[java ee programming] Lab-4016 BookDAO source file is different than in lecture file
I'm trying to get a little head start on the upcoming class and I
noticed that in Lab-4016 you show:'
public BookDBAO() throws Exception {
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/
env);
DataSource ds = (DataSource) envCtx.lookup(jdbc/BookDB);
con = ds.getConnection();
... but the actual file has most of that code commented out and
replaced with ...
public BookDBAO() throws Exception {
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/
env);
/*System.out.println(initCtx is + (initCtx==null ?
null. : created.));
System.out.println(envCtx is + (envCtx==null ?
null. : created));
DataSource ds = (DataSource) envCtx.lookup(jdbc/BookDB);
System.out.println(ds is + (ds==null ? null. :
created.));
con = ds.getConnection();
System.out.println(con is + con ==null ? null. :
created.);
*/
Class.forName(dbdriver);
con = DriverManager.getConnection(url, username,
password);
When I remove the comments and instead comment out the last 2 lines, I
get the message:
messageServlet BookStoreServlet is not available
Not sure what's going on here. Any clues?
Thx, Dennis

Rajesh, Please remember that this is a voluntary class, as such, refrain from flagging any message as Urgent. If you think its too urgent for you and can't wait till Sang updates anything in his own time, I would suggest you 'Urgently' enrol in a local college. That way, you won't have to wait for anything to be updated here. -Evans http://www.javawug.org Date: Sat, 24 Jan 2009 03:12:13 +0530 From: raj31_saw...@yahoo.com Subject: [java ee programming] Important and Urgent!!!

[java ee programming] Re: Need help on J2EE Application
Hello Guys, What ever ankit telling is correct, But i want to know, (To Ankit) why you are suggesting comma separated values in field?? Isn't it appropriate to use another table which has Page Name (or Page Id) and corrspondign user id? So it will be very simple to handle and most importantly easy to modify To Dipesh, If your pages are dynamic, i mean you are changing contents of it using some forms (like Forum and forum notification) then it is easy to do. But if you are replacing static pages (or dynamic pages) and still you want to notify user, then i think you should replace your page using specialized (self developed) servlet form (you have to make one form for uploading your static file or dynamic files). Or you can make a service which checks you page's last modified date on regular intervals and based on that you send emails to all the users. Please don't hesitate to ask if you have some confusion Regards, Nachiket On Thu, Jan 22, 2009 at 4:00 PM, Ankit Garg ankit.niit...@gmail.com wrote: Well I don't think this should be a big problem. You just need to keep track of all the people who have subscribed for a page. And you have to do the opposite too i.e. the user must be able to track all the pages he has subscribed for. I think you will implement a database for keeping the information of a page. In that you just need to add a column containing comma separated list of IDs of users who have subscribed for the page. Then when any updates are made to the page, then you just need to split the comma separated list and find the email ids of the corresponding users. I don't what kind of content you are going to have on the pages so can't tell what kind of notification will be sent to the user. To do the opposite i.e. to find all the pages that a user has subscribed for, you need to run a query on the comma separated column of the article table where you would match the value of the column like this - columnName like %userId% . This will find all the pages for which the user has subscribed. Just tell me if you need further help :) ...

[java ee programming] Re:
Hi,
Every time when you see must be caught or declared to be thrown you have
two choices:
Catch the exception on throw it back to the calling function.
Look here
http://java.sun.com/j2se/1.4.2/docs/api/java/io/FileInputStream.html#FileInputStream(java.lang.String)
The text:
throws FileNotFoundException
http://java.sun.com/j2se/1.4.2/docs/api/java/io/FileNotFoundException.html
in FileInputStream constructor is also from the constructor
signature and specifies that this constructor will not be finished
(ant not returning a object)
if the file cannot be found.
First method : CATCHING THE EXCEPTION
try{
FileInputStream f1 = new FileInputStream(myProp2.txt);
..
}catch(FileNotFoundException ex){
System.out.println(File not founded);
System.exit(1);
}
The second method. THROWING THE EXCEPTION
Example: we don't want to catch inside the function testMe, so the
exception will be thrown from
testMe to the calling function, here the main function
public static void main(String[] args) {
try{
testMe(myProp2.txt);
}catch(FileNotFoundException ex){
System.out.println(File not found);
System.exit(1);
}
}
/**
* not catching the exception, so it throws it back to the calling function
*/
private static void testMe(String str) throws FileNotFoundException{
FileInputStream f1 = new FileInputStream(str);
}
There is a yellow bulb with an exclamation point just in the line you have
the FileInputStream constructor. If you go there with the mouse you will see
the error before you compile.
Because this is a simple project, you will catch the exception inside the
main function.
And, as a rule, anytime you use a method or constructor, see if throws
exceptions. Anyway the
IDE will warn you before you compile the file.
Note also that this is a very simple error and you maybe want to enroll to
Java with Passion first!
Happy coding!
