下面出现“未知错误”如果我尝试使用wildfly-10.1.0.Final Web管理界面创建新的JDBC（数据源） .
> **Unknown error**
>
> Unexpected HTTP response: 500

> Request {

> "jta" => true,
> "enabled" => true,

然后我尝试通过编辑standalone.xml文件手动完成
<datasource jndi-name="java:jboss/datasources/PostgreSQLDS"
pool-name="PostgreSQLDS" enabled="true" use-java-context="true">

通过手动添加，现在WildFly Web管理控制台显示新创建的postgress数据源 . 但是，通过单击WildFLy Web管理控制台中的 Test Connection 按钮，它会弹出以下错误消息：
> Failed to create JDBC connection. An internal error occurred. Details
>
> Unexpected HTTP response: 500

> Request {

> "rolled-back" => true
我已将postgress jdbc驱动程序 postgresql-9.4.1210.jre7.jar 文件复制到：C：\ wildfly-10.1.0.Final \ wildfly-10.1.0.Final \ modules \ system \ layers \ base \ org \ postgresql \ main
和module.xml文件也位于同一目录中，编辑为：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.postgresql">
<resources>
<resource-root path="postgresql-9.4.1210.jre7.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
我的postgrsql数据库名称是 School ，连接限制设置为-1
在使用postgres失败之后我也尝试了mysql但是我从wilefly web界面创建mysql数据源以及手动编辑standalone.xml时得到了完全相同的错误消息 .
mysql驱动程序 "mysql-connector-java-5.1.39-bin.jar" 位于
C：\ wildfly-10.1.0.Final \ wildfly-10.1.0.Final \ modules \ system \ layers \ base \ com \ mysql \ driver \ main
并在同一位置创建module.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.mysql.driver">
<resources>
<resource-root path="mysql-connector-java-5.1.39-bin.jar" />
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
