Display Message using Servlet

I tried to display message prompt to the user using servlet. Can anyone has this code or guideline that can guide me??

what you need to do is
request.setAttribute("error", "search item doesnot exist") if surname, designation is null or invalid and forward request to results.jsp page.
In results.jsp page, check this attribute "error".. if its null then display results present in "arraylist" attribute else display "error" attribute value.
When you are catching exception, in catch block redirect to error.jsp.

How to display message using default lock in ORACLE 9i?

I am using ORACLE 9i I am inserting a same record in a same table (which is having primary key) of same user with different sql editor (or from different machines).
with same time.
One person is able to insert the record..
But other one is in processing state, once the inserted person give commit,then only other person got the message "Primary key constraint voilated".
This is bcoz of concurrency in oracle. For this purpose Oracle uses default lock.
Is it possible to give message to other person like "One user is using this table..", after a record is inserted and before commit is get issued by the inserted user?
how can i do this?
Thanks a lot for your help

Tomcat web.xml "display-name" using flex.messaging.MessageBrokerServlet

 Hello,
When my web application starts with the BlazeDS servlet flex.messaging.MessageBrokerServlet defined in the web.xml we have an error because in the display-name defined at top level in web.xml we have some text containing character ':'. The error is traced to inside the function
 flex.management.BaseControl.getObjectName()
Which gets the object name, and this function calls
 BaseControl.getApplicationId()
which finally calls
ServletConfig.getServletContext().getServletContextName()
This will return or display-name from the web.xml with all it's text. This text contains among other characters the character ':'. We use this tag for the display in the Tomcat Manager to see version number and other of deployed project.
After retrieving this name it is appended in the getObjectName() function to a buffer, this StringBuffer that already contains flex.runtime. and now this name is appended (still with all that we are using for Tomcat Manager with ':' character and other). After the name, other things are appended. Our problem is that, after constructing this StringBuffer an instance of javax.management.ObjectName is created. In it's constructor it takes a String name as input. This String is parsed in base of characters ':', '*', '?', '\n' and so on, and since we have some of these characters in our display-name it all goes wrong.
 My question is, if this is a bug, a limitation or if it is documented that using flex.messaging.MessageBrokerServlet we can not use certain characters in the display-name of the web.xml?
 Greetings, Tim

I keep getting a display message saying this cable or accessory is not capitiable with this apple product may not be reliable with this iphone even when i have no cable or accessory in use

My iphone 5 has been saying this for days now. Yes I have recently purchased a motorola ear piece for easy talking while walking, but i have also used a 10ft cord purchased at walmart for months now and no display before the motorola. now even without anything plugged in ,I still get the display message on my phone saying" the cord or accessory is not capitable with this iphone and may not be reliable with this iphone.
what DO I do ?! is there something I can do without going to either Sprint or Apple for help.... will this be damaging to my iphone ?! HELP before its too late.
sincerely,
Apple lover JAJA

Try resetting your iPhone. Hold the on/off and home buttons together for about 10 seconds till the Apple logo appears.
CAUTION - This may get rid of the warning for now, but the issue the warning points out still remains. One or both of your cables is certainly suspect.

TS1456 My 4th Gen iPod Nano isn't displaying a "Use iTunes to restore" message, but iTunes is displaying a restore message when I connect it. I have original music that I can't back up on my iPod. Is there any way that I can fix the iPod without restoring

My 4th Gen iPod Nano isn't displaying a "Use iTunes to restore" message, but iTunes is displaying a restore message when I connect it. I have original music that I can't back up on my iPod. Is there any way that I can fix the iPod without restoring it?

It's not designed to work like this. When you sync, the iPod stores some information that basically says 'this iPod belongs to computer xyz'. Apple did this to prevent copyright issues (syncing someone else's music).
If you really want to do this, you'll have to at least tie both iTunes installations to the same account. Maybe have them sync with each other.

Displaying results from a database query using servlets

I have this HTML form where users can search a MS Access database by entering a combination of EmployeeID, First name or last name. This form invokes a Java Servlet which searches the database and displays the results as an HTML page. I am giving the user the choice of displaying 3, 5 or 10 results per page. I want to know how to do that using servlets. If a particular search results in 20 results, the results should be displayed in sets of 3, 5 or 10 depending on the user's choice. If the user makes a choice of 5 results per page then 4 pages should be displayed with a "next" and "previous" button on each page. I want to know how this can be done.

Arun,
I'm not sure how to do this using JSP as I have not worked on JSP.
But I can give you a hint on how to do this within normal java class as I've used this in my current project.
In your core class/bean that generates the entire resultset, you need to run a loop that will scan through the desired number of records in the resultset.
To do this, you have to have skip and max parameter in your URL.
Somthing like http://server.com/myservlet?skip=0&max=10 to display first 10 records, http://server.com/myservlet?skip=10&max=10 to display next 10 records. The <next>parameter would be fed in by the user by a simple form in your web-page. If you need to hold this <max-num-of-recs-per-page> param, you can store it in a cookie (since this is nothing crucial piece of info, don't need to use session obj etc...cookie will do) and get the value each time you display the resultset.
So, essentially, suppose you are at the first page and you wish to show 10 recs at a time. The link for "Next" button would be http://server.com/myservlet?skip=10&max=10
when at the second page, you'll have
"priv" button as http://server.com/myservlet?skip=0&max=10 and
"next" button as http://server.com/myservlet?skip=20&max=10 and so on...
hope this makes sense..

To display a continuos Error Message using BADI

Hi Everybody,
 There's a transaction that makes use of classes and interfaces to display an ALV grid with input enabled frames and fields. There's a need to display an error message using a specified BADI method, which gets triggered after the user enters the input. The error message is working fine for the first time.But when i'm trying to enter the same input and press enter after the error message, the transaction is getting closed. How can i display the same error message, until and unless the user enters the correct input ? I've tried to trace the control using the debugger after the enter is pressed, but the debugger is also getting closed and the control is coming out of the transaction. Help me out in displaying the error message.

Hi,
Open the interface and go to the Methods tab.
Select the Method and click on Parameters.
In the method parameters, declare a variable
RETURN Changing Type ALM_ME_BAPIRET2_T.
Now, inside your code, declare DATA : ls_return TYPE bapiret2.
and populate this RETURN table, something like:
 if not ( wa_mara-mtart eq 'SPAR' or wa_mara-mtart eq 'ZMRO' ).
 CLEAR ls_return.
 MOVE 'E' TO ls_return-type.
 MOVE 'ERR_MESSAGE' TO ls_return-id.
 MOVE '999' TO ls_return-number.
 MOVE 'Enter proper error message here' TO ls_return-message.
 INSERT ls_return INTO TABLE return.
 endif.
Then, back in your program, check if this table is empty proceed otherwise, STOP or EXIT.

Subramanian

Displaying japanese chars using servlet (posted in Java programming too)

I am trying to display the japanese characters inputed by the user using
html form and I am using servlet...
After reading the input and when i try to display i get ????
how can i solve this.
It was originally posted in Java Programming forum. but i think the question suits here....heres the link for original post
http://forum.java.sun.com/thread.jspa?threadID=670419&tstart=0
sorry for posts at two different forums

After reading the input and when i try to displayDisplay on what?
Usually, if request.getCharacterEncoding() doesn't return viable result, then you should call
request.setCharacterEncoding() with a proper value. If user send Shift_JIS string as form
input, then the argument value should be also "Shift_JIS". When in doubt, use "UTF-8".
Then, you call response.setContentType("text/html; charset="Shift_JIS"), etc.
