VersioningError when Using JDBC driver for SQL Server with RMI

Hi,
I wrote a simple class for inserting rows into a database. The database is SQL Server 2000, and I am using weblogic's mssqlserver4 driver. The class works fine, but when I try to export the class as a remote object (using Sun's RMI implementation, not Weblogic RMI), I get the following error:
Exception in thread "main" weblogic.common.internal.VersioningError: No WebLogic packages defined in CLASSPATH at weblogic.common.internal.VersionInfo.<init>(VersionInfo.java:35) at weblogic.version.<clinit>(version.java:18)
at weblogic.jdbc.common.internal.FileProxy.initFileHandles(FileProxy.java:30) at weblogic.jdbc.mssqlserver4.BaseConnection.prepareConnection(BaseConnection.java:215)
at weblogic.jdbc.mssqlserver4.Driver.newConnection(Driver.java:34) at weblogic.jdbc.mssqlserver4.ConnectDriver.connect(ConnectDriver.java:151) at java.sql.DriverManager.getConnection(DriverManager.java:512) at java.sql.DriverManager.getConnection(DriverManager.java:171)
Can anyone tell me why this happens? What is difference between using the driver standalone and using it with RMI? Does it have anything to do with the fact that I'm using Javasoft RMI and not Weblogic RMI? I'm pretty sure I have the classpaths set up correctly.
Thanks,
Bo

Thanks,
BoHi. Show me the whole stacktrace of the exception. The issue seems to be the driver licensing
code, which is looking for the bea.license file, and not finding it. Have your code run a System command
to find and print out the classpath it thinks is in effect. You will then see if the license file is there.

Using JSP & JDBC driver for SQL Server 2000 on Red Hat

I successfully have a .jsp app running on windows server 2000 using JDBC
driver for SQL Server 2000. Which I installed in order to the following
Red Hat:
http://msdn.microsoft.com/MSDN-FILES/027/001/779/install.htm
I moved the .jsp app over to the Red Hat 9 server running Tomcat, while
keeping the MS SQL 2000 on windows. The issue I have is setting up the
JDBC driver for SQL Server 2000 on the Red Hat server.
I created a folder called /usr/java/MSSQLdriver and unzipped the tar file with
the driver for SQL Server 2000. And ran the install.ksh script.
The /usr/java/MSSQLdriver/lib has the following files within it:
msbase.jar, msutil.jar, & mssqlserver.jar
I chmod 0777 each of the *.jar files.
I then went into /etc/profile.d/tomcat.sh and adding the following:
CLASSPATH=.;/opt/msSQLjdbc/lib/msbase.jar;/opt/msSQLjdbc/lib/msutil.jar;/opt/msSQLjdbc/lib/mssqlserver.jar
Each time I login and pull up the termial I get the following error:
bash: /opt/msSQLjdbc/lib/msbase.jar: cannot execute binary file
bash: /opt/msSQLjdbc/lib/msutil.jar: cannot execute binary file
bash: /opt/msSQLjdbc/lib/mssqlserver.jar: cannot execute binary file
And can't connnect to the database within the .jsp app.
Is there anyone out there using DBC driver for SQL Server 2000 on the Red Hat server?
Michael

Sorry, I needed to correct some information of where the drivers were installed.
I created a folder called /usr/java/MSSQLdriver/new and untar the Microsoft file with the driver for SQL Server 2000. I ran the install.ksh script "sh install.ksh"
installed the driver into the default directory "/opt/msSQLjdbc".
The /opt/msSQLjdbc/lib has the following files within it:
msbase.jar, msutil.jar, & mssqlserver.jar

JDBC driver for SQL Server 2000 with windows authentication

Does anyone know of a JDBC driver for SQL Server 2000 that supports Windows Authentication, that is that a username and password does not need to be supplied when connecting to the database.

You can use the JDBC-ODBC-Bridge.
ODBC provides windows-authentication.
Hope it helps.

JDBC Driver for SQL Server 7

Is there a free JDBC Driver for SQL Server 7 available? If so, where? I created a server program that listens to a port and inserts records based on information it receives. It uses sun's JDBC:ODBC Bridge but it crashes randomly (sometimes weeks, sometimes days, sometimes hours after starting program). Each time it crashes it generates a error log file like this:

Error deploying JDBC driver for SQL Server 2005

Hi all
I'm trying to deploy a JDBC driver for MS SQL Server 2005 (downloaded [here|http://www.microsoft.com/downloads/details.aspx?familyid=C47053EB-3B64-4794-950D-81E1EC91C1BA&displaylang=en]). When I try to deploy it according to the instructions found [here|http://help.sap.com/saphelp_nwce10/helpdata/en/51/735d4217139041e10000000a1550b0/frameset.htm] it fails.
The error in the logs doesn't give any useful information though. It only says Error occurred while deploying component ".\temp\dbpool\MSSQL2005.sda".
Has anyone else deployed a driver for SQL Server 2005, or perhaps have any suggestions of what else I could try?
Thanks
Stuart

Hi Vladimir
That's excellent news! Thanks for the effort you've put into this. I'm very impressed with how seriously these issues are dealt with, specifically within the Java EE aspects of SAP.
May I make two suggestions on this topic:
1. Given that NWA has such granular security permissions, please could the security error be shown when it is raised? This would help immediately identify that the problem isn't actually a product error, but rather a missing security permission (and thus save us time and reduce your support calls).
2. Please could the role permissions be clearly documented (perhaps they already are, and I just couldn't find the docs?) so we know what is and isn't included in the role. The name is very misleading, as a "superadmin" is generally understood to have no limitation on their rights - so clear documentation on what is in-/excluded would be most helpful.
On a related topic, I came across another issue like this that may warrant your attention (while you're already looking into NWA security issues). I logged a support query about it (ref: 0120025231 0000753421 2008) in case you can retrieve details there (screenshots, logs, etc.). It's basically a similar security constraint when trying to create a Destination. I'm not sure if this is something you would like to include as standard permissions within the NWA_SUPERADMIN role or not, but I think it's worth consideration.
Thanks again for your help!
Cheers
Stuart

How do I install the jdbc driver for sql server 2005, in sql developer 4.0 ?

Hallo together
I need access to tables in a MS SQL Server 2005 database.
One possibility is the JDBC driver.
How do i install this driver ?
Thank you very much for your postings.

Hi,
This is from the documentation -
Database: Third Party JDBC Drivers
The Third Party JDBC Drivers pane specifies drivers to be used for connections to third-party (non-Oracle) databases, such as IBM DB2, MySQL, Microsoft SQL Server, or Sybase Adaptive Server. (You do not need to add a driver for connections to Microsoft Access databases.) To add a driver, click Add Entry and select the path for the driver:
For Microsoft SQL Server or Sybase Adaptive Server: jtds-1.2.jar, which is included in the jtds-1.2-dist.zip download
To find a specific third-party JDBC driver, see the appropriate website (for example, http://www.mysql.com for the MySQL Connector/J JDBC driver for MySQL, http://jtds.sourceforge.net/ for the jTDS driver for Microsoft SQL Server and Sybase Adaptive Server, or search at http://www.teradata.com/ for the JDBC driver for Teradata). For MySQL, use the MySQL 5.0 driver, not 5.1 or later, with SQL Developer release 1.5.
You must specify a third-party JDBC driver or install a driver using the Check for Updates feature before you can create a database connection to a third-party database of that associated type. (See the tabs for creating connections to third-party databases in the Create/Edit/Select Database Connection dialog box.)
Alternative:
As an alternative to using this preference, you can click Help, then Check for Updates to install the JTDS JDBC Driver for Microsoft SQL Server and the MySQL JDBE Driver as extensions.
Regards,
Mike

Test JDBC Driver For SQL Server 2000 Failed

Hi:
I have trouble setting up the database connection using jdbc driver in the studio, could anyone help me please? I have MS SQL 2000 MSDE installed on my local machine. I downloaded and installed the JDBC Driver for MSSQL 2000 from Microsoft.
I put the following jar files into the/lib/ext/ directory
msbase.jar
mssqlserver.jar
msutil.jar
In Studio 4.1 EE, I went to Runtime>Databases>Drivers, Add a new Driver with these information:
Name: MSSQL Driver
Driver: com.microsoft.jdbcx.sqlserver.SQLServerDataSource
URL Prefix: jdbc:microsoft:sqlserver://localhost:<PORT>[;DatabaseName=<DB>]
Next I run the Test Driver...
Database URL: jdbc:microsoft:sqlserver://<machineName>\\<instanceName>;DatabaseName=<xxx>
User: <username>
Password: <password>
I receieved the a popup box and message in the output window:
Internal test driver incomplete. the driver may not support the required DatabaseMetadata methods. take a look at the Output Window for details.
Warning: No tables were found. Check your database.
Warning: No views were found. Check your database

com.microsoft.jdbcx.sqlserver.SQLServerDataSource is a very old direct driver. I'd recommend using the DataDirect 3.2 driver. It can be found at:

Porblem loading Microsoft JDBC Driver for SQL Server

Hi all !!
Well, it seems there is a naming problem for the MS Driver, when Netbeans creates server resources for the Connection Pool and the DataSource, the default name for the connection pool's datasource classname is com.microsoft.jdbc.sqlserver.SQLServerDataSource, but the actual name of the class within the driver's jar is com.microsoft.jdbcx.sqlserver.SQLServerDataSource, note the 'x' after jdbc.
I changed this and the resource is created correctly (from the admin console, it pings to the DB server), but when I try to deploy the project, I get this error:
RAR5038:Unexpected exception while creating resource
RAR5117 : Failed to obtain/create connection. Reason : Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource
RAR5114 : Error allocating connection : [Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource]
WebModule[WebApplication2]java.sql.SQLException: Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource
java.lang.RuntimeException: java.sql.SQLException: Error in allocating a connection. Cause: Class name is wrong or classpath is not set for : com.microsoft.jdbc.sqlserver.SQLServerDataSource
I guess I must change the name of the classname in some other place, but I searched the admin colsole and Netbeans and failed to find where it should be.
I'm using Netbeans 5.5 and SQL Server 200 with the MS JDBC Driver sp 3.
Thanks in advance,
Daniel

Thanks for your answer !!
Yes, the datasource classname is correct in domains.xml.
I had the driver files copied into Appserver/lib, now I placed them also where you suggested me and restarted the server.
Now I get a different error:

I guess it may have something to do with any of the classpathes, there is a system or environment CP, one for the App server (with prefixes, suffixes, etc, and there is another in the Netbeans IDE tools Options....
I also tried to debug into java.io.WinNTFileSystem.canonicalize0(Native Method) just to see the name of the file who raised the exception, but I couldn't attach the BPEL debugger, it gives me this error:
11:57:24 Connecting to localhost:3343
11:57:24 Unable to start a debug session : Unable to connect to localhost:3343 : Connection refused: connect
I'm using a proxy but the system settings are set to not use the proxy for localhost addresses and so is netbeans.
How much I miss the simplicity of the old Turbo Pascal days !!
Thanks for your help !!
