How to store binary data in Java

Question

I need to show news in my web aplication.So I am retrieving news from a Feed Server in which the field GEN_UNICODE_MESSAGE_1 gives the news data.News consists of both English/Arabic data.So how will I store the binary content in JAVA and how can I display the news in JSP?
I tried storing the binary content in ByteArrayInputStream and appended it using StringBuilder.But I didnt get the desired output.Output is seen as ÇáÎáíÌíÉ ááÇÓÊËãÇÑÇáãÌãæÚÉÇáÔÑßÉÇáÇãÓÈÊãÈÑÓÈÊãÈÑÅÌãÇá.Please help me.
Here GEN_UNICODE_MESSAGE_1 is of type BINARY.
try{
BufferedInputStream in=new BufferedInputStream(new ByteArrayInputStream((byte[])msg.getField("GEN_UNICODE_MESSAGE_1").value.get(h)));
//ByteArrayInputStream in=new ByteArrayInputStream(((byte[])msg.getField("GEN_UNICODE_MESSAGE_1").value.get(h)));
StringBuilder builder = new StringBuilder();
byte[] buff=new byte[1024];
int len;
while ((len=in.read(buff))!=-1){
builder.append(new String(buff,0,len));
String incomingmsg=builder.toString();
}catch(IOException e){}

Answer 1

BufferedInputStream bis=new BufferedInputStream(new ByteArrayInputStream((byte[])msg.getField("GEN_UNICODE_MESSAGE_1").value().toString().getBytes()));
BufferedReader br = new BufferedReader(new InputStreamReader(bis));What on earth is all this?
1. What is the type of msg.getField("GEN_UNICODE_MESSAGE_1").value()?
2. Whatever that type is, you are then converting it to a String.
3. You are then converting that to bytes.
4. You are then casting that to byte[], which it already is,
5. You are then wrapping a ByteArrayInputStream around that.
6. ... and an InputStreamReader round that ...
7. ... and a BufferedReader around that ...
8. ... and reading lines
9. ... and appending them to a StringBuilder
10. ... and converting that to a String.
Which you already at at step 2.
String incoming = msg.getField("GEN_UNICODE_MESSAGE_1").value().toString();Not sure whether that's correct given the charset issues, but if not the problem starts at step 2. In any case steps 3-10 add precisely nothing.
This is all pointless. The key question is (1). Answer that first.
2. The type of String.getButy

StringBuilder sb = new StringBuilder();
String line = null;
while ((line = br.readLine()) != null) {
sb.append(line + "\n");
br.close();
String incomingmsg=sb.toString();
