How to send a http request to a non java appln

I have one legacy web application running which can handle only http request . So I need to connect (using http request) and send my request and get the response, without opening that application in browser.
Any idea
1) How to connect to non - java appln from a java appln ?
2) How to use the Httprequest without displaying the page using browser?

You can try one of three routes:
Open a socket and write the HTTP request and parse the HTTP response yourself
Use java.net.URLConnection
Use Jakarta Common's HttpClient at jakarta.apache.org- Saish

How to send a https request using jsf

hi
Can anybody tell a sample how to send a https request using JSF ...
thanks

Prefix the request URI with the https protocol.
The answer is too easy and straightforward that I guess that you mean something else. If you just want to know how to configure an SSL environment for your own webapplication, refer to the Java EE tutorial chapter 28: http://java.sun.com/javaee/5/docs/tutorial/doc/

How to pass a HTTP request from a simple java class

Is it possible to pass an HTTP request from a simple java class.if yes how?

Is it possible to pass an HTTP request from a simple
java class.if yes how?If you're talking about creating a HttpRequest object and passing it to a servlet, that would be a red flag to me that your design is flawed. You shouldn't have to do that - the application server (Tomcat, Weblogic, etc) should be the only thing that has to worry about creating that kind of object and passing it to you.

You can invoke BAM Webservices (Using Oracle BAM Web Services) or use JMS integration using Enterprise Message Sources (http://docs.oracle.com/cd/E17904_01/integration.1111/e10224/bam_ent_msg_sources.htm)

How to send sms to mobile from tomcatserver using java code?

Hi,
Could you please let me know that,
How to send sms to mobile from tomcatserver using java code? Please provide the code snippet.
Thanks in advance.

Yes, but something needs to send that message. You can't just take an arbitrary computer and send an SMS, it does not have the hardware to do that.
So either you have a mobile through which you do that or more likely - you use some sort of online service to do it. Whatever choice you make will determine what code you will have to write to get it done. Nobody is going to deliver the code to you, that's your job. It is also your job to figure out what service you are going to use.
