Can't connect on first attempt

[TheObserver]

Hello. I’ve got a struts action class that connects to a webservice to pull over some data. I’m accessing the service with the following code in my java class:

[tt]
StringBuffer mySB = new StringBuffer();
String serviceAddress = "

http://myurl.com/mywebservice";

URL myURL = new URL(serviceAddress);
URLConnection conn = myURL.openConnection();

DataInputStream in = new DataInputStream (conn.getInputStream ());
BufferedReader d = new BufferedReader(new InputStreamReader(in));

while(d.ready())
{
mySB.append(d.readLine());
}

String ret = mySB.toString();
[/tt]

When I initially load up the JSP that uses this action class, the data doesn’t show up, and the server logs don’t show any errors. If I refresh the JSP, the data shows up.

Has anyone seen anything like this? I've been unable to find any information to help out. Thanks for your time.

Are you sure the JSP is being loaded the first time, ie, is the class actually being called?

Cheers,
Dian

Try to add the following lines into your jsp.

response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server

// Is there any proxy server prevent your program?
Your program run fine in reading the web page on Tomcat server on localhost.

String serviceAddress = "

http://127.0.0.1/myweb";
