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

[dug201]

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:

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

My 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?

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.

[Tolls]

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:

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.

[dug201]

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.

[Tolls]

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.

[dug201]

Thanks Tolls.

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

[Tolls]

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.

[dug201]

ha lol, thanks.
