SQLException: this driver is not configured for integrated authentication tomcat

Am trying to connect MS SQL server through java web applications.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
connection= DriverManager.getConnection("jdbc:sqlserver://localhost;databaseName=XXX;integratedSecurity=true");
I have copied "sqljdbc_auth.dll" to $Tomcat_home/bin and copied jar into $Tomcat_home/lib folder.
I Have multiple web apps in same tomcat instance.
The first webApp loads and successfully establishes the connection with MS SQL.
But the remaining apps fail to connect to MS SQL prompting:
com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication. ClientConnectionId:41d72756-1383-427e-8c4f-c3075ae1559a
at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:2400)
at com.microsoft.sqlserver.jdbc.AuthenticationJNI.<init>(AuthenticationJNI.java:68)
at com.microsoft.sqlserver.jdbc.SQLServerConnection.logon(SQLServerConnection.java:3132)
at com.microsoft.sqlserver.jdbc.SQLServerConnection.access$100(SQLServerConnection.java:43)
Note: Tomcat runs as windows service. And MSSQL is configured to windows authentication.
edit:
I understand that the native library (DLL) can only be loaded into the JVM once, hence the error, but I after looking around the net I still have no solution.

sqljdbc_auth.dll is need to use windows authentication or Kerberos authentication.
Get the dll from Microsoft and install it either by:
drop on application library folder
drop on the java bin folder.
Not recommended if you want to package the applications with all the
dependencies. Also, it requires to find what java version is being
used and from what path.
drop the library on some folder and then add the path in the command line:
java -Djava.library.path=<library path>...
The mssql-jdbc driver and the sqljdbc_auth.dll should be:
on the same folder
both from the same version
for the same architecture (x86/x64) JVM is running.
Check also the jdbc comparability matrix with java versions.

The JDBC driver supports the use of Type 2 integrated authentication on Windows operating systems through the integratedSecurity connection string property. To use integrated authentication, copy the sqljdbc_auth.dll file to a directory on the Windows system path on the computer where the JDBC driver is installed.
Alternatively you can set the java.libary.path system property to specify the directory of the sqljdbc_auth.dll. For example, if the JDBC driver is installed in the default directory, you can specify the location of the DLL by using the following virtual machine (VM) argument when the Java application is started:
-Djava.library.path=c:/sqljdbc_<version>/enu/auth/x86
or
-Djava.library.path=c:/sqljdbc_<version>/enu/auth/x64
Please read more about in the original documentation:
https://learn.microsoft.com/en-us/sql/connect/jdbc/building-the-connection-url?view=sql-server-2017

In order to be able to connect with the JDBC, you need to define the connection as follows:
"jdbc:sqlserver://*******
;authenticationScheme=NTLM;integratedSecurity=true;domain=******
****;databasename=**********;encrypt =
true;trustServerCertificate=true;user=*******;password=*******;"
Use the following dependency:
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>10.2.0.jre8</version>
</dependency>

No suitable driver when trying to create SQL database [duplicate]

This question already has answers here:
SQLException: No suitable driver found for jdbc:derby://localhost:1527
(19 answers)
Closed 7 years ago.
I am trying to create a new SQL database with this Java program
import java.sql.*; //Needed for JDBC classes
public class BuildPhonebookDB {
public static void main(String[] args) throws Exception{
//Create a named constant for the URL
final String DB_URL = "jdbc:derby:Phonebook;create=true";
try {
//Create a connection to the database.
Connection conn = DriverManager.getConnection(DB_URL);
//Create a Statement object.
Statement stmt = conn.createStatement();
//Create the Entries table
stmt.execute("CREATE TABLE Entries (" +
"Name CHAR(20)"+
"Number INTEGER)"
);
System.out.println("Database Connected");
//Close the connection
conn.close();
}
catch(Exception ex) {
System.out.println(ex.getMessage());
}
}
}
When I try to run the program I get an error that:
No suitable driver found for jdbc:derby:Phonebook;create=true
I have looked at various other similar posts on Stack Overflow, such as this one, but none help. I have seen things about a driver jar, but I don't know what this is, if I need to edit this, could someone help me through it?
Thanks for any help

Did you see this guide and have you complited all step of this guide?
Apache Derby
Download Derby Download the binary Apache Derby distribution from the
Derby web site at http://db.apache.org/derby/derby_downloads.html.
These tutorial instructions use version 10.12.1.1 and assume you
downloaded one of the binary distribution files listed in the table
below:
Operating System Download File Windows db-derby-10.12.1.1-bin.zip
UNIX, Linux, and Mac db-derby-10.12.1.1-bin.tar.gz If a more recent
release is available, download that, then substitute that version
number for 10.12.1.1 in the following instructions.
Install Derby Choose the directory into which you want to install the
Derby software. You must have write permissions to this directory. The
sample instructions below use C:\Apache for Windows and /opt/Apache
for UNIX; be sure to use your actual location. Copy the software
distribution to the location you choose, then extract it as shown
below.
Windows (use your extraction tool e.g. WinZip -- these instructions
use mks unzip):
mkdir C:\Apache copy db-derby-10.12.1.1-bin.zip
> C:\Apache cd C:\Apache unzip db-derby-10.12.1.1-bin.zip
UNIX:
mkdir /opt/Apache cp db-derby-10.12.1.1-bin.tar.gz /opt/Apache
> cd /opt/Apache tar xzvf db-derby-10.12.1.1-bin.tar.gz
In both cases, the software will now be extracted into a subdirectory
named db-derby-10.12.1.1-bin.
Set DERBY_INSTALL Set the DERBY_INSTALL variable to the location where
you installed Derby. Examples are shown below, but be sure to use the
actual location on your system:
Windows: C:\> set DERBY_INSTALL=C:\Apache\db-derby-10.12.1.1-bin
UNIX Korn Shell:
$ export
> DERBY_INSTALL=/opt/Apache/db-derby-10.12.1.1-bin
Configure Embedded Derby To use Derby in its embedded mode set your
CLASSPATH to include the jar files listed below:
derby.jar: contains the Derby engine and the Derby Embedded JDBC
driver derbytools.jar: optional, provides the ij tool that is used by
a couple of sections in this tutorial You can set your CLASSPATH
explicitly with the command shown below:
Windows:
C:\> set
> CLASSPATH=%DERBY_INSTALL%\lib\derby.jar;%DERBY_INSTALL%\lib\derbytools.jar
;.
UNIX:
$ export
> CLASSPATH=$DERBY_INSTALL/lib/derby.jar:$DERBY_INSTALL/lib/derbytools.jar:.
...
Step 3: Embedded Derby
When an application accesses a Derby database using the Embedded Derby
JDBC driver, the Derby engine does not run in a separate process, and
there are no separate database processes to start up and shut down.
Instead, the Derby database engine runs inside the same Java Virtual
Machine (JVM) as the application. So, Derby becomes part of the
application just like any other jar file that the application uses.
Figure 1 depicts this embedded architecture.
Set the environment
To set up the environment, follow the "Configure Embedded Derby"
instructions.

Use this before you get the connection from the driver:
Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();

SQLException: No suitable driver found for jdbc:mysql://localhost:3306/dbname

I've inherited a project (and I have absolutly no experience of Java) and I'm rather stuck.
We have a server running redhat, which I needed to update one of the jar files. So I simply copied up the updated file and restarted the service for that file. However this process has worked on our other server I did that too but on this one it comes up with the below in the log file.
Exception: com.mysql.jdbc.Driver
SQLException: No suitable driver found for jdbc:mysql://localhost:3306/dbanme
The jar files are uploaded to a folder in the root of the website and within that jar folder is a lib folder where mysql-connector-java-5.1.6-bin.jar is located.
Does anyone know what I could be missing as I'm a newbie to linux aswell.
Thanks in advance

java.sql.SQLException: No suitable driver found
This exception can have 2 causes:
The JDBC driver is not loaded at all.
URL does not match any of the loaded JDBC drivers.
Since the driver seems to be loaded , it look like that the URL is not valid on that machine:
jdbc:mysql://localhost:3306/dbname
Do you have mysql running and listening on port 3306 on that machine. Also make sure you hte schema dbname there.

You need only set that:
[jdbc:mysql://localhost/dbanme]
instead of
[jdbc:mysql://localhost:3306/dbanme]
Because java compiler default understand a port 3306, so no need to fill "3306" after "localhost:"

Connecting to SQLite Database Fails

I am attempting to access my SQLite3 database in a Java Applet. When I run my code to connect to the database I get this error No suitable driver found for a.db, how can I fix it?
Now I am not entirely sure I have actually installed the correct driver...I will tell you what I have done & could you tell me what else I need to do to make Eclipse IDE find the SQLitejdbc driver:
BK info: On windows 7, using Eclipse Helios Java
I have a SQLite3 database created in python & I want to read it in my Java Applet
I have downloaded the file sqlitejdbc-V056.jar from http://www.zentus.com/sqlitejdbc/
Then I copied & pasted the above file to the paths C:\Program Files\Java\jre6\lib & C:\Program Files\Java\jre6\lib\ext
Run the following code in a Java Applet & get an exception thrown with the text: "No suitable driver found for a.db"
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("a.db"); // exception thrown here
Any information would be really helpful. Do I need to import the driver into my Eclipse project?

Try this:-
Class.forName("org.sqlite.JDBC");
Connection conn = DriverManager.getConnection("jdbc:sqlite:a.db");

JMeter JDBC Response message: java.sql.SQLException: No suitable driver found for jdbc:oracle:

When I connect the database with JDBC i get this:
[StatAggResultCollector] Test Started, host: *local*
[StatAggResultCollector] Test Ended, host: *local*
in response message I get:
java.sql.SQLException: No suitable driver found for jdbc:oracle:..
Any solution?
Is this from jdbc driver or from configuration?

Looks like JMeter cannot find the Oracle driver.
Have you put the ojdbc14.jar or classes12.zip (which contains Oracle drivers) file in the JMETER/lib directory

For Oracle database 9 and 10 use ojdbc14.jar for Oracle database 11 use ojdbc5.jar if you use java 1.5 or ojdbc6.jar if you use java 1.6. Check java version in jmeter.bat file.
