Question

在JSP文件中定义：

    <sql:setDataSource      
     driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"
     url="jdbc:microsoft.sqlserver://localhost:1433;databaseName=GP"         
     user="sa" 
     password="sa123"
     var="dSource"/>   

    <sql:query dataSource="dSource" var="result">
         SELECT * FROM GP.FE_ENROLL_DATA 
    </sql:query>

堆栈跟踪：

javax.servlet.jsp.JspException: Unable to get connection, DataSource 
invalid: "java.sql.SQLException: No suitable driver found for dSource" at

Answer 1

您的连接网址是

url="jdbc:microsoft.sqlserver://localhost:1433;databaseName=GP"

据我所知，您的网址为should be either

url="jdbc:microsoft:sqlserver://localhost:1433;databaseName=GP"

表示SQL Server 2000.请注意:而不是.。它可以替代地具有形式

jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]

for SQL Server 2012

Answer 2

您的连接网址是：

url="jdbc:microsoft.sqlserver://localhost:1433;databaseName=GP"

将其替换为以下网址：

url="jdbc:sqlserver://localhost:1433;databaseName=GP"

或：

url="jdbc:microsoft:sqlserver://localhost:1433;databaseName=GP"
