java.lang.RuntimeException: IOException reading reader null
Hi,
I am recieving:
java.lang.RuntimeException: IOException reading reader null
at com.sun.cldc.i18n.Helper.byteToCharArray(+169)
at java.lang.String.<init>(+9)
at java.lang.String.<init>(+9)
at ApplicationLayer.Actions.Accessories.CommunicateUtil.communicate(+228)
when I am calling: new String(receivedData,"UTF16");
recievedData is byte[] that contains UNICODE bytes (two bytes for each character).
What is wrong?

Here's the list of charsets supported by Java (1.4):
http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html
You'll notice it doesn't contain "UTF16" in the list. It does contain "UTF-16" though. Although I'm surprised you don't get an UnsupportedEncodingException instead of what you did get.
Moreover, sometimes it did work and after 2 or 3 uses of this line the exception accures.
I tried as you said UTF-16 but I got the same error.
I wrote this function in order to bypass the error:
private static String toUTF16(byte[] bytes) {
char chars[]=new char[bytes.length/2];
int index=0;
for (int i=0;i<bytes.length;i=i+2) {
short high=(short)(0xFF & bytes[i]);
short low=(short)(0xFF & bytes[i+1]);
short left=(short)(high<<8);
short k=(short)(left | low);
char value=(char)k;
chars[index]=value;
index++;
}
return new String(chars);
}
What do you think?
and what do you think was the error?
Thanks, Naor.>
