How to configure Struts connection pool
843838Apr 1 2006 — edited Apr 2 2006I use struts-1.2.9,and want to configure a connection pool,so I configure struts-config.xml file
<struts-config>
<data-source key="bb1" type="org.apache.commons.dbcp.BasicDataSource">
<set-property property="driverClassName" value="sun.jdbc.odbc.JdbcOdbcDriver " />
<set-property property="url" value="jdbc:odbc:SMS"/>
<set-property property="maxActive" value="5" />
<set-property property="username" value="administrator" />
<set-property property="password" value="123" />
<set-property property="autoCommit" value="true" />
</data-source>
....
</struts-config>
Then I use this configure in a jsp file,like follows:
<%@page import="java.sql.*"%>
<%@page import="javax.sql.DataSource"%>
<%@page import="javax.naming.*"%>
<html>
<body>
<%
try{
Context initCtx=new InitialContext();
System.out.println("ok");
DataSource db = (DataSource)initCtx.lookup("java:comp/env/jdbc/bb1");
System.out.println("db="+db);
Connection conn = db.getConnection();
System.out.println("conn="+conn);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM abc");
out.println("User-list"+"<br>");
while(rs.next()){
out.print (rs.getString(1)+"<br>");
}
rs.close();
stmt.close();
conn.close();
}catch(Exception e){
out.print(e);
}
%>
</body>
</html>
When I run this jsp file,it raise follow errors:
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
Where error is in my code? Please give me some examples about how to configure connection pool in Struts and how to call this connection in JSP file and JavaBean.
Thanks in advance!
