[SNMP4J] Going from BER Input Stream to OID String

[Garcia, Maurice]

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());
