问题
I'm trying to connect Oracle database using this tutorial. It is working when I use command line: java -cp c:\jdbc-test\ojdbc6.jar;c:\jdbc-test OracleJDBC I have put ojdbc6.jar in the same folder with OracleJDBC.java. Now I need to run it on Eclipse, but it gives me an error:
Output: *Where is your Oracle JDBC Driver?
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:190) at OracleJDBC.main(OracleJDBC.java:32)*
Is it because of ojdbc6.jar location?
回答1:
Add the library in the project build path.
- Right click on project
- Build Path
- Go to Libraries Tab
- Add external jar (ODBC jar) there
回答2:
You just need to add ojdbc6.jar into classpath of your application.
回答3:
you need to keep the jar file in external library follow this way
- right click on your project
- click "build path"
- click "configure build path"
- click "library " tab
- click "add external jars"
- give the path of the jar file
Then run it Please see the screenshots
