Can any body identify my problem with database connection?

My connection statement looks like this
Class.forName(sun.jdbc.odbc.JdbcOdbcDriver);
DriverManager.getConnection("jdbc:odbc:ram");
Iam using jdk1.3 and oracle 9i client edition.
The exception is .......
java.sql.sqlexception: No suitable driver.
The interesting thing is, with the same above connection statement , i am able to connect my core java program with oracle. But not with J2ee application.
Can anybody resolve my prob?

This is the thread where Guhan asked the same question:
http://forum.java.sun.com/thread.jspa?threadID=5209455&tstart=50
He's a classmate of the OP.
If anyone thinks they can improve on this mess, please be my guest.

Problem with database connectivity

Hi guys,
I'm having a problem with database connectivity . I'm using the mySQL database & org.gjt.mm.mysql driver.
I've kept the org folder under the directory where the Database.java program is residing .
My program is as follows:
import java.sql.*;
public class Database
     Connection con;
     public void connect()
          System.out.println("In connect.");
     public Connection connectDB(String username,String password,String database)
          try
               Class.forName("org.gjt.mm.mysql.jdbc.Driver");
               String url="jdbc:mysql:"+database;
               con=DriverManager.getConnection(url,username,password);
          catch(SQLException e)
               System.out.println("SQL Exception caught:"+e);
          catch(Exception e)
               System.out.println("Exception e caught:"+e);
          return con;
     public static void main(String args[])
          try
          Connection c;
          Database db=new Database();
          c=db.connectDB("root","","//192.168.0.2/squid");
          System.out.println("Connection created.");
          c.close();
          catch(Exception e)
               System.out.println("Exception caught:"+e);
It gets compiled but gives the following error when run.
Exception e caught:java.lang.ClassNotFoundException: org.gjt.mm.mysql.jdbc.Driver
Connection created.
Exception caught:java.lang.NullPointerException
I don't know why the class is not found.Pl . help me rectify my mistake.Is there any other path to be set?
Thanks.

You need to run it with the JDBC driver in the classpath
java -classpath .;[mySqlJdbcDriver.jar] Database

Problem with Database Connections in the designer - Catalog not updated

This is Crystal Reports 2008 (12.2.0290). We have a number of reports that are viewed using the .Net runtime with the connection details set at runtime using ODBC to talk to SQL Server on different systems. This all works fine and is not the problem. The problem is when editing reports in the designer take the following example:
Developer 1 creates report on their machine that references tables. DSN Name is DEV_DSN, pointing at their local database on their machine called DEV_DB1. Developer 2 needs to edit the report on their machine with a DSN of the same name (DEV_DSN) but this points to a different database on developer 2's machine called DEV_DB2.
Developer 2 goes to the Set Datasource Location option in the Database menu to get it to point at their local DB only it doesn't work. They click on the first table included (or the connection name) in the report and click update - they are prompted for the logon details for their local DSN/DB and supply them but they see an error indicating that there is an "Invalid object name" because the table is still being prefixed with the database name from developer 1's machine. When the table is expanded in this view the Catalog still shows as the DB name from developer 1's machine despite the connection properties above correctly showing the local DB name.
As I say this is a design time issue not a runtime issue.
Any ideas? Is there any way we can edit the Catalog name manually?

Try setting the Over ridden qualified Table Name
Set Datasource - > Tablename -> Properties
Double click Over ridden qualified Table Name, type name as shown in in the table name field above it.
Repeat for each table, this removes schema and db names associated with Table. Take a look at the SQL and make sure all tables are no longer prefixed.
Report should now be totally portable.

Processes 'stuck' after problems with database connection

First in the production environment, during database failover (MSSQL Server cluster), and later in testing, we encountered processes that are 'stuck' on some random operation. Admin console doesn't show stalled operation or branches, process is running, all operations are completed except last which was in several cases still in status Running, and in one case it was Completed but next operation was not started.
When operation is still running one would expect to select it and click 'Retry' in hope that process will continue but it seems there exist a bug in "Process Instance Detail" part of the admin console - it gives an error: "This operation cannot be completed without the selection of one or more operations from the list below!"
We can try using 'Terminate' for this operation and probably several that follow (because they would probably stall without data from first terminated operation) in hope that process which runs in big user loop can arrive at a step where it can recover from all this using existing data but it's messy and doesn't always work.
When the operation is in status Completed admin cannot do anything at all. This completed operation cannot be retried or terminated because selection box is grayed out. Process and data in it is irrecoverably lost and must be initiated from start.
I must say we had large problems before if database connection is lost even for few seconds (intentional fail over from one db node to another) - but now, when we filled check-connection-sql in datasource configuration Livecycle is behaving a lot better but still with above problems.
How can it happen that LC stops executing process workflow and stops on some operation just because it wasn't able to get valid db connection for several seconds? Is it some problem with transactions or what? What can I do? Where to look?
We are still on LC ES2 SP3. JBoss on Windows Server 2003 and MSSQL 2005.
Any help is appreciated.

I would suggest you to contact the Adobe support so they can look further in system as well as LC database.

How can I use SQL TOOLKIT concurrently with Database Connectivity ?

I have installed LabVIEW 6.1 with the Database Connectivity Toolkit and the SQL Compatibility Toolkit (e.g. _SQL folder). I am trying to make the transition from the SQL Toolkit VIs to the Database Connectivity toolkits, but for compatability with existing systems I would like to be able to run the two sets of VIs concurrently (but not in the same app).
When I read into 6.1 a connection VI that I wrote with LabVIEW 6.0 and the SQL toolkit the connection reference type gets changed from a number to type connection (see attachments) . Does compatbility mean that my SQL toolkit VIs are converted to a form compatible with the new ADO ?
Can I use the SQL Toolkit VIs or the Database connectivit
y VIs in the same installation of 6.1 ?
Can I have the SQL Toolkit VIs appear on the functions pallette and function as they did when only the SQL toolkit was installed ?

In response to your #2 below:
Actually it is possible to have the old SQL Toolkit and new Database
connectivity in the same installation of LabVIEW. I have only tried it on
6i, but don't see why it wouldn't work on 6.1. The trick is not to install
the SQL toolkit compatabitily VI's. The old SQL toolkit uses the Intersolve
dll through ODBC while the new Database connectivity uses ADO so it is
possible to use both methods not only in the same LabVIEW install, but it
the same running application. It has been a while since I originally did
this, so I am posting only to mention that it is possible and not exactly
how to do it. If anyone is interested in more details just respond.

Problem with database connectivity toolkit

I have problem with Labview database connectivity toolkit. I build and deploy the real_web.vi (attached to the post) to the web server. It seems that the DB Tools Open Connect can not connect to the data base, and it issues the following error:
NI_Database_API.lvlib:DB Tools Open Connec (String).vi->real_web.vi->real_web.vi.ProxyCallerADO Error: 0x80004005 Exception occured in Microsoft OLE DB Provider for ODBC Drivers: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified in NI_Database_API.lvlib:DB Tools Open Connec (String).vi->real_web.vi->real_web.vi.ProxyCaller
But in highlight execution, I do not get this error! My program connects to the database and read the data. What is wrong ?
Moreover, when I connect to the vi using the web-browser, the cpu usage of ApplicationWebServer process goes up to 100% (The same problem as stated in this post).

Say what you will about the problems that the DCT can cause (and goodness knows I have) my suspicion is that this is not a toolkit ptoblem. When ever something only works with execution highlighting on, two words should immediately jump to mind: "race" "condition".
Execution highlighting will muck aound with the order in which things get done in your code. Can you post what your code looks like?

my jdev version is 11 and i want do really simple task create new database connection to my oracle db.
I open database navigator and click new connection. i want jdbc connection but after i fill this form i pressed test connection button and get this error msg:
Test failed: 4
i think i have correct information but i tried this, i opened my older jdev 10 and copy jdbc url from my old db connection.
In jdev 11 i checked Enter Custom JDBS Url and pasted url from jdev 10 and i get:
Test failed: 4
What is wrong?
Thanks for your advice.
J.

I add new information:
i cant connect to oracle db 8, but i try another db in my company which is 10 and its working fine.
I write java class and try connect to db 8 via jdbc manually:
String url = "jdbc:oracle:thin:@SERVER:1525:SID";
String user = "user1";
String password = "aaa";
Class.forName("oracle.jdbc.driver.OracleDriver");
// DriverManager.registerDriver (new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection(url, user, password);
and i get this:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4

During down payment of asset po can any body solute the problem

the following message is coming during down payment of asset po
**purchase document allocated to asset**
Purchase document is allocated to asset
Message no. F5378
Diagnosis
The asset number assigned in the purchase document
is different from the asset number entered manually
cannot be transferred, because the 'Asset number' field was hidden for the account in question
System Response
In the first instance a warning appears, drawing your attention to the different account assignments. In the second instance an error message appears, because the asset number must be transferred from the purchase order but the necessary field is hidden.
Procedure
If you receive the warning, check which asset number is the correct number for this down payment.
If you receive an error message, you must either choose another special G/L indicator for down payments so that it is possible to assign an asset number to the relevant general ledger account, or you must change or delete the the specified purchase document number. Only those purchase documents are allowed which are not assigned to assets

mr. amit
we done that both field as a optional but still the same message is appear, i waiting for your kind supports
whenever like warning messgae appear on system how to identify that message related to which model. because always we have conflicted with itegrated modules.
thanks

Try resetting the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
and PRAM How to Reset NVRAM on your Mac - Apple Support
If those don't help you can try a cleaning disc or a quick shot of compressed air. Chances are that your drive has failed, join the club it's not all that uncommon. You can either have it replaced or purchase an inexpensive external drive. Don't buy the cute little Apple USB Superdrive, it won't work on macs with internal drives working or not.

Unable to access the objects with out schema as prefix.. can any body help

Hi,

but i created public synonym and gave all grants to all users also. but still i need to mention schema name as prefix otherwise it give the error..
can any body tell me reason and give me solution.
ex: owner:eiis table:eiis_wipstock
connect to: egps schema
in this position if i try with eiis.wipstock it gives error but if i mention like eiis.wiis_wipstock then its working fine.

The frist thing to try is a drive-n disk. They are cheap (US$5-15) and easy to use. Many unresponsive drives, even ones declared "dead" by an Apple tech, have returned to service after a cleaning.
Check with home entertainment specialty shops, electronic superstores and office supply outlets that sell computer accessories.

A .exe file is a Windows executable. OS X does not run Windows programs. If you need to use .exe files then you will need to install Windows on your Mac:
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak2, Vista, or Windows 7. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.
