Error connecting to Data base.

Hi,
I am working on HTTP-JDBC scenario. Iam getting an error while connecting to Database.
Iam using Oracle DB.
I tried using the Url "oracle.jdbc.OracleDriver" and "oracle.jdbc.driver.OracleDriver" but the result is same.
The error in the JDBC adapter is as follows:-
Error during database connection to the database URL 'jdbc:oracle:thin:@<IPADDRESS>:MCQ' using the JDBC driver 'oracle.jdbc.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:oracle:thin:@<IPADDRESS>:MCQ': SQLException: Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=153093376)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))'
Could some one help me on this?
Regards
Praveen

HI,
Check the DB is ruuning or not and Listner is running or not ,
or
increase the number of retries" in the JDBC adapter configuration.
See the below links

Error to Access Data Base on SAP Netweaver 6.40 Sneak Preview SP14

Hi guys,
If someone could help me I'd be very grateful!
I've installed the NW 6.40 Sneak preview SP 19 and it's working well, however I tried to access the Data Base by MaxDB. So I provided the configuration data, such as:
Server: myServer like 192.168.0.12
DataBase: J2E
User: SAPJ2EDB
Password: myPassword
but when I try to connect on it, the system does not allow and display me the following message:
24950 user authorization failed,
I tryed to use the user Custom but it also didn't work! the system display me the following message:
Invalid Session ID!
PS: When I try to access my ConfigTool to change the SAPJ2EDB password the ConfigTool doesn't open and display me this message:
Error occurred while working with Configuration (Scanning).
Msg: Error while connecting to DB.
In my opinion I suppose that I need to apply some note. What do u think about that? I suppose it coz I've installed the WAS and I didn't do anything more!
beforehand, thanks for help!
Cheers!

Connect to data base

I want to connect to database Using JDBC with out using Top link so on.
i want to get the data thru java bean and show or valid the data in JSF or ADF Faces.
How can i do above sample program, Any pointer please help me out.

You can create a simple Java class that does the database access with JDBC and exposes methods that return and set values.
Then you right click this class and choose "Create Data Control".
Then you can drag and drop this into a JSF page.

2) The operating-system variable pointing to the instance is improperly defined.

UIComponent uIComponent, Object object) throws ValidatorException {

if(object == null || object.equals(""))
FacesMessage fm1;
fm1 = new FacesMessage("eghghgh");
throw new ValidatorException(fm1);
String phone = object.toString();
String numToken="[\\p{Digit}&&[123456789]]+";

//System.out.println("you enter a VALID number format");
/*if (phone.length() < 9) {
FacesMessage fm =
new FacesMessage("phonevalidator number should be at least 9 digits");

But my question is i dont want write this error message here(Can accept only numbers) .i have one table in database .this error message and error no are there .how i will populate from database?

Hi,
Always mention your JDev version and the technologies used.
Have you tried creating a VO based (assuming you are using BC) on the error messages table, get the message according to the number (you can have a method in that VO impl, that would take the error number and return text), and display it?

Error opening data base for the library for Aperture

Hello,
I have been using Aperture all day and for some reason am now getting this error message when trying to open it again.
Te was an error opening the data base for the library "users/*******/pictures/aperture3triallibrary.aplibrary
Has this happened for anyone else?
Many Thanks

When I hold down ⌘⌥ firmly, at the same time, and with these keys held down double click the Aperture library that I want to repair, I get this panel:
Then, when I select "Repair" Aperture will show a progress bar and the Dock icon will stay highlighted.
When it is finished, the Aperture window will open.
When I select repair, it seems as though it doesn't run. I don't get a dialog box to confirm it's happening and on the dock the little light under the Aperture icon isn't lit, which seems it is'nt open or running.
After you select "Repair", does the panel close and then nothing? Or does the panel not react?
I still don't see fully, what is going on on your mac.
But it is a good sign, that you can create a new library. That suggests, that Aperture is running correctly on your mac, and "only" your old library has a problem. Try to test the new library - import a few images and try to adjust them.
Once you are convinced, that the new library is working well, you have three options.
Try "Rebuild" instead of "Repair".
Or try to import your old library into the new library (Aperture's main menu bar > File >Import > Library) - that is another approach to rebuilsd the library.
Or restore from backup. To restore from Time Machine, open a Finder Window showing your Aperture library, and then enter Time Machine. Go back in time to the most recent date that has a working Aperture library and select "Restore". If you have enough space on your disk, restore to a different folder and don't overwrite your current library.

Léonie
