It looks like you are trying to use a MySQL database named 'database'.  Is that truly the name of your database ?
Did you create your database tables as InnoDB tables ?  Unless you intend to not use transactions with hibernate, you will want to use InnoDB and that changes your database type from MYSQL5 to MYSQL5_INNODB.  Your hibernate dialect also must reflect InnoDB tables.
Finally, your datasource seems unusual: the driver element looks like part of the jar file name rather than a java class name.

My examples below are using jboss 7.1.1 so the dataSource name conforms to JEE6 JNDI conventions...Wildfly may use different conventions.
Also, my example datasource file (par-ds.xml) may require changes for Wildfly.  These steps have been tested with forge 2.10.1.Final.

These are the steps I follow to generate entities for all the tables in my 'par' database:

1. Create a new project named 'par':
project-new --named par --topLevelPackage ca.gerrymatte.par --type war --finalName par ; 

2. Install the jpa plug-in and specify in the persistence.xml that a datasource named parDS will be available when jboss/wildfly starts the webapp:
jpa-setup --provider Hibernate --dbType MYSQL5_INNODB --container JBOSS_AS7 --dataSourceName java:jboss/datasources/parDS;

3. I choose to create a named connection so that I can be sure the database par is accessible from forge:
connection-create-profile - --name parConnection --hibernateDialect org.hibernate.dialect.MySQL5InnoDBDialect --driverClass com.mysql.jdbc.Driver --driverLocation C:/s/jclasses/drivers/mysql.jar --userName root --userPassword xxxx --jdbcUrl jdbc:mysql:///par?characterEncoding=UTF-8&characterSetResults=UTF-8&autoReconnect=true&zeroDateTimeBehavior=convertToNull --verifyConnection true;

4. Generate JPA Entities for all tables using the connection profile:
jpa-generate-entities-from-tables - --databaseTables * --connectionProfile parConnection --targetPackage ca.gerrymatte.par.model ;

My par-ds.xml file contains:
<?xml version="1.0" encoding="UTF-8"?>
<datasources xmlns="http://www.jboss.org/ironjacamar/schema">

                <datasource jta="true" jndi-name="java:jboss/datasources/parDS" pool-name="parDS" enabled="true" use-java-context="true" use-ccm="true">
