ApacheCon EU 2008 – Amsterdam

March 20, 2008

ApacheCon

Apache goes back to A’dam!

It’s fun-time again for the open source addicts: the Apache folks are back in the Netherlands (hotel Movenpick in Amsterdam) as last year.

Find schedule and all other details at the ApacheCon site.

I definitely recommend going: I attended last year and it was great. Lots of interesting sessions about state-of-the-art technology such as Axis2, Lucene, RESTful services, Web2.0, blogger API, Apache XAP, etc.. and many more.

I especially enjoyed the “Comparing Jave Web Frameworks” session, an enlightening overview of the most popular Java frameworks (Struts2, SpringMVC, JSF, Tapestry, Wicket,..). Excellent speaker (Matt Raible) who shared some priceless thoughts based his on experience.

Tips for ApacheCon-goers

Not to be missed in the DAM:

  • Brouwerij ‘t IJ (Funenkade 7): the amazing brewery in the windmill. Excellent beer (Zatte), unique atmosphere.
  • Pata Negra II ( Reinwardtstraat 1): best Spanish restaurant in town.. con tapas de puta madre
  • Bimhuis (http://www.bimhuis.nl/): Jazz music every night, next to the Movenpick
  • Rent a bike: Amsterdam is a different world on 2 wheels

Enabling SSL on JBoss 4.2.0

March 17, 2008

One of the prerequisites in order to install and configure CAS (Central Authentication Service), a popular open-source Single Sign-On, is to enable SSL on the web container. This can actually be quite painful, especially for developers who enjoy focusing on the implementation details rather than the infrastructure aspects (that would be me 😉 ).

In this post I present the steps required to enable the SSL support in JBoss 4.2.0: JSSE is required (bundled with JDK 1.4 or higher).

Little tip: when prompted use changeit as password as it is the default keystore password.

Delete existing certificates

This is step is not strictly required but it helps to get rid of previously created certificates (in case you have been playing around with the keystore). Run the following commands:

keytool -delete -alias localhost
keytool -delete -alias localhost -keystore “C:/Program Files/Java/jdk1.5.0_14/jre/lib/security/cacerts”

The first command removes the certificate with alias localhost from the user keystore, the second deletes the certificate from the system trusted certification repository.

The cacerts file is basically the system keystore which stores the CA (Certification Authority) certificates and can be found at ${java.home}/jre/lib/security/cacerts
