Database connection + punnk = never going to happen

I downloaded Tomcat 4.1 and the JSTL 1.0.6 tags(myApp/web-inf/lib) - everything seems to be in
place and working. I have my commons in the common/lib(for now). I added a system DSN.

It's probably my fault but I have no idea what to do - I have followed the instructions time and time again and it doesnt work for me.

sci - Yikes? Really what about that didnt you expect?
I dont appreciate you demeaning all the hard work that
I have put into this project with the snide comments
you made. I am not a student expecting you to do my
homework for me nor do I expect anyone to do my work
for me.I didn't demean anything.
I certainly did not demean your efforts or duffy's efforts to help you.
I did state a couple of facts.
1) You seem to be over your head in places and this is probably 99% of the problem. This is NOT demeaning to you or anyone else. No one expects you to learn everything about everything in one week. It is not realistic though to put expectations like that on yourself or count on help from others when you are still struggling with some basics.
2) Both you and duffy seem to have some frustration on this. What I said about duffy going to you and fixing this in person in this time is true.
I am also aware that this has been frustrating you though... your subject line for example database connection + punnk = never going to happen certainly seems clear about this.
>
If I jump around in my questions its because I am
trying to figure out what I am doing myself. No I dont
know what I am doing yet - but I am learning. Give me
a break, huh?And what I am suggesting is to give yourself a break too.
Chunk your learning into pieces more realistic for you at this point.
Not because you are annoying me, which you are not, but even if you were it wouldn't be relevant.
Because you don't seem to be making progress so maybe it's time for a step back and taking a different tack. You may disagree with the route I suggest but I think it behooves you to at least consider it.
>
I dont know much about java but I do still know how to
read. And if you are this frusterated with me asking
questions perhaps you should think of how I feel. ItsAs stated above your frustration is why I am suggesting you try to be realistic in your learning and development.
my ass on the line here not yours.
Okay. That's your problem though. Why would your ass be on the line about this? No company can realistically expect someone to deploy something using technology new to them in a matter of days. I suppose it happens but it isn't realistic.

i tried to up date my i phone 4 to iOS 5 then it wiped my phone and now it tells me to connect to iTunes and that the iPhone is in recovery mode and when i connect it goes to preparing to install to iPhone but never goes any further how do i restore the phone

by reset option do you mean the DFU restore? worked for me, have you tried that?
if not - hold the lock and home button until the power down bar comes up. then hold the lock button for ten seconds - next continue to hold the lock button and press the home button for ten seconds - next release the lock button and hold the home button for 10 seconds. this should be done with the phone tethered. If done right and your itunes is configured as such, the phone will reload the drivers and start up itunes, and then prompt for a restore/update.

Hi, I have the iPhone 4, 32GB, version 4.3.5 (8L1) and for some reason when I connect it to the laptop, it starts synchronising but never goes beyond step 1. It goes on syncing forever, without actually doing anything. I have tried everything, wiped the phone numerous times, deleted all files from the laptop but still no resolution. As a result, the phone does not really synchronise.
This started somewhere in May 2011 when I upgraded what proved to be a problematic s/w version and the phone has not recovered since.
Now I cannot update the iPhone s/w any longer.
Any clue?

You may have to try deleting all the music from your phone (by going to Settings>General>Usage>Music, swipping All Music and tapping Delete), then sync it all back on with iTunes in order to fix this.

Ever since I installed Lion my internet connection comes and goes, has anyone else had the same experience. have rung Apple Care and they have reset my connection but it is still happening

ever since I installed Lion my internet connection comes and goes....have reported this to Apple Care who have helped me reset my connection but it is still happening...cant believe it is a fault of the ISP as my Iphone does not have this problem, nor does my PC laptop...is this a fault in the new system?

Thanks so much but none of that helped. It was driving me crazy because it would back up another external drive. I just changed the name of the drive from iPhoto/iTunes Library to Media Libraries and IT WORKED!! I guess for some reason it didn't like the drive being called iPhoto or iTunes ???? I don't understand but I have tried so many solutions and exchanging things out but the name change did it????!!!
Thank you for your help and replying to this. Guess I made my own issue!

My iPod classic shows that memory full in other category however there is nothing on it. I have left it connected all day and over night trying to restore it but the progress bar never goes away. Is it shot or are there other options to restore to factory settings?

Hi pbworth,
When troubleshooting issues with iPod classic, it may be helpful to place the iPod into Disk Mode. For information on how to do so:

Hard Drive connected - Space Available never goes down when deleting files?

I have tried 2 different USB drives connected to the new airport N router.
Both drives work fine, an 80 GB maxtor, then replaced it with a 500GB usb seagate drive. Both drives have the same problem.
I only hook one drive up and copy over files to the drive. The space available shows up fine, but when I delete any files, the space available never goes down.
Any ideas how to fix this or is this just a nice big glitch?

Anyone with a hard drive connected to the N router.
Just copy some files the drive, then delete them while watching space available. The space available never goes down. What gives? Anyone else seeing this problem?

Hello JBH 1162
Check out the articles below to get your iPhone to show up in iTunes so it can be restored. Start with the first one to see if you can make any change to show up in iTunes and if it does not, then pick either the second or third article for the type of computer that you have.

Question regarding Database Connection.

Normally, after we open a database connection, we could use the Connection.close() method to close and return database connection back to a connection pool.
What would happen if I nullify the connection without using the close() method to close a database connection?
Would the database connection automatically close after I nullify it?
If not, how the connection going to return back to the connection pool?

The connection will close/be released automatically when the garbage collector runs, but you should NEVER rely on that because you never know when the GC will run or if it will collect all objects or only part of them. Best approach is to always have a finally block where you close/release the connection.

Why do I get a class conflict between the Prepare SQL.vi and the Get Column Name.vi with the SQL Toolkit compatibility vis from the Database Connectivity Toolkit?

I have done extensive programming with the SQL Toolkit with LabVIEW versions through 6.1. My customer now wants to upgrade to Windows 7, so I am trying to upgrade to LabVIEW 2009 (my latest purchased version) using the Database Connectivity Toolkit, and the SQL Toolkit Compatibility vis. Everything seemed to be going okay with the higher level SQL operations, but I ran into trouble with the Get Column Name.vi.
The pictures below show the problem. The original SQL Toolkit connected the Prepare SQL.vi with the Get Column Name.vi with a cluster of two references, one for connection, and one for sql. The new compatibility vis have a class conflict in the wire because the Prepare SQL.vi contains a cluster with connection, and command references, but the Get Column Name.vi expects a cluster with connection and recordset references.
How do I resolve this conflict?
Thank You.
Dan

I've never worked with the old version of the toolkit, so I don't know how it did things, but looking inside the SQL prep VI, it only generates a command, and the the column name VI wants a recordset. I'm not super familiar with all the internals of ADO, but my understanding is that is standard - you only have the columns after you execute the command and get the recordset back. What you can apparently do here is insert the Execute Prepared SQL VI in the middle and that will return what you need.
I'm not sure why it worked before. Maybe the execute was hidden inside the prep VI or maybe you can get the column names out of the command object before execution. In general, I would recommend considering switching to the newer VIs.

Proxy functionality in the database connection pool

Hi,
I am scouring the internet and forums looking for a way to connect to my database from the .rpd connection pool using proxy authetication. NOT Act-As proxy that is a BIEE feature, but RDBMS proxy authentication with BIEE acting as the middle-tier connecting on behalf of many users and authenticating to the RDBMS AS THE INDIVIDUAL USER. I haven't had any luck, and am hoping someone here has set up this same kind of access.
We have a requirement to use SSO with BIEE to integrate with our portal and discoverer apps. We also have a requirement to use EUS (Enterprise User Security). EUS allows you to login to the database using the userids/password from OID. Note that the database doesn't support the SSO token, but it uses the same userid/password stored in OID for authenticating to the database. You still must initiate a connection to the database, but the authentication goes to LDAP. Every connection to BIEE may be using a different userid - we will not have a shared login.
So the issue I see is:
- We configure SSO
- In the BI Server the :USER session variable is set (but NOT :PASSWORD, since BI Server didn't authenticate you it doesn't have the password)
- We create a connection pool - This is where we hit the issue - we need each connection to BI Server to connect down to the database as the SSO user. Since we aren't using a shared account we can't enter a userid/password in this connection. We also can't user :USER and :PASSWORD since SSO doesn't set the :PASSWORD session variable. What I would hope to find is a checkbox "Proxy Authentication" (around where "Shared Logon" checkbox is located) that would connect to the database as the proxy user and then switch to the SSO user.
This is what happens with BI Publisher. On the JDBC connection screen there is a "Proxy Authentication" checkbox.
So, has anyone already solved this problem? Thanks!

Hello, is there anyone knows what this program does
and how this program is executed? There is nodatabase
mentioned.That's because it's expecting the URL (which contains
the database type, hostname, and so on) to be passed
in on the command line (argv[0]), as well as the
username and password (argv[1] and argv[2]).
Thank you very much for your help.

Itunes says "update complete" but "do not disconnect" never goes away!

So, I wait and wait and "do not disconnect" on my ipod never goes away.
A little history:
I got my nano a few weeks ago, put a few songs on - everything worked fine. Then, I got a new computer. Since I only put a few songs on, I didnt mind starting from scratch. Now, I can't seem to get it to work!? I have songs in itunes. when i click on my ipod, it shows that i have songs on the ipod, it SAYS the update is complete, my ipod shows "do not disconnect" i wait for ages, and then finally just eject the ipod, and - NO SONGS are on it.
help please. thanks
Windows XP Pro

Do not disconnect always on, this happens when you have "enable disk use" ticked in the iPod preferences, in which case you have to manually eject your iPod.
However if you are automatically updating your iPod and do not intend using it as a portable hard drive, you can set your iPod to automatically disconnect.
Connect your iPod and in iTunes go to Preferences>iPod. Under the Music tab see if you have your iPod set to automatically sync with iTunes and also have a tick in the box marked “enable disk use". Remove this tick and your iPod should automatically disconnect after it’s finished updating.
If you have your iPod set to manual update, the box will be greyed out and ticked by default, in that case use Safely remove Hardware icon or check this link: "Disconnecting iPod from your computer

Tomcat JDBC Realm Database Connection Error

Hello all,
I am trying to edit the server.xml file on Tomcat so I can use the JDBC Realm instead of the MemoryRealm. Hence, I will be able to read users, passwords and roles from a relational database instead of from the tomcat-users.xml.
I have tried following all the guides on the net I can find, my server.xml looks as follows (after making changes to allow it to use JDBC realm). The only problem is, when I try to run the application the server outputs the following: (after all of these errors have been kicked up a pop-up box then appears titled "Tomcat Manager Application", it asks for a User Name and Password. I have tried the standard user name of "ide" and the password next to it in tomcat-users.xml but it won't accept it. (I am using the netbeans IDE)).
Please could someone suggest any ideas of how I can get the server.xml to work with JDBC realm?

So looking through the java api docs, I found that the tcUtilJDBCOperations has a connect string for the database. Below is the info it outlines. The questions I have it this. How do you specify the psdriver and URL along with do I need to do this as a persistent instance then add my selectstatement as a part of this or can I just specify this and the select statement will use this connection? Any help you can give would be appreciated.
tcUtilJDBCOperations
public tcUtilJDBCOperations(java.lang.String psDriver,
java.lang.String psUrl,
java.lang.String psUsername,
java.lang.String psPassword)Contructor that sets the parameters for connecting to a database
Parameters:
psDriver - The class name of the jdbc driver
psUrl - The URL of the database
psUsername - The username required to access the database
psPassword - The password for the above username

Database connection + punnk = never going to happen
