Java mySQL with 000webhost

Question

Class.for         


        

Answer 1

MySQL from 000webhost doesn't allow you to connect from external applications, just from within pages hosted in their domain.

Answer 2

Please remove the table name from the connection string.

just write

Connection conn = DriverManager.getConnection("jdbc:mysql://mysql2.000webhost.com/a4931569_users", username, pass);

JDBC URL Format

The JDBC URL format for MySQL Connector/J is as follows, with items in square brackets ([, ]) being optional:

jdbc:mysql://[host][,failoverhost...][:port]/[database] »
[?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]...

If the host name is not specified, it defaults to 127.0.0.1. If the port is not specified, it defaults to 3306, the default port number for MySQL servers.

jdbc:mysql://[host:port],[host:port].../[database] »
[?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]...

Here is a sample connection URL:

jdbc:mysql://localhost:3306/sakila?profileSQL=true

Please refer http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-configuration-properties.html

Answer 3

Please make sure that mysql2.000webhost.com URL allows remote connection for the specified user or not. If it allows then there can be some problem with database driver jar file either its missing or not compatible with database version.

Answer 4

As the javadoc for the DriverManager#getConnection() method says:

Attempts to establish a connection to the given database URL.

Therefore, remove the Users table name from the provided URL and it should work.
