Oops. Read the fine print for SimpleDateFormat: "Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally." Rather than introducing another bottleneck by synchronizing, you may be better off keeping separate SDF objects for each request. If this is your only webapp, you could get away with storing one per thread as a ThreadLocal. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
