Hi we having the following code and we are using JRUN3.x Now we are migrating the code to JRUN but JRUN 4 don.t have the allaire.ejipt.TimeoutException class and This is runtime exception.
How to resove the issue

 try
        {
            LOG.debug("Request legacy connection");

            long startTime = System.currentTimeMillis();
            connection = legacySource.getConnection();

            long endTime = System.currentTimeMillis();
            LOG.warn("sem time = " + (endTime - startTime) + " ms");
            LOG.debug("Allocate legacy connection");
            monitorConnections(connection, true);
        }
        catch (allaire.ejipt.TimeoutException e)
        {
            String msg = activeConnections();
            throw new HbsGenericRuntimeException(e, true, msg);
        }
