName(tmpCtx.getClass().getName()).getMethod("getApplicationName", null);
out.print(mth.invoke(tmpCtx, null));

Hello,
Please check the following code I have modified it, see if this works now.

<% = abstcnt.getCurrentContext(request).getApplicationName()%>
--
<%
abstcnt tpcx = abstcnt.getCurrentContext(request);
Method mth = Class.Class.forName(tpcx.getClass().getName()).getMethod("getApplicationName", null);
out.print(mth.invoke(tpcx, null));
%>

Hello,
In my opinion on your application server you are always the old version of the superclass, ie one where getapp() is static and the new version of the subclass which contains an instance method getapp(). So when you compile the following code:

abstcnt.getCurrentContext(request).getapp()

The compiler sees only the superclass, and as for his method getapp() is static. It generates a call to the static method (and thus without inheritance mechanism).

Hello,
I think the getapp() was static at the parent class, the name of the application was the same for all users of an application. Now, you removed the static level of the superclass, thus redefining the method in subclasses. Each user can have a different application name, as it is stored in context, which is related to the session. I think you get the point I am trying to explain here.
