A jsp page is divided in some areas like content, navigation etc. Content -as an example - is dynamically included and should display some - I call them - blocks. A block is for example an image, a list and a headline. So content can have 1 to many blocks. So a page ->content->block->image I'm using the MVC pattern so my first approach was that my controller servlets passes to the jsp page an object called model and the jsp page gets the data out of it. Because of the structure this gets very ugly like: Page onepage = (Page) model.getPage(); and then (Area) onearea = (Area) onepage.getArea('content'); and so on... The second problem is how do I pass the needed objects to the includes..? Actually the jsp-page gets the object and writes it into the request with setAttribute and the included page pulls them out.. But this looks horrible..

Not exactly, no. There is no requirement that classes in the same package are compiled together, nor that they have any dependencies between them. Both are likely, but in the end a package is basically just a prefix at the beginning of the name of a class. As an example, there exists a class called org.w3c.dom.Document, which is a part of the DOM recommendation as implemented in the core Java API. It can also be described as the class in package "org.w3c.dom" with a simple name of "Document". The primary purpose of a package is to avoid naming conflicts. For example, there is also a class called Document in the javax.swing.text package. These two classes have completely different purposes, and you can tell them apart because of their different package names. If you only intend to use one of them, then you can use the "import" statement to tell the compiler that when you write "Document", you actually mean "org.w3c.dom.Document" and not "javax.swing.text.Document" Of course, you can always use the full names if, for example, you need to use both Document classes in the same source file. Packages also play a role in access control specifiers and in the Java security architecture with package sealing. These are secondary to the main purpose of a package. -- www.designacourse.com The Easiest Way To Train Anyone... Anywhere.

[Top-posting fixed] I'm not sure where you're getting that from. Files have nothing to with packages. An implementation of Java such as IBM's old Visual Age product, which did not store source code in files at all, still would need to have packages because they are a part of the Java language. The statement that a ".java" file is included in a package is about equivalent to saying that protective plastic coating on a distribution CD is a part of the Windows operating system. The two concepts exist at different levels, and can't be compared. -- www.designacourse.com The Easiest Way To Train Anyone... Anywhere.

When I call it it deletes a row from my table model, updates the view, and deletes it from the underlying domain model. Except that last step is a desirable *side effect*. The swing model holds a list of domain model objects this is the same list object that is retrieved from the domain model. So as a side effect changes to the swing model affect changes to the domain model. This is fine behaviour for me with this system, though I realise that often more decoupling is desired. The downside is that I don't explicitly call myDomainObject.deleteWhatever() so my intent from pure code is not obvious.

I wonder if I have the answer? At present I have Customer as the highest composer (Nothing maintains a list of customers). I use arrays[] and ArrayList to compose customers. So this is a good reason to have a CustomerList object. I'll make it implement List delegating to a wrapped ArrayList and very little code will change. -- Mike W == 3 of 3 == Date: Sun, Nov 7 2004 12:22 pm From: Oscar kind <[EMAIL PROTECTED]> VisionSet <[EMAIL PROTECTED]> wrote: > My Swing Table model has a delete method. > When I call it it deletes a row from my table model, updates the view, and > deletes it from the underlying domain model. > Except that last step is a desirable *side effect*. [...] > This is fine behaviour for me with this system, though I realise that often > more decoupling is desired. Yes. Preferably, the domain model just is. It doesn't do anything, it is acted upon by the controller. > The downside is that I don't explicitly call myDomainObject.deleteWhatever() > so my intent from pure code is not obvious. > > Thoughts? One. Update the interface when you commit a change in the domain model. This can be signaled by the controller logic (for example when a method on a domain object completed successfully). Advantage is that what you see is the current situation. Changes become atomic, just as in a database; this is a Good Thing. Also: when (for exmple) you create a list to commit, a change is most likely initiated by the user. This is known to the controller, who can then signal an update. The only time when this does not work is when changes come in from the outside (for example with a stock feed). But in that case a listener structure in your domain objects is perfectly natural, and that can signal the controller, etc. -- Oscar Kind http://home.hccnet.nl/okind/ Software Developer for contact information, see website PGP Key fingerprint: 91F3 6C72 F465 5E98 C246 61D9 2C32 8E24 097B B4E2 ========================================================================== TOPIC: Why would file reading stop at 1124 bytes with this code? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/f79ea47a0b0aea21 ========================================================================== == 1 of 1 == Date: Sun, Nov 7 2004 11:16 am From: "Mickey Segal" <[EMAIL PROTECTED]> "Sudsy" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > I hate to mention the obvious, but I don't see an invocation of > setContentLength here.

Thanks for the helpful suggestion - books on Java I/O tend to gloss over such issues.

You mention rows and columns, so I assume you're talking about a 2-dimensional euclidian space where the coordinates are non-negative. In this case, I'd suggest a List of List's. > in the program bulk processing, i 'll have to compare a certain > variable value with the column elements. upon this comparaison, i > might insert this variable in a particular column Thus, I'd use an ArrayList to assign to the List variables. It has better random access than a LinkedList, and if columns aren't removed or inserted (only appended), it's inefficiencies in that area don't surface. > i can think on a vector of vector, but is there not any more suitable > java built-in data structure Vector acts the same as an ArrayList, but has additional synchronization. Do not use it unless you really need that, and even then you're probably better off using a synchronized List anyway: synchronization is just part of thread-safe programming, and is likely to induce a false sense of "ok, that's fixed". It does at least with me. I'd use the List interface and one of the new List classes (ArrayList & LinkedList) instead. -- Oscar Kind http://home.hccnet.nl/okind/ Software Developer for contact information, see website PGP Key fingerprint: 91F3 6C72 F465 5E98 C246 61D9 2C32 8E24 097B B4E2 ========================================================================== TOPIC: How do you report a JIT crash bug? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/6e12e8e3c39c7cc4 ========================================================================== == 1 of 1 == Date: Sun, Nov 7 2004 12:37 pm From: "Mickey Segal" <[EMAIL PROTECTED]> "Sudsy" <[EMAIL PROTECTED]> wrote: > It looks like a call to Component.removeAll is invoking the underlying > Component.removeNotify, which is supposed to disconnect from the native > peer.

We don't think its possible to implement that using Servlet w/ http, so is there any other method that can help us to achieve our requirements ?
