前面已经安装好jbpm了。现在进行数据库的替换。很简单：

1，修改 build.properties

原：

# default is H2

 H2.version=1.3.168

 db.name=h2

 db.driver.jar.name=${db.name}.jar

 db.driver.download.url=http://repo1.maven.org/maven2/com/h2database/h2/${H2.version}/h2-${H2.version}.jar

#mysql

#db.name=mysql

#db.driver.module.prefix=com/mysql

#db.driver.jar.name=mysql-connector-java-5.1.18.jar

#db.driver.download.url=https://repository.jboss.org/nexus/service/local/repositories/central/content/mysql/mysql-connector-java/5.1.18/mysql-connector-java-5.1.18.jar

改：

# default is H2

# H2.version=1.3.168

# db.name=h2

# db.driver.jar.name=${db.name}.jar

# db.driver.download.url=http://repo1.maven.org/maven2/com/h2database/h2/${H2.version}/h2-${H2.version}.jar

#mysql

db.name=mysql

db.driver.module.prefix=com/mysql

db.driver.jar.name=mysql-connector-java-5.1.18.jar

db.driver.download.url=https://repository.jboss.org/nexus/service/local/repositories/central/content/mysql/mysql-connector-java/5.1.18/mysql-connector-java-5.1.18.jar

2.修改db/jbpm-persistence-JPA2.xml:

原：

<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>

改：

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

3，修改standalone-full-wildfly-8.1.0.Final.xml
原：

<datasource jta="true" jndi-name="java:jboss/datasources/jbpmDS" pool-name="H2DS" enabled="true" use-java-context="true" use-ccm="true">

    <connection-url>jdbc:h2:tcp://localhost/~/jbpm-db;MVCC=TRUE</connection-url>

    <driver>h2</driver>

    <security>

       <user-name>sa</user-name>

    </security>

</datasource>

<drivers>

    <driver name="h2" module="com.h2database.h2">

        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>

    </driver>

</drivers>

改：

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

    <connection-url>jdbc:mysql://localhost:3306/jbpm</connection-url>

    <driver>mysql</driver>

    <security>

       <user-name>jbpm</user-name>

       <password>jbpm</password>

    </security>

</datasource>

<driver name="mysql" module="com.mysql">

    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>

</driver>

1，这里要注意红色的字体将原来的替换：

<default-bindings context-service="java:jboss/ee/concurrency/context/default" datasource="java:jboss/datasources/jbpmDS" jms-connection-factory="java:jboss/DefaultJMSConnectionFactory" managed-executor-service="java:jboss/ee/concurrency/executor/default" managed-scheduled-executor-service="java:jboss/ee/concurrency/scheduler/default" managed-thread-factory="java:jboss/ee/concurrency/factory/default"/>
,2，注意。
  db/mysql_module.xml 要与mysql的驱动包名一直如：

<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.18.jar"/>
</resources>

<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>

5，运行ant命令OK
