数据库是mysql
用的是resin3 +myeclipse5.5 +mysql5 是不是有可能是驱动问题
JAVA_HOME=/usr/java/jdk
export JAVA_HOME
PATH=$JAVA_HOME/bin:JAVA_HOME/jre/bin:$PATH
export PATH
CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/dt.jar:JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib:$TOMCAT_HOME/common/lib:$JAVA_HOME/jre/lib/ext/mysql-connector-java-3.1.12-bin.jar
export CLASSPATH
CATALINA_HOME=/opt/tomcat
export CATALINA_HOME
CATALINA_BASE=/opt/tomcat
export CATALINA_BASE
TOMCAT_HOME=/opt/tomcat
export TOMCAT_HOME
将mysql的驱动程序mysql-connector-java-3.1.12-bin.jar放置在Tomcat_home/command/lib目录下。
用一测试文件test.jsp测试能否连接数据库：
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page import="java.sql.*"%>
<html>
<head>
<title>
testmysql
</title>
</head>
<body bgcolor="#ffffff">
<%Class.forName("com.mysql.jdbc.Driver").newInstance();
String url="jdbc:mysql://localhost/test";
String username="lenovo";
String password="lenovo";
Connection conn=DriverManager.getConnection(url,username,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from test";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next())
%>
your first data:<%=rs.getString(1)%>
your second data:<%=rs.getString(2)%>
<%%>
<%out.print("mysql opration is success");%>
<%rs.close();
stmt.close();
conn.close();%>
</body>
</html>
在mysql内建立测测试数据库test，表test
create table test(col1 varchar(10),col2 varchar(10));
insert into test(col1,col2)values(aaa,bbb);
结果jsp访问数据库的时候出现错误：Server configuration denies access to data source.
首先觉得是数据库的用户或者权根不正确。在字符模下mysql -u root -p登录数据库，对其进行管理
输入:
GRANT ALL PRIVILEGES ON *.* TO root@localhost IDENTIFIED BY "password";
FLUSH PRIVILEGES;
测试jsp,还是不行，
通过：telnet localhost 3306，结果出现：
KHost 'localhost.localdomain' is not allown to connect to this mysql serverConnection closed by
foreign host.
于是登入数据库
GRANT ALL PRIVILEGES ON *.* TO root@localhost.localdomain IDENTIFIED BY "password";
FLUSH PRIVILEGES;
之后一切正常
后想起来可能是前面装了weblogic产生的本回答被提问者采纳
以下错误是啥意思：java.sql.sqlexception 在索引处缺少输入或输出参数
【中文标题】以下错误是啥意思：java.sql.sqlexception 在索引处缺少输入或输出参数【英文标题】：what does the following error mean: java.sql.sqlexception missing in or out parameter at index以下错误是什么意思：java.sql.sqlexception 在索引处缺少输入或输出参数 【发布时间】：2011-08-08 02:12:06 【问题描述】：在处理一些 JDBC 代码时出现以下错误：
java.sql.sqlexception missing in or out parameter at index: 6
有人能解释一下这是什么意思吗？更一般地说，是否有一个网站/一组文档可以解释错误声明的含义？
【问题讨论】：
【参考方案1】：你有这样的声明：
select foo from bar where a=? and b=? and c=? ...
您的代码将值绑定到参数：
st.setInteger(1,123); // goes to a
st.setString(2,"hello"); // goes to b
...
现在，参数 #6 未绑定，未提供任何值。语句不知道将什么值发送到 DB（默认情况下它不会发送 NULL）。如果参数值未知，你应该这样做：
st.setNull(6,Types.VARCHAR);
【讨论】：
【参考方案2】：您可以粘贴您的 PreparedStatement 代码吗？这意味着你有一个额外的？在您没有为其设置值的语句中。
【讨论】：
