Methods Summary
protected com.sun.corba.se.impl.encoding.CodeSetConversion$CTBConvertercreateCharCTBConverter()
Override the default CDR factory behavior to get the negotiated code sets from the connection. These are only called once per message, the first time needed. In the local case, there is no Connection, so use the local code sets.

        CodeSetComponentInfo.CodeSetContext codesets = getCodeSets();

        // If the connection doesn't have its negotiated
        // code sets by now, fall back on the defaults defined
        // in CDRInputStream.
