 - Java Axis2 Client Calling .NET 2.0 Web Service..I am able to get the call to the .net 2.0 web service with this code:
 
 [code]
 InventoryServicesStub stub = new InventoryServicesStub(null,
 "http://localhost:2067/NGLPTOServices_VS/InventoryServices.asmx/Ping");
 InventoryServicesStub.Ping ping = new InventoryServicesStub.Ping();
 
 InventoryServicesStub.PingResponse response = stub.Ping(ping);
 
 String results = response.getPingResult();
 System.out.println("Response : " + results);
 [/code]
 
 I can see it execute in Visual Studio debugger and return. When control
 comes back to my eclipse debugger, I get the following AxisFault:
 
 "First Element must contain the local name, Envelope"
 
 How do I fix this?
 
 Here is my WSDL:

 - Datasource problames + accessing the, outside of a containerHi,
 
 I'm completely new to J2EE and currently struggling with datasources.
 
 We have a Oracle database we'd like to access via jboss. I've set it up as a
 datasource using the oracle-xa-ds.xml fiel as an example. This appears to
 have worked, in as much as we can now see it via JNDIView .
 
 I'm having no luck actually using it however.
 
 To test I created a servlet containg the following code :-
 
 try
 {
 ic = new InitialContext();
 ic.addToEnvironment("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
 ic.addToEnvironment("java.naming.provider.url","jnp://localhost:1099");
 ic.addToEnvironment("java.naming.factory.url.pkgs","org.jboss.naming.client");
 ic.addToEnvironment("j2ee.clientName", "test");
 }
 catch (NamingException e)
 {
 out.println("Could not create JNDI " + "context: " +
 e.toString());
 }
 
 try
 {
 
 DataSource ds = (DataSource) ic.lookup("java:XAOracleDS":);
 con = ds.getConnection();
 }
 catch (Exception ex)
 {
 out.println("Unable to connect to database. " + ex.getMessage());
 }
 
 This fails telling me that test is not bound.
 
 What am I doing wrong?
 
 Our eventual plan is to have applications access this datasource from
 outside of jboss. I've seen a couple of posts now suggesting that this might
 not be possible. Can anyone confirm if this is the case?
 
 Thanks

 - Problem about JavaMailHi,
 
 I'm just trying to use JavaMail and have a strange problem.
 (See the code snippet below)
 
 When running it, the exception error message is:
 
 errorjavax.mail.SendFailedException: Sending failed;
 nested exception is:
 javax.mail.MessagingException: Could not connect to SMTP host: localhost,
 port: 25;
 nested exception is:
 java.net.ConnectException: Connection refused
 
 the problem is in the line with //!!!!
 If I comment this line out, it works fine.
 
 The purpose of this line to invoke check_server is to
 have a check first.
 
 Who can give me some hints?
 Thanks much!

 I have been bitten by this copy-paste error a few times too. I find that two
 things work really well for me to avoid it:
 
 - Define variables in as narrow scope as possible. For instance, I have
 often found that most of my GUI elements only need to be referenced during
 construction, not during normal operation when all the listeners are set up,
 so most of my buttons, menus, lists, tables, etc, are defined as final
 method variables, where different parts of the GUI is constructed in
 different methods. In extreme cases (like in test code) I have even break
 long methods into a list of scopes to ensure that variables are not "reused"
 without initialization by accident.
 
 - If I copy more than a one or two lines, I stop and think if perhaps it
 would be better to refactor the otherwise copied code into a new method.

 - Difference between 1.3 and 1.4 in JTable?Hi,
 
 I wrote an application that uses a JTable to display some data. I wrote
 my own cellrenderer that provides rows that contain multiple lines of text.
 When a row is deleted all other rows are rerendered and the rowheight para-
 meter is updated accordingly. This works in 1.3. But in 1.4 (I tried different
 JDKs on different platforms (Linux/MacOSX/Windows..) the rowheights are not
 updated. Is there a difference in the evaluation of this in 1.4? Maybe that
 I have to change the rowheigth at a later point in the program?

 unsure on what effect exactly implementing XML in my program will have. It's
 a very simple program (the java files are 35kb in total) - it appears to me
 that if I use XML then I'll have to include a comparatively huge XML parser
 with my program when distributing it - I've just downloaded the IBM one and
 it's 2.6MB. Is this true or am I misunderstanding something fundamental
 here?
 
 TIA.

 - trying to integrate jfcUnit on MavenI have been trying with no success to add the jar jfcUnit.jar on my
 maven project. the main problem is that anytime i am trying to build
 it. I get the following message:
 
 Attempting to download jfcunit.
 WARNING: Failed to download jfcunit.
 The build cannot continue because of the following unsatisfied
 dependency:

 On my project.xml I have defined the jfcunit dependency as follows:
 
 <dependency>
 <groupId>commons-cli</groupId>
 <artifactId>jfcunit</artifactId>
 <jar>jfcunit</jar>
 </dependency>
 
 on the file system itself i have inserted this jfcunit on commons-cli
 directory. I have also added to the classpath, and I have tried on
 eclipse and it works. Nevertheless wnytime i am trying to build a
 project sing maven, i am getting the same error.
 
 I would appreciate any help regarding this matter.

 - custom jtable copy command?Hi.
 
 I am trying to implement a custom behavior on the copy command on
 jtable.
 
 Basically I force the entire row to be selected when a user is working
 with myJtable. I feel this is a good design because it allows the user
 to quickly see what they are working with, without a doubt.
 
 However I would like to customize the copy command on the jtable
 because some of the items in the row are images, which I would not like
 to allow the user to copy (it gets converted into text, and it looks
 ugly!).
 
 What I would like to do is have the copy command ignore the columns
 with the images in them, and only copy the textual columns. Im not
 sure how to go about doing this, does anyone have any insight for me?
 
 Thanks!

 - new java.util.Date(0)Hi,
 
 I'm sure this is some kind of Locale issue and is probably documented in the
 spec, but I looked there and there are many things documented there. It
 would be nice if the experts in this ng could explain the right way to think
 about it.
 
 System.out.println(new Date(0));
 
 yields
 
 Wed Dec 31 19:00:00 EST 1969
 
 I guess this is the time in NY (which is what my computer is set to) when in
 London it was 1/1/1970 00:00am. How can I use Date more generically?
 
 For example, I have code which returns historical temprature. If I ask it to
 return the temprature as of "1/1/1970" it will convert the string to the
 Date (which is Date(0)) and then return the temperature as of 12/31/1969. I
 could artificially add 5 hours, but then it won't work in CA. I could add 8
 hours but then it won't work in Moscow. I could add 1 day, but then it won't
 work in London.
 
 Thanks!

 - a simple question realted to StringBufferHi,
 
 I am using a StringBuffer to hold a line with fixed length of 72 chars.
 Later, I am going to put char at a specified location, using
 setCharAt(location, char) method.
 
 But this code doesn't work:
 <Java>
 StringBuffer line = new StringBuffer(72);
 
 line.setCharAt(5, 'A');
 </Java>
 
 This code works:
 <Java>
 StringBuffer line = new StringBuffer(72);
 for (int i=0; i<72; i++) //make the StringBuffer contains 72 empty chars
 {
 line.append(' ');
 }
 
 line.setCharAt(5, 'A');
 </Java>
 
 I found that this required for loop is ridiculous. Reading the Java
 document of StringBuffer suggests the first version is correct and
 should work. I don't understand it.
 
 Thank you very much for your help.

 - FreeBsdCrypt updatedAlas, I don't have the time to make a proper port of this (but if someone
 else wants to, please do feel free) but since there's an update and folks
 may find this useful, I thought I'd mention it anyway.
 
 FreeBsdCrypt can be found at
 http://spatula.net/software/FreeBsdCrypt-1.1.jar . This contains an
 implementation of FreeBSD-style MD5 crypt, which many have found useful
 when trying to integrate Java stuff with FreeBSD stuff, or migrating from
 other languages to servlets, or whatever.
 
 The jar contains all the API docs, source code, and the complied class.
 Usage is pretty simple anyway:
 
 String result = FreeBsdCrypt.crypt("password", "salt");
 
 The major change in this version is correcting the way the class name is
 capitalized. It needed to start with an uppercase letter since it's a
 class name, and then Pascal-casing the rest of it. Consensus on the web
 seems to be that acronyms of 3 letters or more are to be Pascal-cased.

 - architecture for gui status bar messagesHi,
 
 I have an app (Java not that is too pertinent) which is a fat client
 GUI with a main form, numerous dialogs, wizards, menu actions, toolbar
 functionality etc.
 
 I am looking for a consolidated method for reporting errors. I already
 have code to log the exception, warning, error etc to a local circular
 file.
 
 But I also wish to display an error message to the end user to indicate
 a problem occurred.
 
 I can't stand a popup error message.
 
 Rather I would like to do something similar to Internet Explorers
 active x warning message, where a bar subtly rolls up with a warning
 icon allowing you to click for further information.
 
 While I do throw Exceptions up and up as far as I can - there are many
 places, such as within a custom control where I trap the exception
 early.
 
 So to get the interaction with the main frame (or a dialog) should I
 really pass JFrame or JDialog references throughout my code - or should
 I use the good old global variables...ew...
 
 thanks

 - Weird behavior on allocation...what's going on?Greetings,
 
 I'm working on an application which will be very math-intensive, and
 requires the use of mathematical constructs known as quaternions.
 They are basically 4-vectors and that's all you need to know for this
 discussion.
 
 Here is the offending code snippet in the main():
 
 Quaternion q1 = new Quaternion(5.0, 7.0, 6.6, -8.0);
 q1.print();
 Quaternion q2 = new Quaternion(-4.0, -3.0, 2.0, 1.0);
 System.out.println("q1 and q2");
 q1.print();
 q2.print();
 Quaternion q3 = new Quaternion();
 System.out.println("q3 before multiplication");
 q3.print();
 q3 = Quaternion.mul(q1, q2);
 System.out.println("q3 after multiplication");
 q3.print();
 
 Here is the output I get:
 
 quaternion: 5.000 + 7.000i + 6.600j - 8.000k
 q1 and q2
 quaternion: -4.000 - 3.000i + 2.000j + 1.000k
 quaternion: -4.000 - 3.000i + 2.000j + 1.000k
 q3 before multiplication
 quaternion: 0.000 + 0.000i + 0.000j + 0.000k
 q3 after multiplication
 quaternion: 0.000 + 0.000i + 0.000j + 0.000k
 
 Can anyone explain to me what I'm missing? I'm assuming that by doing
 new, I get two separate instances, init'd as shown, so that q1 and q2
 are not the same thing. FYI, most of the code in the Quaternion class
 is static, so I'm guessing it has to do with some subtle but insidious
 misuse of the static keyword in my class definition. Please help!
 Thanks.

 - Arrays.asList() doesn't work quite like I would think it shouldI've included an example of the problem I've run into. I'm trying to
 randomize an array of integers, much like the following program does.
 Unfortunately when I ask the system to do so, I don't get a randomized
 array. Now normally this wouldn't bother me. I would just assume that
 a new object is being created and then destroyed by the garbage collector
 without my ever seeing it, but in this case it looks like a bug.
 
 Isn't the whole point of the asList() interface to allow this kind of
 thing?
 
 Is this a bug in Java?

 - Jet Version 4.0 is outJET is an AOT (Ahead Of Time) optimising compiler. I use it for nearly
 everything I run on my own machines. Excelsior came out with Jet
 Version 4 today.
 
 This marks some big changes precipitated with a new legal agreement
 with Sun. Some of the changes are good, some distressing.
 
 See
 http://www.excelsior-usa.com/jetlatest.html?ml=jet400
 
 The good news your compiled apps no longer need a Sun JRE installed.
 The bad news is you can no longer distribute self-contained
 executables. You must distribute the ENTIRE JRE in compiled DLL form
 along with your app!! Phht! Why Sun insists on that makes no sense to
 me. I can see them demanding no stripped down JRE, but what difference
 does it make if proprietary complied equivalents are stripped down?
 
 The other good news in the compiler now meets Sun's validation suite
 for compatibility. I never had troubles with compatibility, but is
 nice know that is nailed even better.
 
 Pricing is in flux. My website entry is a bit out of date at
 http://mindprod.com/jgloss/jet.html I will be updating it in the next
 few days with information they sent me.
 
 The big advantage of Jet over java.exe is apps start up a lot faster
 and I can start them with a simple exe name. It makes my apps easier
 to use as command line utilities.
 
 The biggest disadvantage of Jet is you must exactly match DLL with
 app. You can't run old code on a new DLL runtime without a recompile.
 
 So roughly you convert every app and every customer at once to the new
 compiler version. Keeping old compiled code around creates headaches.

 - Creating a Private Key from byte arrayHi,
 
 I have a 256 byte array in my code which I have to use a key in a
 MD5withRSA hash.
 As far as I can tell, in order to use the MD5withRSA algorithm I need
 to use the Singature object.
 In order to initiate the Signature object, I need a PrivateKey object.
 
 How do I instantiate a PrivateKey object using my byte array?
 
 I have only managed to create a SecretKey object with my byte array,
 but the Signature requires a PrivateKey. I can not cast a SecretKey to
 a PrivateKey...
 
 What is the easiest way to create and initialze a new PrivateKey?
 
 Thanks,

 - Cannot start Eclipse on HPUX system - UI HangsHi,
 
 I am trying to run Eclipse 3.1.1 on an HPUX machine (uname -a = B.
 11.11, 9000/800 which I assume means I am running OS 11 on an HPUX
 9000 machine) and I am using a 1.4 JVM. When I start Eclipse it hangs
 on any window/wizard/dialog box that requires input. For example if I
 start Eclipse with no parameters, the workspace window appears where I
 choose my workspace directory. I cannot input any data or selct OK, or
 anything. I am stuck there and need to kill everything.
 
 If I run Eclipse with the -d option then it goes to the normal Eclipse
 start window. Everything looks fine, but again I cannot select
 anything, click on anything or use any menu. Also, the progress bar
 that shows up while starting never quite finishes. There do not seem
 to be any logs created that I can find.
 
 I am running Cygwin from my laptop to connect to the remote HP Machine
 and I am using ssh -Y to start the window/session.
 
 Is there any trick to getting Eclipse to work on an HPUX machine?
 
 Thanks

 - Oracle TopLink + composite mappingHello,
 
 I have a little problem with Toplink:
 
 I have a table in Oracle DB:
 
 table T1 {A: integer, B: integer, C: integer}.
 
 I want to have following mapping:
 
 class X { int A; intB;}
 class Y{ X objct; int C}
 
 so the objct (of class X) is a composite of class Y, and both of
 objects (composite and owner) are in the same table.
 
 Is it possible to make such a mapping in TopLink?
 
 Thanks for every helpful answer.

 - date problems.......hi,
 
 I'm trying to write a little program to send myself email reminders at a
 date in the future... I wrote a little interface in which I send the
 date, body of e-mail.. etc...
 
 problem is date being set is exactly one month into the future from when
 I set it.. if I say, for example, send me e-mail on Dec. 12, when I
 print out date I sent in form, it prints Jan 12, 2007... to wit:
 
 process info sent with request:
 
 sDate = getParameter("date");
 mDate = Integer.parseInt(sDate);
 sMonth = getParameter("month");
 month = Integer.parseInt(sMonth);
 sYear = getParameter("year");
 year = Integer.parseInt(sYear);
 
 set date based on info sent with request:
 
 Calendar calDate = Calendar.getInstance();
 out.println("calDate: " + calDate + " ");
 // this prints confusing stuff.. can't make out exactly
 // what date this returns...
 
 calDate.set(Calendar.YEAR, year);
 out.println("year: " + year + " ");
 // (prints what I expect..)
 
 calDate.set(Calendar.MONTH, month);
 out.println("month: " + month + " ");
 // (ditto..)
 
 calDate.set(Calendar.DATE, mDate);
 out.println("date: " + mDate + " ");
 // (ditto..)
 
 java.util.Date sendDate = calDate.getTime();
 
 out.println("date to send email: " + sendDate + " ") ;
 // this prints a diff date from values that print above...
 // (one month later than date I set..)

 - Who Says What Your Fashion Statement Is?Who exactly should say what your Fashion Statement is? You of course!
 Each of us has our own likes, dislikes comfort zones, body shape &
 size, and life styles. Yes its wonderful to pick up the magazine that
 shows this years top stars like Sarah, Jessica, Nicole, and Gwen but
 hey we aren't them right.
 
 Perhaps my comfort zone is a loose fit, maybe yours is a very tailored
 or tight fit. I like turtle necks, you've got cleavage and like to
 show it. Maybe your a rancher and functional is important, or an
 office executive where a professional look is critical. Tweeds in and
 you hate tweed, then don't buy tweed. Hot colors are in but your skin
 is washed out, then stick to the colors that look good on you but
 perhaps dress them up with a little color. Low rise pants are in but
 they aren't attractive on you, then don't buy them.
 
 It's all wonderful and dandy for the fashion world to tell us what is
 in, what we should wear. But the bottom line is clothes that we buy
 and hang in the closet never to be warn are a waste of our money.
 Don't feel pressured to stay with the trends. Trends come and go. If
