I have Two servlets Account and Billing. Account sending string in GET req to Billing and Billing capitalizing the String and sending back via REsponse. Now I want to insert proxy in between whihc is called Billing only so communication is like
Account--->Billing(Proxy)--->Billing  and response should be Billing--->Billing(proxy)...>Account.  Following is code for all servlets

Account.java



Billing.java THIS IS PROXY


Actual BILLING.java

I am receiving output as follows:
200 response from target proxy to Account
Account servlet sending data :abc

capitalizedStringFromBilling in account as response
THIS IS HELLO FROM PROXY FOR WebApp2
200 response from Billing to proxy
ABC
ABC

that means i am not able to forward responce from actual Billing to Account via proxy as nothing is printed after "capitalizedStringFromBilling in account as response"

whats wrong?

If that output is what you see from a call to Account, then that's correct isn't it?

This output is prior to reading the response from the proxy (in Account):

200 response from target proxy to Account
Account servlet sending data :abc


This output is the String literal on line 41 of Account:

capitalizedStringFromBilling in account as response

The rest has come over from the proxy, which is broken down into:

THIS IS HELLO FROM PROXY FOR WebApp2
200 response from Billing to proxy


then:

ABC

which is the out.println call on line 40 of the proxy and:

ABC

which is the out1.println call in the proxy.  Though why you get the writer a second time I don't know.
 
It is sorta covered in the JavaRanch Style Guide.
