Though i am well versed with JSP standard tags, I want to learn more about taglibs, JSTL. What are the best books/resources available for getting more familiar and expertise in that area ? Any help greatly appreciated.

Hi Everybody,
I need answers for these questions immediately.
1.What in your opinion are the three most crucial risks of developing on a J2EE application server that is the not the same as in production? Feel free to use specific examples of technologies, and different issues as they may arise in the Software Development Lifecycle. The issues that we are looking for may differ depending on what stage of the lifecycle the project is in. Cite specific examples (if any) from your experience, related to JBoss, BEA WebLogic, IBM Websphere Application Server.
2.What are the most commonly used design patterns used in a custom development application? Specifically, speak to applications that may have interfaces to different applications. Considerations would be a clean design such that other interfaces could be added with minimum code changes to the core modules? State specific design patterns that you have used to handle such situations.
3.Why would one use a singleton pattern instead of a class with static methods to ensure efficient memory usage?
4.What are the most common strategies used in Java to do transaction management where EJB�s are not being leveraged? For e.g. what kind of multi-threading issues would one have to take care off in the data access layer of an application where there is a possibility of a user creating or modifying the same entry simultaneously? Cite specific examples from experience if necessary.
5.Cite specific project experiences you have built XML DTDs and Schemas to map data in database schemas into XML format? Cite specific project experiences where you developed scripts to load Data in and out of databases? What file formats have you used in such experiences? What considerations apply when going about designing a custom application / module which does intensive data processing?
-- would be really appreciated.

I was trying to build a js function dynamically from another function and trying to call it. But, somehow the dynamic function doesnt work. Can any one help me why the alert('hello') in the function: loadData_313937043() is not being called ?
------------------------------------------------------------------------
function testMe() {
var testUid= '313937043';
var ld = 'loadData_';
var ch = ld.concat(testUid).concat('()');
alert(ch);
ch;
}

function loadData_313937043() {
alert('hello');
}
------------------------------------------------------------------------

I have a large chunk of string in my xml and it has to be splitted and processed in my xsl.
Does any one know how to tokenize a string in xsl ?
Is it more like a calling class needs to know what exceptions the super class methods throw or for any other purpose do we need to add the
"throws" clause ?
Why is necessary to explicitly state in throws clause of a method the types of exceptions that that method may throw but for which their is not a catch handler? Since Java is statically scoped can not the compiler on its own determine if there is a catch handler for a given exception in an enclosing scope by examining which throw statements are present in the method bodies?
Where can I find K&B mock test ??
Hi,
Try to compile it and check,67 is the right answer, dont worry, sometimes u find wrong answers too

hi,
Applets are web-applications, say the client side java which is more interactive than ordinary HTML interfaces.
Servlet is an extension of a webserver, so called. They perform request-response duties and run in the servlet container within the multithreaded server.
JavaServerPages is such technology which integrates java with content and inturn converted back to a servlet.
