Thread: java.io.IOException: Premature EOF

Hi guys!

I am getting a java.io.IOException: Premature EOF error about some urls (usually, the ones with a huge content), after executing the following peace of code. Any ideas?

public static void urlReader(String url, String path, String fileName) {
        String inputLine = null;
 
        URL x = null;
        BufferedReader in = null;
 
        createFile(path, fileName);
 
        try {
            // Create file
            FileWriter fwstream = new FileWriter(path + fileName);
            BufferedWriter out = new BufferedWriter(fwstream);
 
            x = new URL(url);
            in = new BufferedReader(new InputStreamReader(x.openStream()));
 
            while ((inputLine = in.readLine()) != null) {
 
                if (inputLine.length() > 0) {
                    //System.out.println(inputLine + "\n");
                    out.write(inputLine + "\n");
                }
            }
 
            // Close the input stream
            in.close();
 
            // Close the output stream
            out.close();
        } catch (IOException ex) {
            System.out.println(ex);
            System.out.println("Application aborted while function \"urlReader();\" was executing!");
            System.out.println("url = \"" + url + "\"\n");
            System.out.println("inputLine = \"" + inputLine + "\"\n");
            //System.exit(-1);
        }
    }

NOTE: I tried to modify the above code using the following one (and different values of BUFFER_SIZE variable) but unfortunately, the same error still occurs. Please, take a look and tell me if there is any wrong with it!

static int BUFFER_SIZE=1024;
byte[] buffer = new byte[BUFFER_SIZE]; // or some other size, 
int charsRead = 0;
while ( (charsRead  = in.read(buffer,0,BUFFER_SIZE) != -1) {
  out.write(buffer,0, charsRead);
}

Kind regards,
CrazyVag.

Hi! and thanks for your response. Do you mean something like the following? Unfortunately, this doesn't work. Actually, application stops working after reading the first file or something like that... Is there any misunderstood? Sorry about my quwestions but I am newbie in Java.


public static void urlReader(String url, String path, String fileName) {
String inputLine = null;

URL x = null;
BufferedReader in = null;

createFile(path, fileName);

try {
// Create file
FileWriter fwstream = new FileWriter(path + fileName);
BufferedWriter out = new BufferedWriter(fwstream);

x = new URL(url);
in = new BufferedReader(new InputStreamReader(x.openStream()));

while ((inputLine = in.readLine()) != null) {

if (inputLine.length() > 0) {
//System.out.println(inputLine + "\n");
out.write(inputLine + "\n");
}

while (!in.ready())
{
try {
Thread.sleep(100); // wait for stream to be ready.
} catch (InterruptedException ex) {
Logger.getLogger(application.class.getName()).log( Level.SEVERE, null, ex);
}
}
}

// Close the input stream
in.close();

// Close the output stream
out.close();
} catch (IOException ex) {
System.out.println(ex);
System.out.println("Application aborted while function \"urlReader();\" was executing!");
System.out.println("url = \"" + url + "\"\n");
System.out.println("inputLine = \"" + inputLine + "\"\n");
//System.exit(-1);
}

Any suggestion?

Okay. Here we are!

I added the following command (i.e. ex.printStackTrace() inside the catch block in order to show you the stack trace.
I really concern about the behavior of my application because the "stuck" comes from different urls in each execution...
Also, it is worth to notice that, after the installation of netBeans and the app-execution in a new machine, the app completed successfully!
But, this doesn't happen again! What the !@#$ is going on? How can I solve the bug?
Some guys told me about the following improvement but neither this worked out!

while (!in.ready())
{
Thread.sleap(100); // wait for stream to be ready.
}

run:
Application aborted while function "urlReader();" was executing!

Thanks helloworld922, but...
Ohhhh my GOD!
What can I do...
It starts getting on my nerves....

As a newbie, I am not familiar with the stack trace.
Is there any way of using this kind information?

Hi!

I see it's a really old post, but now I have the same problem, really annoying. It works on an other machine, but on my mashine I get the same Exception.. I'M using Jax-ws rt and only occurs the problem when using mtom..

I think we have the same problem
