Microsoft JDBC Driver - TDS Prelogin Error (?)

Jan 25, 2008

Hi,

Anyone know what I'm doing wrong? My JDBC is erroring. I'm using the Microsoft 1.2 driver, I have a SQL Server 2005 back end with the following clients connecting to it:

ASP.NET 2.0 web application
Visual Studio C# console applications (*2)
Java command line client.

Everything runs hunky-dory on my dev. environment (laptop, local, launched via Visual Studio) but now it's on the server, the Java client is erroring.

When I use the 1.2 sqljdbc.jar file, I get:

25-Jan-2008 12:20:29 com.microsoft.sqlserver.jdbc.SQLServerConnection Prelogin
WARNING: ConnectionID:1 TransactionID:0x0000000000000000 Prelogin response packet not marked as a REPLY

My Error Trap:
--------------
SQL STATE : 08S01
ERROR CODE: 0
MESSAGE : The TDS protocol stream is not valid.

When I use the 1.1 file I get:

My Error Trap:
--------------
SQL STATE : 08S01
ERROR CODE: 0
MESSAGE : The TDS prelogin response is incomplete. The target server must be SQL Server 2000 or later.

I don't know what these errors mean. I've tried compiling as java 1.5 and 1.6 with the same results. It works fine on my laptop (Vista Home Premium) but won't when I try and connect to the server. I've searched the web on the error messages and can't find an answer yet.

Any help appreciated.

My drivers are the Windows versions. Also, everything else is working okay on the server: The consoles are up and running and the web browser connects and SELECTs, UPDATEs & INSERTs okay.
I ought to mention: My laptop is running SQL Server Development edition and the Server is running obviously something else.

My SQL Server version is 9.0.1399 and the OS is Windows Server 2003. SQL Authentication is mixed mode.

Cannot Load JDBC Driver Class 'com.microsoft.jdbc.sqlserver.SQLServerDriver'

Apr 14, 2008

I have read similar posts to this, but I am still having problems.

I am trying to use connection pooling to connect to a local SQL Server 2005 database. I am running my application using
MyEclipse Enterprise Workbench. I have verified that sqljdbc.jar resides in "WebRoot/WEB-INF/lib/"

"WebRoot/WEB-INF/web.xml":
<?xml version="1.0" encoding="UTF-8"?>

<res-ref-name>jdbc/DefaultDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>

</web-app>

"WebRoot/META-INFcontext.xml":

<?xml version="1.0" encoding="UTF-8"?>

validationQuery="select 1"
maxActive="10"
maxIdle="2"/>
</Context>

Classpath:

<classpathentry kind="output" path="WebRoot/WEB-INF/classes"/>
</classpath>

Code to connect:

import java.io.Serializable;
import java.sql.*;

import javax.sql.*;
import javax.naming.*;
public int testConnect(){
Connection conn = null;
InitialContext ctx = null;
java.sql.Statement stmt = null;

try {
ctx = new InitialContext();
Context envCtx = (Context) ctx.lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/DefaultDS");/*This is generating the Cannot load JDBC driver class... error*/
conn = ds.getConnection();
stmt = conn.createStatement();
return CONSTANT.SUCCESS;

} catch (Exception e) {
return CONSTANT.FAILURE;
}finally {
try {
if (stmt != null)
stmt.close();
if (conn != null)
conn.close();
if (ctx != null)
ctx.close();
} catch (Exception ex) {
// do nothing
return CONSTANT.FAILURE;
}
}
}

Any ideas would be greatly appreciated.
