DoPost can't display the result page
After I deploy j2ee application.I excute servlet page.
it show the page that code from doGet,but when I click submit page it doesn't show anything.So,I guess it cause from doPost.
and I receive CONN-003 error from kas.
UTIL-013 NSAPICLI-009 NSAPICLI-012and PROT-001 from kxs.
and the kjs show catchException
How can I resolve this error?
Thanks
Sung
What are you doing in your doPost method?
What ever you are doing that is throwing an exception is probably the key to the problem.
The KAS process is a watchdog, so its unlike that its message is relevant. (Unless it is reporting that you have crashed your JVM.)

How can I display the same page when I'll press
i have a jsp page. It contains user name & password.
and a link like SIGNOUT COMPLETELY. when i press the back button it should show only this page.
You have noticed one thing that when u sign out from YHAOO MAIL then a page is displayed
USERNAME : [email protected]
PASSWORD :XXXXXXXXXX
SIGNOUT COMPLETELY
when this page is dispalyed and u press the back button of the browser
it displays the same page. How it happens?Kindly neglect the previous post.....
Okay check something like this
1).maintain either a HttpSessionListener or a session flag try to checkout whether the user is active or else close the PrintWriter.
2).Prevent caching of the webpage by using customary meta tag or by response,setHeader("Cache-Control","no-cache");
way...
Guess tht shud work..... -

}I also did a Servlet Paging but I later found a Paging example that used MVC architecture which I found to be more efficient.
This post has a good example in this link: http://forums.devshed.com/java-help-9/paging-in-jsp-85968.html?p=382695#post382695
After I downloaded the example I made alot of changes and got rid of the scriptlets in the JSP and brought it more up to date using JSTL.

Rangwhat is the datatype of mty_date?
it seems like you want to do a count(*) regardless of what month it is, so why all the case statements?
If mty_date is a DATE datatype then:
Substr(to_date(a.mty_date,'DD-MMM-YYYY'),4,3)is bad code.
If you want the month name from a date you would use something like...
SQL> select to_char(sysdate,'MON') from dual;
TO_

Passing a request to another page and displaying the new pages URL
I've got a number of pages on my site that communicate with a database. Everything is working well but I am now trying protect myself from Stupid User Errors.
Specifically when a user performs a database operation and then hits the refresh button repeatedly on the page that did the operation. (SQL Inserts are particularly ugly in this situation)
My problem is that both the data handling and the resulting page rely on information in the request object from the original form.
I've tried processing the information on one page and then sending a redirect but this loses the request object. I've also tried using the forward method but it only displays the result page, it doesn't actually send the user there so refreshes will still mess me up.
What I really want is to do all my SQL operations on one page and then send them to a results page that can be refreshed as many times as they like without corrupting my database.
Any ideas?
PeteThe thought occurs to me that if you call an INSERT operation on your database, the database itself will employ deadlocks to prevent someone else (such as a refreshed session) from inserting into the database until the first query is completed.
So one thing you could do is modify your class object to first do a one-tuple SELECT and compare it with your INSERT statement. If the line exists, then abort the INSERT. This is more compute-intensive, but it is about the only way you can guarantee that regardless of the session-tracking technique you use, the desired value will never be inserted twice.
You should double check with your local DBA though - some databases actually do ignore multiple inserts if all of the field values are the same as an existing record, and other databases are tweaked such that updating a record over and over incurs a very minor performance hit such that it's not worth guarding against such a situation.
The only time I would be worried is if you somehow record a timestamp of when the information was actually submitted. And that's fairly easy to fix with Javascript - once the fields are filled in, mark a hidden field. If the fields change subsequently, change the hidden field. If the fields don't change (i.e., person submits over and over), then you keep the original timestamp, the tuple is exactly the same and the database ignores the duplicate INSERT. -
Display the result of a query in descending order.
Hello Experts,
How can I display the result of a query in descending order?
Thanks much in anticipation.
Regards.Hi Kumar,
If you want to display char in descending order, in the query designer set the sorting setting as desceing for that particular characteristics, or if you want to see the KF in descending order, create a condition on that KF and set as TOP N and set N as 999999, that would display your KF in descending order.

How can I display the vendor associated with result of my running total sum
I have a report that lists vendors with their most vecent order dates. I need to set up a rotation so that the vendor with the latest order date is next to be selected. I used the running total summary to pick the latest date. How can I display the vendor associated with result of my running total summary?
If your "latest" order date means the "oldest" order date, why don't you try this:
Go to Report tab -> Record Sort Expert -> Choose your order date in ascending order
This will make your oldest order your first record shown.
You can then create a running total count for each record.
Lastly, in your section expert under conditional suppress X+2 formula, write this:
{#CountRecords}>1
The result will only show the oldest record in your report.
I hope that helps,

Strange scenario,Oracle can not display the data in mysql correctly
I use Heterogeneous Service+ODBC to achieve "oracle access mysql"(any other method?),and now i find Oracle can not display the data in mysql correctly:
-------mysql------------
mysql> create table tst(id int,name varchar(10));
Query OK, 0 rows affected (0.00 sec)
mysql> insert into tst values(1,'a');
Query OK, 1 row affected (0.00 sec)
mysql> select * from tst;
------------+
| id | name |
------------+
| 1 | a |
------------+
1 row in set (0.00 sec)
mysql> show create table tst\G
*************************** 1. row ***************************
Table: tst
Create Table: CREATE TABLE `tst` (
`id` int(11) DEFAULT NULL,
`name` varchar(10) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8
1 row in set (0.00 sec)
-------------oracle ------------------
SQL> select count(*) from "tst"@mysql;
COUNT(*)
49
SQL> select * from "tst"@mysql;
id
1
SQL> desc "tst"@mysql;
Name Null? Type
id NUMBER(10)You can make the following query on the result page:
"select * from the_table where movietitle = ? and cinema = ?"
then you set movietitle and cinema to those which the user selected. If the resultset contains more than 0 rows, that means the movie is available.
Below is the sample code, it assumes you have a connection to the database:
PreparedStatement stat = myConnection.prepareStatement("select * from the_table where movietitle = ? and cinema = ?");
stat.setString(1, usersMovieTitleSelection);
stat.setString(2, usersCinemaSelection);
ResultSet res = stat.executeQuery();
if (res.next()) {
out.print("The movie is available");
} else {
out.print("The movie is not available");
}Now just add that to your JSP page. Enjoy ! =) -
