I have 2 applications and 2 databases which are almost the same – both are phonebooks. They are named phonebook and phonebook2, and the databases, phonebookdb and phonebookdb2. I use Spring and Hibernate. What should I configure so that this can work?

I have done this in context.xml:

<Resource name="jdbc/phonebookdb" auth="Container"
        type="javax.sql.DataSource"
        username="root" password=""
        driverClassName="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/phonebookdb?useUnicode=true&amp;characterEncoding=UTF-8"
        maxActive="100" maxIdle="30" maxWait="10000" />
<Resource name="jdbc/phonebookdb2" auth="Container"
        type="javax.sql.DataSource"
        username="root" password=""
        driverClassName="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/phonebookdb2?useUnicode=true&amp;characterEncoding=UTF-8"
        maxActive="100" maxIdle="30" maxWait="10000" />

in server.xml, I have done this:

<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" name="jdbc/phonebookdb" password="" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/phonebookdb?useUnicode=true&amp;characterEncoding=UTF-8" username="root"/>
   <Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" name="jdbc/phonebookdb2" password="" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/phonebookdb2?useUnicode=true&amp;characterEncoding=UTF-8" username="root"/>
   <Realm className="org.apache.catalina.realm.DataSourceRealm" dataSourceName="jdbc/phonebookdb" debug="99" digest="md5" roleNameCol="ROLA" userCredCol="LOZINKA" userNameCol="EMAIL" userRoleTable="phonebook.ROLE" userTable="phonebookdb.KORISNICI"/>
   <Realm className="org.apache.catalina.realm.DataSourceRealm" dataSourceName="jdbc/phonebookdb2" debug="99" digest="md5" roleNameCol="ROLA" userCredCol="LOZINKA" userNameCol="EMAIL" userRoleTable="phonebook2.ROLE" userTable="phonebookdb2.KORISNICI"/>

I have actually made it work, but something with communication with the database is not right. When I try to insert a new user (cro. korisnik) I get this exception:

SEVERE: Cannot add or update a child row: a foreign key constraint fails (`phonebookdb`.`role`, CONSTRAINT `role_ibfk_5` FOREIGN KEY (`ROLA_ID`) REFERENCES `korisnici` (`KORISNIK_ID`) ON DELETE CASCADE ON UPDATE CASCADE)

found the answer.. i didn’t specify mapping in persistant classes that are mapped to database tables.
@Table(name = “phonebookdb.KORISNICI”)
@Table(name = “phonebookdb2.KORISNICI”)
instead of
@Table(name = “KORISNICI”)
@Table(name = “KORISNICI”)
