    Should I go for ArrayList of ArrayLists / ArrayList / Something else?

    You don't need to retrieve all the columns to fill the DTO. Just fill the columns that you need. Though I would argue that you should fill everything. Do not performance-tune an application until you have determined performance is an issue. I feel your coupling concern is a weak argument...

    Should I go for ArrayList of ArrayLists / ArrayList / Something else?

    Create a data object to model your database table and then create an ArrayList of these data objects? This is the standard way to deal with this problem. These data objects are typically referred to in J2EE as Data Transfer Objects or DTOs. Take this table: table item { id number primary...

    Memory Leak?

    Don't make the mistake of assuming that their can't be memory leaks in Java Applications. Memory leaks in Java are just much more subtle. The garbage collector only reclaims memory from objects that are no longer actively referenced. Memory leaks in Java result from a central point never...

    Thanks Sedj, but could you look at this?

    Your problem is coming from the fact that Search.readTokens is incorrect. You define the method as returning a String array, which doesn't seem like what you want, yet in the method you define a String array and initialize it as an int array. This is obviously never going to compile. I think...

    ASP to JSP

    Moving from ASP to JSP will be pretty straight-forward with the exception of two things: 1) If you are using custom COM objects in your ASP pages then these will need to be rewritten as Java objects.
