Java Against SQL Server
Jul 23, 2005
Anyone have any tips for using Java against SQL Server? Our IT
director is thinking of making us a Java shop, but I really would like
to stay with SQL Server as our RDBMS. We have Oracle Financials but
our in-house development (currently VB6 client-server, soon to be
replaced by a service-oriented architecture based around Sonic and
including SalesForce, both of which are Java) has been against SQL
Server. He says five years ago at his old company Java/SQL Server had
lousy performance. I vaguely remember that since then Microsoft came
out with their own JDBC driver for SQL Server... Anyone have experience
with this? Any performance tips will be hugely appreciated.
TIA

How to connect to the named instance of SQL Server using Java?
I had the following code working fine(but with the default instance only)
SET JAVA_HOME=D:Program FilesJavaSoftJRE1.3.1_03
"D:Program FilesJavaSoftJRE1.3.1_03injava" -classpath Launcher.jar;Sprinta2000.jar;log4j.jar;activation. jar;mail.jar Launcher -Ddatabase -Uuser -Ppassword -Sserver:1433 -hlocalhost -p9900 -TTrue -VFalse -QK -QS
But the same code is failing with the named instance:
SET JAVA_HOME=D:Program FilesJavaSoftJRE1.3.1_03
"D:Program FilesJavaSoftJRE1.3.1_03injava" -classpath Launcher.jar;Sprinta2000.jar;log4j.jar;activation. jar;mail.jar Launcher -Ddatabase -Uuser -Ppassword -Sserverinstance:1434 -hlocalhost -p9900 -TTrue -VFalse -QK -QS

I have a java compiled jar file, which accept the connection string as follows: -Uusername -Ppassword -Sservername:port
This string works fine with the default instance of SQL Server, I mean as long as you supply the name of the SQL Server as 'SQLServer', but if I want to run it against the named instance of SQL Server like 'SQLSERVERNamedInstance' then the connection is failing, giving me the unknown host error. Any idea why?

Hi, guys. It's the first time I connect a database.
My OS is windows XP.
I downloaded the sqljdbc on microsoft website and unzipped it.
Copy the sqljdbc_1.1 to the directory C:Program Files.
Modified the system variables:
classpath=.;%JAVA_HOME%libdt.jar;%JAVA_HOME%lib ools.jar;
%ProgramFiles%sqljdbc_1.1chssqljdbc.jar
JAVA_HOME=D:Program FilesJavajdk1.5.0_10
ProgramFiles=C:Program Files
I installed the sqlserver 2005and created a sqlserver db engine with windows authentification by default.
Using the management studio I created a database named BudgetAuthorization.
After that I created a user:
CREATE LOGIN aaron792 WITH PASSWORD='12345'
USE BudgetAuthorization
CREATE USER aaron792
Now I want to write a java application to access the database.
The application and the database are on the same computer.
I started the TCP/IP service, using the configuration manager.
Then use the eclipse to write the java application:
import java.sql.*;
public class TestJDBC
{
public static void main(String[] srg)
{
String driverName
= "com.microsoft.sqlserver.jdbc.SQLServerDriver"; // Start JDBC
String dbURL = "jdbcqlserver://localhost:1433;
DatabaseName=BudgetAuthorization"; // Connect the server and the database
//String userName = "Administrator"; // windows user
//String userPwd = "password"; // windows login password
String userName="aaron792";
String userPwd="12345";
Connection dbConn;
try
{
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL,userName,userPwd);
System.out.println("Connection Successful!");
// if successful print Connection Successful!
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
But it cann't be done!
The error information is：
Login failed for user 'aaron792'. The user is not associated with a trusted SQL Server connection.
I also tried the windows user, still failed.
What's wrong? Can anyone help?
Many thanks!

As in some of the databases stored procedures can be written in java. Java stored procedures run into inbuilt JVM of database.Does SQL server provides any support for writing stored procedures in java.Is there any inbuilt JVM in SQL server.

Hello, Everybody.
Help me please with one problem which I'm facing with while deploying java server application on my computer (this java app is jBilling). I have configured it as it was said in docs, I have added environment variable CLASPATH as Microsoft documentation said. I'm using SQL Server JDBC driver 1.2 by Microsoft. The result is that I find this message in log file:
2007-05-27 17:21:41,906 WARN [org.jboss.resource.connectionmanager.JBossManagedConnectionPool] Throwable while attempting to get a new connection: null
org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Failed to register driver for: com.microsoft.jdbc.sqlserver.SQLServerDriver; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: com.microsoft.jdbc.sqlserver.SQLServerDriver))
at org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.createManagedConnection(LocalManagedConnectionFactory.java:168)
... and so on.
I have copied sqljdbc.jar to lib folder of the server. That's how I specified connection string:
jdbc:microsoftqlserver://localhost:1434;DatabaseName=Billing;integratedSecurity=false;
Can not think out what to do else. Maybe somebody knows what to do about it?
Many thanks

Hey All,
I am having a problem connecting to a database I have with a java app I am creating for my senior project. I am using the latest MS JDBC for connecting to the SQL Server.
Below is the code I am trying to run:
try {
ds.setIntegratedSecurity(true);
ds.setServerName("localhost\SQLEXPRESS");
ds.setDatabaseName("*databasename*");
con =ds.getConnection();
} catch (Exception ex) {
ex.printStackTrace();
}
The ds and con variables are declared and initialized correctly. The error I am getting now is this:
com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "*databasename*" requested by the login. The login failed.
Any suggestions on what I could be doing wrong?

I've just started getting this EXCEPTION_ACCESS_VIOLATION (0xc0000005) on machines using Windows 2000 sp4 connecting to SQLServer. This is crashing JVMs (multiple Sun versions and BEA also) in the Java VM frame (outside our code). This has just started recently - perhaps with the last set of patches? Has anyone else seen this or know what I could do to get more information? Could this be related to updates to named pipes?
Thanks!

I'm having a problem connecting with a Java application but I CAN connect using my .Net application - the user name and password are the same for both (using the same database on SQL Server Express 2005).
The error I get is: "com.microsoft.sqlserver.jdbc.SQLServerException: Cannot open database "CORNERS" requested by the login. The login failed." An interesing note - I get the same message if the database is not running.
SQL Server Express 2005 is installed in mixed mode.
Here is my connection string in the .Net appplication: <add key="connectString" value="Server=(local);UID=sa;PWD=myPasswd;Database=CORNERS" />.
These are my values in my Java app web.xml -
<init-param>
<param-name>DBDriver</param-name>
<param-value>com.microsoft.sqlserver.jdbc.SQLServerDriver</param-value>
</init-param>
<init-param>
<param-name>DBURL</param-name> <param-value>jdbc:sqlserver://localhostsqlexpress:1055;databaseName=CORNERS</param-value>
</init-param>
<init-param>
<param-name>DBUser</param-name>
<param-value>sa</param-value>
</init-param>
<init-param>
<param-name>DBPwd</param-name>
<param-value>myPasswd</param-value>
</init-param>.
And yes, the port is 1055 - I checked to find it.
I am using Microsoft SQL Server 2005 JDBC Driver 1.0 (sqljdbc_1.0.809.102).
Does anyone have any idea what is wrong so that the login fails in the Java application but works in the .Net application?

My preferred programming language is Java (sorry Microsoft). I've searched for examples of running DMX queries into an Analysis Services database from Java but failed to locate any. I've seen suggestions that XMLA could be used but again, I can't locate any examples (in any language). For my current project I ran up the white flag and used C# instead but this wouldn't be an option in other cases. It would be possible to make the DMX calls from C# objects and call those from Java but that's pretty labourious to code.
Suggestions?

I am in the process of evalulating using SSRS with our Java app and I have a couple questions up front:
I see you can call SSRS thru web services and display an HTML report. Can you have the report go straight to the printer, rather then preview. So we can offer both Print and Print Preview options.
I see the page streaming option. So on page preview we could ask for page 1 to get a snappy display, then ask for the rest of the report to generate in background?
thanks.

Hi.. We have a java application which connect to our MS-SQL DB during midnight using JDBC connector and extract information. But very often ,the java applicatian halted and because of the deadlock as shown below.
Caused by: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Transaction (Process ID 54) was deadlocked o n lock resources with another process and has been chosen as the deadlock victim.
now the java programmer is blaming me that the MS SQL DB is having deadlock and cause their Java application to hang.
Is there any way to clear the deadlock before the the Java applcation run or how to prove the Java application script itself is having problem and causing the deadlock ?

Hello,Does anyone know if SQL Server supports invoking Java methods from aStored Procedure or even a Trigger. For example, it looks like oracleprovides this capability based on the article athttp://www.cs.umbc.edu/help/oracle8...86/04_call2.htm. Itlooks like for a Trigger it uses a SP as an in-between. Any insightinto this would be greatly appreciated.Thanks,--Willard
