Error response: "java.io.BufferedReader@69d02b"
Hi,
I am trying the following code and encountered the error mentioned in the subject.This piece of code read a file online and prints its content into a web page. Can any one explain me what is causing it? I think it could be because my buffer is over loaded. if it is so then can some one show me how to crease the buffer size?
or any help will be appreciated.
Thank you.

I see. This is indeed not the way to download a file.
You should not print it as a String to the outputStream, but you should be rather streaming the whole inputStream contents to the outputStream inside a loop. Learn the Java IO basics: [http://google.com/search?q=java+io+tutorial+site:sun.com].
If you rather want to download it as an independent file instead of copying its content inside a HTML response, then rather write a servlet which does the task independently. Here is an example of such a servlet: [http://balusc.blogspot.com/2007/07/fileservlet.html].

Firstly, you have no constructor for your class.
Secondly, you don't seem to have a main method, though this may be because this class is called by another.
Thirdly, don't you have a line number or other identification for what is causing the exception?Thank for your reply=D
Yap this is a class that is called by another class that why there is no main method for it. And for the line that causing the error is
String record = st3.nextToken(" "); -

Hi gurus,

The other interfaces runs well. just one get the the following error:

I check the payload and test in the inbound proxy. on error.
Any hints?

You can use the beans below to overcome the error.

Can we throw an error in java ,if yes plz give an example?
Hi,
How can we throw an error in java like an exception(using try catch).If an error can be thrown then what is the diffrence between error and exception because both can be thrown using throwble.
Thanks
SumitError and Exception both are subclasses of Throwable class, so both can be thrown(I don't want to explain by an example). Now Error class defines exceptions that are not expected to be caught under normal circumstances. Exceptions of type Error are used by Java run-time system to indicate errors having to do with the run-time environment, itself.
"Stack Overflow" is an example of Error.
Errors are generally caused in response to catastrophic failures which can't be handeled by your program. -
I need to throw errors from Java and to receive them in Flex.
My idea is using xml with error id and message, and maybe the Flex
component which should show the error.
Is there any other way to do it? Another interaction between
Java and Flex?
Thanks in advance
Tuli-OXML wrapping error info written to response when java code
throws and having a common component on the flex to handle this
situation -- maybe on the fault event. -
Application using Http Post... getting error response

This issue is only happening in my country (Ecuador). I have some friends in Argentina and they have no problems at all. What are the posible causes for this problem?
Message Edited by andufo on 07-09-2009 08:43 PMHi again,
im attaching all the info you request:
What does the program actually do?
Social network (because of the TOS of this forum im not allowed to post project names or urls)
What is it trying to send when you submit a request?
What url is it posting the information to?
Im attaching all this at the end of the post.
Is it the 'exact' same application that works in other countries?
Yeap, the exact same one...
Is it supposed to be useing the Internet Browser?
No, it is a native app. The Browser is not used at all.
Are you on a BlackBerry Enterprise Server?
Im on BIS, all the users use BIS.
Technical details:
1) The app makes an Http Connection (POST) to:
http://mydomain.com/api/call?param1=abc¶m2=xyz
2) This is the Http connection configuration:
httpConnection = (HttpConnection) Connector.open(url);
HttpConnection.POST;
("Content-Type", "text/plain; charset=utf-8");
("Host", 'mydomain.com');

To find the error in java code if any
i was learnig java.net package and this is the code i wrote to read the contents directly from a given url using openStream() method of URL class and got the message 'error' from
java.io.IOException which i had given in the catch block. please tell me what is happening & how
could i read the content from an url with url class method.
import java.io.*;
import java.net.*;
public class url
public static void main(String[] args)
throws java.io.IOException,java.java.MalformedURLException
try{
URL yahoo = new URL("http://www.yahoo.com");
BufferedReader read_io = new BufferedReader(new InputStreamReader(yahoo.openStream()));
String line;
while((line =read_io.readLine())!= null)
System.out.println(line);
line.close();}
catch(MalformedURLException e)
System.out.println("error");
catch(IOException e)

Are you sure String has a close method? I'm not sure your code compiles.
Exceptions have a getMessage method, which can be useful (and a printStackTrace method that can be even more useful.) -
