What's in Spring 3?

One session talked about the upcoming Springframework 3.0. It is more annotations, support for validation in JPA/Hibernate beans. Most interesting is that Spring will solve the REST-problem in Java. Python and Ruby has already solved it. JAX-RS does not solve it in Java. It does not support a way to negotiating what format the result should be in (JSON, XML, HTML etc). Spring 3.0 solves this. So this will be very usefull. Spring 3 will be available early this summer.

The conference has ben good so far. Two days to go. I have also attended a talk about performance tuning of Tomcat and a more detailed talk about Roo wich I mentioned from the keynote.

Create your own CA with TinyCA2 (part 1)

Image
A Certificate Authorities (CA) issues certificates to people and organization that gives us the possibility to know that we surf to the right web site and not a phising site. This concept can be nice to use on your private sites too, but you may not want to spend a lot of money to get a certificate for your site. Most common when one installs a web-mail server at home is using a self signed certificate. When one surf to the web-mail server from a friends computer one can not be sure that nobody listens to the traffic if one not verifies the signature of the self signed certificate. Maybe an easier and definitely a more scalable solution to this is to create ones own CA structure. When we are ready with this how to you will have installed a certificate on your web server, installed the root certificate into your Firefox, and you will have the root certificate stored on a USB-memory stick. First time you want to read your mail from a friends computer you install the root certificate f...

Create your own CA with TinyCA2 (part 3)

In this final part we will add our own root CA certificate to Ubuntus pre-installed certificates. (Part 1 , Part 2 ) Copy your root CA certificate, that we exported in the previous part, to /usr/share/ca-certificates/. Add the file name to /etc/ca-certificates.conf and run the command: sudo update-ca-certificates Most of your services will now be able to find your root CA certificate. To bring your root CA certificate to your friends, just copy the exported root certificate-file to a USB-memory. Using your own CA you can now add support SSL to different services like CUPS, postfix(AUTH SMTP), dovecot (IMAP) etc. You can also create certificates to sign and encrypt your e-mails.

Google Web Toolkit in an Linux 64-bit environment

I have started to take a closer look at Google Web Toolkit (GWT). It looks very nice giving me the possibility to debug AJAX-clients and removing the need for quirks for different browser (read MS IE). Unfortunatly GWT is only shiped as 32-bit and I am running a 64-bit Ubuntu 8.04. The SVN-repository of GWT include some pre-compiled libraries which are compiled for 32-bit Linux. The easy way is to download and install a 32-bit Java from Sun. Following the GWT getting started got me up and running. But I wanted to use my usual Eclipse in 64-bit version. So I started Eclipse and imported my lab project according to the instructions. Then it was time for some settings. First, add the 32-bit Java as an JRE to Eclipse: Open the Window menu and select Preferences. Select Java and then Installed JREs in the tree menu to the left. Select add and pointed out where you installed your 32-bit Java and closed all the dialogs. Now its time to connect the GWT-project to the 32-bit Java. Right click...
