Writing a Standalone Client For Secure Web Service

Today I was puzzled writing a standalone Java client (going to be Swing app) that "talks" to the remote server, which serves a secure Web Service. Looking around various blogs and other stuff, I made it. It even works as expected. :-) 

But I want now put it all together to make it very clear and up to date. The process is all undocumented properly and successfully allows everybody hit the wall with the forehead. Therefore, to avoid others had the same sad experience googling around for a half a day, soon I am going to make a end-to-end document with a screenshots and detail explanations.

Uugghhh... Now is Friday and 8:30PM. Maybe tomorrow...

Writing a Secure Swing Client For a Web Service

Using NetBenans IDE, I've tried to write a Swing GUI client for a secure web service that I've made. While web-based servlet works great, Swing standalone application spits weird errors and won't even run. One of the interesting exceptions is:

javax.xml.ws.soap.SOAPFaultException: ERROR: No security header found in the message
...

The problem is that NetBeans is using "old" JAX-WS libraries instead using WSIT. Solution is to remove all the JAX-WS jar libraries that NetBeans added automatically, when created Web Service Client reference and replace them with the libraries from GlassFish application server.

To those, who need step-by-step instructions:

1. In NetBeans IDE, right-click on the client project and select "Properties". "Project Properties" dialog appears.
2. From the "Categories" tree at the left side of the dialog, select "Libraries" item.
3. Remove all the JAX-WS libraries—do not worry, your project is completely broken anyways. :-)
   
4. On the right side of the dialog, click on "Add JAR/Folder" button. "Add JAR/Folder" dialog appears.
5. Browse to $GLASSFISH_HOME/lib folder (and subfolders) in order to select all the libraries, listed below.
6. Click OK.
7. Have fun. :-)
   

If everything else is correctly configured (e.g. your X509 and/or SSL cert's etc) then it should work now fine. Here a full list of the libraries you want to add (some of them are in lib/endorsed subfolder):

• activation.jar
• appserv-deployment-client.jar
• appserv-launch.jar
• appserv-admin.jar
• appserv-ext.jar
• appserv-rt.jar
  
• javaee.jar (oh my...)
• webservices-rt.jar
• webservices-tools.jar
• webservices-api.jar

It will eat you 34 megabytes of disk space and 40 megabytes when running. While it looks fat, still I am much more satisfied using Swing over Java Web Start (JNLP) rather than use web browser based DHTML pages (current buzzword for DHTML now is "Ajax"). Ajax UI "eats" much more memory actually. It is significant performance problem on the Enterprise, when terminal servers for lots of users are in use.

16 Million Of Terabytes On a Laptop

Apple did great OS! Mac OSX supports 16 million of terabytes of virtual memory on... single small laptop! I am serious. Here is the evidence:


Awesome, isn't it? :-)

Java Swing Balloon Tip

I am developing a GUIs with Java Swing. Awesome, everything fine. Now, today I needed something like tool-tip or balloon pop-up to show various messages. In particular, I find that there are no standard form validation framework, so I created one, ripping off ideas from Zope Formulator. And the validation trigger suppose to pop-up a balloon tip when something wrong and focus the widget. That's fine, validation works perfect, unless you need a balloon tip.

I found one "decent" balloon tip on https://balloontip.dev.java.net/ site. Here how it looks like in Windows with Metal L&F: (pic is taken from the site directly):

Well, it's OK. It's Windows and mostly everything looks ugly there even in Vista, so a combination of blue frame on bluish gray with a squarish hint might be OK for environment that lacks taste and design. But what about Mac? — yeah, I am snob-like a--hole here, sorry. OK, what about Gnome or KDE on Linux and/or Sun Solaris? Windows is not the only OS these days anymore. So here how the whole thing looks like in Mac:


Notice ugly corners and quite crappy close button, not mention that a close button does not fits into a balloon tip paradigm. Well, my double-advice to all Java developers who sticks on Windows platform (there are two messages in one):

People, PLEASE install Linux and/or Solaris to make sure you are NOT providing funny things!..

*sigh*

So and now this is how it should look like (took for me less than two hours to rework entire source code, throwing lots of things):


Now I am happy. :-)

P.S. And yes, it does not need a close button — just click on it...

Crippled Apple LaF for Java Swing

Recently I found very-very unpleasant thing with Apple Look & Feel for Swing on OSX. On JDesktopPane, to get all the internal frames getAllFrames() is called. Works fine everywhere except OSX: it does not returns iconified frames. The reason, because they are not JInternalFrame.JDesktopIcon instances as normally everybody else in the World does, but are apple.laf.CUIAquaInternalFramePane.Dock instead. WTF?.. At first, I wanted to abandon OSX LaF and use something else instead. But "Substance" release that works on Java 5 is hell buggy and still very ugly on the same Java 5. New Nimbus LaF is really cool, look great, works and feels awesome, but... looks like an alien in OSX reminding me all this GTK things with X11. Additionally, it does not run on Java 5 at all.

Why Java 5? Yes, it is old, but thanks to (inaudible) Apple, there is no Java 6 on Tiger that the whole thing should also run. In fact, Apple LaF is the best for Java 5, allows font anti-aliasing, behaves correctly as OSX app should and overall looks great, so I do not really want to abandon entire LaF either.

Thus ss a consequence, to get code working everywhere without tweaks and if/else uglyness to detect what platform it runs on, I had to implement my own window tracker.

* * *

Works fine, but still pisses developers off, when everybody have to have dozen workarounds or class extensions to fix here/there various "broken bones".

Apple wants to go Enterprise? Steve, which object of your body you use when you are thinking about Java versions interoperability (an enterprise industry standard, no matter somebody wants to accept it or not) between OSX versions? So what should I do if I have heterogeneous environment with various Macs and PCs and want to go with less old stuff (soon we will have Java 7, while Apple is enforcing me to use Java 4 or even 4)?.. Right: throw macs away from the Enterprise, because they are not compatible between each other, install PCs and bite yourself for other things they brings to you... But to get rid of most advanced desktop OSX workstations is what I definitely do NOT want to do either.

Very stupid.

HDR Image

This is my very first HDR image:

Nothing really special, except that I found (once again) for buying cheap stuff is always equals to losing your money. In my case I bought a cheap tripod. As a result, HDR image is not really crisp and sharp, because camera slightly change position per each frame. :-(

Screenshots Series

Few funny (or not) screenshots I took recently.

First one — Sun Solaris 10 installation. I did not noticed it much before, but that's how bad design of UI installers done. The question is: why do I need to see huge Solaris logo twice and who needs to read stupid useless incomplete Help hint that says for to go to next screen I have have to click on button "next"? Who need this screen and why there are no any functionality on it? They could use this amount of space to do something actually useful: agree to licence or start selecting components etc. No, instead you see this:

You think it is only this one screen? No. If you go through entire Solaris installation (that is unable to complete on my hardware, unfortunately) you will see lots of things like this everywhere. Instead, OpenSolaris looks indeed very promising and actually cool. Some people have complains for packaging, but that's other topic. :-)

The next one is on Dell website. Not much comment for this new Linux logo on the left side:



The third one is from apple.com and is interesting. On the site with series of video-based "howto" is a title: "Find out how". While watching a movie, I captured this frame that shows interesting combination. The only question is: find out how what... If the context is "how to configure XRaid with XServer and find why it always does not works properly", then the answer is probably just in front of you on the cover-flow... :-)
