java - connecting to a database through JDBC -

-

this question has answer here:

i trying follow tutorial in book on connecting program database jdbc. confused on first block of code doing in class. whan run code error saying java.sql.sqlexception: no suitable driver found jdbc:mysql://localhost:8889/book_store

and code throwing exception in first block inside class. need add sort of dependency or library project?

as can tell first attempt @ using db...

package com.apress.books.dao;  import com.apress.books.model.author; import com.apress.books.model.book; import com.apress.books.model.category;  import java.sql.*; import java.util.arraylist; import java.util.list;  public class bookdaoimpl implements bookdao {  static {     try {         class.forname("com.mysql.jdbc.driver");     } catch (classnotfoundexception ex) {     } }  private connection getconnection() throws sqlexception {     return drivermanager.getconnection("jdbc:mysql://localhost:8889/book_store",             "root", "password"); }  private void closeconnection(connection connection) {     if (connection == null)         return; try {         connection.close();     } catch (sqlexception ex) {     } } @override public void insert(book book) {  }  @override public void update(book book) {  }  @override public void delete(long bookid) {  } }

in essence classnotfoundexception. first catch clause empty , thus, although exception being caught, not acting upon it. in least, this:

static {     try {         class.forname("com.mysql.jdbc.driver");     } catch (classnotfoundexception ex) {         throw ex;     } }

this see better causing troubles.

moving on solution:

if using maven, need add following dependency in pom.xml:

<dependency>     <groupid>mysql</groupid>     <artifactid>mysql-connector-java</artifactid>     <version>5.1.35</version> </dependency>

and if want, change version 1 found here.

otherwise, need download jar same link , include in project dependencies.
