Hi anyone, I'm still trying to figure it out. I will reinstate the problem now: If I try to connect using the code below, it WORKS: <% InitialContext ctx=new InitialContext(); DataSource ds=(DataSource)ctx.lookup( "java:PostgresDS"); Connection con=ds.getConnection(); con.close(); If I try to this one, it DOESN'T WORKS: <sql:setDataSource dataSource="java:PostgresDS" /> Anyone knows why?
