I want connect my MS access file with Java GUI program,but I have problem with connection....
I have Windows 7 64b, and ms office 2007.
When I opened the ODBC driver manager in the control panel I havent found any driver for Microsoft Access (maybe when I started the ODBC is started running the 64bit ODBC, now I think is running the 32bit ODBC.
I read this and I make it :
"jdbc-odbc connection for window 7 64 bit machine..
1 . Right click Data source (ODBC)..go to properties change the folloing thing
target [ %SystemRoot%\SysWOW64\odbcad32.exe ]
start in : [ %SystemRoot%\System32 ]
press enter and continue as admin source: source link
"
) Now when I start in conctrol pannel the ODBC I can see the driver screenshoot
My program code(I tried two ways but I have same error):
public void Connect() {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
// String DatabaseFile = "D:java/Invertory.mdb";
// String DATABASE =
// "jdbc:odbc:Driver="
// + "{Microsoft Access Driver (*.mdb, *.accdb)};"
// + "DBQ=" + DatabaseFile;`enter code here`
String DATABASE ="jdbc:odbc:Driver= Microsoft Access Driver (*.mdb, *.accdb);DBQ=Invertory.mdb";
CONEX = DriverManager.getConnection(DATABASE);
} catch (Exception X) {
X.printStackTrace();
//JOptionPane.showMessageDialog(null,e);
}
}
error
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Use UCanAccess JDBC Driver :
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://<mdb or accdb file path>",user, password);
for example:
Connection conn=DriverManager.getConnection("jdbc:ucanaccess://c:/pippo.mdb");
So for your example it will be Connection conn=DriverManager.getConnection("jdbc:ucanaccess://"+path)
If you are using Windows 64-bit you probably need to go to this path
C:/Windows/SysWOW64/odbcad32.exe
Then I noticed that you are using the direct path instead creating new System DSN, your direct path is correct till the path to the access file you must give the full path like this :
jdbc:odbc:Driver= Microsoft Access Driver (*.mdb, *.accdb);DBQ=path/to/Invertory.mdb"
To get the path you probably need to use java.io.File that have a method returns the abslute path to the file see the example :
import java.sql.*;
public class TestConnection {
Connection con ;
Statement st ;
ResultSet rs ;
String db;
public TestConnection (){
try{
String path = new java.io.File("Invertory.mdb").getAbsolutePath();
db ="JDBC:ODBC:Driver=Microsoft Access Driver (*.mdb, *.accdb); DBQ="+path;
doConnection();
} catch(NullPointerException ex){
ex.printStackTrace();
}
}
public void doConnection(){
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection(db);
st = con.createStatement();
rs = st.executeQuery("select * from Invertory");
while(rs.next()){
System.out.println(rs.getObject(1));
}
}catch(SQLException | ClassNotFoundException ex){
System.out.println(ex.toString());
}
}
public static void main(String...argS){
new TestConnection();
}
}
I answered a similar question enter link description here a while back.
Basically at that time:
You could connect to Ms-Access from 32 bit java through the JDBC-ODBC bridge
You could not connect to a 32 bit Odbc driver through the JDBC-ODBC from 64 bit java. There was a message telling you that you can only connect from a 32 bit programs
While Microsoft does provide a 64 bit Ms-Access driver, it did not work with Java's 64 bit JDBC-ODBC driver.
Since then there seems to be a new open-source Ms-Access JDBC Driver Ms-Access JDBC driver. I have no Idea how good it is.
You just missing something in your code right here :
db ="JDBC:ODBC:Driver=Microsoft Access Driver (*.mdb, *.accdb); DBQ="+path;
You need to add {} between Driver= and )=; .
Like this Below
db ="JDBC:ODBC:Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ="+path;
final String fileName = "c:/myDataBase.mdb"
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ="+fileName;
Connection con = DriverManager.getConnection(url,username,password);
The problem is that you should run on Java 32 bit try to install latest JDK and it will work
I run it using JDK version "jdk-7u67-windows-i586.exe"
On a 64 bit system, you should:
run as admin accessdatabaseengine_64.exe
run java - 7-64 bit - jre.
if you are working in NETBEANS then after unzipping ucanacess.zip file add all jar file in the classpath using property window of project click on compile tab and add jar file then compile and test app.
JDBC-ODBC MS-ACCESS CONNECTION STOPPED WORKING IN JDK8. I solved the issue by installing JDK7 along with JDK8 in the same PC, once installed JDK7 I assigned it as the JDK version to use in my project as follows in Netbeans:
1.RIGHT CLICK THE PROJECT IN THE LIST > CLICK PROPERTIES
2.CLICK LIBRARIES ON THE LEFT NAVIGATION TREE
3.CLICK BUTTON MANAGE PLATFORMS > CLICK BUTTON ADD PLATFORM...
4.FOLLOW WIZARD, DESPITE IT SHOWS JAVA STANDARD EDITION CLICK NEXT
5.NAVIGATE TO C:\Program Files (x86)\Java AND SELECT THE FOLDER OF JDK7 > CLICK NEXT
6.THE FIELD AUTOFILL WITH THE RIGHT INFO... > THEN CLICK FINISH
7.SELECT THE JDK PLATFORM FROM THE LIST > CLICK CLOSE > OK
8.JDK7 SHOULD SHOW IN LIBRARIES PACKAGE.
JDK7 in Libraries Package
Click Back in Browser to return here after looking at the image...
From here on everything must run smoothly.
Hope it solves your problem.
Thanks.

I have a project in Java 7 and need to run it. The problem is that when I try to run I get the error
java.sql.SQLException: No suitable driver found for
JDBC:ODBC:Driver={Microsoft Access Driver (*.mdb, *.accdb)};
I tried most of the solutions suggested here but nothing is working. I tried to:
Add Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); to my code and it gives me error --> "java.lang.ClassNotFoundException: sun.jdbc.odbc.JdbcOdbcDriver"
Check if I'm using Java 7 -> System.getProperty("java.version") gives me 1.7.0_75
Added mysql-connector.jar
This is how I connect:
public static Connection GetConnection(String path) throws Exception {
String db = "JDBC:ODBC:Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ="+path;
Connection conn=DriverManager.getConnection(db);
return conn;
}
This is the full message (I'm using NetBeans):
Installed AccessDatabaseEngine
I never used ODBC, It may be that I need to configure anything in the 64-bit ODBC Administrator tool? Any suggestion?
Iam using windows 8.1 (64 bit) with microsoft office 32bit version. Iam trying to connect to an access file to retrieve username and password but the connection to the access database cannot be made, I have searched alot on the internet but can't seem to find a solution for this problem. I downloaded office 64bit with Microsoft Access Database Engine 2010 Redistributable but I still get the same error. What should I do to overcome this issue?
Java method:
dbcon()
{
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:db5");
}catch(Exception e){
System.out.println(e);
}
}
Error:
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
java.lang.NullPointerException
null
This may be the fact that your ODBC driver is 32 bit, which can not be recognized by the 64 bit Java. Either create a 64 bit ODBC driver or run Java in 32 bit mode (-D32 switch).
Try with the following connection string:
"jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=full_path_to_your_db_file"
I have to define a new Driver in the Netbeans "Services" Tab
Services->Databases->Drivers->new Driver...
because I want use the "Entity Classes from Database"-Wizard in context with UCanAccess.
1st step: "new Driver" does work (only declaration ;-) )
Driver File(s): f:\WorkspaceNetbeans\MSAccessDB\lib\UCanAccess-2.0.4-bin\ucanaccess-2.0.4.jar
Driver Class: net.ucanaccess.jdbc.UcanaccessDriver
Name:msaccess
2nd step: "Connect using..."
JDBC URL: jdbc:ucanaccess://F:/WorkspaceNetbeans/MSAccessDB/data/Datenbank2.accdb
"User Name" and "Password" leave blank
The "Test Connection"-Button results in Error Message:
Cannot establish a connection to
jdbc:ucanaccess://F:\WorkspaceNetbeans\MSAccessDB\data\Datenbank2.accdb using
net.ucanaccess.jdbc.UcanaccessDriver (Could not initialize class
net.ucanaccess.jdbc.UcanaccessDriver)
I've got the newest ucanaccess from http://ucanaccess.sourceforge.net/site.html
ucanaccess-2.0.4.jar, commons-lang-2.6.jar, commons-logging-1.0.4.jar, hsqldb.jar, jackcess-2.0.3.jar in the Netbeans Classpath.
The old fashion way to connect via jdbc to ucanaccess works fine.
public static void main(String[] args) throws ClassNotFoundException, SQLException {
String connectString = "jdbc:ucanaccess://" + "f:/WorkspaceNetbeans/MSAccessDB/data/Datenbank2.accdb";
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
Connection conn = DriverManager.getConnection(connectString, "", "");
conn.createStatement().execute("CREATE TABLE example1 (id COUNTER PRIMARY KEY,descr text(400), number numeric(12,3), date0 datetime) ");
}
The same connection string also works fine make DBeaver able to connect to the MSAccess db.
My set up:
Windows 7 Professional 64 bit
Microsoft Office 2013
NetBeans IDE 8.0
Java 1.8
The problem is similar to: "Conflict between JT400 and UCanAccess?" Conflict between JT400 and UCanAccess?
but the answers there don't help with my problem.
Any ideas to solve my problem?
UCanAccess 2.0.4.1 has been released, now you can configure UCanAccess as NetBeans service.
As explained in the UCanAccess web site (tab 'jdbc client tools') you have to:
-in the field Driver File(s), add ucanaccess.jar and all dependencies. I've upgraded the commons-logging in the UCanAccess distribution to the 1.1.1, so you can use that jar with NetBeans8.
-use the following pattern for the jdbc url:
jdbc:ucanaccess://;showschema=true
Showschema connection property must be setted to true.
I was wrong, it wasn't a tricky task but...
To establish the connection you have to list in the Driver File(s) :
ucanaccess-2.0.4.jar,
commons-lang-2.6.jar,
hsqldb.jar,
jackcess-2.0.3.jar
AND
a different version of commons-logging that you can find it in NetBeans:
NetBeans 8.0\ide\modules\org-apache-commons-logging.jar (the commons-logging in the UCanAccess distribution is in conflict with that used by NetBeans)
But unfortunatly, after establishing the connection, you won't be able to execute queries through this IDE, because of a trivial bug in the UcanaccessDatabaseMetadata which hasn't effect with the other IDE jdbc clients I tested (Openoffice, Libreoffice, DBeaver, Squirrel, SQLeo and so on) .
So, to do this, you have to wait some days (I think I'll post a patched Ucanaccess 2.0.4.1 next week). Also, I'll add a note about UCanAccess configuration as NetBeans service in the UCanAccess web site.

The infamous java.sql.SQLException: No suitable driver found
(21 answers)
Closed 3 years ago.
I am working on a web application where I am creating MSSQLSERVER 2008
database dynamically.
But it's giving me
java.sql.SQLException: No suitable driver found for jdbc:sqlserver://localhost:1433;databaseName=master
My code is:
String dbName = "db1";
try {
String url = "jdbc:sqlserver://localhost:1433;databaseName=master";
Connection connection = DriverManager.getConnection(
url,
"sa",
"roshan14121987");
Statement statement = connection.createStatement();
String sqlquery = "CREATE Database \"" + dbName + "\"; ";
statement.executeUpdate(sqlquery);
statement.close();
connection.close();
} catch(Exception e) {
e.printStackTrace();
}
I have added sqljdbc4.jar in lib. I have tried it on both NetBeans (with GlassFish and Tomcat Server) and Eclipse IDE(Tomcat Server).
On the other hand I have tried this with simple desktop application, it's working fine on both IDEs. With sqljdbc4.jar added in lib.
Before calling DriverManager.getConnection() you will have to load the SQLServer JDBC driver. You can do Class.forName("xxxx"); where xxxx is the appropriate driver class (fully qualified name with package prefix).
EDIT: Do this Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); to load the driver. Refer MSDN link for more.
Is sqljdbc4.jar in your war file under WEB-INF/lib. This is the alternate location to $CATALINA_HOME/lib and recommended to keep your web application self-contained. Further, if you should ever need to change servers, you need only drop the war into your webapps directory.
You might also need a Class.forName([database class]).newInstance, but that isn't necessary using a JDBC 4.0 driver. Good luck and if you have further problems, do leave a comment.
The error happen in the runtime on Tomcat Server,right? I think you need to make sure your sqljdbc4.jar deploy the in the Server.
I'm really looking at a mystery here. I created a Java program in Eclipse and established a JDBC connection. The code is the following:
import java.sql.*;
public class Login {
public static void main(String[] args) {
try {
// Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection connection = DriverManager
.getConnection("jdbc:sqlserver://localhost;databaseName=testdb; integratedSecurity=true;");
//adding port 1433 doesn't make a difference
System.out.println("Connection successful");
Statement st = connection.createStatement();
ResultSet rs = st.executeQuery("select * from testtable");
while (rs.next()) {
line = rs.getString(2);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
When I'm running it within eclipse, everything's fine. The database and tables are good, library and authentication in the Java Built Path are set and I get the result I want, namely "Hello World", which is a string in the selected table.
But creating an executable JAR file and running it throws the exception "This driver is not configured for integrated authentication". It does not even connect, so even if there was an error in the database it wouldn't matter at this point.
Even more confusing is the fact, that some weeks earlier, I also created an executable JAR file and it worked!
OS: Windows Vista Home Premium x86
JDBC driver location: "C:\sqljdbc_4.0\enu\sqljdbc4.jar"
Native library location: "C:\sqljdbc_4.0\enu\auth\x86"
Java version: Java 7 Update 17 and JDK 7 Update 17
Previousely, I used Update 21, but I changed back to check if the driver could be the reason.
So, any suggestions? I'd be very grateful!
Check the runtime classpath of eclipse, then try to create a system level "CLASSPATH" variable and add the same path. Once the variable is set, execute it in new command prompt or reload the environment variables
Make sure your executable jar has the dependency in MANIFEST.MF for all the necessary jars (along with MainClass)
Finally, It is always a practice in Java to make the first alphabet in Capital ("Login" instead of "login")
Actual problem is that if you run your project from eclipse, it will automatically add run arguments that are defined in run/run config//arguments, so you run your program with properly set path to sqljdbc_auth.dll. But if you export your application to .jar file and just run it, you will get these errors cause there is no correct classpath to auth file.
So, if you run your app from command line with proper arguments, it should be working.
