尝试使用 MySQL 数据库而不是 H2 来检索进程信息 [在 AS7 中]--jbpm-console 未部署
Trying to use MySQL Database instead of H2 to retrieve Process Info [in AS7]--jbpm-console NOT being deployed
这几天让这个工作变得非常令人沮丧。在尝试重新启动失败的流程时，我无法从保存数据的 H2 表中检索流程实例信息。我决定使用另一个我有权访问的 DBMS--MySQL.
我已经将我的程序包配置为使用 MySQL 数据库而不是默认的内存数据库来记录进程信息数据。我已经按照几个例子来了解我现在所处的位置。我使用的主要文档是

https://developer.jboss.org/wiki/DataSourceConfigurationinAS7#Installing_a_JDBC_driver_as_a_deploymentI
我有
1.) 从 dev.mysql.com 下载 MySQL 驱动程序，并在尝试让它工作几天后意识到它是 JDBC-4 兼容的，它必须是操纵以使其工作
2.) 通过在 jboss/modules/com/mysql/main:
中创建模块文件将驱动程序安装为模块
<module xmlns="urn:jboss:module:1.0" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.35-bin_COMPLIANT.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
3.) 在独立配置中定义了数据源 jboss/standalone/configuration/standalone-full。xml:
<datasources>
<datasource jta="true" jndi-name="java:jboss/datasources/jbpmDS" pool-name="jbpmDS" enabled="true" use-java-context="true" use-ccm="true">
<connection-url>jdbc:mysql://localhost:3306/jbpm6</connection-url>
<driver>mysql</driver>
<security>
<user-name>root</user-name>
<password>pass</password>
</security>
</datasource>
<drivers>
<driver name="mysql" module="com.mysql">
<driver-class>com.mysql.jdbc.Driver</driver-class>
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
5.) JBPM DB 也是使用 jbpm-installer/db/ddl-scripts/mysql 中提供的脚本创建的。所有持久性表似乎都在那里。
我正在使用 . jboss/bin/standalone.sh --server-config=standalone-full.xml&
此安装未成功，我认为此（重复出现的）异常阻止我的 jbpm-console 启动：
