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 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 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.

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-ODBC Bridge Performance To MS Access

Hey all, I'm running a Java app that extracts an entire table (set of tables) from Oracle and copies them into Access. The easiest implementation has been to use a DSN-less Type 1 JDBC-ODBC bridge connection to Access, but unfortunately the inserts are taking too long.
I have tried both Statement and PreparedStatement approaches, with both single row and batch updates. Some of the performance times, relative to the computer I am on (PIII 1 gHz with 256 RAM), are as follows:
Via Batch, about 8min, 15 seconds per 10,000 rows.
Via Single Row updates/inserts, about 52 minutes for 45,000 rows.
I've tried alot of varieties with batch, but 10,000 seemed to be the best. The largest table is only 45,000 rows (right now), but has the potential to grow much larger (obviously). This application needs to backup 4 databases, each with N tables (current N=7, but will expand). I'm trying to knock down the times and increase performance, but am not sure what is "reasonable" for Type 1 connections with JDBC. I've seen third party drivers, Type 3, for Access...but don't want to run the middle tier server for filtering request through. I'd rather use Type 4, but can't seem to find any for Access.
Any suggestions? Recommendations? Let me know! Thanks all! :)

Hi,
If its a backup/batch process why are you worrying about performance, its only an offline process :) even if has to be triggered during an OLTP run this task asynchronously.
I dont know why you have chosen java to do this ??? any way prepared statements with non scrollable resultsets will increase you performance better tha scrollable normal statements.

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

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 .

JDBC-ODBC Bridge seems to slow down after a while

Hi,
I've got a weird problem going on with an application I'm writing. I hope someone can tell me what I'm doing wrong.
The problem I'm encountering is in he code shown below. The function getAllGamesForATeam is creating a list of items in an ArrayList and passing it back to an Event handler so that I can put it in the session of a servlet. The first time I run this code, it is fast. Fast enough to use on a servlet. The second time it runs, it is MUCH slower...too slow to use on a servlet. The third time it runs, it gets even worse.
I am using the JDBC-ODBC bridge to access my database which is in Access 97. I do have connection pooling enabled on the database. Still it is slow.
If you have any ideas, I would appreciate it. Here's the code:

Where do you close the ResultSet?
Where do you close the Statement?
Presumably you only create one connection for all users or you close it somewhere.

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.

with odbc, we do by "rwrun module=<> userid=<user>/<passwd>@odbc:DSN"
Please specify, what is command line arguments for jdbc-odbc bridge driver?
Environment : Oracle 9i Report Builder on WinNT
Database : Sybase

Hello Ramanan,
Report Builder : connect JDBC Query in Report Builder is to through Connection Dialog in JDBC Query Editor. User can use a Sign on parameter (can use, default : P_JDBCPDS or can create new) to connect to JDBC Data Source. Connection once made will be mentioned and will be reused through out Reports Builder.
JDBC PDS allows user to connect one or more same or different kind of databases.
While running report through runtime or Server, user can pass the sign on parameter(connection string) value, like any other user parameter.
Syntax for connection string : <username>/<password>@databaseURL . The syntax of database part of connection string depend on the type of JDBC Driver used to connect to Data Source while designing the JDBC Query. databaseURL refer to the location of the database and its format depend on the JDBCPDS river selected in design time while creating the JDBC Query.
rwrun eg :
rwrun report=jdbc_odbc.rdf destype=file desname=output.html desformat=html P_JDBCPDS=scott/tiger@database
Server eg :
http://server.com:8888/servlet/RWServlet?server=MyReportServer+report=jdbc_odbc.rdf+destype=cache+desformat=html+P_JDBCPDS=scott/tiger@database

JDBC-ODBC bridge

Hello,
I'm using JDK1.5 and have a working connection to MySQL using JDBC. I now need to connect to Interbase database using ODBC and that's where I'm completely lost.
Could somebody please tell me if I have to download a JDBC-ODBC bridge or if it's already in the package? Can JDBC-ODBC communicate with InterBase?
Please help.
Thank you,
Victor.

Uf you want the password stored in the ODBC DSN, you'll need to go through the back door. This isn't something Oracle makes easy because it has horrible security implications-- the password will be stroed in the registry in plain text.
If you add a key "Password" with the value of your password to the registry where your DSN is, the ODBC driver will use that value to connect to the database. I don't recall the exact heirarchchy riht now, but a registry search for the name of your DSN ought to find it pretty quickly. As always, playing with your registry isn't recommended and may cause problems if you don't do it correctly.

JDBC-ODBC Bridge to SPSS data files - Result Set Type is not supported

Hello,
As mentioned in the subject I am trying to read SPSS data files using the SPSS 32-Bit data driver, ODBC and the JDBC-ODBC Bridge.
Using this SPSS Driver I manged to read the data directly into an MS-SQL Server using:
SELECT [...] FROM
OPENROWSET(''MSDASQL.1'',''DRIVER={SPSS 32-BIT Data Driver (*.sav)};DBQ=' SomePathWhereTheFilesAre';SERVER=NotTheServer'', ''SELECT 'SomeSPSSColumn' FROM "'SomeSPSSFileNameWithoutExt'"'') AS a
This works fine!
Using Access and an ODBC System DNS works for IMPORTING but NOT for LINKING.
It is even possible to read the data using the very slow SPSS API.
However, when it comes to JDBC-ODBC the below code does only work in part. The driver is loaded successfully, but when it comes to transferring data into the resultset object the error
SQLState: null
Result Set Type is not supported
Vendor: 0
occurs.
The official answer from SPSS is to use .Net or to use their implementation with Python in their new version 14.0. But this is obviously not an option when you want to use only Java.
Does anybody have experience with SPSS and JDBC-ODBC??? I have tried the possible ResultSet Types, which I took from:
http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/ad/rjvdsprp.htm
and none of them worked.
Thank you in advance for your ideas and input & stay happy!
Here the code without all the rest of the class arround it:
// Module: SimpleSelect.java

    Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
    DriverManager.setLogStream(System.out);
    // Attempt to connect to a driver. Each one
    // of the registered drivers will be loaded until

    Connection con = DriverManager.getConnection (url);
    // If we were unable to connect, an exception
    // would have been thrown. So, if we get here,
    // we are successfully connected to the URL
    // Check for, and display and warnings generated

    checkForWarning (con.getWarnings ());
    // Get the DatabaseMetaData object and display
    // some information about the connection
    DatabaseMetaData dma = con.getMetaData ();
    System.out.println("\nConnected to " + dma.getURL());
    System.out.println("Driver       " +
      dma.getDriverName());
    System.out.println("Version      " +
      dma.getDriverVersion());
    System.out.println("");
    // Create a Statement object so we can submit
    // SQL statements to the driver
    Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY ,ResultSet.CONCUR_READ_ONLY);
    // Submit a query, creating a ResultSet object
    ResultSet rs = stmt.executeQuery (query);
    // Display all columns and rows from the result set
    dispResultSet (rs);
    // Close the result set
    rs.close();
    // Close the statement
    stmt.close();
    // Close the connection
    con.close();
}

Thank you for your reply StuDerby!
Actually the above script was before, as you suggested, leaving the ResultSetTeype default. This did not work...
I am getting gray hair with SPSS - in terms of connectivity and "integratebility" none of their solutions offered is sufficient from my point of view.
Variable definitions can only be read by the slow API, data can only be read by Python or Microsoft Products... and if you want to combine both you are in big trouble. I can only assume that this is a company strategy to sell their Dimensions Platform to companies versus having companies developping their applications according to business needs.
Thanks again for any furthur suggestions and I hope, that some SPSS Developper will see this post!
Cheers!!

Problem using Jdbc-Odbc Bridge

Hi,
I am using Java 2 SDK and I am trying to access MS Access database on my machine using Jdbc-Odbc bridge. I have set up the DSN in ODBC. But I get the following error when I run my program -
'No Suitable Driver'
Here's my code snippet-
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
String dsn = "jdbc:odbc:DriverInfoDB";
Connection con = DriverManager.getConnection(dsn,"","");
con.setAutoCommit(false);
Statement stmt;
String query = null; // SQL select string
ResultSet rs; // SQL query results
stmt = con.createStatement();
.....etc etc...
Where is the error in this code??
Help Needed!!
Thanks
Vivek.

try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection(dsn,"guest","guest");
OR DriverManager.getConnection(dsn);
System.out.println("Conection's opened");
catch(ClassNotFoundException cnfe)
System.err.println(cnfe);
catch(SQLException sqle)
System.err.println(sqle);
try that code and double check you DSN Name . it's a good practice to greate a system DSN.
i hope that helps.
