Memory issues while fetching content

Question

HI all,
I am using SAP KM Apis. however i am facing some memory issues while using them.
I am using getContent() api on a resource. and then getInputStream on the Icontent object. I am using a ByteArrayOutputStream for writing the data. here is the code snippet:
byte[] buf= new byte[4096];
InputStream inputStream = content.getInputStream();
ByteArrayOutputStream os = new ByteArrayOutputStream(1024)
while ((count = inputStream.read(buf)) != -1)
    os.write(buf, 0, count);
byte[] arr=os.toByteArray();
THis code consuimes a lot of memory . we need to optimize this. we also tried removing BYteArrayOutputSteam and directly read the bytes in chunk :
int n; 
do 
     n = inputStream.read(buf, 0,(int)content.getContentLength()); 
while (n != -1); 
however this approach has not helped us.
please suggest an approach where memory consumption is less and the entire content is fed.
thanks

Hi
This code worked for me for reading from a KM res...
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
return sb.toString();
Regards
