MySQL Connection Pool + Tomcat

ww2020

出現Cannot get a connection, pool exhausted

一台打資料，為什麼會满呢??

Context initContext = new InitialContext();
Context envContext  = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/lsmotor");
Connection conn = ds.getConnection();

try
{}
catch(SQLException e)
{}
finally
{
  conn.close();
}

要改什麼??

你的Java有DB driver吗？
