intellij scala java.lang.classnotfoundexception oracle.jdbc.driver.oracledriver

Question

I've this message error when I run my scala code :

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Here my code :

object ScalaJdbcConnectSelect extends App {
  val url = "jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=XXX)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=XXX)(PORT=1521))(FAILOVER=on)(LOAD_BALANCE=on))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XXX)))"
  val driver = "oracle.jdbc.driver.OracleDriver"
  val username = "XXX"
  val password = "XXX"
  var connection:Connection = _
  try {
    Class.forName(driver)
    connection = DriverManager.getConnection(url, username, password)
    val statement = connection.createStatement
    val rs = statement.executeQuery("SELECT * FROM TABLE WHERE ID = 1")
    while (rs.next) {
      val host = rs.getString("ID")
      val user = rs.getString("Field")
      println("ID = %s, Field = %s".format(host,user))
    }
  } catch {
    case e: Exception => e.printStackTrace
  }
  connection.close
}

I download ojdbc6.jar (database oracle version is 11) and in Project Structure > Project Settings > Modules I add my JAR (that appears in Libraries tab) but my error still happen.

I tried to change oracle.jdbc.driver.OracleDriver to oracle.jdbc.OracleDriver but it changes anythings.

I know my database connection's configuration is good because I can connect via DB Browser and test some sql request.

Did I miss something ? I'm new with Scala

Answer 1

I solved my problem !!

Thanks to @Mark Rotteveel for the solution :

If you execute through the terminal, then you are responsible for declaring the classpath for scala (and for scalac for that matter), eg scala -classpath ScalaJdbcConnectSelect

Answer 2

Clearly seems to be a classpath related issue. Usually i'll ask for clarifications with regards to your dependency manaagement but the forum doesn't permit

Try importing oracle.jdbc.driver.OracleDriver to your package
