passing and getting parameters

[preethi Ayyappan]

Hi,
I am calling one java standalone application from another standalone application like the following

   
Class c=Class.forName("Ivr");
Object obj=c.newInstance();
Ivr h=(Ivr)obj;
h.service(request,channel);
 

I want to pass and get parameters in both the application.Is it possible in standalone application?

Thanks.

Are you running two JVMs?

Do a search on JavaRanch; that sort of question comes up about every two weeks. Lots of possibilities:

You could connect the two together with Sockets.

You could create a class to embody data and serialise its instances from one application and deserialise them into the other application.

You could have a text file with data in, writing and rewriting it from the different applications.

I have a question for you.

Your code obviously recognizes class Ivr. Yet you still use reflection to create an instance. Why?

First of all, why use Class.forName if Ivr is available; therefore Ivr.class is also available. That will return the same as Class.forName("Ivr").

Second of all, why not say

Ivr h = new Ivr();
h.service(request,channel); 

That's a) a lot better to read, and b) faster.
