java.lang.ClassNotFoundException: org.postgresql.Driver
(2 answers)
Closed 9 years ago.
I'm making a simple JDBC program in java SE 7 but after compiling program it's giving "java.lang.ClassNotFoundException: org.postgreasql.Driver" error i followed this link http://docs.oracle.com/javase/7/docs/technotes/guides/jdbc/ but not getting yet so please help.
possibly you may not be setting the path of jdbc driver
follow the steps
Right click on your project
click buildpath->configure Build Path
click libraries tab
Click add external jars and give the path of driver
This:
org.postgreasql.Driver
should likely be
org.postgresql.Driver
THe name of the driver is wrong also. Should be org.postgresql.Driver iso org.postgreasql.Driver. So maybe a typo in your java code where you do Class.forname()
You would have to add the JAR file to your classpath for org.postgresql.Driver, You can download it from HERE .
You have to add the jdbc jar file on your build path. Firstly you have to download the jar from the link you provided. Then add it to build path.
If you use eclipse: Right click on your project at the package explorer->Configure Build Path->Libraries->Add external jar->select your jar.
Please check your connection String url or connection driver and run code.

I'm trying to make a program in intelJ that connects to a SQL database, but I receive this error when it tries to find the drivers.
java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
I've checked that the directory I use is correct when using Class.forname
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
and it points to the correct location within the Jar file for the driver. I'd assume that that java is unable to find the class for whatever reason, as I've done the exact same thing with a second project which works fine. Any ideas?
You need to add the driver JAR to the classpath of the project.
If you're using a simple Java project: right click on the project in IntelliJ IDEA > Open Module Settings. Then, Project Settings > Libraries. Click on +. Select Java. Browse to the driver JAR. Click OK and it should work.
You need to add it to the module's dependencies. The Libraries section just lists the libraries of this project.

The infamous java.sql.SQLException: No suitable driver found
(21 answers)
Closed 7 years ago.
I am trying to create a connection to my database(oracle), when I put test my code using the main method, it works seamlessly.
However, when trying to access it through Tomcat 8, it fails with error:
No suitable driver found for "jdbc:oracle:thin:#localhost:1522:xe"
I have added ojdbc6 jar file to lib and also configured the built path.
The url,use, password is correct still it give the above error.
when i paste the same code in main it runs but in tomcat it doesn't.
Put the ojdbc6.jar file in tomcat/lib folder or in your application lib <Aplication>/WEB-INF/lib to get it work.

Connect Java to a MySQL database
(14 answers)
Closed 7 years ago.
I have the same problem that but it is Ubuntu 14.04. I tried to execute a web page with the help of JSP & mysql as a database. After execution in tomcat logs it gives the error of
"java.lang.classNotFoundException:com.mysql.jdbc.driver"
The hint that I got is that I have to keep my mysql-connector.jar file somewhere such that my tomcat will able to access it.
Your Driver class name need to be capitalized. Use like
com.mysql.jdbc.Driver
instead of
com.mysql.jdbc.driver
You can Use Driver instead of driver
or
If you get this error when you are running it, then probably its because you have not included mysql-connector JAR file to your webserver's lib folder. you can Easily Check on Class Path as well . may be jar File Broken . Right Click the project -- > build path -- > configure build path
Thanks
I have java code which connects to a MS-SQL database and procures some data.
Before running the code I set the class path in the Unix Server and it used to work fine.
But for some reason the same jar file which was working a few days back is throwing a Class not found exception java.lang.ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver
I have un-jared the jar file and found that the driver class which I'm loading :
Class.forName("net.sourceforge.jtds.jdbc.Driver");
is present in the specified package structure.
I don't understand how this is happening.
Can anyone suggest any tips to resolve this.
The issue of java.lang.ClassNotFoundException might be the outcome of several reasons:
Jar file is not available in class path. (This is not your case. as
you have mentioned).
Your jar file is corrupted.
Your environment variable value is not accessible by current user.
(Permission revoked by administrator).
Current user don't have permission to read jar file.
Please verify the last three options.
Right button on project-> Properties - > Java built Path -> Order and Export -> And check checkBox with you jar.
If you connect on Android project to Use 1.2.7 version.
I know it's late, but for others facing the same problem..
If you are using eclipse:
1. Go to Project -> Properties -> Java Build Path -> Order and export.. and check the jar file for jtds.version.jar
2. Go to Run Configurations and add this jar file to the user defined jars.
Hope this helps..:)

com.mysql.jdbc.Driver not found with mysql connector in buildpath
I'm working on connecting MySQL database to a Java program. When I run my program I am getting this error
Class Not Found Exception: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
for this line
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
So, what's the problem? I'm placing the connector in the project's file.. Is the correct or should it be in another location?
OS Windows XP, Eclipse 4.0, mysql connector 5.1.22
JAR file need to add to project class path.
First Right click on you Eclipse Project, Project --> Build Path --> Configure Build Path. Under Libraries tab, click Add Jars or "Add External JARs".
You don't even need that line of code, any time in the last five years or so. Just delete it,
The jar file should be in your classpath. If you have created the project through an IDE, make sure you add the jar in your build path.
You have to include the connector jar file in your project's build path. In eclipse project properties dialog, go to "Java Build Path" and add the jar file in "Libraries" tab
the jar should be included in your classpath. In your IDE, configure your build path and add the required jar in your libraries section.
