For example , I try to translate "1.3.6.1.2.1.1.1.0" to "sysDescr.0".

    public MibValueSymbol findSymbolByOid(String oid) {
         MibValueSymbol  sym;
         int             pos;
         int             value;

         sym = this.getSymbolByValue(oid);
         if (sym == null) {
             pos = oid.lastIndexOf(".");
             if (pos > 0) {
                 sym = findSymbolByOid(oid.substring(0, pos));
             }
            //here we have get a Symbol sysDescr,
             if (sym != null) {
                 value = Integer.parseInt(oid.substring(pos + 1));
                 sym = findSymbolChild(sym, value);
             }
            //here , if don't modify findSymbolChild , sym == null now .
         }
         return sym;
    }

    public MibValueSymbol findSymbolChild(MibValueSymbol sym, int value) {
        ObjectIdentifierValue  oid;

        if (!(sym.getValue() instanceof ObjectIdentifierValue)) {
            return null;
        }
        oid = (ObjectIdentifierValue) sym.getValue();
        for (int i = 0; i < oid.getChildCount(); i++) {
            if (oid.getChild(i).getValue() == value) {
                return oid.getChild(i).getSymbol();
            }
        }
        if (oid.getChildCount() == 1) {
            return oid.getChild(0).getSymbol();
        }
        // return null;   //here , if return null ,findSymbolByOid will return 
null
        else{
            return sym;
        }
