JNDI DB连接从WSO2数据源失败，但在context.xml中工作

wso2

JNDI DB连接从WSO2数据源失败，但在context.xml中工作,wso2,wso2as,Wso2,Wso2as,我正在编写一个小型Web服务，它将数据持久化到数据库中。我正在使用WSO2应用服务器5.2.1和Oracle数据库XE 11g，并在Windows 7上进行开发/测试当我在[AppServerHome]/repository/conf/tomcat/context.xml中创建一个资源时，代码是有效的。相反，当我在管理控制台下创建一个数据源并将其作为JNDI数据源公开时，getConnection调用失败，并出现SQLException 如果我使用管理控制台中创建的数据源通过管理控制台创建数据

我正在编写一个小型Web服务，它将数据持久化到数据库中。我正在使用WSO2应用服务器5.2.1和Oracle数据库XE 11g，并在Windows 7上进行开发/测试

当我在[AppServerHome]/repository/conf/tomcat/context.xml中创建一个资源时，代码是有效的。相反，当我在管理控制台下创建一个数据源并将其作为JNDI数据源公开时，getConnection调用失败，并出现SQLException

如果我使用管理控制台中创建的数据源通过管理控制台创建数据服务，那么数据服务也可以工作。因此，这应该表明数据源是有效的和工作的

我尝试了jdbc url的不同变体：

jdbc:oracle:thin:@localhost:1521:xe jdbc:oracle:thin:@localhost:1521/xe jdbc:oracle:thin:@localhost:1521:XE jdbc:oracle:thin:@localhost:1521/XE jdbc:oracle:thin:@localhost:1521:xe jdbc:oracle:thin:@localhost:1521/xe jdbc:oracle:thin:@localhost:1521:XE jdbc:oracle:thin:@localhost:1521/XE 我也尝试过检查“使用数据源工厂”选项，但并不真正了解它的功能。它也没有明显的效果

我试着按照当时的指示去做，但也没有效果

有人能解释为什么数据源不适用于webapp，而context.xml资源适用于webapp吗？我需要让数据源正常工作，以便在context.xml文件中没有纯文本密码，并且严格通过WSO2管理控制台管理数据源和密码

context.xml中有效的资源是：

<Resource name="jdbc/db1" auth="Container"
     type="javax.sql.DataSource" driverClassName="oracle.jdbc.OracleDriver"
     maxActive="100" maxIdle="30" maxWait="10000"
     url="jdbc:oracle:thin:@localhost:1521:xe"
     username="user" password="aPasswordGoesHere"/>

我在管理控制台下创建的数据源包含以下信息：

Data Source Type: RDBMS Name: MyDB Data Source Provider: default Driver: oracle.jdbc.OracleDriver URL: jdbc:oracle:thin:@localhost:1521:xe Username: user Password: aPasswordGoesHere Expose as a JNDI Data Source: Name: jdbc/db1 Use Data Source Factory: unchecked JNDI Properties: none set Data Source Configuration Parameters: (No changes made) 数据源类型：RDBMS 姓名：MyDB 数据源提供程序：默认值驱动程序：oracle.jdbc.OracleDriver URL:jdbc:oracle:thin:@localhost:1521:xe 用户名：user 密码：ApassWordGoesher 作为JNDI数据源公开：名称：jdbc/db1 使用数据源工厂：未选中 JNDI属性：未设置数据源配置参数：（未作任何更改）以及META-INF/context.xml中的匹配资源链接

<ResourceLink name="jdbc/db1" global="jdbc/db1" type="javax.sql.DataSource" />

用于获取数据源的代码是：

Connection conn; try { DataSource ds; Context ctx; Object obj; ctx = new InitialContext(); obj = ctx.lookup(jndiName); ds = (DataSource) PortableRemoteObject.narrow(obj, DataSource.class); conn = ds.getConnection(); } catch (NamingException e) { throw new DBException("Failed to get data source from JNDI directory: " + e.getMessage(), e); } catch (SQLException e) { throw new DBException("Unable to get connection from connection pool: " + e.getMessage(), e); } 连接接头；尝试 { 数据源ds；上下文ctx；对象对象对象； ctx=新的InitialContext（）； obj=ctx.lookup（jndiName）； ds=（DataSource）PortableRemoteObject.窄带（obj，DataSource.class）； conn=ds.getConnection（）； } 捕获（NamingE例外） { 抛出新的DBException（“未能从JNDI目录获取数据源：”+e.getMessage（），e）； } 捕获（SQLE异常） { 抛出新的DBException（“无法从连接池获取连接：”+e.getMessage（），e）； } 我在wso2carbon.xml中得到的错误是：
