I would like some help to run sql queries in Ubuntu. For a school IT project, we must write a Java program that runs queries. Seeing that I'm going away on holiday and will be away from my Win7 desktop, I will have to work on my Ubuntu laptop. When I run my program, I get these two sql exceptions:
Code:
sun.jdbc.odbc.JdbcOdbcDriver
No suitable driver found for jdbc:odbc:ITPAT2010
Note: it is not my program that is causing the problem, since it works fine on Win7. But here's my code anyway:
Code:
void OpenDB()
{
System.out.println("INTO BRIDGE");
String url = "jdbc:odbc:ITPAT2010"; //JOU BRUG SE NAAM
[code]....
I believe the drivers that handles the connection to the database aren't installed. The format of my database is: *.accdb (was created on Win7 using Office 2010). I can't open this file, probably because I have no database programs installed?

I have this problem that whenever java is running (eg. Runescape), sound works only in the Java window, and I don't get sound from flash, mp3s or anywhere else.I found several similar threads but most of them were unsolved, and the few solutions didn't work.Note: Earlier, I used to use IcedTea browser plugin for java, which didn't seem to give any sound problems, though was a bit glitchy otherwise. This problem started only after switching to the Java plugin found

I'm having some trouble with Java based games. I am running 11.04 64x and I downloaded and installed the latest sun-jvm. I know my hardware can run these two games very well (Minecraft and Spiral Knights). I'm wondering if maybe sun isn't my default plugin.
View 5 Replies View RelatedThe main problem is that the software was developed about 15 years ago and is incompatible with the most current version of Java. I would like to know how to install an older version of Java so that I can use it with just this one application, without changing the version of Java that I use for everything else.

View 9 Replies View RelatedI'm trying to get a Tomcat server running using the Java VM -server option on Ubuntu Karmic 9.10 (I'm using the official Karmic AMI on EC2: ami-bb709dd2)
I install Tomcat:
Code:
sudo apt-get -y install tomcat6
I set up a bit of configuration in /etc/default/tomcat6:
Code:
JAVA_OPTS="-Djava.awt.headless=true -Xms1024m -Xmx1024m -XX:PermSize=384m -XX:MaxPermSize=384m"
I can start Tomcat with no problems:
Code:
sudo /etc/init.d/tomcat6 restart
However, if I add the -server option into the JAVA_OPTS variable, like so:
Code:
JAVA_OPTS="-server -Djava.awt.headless=true -Xms1024m -Xmx1024m -XX:PermSize=384m -XX:MaxPermSize=384m"
I get this:
Code:
$ sudo /etc/init.d/tomcat6 restart
* Stopping Tomcat servlet engine tomcat6
...done.
* Starting Tomcat servlet engine tomcat6
Invalid option -server
Cannot parse command line arguments
How do I set the -server option correctly?
All day today, my laptop has been absurdly hot.The core temperatures were exceeding 70.0C even though it was on a cooling pad and I had disabled wireless, lowered the screen brightness, and put the CPU on Powersave. (For comparison, the temp usually stays at 45.0C if I do all this)
Finally, I decided to check htop, and I found IcedTea Plugin at the top with 99% CPU usage. This is used to run embedded Java applets (Java, not Javascript). Curiously, no Java applets were running at that time.Now skip ahead an hour to when I finally discover that the IcedTea Plugin was left over from earlier because it didn't stop running when it was supposed to. Looking online, I see several complaints about Java being very taxing on the CPU in Ubuntu, but I don't see anything about Java applets continuing to run after they're gone.
Can anyone who has Java installed confirm that this happens on their system?
1. Open htop. Search for "icedtea" to make sure it isn't already running. Then click on "CPU%" to sort the list.
2. Open this page in Firefox: www.java.com/en/download/help/testvm.xml
3. Check htop. Is IcedTea climbing to the top? (if you have Java, it likely will, because this is a common issue)
4. Navigate off of the Java.com page by closing the tab or clicking Back.
5. Here's what I want to know. Check htop again. Is IcedTea still there?
6. Restart Firefox to get rid of IcedTea.

My sound is otherwise working fine, but for some reason i'm not getting any sound when running java applets. This issue is very important to me, i would -really- like to get the sound back on this applet.it's a java runtime environment applet, running in embedded in firefox. Somehow, the systems isn't detecting it as a application outputting sound.
i tried uninstalling the sound manager application via synaptic, selected the 'completely remove' option, and wound up uninstalling essentially the entire OS last weekend. i'd like to not repeat that mishap, as i lost all my data.

View 5 Replies View RelatedKernel version: 2.6.26-2-686
Java version: 1.6.0_0
I'm going to run a full system update, but I doubt that'll work.
What happens is I turn the computer on, log in, start the application with:
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
and it will work fine for a while, but then, while we're playing, it'll become unresponsive and crash. I then go over to the physical computer, wake the monitor up by pressing the down arrow, delete the "[[B" that appears, and try to issue the applications stop command to save and close the application. This doesn't work. The computer registers what I type and registers the return, but nothing happens. I switch over to my second console, log in, find the PID of java, and attempt to kill the java process as root. It accepts the command and gives me another line of prompt, but when I switch back to the first console, nothing has happened.
I then switch back and try to issue a shutdown for right now, and it'll get to "Sending processes the SIGTERM signal", and then it waits for them to be killed, but will not progress further than that. I then have to either force the shutdown with the 3-second hold for the power button, or I have to turn off the power bar it's attached to.
Also, if I'm at the prompt and press backspace, which gives me a system beep, it doesn't stop. Instead of one, short beep, I get a never-ending tone, as opposed to the beep.
The computer does run a little hot; It's in a closet and it's kind of crammed, but it's never so hot that you can't handle the computer.

I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.
However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.
I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.
regarding user permissions:
I have user A who owns a .jar file
I have user B. who needs to run the .jar file
I have Java which is owned by root.
I would like to work out whether/how user B can run the .jar file, in Java, with the permissions of user A. As I understand it, a running process in Linux typically takes the permissions of the user who executes it. However, the way I'd like to configure user B, the permissions I want them to have wouldn't be sufficient for the process to successfully run.I know you can also set a process to take the permissions of the owner of that process, but in this case the actual... executing process would be Java, which runs the .jar file, and I def. don't need this, let alone every single instance of Java on my server, to execute with root priviledges. So like I said, basically I am trying to work out how to let user B run this specific process with the process elevated to this set of priviledges which user B otherwise does not have.
I recently started running a Minecraft server for myself and some friends and am running it via Linux. I'd like to set things up so that a friend of mine can, as needed, telnet into the server and restart Minecraft as needed, as well as a couple of other things, without giving this friend the same access rights I've given myself to the same files. The minecraft server process runs in a screen, and I've worked out where screen can be set up so multiple users can get into it. However, if I'm running minecraft under my own user name, then that seems like it will just end up letting my friend, from his account, screen into my own account. SO the brilliant idea I had was, what if I had one user account which only existed to run the server, which both me and my friend could screen into as needed, which wouldn't have any more rights to anything than my friend has with the exception of being able to execute this one .jar in Java.
