Class.forName( "com.informix.jdbc.IfxDriver ").newInstance();
String url = "jdbc:informix-sqli://123.45.67.89:1533/testDB:INFORMIXSERVER=myserver;
user=testuser;password=testpassword ";
//testDB为你的数据库名,myserver是你数据库服务器名字
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from test ";
ResultSet rs=stmt.executeQuery(sql);
还需要informix 的jdbc开发包
没有我可以发给你.留下mail

Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql= "select * from test ";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为： <%=rs.getString(1)%>
您的第二个字段内容为： <%=rs.getString(2)%>
<%}%>
