connection pooling in Tomcat with singleton?

I am using connection pooling in a web application which runs on Tomcat. And I set it up as given here http://tomcat.apache.org/tomcat-7.0-doc/jndi-resources-howto.html#Adding When I need a connection I am calling the following code which is in each request of the servlets Context initCtx = new InitialContext(); Context envCtx = (Context) initCtx.lookup("java:comp/env"); DataSource ds = (DataSource) envCtx.lookup("jdbc/myDBName"); con = ds.getConnection(); Should I initialise ds object as a singleton and get connections from this object instead of getting ds over and over again?

以上就是connection pooling in Tomcat with singleton?的详细内容,更多请关注web前端其它相关文章!
