I am trying to figure out a bunch of code in jsp, it is a html form with some textfield and two button, one is "ok" and another is "cancel", I want to make different response when client click on the buttons, if they choose ok, I want to insert the value of those text field into an arrylist, and return back to previous jsp page, if they choose cancel, I just want to return back to previous jsp page, and with nothing changed in the arrylist, I was wondering how can I deal with the button name with both method "submit" and action"./some.jsp".
Please help! thx a lot!Make sure you name your submit button. Something like:
<input type="submit" value="OK" name="foo">
<input type="submit" value="CANCEL" name="foo">
Then, when you submit the page (let's assume you're submitting the page to itself), add something like this at the very top of your code:
<%
String x = request.getParameter("foo");
if (x != null) {
if (x.equals("OK")) {
// add OK handling code here
} else if (x.equals("CANCEL")){
// add CANCEL handling code here

Anybody who can help me? I really need your help
I've tried to execute J2ee tutorial examples.
I don't know why this sample didn't execute...I've already finished to set up J2EE and enviornment variables.
I was trying this part from j2ee tutorial titled as "Packing Web modules".
Whenever I type "asant create-war" to make web modules in command window. I always got error.
Packaging Web Modules(From J2ee tutorial for your information)
A web module must be packaged into a WAR in certain deployment scenarios and whenever you want to distribute the web module. You package a web module into a WAR using the Application Server deploytool utility, by executing the jar command in a directory laid out in the format of a web module, or by using the asant utility. This tutorial allows you to use use either the first or the third approach. To build the hello1 application, follow these steps:
In a terminal window, go to <INSTALL>/j2eetutorial14/examples/web/hello1/.
Run asant build. This target will spawn any necessary compilations and will copy files to the <INSTALL>/j2eetutorial14/examples/web/hello1/build/ directory.
To package the application into a WAR named hello1.war using asant, use the following command:
asant create-war
This command uses web.xml and sun-web.xml files in the <INSTALL>/j2eetutorial14/examples/web/hello1 directory.
To learn how to configure this web application, package the application using deploytool by following these steps:
Start deploytool.
Create a web application called hello1 by running the New Web Component wizard. Select FileNewWeb Component.
In the New Web Component wizard:
Select the Create New Stand-Alone WAR Module radio button.
In the WAR File field, enter <INSTALL>/j2eetutorial14/examples/web/hello1/hello1.war. The WAR Display Name field will show hello1.
In the Context Root field, enter /hello1.
Click Edit Contents to add the content files.
In the Edit Contents dialog box, navigate to <INSTALL>/j2eetutorial14/examples/web/hello1/build/. Select duke.waving.gif, index.jsp, and response.jsp and click Add. Click OK.
Click Next.
Select the No Component radio button and click Next.
Click Finish.
Select FileSave.
A sample hello1.war is provided in <INSTALL>/j2eetutorial14/examples/web/provided-wars/. To open this WAR with deploytool, follow these steps:
Select FileOpen.
Navigate to the provided-wars directory.
Select the WAR.
Click Open Module.
I guess this step is for checking my system about setup information. I not sure how to change it.

Is there anyone who can tell me how to change it? I really need your help....
Thank you in advance.ok,
First of all make sure your tutorial folder is installed from the root:
C:\javaeetutorial5
or
D:\javaeetutorial5
it makes things so simple.
Secondly:
set your jee tutorial home
JAVAEE.TUTORIAL.HOME =
C:/javaeetutorial5
Thirdly: check in:
C:\javaeetutorial5\examples\bp-project
make a copy of the build.properties.sample save it as build.propropties, as a property file,
edit the properties file as in:
build.properties
As follows:
# uncomment the property javaee.home, and add the path
# to your GlassFish Java EE 5 SDK installation
javaee.home=c:/Sun/SDK
javaee.tutorial.home=c:/javaeetutorial5
# Uncomment the property j2ee.server.username,
# and replace the administrator username of the app-server
javaee.server.username=admin
# Uncomment the property j2ee.server.passwordfile,
# and replace the following line to point to a file that
# contains the admin password for your app-server.
# The file should contain the password in the following line:
AS_ADMIN_PASSWORD=admin1234and so fourth. Some of the settings as the application server name is all done for you
and then test it again.
Take care of editing the property file. It can give you headache.
Note also that this is for application server 9.1 - JEE5.

Need SQL help in select data from 2 table..
hi,
i need some help here as i am new to sql statement
I have 3 tables.
Table1 :- TeamID, Team_Name, Team_Logo
Table2:- TeamID, PlayerID
Table3:- PlayerID, Player_Name
How do i do a single select statement that select all information from table1 and the count of playerID from table2?
My MS access table has relationships.
One team can have many players. So how do it get the numbers of player in my team?
Thanks.Thanks.
but may i know why i have to max (a.team_name)???Actually there is no need of max() here, but it must be an aggregate function to use in this context. There is no harm in using it like this. This is a work around, I didn't get enough time to work on it.
But as long as it gives correct result, don't worry about it.
btw, how do i assign duke $$ to u?
i am new to this forum.You can read at http://forum.java.sun.com/rewardFaq.jsp#assign
Have a nice weekend.

I need one helps I am implementing a tree of navigation of km with java vestibule and have a problem, when I request to him to this that orders with respect to a metadata or reality with any criterion this always takes the folders and it orders them and later it takes the Links and you order them, and the truth that I need that it does not make that distinction single that orders by the metadata that does not take in whatever if it is Link or folder

Need someone helps for several Problems on my 9630 Tour
Hello,
Well, these are list of problems with my 9630 Tour, and I need some helps to solve these :
1. My 1st problem is, everytime my 9630 started its also a message appears : "uncaught exception index 8 >= 8"
2. And I also realized that some missing application happened. My m-Banking application (already re-installed well) but it also lost of SMS icon. So the result is, everytime I sent an outgoing SMS I couldn't save it. And I have made a test to sent SMS from my other number to this 9630 device, but 9630 couldn't show that any incoming message, even my other device has given me notification that message has been delivered.
3. Its also often shutdown suddenly by itself, or its shutdown upon charging
4. Charging tasks sometime couldn't be well charged. And finally I realized that my device has off in the middle of charging task, it may caused of charging wasn't recharge the device very well
Hopefully I can read your kindly solution on those problems happened. Thank you for your prompt response.
Anwar HusseinHi and Welcome to the Community!
I actually think that all of your issues are related, and rooted in the same problem...OS corruption or hardware failure. But, before you begin, please be sure you have a good backup...see the link in my auto-sig on this post for instructions for that process.
Then, at the top of each device forum, there should be some "sticky" threads that discuss the OS levels available for many models. If they include your model, then please use those as reference as you proceed. Otherwise, you will have to dig through the official download portal for OS packages for your model:
http://us.blackberry.com/support/downloads/download_sites.jsp
From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:
http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.
You may also want to try this procedure to perhaps narrow down the precise causal item:
Load your OS "bare bones"...if anything is optional, do not install it.
If the behavior presents immediately, then try a different OS with step 1
If the behavior does not immediately present, then run for as long as it takes for you to be sure that the behavior will not present.
Add one thing -- no matter how tempting, just one.
If the behavior does not present immediately, then again run for long enough to be sure it will not have the same problem
Repeat steps 4 and 5 until all things are loaded or the behavior presents
When the behavior presents, you know the culprit...the last thing you loaded.
If the behavior does not re-present, then you know that either step 1 or 2 cured it.
If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

Some question about 9iAs R1.2.2 & R2, need your help:
Some question about 9iAs R1.2.2 & R2, need your help:
Since 2000, we has used 9iAS Core (R1.2.2) to publish our website. The platform is Suns Solaris (SPARC). The database is Oracle 8i. But there are so many questions:
1. The Web Cache cant be installed well
2. The web pages use JSP to query database with SQL show errors when we refresh the page a few times. The error will disappear after restarting the 9iAS or refreshing the page again. On the other hand, the same pages dont show error on resin. The error is java.sql.SQLException : Closed Connection: next. I supposed that the connection of database has some hidden troubles, but I can find it, could you give me some advice.
Now I have installed 9iAS R2, But when I visited the manage page, I found that a password is needed to visit the web cache manage page. I dont think I have set the password, and then I cant control the web cache. I want to know is a default password occurred? If not, what is the password.The default password for Web Cache is: administrator
See walkthrough on the sample code page: http://otn.oracle.com/sample_code/products/ias/content.html

Need urgent help with Ifs1.1 on Solaris
We have installed IFS 1.1 with Oracle 8.1.7 on a three tier System (two Suns). We use JWS as WebServer. When we start IFS and JWS everything seems to work fine. But after some time (irregulary) we are not able to contact the JSP-Sites via a bowser. After restarting JWS, everything works fine for some time.
Sometimes it happens (about one times a day), that the whole JWS crashes (JWS-Admin doesn't work). So we have to restart the whole IFS.
What can be the problem? We need urgent help, because the deadline for our project is Wednesday.
By the way:
Where do I have to start CTX on the IFS- or the Oracle-Side?
nullYes, we tried the Oracle HTTP - Server, but we weren4t able to get it to work. We didn4t get our JSP-Files to work with it. But that is another issue. I think it4s not a problem of JWS, but IFS.
Additionally it is strange, that we are still able to connect to the database via SqlPlus.
IFS works fine for about 15 minutes, than it crashes, nothing works anymore. We found following errors in the IfsAgents.log:
maybe it can help?!

}Hello I am new to java, and I hope someone help me to modify the above code in order to make it work as the following:
I have a list of integer values like 1, 2, 3, 4? 10
And I want the program to substitute the integer values (the integer declared list) subsequently one by one to output a new html file as the following output:
This is written to a file 1
This is written to a file 2
This is written to a file3 ?etc
Also this substitution has to be outputted to a new file every time.
Thank you very much in advance for your kind help
if i have to post this anywhere else please advise me..

Remote App on iPad connects but drops after about 20 mins. Need to turn off wait about 1 minute, then turn on wifi on iMac before it can reconnect. Need some help please.
Already gone through troubleshooting guide a zillion times. Thanks.This worked for me... A little time consuming but once you get rolling it goes GREAT... Thanks....
I got my artwork and saved it to my Desktop
Opened up Microsoft Paint and clicked on "File" and "Open" and found it to get it on the screen to resize it
Clicked "resize" and a box for changing it opened up
Checked the box "Pixels" and "Unchecked maintain aspect ratio"
Set Horizontal for 640 and Vertical for 480
Clicked on "OK" and went back to "File" and did a "Save As" and chose JPEG Picture
It came up "File Already Existed" and clicked "OK" (really did not care about the original artwork I found because wrong size)
Went to iTunes and on the movie right clicked on "Get Info", clicked on "Details", then "Artwork"
Go to the little box on the top left that shows your old artwork and click on it to get the little blue border to appear around it and hit "Delete" to make it gone
Click on "Add Artwork" and find it where you put the one from above on your Desktop and hit "Open" and OK and your new artwork is now there and all good.
Sounds like a lot of steps to follow but after around 5 or so you will fly through it. This worked perfect on my iPhone 6 Plus and I have artwork on my Home Videos now. -
Need your help in Remodeling concept
Hi Gurus need your help in time estimations
I have a cube with data and now I need to add 10 new info objects to the cube which are including Date fields (BUDAT, BLDAT) these 10 fields will be populated to the cube from a Z table in ECC as we donu2019t have these fields in the cube we have to go for remodeling of the cube
My client requires how much time it will take to complete this
Now I want to know how much time it would take to do this (if any customer exits and user exits are required) and addition if new fields will have any effect on the current queries
Please advice in this
Thank youThe time taken will depends on a lots of factor like server speed, available memory, background jobs etc. Apart from this, the time will also depends on how much the cube is filled i.e. the no. of records in the cube. Its very abstract to tell you the exact time taken for this. But, please make sure that you have the backup of the cube which you are going to re-model. T0 say, I think 3-4 hours should be ok for the remodelling.
Thanks.

Need your help on performance issue please
Hello everyone!
I need your help to understand an effect I notice with a Thread class I built. I currently work on enhancement of my application Playlist Editor (see http://www.lightdev.com/page74.htm) and a new release will be available soon.
Among other extensions the new release will have a title filter function which is based on audio data that is recursively read from ID3 tags of files found in a given root directory. The data collection is done by a CollectionThread class which reads into a data model class AudioDataModel and the entire process works fine, no problem with that.
However, when my application is started for the first time the CollectionThread runs approximately 3 minutes to collect data from approximately 4300 audio files on an Intel Pentium M 1,4 GHz, 512 MB RAM, Windows XP SP2. When the application is shut down and started again, it takes only a few seconds to do the same task for all subsequent launches.
I already tried to start the application with java option -Xms40m to increase initial heap size. This increases performance in general but the effect is still the same, i.e. first run lasts significantly longer than subsequent runs.
I also tried to build a pool mechanism which creates many empty objects in the data model and then releases them to contain the actual data at is being read in but this did not lead to better performance.
It must have to do with how Java (or Windows?) allocates and caches memory. I wonder whether there is a way to pre-allocate memory or if there are any other ideas to improve performance so that the process always only takes seconds instead of minutes?
I attach the key classes to this message. Any help or ideas is much appreciated!
Thanks a lot a best regards
Ulrich
PS: You can use the news subscription service at
http://www.lightdev.com/dynTemplate.php4?id=80&dynPage=subscribe.php4 to be informed when the new release of Playlist Editor is available.
All classes posted here do not need debugging, they already have proven to run error free. The classes are only posted for information for the interested reader - no need to go through all the stuff in detail - only if it interests you.
My application calls class CollectionThread wich is a subclass of InfoThread. CollectionThread recursively goes through a directory and file structure and stores found ID3 tag information in instances of class ID3v11Tag which in turn gets stored in one instance of class AudioDataModel. All classes are shown below.

*Hi Franck,
thank you, mate. I did what you suggested (changed class attached) but that did not change the mentioned behaviour.
The first run is approximately 75 seconds with Java option -Xms40m and approx. double without, the second run and all subsequent runs are only 2-3 seconds each (!!!) even when terminating and re-starting the application between thread runs.
I'm pretty clueless about that, any more help on this anyone?
Thanks a lot and best regards
Ulrich
