From source file:org.apache.directory.server.ldap.handlers.extended.StoredProcedureExtendedOperationHandler.java

    String procedure = req.getProcedureSpecification();
    Entry spUnit = manager.findStoredProcUnit(session.getCoreSession(), procedure);
    StoredProcEngine engine = manager.getStoredProcEngineInstance(spUnit);

    List<Object> valueList = new ArrayList<>(req.size());

    for (int ii = 0; ii < req.size(); ii++) {
        byte[] serializedValue = (byte[]) req.getParameterValue(ii);
        Object value = SerializationUtils.deserialize(serializedValue);

        if (value.getClass().equals(LdapContextParameter.class)) {
            String paramCtx = ((LdapContextParameter) value).getValue();

        }//from  ww w  . ja v  a 2s  .  co m

        valueList.add(value);
    }

    Object[] values = valueList.toArray(EMPTY_CLASS_ARRAY);
    Object response = engine.invokeProcedure(session.getCoreSession(), procedure, values);
    byte[] serializedResponse = SerializationUtils.serialize((Serializable) response);
