Also, Oracle claims that you can use newer drivers, such as the 10g drivers, with older databases. See the Interoperability Matrix:

Help.about "java -jar"

execute "java -cp second.jar;main.jar main.Main", it is ok.
but
execut "java -jar -cp second.jar main.jar", it fails. It report that java can't find one class in second.jar. The second.jar is not any changed.

if you use the -jar arg, then java needs to know which Main-class to run in the jar. You have to state this explicitly in the file 'Manifest.mf' which should be in your jar-file in the folder 'meta-inf'. In that file state the location of the main-class like this:
Main-Class: package1.package2.MyMainClassName

Hi Hussein,
You mean reboot the solaris server and then start database and applications services. We have two databases running on this solaris server.

Pointing portal server from classes12.jar to ojdbc14.jar JDBC driver

Hi,
     Some time ago we upgraded our portal landscape from Oracle 9.2.0.7 to Oracle 10.2.0.2. Using OSS Notes 867176 and 915079, we pointed our portal servers to use the newer and recommended ojdbc14.jar driver. This included using Config manager to change the rdbms.driverLocation parameter to point to the new driver.
     A few months later (last week), thinking that we had our bases covered, we removed the old ORACLE_HOME, /oracle/<SID>/920_32. Upon restarting the portal we got quite a shock- it would NOT come up! The first problem was the bootstrap.properties in the /usr/sap/<SID>/JC00/j2ee/cluster/bootstrap directory which had the same dbms.driverLocation parameter pointed to the old driver in the old ORACLE_HOME. After correcting this, we ran into further problems with neither the dispatcher or the servers (2 per system) coming up. Find this curious, we ran the following unix commands and identified more *.properties files with the same rdbms.driverLocation parameter-
cd /usr/sap/<SID>/JC00/j2ee
find . -name '*.properties' -exec grep -H 920_32 {} \;
./deploying/rdb.properties -
            rdbms.driverLocation=/usr/sap/EPP/JC00/j2ee/classes12.jar
./cluster/server0/cfg/kernel/ConfigurationManager.properties -
            rdbms.driverLocation=/usr/sap/EPP/JC00/j2ee/classes12.jar
./cluster/server0/cfg/kernel/ConfigurationManager.properties -
            rdbms.driverLocation=/usr/sap/EPP/JC00/j2ee/classes12.jar
./cluster/dispatcher/cfg/kernel/ConfigurationManager.properties -
            rdbms.driverLocation=/usr/sap/EPP/JC00/j2ee/classes12.jar
./templateconfigurator.properties -
           $=/usr/sap/EPP/JC00/j2ee/classes12.jar
We then proceeded to manually edit each of the files to use the newer ojdbc14.jar driver. Surprisingly, it turns out that editing the ConfigurationManager properties files for the 2 servers and the dispatcher had no effect- upon recycling the portal the entire cfg/kernel directory gets wiped out and replaced.
So what's the problem here? I don't have an issue with directories being recreated- but why is the ojdbc14.jar driver setting not being picked up from the change made for each server and dispatcher in the Configuration Manager?   I have examined all the services listed in the Configuration Manager and the Visual Administrator and can find no more references to the old ORACLE_HOME.
Oh, incidently, curiously enough, for single portal systems, the JDBC driver is obtained from the /oracle/<SID>/102_64/jdbc/lib directory and not from the /usr/sap/<SID>/JC00/j2ee directory which is the case for portal servers involving more than 1 server.
Hoping for help here ...
Sincerely,
Steven McElwee, Duke University

right click ur project and select properties. In Java Build Path add the ojdbc14.jar in the librariies tab.

Classes12.jar looking for ocijdbc8.dll instead of ocijdbc9.dll?

I have installed the client portion of Oracle 9 release 2 and written an EJB that uses the oci JDBC driver. I have no other oracle installation on my machine, so I only have the ocijdbc9.dll in my %ORACLE_HOME%\bin directory, not the ocijdbc8.dll.
The classes12.jar file (installed by the same installation mentioned above) is in my classpath.
The code throws an "UnsatisfiedLinkError: no ocijdbc8 in java.library.path". This does not make sense to me because it should be trying to load ocijdbc9.dll.
Please assist.
Andreas

Hi,
Thank you for your response, but I guess I should have been a little bit more specific. As mentioned, I installed oracle 9 release 2 client only and have no other oracle installation on my machine. I am working on my laptop with Windows XP Professional. The application server hosting my EJB's is Weblogic Server version 7.0. So I am NOT using OC4J. I am accessing an Oracle Database on a Tru64 UNIX box.
My EJB cannot create the connection because classes12.jar in my ORACLE_HOME\jdbc\lib which is in my classpath tries to load ocijdbc8.dll. Since I have only installed oracle9 release 2, should it not be looking for ocijdbc9.dll??? ocijdbc9.dll exists in ORACLE_HOME\bin. The classes12.jar was installed by the oracle9 release 2 client installation.
Please help me....
Regards,
Andreas

Tomcat can't find oracle classes12.jar what to do?

hi,
i have managed to come this far with my "simple" webapplication under tomcat that i can see the application startpage but when i click browse the following
exception is thrown:
java.lang.NoClassDefFoundError: oracle/sql/NUMBER
since i have tried to put the classes12.jar in every reasonable directory without effect, i have to bother this forum. does anyone know "where the dog is burried"(german saying)?
greetz
Selim Keser

I'm sorry I wasn't clear.
I have a feeling you might not have to do this because you wouldn't have gotten so far without knowing how.
"chown" is a command in UNIX like systems to change the owner of a file or directory.
When I was having problems similar to yours, I noticed that all of the files that I copied onto my server listed the owner as root and the group as root.
The version of Tomcat I am running on Linux requires that the files be owned by "apache". So by changing to the directory where the files in question are located, you can run the UNIX command "chown apache:apache *" and it will change the owner/group to apache.
If you're running in some other OS (Windows) I can't really help since I've never successfully installed and invoked Tomcat on Windows.
HTH.
Thanks, George

9.0.1 classes12.jar

The Readme page for the 9.0.1 drivers mentions classes12.jar, but the file doesn't appear to be available for download.
Anybody know if/when/how the jar versions might be available?
Thanks
null

The main thing I'm looking for is the jar formatted archive, not the zip. I know that the classes are identical, and I know I can create a jar file from the zip. But since the readme mentions that the jar is available I'm wondering how to actually get it. Here's a copy of the link from the download page:
http://download.oracle.com/otn/utilities_drivers/jdbc/901/classes12.zip
BTW, I tried changing "zip" to "jar". No luck.
Thanks for trying to be helpful.

Need help in compiling jar file

I have download the a jar file from http://www.geocities.com/itextpdf/.
The problem is I do not know which file should i compile first.
Anyone can help me detecting which file to compile first or a command for javac to compile the whole java file contains in the *.jar file?
Please help me..
Desperate to run the class file.
Thank you

Really Sorry to disturb you again..
It has 100's of "****" cannot resolve symbol.
u might have 100,s of it but only few classes will have dependencies
try out different combination still if it has so many errors
than
little bit of intelligence is needed
1)sort out the classes in different packages which are having high dependencies
2) find out the class which has most dependices
3) try all the ways to compile it first (comment the lines which has the reference to the uncompile class.
4) than compile the other class
i heard about the jar files having only class files
when we make a jar file which are having the class files of our source we intrelligently write a script file to select the order to compile the source files
try to find is there any jar ( containing the class files) available in the same site
hope this will help

HELP about analog output video

Hello, I´m need help about analog output video in Premiere CS5 using Matrox RTX2. I need to crop a video with resolution in 1440x1080 to 4:3 in output analog. But what happens is wrong (I think). My video is in format anamorphic and the other option is 16:9 letterbox. Is there any way to crop the video without using effects. Thanks a Lot and sorry my bad english (my native language is Portuguese).

There are no 4:3 HD specifications. You'll have to put the video into a normal SD sequence, and scale it down till the top and bottom of the video meet the frame. That way the sides will be cut off.

I installed teh update a few days ago but when I open Firefox it says :"You're not on the lastest version . . ", but at "Help" & "About Firefox" it shows 9.0.1 "latest release". There's a glitch somewhere.

This is the message when I Open Firefox:
"You're not on the latest version of Firefox. Upgrade today to get the best of the Web!"
At <Help> & <About Firefox>, it shows
Firefox
9.0.1
"Firefox is up to date"
"You are currently on the release update Channel"
One of those messages must be wrong. Either way Firefox seems to work fine otherwise. Thanks and regards, Peter Spielman

Is your homepage set to www.google.com/firefox? If so, that page is wrong. You should change your home page to about:home or some other site instead. The google.com/firefox page is no longer supported.

I have three user accounts on one computer. On only one account when I when I check Help - About fire fox only one user account says apply update and won't apply. The other two work fine.

One of three user accounts on the same computer appears to not be updating to 8.0.1 correctly. One admin and one none admin user account says it is up-to-date. The other non-admin user account, under Help About Firefox says apply update, but won't.

As long as you installed MS Office into its default location (the top level /Applications folder) it will be available to all user accounts on the Mac.
As far as licensing is concerned you only have to enter the license code once, which you should do right after installing MS Office, in the same admin account you installed it from, by opening any one of the MS Office applications. There is no additional licensing required for additional user accounts on the same Mac.
Each user account is able to run the Office apps. The only thing you will have to do is go through an initial setup screen in each user account (but this setup does NOT involve entering any additional license codes).
You may have problems if you installed MS Office in a particular user account (i.e. NOT in the top level /Applications folder).
