To give a really extreme example, let's say you're writing something akin to MapQuest driving directions. Although this does access large amounts of data in the form of the locations of various roads, the core task is a computational one, and data is only secondary. > I think that I can make all with RowSet, but maybe I mistake! No, of course you can do all database access with RowSet. You can also write all possible programs in assembly language. You can also make do without databases entirely and use flat files for everything. These things are all possible. However, O/R mappers make some code easier to write, easier to understand and maintain, and quicker to the market than a lower-level interface like RowSet. -- www.designacourse.com The Easiest Way To Train Anyone...

The most significant aspect of your description above is not that it's batch processing, but that it doesn't sound much like a very complex task. If your task lacks complexity, then most design patterns are pretty much irrelevant anyway.

As far as most of us are concerned, any questions that are generally useful in Java programming are appropriate for this newsgroup. Unfortunately, there are an increasing number of netcops around lately who start every message by telling you what you should have done differently. I'd just ignore them if I were you.

You're entirely missing the concept of abstraction. You should really have something like this: public class MyDataRecord implements Comparable<MyDataRecord> { private String name; private float value; private int i1, i2; ... public int compareTo(MyDataRecord other) { return Float.compare(value, other.value); } } That use a Vector of those. You mentioned that the display of this data in a Swing table is in another program, and there's nothing wrong with using different data models for the same data in different programs. However, if you would like to use a JTable to display the data in this form, just define a subclass of AbstractTableModel to define a mapping from a Vector<MyDataRecord> to the TableModel interface. You'll define what field goes into what column by your implementation of getValueAt (and probably getColumnName and getColumnClass as well). -- www.designacourse.com The Easiest Way To Train Anyone...

I encounter serious problems when I try and build the document using any DOCTYPE preset. My algorithm, should a DOCTYPE be needed in the final Document, is to 1. Create a DocumentBuilder from a DocumentFactory 2. Get the DOMImplementation from the DocumentBuilder 3. Ask the DOMImplementation to create a DocumentType object with some presets. 4. Use that DocumentType to help create a new Document using the DOMImplementation 5. Create a DOMBuilder on that Document, using the root Node of the Document as the current Node so that any further events are built from that node. The problem I'm getting is that the DOMBuilder seems to think that I am appending multiple elements to the root of the Document instead of the root Node. To illustrate this, I'm inserting some source that should be runnable using standard J2SE 1.4.2 runtime libraries. This example will illustrate my frustration.

In the documentation for the java.lang package, there are the following classes/interfaces listed. Comparable<T> Iterable<T> ThreadLocal<T> java.util has these among others Collection<E> Comparator<T> What do the <T> and the <E> and the <K,V> mean? They look like parameters, but I do not recognize the format. If this is part of a standard documentation format, please feel free to point me to some documentation on the format and I can read up on it myself. Thanks. == 2 of 3 == Date: Mon, Dec 27 2004 3:04 pm From: "Robert kebernet Cooper" Those are part of the new Generics system. They really don't mean anything except are shortand to let you know of the application of Generics in the current class. The only ones that are really meaningful are the <K, V> for key type and value type. http://www.fawcette.com/javapro/2004_03/online/j2ee_kkreft_03_10_04/ == 3 of 3 == Date: Mon, Dec 27 2004 11:56 pm From: "Tony Morris" "PatFan15" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > I am new to Java and I am reviewing the online class documentation from > Sun.

I am developing a GUI. I'm not quite sure what to do when i encounter listeners. To keep things tidy, i create a new class which implements a listener that i want to use, then join that listener to a component. For example, a listener that is called when a JTree node is selected is called BuildTreeSelectionListener (implementing treeselectionlistener). Then i use buildTree.addSelectionListener(new BuildTreeSelectionListener). What i dont get is this... BuildTreeSelectionListener is called, and gets the node that has just been selected. I now want this class to reference a method onNodeSelection in my gui class (SwingMainView). To do this, i have to set that method to static, then call SwingMainView.onNodeSelection(). To me this doesnt seem like good code? What do people usually do? Do they just implement the listener in the class that it has been called from, instead of creating a new class for it? On a totally different point, has anyone got a good resource for the proper use of keyword 'super'. I cannot find one. ============================================================================== TOPIC: Runtime.exec - no access to ports ? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/129ba54a793c2382 ============================================================================== == 1 of 1 == Date: Mon, Dec 27 2004 3:27 pm From: Darek Danielewski I'm running a simple Java class utilizing Runtime.getRuntime().exec(String) to execute an external application. During execution process, the app will eventually attempt to communicate with some port on same machine, say 51002. Unfortunatelly, this attempt is denied, I'd have to assume by JVM itself, as the external app works perfectly fine from a DOS prompt. Am I missing something in the permissions? I've used an allow all policy file like this: grant { permission java.security.AllPermission "", ""; }; Help would be greatly appreciated.
