Hi,
I am not sure, but I thiunk you need to rewind the input ByteBuffer
to position 0 before you can decode after the put.
Best regards,

Hi All,
I've been working with SNMP4J for a couple of weeks adding it to a project that
I am working on.
I am using SNMP4J for OID -> BER and vice-versa.
In the below example, I am trying to from BER -> OID, but I am getting an error.
I am not seeing where I am going wrong??? It is expecting more, but I am using
a direct conversion from oOID.encodeBER(), so I am not sure what more it is
expecting?
Help Please!!!
CODE:
String sSnmpOID = "1.3.6.1.2.1.4115.10.1.14.0";
System.out.println("PRE-OID-DOT-NOTATION: " + sSnmpOID);
OID oOID = new OID(sSnmpOID);
ByteArrayOutputStream baosBER = new ByteArrayOutputStream();
try {
oOID.encodeBER(baosBER);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//This only displays what is contained in ByteArrayOutputStream
System.out.println("baosBER: " + new
HexString(baosBER.toByteArray()).toString());
//Convert to ByteBuffer
ByteBuffer bbBER = ByteBuffer.allocate(baosBER.size());
//Add byte Array
bbBER.put(baosBER.toByteArray());
//Create BERInputStream from ByteBuffer BER
BERInputStream bisOID = new BERInputStream(bbBER);
//Create OID Object
OID oOIDNew = new OID();
try {
oOIDNew.decodeBER(bisOID);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("PST-OID-DOT-NOTATION: " +
oOIDNew.toDottedString());
OUTPUT:
PRE-OID-DOT-NOTATION: 1.3.6.1.2.1.4115.10.1.14.0
baosBER: 06 0B 2B 06 01 02 01 A0 13 0A 01 0E 00
