canot find sybol : method write(byte[]) - urgent help

Hello Guys;

I have a simple Java code tha post xml to another url.

I'm getting an error I'm not sure how to resolve.

the error states:

Code:

---

cannot ind symbol
symbol : method write(byte[])
location: calss java.io.OutputStreamWriter
out.write(request.getBytes(sendEncoding));
  ^

---

My Code:

Code:

---


static int port = 80;
static String hostname = "xx.xx.xx.xx";
static List<String> IDs = new ArrayList<String>(); //id for the download
static List<String> statuses = new ArrayList<String>(); //http status for the download request 200,201,204,400
static List<String> filenames=new ArrayList<String>();
static List<String> sites=new ArrayList<String>();
static String outputFolder = "/xxx/input_data/xxx/";
boolean downloadFailed = false; //if a download fails in the download() function, wait 5 mins then retry


public String push2(String XML_IN) {

String response = "";

String request = XML_IN;

String sendEncoding = "UTF8";

HttpURLConnection urlConn = null;
 
OutputStreamWriter out = null;

InputStream in = null;

try {

 
URL url = new URL("http://url");

urlConn = (HttpURLConnection)url.openConnection();

urlConn.setRequestMethod("POST");

urlConn.setDoOutput(true);

urlConn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");

urlConn.setRequestProperty("Accept","application/xml");

urlConn.setRequestProperty("charset","UTF-8");


urlConn.connect();

System.out.println("CATCH-->Entering push mode");

out = new OutputStreamWriter(urlConn.getOutputStream());

out.write(request.getBytes(sendEncoding));

out.flush();

out.close();

int status = urlConn.getResponseCode();

System.out.println("Status code:" + status);

//if http code 200 is not returned, there's an error.
if (status!=200) {
 in = urlConn.getErrorStream();
}
else {
in = urlConn.getInputStream();
}


    InputStreamReader inReader = new InputStreamReader(in, sendEncoding);
   
    StringBuffer responseBuffer = new StringBuffer();
   
    char[] buffer = new char[1024];

    int bytes;

    while ((bytes = inReader.read(buffer)) != -1) {

        responseBuffer.append(buffer, 0, bytes);

    }

    response = responseBuffer.toString();

    System.out.println(response);

if (status!=200) {   
    failSession("HTTP status code wasn't 200, so must be something wrong - FAILED");
    }
}

catch (Exception e) {
e.printStackTrace();
}

finally {
if (out != null) {
try {out.close();} catch (Exception e) {}
}

if (in != null) {
try {in.close();} catch (Exception e) {e.printStackTrace();}
}

if (urlConn != null) {
urlConn.disconnect();
}
}

return response;
}

Have you looked at the API for OutputStreamWriter? If not, why not?

I have looked at it, still lead me to no solution. I'm a php programmer and have not touched Java for many years, so would appreciate any specific pointers or code example.

Here's the API then.
As you can see there is no write method that takes byte[].
And that's no great surprise since a Writer write characters, not bytes.

thanks.

I've changed this bit:
out.write(request.getBytes(sendEncoding));

to just:
out.write(request);

while this works, I also needed to apply some url_encoding to the xml string being sent, and while it complies sucessfuly, when running it I get: FATAL ERROR : Caught a fatal signal or exception

this is how I'm url encoding it:

Code:

---

URL url = new URL("http://xxxxxx/");

urlConn = (HttpURLConnection)url.openConnection();

urlConn.setRequestMethod("POST");

urlConn.setDoOutput(true);

urlConn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");

urlConn.setRequestProperty("Accept","application/xml");

urlConn.setRequestProperty("charset","UTF-8");

//urlConn.setRequestProperty("Content-Type","application/xml;charset=" + sendEncoding);

urlConn.connect();

System.out.println("CATCH-->Entering push mode");

out = new OutputStreamWriter(urlConn.getOutputStream());

//out.write(request.getBytes(sendEncoding));URLEncoder.encode(request,"UTF-8")

String urlEncode = URLEncoder.encode(request,"UTF-8");

out.write(urlEncode);

System.out.println("CATCH-->XML Request:" + urlEncode);

out.flush();
 
out.close();

What's the full error plus stack trace.
If it's a JVM crash then that's something we really wouldn't be able to handle here.

thats the only error available to me.

my issue is that, the code works fine until I url_encode it. we'll it kind of works, it successfuly posts the xml, but I'm getting a status code 500 back and I think I need to url encode me xml request and that's what the stickig point is. Any insight or other way of doing would be much appriciated.

I'd look at the other end and see what the error is.
Assuming you have access to wherever it is you are sending this stuff.

Thanks Tolls.

From your opinon am I setting all the correct urlConn.setRequestProperty headers in my code above?

No idea.
I only ever look at these things when I'm actually doing them.
I rarely bother remembering the ins and outs...and then I test it and tweak as needed.

ha lol, thanks.
