I need a JTable expert

hi room, if there are any JTable experts, can they help me please? I have a very complicated problem, so far no one knows a workaround, so I need a real expert on this topic. Thanks in advance.

It's usually easier to answer the question if you ask
it first. Do you think we are mind readers?sorry.
I needed time to write my question.
Bascially, what I want to do is I want to query my database and display the results on my screen. The problem is, the query might be different each time. It might well be that the first query returns two string data items. I will need to display these on one row in two columns. But the next query might return five data items, three are which are strings, one an image, and one another string. I will need to display these as one item on the first row, two strings on the second row, one image on the next, and another string on the last row. Basically, what I am trying to say is the dimensions of the table will change with each query. Thesefore I cannot just create my table once, and fill it in each time. I will need to create a table each time.
Also, this is complicated because this table will not have an equal number of columns on each row. The first row might have two columns, each with one string, and the next row might have only one column which contains an image.
maybe the following diagram might better explain a possible table.
|.....................|..........................................................................|
|.....................|..........................................................................|
|_________|________________________________|
|................................................................................................|
|................................................................................................|
|................................................................................................|
|................................................................................................|
|................................................................................................|
|_________________________________________|
As you can see, this table has two rows. The first row has two columns, and the next one has only one.
Also, there are no headers,
Basically, I am not even sure if I need a JTable. I really just need cells that are all joined together.
So if there are any JTable expers out there who have undertaken such a project before or know someone who has, please help me cos I have been stuck on this bit for over a week now and this is getting me depressed, so please help me, I will one day repay your helpfulness in other ways.
Thanks.

JTable Experts Needed :-)

Hello JTable Experts,
I have to build a planning application whose one screenshot is below.
http://nicolasjouve.free.fr/public/sample.PNG
My question is : should I use a JTable and customp 2D painting, or should I go for full Java2D ? I have to add that you may drag one card from a slot and put it in another one. Please note the mutiple lines header and multi column left header and the "cartoon like" captions in yellow....
Thanks in advance,

Well I don't see any huge features in your screenshot that would be too hard to implement.
Basically the column and row header are not supported by standard JTable (colorizing stuff is easy).
I would advise to use separate JTables for row and column headers (in additioin to main table), so you will need to synchronize scrolling. But this could be done. No need to make a custom component.
If you decide to design a new component, be sure to take the JTable source code and modify it (the best way is subclassing the existed classes).
Creation of new component from scratch could be quite difficult especially if you want it to be consistent with different LAFs.

I need a MacBook experts, master to help me!!! I just tried the craziest move on my mac! My dad's gonna kill me if he finds out!!!

I need a MacBook experts, master to help me!!! I just tried the craziest series of moves on my mac.
Begun when the mac hung for nearly an hour. I held the power key to force a shut off.
This made me think of erasing some things on my hard drive. I used cmd r for disk utility and begun erasing volumes.
Then, I thought instead, why not just reinstall OSX since nothing I wanted was on it.
I tried to reinstall OSX but this time it loaded then suddenly said, an error occurred.
I Went back to disk utility and cleared stuff I can't even remember.
Another unbelievable thing happened. The disk utility actually hung for a good ten minutes! i went and forced a shut off again.
Now, whenever I turn the mac on, a flashing folder appears.
at this point, I usually turn to the net for answers.
Greatest thing is, every cmd something I try doesn't even trigger a reaction. Only cmd opt showed my mouse cursor.
i Do not have the original OSX install disk for my mac. Any geniuses got any clues???

Your post somehow found its way to a low-traffic forum about technical issues with posting in Apple Support Communities. I have asked the Hosts to move you to a more appropriate hardware forum for your product.

Help needed in JTables

Hello,
Can any one help me in a small question.
I use JTable to display some values it is a two dimentional table.
Now can any one tell me how to put an icon in to a particular cell of the table
it may be and cell.
Best Regards,
Sreedhar

You can use a custom TableCellRenderer to do this. There are good examples of doing this in the JTable lessons in the turorial on this site. To put icons in particular cells you need to define the conditions where a icon should be displayed and then code that logic into your renderer.
After you have read the tutorial and started on your own renderer post specific questions.

Help needed on JTable

I am trying to create a table, i know how to create my own table model, using abstractTableModel. I dont need my own cellrenderer, because i will just be using text in my table's fields.
I am adding my data, which i read from a database, into a vector, when i create my table model.
I am under the impression, that if i want to get a new set of data from my database, and display it in the table, i would first have to kill the current table object, and recreate it, by so doing, i will get the new resultset in my table.
I have looked around on the net, and people mention things about eventlisteners, which shoud do this?....
Please advise me?
Thanks

When you've added/replaced the data in your tableModel call:
yourTableModel.fireTableDataChanged();
to see the changes in the JTable.

Need advise from experts : APEX & Search Engines

Dear Experts,
I need one advice. I intend to develop my site in APEX. But I am not sure if a site made in APEX will be crawled & indexed well by the search engines so that it appears when somebody is searching for the related information.
Can anyone please enlighten ?
Regards,
Ashish Agarwal
http://www.asagarwal.com

Patrick,
Don't worry, I didn't take it personally ;) Just wanted to point out that using the site directive can give different results (or perhaps the same results in a different way) to a plain old 'type in a name' search.
We do use Session 0 on the Apex Evangelists site (for example in the initial link to the home page), however when you navigate to the login page a new session id is generated (which is why that has been indexed multiple times by Google), also some other pages (for example the EuroTraining page have been indexed multiple times due to external links to our site referencing a link which already has a session id, rather than using the alias for it).
You're right you can spend a huge amount of time tweaking and cajoling things to increase your page rank in Google (and other search engines of course), infact I know companies that specifically employ people whose sole job is SEO. You're right, there are still things we can do to make the indexing a bit better. However for our purposes (at that time), the fact that the login page etc are indexed multiple times (for various reasons) doesn't 'hurt' us too much, we saving those changes for the next release of the site ;)

MS 2008R2 networking issue? Need MS network expert to advise on virtual IP address vs IP address on mirror servers

I am not a network engineer or MS network expert, but have spent many hours researching docs and sites without a clear reason to explain
the situation.
I have a client with 2x 2008R2 mirror servers. When the app fails, the primary server switches to secondary server as usual; however a connecting Unix application (on another segment) somehow cannot see the Virtual IP at that point and the situation is disastrous.
The IP (v4) for server A is x.x.x.10 and server B is x.x.x.11 whereas the VIP is x.x.x.99.
Reading hordes of MS related docs it seems the answer is to avoid having the the VIP larger that the server IP addresses, meaning the VIP be x.x.x.9 or smaller. The Unix application now connects successfully as the failover on the MS servers flip-flops.
Is this due to RFC 3484, Default Address Selection for IPv6 (February 2003) rules being imposed on ip4 as implemented? If so which rule and can you explain is digestible manner?
Or OTOH this is a MS default of take the smallest IP number bound to the card as the primary outbound address (this I understand is how it was pre 2008R2)
Or is there something else I have missed?
Most importantly, anyone know the Microsoft kb issue reference?

Hi,
Regarding to the description, I suggest you move the Unix application (on another segment) to the same segment as the mirror servers'. It will avoid some factors from middle devices. As you have the issue only on the Unix application.
If we need to know why the failover is not working well when apps fails. We could gather the netmon traces between the servers to verify which one reject the request.

There are too many mistakes in your program. It looks like you are new to java.
Your add and delete row buttons are not working because you haven't registered your action listener with these buttons.
I have modifide your code and now it works fine. Just put some validation code for the textboxes becuase it throws exception when user presses add button without entering anything.
Here is the updated code: Do the diff and u will know my changes

Need a security expert to help on this one...

Hi
I have recently deployed a 3-tier **proprietary** application that:
- has a thick-client installed on a Windows Vista client machine
- Oracle 10g Enterprise edition version 10.2.0.1.0 installed on a server running Red Hat enterprise Linux. This is a very
cut-down version of Linux, only accessible through SSH (or by directly plugging in a keyboard+monitor into the linux box). It
does not have any GUI/windowing mechanism installed on it at all (so for example there is no 'xclock' installed in this
linux). Also the oracle server software installed here does NOT have Oracle Enterprise Manager installed.
I have complete access to the server and can log in as sysdba via SSH (simply login to a SSH terminal and then type in
'sqlplus "/ as sysdba" - that lets me in as the SYSDBA.
Problem: I want to use a graphical tool like Oracle Ent. Manager to look 'inside' the DB. But I cannot install anything or
play around much with the linux box, but I can do whatever I want to the client vista machine.
Attempts so far:
Looking around inside the installation on vista client machine I discovered a folder:
"<xxx>\3rdParty\Oracle10g" which contained files:
- tnsnames.ora
- sqlnet.ora
- sqlplus.exe
When I ran this sqlplus.exe on a CMD prompt it said:
Error 6 Initialising Sql*Plus
Message file sp1<lang>.msb not found
SP2-You may need to set ORACLE_HOME to yourr oracle software directorySo I installed Oracle 10g Client (10.2.0.1.0) on the Vista client machine, hoping that I will then be able to use OEM on
this vista machine and connect to the oracle running on the linux box.
On the vista box I also did:set ORACLE_HOME=C:\oracle\product\10.2.0\client_1
Now I ran the sqlplus.exe (on the vista box) again and it came up with a login prompt. Problem is I dont have a
login/password; what I plan to do is to create a user by logging in as sysdba on the server, and grant all access to him, and
then log into Oracle Ent Manager as this user from the windows machine.
However, here is another problem: if I do 'tnsping <my_db_name>' it says:
TNS-12541: TNS:no listener
I suspect this is because of some security setting in this application OOTB.
The entry in tnsnames.ora setting is correct, as it was done by the client install program (not manually). It contains:
PROTOCOL=TCPS, and PORT=2484.
There is also a 'wallet' folder on the client machine under 'Oracle10g' folder.
Finally the sqlnet.ora on client machine contains:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
SSL_VERSION=0
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
SSL_SERVER_DN_MATCH = FALSE
SSL_CLIENT_AUTHENTICATION = TRUE
WALLET_LOCATION=
(SOURCE=
(METHOD=FILE)
(METHOD_DATA =
(DIRECTORY= C:\<xxxxxxxxxx>\Oracle10g\wallet)
SSL_CIPHER_SUITES=(SSL_RSA_EXPORT_WITH_RC4_40MD5)
All I would like to do is to be able to connect to the oracle server with tools I am familiar with (like OEM, TOAD etc.).
This stuff is quite outside of my understanding, so if you can provide any insight it'll be much appreciated.
Thanks

You could try syncing the contacts with yahoo or google contacts, then sync them to the iPhone. Or, export the contacts and then import them into one of the aforementioned servicse, or iCloud, then sync to the phone.

does any of you can read what i wrote in my source codes and let me know what i missed in my html map code : BIMapPage.html and where or how i can get two parameters values URLParamNQID

yes i checked this site, but i still couldn't reach the answer of my challenge, in how to specify urlParamNQID and urlParamSID , how or where i can get value of these parameters or what should i pass there !?

I need a Flash expert to help me urgently!

This is a long shot and forgive me if I'm posting in the wrong forum-
I am a web designer and I have a client who has asked me to do a project for him very quickly in Flash. He's given me a template and, whilst Flash isn't my strong point, I've been fine customing it for him as he wanted it.
But now I'm totally stuck because he wants me to work with the action script and I've come completely unstuck. If I was working in Dreamweaver I'd be fine, and I have a feeling the problem would be a piece of cake to a Flash expert.
Is there anyone who could spare me 10 mins of their time? I could zip up the template and let them have a look at it?
If this is the wrong place then can someone suggest somewhere I else I could go?
Be kind to me!
Claire

let me look at your file
Can you give me the file
I will try to help you But don't be sure i am middle level AS3 and i am learning form this forums.

In need of an expert: OpenGL and drawing simple textures

Hello,
Is anyone knowledgeable about loading sprites with an alpha channel?
This is the code I am using to load my sprites. The image files were png files with an alpha channel(parts where you can see through the image). But when loading it the parts that are supposed to be invisible turn out to be black.
I have searched far and wide across the internet and what a surprise I only see solutions for mobile phones other than the iphone! It would be great help to the iphone community if someone can be kind enough to point out what it is thats supposed to be done to get this to work.
{CODE}
myTexture = Texture2D alloc initWithData:data bytes pixelFormat:kTexture2DPixelFormatRGBAPVRTC4 pixelsWide:512 pixelsHigh:512 contentSize:CGSizeMake(512,512);
{CODE}
then running the following in drawView:
{CODE}
myTexture drawAtPoint:CGPointMake(0,0);
{CODE}
the result is the texture showing correctly except the invisible parts turn out black. Perhaps I have to set something in the drawView? Please If anyone out there can help.

You may need to enable alpha blending systemwide, e.g. glEnable (GL_BLEND), as well as glBlendFunc(), glAlphaFunc(), etc.
