Oracle RDB Driver fails with JDBC/ODBC Bridge

Has anyone experienced problems using the latest Oracle RDB
Driver (3.0.2.0) with the JDBC/ODBC Bridge.
We have been using the Oracle ODBC Driver for RDB (2.10.17)
successfully on NT, but it is not supported on W2K. The new
drivers work fine for Access etc., but fail with the bridge.
Specifically, you can step thru a result set, but getObject()
returns null for all fields.
Any suggestions?

Create toplink ofline db objects fails over jdbc-odbc bridge to MSAccess db

Hi, using JDev 10.1.3.0.4 in an EJB , Toplink, JSF application I cannot create Toplink Objects from tables , I get every time a null pointer exception in the last step when I click on the Finalize button.
I have seen other threads the recomend to rebuild the Data Model Project using the Run Menu, that didnt work, Checking unchecking Tools/Preference/Show Compile Progress , didnt help neither.
If the problem is that toplink is incompatible with the jdb-odbc bridge, then where I can get/download a jdbc ms access cappable driver that toplink will work with?
Thanks,
Omar

Look under http://www.oracle.com/technology/products/jdev/htdocs/10.1.3.1/install.html#supported_db to check whether your database is supported (see Offline Database Support column in the table).
Also you can do the following to check whether importing offline tables is causing an issue. See " Importing Tables from a Database Connection" under http://www.oracle.com/technology/obe/obe1013jdev/dbdevelopment/obe_%20dbasedevmt.htm
Hope this helps.

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.

JDBC ODBC bridge (JDK 1.4) exception in native code

I am using jdk 1.4 on windows 98. I have written this simple java program which uses jdbc odbc bridge to connect to an MS Access 2000 db.
An exception in native code is thrown only when I use createStatement with scrollable resultset. If I use createStatement() with default forward only resultset type, then program works.

               Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
               String query = "SELECT * from products";
               ResultSet rs = stmt.executeQuery(query);
               while (rs.next())
                    String s = rs.getString("name");
                    float n = rs.getFloat("price");

Is there any problem with jdbc odbc bridge driver?

No. This is not a bug. Not all databases support (or have to support) all types of resultsets. It is your responsibility to ensure that a particular resultset is supported before you use it. That said, one would definitely expect a more descriptive error message in case of inadvertant use.

Access MS-Access using JDBC ODBC bridge from Sun AMD64

Hi,
We are trying to configure a communication channel using the JDBC adapter. We are setting the driver to the JDBC-ODBC bridge driver and trying to access an MS Acess database from the PI server(sun amd64). When we set the driver to the JDBC-ODBC bridge, the J2EE engine tries to restart immediately and does not start. The std_server.out contains the following error:
Service com.sap.aii.adapter.jdbc.svc started. (234 ms).
1016 sun.io.CharToByteASCII::convert (370 bytes)
1017 ! com.sap.sql.jdbc.common.CommonPreparedStatement::close (119
bytes)
ld.so.1: jlaunch: fatal: relocation error:
file /usr/j2se/jre/lib/amd64/libJdbcO

Has anybody been able to configure the JDBC-ODBC bridge driver for MS Access? Also, has anybody used the database vendor(MS) drivers? If so, where are they available.
Thanks in advance

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 .

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.

JDBC-ODBC Bridge with iAS on UNIX

Can the Sun JDBC-ODBC bridge be used with iAS on UNIX (Solaris)? If possible, can someone share the basic steps. For example, what parameters to enter when configuring the bridge as a datasource and also how to pass needed environment variables (LD_LIBRARY_PATH has to have the path of the ODBC driver manager).
I need to connect to a ODBC driver on UNIX, no JDBC driver is available for this data source, nor is a Windows solution acceptable.
I have iAS 6.0 SP3 with iWS 4.1 SP9 on Solaris 8.

Hi,
I'm not sure if there is a free download available, but you can find some help by visiting the following URL http://www.dbmaker.com/Header/Frame_Forum.htm
For the exact steps, I think this would be more helpful http://www.dbmaker.com/reference/technotes/jdbc.html

JDBC-ODBC Bridge with iAS on Solaris

Is there any way to use the Sun JDBC-ODBC bridge with the iPlanet
Application Server running on UNIX (Solaris)? If it is possible, can
someone who has done it share the basic steps. For example, I cannot
figure out what parameters to enter when configuring the bridge as a
datasource and also how to pass certain environment variables (eg the
LD_LIBRARY_PATH which points to the ODBC driver manager).
It seems that on Windows iAS has ODBC as a Type 2 JDBC data source (at
least the manuals have screenshots with ODBC nodes). However I need to
have iAS running on Solaris (and connecting to a proprietary ODBC
driver; no JDBC driver is available for this data source).
I have iAS 6.0 SP3 with iWS 4.1 SP9 on Solaris 8.
TIA!

JDBC-ODBC BRIDGE "No Suitable Driver"

I am trying to link the JAVA (VJ++) to MS ACCESS 2000. I am always getting the error: "No Suitable Driver"
I am sure I that I have set up the SYSTEM DSN and installed jdk1.2.2 correctly. I just can't understand why it insists on not working!!??
I have tryed everything I know, but I still cant get this problem sorted and I'm about to give up. Does the driver even work when trying to establish this kind of link???!!!
CODE:
public class AuditConnect
     private Connection Aconn;
     private String strUrl = "jdbc:odbc:CSDMATlink";
     private String user = "tiger";
     private String password = "tiger";
     private String Err;
     public AuditConnect()

               catch(ClassNotFoundException ex)
                    Err = ex.getMessage();
               Aconn = DriverManager.getConnection(strUrl, user, password);
          catch(SQLException SQLErr)
               Err = SQLErr.getMessage();
Help me please, I'm desperate!!!

A new version of the JDK was not necessary to fix the problem. In any event let's start with configuring your box correctly. The CLASSPATH environment variable is not necessary when using the core JDK classes (of which the JDBC-ODBC bridge classes are a part of). The CLASSPATH environment variable should only be used if you have third party class libraries you wish to add. I'm assuming that's not the case so I would recommend not coding the CLASSPATH variable. However if you have it already coded make sure to add the current directory (as denoted by a dot). For example:
SET CLASSPATH=.;c:\JDK1.4.1_03\jre\lib\rt.jar
Although the CLASSPATH is not necessary the PATH environment variable is crucial. You need to add the JDK's BIN directory to your current PATH statement. For example:
SET PATH=%PATH%;c:\JDK1.4.1_03\bin
The above should resolve the No suitable driver problem you've been encountering. Since JDK 1.2.x the JDK's CLASSPATH is resolved via the PATH setting.
Now as per my previous post you need to make sure that you really do have a well formed JDBC URL as that can also cause the No suitable driver problem.
I'm not familiar with Win98 so I don't know if you update the environment variables via the AUTOEXEC.BAT file or if you use the Control Panel ala WinNT. Check your documentation to ensure you're updating correctly. Good luck.

Can't find jdbc-odbc bridge driver

Hi
I've installed sdk 2.0 (v1.4.1) and am getting the runtime error:
"Exception in thread main java.lang.NoClassDefFoundError <prog name>/class" from the java prompt.
I suspect it is the jdbc-odbc bridge driver that is the problem. It should have downloaded with the SD 2.0 installation, but I can't find it on my NT PC.
Any ideas?

I suspect you are using,java <program_name>.class to execute your program.
Then it will try to find the promram 'class' in the package '<program_name>'.
You need to use, java <program_name>, thats all.
For eaxample if you have Prg1.java, then use,
'javac Prg1.java' to compile it and 'java Prg1' to run it.

JDBC ODBC Bridge/Driver???

Hi,
Please can someone help me?
I'm a 4th year computer science student and have a final year project to do using databases. My problem is finding a JDBC:ODBC driver/bridge(what's the difference?).Every tutorial on the web says use the
sun.jdbc.odbc.JdbcOdbcDriver, that's all well and good but where do I get it?I've tried downloading JDBC API's but still no joy. When I do finally find a driver do I need to copy it to the folder where the rest of my project is,
(that's what I had to do for a mysql driver I had to use before). I want to use Microsoft Access with the project for portability and ease of alteration, do I need to set up an ODBC driver for my database as well as using the JDBC:ODBC bridge?
That probably came out like complete double dutch but I hope someone out there can make sense of it and help me.

Please can someone help me?Start with a tutorial http://java.sun.com/docs/books/tutorial/jdbc/index.html
Basic info on your particular problem:
JDBC defines an 'interface' that allows one to access databases. That usually consists of serveral parts: the database, the interface layer, the jdbc driver and jdbc itself.
JDBC comes with java. In addition a single jdbc driver, the 'jdbc-odbc bridge' driver comes with java. To use that particular driver you also need the 'interface layer' which for MS Acess will mostly already be available to you - basically the ODBC shell (not part of java) and the MS Access ODBC driver (also not part of java.)
Keep in mind that the jdbc-odbc bridge driver uses the ODBC that is already on the box. ODBC itself is not part of the driver.
You will probably need to configure ODBC for use as a 'DSN' (Data Source Name?). To do that you go to the control panel and use the ODBC (Data Sources) applet. Pick 'System DSN' (a panel in the dialog), push 'Add' and follow the prompts by picking a MS Access driver. You can either use 'create' or 'select' at the end to create or use an existing database.
If this seems like too much work then search the JDBC forum using "DSN-less" as the search string. The discussions there will tell you how to set up a connect string without creating a DSN.

JDBC-ODBC Bridge Driver Suitable?

I'm implementing a web site for a small company, so will be using MS Access for the database.
Will a JDBC-ODBC Bridge driver be suitable?
I ask this as I have heard that JDBC-ODBC Bridge drivers are only suitable for testing purposes - not commercial use.
Cheers

Ideally, you should use a third-party driver in your implementation. Not that there's anything wrong with the JDBC-ODBC Driver, but like you said, Sun never really intended it to be used for mainstream applications. It was developed to serve as a generic driver until third party drivers could be developed and released. Now that there's plenty of good third party drivers out there, the use of the JdbcOdbcDriver is really not recommended. Here's a list of current drivers available for MS Access.

Oracle Rdb Driver 3.1.0.0 problem with blobs

I am trying to convert an MsAccess application to use an MsAccess front end and an Oracle Rdb back end.
I've created the test database under VMS and can successfully link to the Oracle Rdb tables from MSAccess 2000. One of the main reasons for converting to Oracle Rdb is to be able to store large word documents in the database. I was able to do that using Oracle rdb Driver v 3.00.02.06. I recently converted to Oracle Rdb Driver version 3.1.0.0 and can no longer access the Blob field containing the Word document. MsAccess now sees this field as type Binary and I keep getting an invalid field type error. (with 3.00.02.06 this field was seen by MsAccess as an Ole Object and the getchunk and appendchunk functions for getting and saving a blob worked reasonably well).
Is this a bug in 3.1.0.0 or is there some way to get MsAccess to recognize this Binary field type?

I suspect you'll need to contact Oracle support on this. There aren't, to my knowledge, any RDB folks around here.
