web service calling problem? - web-services

Question

When I call a web service data does not come in the proper way. Some blocks are there string, integer, chars are there means mixed data in json form.
1) When I use this approch to convert the data...
StringBuffer sb = new StringBuffer();
byte[] buf = new byte[256];
int n = 0;
while ((n = StrReader.read(buf)) > 0)
{
sb.append(new String(buf,0,n));
}
String returnContent = sb.toString();
System.out.println(new String(returnContent));
StrReader.close();
}
output...
text/htmlj
~"115.252.128.200", "roles": { "1": "anonymous user" }, "session": "", "cache": 0 } } }
No stack trace
2) and when I use this approch to convert the data...
dis = new DataInputStream(hc.openInputStream());
byte[] data1 = new byte[20];
int len = 0;
StringBuffer strBuffer = new StringBuffer();
while ( -1 != (len = dis.read(data1)) )
{
received = new String(data1, 0, len);
System.out.println(received);
}
OUTPUT....
text/html
j
~Salse, "#data": { "se
ssid": "fef51cf48aca
46e3b3aedafc02860f25
", "user": { "uid":
0, "hostname": "115.
252.128.200", "roles
": { "1": "anonymous
user" }, "session":
"", "cache": 0 } }
}
Outer---->>>}
No stack trace
NOTE.... the 'received' variable loses our data when it come out of loop...

Answer 1

The question appears to be: why does the local variable 'received' have only a fragment of the text that is printed to the console. It is because the variable is assigned a new string for each batch of bytes that are read from the DataInputStream.
This code does not appear to concisely get the job done - why use a DataInputStream for example - so perhaps asking about the larger task at hand will be more useful.
