Question

部署在另一个系统中的Web应用程序JSF页面没有显示。虽然它在其他系统中工作正常。我在jsf页面中使用了primefaces。

下面的jsf页面在ADD New Data下面有数据表，在提交添加数据时会出现ADD New Data对话框，但它没有显示。

当我从eclipse运行时它工作正常

在tomcat服务器中部署之后，在tomcat访问日志中获取jsf页面的响应代码500。 context.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<Context path="/stc_medical">
<Resource name="jdbc/stc_medical" 
              auth="Container"
              type="javax.sql.DataSource" 
              username="root" 
              password="root"
              driverClassName="com.mysql.jdbc.Driver"
              url="jdbc:mysql://localhost:3306/stc_medical?autoReconnect=true"
              validationQuery="select 1"
              maxActive="10" 
              maxIdle="4"/>
</Context>

ConnectionPool类：

public class ConnectionPool {
    private static ConnectionPool pool = null;
    private static DataSource dataSource = null;

    private ConnectionPool() {
        try {
            InitialContext ic = new InitialContext();
            dataSource = (DataSource) ic
                    .lookup("java:/comp/env/jdbc/stc_medical");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

我在部署war文件时将mysql-connector-java-5.1.23-bin放在tomcat lib目录中，但无法访问数据库。我尝试了很多方法，但无法找到解决方案。

当项目部署在tomcat上时，Mysql数据源无法正常工作
