MySql with mm Driver experience???

Folks.... this is drivin me NUTZ!
I have an application which opens one connection to a MySql database. Now, I have about eight classes that use this connection to obtain result sets. I have one class that obtains six result sets. All of them are scrollable and updatable. One does not work, although I set it up exactly as I do the others. An exception occurs when I try to move to the insert row of the set. It says it is not updatable. This is all single thread stuff. I tried getting the concurrency and type from the created statement, and always get 0's for both.
Can someone pont me in a direction?
Help!
sfav

I remember having a problem like this when I set this database up.
I dont know how you set up your connection but I had to drop the user name and password as
follows.
Did you try inserting values into your tables from the command prompt .
try{
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
connection = DriverManager.getConnection("jdbc:mysql://localhost/OTI");
// previously used username and password
// "jdbc:mysql://localhost/IOT?user=usernameo&password=**********");
Please post your resolution to this problem .

  • Problem with JDBC driver for Oracle 10g

    Hi.
    I've successfully accessed a MySQL database via a DataSource from a servlet (that uses a DAO). However, when I try to do the same with an Oracle 10g Database, I get the error message:
    Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
    I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter of which I downloaded this afternoon as the latest driver JAR available on the Oracle site. As with the MySQL driver, I've placed it in the commons\lib folder within Tomcat. (I've also, of course, made the necessary modifications to server.xml and web.xml.)
    Upon examining the ReadMe file at the top of the Oracle download page, I found that the oracle.jdbc.driver package is now deprecated and all references to oracle.jdbc.driver should be replaced with oracle.jdbc. However, I got a similar error message when I tried this modification. Upon examining the contents of ojdbc.jar, I found that the driver was there and that it was, in fact, still oracle\jdbc\driver\OracleDriver!
    It appears as though the Oracle site has not been updated with a driver that matches its latest documentation. However, this does not explain why the driver is not even being loacted when it is in the correct place. Can anybody shed any light on this? Any help would be much appreciated.
    Thanks in anticipation.

    That's different from a ClassNotFoundException.

    of which I downloaded this afternoon as the latest
    driver JAR available on the Oracle site. So you got ojdbc14.jar or ojdbc14_g.jar under the 10g drivers?
    As with the
    MySQL driver, I've placed it in the commons\lib
    folder within Tomcat. I think it's a better idea to put in the WEB-INF/lib directory of your Web app rather than commons/lib. WAR files are a very good idea, too.
    (I've also, of course, made the
    necessary modifications to server.xml and web.xml.)So you're using a JNDI data source? It sounds to me like that's where the problem is.
    You should not have to edit the server.xml at all. If you put the <ResourceParams> in a context XML file with the same name as your WAR file into the TOMCAT_HOME/webapps directory it'll be picked up automatically. (It might also be accessible in the META-INF directory for your app, but I haven't done it that way.)
    Upon examining the ReadMe file at the top of the
    Oracle download page, I found that the

    examining the contents of ojdbc.jar, I found that the
    driver was there and that it was, in fact, still
    oracle\jdbc\driver\OracleDriver! The fully-resolved class name you should be using MUST match the class that's in the ojdbc14.jar that you're using. Look in the JAR for the definitive answer: the one that I downloaded is still using the oracle.jdbc.driver package for OracleDriver.class. Ignore the docs - use the name that's in the JAR.
    It appears as though the Oracle site has not been
    updated with a driver that matches its latest
    documentation. That often happens with docs.
    However, this does not explain why the
    driver is not even being loacted when it is in the
    correct place. Can anybody shed any light on this?
    Any help would be much appreciated.I think the problem lies in your web.xml and server.xml
    I'd recommend that you decouple the JDBC from the Web app for now. See if you can connect to Oracle using a simple desktop app and leave the Web piece out of the equation for now. Once you can do that, you'll be certain that the parameters you're using are correct and you can turn your attention to getting the Tomcat configuration right.
    PS - I'm using Oracle 9.2.0.1 and Tomcat successfully right now, so it can be done.

  • MySQL - Connection Pooling - Driver?

    Hi there!
    I am looking for a JDBC 2.0 compatible driver to use with MySQL. I would like to use connection pooling in a webapplication (JSP:s and Servlets) but I have just found out that the driver I usually use mmmysql do not support connection pooling. Hence, my question: Where can I find a driver to use with MySQL with support for Connection Pooling?
    bw

    have you tried resin..
    http://www.caucho.com/projects/jdbc-mysql/index.xtp
    i haven't checked it yet but it could be an option
    i'm currently using mmmysql driver also...I tried that driver and when I had more than one statement open at the same time, it gave me garbage results and then threw an exception. So I'm using the mmmysql driver too.

    create mysql databases?
    You are more than a bit confused so please stop here until you understand the following.
    JDBC is the API for communicating with relational databases in Java. It is not a database in and of itself but it can communicate with any database that provides JDBC API access in the form of a JDBC driver.
    Also, I would like to know of a good tutorial that
    teaches MySQL with java.The Sun tutorial on JDBC may be found here http://java.sun.com/docs/books/tutorial/jdbc/index.html
    Your using (or not) MySQL is not relevent on this forum and any questions you have regarding MySQL (with the exception of one) are beyond the scope of this forum.
    The exception is "Is there a JDBC driver for MySQL and how do I use it". The answer to that question is yes and see this http://www.mysql.com/products/connector/j/

  • Configuring mysql with J2EE

    Hi Im a newbie in J2EE. (just started learning it 2 days back that new..;-)
    I managed to set up a simple application using the J2ee tutorial. Now i want to try out a database application. I have a mysql database installed. Can anyone guide me on how to setup mysql with j2ee server? Are there any online tutorials etc that would help me in this?
    I actually managed to create a connection pool however when i try to ping it i get an error message with says "An error has occurred. Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Class name is wrong or classpath is not set for : org.gjt.mm.mysql.jdbc2.optional.MysqlDataSource" .
    I hav already set classpath of mysql driver. Do i need to copy the jar file to any other directory?
    Im not too sure if the way i have created connection pool is right, but i used the defaults specified so i guess that should be ok.
    Any Help would be appreciated.
    Thanks in advance.

    Hi! I�m Brazilian and I�ve been learning the English language yet, but I�ll try to describe how to configure J2EE with MySQL.
    I am using MySQL version 4.1.7 with J2EE version 1.3 on Windows XP Professional. The driver version of MySQL is 3.0.16.
    You have to configure the following two files:
    - <J2EE_HOME>\bin\setenv.bat
    - <J2EE_HOME>\config\resource.properties
    Do the following steps:
    1) Copy the JAR file of MySQL driver (mysql-connector-java-3.0.16-ga-bin.jar) to <J2EE_HOME>\lib directory.
    2) In <J2EE_HOME>\bin directory open the setenv.bat file and analize the code. It is not hard to understand the code, it is just the classpath configuration of J2EE. After understand it, add a reference of MySQL driver (mysql-connector-java-3.0.16-ga-bin.jar), that was copied to <J2EE_HOME>\lib directory.
    3) Run the <J2EE_HOME>\bin\j2eeadmin.bat to configure the resource.properties file.There are two command lines to be executed, as below:
    - j2eeadmin.bat -addJdbcDriver <CLASS NAME OF THE DRIVER>
    - j2eeadmin.bat -addJdbcDatasource <JNDI NAME> <URL>
    For example:
    - j2eeadmin.bat -addJdbcDriver "com.mysql.jdbc.Driver"
    - j2eeadmin.bat -addJdbcDatasource "jdbc/mysql/test" "jdbc:mysql://localhost/test?user=username&password=pass"
    4) After run j2eeadmin.bat, the resource.properties file will be modified. But when I did it and when I executed the verbose command to start J2EE, some error messages was exhibited. So I decided to open the resource.properties file and I noticed hat the character "\" was added erroneously in a lot of places of the code. It did not seem correct, so I decided to remove these characters replacing them. Bingo!!! After I did it, I run verbose again and no more message error ocurred. I think it is a bug of J2EE.
    Finish! I modified the datasource JNDI to access MySQL and then I run my EAR application. No problems occurred. My application is running succesfully.
    Good luck!

  • USB 2.0 Problem with Hard Drive

    Hi
    I bought a new iBook this week, and have been itching to use USB 2.0 for my external hard drive. Unfortunately, when I try and copy my music from my external hard drive to my Mac, the computer hangs and crashes the system. After I reload, the folder I try to copy is sitting on the desktop, and sometimes there is one or two files, but they are unreadable. I have recently reformatted my hard drive so I know the hard drive is OK, and have verified the disk just to be sure. Fortunately, I can still copy files from my hard drive with Firewire, but it's incredibly irritating, as you can imagine.
    Anyone have any ideas on the reason for this?

    Small update on this. I have fiddled further with the drive and discovered that I can copy files TO the drive, but not FROM the drive. Any kind of file I copy hangs the system, forcing me to either unplug the drive or force restart.
    The drive otherwise works fine with Firewire, but I want to be able to copy the music that is on my drive to my iPod (which only works on firewire). Impossible! iTunes can't even access the music on my drive.
    The drive, which I received as a gift, seems to be a bit of a cheap knock off kind. Called "Mobile Disk" and the model number is "HD-337-Combo". If anyone has had any experience with these kinds of enclosures I would be very grateful.
    Cheers!

  • Crashes with external drives (power management problem?)

    Everything worked well in Tiger on my first gen MBP. Since i switched to Leopard and now Snow, and a new UNI MBP in december 08 I have so many external drive issues.
    USB drives just disappear and power off (from the system not electrical) for no reason, mostly when connected to USB hubs. I've tried various hubs including the powered ones. But as soon as i go over two USB devices in the provided ports my problems start.. It feels like not enough juice is getting through those ports on my MBP. I never have a problem if i just connect 2 devices into the MBP, but it's not enough (i have 5x1tb external drives).
    Also the same with the express34 slot.. Everything was fine under Tiger and my old MBP, But now i get the grey wall of death so many times when connecting 2x esata 1TB drives. The system is so unstable with multiple drives both USB and. I'm currently working as a pro Photographer on assignment in Asia and these stability are starting to become a big problem.
    God forbid i'm even considering a switch back to windows for reliability, (yes, i did use the words windows and reliability in the same sentence)
    Does anybody else experience problems with multiple drives through leopard/snow leopard via Apple notebooks? I would love to hear some users experiences and hopefully find a solution to my problem.. In every other way the system works like a charm.
    I will post in 2 forums because i'm not sure if software or hardware related.
    Thanks, any help is appreciated.

    It can't be the drives because they get swapped monthly when i hand them in.. Varies brands and external boxes but always 1TB drives.. I have tried 2 different powered hubs and still experience the same problems, however those were generic ones i picked up in Asia (all made in Taiwan right? (rhetorical:))
    Ok, maybe for a last try i will purchase a branded hub and see if that helps. I still can't get the thought out of my head that it's a power problem in the MBP logic board, is it possible? I say this because the esata drives behave in a similar fashion via the expresscard.

  • Seagate Backup Plus Slim Portable Drive Experiences

    I was wondering is Mac users general had good experience with the Seagate Backup Plus Slim Portable Drive? I was thinking about getting either the 1TB or 2TB for backup/storage.
    It also says it has pre-loaded NTFS driver for the Mac. And the drive can be read by both PC and Mac. How does that work? And does anyone know if it is formatted for Mac OS Extended (Journaled)?
    Also, what does journaling actual do. I read a few conflicting threads, it either actively defrags to increase speed and prevent data corruption especially in the case of a power outage or it significantly slows down the disk.

    That drive is bus-powered, meaning it can get power only from the computer's USB ports. Unless you need small size so you can pack the drive around with you while traveling, consider instead a self-powered drive. If traveling with the drive is not an issue, also consider a larger desktop-type drive that holds a 3.5-inch form factor drive. The larger drives are historically more durable than the 2.5-inch laptop drives as would be installed in the Seagate you linked.
    There are a fair number of reports in these forums of bus-powered drives working for a time and then not being recognized. With age, electric motors can demand more power than when new and, if that demand exceeds what a USB port can provide, the drive stops working.
    IF you MUST use a laptop-class mobile external on a desktop computer, at minimum consider adding a self-powered USB hub to the purchase. It will overcome any lack of power issues the drive experiences:
    NewerTech 7 Port Hi-Speed USB 2.0 Hub with Power Adapter for Mac & PC
    OWC makes a mobile, bus-powered drive that can also use an optional power brick--best of both worlds. I have one and like its having a FireWire interface. However, you have a choice of interfaces:

  • Working photographer needs help with hard drives and raid O decisions

    Hi new here and also new to Mac well almost new been 20 years since i had a mac. i have a Mac Pro Book and this led to ordering the MacPro since I am a working photographer i made a complete switch in platforms so i have some questions and such but I did place a order on Friday for a 2.66 4gbs of Ram , 2 500 gb hard drive and a 30 in monitor and of course the ATI 1900 XT card so yes i am waiting like many for that card.
    I put initial 4gb of ram since running CS2 will at least take a max of 3gb's in the memory cache . i plan on getting 2gbs more from OWC since that seems to be the only 3rd party ram at the moment that is working correctly from reading some of the threads here. Having 6gbs is a no brainer really given the amount of Raw processing that i do along with PS work plus having e-mail and other apps open at the same time. The ram to me is the easy part although expensive . My biggest issue is what to do with the 2 hard drive slots and Raid O or not but I will start a thread on that. But i will have 6gbs total for now and the bottom line is you can never have enough ram still holds true.
    Now on to my diliemma with hard drives. I did have a raid O scsi 10k rapture and and 10 k scratch on my Dell box and I am just not sure what to do here. i ordered the 2 500 gb hard drive and I may just put them on the storage side of things than get 2 WD 150gb 10 k Sata drives. Now i could Raid O them for 300 gb and get a performace boast that way or i could keep them seperate and put everything on 1 150 drive and ue the second for scratch only. What i don't know is what Mac perfers and what works better. Not worried so much about failure of drives, thats just life in the big city stuff and you just have backups. What i more worried about is performance versus a waste . seems to me that Raid O may not even be needed with these new Intel boxes with all the horsepower going on. Now the other think I notice is the WD 150gb 10 k drives are 1.5 and not 3.0 so is it really faster than the 7200 3.0 single hard drives. I read barefeats shoot out and it seems just getting the right drives in 7200 and Raid O them maybe the answer.
    Okay i am not the biggest geek on the planet but I do know my stuff but this is a area that i look for more knowledge on this. So if i can get some sound advice in this area. i know there are many photographers out there like me pushing hundreds of images that could use the same advice. Now let's leave the money end out , folks sometimes think more with there wallet than what works best not that I am opposed to saving money but after spending over 7 k already on this system it becomes a moot point. LOL

    Ok your question is if you should RAID O the two 150GB Raptors or not.
    I think it was wise for you to get a couple of them for a boot drive with "Time Machine" coming in the next version of Mac OS X. The second drive would make a excellent bootable backup and eliminating downtime if a boot drive dies on you one morning.
    In fact any boot drive cloning software that is Mac Intel ready now would do you good.
    Now Barefeats has run some tests, and I can pretty much back up what they say from my own experience.
    Mac OS X and apps can be helped only so much by a faster boot drive, and a single 10,000 RPM Raptor is enough, RAID O a pair is overkill.
    If you install everything on the boot Raptor and keep your space hogging files (except iTunes) in new folders on another drive, even a 7,200 RPM 500GB, the two drives combined is faster as there is nearly no wait. Both drives can be accessed at the same time. Keeping the boot drive slim keeps the stylus (arm) moving as little as possible to get all the small reads/writes Mac OS X needs.
    I RAID O-ed my boot drives because 74GB was the largest they had at the time, so combining them gave me speed and larger storage. I hardly use the speed, it only comes in handy if by rare chance I duplicate a 20GB folder, then I can do it in half the time of a 7,200 RPM drive.
    Some of the drawbacks of a RAID O set, especially as a boot drive is that I have to auto-clone the whole set to a external drive regularly (I actually do a couple). Since the data path is separated with a RAID O, any drive failure results in total data loss.
    So if you RAID O those 150GB Raptors, your going to have to clone 300GB to a external drive (or another internal) regularly, like once a week. This will take considerable time and you can't use the machine while the cloning process is going on. Sure auto-cloning software like DeJaVu can be used at night/weekends, but why bother cloning more than you have to for no big speed increase?
    However if your messing with huge Photoshop files that spill over your CS2 3GB RAM limit (you need to have a "scratch" thats as fast as RAM), duplicating large files and other heavy duty drive work, then a boot RAID O will come in handy. Just remember your initial performance of 185 MB p/s will drop about 20-25% when those drives are 3/4 filled. Still 140 MB p/s is extremely good and a no worry situation.
    What is worrysome is anything below 80MB p/s (I'm talking uncached 4K write speeds under X-Bench) with a new boot drive and then as time elaspes that boot drive gets filled up and loses half or more of it's inital speed. 30 MB p/s is really slow. Beachball H&LL.

    Do Erase W/Zero in Disk Utility all new drives before laying data on them. Drives get subjected to shock which causes bad sectors on the drive. Driver software uses your data as a guinea pig to test the sectors (which you might not be able to recover the file). Zeroing does this without your data, rewriting the bad sector map so your writes are much improved, OS is more stable. etc.

  • I need Crystal Reports XI R2 RDC merge modules with JDBC driver.

    I successfully connected to MySQL server from CR XI R2 designer with JDBC driver. My application is developed in Delphi, using Crystal Reports VCL.  I need to build a Installer including executable files, *.rpt files and CR RDC merge modules in Macrovision Installshield 12.  But RDC_reportengine is not containing JDBC driver. How I to include and configure the JDBC driver?

    I just done these steps.  But following error occurs:
    Error: 772 error in file C:\...\myreportfile.rpt:

    I used mysql-connecter-java-5.1.7-bin.jar from mysql.com.
    In designer connection url is
    jdbc:mysql://mysqlserver/database
    database classname is
    com.mysql.jdbc.Driver
    My Calling the report code from Delphi is:
    CrystalReport.Connect.ServerName := servername;

  • Installing iDVD with external drive

    Has anyone had success installing iLife '05 while using only an external DVD burner. Can't get iDVD to recognize the drive and install.

    Not sure about your question, but let me relate my experience. I have an iMac G5 with combo drive. Use a Lite-On external DVD burner. the iMac recognizes this USB drive with no problems. iMovie and iDVD both work with this external drive.
    If you are trying to install the iLife program, my question is why are you using an external drive? But in my experience I have installed software from the external DVD drive.
