I am a Java developer. I do not have much experience on web app front end development, but now need to prepare for a job interview which mostly requires JSP, HTML, css and Javastript. I know EL and JSTL is important, but do I need to prepare about custom tag developemt, since my time is limited?
I understand java.util.Vector is thread-safe in J2SE. How about in Vector and Hashtable in J2ME? I did not find any documentation about this. Thanks in advance. [ February 23, 2007: Message edited by: Nigel Chou ]
1. It is not errata. Pls check with p678 "IMPORTANT: The Container's rules for ordering filter". Mapping <url-pattern> goes first, then <servlet-name>. 2. It is not errata. It says Which ... pattern, not patterns. 3. It says Which design pattern is.., so it has a single option. Furthermore, can Transfer Object improve client performance through caching?
It seems that DD only provides mechanism for Listeners to work for the whole application, instead of some specified Servlet. Am I right? If it is true. I feel it is a flaw, since sometimes you may want you ServletRequestListener to work not on every request to all the Servlets in the application. It is inefficient.
