我正在努力更改 JBoss BRMS 6.4 的默认 H2 数据源以使用 PostgreSQL JDBC 驱动程序。我使用 JBoss EAP 6.4 作为 JBoss BRMS 6.4 的容器。我的 postgresql 驱动程序的名称是：postgresql-9.4-1202.jdbc42.jar 对于新数据库，我安装了 Postgresql 并创建了一个角色和一个数据库，我将其命名为 jbpm。然后我下载了 jboss-brms-bpmsuite-6.4-supplementary-tools/ddl-scripts 用于导入postgresql-jbpm-schema.sql。
以下是我尝试使其工作的方式。
1- 我在standalone.xml 文件中添加了一些新行，以使 JBoss 使用 PostgresSQL 作为数据源：
<system-properties>
<property name="org.kie.example" value="true"/>
<property name="org.jbpm.designer.perspective" value="ruleflow"/>
<property name="designerdataobjects" value="false"/>
<property name="org.jbpm.server.ext.disabled" value="true"/>
<property name="org.jbpm.ui.server.ext.disabled" value="true"/>
<property name="org.uberfire.nio.git.daemon.host" value="0.0.0.0"/>
<property name="org.uberfire.nio.git.ssh.host" value="0.0.0.0"/>
<property name="org.kie.server.location" value="http://orc-brms3:8080/kie-server/services/rest/server"/>
<property name="org.kie.server.controller" value="http://orc-brms3:8080/business-central/rest/controller"/>
<property name="org.kie.server.controller.user" value="brms"/>
<property name="org.kie.server.controller.pwd" value="P@ssw0rd"/>
<property name="org.kie.server.user" value="brms"/>
<property name="org.kie.server.pwd" value="P@ssw0rd"/>
<property name="org.kie.server.id" value="default-kieserver"/>
<property name="jboss.as.management.blocking.timeout" value="700"/>
<property name="org.kie.server.persistence.ds" value="java:jboss/datasources/PostgresqlDS"/>
<property name="org.kie.server.persistence.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
</system-properties>
<subsystem xmlns="urn:jboss:domain:datasources:1.2">
<datasources>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="false" use-java-context="true">
<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
<driver>h2</driver>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
</datasource>
<datasource jndi-name="java:jboss/datasources/PostgresqlDS" pool-name="PostgresqlDS" enabled="true">
<connection-url>jdbc:postgresql://192.168.56.16:5432/jbpm</connection-url>
<driver>postgresql-9.4-1202.jdbc42.jar</driver>
<security>
<user-name>jbpm</user-name>
<password>jbpm</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="postgres" module="org.postgres">
<driver-class>org.postgresql.Driver</driver-class>
</driver>
</drivers>
</datasources>
2-这是我在此路径 /EAP_HOME/modules/org/postgres/main/module.xml 中创建的 module.xml 的内容
<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="org.postgres">
<resources>
<resource-root path="postgresql-9.4-1202.jdbc42.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
3-为了注册业务中心，我还通过添加以下行来配置 persistence.xml：
<jta-data-source>java:jboss/datasources/PostgresqlDS</jta-
data-source>
<property name="hibernate.dialect"
value="org.hibernate.dialect.PostgreSQLDialect" />
4 - 但是当我执行 ./standalone.sh 脚本时，我收到此错误：
00:28:36,709 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) JBAS014612: Operation ("add") failed - address: ([

]}

谢谢你的时间和帮助我，特别是你的时间。
