Unable to load/parse portlets config SAX2 driver

Hi All
I try no test our software with several AS (Resin, HPAS, etc.) With OC4J we have $subj error. This is my steps:
1 Unzip oc4j_extended.zip
2 Add web-module to default application.
in application.xml:
<web-module id="Axiom" path="/opt/gorod/axiom" />
in http-web-site.xml:
<web-app application="default" name="Axiom" root="/axiom" />
3 Start it
4 Try to connect http://mysite.com:8888/axiom
And watch my log:

Why? File xerces.jar Placed with application (in /opt/gorod/axiom/WEB-INF/lib) and have all permissions.
Also I try to start java with -Xbootclasspath/a: option but it has equal result.
PS Sorry for my english :-\

mv xerces.jar $J2EE_HOME
cd $J2EE_HOME
java -Xbootclasspath/a:xerces.jar\;jaxp.jar -jar oc4j.jar &
No changes :-(
But with
java -Xbootclasspath/a:xerces.jar:jaxp.jar -jar oc4j.jar &
VM not starts and shows error:

Torrentflux 2.4 (ADONewConnection: Unable to load database driver)

I'm trying to setup Torrentflux 2.4 on my server.
I used the torrentflux PKGBUILD vom AUR: http://aur.archlinux.org/packages.php?ID=1664
I set up Apache/MySQL/PHP following the guide. PHP test script is working fine:
<?php phpinfo(); ?>
I setup a symbolic link from /srv/http to my /opt/torrentflux
ls /srv/http/
insgesamt 4
-r--r--r-- 1 root root 20 6. Mär 21:23 test.php
lrwxrwxrwx 1 root root 17 6. Mär 21:07 torrentflux -> /opt/torrentflux/
When I try to open /torrentflux/login.php in my webbrowser it says
ADONewConnection: Unable to load database driver ''
I left the default in torrentflux' config.php:
$cfg["db_type"] = "mysql"; // mysql, postgres7, postgres8 view adodb/drivers/
ls /opt/torrentflux/adodb/drivers/
insgesamt 532

I'm pretty new to the whole LAMP stuff, so can please any1 tell me what's going wrong?

Ok, some questions:
1. Did you enable mysql in php.ini?
http://wiki.archlinux.org/index.php/LAMP#MySQL
2. Did you read / follow the torrentflux installation guide included with the installation?
(if not, check here: http://www.torrentflux.com/)
3. I have not worked with the package from AUR, the package form the official site (again, http://www.torrentflux.com/) works well for me. Did you try this?

is the driver name correct?

I usually have another string, but I might use a different mysql driver. Try opening your mysql driver with winzip and see if the class is there and at the defined directory place

I have seen this error when I'm executing inside one of the (j2ee sun reference implementation) server containers (either web or ejb). I believe its caused by "something" having previously loaded the "sax 1 driver class". In my case, I think the container or server is loading the sax parser from a jar that contains a sax 1 version. If you can, ensure that nothing is loading the sax 1 parser from another jar on your system. Verify that you are loading the sax parser from a jar containing the latest version so that you get the sax 2 compliant parser. Good luck!

Unable to load mySql Driver in Java class invoked using bpelx:exec

Hi ,
I am trying to connect to mysql database in my java class.when i run this class in Jdeveloper it loads the driver without any problem.I can chk the log in the Jdev messages area.Now I am invoking this class from the BPEL process through <bpelx activity.But when i run my BPEL process it throws runtime exception "classNotFoundException:unable to load com.mysql.jdbc.Driver".I have set the project properties ->libraries to the class path of the mysql jar file as well.
Now if i try to connect with the Oracle driver then it is working fine.
I know this is a classpath issue.Can anyone tell me if there are some other settings to make it work fine.
the java code :
System.out.println("in getConnection method");
Class.forName("com.mysql.jdbc.Driver").newInstance();
System.out.println("loaded Driver :");
String url="jdbc:mysql://ntlv014:3306/wx";
_jdbcConnection = DriverManager.getConnection(url,"development","ber1nger");
System.out.println("Got Connection :"+_jdbcConnection.isClosed());

I think you have 2 options..
either put the jar for the mysql in the classpath on the server...or try something like this :
http://forum.java.sun.com/thread.jspa?forumID=17&threadID=633158
try to put the jar of the mysql into the suitecase of the bpel.
never seen this coming around...so..it's just a wild guess.

Unable to load Driver Class

Hi There:
When I try to connect to the Oracle 8i via this applet , I get the following run time error.
Any help will be appreciated.
I am using j2sdkee1.3.1, jdk1.3.1_02 and Oracle8.
I also need your suggestion please. I have inserted some BLOB data in the Oracle table. I will need to display the BLOB data to the end users. I plan to convert this BLOB data into string format so that my applet can display the same. Further the string will have to be edited by the end users. I will then convert this modified string back to byte array so that I can insert the same as BLOB.
Please let me know applet or the servlet? Which is better option.
Users are reluctant to use any kind of WebServer because it will introduce the additional layer of complexity.
Any help will be greatly appreciated.
Thanks in advance.

Hi,
maybe I'm too late but try the following :
It seems that Your IDE doesn't check the path to Your classesxxx.zip file.
Or Your classesxxx.zip file is corrupt.
We had this error after downloading the classes12.zip for Oracle versions

Unable to Load USB Driver in LV for Total Phase's Aardvark I2C adaptor

I have tried to instal Total Phase's Aardvark I2C USB driver for LabVIEW on two computers and two versions of LV (8.5 and 7.1) without success. The Windows driver seems to be working fine as their command center gui terminal-esque program works without a hitch, but the LV DLL doesn't seem to work.
Attached is the very simple vi to find connected Aardvark USB devices (aa_find_devices). It always returns the same error code, 8002, which resolves to:
AA_UNABLE_TO_LOAD_DRIVER
-2
unable to load USB driver
From their documentation: http://www.totalphase.com/docs/aardvark_datasheet/sect005/#s5.9
This looks like perhaps the LabVIEW DL, "aardvark.dll" maybe having a versioning issue. So my question is this: Using LabVIEW, how does one debug dll dependencies and resolve issues like this? Do I need the source code for the lib?
Cheers,
Joe Gorse

Dear Joe,
Let me start off by apologizing for the inconvenience you
have gone through. I am an engineer at Total Phase. We are
working on fixing this issue for our next release of the
Aardvark LabVIEW Driver. This forum post was only brought
to our attention today. In the future, you can also let
Total Phase know about these kinds of issues by emailing
[email protected] We are very responsive through
email or phone.
The problem you are experiencing has to do with versioning
issues between our DLL and USB driver. Specifically, DLLs
before v5.xx must use the older version of our USB driver.
By replacing the DLL from our latest version of Control
Center, you have effectively upgraded the DLL that the
LabVIEW driver is using and made it compatible with v2.xx of
the USB driver.
The most likely reason that smercurio_fc did not see a
difference between the DLL in Aardvark Control Center and
the LabVIEW driver is because he is using an older version
of Control Center and correspondingly an older version of
the USB driver.
The reason that we have not packaged the LabVIEW driver with
latest DLL is due to the fact that a few functions have
changed their function prototypes (for example aa_open_ext
and aa_spi_write), and the VIs have not yet been updated
accordingly. Although updating the DLL solved your USB
driver issue, it introduced this new issue. If you try to
use these certain VIs, LabVIEW will error out.
We are currently working on updating the LabVIEW drivers to
work cohesively with the new DLL and USB driver, and this
should be available soon. If you need immediate
availability to the functions with new prototypes you will
have to change it manually. The other recommended option is
to simply revert back to the DLL that is packaged with our
LabVIEW driver and downgrade the USB driver back to v1.xx.
I will make sure to post again once the update is released,
and I once again apologize for the inconvenience.
Best regards,
Etai

Unable to load HP printer driver-Error message!

Hi,
Just wondering if anyone can be of any assistance.
I recently purchased a HP Photosmart 2575 all-in-one printer and installed the necessary software, which said it was successfully installed. However, whenever I boot up the G3 I keep getting the following message 'Unable to load the printer drive, open the applications Get Info dialog and increase the preferred memory size. If this does not help try quitting all other applications or reinstalling the printer software.'
After clicking ok on this message about four times the message goes and I am able to print fine. Just wondering why this is happening. I have increased the memory allocation and also turnt on the virtual memory to see if this makes any difference, but all to no avail. I have also uninstalled and then reinstalled the software to see if this makes a difference, but that didn't help either.
Any help would be greatly appreciated.
Thanks in advance
PS: The printer is connected via ethernet on my router to enable me to print from another machine

Use Techtool Lite or Trash*Desktop (TD may delete Finder comments )to rebuild your desktop w/extensions off. Does a better job than manually & you avoid all the finger gymnatics. You just have to hold down the shift key to shut off extensions.
Restart to turn the extensions back on again.
If you want to rebuild manually, see KB article http://docs.info.apple.com/article.html?artnum=10182 Rebuilding Desktop File and Icon Recovery.

Unable to load LabVIEW RT from drive

Trying to boot RT on PXI-8187 controller with original setup, what ever RT boot selection is used either hardware switch or BIOS RT boot option, the terminal will show the following:
Unable to load LabVIEW RT from drive!
Booting safe mode from ROM...
mount: Mounting /dev/Ma1 on /home/ftp/c failed: Invalid argument
Entering safe mode.
IP address is: 0.0.0.0
Of course after that you can't do any thing to configure the RT target from the MAX on the host computer.
Please Help.

Hi,
I used the recovery CD to change the file system to NTFS, it took a while and it installed windows XP from scratch differently from FirstWare that ghosts it (I think). And it didn't install any NI stuff what so ever.
At the end I got the same result as with using the remote system format disk option.
i.e. The RT controller boots in safe mode displaying the previous message without the mount error but this time I can configure the IP address.
Still I can't install software to it, I get the list of features to install, I select them and press next, then I get a dialog saying:
Cannot process install because other dependencies are required:
LabVIEW RT 1.0.1
LabVIEW RT 6.0.1
LabVIEW RT 6.1.0
LabVIEW RT 7.0.0
LabVIEW RT 7.1
Is this a host or RT Controller issue now?
What's next? Thanks for the help

Help Please .... Unable to load Driver Class

Hi There:
When I try to connect to the Oracle 8i via this applet , I get the following run time error.
Any help will be appreciated.
I am using j2sdkee1.3.1, jdk1.3.1_02 and Oracle8.
I also need your suggestion please. I have inserted some BLOB data in the Oracle table. I will need to display the BLOB data to the end users. I plan to convert this BLOB data into string format so that my applet can display the same. Further the string will have to be edited by the end users. I will then convert this modified string back to byte array so that I can insert the same as BLOB.
Please let me know applet or the servlet? Which is better option.
Users are reluctant to use any kind of WebServer because it will introduce the additional layer of complexity.

Applet, Connector/J, unable to load driver

I have written an Applet that is using the Connector/J com.mysql.jdbc.Driver to connect. When I compile and run the Applet with VisualCaf� and the AppletViewer, it is able to load the driver, access the database, exectue queries, etc. The problem occurs when I upload my files to the webspace.
My Applet loads, but when it tries to load the driver, these are the exceptions that I catch:
"Error loading class: com.mysql.jdbc.Driver
java.lang.NoClassDefFoundError
Failed to initialize driver: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver"
Here is the code having the problem:
import java.sql.*;
public DatabaseConnection()
// First, we initialize the driver.
try
//System.out.println("Initializing Driver...");
Class.forName("com.mysql.jdbc.Driver").newInstance();
//Class.forName("org.gjt.mm.mysql.Driver").newInstance();
//System.out.println("Driver initialized.");
catch (Exception e)
System.out.println("Failed to initialize driver: " + e);
On my webspace, I have included the mysql-connector-java-3.0.8-stable-bin.jar file in the same directory as my main class file. In the HTML code, I use the ARCHIVE tag and give it that .jar file. I have even un-jarred the file, retaining the original directory structure and placed those in the same directory. The .jar file seems to download when I go to the page and load the Applet.
Is there something I'm missing that lets the Applet load the Driver? The Driver i'm using is a Type 4 Driver, which should be useable by an Applet.
Any help would be very much appreciated - I've struggled with this for a long time, now.

For anyone else out there using the Connector/J driver to make an Applet connect to a mySQL database, read on.
The mysql-connector-java-3.0.8-stable-bin.jar does not work with Applets. At least, it would not work for me after trying many different things. So, I downloaded an earlier version: mysql-connector-java-2.0.14-bin.jar and everything worked fine (!!!).
I hope this helps someone else with the same problem!! If the number of forums with very similar postings that i've run across is any indication, there are a lot of people having this problem!
