Database connection to ODBC bridge

Hi!
I can connect to an ODBC (Access) database and I can see tables in Oracle JDeveloper 9i. It's work fine.
I can connect to an ODBC (Access) database but I CAN'T see tables in Oracle JDeveloper 10g. It's NOT expanding table items.
Why?
Thanks...

This is a bug in the JDeveloper 10g Preview release. It will be fixed in the production version.

Weblogic server using jdbc-odbc bridge

I want to connect to database through jdbc-odbc bridge.I am using web logic server. When i creating new jdbc connection pool a error comes that driver class is not on classpath. how i rectify this problem? how I make weblogic to recognize sun.jdbc.odbc.JdbcOdbcDriver?

like any other library...
put the .jar file of the lib in the WEB-INF/lib of
your webappWrong in so many ways.
You don't add drivers to WEB-INF/lib if they're being acquired as datasources - the server needs access to the driver to create the data source. If you're not using a DataSource but materializing the connection directly, then this advice is semi-correct, but it's a crappy way to build a web app.
You don't normally add a JAR for the Sun JDBC ODBC bridge anyway as it's present by default in their J2SE implementation.
And finally, I think WebLogic doesn't use the Sun J2SE implementation anyway, so it's possible that the bridge is not available at all.
So the correct answer is: Don't use the bridge driver. Acquire a driver for your specific database and use that. And make sure that it's available to the application server. If you absolutely must use the bridge driver, you're going to have to use the Sun J2SE implementation to run WebLogic - and I think you'll have to consult the WebLogic site for help with that.

JDBC-ODBC-Bridge connection to SQL Database

Hi guys
I have a problem. I've made a little game which I want to put on my website. It has a highscore-list which I want to connect to my web host's database server to get the current list.
I tried this with JDBC and got it to work locally but when I uploaded it to my site it didn't work. I contacted my web host's technical support who told me that their server didn't have the JDBC driver and that I should use ODBC instead. I did lots of reading and found out about this JDBC-ODBC-Bridge. I have since been trying to implement this into my program but hasn't been successful.
In my original JDBC connection I used
private String url = "jdbc:mysql://" + host + "/" + mydatabase;
Class.forName("com.mysql.jdbc.Driver");
Connection connection = DriverManager.getConnection(url, username, password);Now I'm trying
private String url = "jdbc:odbc://" + host + "/" + database;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection connection = DriverManager.getConnection(url, username, password);But, at least when trying it locally, I get the error
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name is too long.

Remote Database connection throught JDBC-ODBC

Hi everybody
I've developed an application which connects to a MS Access database throught the JDBC-ODBC bridge; if the database is on my local machine I've no problem at all, but I now need to connect to a database on a remote PC. I've set the DSN entry for the database on the remote computer and try to connect using something like:
String db_name="jdbc:odbc:remote_pc_name\\\\DSN_db_name";
Properties db_prop=new Properties();
db_prop.setProperty("user","username");
db_prop.setProperty("password","user_password");
Connection dbconn=DriverManager.getConnection(db_name,db_prop);
but the ODBC driver gives me the message
"[Microsoft][ODBC Driver Manager] DSN not found and driver not specified.
I've tried other possible "connection strings" but I always get the same message.
The software works properly if I connect to the local DB with:
String db_name="jdbc:odbc:DSN_db_name";
Any idea how to connect to a remote DB through ODBC?
Thanks

No need for a separate thread really is there? its still relevant to the original.

JDBC ODBC bridge connections using 2.1.1

Hi,
I have reviewed a lot of postings related to JDBC and third party drivers and understand how to connect to the packaged drivers such as MySQL and MS SQL Server/Sybase. Where I'm stuck is the reference in the Connections help to JDBC. We have a ODBC system DSN that's not part of the existing JDBC drivers. The help implies it's possible to create a JDBC:ODBC bridge connection and that JDBC:ODBC bridge functionality is part of the JDK therefore should not require additional jar files. However, the JDBC tab is not an available connection type by default. I traced the JDBC ODBC bridge to the rt.jar and tried adding that to the third party extensions but that has not resulted in the JDBC tab becoming available.
Is the JDBC tab only available when using commercial JDBC ODBC bridge drivers ?
For all other connections (DB2, TimesTen, Teradata etc) the help is very specific about which jar files you need and any other requirements but the JDBC section it is unclear how you enable JDBC connectivity.
Thanks
Steven

We are using the JDBC-ODBC bridge to do a prepared
statement. I have seen other bugs that suggest this
is problematic with older version of JRE, but was
supposedly fixed in later versions.
java.sql.SQLException: General errorIf it is not too late, check the following link:
http://java.sun.com/j2se/1.3/docs/guide/jdbc/getstart/GettingStartedTOC.fm.html
Sections 6.1.3 and 8 (especially tables at the end).
I had the same case, and the problem was that the field in the Oracle database was defined as NUMBER(4), witch is equivalent to INTEGER in JDBC types, and function setInt should be used with INTEGER, instead of setLong.
This is explained in sections I mentioned.

Jdbc-odbc-bridge connection pool

I got a problem with odbc connection pool in my Sun App Server 7.
When i try to connect to the odbc database (msaccess or conzept16), i got a SQLException : com.sun.enterprise.repository.J2EEResourceException
java.lang.NoSuchMethodException: setdatabaseName .....
It seems that i cant set any propertys like url, user or password. The exception throws every time NoSuchMethodException: setURL or ... NoSuchMethodException: setUser
I tried this with pointbase database and pointbase drivers and there was no problem. Also when i connect direct from jsp page to the odbc database without connection pool it works.
How can i set a propper connection pool with the jdbc-odbc-bridge? Please Help. There is no jdbc driver for that database available.
Is that right using sun.jdbc.odbc.JdbcOdbcDriver for that?
here my server.xml
<resources>
<jdbc-resource enabled="true" pool-name="access-pool" jndi-name="jdbc/AccessDB"/>
<jdbc-connection-pool steady-pool-size="2" max-pool-size="6" max-wait-time-in-millis="60000" pool-resize-quantity="2" idle-timeout-in-seconds="300" is-isolation-level-guaranteed="false" is-connection-validation-required="false" connection-validation-method="auto-commit" fail-all-connections="false" datasource-classname="sun.jdbc.odbc.JdbcOdbcDriver" name="access-pool" validation-table-name="TAB_NAME">
<property value="jdbc:odbc:testdb" name="databaseName"/>
</jdbc-connection-pool>
</resources>

AFAIK the bridge driver does not support multipleopen
connections (which is what connection pooling
requires).Wrong.
It might be the case that the bridge AND ms access
does not support that but I seriously doubt that as
well.
Yesterday I didn't want to test this. Today I did.
So I can state that it is completely wrong.
There might be some other reason preventing the usage in a pool, but it isn't the number of open connections.

JDBC-ODBC bridge connection failure.

I'm new to JDBC and JDeveloper and am having some difficulty
getting through the database applet tutorial.
I'm trying to connect to a Microsoft Access database using the
JDBC-ODBC Bridge. This is an interim stage before using a Linux
Oracle database which is not yet up and running.
When trying to add a data form, the database wizard fails at
step 4 of 7 after selecting the Sun JDBC-ODBC bridge and the
required data source the following error is presented:
Connection error
Vendor code 84
[Microsoft][ODBC Microsoft Access 97 Driver]Driver not capable
I also tried setting up (using ODBC manager) a System DSN for a
text and Excel data source, but met similar problems e.g:
[Microsoft][ODBC Excel Driver]Driver not capable
Currently JDeveloper Beta 2.0 (build 184) and the ODBC source
are on the same NT4.0 (SP4) machine.
To confuse matters I'm actually running Access 95, rather than
Access 97.
I have previously successfully connected to an Access ODBC
source via JDBC in a Java application (not applet) when
following a tutorial example that comes with the Sun JDK 1.2. I
note, however, that jdbcodbc.dll that's part of JDK 1.2 is newer
(and bigger - 32K 01Dec98) than that supplied with the
JDeveloper Beta 2.0 (22K 05Nov98)
I'm a bit lost with this problem since nothing happens after
pressing help on the error dialog, and I'm not sure where to
look for log files etc. to further debug the problem. Any help
would be gratefully received!
null

The error indicates that the bridge is making a call to the
driver which it cannot handle -- either because the call is
invalid/unreasonable or because the driver doesn't implement the
functionality requested. An ODBC trace will determine which of
the two is true. If the first, you need to contact the bridge
provider to get a fix. If the second -- the ODBC driver
provider.

Jdbc non-odbc-bridge for Access mdb database

I would like to have my Java program be able to use a MicroSoft Access-97 or Access-2000 mdb database. I don't want to use an odbc driver, but instead use a type-2 or 3 or 4 driver (preferrable type-4).
Does such a driver exist? This is for a freeware project, and I would prefer a free or very low cost driver.
I'm not sure I fully understand the differences between jdbc types. My impression is that an odbc-bridge driver requires that the end-user setup the odbc connection. I'd like to avoid that if possible.
My intent is to distribute the application with the MyApp.mdb database file, and have MyApp be able to use the database without user setup.
I suppose an alternative would be to programmatically create the odbc-bridge data source configuration. Is that possible from a java program, and, if so, how? I can do this with Visual C++, but not clear on how to do in Java

Searching the forums is always a good idea.
From one of the previous times I answered this.

Database Connection Error 42000:[Microsoft][ODBC driver for oracle] Syntax

Hi,
This is Sathish, I am trying to create a report and retrieve data through stored procedure using ODBC Connection. When connecting to the Stored Procedure it is showing Database Connection Error 42000:[Microsoft][ODBC driver for oracle] Syntax error or access violation' Error.
CRXI R2, Oracle 9i.
What do i do to solve this issue.
Regards,
Sathish

Hi Satish
It could be an issue with the driver.
You can try with the OLEDB n Oracle native connection to test if the issue persists.
Also you can refer to the [Troubleshooting Database Connectivity for Crystal Reports|http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/d05b3bb7-0f28-2c10-4ea3-84dbdc4e414e&overridelayout=true]

JDBC-ODBC bridge for MSSQL database

Hi,
I have SAP 2 MSSQL synchronous scenario and I need to select data from MS SQL 2005 database located on the remote system via XI 3.0. The database provides only ODBC access. I am using JDBC receiver and I would like to use sun.jdbc.odbc.JdbcOdbcDriver as a driver. I searched this forum, but the most of threads describe, how to connect to MS Access database, which is not my case. I used XI JDBC/FTP connection Test and XML Validation Application described in SAP Note 1085539 to test it. I used the following settings:
Driver Class (fully qualified)   sun.jdbc.odbc.JdbcOdbcDriver
JDBC URL                          jdbc:odbc:Driver://<host IP>;databaseName=<name>
User Name                         my username
Password                           my password
I got the following error:
Exception Occurred : [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Exception Stack Trace : java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
     at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6958)
     at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7115)
My questions are: Is it possible to use sun.jdbc.odbc.JdbcOdbcDriver in this scenario? If so, what should I put as JDBC URL? Do I need to create DSN on the XI system? (it is a Windows NT based machine).
Thanks a lot for your answers.

Have you already deployed the drivers (msbase.jar, mssqlserver.jar, msutil.jar) ??
If so,
The JDBC drivers should be:
com.microsoft.jdbc.sqlserver.SQLServerDriver
And the connection should be:
jdbc:microsoft:sqlserver://hostname:1433;DatabaseName=name
else

Jdbc-odbc bridge with Connection pool datasource

I have created a little j2ee app in which an enterprise bean accesses a ms sql server table by creating a JNDI datasource using sun.jdbc.odbc.JdbcOdbcDriver. I can successfully deploy it and run it on the jsdkee 1.3 J2EE server. However, when I attempt to deploy it on WebSphere 4.0 AES, the app fails attempting to make the database connection. The error log states: "Unable to connect to database: the class (sun.jdbc.odbc.JdbcOdbcDriver) does not implement javax.sql.ConnectionPoolDatasource or javax.sql.XADatasource". Which, of course, is probably true, but is there a WebSphere workaround? There is nothing remotely related mentioned at the IBM WebSphere site.

Thx. So far, I have not found a readily accessible free alternative driver that supports connection pooling. The drivers list notes several corporate offerings that do; freetds may work but I don't know yet. If it does, I will update this discussion.

Tables not displayed in ODBC database connection (9.0.3.1035 Prod)

Hi,
In 9.0.3 production release, I have created a ODBC connection to a data source. When I open the connection, it shows all the schemas, but when I expand to see the tables, it shows none. I have tested the same in 9.0.2 and it works there. In Tools->Preferences->Database Connection, the two check boxes for "Show all oracle schemas" and "Generate PL/SQL debug " are turned off.
I ran an SQL select in "SQL worksheet" on one of the tables wihtout any problems, but the tables do not show up under schema.
Any suggestions?
Thanks, Raju

What database/odbc driver are you using? It's possible that the way the driver is returning the metadata that JDev can't figure out where the tables are located.

Connecting remote FoxPro dbf file using jdbc odbc bridge driver?

Hi all,
I am new to this topic, (even I read some threads)
I need to access some FoxPro tables (dbf files) and select some data and save to an oracle table. what is the best method to do this?
If I use java as development tool. which other drivers or methods to use beside jdbc-odbc driver?
I read from this link but I didn't understand.
http://java.sun.com/products/jdbc/faq.html#5
"5. How can I use the JDBC API to access a desktop database like Microsoft Access over the network?
Most desktop databases currently require a JDBC solution that uses ODBC underneath. This is because the vendors of these database products haven't implemented all-Java JDBC drivers.
The best approach is to use a commercial JDBC driver that supports ODBC and the database you want to use. See the JDBC drivers page for a list of available JDBC drivers.
The JDBC-ODBC bridge from Sun's Java Software does not provide network access to desktop databases by itself. The JDBC-ODBC bridge loads ODBC as a local DLL, and typical ODBC drivers for desktop databases like Access aren't networked. The JDBC-ODBC bridge can be used together with the RMI-JDBC bridge, however, to access a desktop database like Access over the net. This RMI-JDBC-ODBC solution is free.
"

Another solution by using HXTT DBF, a commercial type 4 JDBC package: You should read Remote Access Questions section at http://www.hxtt.net/en/software/dbf/faq.html#remote .

What's the URL in a JDBC-ODBC bridge driver connection?

I'm trying to use a JDBC-ODBC bridge driver but I don't know what is the URL I need to put inside a the "getConnection (String URL, String userid, String passwd)" method.
Connection conn = DriverManager.getConnection(URL, user, passwd);
Can anybody help me?

Yes Marc,
but maybe Edgar should know that he first has to add a ODBC datasource.
in WINNT
Goto System ODBC Datasources and try to connect to your DB.
If the test is working than you can use the name you have chosen
as URL
good luck
