Class oracle.disco.DiscoApplet not found ?????

Hi,
I'm unable to open disco plus 10.1.2.2 today and it was working fine for me till yesterday.
what i getting in console i pasted below.
Any suggestions ????

Hi,
This looks more to me like it was an applet conflict with the newer 10.1.2.2 jar files and the older applet that was cached.
I say this because I have used the 1.6 plugin without issue (not that it is officially certified :-) ) with versions 10.1.2.0.2 and 10.1.2.2 and I have seen that conflict before when applying patches that udpate the Discoverer Plus applet jar files.
If you have this occur again, try to clear your JRE cache (start >> control panel >> java) and then reconnect, it will force the download of the new udpated applet. Likely why it started working when you deninstalled and reinstalled. Not sure if that would be considered a Discoverer bug/issue or a JRE issue when a new applet doesn't overwrite the old one.
Hope that helps,
Steve.

Hello,
from the little information in your post i would say try to import oracle.sql.*, oracle.jdbc.* and oracle.xdb.*. Make sure your project can access the following libraries ojdbc14.jar and xdb.jar.

Hi,

Can anyone tell me what is wrong here. i have a funny feeling that the classpath is not set properly. let me know whats wrong here.
ps: i havent set the system DSN - coz i am getting stuck at the drivers itself.

Oracle service orcl not found in windows services

hello
i'm facing a very serious problem. MY server ORacleserviceorcl not found in services. all services currently up and running. but ORCL service not show there and my database is down how i start my database. i found this problem first time. plz help me how to Start oracle. my ORacle version 10g on windows server 2003

Niall,
Do you think that the OP should try the following command to re-create the service:
C:\> ORADIM -NEW -SID ORCLAs far as I have been able to determine, that command will not cause an issue, and will return an error if the service already exists.
To the OP: It is possible that a utility, such as HiJackThis, was used to remove the service, the Windows registry is corrupt, someone used ORADIM to delete the service, someone was hacking away in the registry and accidentally removed the entry for the service, or any number of other possibilities (I am not sure if MSCONFIG will remove a service when that program disables the service, but that might be another possibility, and dropping the database is another possibility).

Added the note about dropping the database as a possible cause - see if the datafiles still exist.

BO4 - auit universe changing to oracle connection - table not found

Hi,
We have found the BO4 sample audit universe on sdn and can open in IDT but when parse the objects says table not found.
The tables physically exist on database and when do insert in data foundation layer they are there.
Changed connection from mysql to our boaudit databse connection.
Any ideas?
Thanks

Hi Philip,
I suppose you have downloaded this link:
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/40711187-04e8-2d10-d190-851e20c7665a
This contains only the Activity universes for Sybase and SQL Server but not Oracle. Unfortunately, every database requires its own Activity universe. I am afraid that you have to build your own.

Julian

Error: Class java.util.ArrayList not found in import

Bear with me, I'm learning. That's part of the problem.
I'm trying to teach myself JSP using a book based on Tomcat, but running it on an Oracle 9iAS server that I don't control. (The DBAs do that.) I'm running into constant problems compiling and using classes and such, I think because of the different directory structures on the two servers. (See subject error.)
So, what I'd like to know is: how do I set up a default/main/whatever-you-want-to-call-it directory under which I can store my practice applications, such that 9iAS will function correctly? We're not using OC4J as far as I can see (no such directory, though there is a J2EE_containers folder), just JServ. Or, conversely, can someone explain in simple terms the basic 9iAS directory structures for deploying apps on 9iAS? I've been 'round and 'round the Oracle documentation until my head spins, and can't find this basic information.
Help, please!!

You will have to make Kawa to use the correct jdk
Look into
Options-> Directory
Make a new Profile if it point to your old jdk version

Oracle.DataAccess.Client not found[SOLVED]

Hello,
I am trying to run a stored procedure using C# and I need to use the Oracle.DataAccess.Client but when i enter
"using Oracle.DataAccess.Client;" visual studio throws the error:
Error 1 The type or namespace name 'Oracle' could not be found (are you missing a using directive or an assembly reference?) P:\data\ActionItemLog\ActionItemLog\updateComment.aspx.cs 14 7 ActionItemLog
And I installed the newest ODTwithODP for .NET. I would really like some help on this subject and I will do my best to clarify even more if needed.
Thanks in advance,

Just a stupid mistake on my part all I had to do is in visual studio add the Oracle.DataAccess.dll file to references. I hope this mistake saves some one a bit of time in the future.

Oracle Portal Homepage Not Found.

Hi,
I've installed Oracle 9i Portal on Windows2000. Login server

error (as found in install.log):

Pl. reply.
Thanx in advance,

8.1.7 installs scott using System for the default and temporary
tablespace. This can sometimes cause problems. To avoid problems,
do the following for scott user:
a) As system, issue the following commands:
ALTER USER scott
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp;
b) Log in as scott and move all of scott's objects to the
users tablespace.
For example:
ALTER TABLE tablename
MOVE TABLESPACE users;
I hope this will help.
