RE: [Mibble-users] problem with MIbLoader.load

[Hall, Matthew]

Yeah I don't think this is going to work right. Let's examine the API:

=====
public MibValueSymbol getSymbolByOid(java.lang.String oid)

    Returns a value symbol from this MIB. The search is performed by using the 
strictly numerical OID value specified. Differing from the getSymbolByValue() 
methods, this method may return a symbol with only a partial OID match. If an 
exact match for the OID is present in the MIB, this method will always return 
the same result as getSymbolByValue(). Otherwise, the symbol with the longest 
matching OID will be returned, making it possible to identify a MIB symbol from 
an OID containing table row indices or similar.
====

It appears that getSymbolByOid is MIB-local. Therefore it's not going to work 
unless the symbol you look up is specifically present in IF-MIB. Let's try 
something a little different:

=====
MibLoader loader = new MibLoader();
loader.load(new File(fileSNMPv2SMI));
loader.load(new File(fileSNMPv2TC));
loader.load(new File(fileSNMPv2CONF));
loader.load(new File(fileIANAifTypeMIB));
loader.load(new File(fileSNMPv2MIB));
loader.load(new File(fileIFMIB));

for (Mib mib : loader.getAllMibs()) {
    MibValueSymbol mvs = mib.getSymbolByOid(oid);
    if (mvs != null) {
        System.out.println("symbol [" + symbol "] located in mib [" + mib + 
"]");
    }
}
=====

Let me know if it helps, I haven't done much complicated programming with 
Mibble yet so this might not be quite right. :-) It seems like there must be 
some fancier way to do the lookup that's not tied to one MIB at a time...
