Hi Team,
I am unable to access my webapp directly from from external browser and remote system, i am able to access the same in eclipse default browser,

http://localhost:8080/AutomationReports/
but i can access some pages by passing url from the browser to the servlet as follows: http://localhost:8080/AutomationReports/report?reportButton=report1, it will navigate to expected page
but i am unable to access some fully loaded pages even passing url from browser to the servlet as follows: http://localhost:8080/AutomationReports/report?reportButton=ViewAllReports

can you please guide me what are the settings i need to do to access my application globally.

I will attach my codes and server.xml, can you please have a look.

Thanks & Regards
Reddy

Please use the "Code" tags to wrap samples of Java code, XML, and other pre-formatted data. It's much easier to read that way. The message editor "Code" button can insert them.

J2EE webapps do not know or care* whether the URL request was made from the local machine or a remote machine. The only difference is that if you don't have your firewall open, the network itself will block remote machines from passing requests into the Tomcat server for processing.

Likewise, the only difference between making a web request using a stand-alone web client such as Internet Explorer or Firefox and the Eclipse built-in browser is that the Eclipse built-in browser may not have all of the features that the stand-alone browsers do.

So there's nothing you should set in either the server.xml file or the WAR to control local/remote request handling.


---
*A webapp can be "made to care" where requests came from if the program logic decides to look at incoming URL header information. But that doesn't affect request routing - it's just whatever user code wants to do once the request comes in.
