Problem with JDBC ODBC connectivity

I am trying to connect to MS access database with jsp page. This is sample from my js page :
String SUN_DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";
Class.forName(SUN_DRIVER);
String aDataSourceName = "puneet";
String url = "jdbc:odbc:" + aDataSourceName;
Connection con;
con = DriverManager.getConnection("jdbc:odbc:puneet","","");
The last line gives me the follwoing error :
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
puneet is name of my datasource and it points to my .mbd file.
I dont have anyusername or passwords for this daatsource.
I am using Tomcat/4.1.18-LE and jdk1.4
I have also added rt.jar in the classpath
pls help

Hi pg4,
May be your dsn is not pointing to .mdb file. Check it by putting your mdb file right where your code is and then user following syntax which is called dsn-less connection. It helps you to connect to the target mdb file with out any need of dsn.
String url = "jdbc:odbc:;Driver={Microsoft Access Driver (*.mdb)}; DBQ=yourDBFile.mdb";

Problem with jdbc:odbc returning incorrect number of rows.

Hello,
Am sure i have done something stupid, but i have an issue with jdbc:odbc ....
It is a simple sceanrio that i have coded umpteen times before ...
I have the following ....
1. Connection to DB2 on an IBM i5 (I apologise for not using native drivers from jt400.jar, but i had an ODBC code example and was in a rush - no excuse i know)
2. Statement object created from connection above
3. A string with my SQL in it
4. A result set for the results.
These are created as follows:
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection(ODBCSource, userID, password);
if (con == null) {
// error handling not relevant here
} else {
Statement s = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
String SQL = "select * from table";
ResultSet rs = s.executeQuery(SQL);
i then try to loop ....
while (rs.next() )
// stuff
however, i only ever get one result .... if i stick in the check for isLast, the first loop hits this check, i get my little status message, and the loop ends.
while (rs.next() )
if (rs.isLast() )
System.out.println("I am on last record");
BUT if i run the SQL
"select count(*) from table" ... i get a count of 148 !!
I tried setting the FetchSize through setFetchSize(), but made no difference.
This is running on a JBoss server 4.2.1GA, JDK is "jdk1.6.0_02" .... i have a suspicion that this may be a JBoss specfic issue, as this exact code runs just fine on the Domino platform that it was originally on, if this is the case, i apologise for wasting everyones time .... but would still appreciate any pointers you can give me.
Cheers

Hello,
Thanks for the reply, I am not sure i follow what you are saying.
I only mentioned JBoss as it is the application server that we have deployed to and because the orignal code ran fine on a Domino server, I will take your advice and try to run it through in debug rather than running actually on the application server.
Am i incorrect in my assumption that if "select count(*) from table" gives a count of 148, i should expect 148 records in a result set created from "select * from table" ? This is all rather new to me so i apologise if this is incorrect, I'd love to know why this is incorrect so i dont make similar mistakes in future.
Also, If i run this same code on the previous platform, i get 148 iterations of the code contained within
while (rs.next() ) { ... }
When the war file is deployed to JBoss, the same SQL statement gives a result set that only iterates once for
while (rs.next() ) { ... }
The previous platform as I say was domino, but it was running as a lotus notes java agent (despite not using any notes documents etc) as it happened to be where the web pages that call this process were located. It is possible that some of the main code has changed as I had cut and paste the code into a servlet using MyEclipse, but i have double checked the bit that does this SQL request and it is identical
To complete the picture, the new servelt is then called from the action tag on the submit form on a JSP, when it ends the servlet redirects via the requestdispacher to success or failure jsp pages depending on the outcome of the processing.
Thank you again for your help.

Problem With Jdbc-Odbc BRidge Connection

I get The following error
SQLException:[Microsoft][ODBC Driver Manager] Invalid cursor state
when using the code
whats the problem with it
import java.sql.*;
public class Employee {
String DBurl;
Connection con;
public Employee(String url)
DBurl=url;
void queryTest()
String query="SELECT * FROM EmpTable";
ResultSet result;
Statement stmt;
try{

catch(java.lang.ClassNotFoundException e){
System.err.println("Class not Found Exception:");
System.err.println(e.getMessage());
try{
con=DriverManager.getConnection(DBurl,"myLogin","mypassword");
stmt=con.createStatement();
result=stmt.executeQuery(query);
System.out.println("ID"+"\t"+"Name"+"\t"+"Rate"+"\t"+"DeptID");
System.out.println("--"+"\t"+"----"+"\t"+"---"+"\t"+"----");
while(result.next());
String name=result.getString("Name");
int ID=result.getInt("ID");
float rate=result.getFloat("Rate");
int deptID=result.getInt("DeptID");
System.out.println(ID+"\t"+name+"\t"+rate+"\t"+deptID);

con.close();
catch(SQLException ex){
System.err.println("SQLException:" + ex.getMessage());
public static void main(String args[])
Employee app = new Employee("jdbc:odbc:Employee");
app.queryTest();
}

here's your mistake:
while(result.next()); // <--- the loop body is empty.Remove the semi-colon.

Im really stuck!!! any suggestions? thanks in advance

Thank you for your response and sorry for the length
of code,
Thats was my first idea that it was asking for
or something I dont have but I checked my database and
I dont have any unusually large data entries (most
between 8-15 letters, the others are numbers) could it
be something wrong with how I've entered the database
in MsAccess, or am i barking up the wrong tree again!
Many thanks
RobI think you've misunderstood me. This has nothing to do with unusually large data entries, but rather the opposite. You are wrongly expecting data that is shorter than you think. When you call rs.getString(i) to retrieve a column value of a field, and you only want the first 5 characters in the column (instead of 10 or whatever the column size is), you would do something similar to the following:
String column_value = rs.getString(1).subtstring(0,5);The above expects a String that is at least 5 characters. Your problem is when your column value returned is less than the specified substring index ( in this case 5 ) it will throw an exception. If you changed your code to this, the error will not occur:
String column_value = rs.getString( 1 ).subtstring( 0, 5);
if ( column_value.length() > 5 )
column_value = column_value.substring( 0, 5 );

Newbie: Problem with jdbc-odbc and MS SQL server 2005

I'm on win vistax64 with SQLSERVER 2005 and I have set up the odbc source as system dsn using the SQL Native Client driver with SQL authentication and the connectivity test in the end succeeds.
I'm trying to make a simple web app that will connect to the database and perform simple querries. It's a school assignment.
I'm using the jdbc-odbc bridge because it's the simplest way to do it and it's what we were shown in class.
I get the following irritating error:
"Cannot establish a connection to jdbc:odb:sstmdb using sun.jdbc.odbc.JdbcOdbcDriver ([Microsoft][ODBC Driver Manager] Data source name not found and no default driver specifies)".
I'm working with netbeans 5.5.1 and this error is what I get when in the runtime tab I try to connect with the jdbc-odbc. I get a similar error in the logs when I try to run the app on the j2ee server.
This is the java class that establishes the connection.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Connector {
    private static final String dbUrl="jdbc:odbc:sstmdb";
    private static final String user="kimon";
    private static final String password="jackohara";
    public static Connection getConnection(){
        Connection conn = null;
        try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            conn = DriverManager.getConnection(dbUrl,user,password);
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        return conn;
}It has worked perfectly on my school PC with winXP and MSDE2000.
What am I missing?

Ok, help came from an other way where I was inquiring about a different problem:
Connectivity works fine by using User DSN instead of System DSN for the ODBC source.

Problems with JDBC-ODBC Driver

oh now i understand.
i got a very unknown company which supplied the ODBC driver, but they dont have java driver...
so I have nothing to do about it?The choices are find a different driver or use the one you have.
The one you have doesn't do batches.
Finding a different driver could involve the following.
- Buying one from somewhere else
- Pay someone to write one.
- Write a driver yourself.
All of those are somewhat dependent that the "unknown company" has an API that supports that. You (or someone) could also figure out the file format of the "unknown company" as well and then write one.

Problem with JDBC-ODBC bridge

OS in my PC is Windows7 Ultimate(64-bit), and I had JDK1.7.0_21(compatible with my PC), Oracle 10G ExpressEdition(32-Bit), ApacheTomcat7.0.11(compatible with my PC).
As my OS is 64-BIT, I accessed C:\Windows\SysWOW64\odbcad32 and I selected UserDSN tab->Add->Microsoft ODBC for Oracle->finish,tapply->ok. Then a Dialog Box appeared and I entered a DSN name=ramsdsn and my DATABASE USERID=rams in username->ok->apply->ok.
But when I tried to compile my program using:
DriverManager.getConnection("jdbc:odbc:ramsdsn","rams","rams");
I got an error:java.sql.SQLException: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application
Help me FRNZ.. I have been trying it for 7 days and I'm tired of it and I could not figured it yet...
THANKS in Advance...

Wrong database is the most likely reason.
Note that the ODBC driver is not a good driver for MS SQL Server. It handles varchar as chars. So an insert of 'A' into a varchar(25) will end up with 'A' followed by 24 spaces. And that probably isn't what you want your varchars to do.

Problems with jdbc:thin connection to oracle9i RAC

Hi,

Any help would be greatly appreciated.

Dear Maran,
Yes! You can always increase the number of process and session to a higher limit at database end, but it won't be a feasible solution. Rather look into the areas which are the cause of this and try to solve them out.
What if you increase these parameters at database end to accomodate more and more sessions, and allow them to use more and more resources like process, and still they keep on increasing rather than getting closed. It would be worthless use of Database server Reources.
It is really very simple, just look for the SQL statements which are having last_call time a long back (from V$SESSION and V$SQLAREA or you may use tools like TOAD), and try to find out the reason why they are not releasing the connections back to Connection Pool. Check out these SQL statements in the application code and ensure Connection Handling is done over them.
Some "RS.CLOSE" type of command is there in java (I am not sure with the proper syntax)
Regards,
Manoj.

I have a problem with JDBC Realm in Tomcat/Oracle/Win XP

I have a problem with JDBC Realm in Tomcat.
I have attached my server.xml file located in the
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\server.xml
The Problem is that when I login I get the user name and password prompt but it does not resolve.
When I enter in the tomcat-users.xml password with memory realm uncommented it works fine.
C:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\tomcat-users.xml
Is there a cache or something I need to reset for the JDBC Realm to work?
I have attached my tables and contents as well...
Did I miss something????

A very surprise problem about JDBC and connection pool

I occur a very problem about JDBC and connection pool on Weblogic Platform
8.1.
There is a table in Oracle
Table
Name: t1
id varchar2(5);
content clob;
id is primary key.
If I use a connection pool to connect to Oracle,like following program:
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("cgOracleDataSource");
con = ds.getConnection();
then following program will throw a ClassCastException
String sql = "select content from t1 where id = ?";
PreparedStatement pst = con.prepareStatement(sql);
pst.setString(1,"001");
oracle.sql.CLOB clob = (oralce.sql.CLOB)rs.getClob("content") //this
statement will throw ClassCastException
but if I use JNDI to connect to Oracle,like following program, then those
program above is ok
private String dbdriver="oracle.jdbc.driver.OracleDriver";
private String dburl="jdbc:oracle:thin:@192.168.7.148:1521:ep";
private String username="ep";
private String password="epuser";
Class.forName(dbdriver);
conn = DriverManager.getConnection(dburl, username, password);
conn.setAutoCommit(false);
On the contrary, if I use JNDI to connect to Oracle, following program will
throw ClassCastException
weblogic.jdbc.vendor.oracle.OracleThinClob clob =
(weblogic.jdbc.vendor.oracle.OracleThinClob)rs.getClob("content");
but it is fine if I use connection pool to connect to Oracle.
I am confused this problem, who can tell me why?
Daniel

When you are getting connection using datasource lookup from weblogic
connection pool, this connection is internally wrapped and hence you have to
cast it to weblogic.jdbc.vendor.oracle.OracleThinClob which you do and so it
works.
But when you get connection by loading driver straight, you are getting naked
oracle connection. In this case when you cast it to oracle.sql.Clob it works,
as you have seen in your test case.
I hope this explains what is going on with your code.
Thanks,

I occur a very problem about JDBC and connection pool on Weblogic Platform
8.1.
There is a table in Oracle
Table
Name: t1
id varchar2(5);
content clob;
id is primary key.
If I use a connection pool to connect to Oracle,like following program:
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("cgOracleDataSource");
con = ds.getConnection();
then following program will throw a ClassCastException
String sql = "select content from t1 where id = ?";
PreparedStatement pst = con.prepareStatement(sql);
pst.setString(1,"001");
oracle.sql.CLOB clob = (oralce.sql.CLOB)rs.getClob("content") //this
statement will throw ClassCastException
but if I use JNDI to connect to Oracle,like following program, then those
program above is ok
private String dbdriver="oracle.jdbc.driver.OracleDriver";
private String dburl="jdbc:oracle:thin:@192.168.7.148:1521:ep";
private String username="ep";
private String password="epuser";
Class.forName(dbdriver);
conn = DriverManager.getConnection(dburl, username, password);
conn.setAutoCommit(false);
On the contrary, if I use JNDI to connect to Oracle, following program will
throw ClassCastException
weblogic.jdbc.vendor.oracle.OracleThinClob clob =
(weblogic.jdbc.vendor.oracle.OracleThinClob)rs.getClob("content");
but it is fine if I use connection pool to connect to Oracle.
I am confused this problem, who can tell me why?

Problems with n97 apps connecting to network (Voda...

Problems with n97 apps connecting to network (Vodafone UK – 3G)
Recently a number of my apps which used to connect automatically to the internet (which ever was available – known wi-fi or 3g) have stopped doing this. They now only connect to one known wi-fi.
I’ve tried uninstalling and reinstalling each app, but this hasn’t solved the problem. I’ve checked for software updates and do not believe any have been applied or are available. All apps have been downloaded via Ovi on the phone. I still am able to access the internet by the web browser which was installed on the phone and via google maps (which also still manages GPS position, search, etc).
The apps which I notice causing a problem are:
Sainsbury’s/nectar
Tesco
Map my tracks
Snaptu
Opera Mini
Any one got any ideas???

I have the same problem since i updated my mac to 10.5.6.
Each time I have to do a diagnostic and retype the WEP password to have the internet connection.

I am having problems with the wifi connection on my ipad 4th generation only 3 weeks old. Have left it back to the shop i bought it in and they said they have to send it away now i am left with no ipad. What after sales support do you give really?

Does anyone else have problems with the wifi connection on their 4th generation Mine keeps going off line and its only 3 weeks old.I had the ipad mini and this problem never existed. I brought it back to the shop where i bought it Expert Laois last week and they said they couldnt find a problem but had to take it back today as it keeps disconneting from wifi still, anyway they are sending it back for repair and it am left with no ipad. After spending in excess of 700e i feel that this is really bad after sales service. I bought something that i want to use now and cant so what a waste of money it is .

Thankyou, but the shop said that they spoken to apple and that they have now changed their policy and that they do not give a replacement. So are you telling me that their information is false. Also what should they have done. This problem has existed since i bought it.????? What should i do?????

To map the drive on your computer click on Start - RUN - type "\\192.168.1.1" and click ok... When prompted for Username and Password type "admin" and click ok... Now you will be able to see the folder which you have shared on your router, right click on it and select "Map network drive" and click on finish.
Now it will map the drive on your computer and you should be able to transfer the file from your computer to the USB drive.

Some progess I see. To be honest, i would not waste your time with trying to connect using wireless.
You are likely to get poor connections and dropping out.
If its working using a cable, then there is no need to bother with giving me the network settings, bu see how it goes, because sometimes giving the TV a static IP address can give better results.
There is an example of a couple of powerline adapters on the diagram below. Just ignore the network switch unless you want to connect other devices which are near to the TV.
